Description

  The present invention relates to a data display control technique, and more particularly to a data display control technique suitable for selecting, processing, and executing target data from a plurality of data.

In recent years, with the development and popularization of information technology, the number of data handled by a single information processing apparatus has increased, and the types of data have also varied.
For example, in the car navigation system, even if it is map data, it corresponds to a plurality of map data formats, and even if it is the same spot, it handles a plurality of data with different scales. Music data and video data are stored in the car navigation system in units of thousands of songs so that the user can freely view the music while driving.
In addition, information processing apparatuses have been downsized in recent years, and in addition to PCs (Personal Computers), there are restrictions on user interfaces compared to PCs such as mobile phones, car navigation systems, music players, and portable game machines. The situation where a large amount of data is handled in the same way is increasing.
Therefore, in order to make it easy for the user to select the target data on an embedded device with a limited user interface, a list of data to be selected according to the situation is displayed, and the user becomes a selection candidate. The mainstream method is to select data by moving the focus and focusing on the target data.
At that time, in order to access all data at high speed when the number of data is large, high-speed continuous focus movement in the direction while the user holds down the movement button for a long time Focus movement is often implemented.

However, there is a drawback that it is difficult for the user to recognize which data is focused during the high-speed focus movement because the high-speed focus movement is too fast.
For this reason, even if the user interrupts the high-speed focus movement in the vicinity of the target data, there are many situations where the target data is overrun, or conversely, the target data is not reached.
For this reason, there is a burden on the user to perform adjustment to move the focus to the target data after the high-speed scroll is interrupted.

  As a prior art to solve the above problems, analyze the contents of the data display, and if the data that is highly important to the user is displayed, reduce the scroll amount to describe the important contents A technique has been developed that makes it easy to see the scroll without stopping at the place where it is placed (for example, Patent Document 1).

Japanese Patent Laid-Open No. 11-312038

However, the technique described in Patent Document 1 has a problem that it cannot be applied to a data selection screen without scrolling.
Further, there is a problem that even if the scroll speed is changed, the user cannot intuitively recognize which data is important and how important.
Therefore, the user can only benefit from the above technology only in a situation involving scrolling, and the user is forced to determine which data is important within the screen.

  In view of the above background, the present invention allows the user to easily select the target data and how important the data is when the user selects the target data from a large amount of data set. The main purpose is to allow the user to intuitively determine whether there is.

An information processing apparatus according to the present invention includes:
A display that displays a plurality of data in a predetermined order and displays on the display device display information that indicates a state in which any of the data is focused and indicates a state in which the focus sequentially moves between the data according to the order. A control unit;
An importance management unit that manages the importance for each data indicated in the display information;
A focus control unit for designating a focus maintaining time based on the importance of data for each data when the focus sequentially moves between data according to the order indicated in the display information; Have
The display control unit
The focus sequentially moves between data according to the order, and display information in which each data is focused is displayed on the display device during a focus maintaining time designated by the focus control unit. .

  According to the present invention, the focus maintaining time is determined for each data based on the importance for each data, and even when the focus is moved, each data is kept in focus during the focus maintaining time. The user can surely detect important data, and the convenience of the user in selecting data can be improved.

Embodiment 1 FIG.
1. Outline of Embodiment 1 In this embodiment, a table for storing the importance for each data based on the number of times selected by the user is held, and the item of the data is focused according to the importance. An information processing apparatus that controls the focus maintenance time (hereinafter also referred to as focus time) will be described.
Here, the focus maintenance time is a time during which focus is maintained on the data.

As illustrated in FIG. 4, the information processing apparatus according to the present embodiment is an apparatus that can display display information on a display device such as a liquid crystal display 402.

The display information indicates a plurality of data in a predetermined order, indicates a state in which the focus 504 is applied to any data, and the focus 504 sequentially moves between the data according to the order of the data based on a user operation. Indicates the state of going.
When the focus 504 sequentially moves between data at high speed, the time during which the focus 504 is continuously applied to one data is the focus maintenance time.
The focus maintenance time is specified based on the importance of data.
In the information processing apparatus according to this embodiment, the focus 504 sequentially moves between the data at high speed according to the data order, and display information on which each data is focused during the focus maintaining time is displayed on the display device. .
The high-speed movement of the focus is started, for example, when the user performs a long press or a continuous press on a specific button or key of the information processing apparatus.
The information processing device detects long presses or continuous presses of specific buttons, keys, etc., and moves the focus at high speed. When the focus moves to highly important data, the focus on that data is maintained for the focus maintenance time. To maintain.

Since the information processing apparatus according to the present embodiment operates as described above, it is possible to lengthen the focus maintenance time for important (well-selected) data, and for this reason, the user is important (well-selected). ) Easy to select data.
Moreover, although the technique of said patent document 1 is applicable only if it is accompanied by a scroll, in the information processing apparatus which concerns on this Embodiment, also when it is settled on one screen (when a scroll is not accompanied). Can be applied.
Details of the information processing apparatus according to the present embodiment will be described below.

1.1. Description of Functional Block Diagram and Device Block Diagram FIG. 1 shows a configuration example of an information processing device 100 according to the present embodiment.
FIG. 1 shows only the minimum functions for explaining the main operation of the information processing apparatus 100 according to the present embodiment, and elements not shown in FIG. 1 can be added.
Here, an outline of the components of the information processing apparatus 100 of FIG. 1 will be described, and details of each component will be described later.

In FIG. 1, a state control unit 101 is means for managing what state the information processing apparatus 100 is currently in.
In addition, the display control unit 102 displays the display information illustrated in FIG. 5, that is, a plurality of data in a predetermined order, indicates a state in which any data is focused, and focuses according to the data order. Display information indicating a state of sequentially moving between the data is displayed on the display unit 108.
The focus control unit 103, based on the importance of the data, determines the focus maintaining time during which the focus is continuously applied for each data when the focus sequentially moves between the data according to the order of the data indicated in the display information. Specify. More specifically, a longer focus maintenance time is specified for data with higher importance.
The importance level determination unit 104 determines the importance level of each data listed in the display information. The importance is determined based on, for example, the number of selections by the user for each data, the selection frequency, and the like.
The importance storage unit 105 stores the importance of each data determined by the importance determination unit 104.
The importance level determination unit 104 and the importance level storage unit 105 are examples of the importance level management unit.
The data storage unit 106 stores various data necessary for the operation of the information processing apparatus 100.
The input unit 107 is a means for inputting an instruction from the user.
The display unit 108 is a display device such as a liquid crystal display, and presents display information from the display control unit 102 to the user.

FIG. 3 is an apparatus block diagram (hardware configuration example) of the information processing apparatus according to the present embodiment.
The functions of the functional blocks shown in FIG. 1 are realized by the device blocks shown in FIG.

A CPU (Central Processing Unit) 301 is a central processing unit for performing overall control of the information processing apparatus 100, performs processing in cooperation with other apparatuses, and maintains and executes functions as the information processing apparatus 100. It is a device to do.
The CPU 301 executes a service application to be provided as the information processing apparatus 100 based on data or an executable file stored in a ROM (Read Only Memory) 302, a RAM (Random Access Memory) 303, and an auxiliary storage device 306. The entire service application is maintained and executed by performing processing based on input from the input device 305 and outputting the result to the display device 304 or starting new processing.

The ROM 302 is a non-volatile storage device, and the content recorded therein is permanently maintained even when the information processing apparatus 100 is turned off.
However, since the information processing apparatus 100 cannot write data to the ROM, the ROM 302 is used to store data and executable files that are permanently required as the information processing apparatus 100.

Unlike the ROM 302, the RAM 303 is a storage device to which the information processing apparatus 100 can write data. The RAM 303 is divided into two types: a volatile memory that can hold data recorded therein only during a period in which power is shared with the information processing apparatus 100, and a non-volatile memory that can hold data even after the power supply is cut off. Although classification is possible, the information processing apparatus 100 may hold both volatile memory and nonvolatile memory, or both.
In the information processing apparatus 100, data temporarily required during processing is recorded on the RAM 303, and is used for the CPU 301 to perform processing using the data.

The auxiliary storage device 306 is a storage device including a medium for recording / holding data and a drive for reading or writing data to / from the medium.
The auxiliary storage device 306 has a drawback that the data transfer speed is lower than that of the ROM 302 and RAM 303, but can store and store a larger amount of data than the ROM 302 and RAM 303.
For this reason, the information processing apparatus 100 is used to store a large amount of data that cannot be stored in the ROM 302 or the RAM 303.

The input device 305 is a device used to input information to the information processing apparatus 100 from a user of the information processing apparatus 100.
If the user is a person, a device such as a switch, a keyboard, a pointing device such as a mouse or a trackball, a device such as a touch panel or a joystick that inputs information by directly operating the input device, a microphone and voice recognition This is a combination of a video camera and image recognition, or a device that performs input in the form of voice, sound, images or gestures without directly operating the input device. An apparatus that measures an electrical signal or the like and handles the electrical signal as an input can be considered.
The input device 305 notifies the CPU 301 of the input information, and the CPU 301 interprets the information according to the current processing state and performs processing based on the interpretation.

The display device 304 is an information output device used for the information processing device 100 to present a processing result or the like to the user.
More specifically, when the user is a person, information such as a CRT (Cathode Ray Tune) or a liquid crystal display optically presenting the information to the user as a still image or video, or information such as a Braille display A device for recognizing an image with a human tactile sensation, a device for recognizing information as a sound by using a speaker, and the like can be considered.

1.1.2. State Control Unit Next, detailed description of each functional block in FIG. 1 will be given.
The state control unit 101 is a means for managing what state the information processing apparatus 100 is currently in.
The state control unit 101 holds state transition information expressing how all possible states are related when the information processing apparatus 100 performs a service, and the current state is included therein. Always keep track of which state is.

1.2.1 State Information State transition information is information that mainly represents a state.
The state transition information is configured by state information exemplified in FIGS. 21, 53, 54, and 55.

The state information includes a state ID that can uniquely identify each state, a state name that is a name for the state, display control information that describes the content to be displayed in that state and the display control method, and the content that is to be displayed in that state. Focus control information that describes the list information related to the data that can be focused by the user via the input unit 107, the focus movement method between the data in the list in accordance with the input from the user, etc. , And processing / transition information describing the contents to be processed in the state and the state to be transitioned with the processing.
Since the state ID may be of any type as long as the state can be uniquely identified, it is assumed here to be an integer value.
21 shows the overall configuration of the state information, FIG. 53 shows the details of the display control information that is one element of the state information, FIG. 54 shows the details of the focus control information that is one element of the state information, 55 shows the details of the processing / transition information which is one element of the state information.

1.2.1.1 Display Control Information As shown in FIG. 53, the display control information includes an object information list that lists objects that may be displayed when the status is displayed, for each type of object. Object type common display rules that can be described in common, how to display them, and display change rules that describe how display contents should be updated for input information and event information passed from the upper level Etc. are included.
However, if the object type common display rule and the display change rule are not changed for each state and are fixed throughout the information processing apparatus, the display control information need not be included in the display control information. 102 may be incorporated in itself.
In addition, when reusing the object type common display rule or display change rule used in the state of the transition source for that state, a method of describing the use of the transition source rule for each information as a rule, Alternatively, a method of not storing the rules to be reused in the display control information may be used.

The object information list stores information on all objects to be displayed in that state.
For example, when an HTML (HyperText Markup Language) content is a display target, various tags and text are handled as objects.
Among them, for example, the <button> tag can be classified as a button type for displaying as a button, and the text can be classified as a character string type for displaying as a character string.
A collection of common display rules for each type is combined into a common display rule for object types.
For example, the <button> tag describes how to display the default setting, for example, a display rule such as displaying specific image data as a button.
The objects are classified into a selection target object that can be focused and a non-selection target object that cannot be focused.

The object information includes an object ID that can uniquely identify the object, and object-specific display information that is a display rule unique to the object.
Since the object ID may be of any type as long as the object ID can be uniquely identified as in the state ID, it is assumed here to be an integer value.
As the object-specific display rule, a rule depending on the display method and the object type is described. For example, if it is a <button> tag in HTML content, the display position, button size, button background / foreground color in the entire display content Specific information necessary for each object when the display control unit 102 actually generates display information on the display unit 108, such as a button name, a button name display font, and a button name arrangement rule, is described.
In addition, when some control is driven by an operation by a user like an object such as a button, a notification ID that is a driving condition and a processing content to be driven may be described.
The object-specific display information is set to have a higher priority than the object type common display rule. When different values for the same parameter are set for both, the value of the object-specific display information is used.
By providing such priorities, it is possible to describe the default setting display rule for the object type in the object type common display rule and the object-specific display rule and display information in the object-specific display information. There is no need to store a rule for each object, and the data size can be reduced.
In addition, for example, in the case of an information processing device that outputs route guidance in a car navigation system, if the object is a normal route guidance type object, the output intensity is normal, the output voice is female, the output speed is low, and the danger detection guidance type If the object is an object, the output intensity is strong, the output sound is male, the output speed is a little high speed, etc. Even if it is a display means other than the image display, it is possible to describe information related to the object display.

  The object type common display rule includes type common display information commonly used in display control of the object type, type specific display information structure representing the data structure of the object specific display information corresponding to the object type, and type common display. A common type display rule describing how display control is performed using information and type specific display information is included.

The common type display information includes display information that is commonly used for object types depending on the display method.
For example, initial values relating to information not specified in the object-specific display information, values used in a fixed manner, and the like are described.
The common type display rule also describes what specific display control should be performed using common type display information and common object display information common to object types depending on the display method.
For example, in the case of an object type corresponding to the <button> tag of HTML content, the button name is displayed on the display unit 108 as what kind of image is specifically displayed as a button. Is described.

  In the display change rule, a change rule indicating what display change should be made according to the content when the display control unit 102 receives a notification from another means is described, and the content of the notification can be uniquely identified Individual change IDs and specific change rules are described.

There are notification IDs corresponding to input information notified from the input unit 107 and information corresponding to event information notified by internal processing.
In addition, in the case where a means for communicating with an external device is provided, there may be information corresponding to other notification information such as external event information.
Concerning the focus display, use a conditional branch that states what display method is used when the object is in focus in the individual change rule, and what display method is used when the object is not in focus. It is expressed by the rule that was.

1.2.1.2. Focus control information As shown in FIG. 54, the focus control information includes a selection target list in which object IDs of selectable objects that can be focused are accumulated, and the selection target information that is each element of the list includes an object ID. When the focus control unit 103 determines that the focus should be moved when receiving a notification from another means in a state where the selectable object corresponding to the is in focus, which object ID is in the case of which notification ID In order to describe whether the focus should be moved to the selectable object, a focus control rule consisting of an element including a notification ID and an individual control rule is attached.

The focus control description is, for example, the focus control description regarding the case where the cross key or the like is operated by the user when the object A corresponding to the <button> tag when the HTML content is displayed is focused. When the down key is pressed, transition is made to the selectable object B that is closest to the object A on the upper and lower sides of the display. When the upper key is pressed, there is no selectable object that is closest to the upper side of the object display. Therefore, control information such as no focus movement is described.
However, the focus control description does not depend on the state or the focused object and does not need to be included in the selection target list if it is fixed throughout the information processing apparatus.
In that case, the focus control unit 103 itself may be incorporated, and both the focus control information and the focus control unit 103 have information related to the focus control description and are integrated so that necessary and sufficient focus control as a whole is achieved. It is also possible to configure so as to be possible.
Also, as in the above example, specific information about the object to which the focus is moved is omitted when it is determined by the relative positional relationship when all objects in the object information list described in the display control information are displayed. In that case, the rule describes the destination object abstractly, for example, when the down button is pressed, control information based on the condition that the focus moves to the nearest selectable object on the lower side is described. Is done.

1.2.1.3. Processing / Transition Information The state control unit 101 receives input information from the input unit 107 and determines whether or not it is necessary to transition to another state based on information described in the state information corresponding to the current state. If necessary, state transition processing is performed.
In addition, various processes such as service logic processing such as activation, termination, and control of service logic provided to the user by the information processing apparatus upon receiving input information, display processing related to object operation and focus movement displayed on the display unit 108, etc. Issue a start trigger.
A rule indicating what processing / transition is performed for which input in each state is described in the processing / transition information.
Specifically, as shown in FIG. 55, a processing information list having the processing information described above as an element is included in the processing / transition information. The processing information includes a corresponding notification ID and a notification of the notification ID. When 101 is received, a control rule describing a transition destination state ID that becomes a state ID of a state to be transitioned and a control to be processed is described.

1.2.2. Description Method of Control Included in State Information Descriptions regarding rules and controls included in the state information described above may be described in a format that can be directly interpreted and executed by the information processing apparatus 100.
Further, the implementation related to control may be prepared in advance as a function on the information processing apparatus 100 side, and may be expressed by a function ID for identifying the function and a parameter list given to the function.
In addition, when the information processing apparatus 100 has a built-in interpretation / execution environment for an interpreted program language, the script code in a text format that can be interpreted by the execution environment and the execution environment can be interpreted. An intermediate language code may be used.

1.2.3. Specific Processing Example of State Control Unit Hereinafter, a processing example of the state control unit 101 will be described.

1.2.3.1. Example of Processing in Case of No State Transition A specific example of how the state control unit 101 performs processing based on the state information held will be described with reference to FIG.
In a specific example, it is assumed that the process is started with the input information notified by the user operating the input unit 107 as a trigger.
When the input unit 107 is operated by the user, the input unit 107 generates input information corresponding to the operation content and notifies the state control unit 101 of the input information.
The notified input information includes at least a notification ID for identifying an operation performed on the input unit 107.
Upon receiving the notification of the input information, the state control unit 101 has processing information having the value of the notification ID included in the notified input information in the processing list of the state information processing / transition information held at that time. A search is performed (S1901).
If there is no corresponding process information as a result of the search, the process ends.
If there is corresponding processing information, the control rule in the processing information is acquired (S1902), and control processing according to the acquired control rule is performed (S1903).
After that, when a state transition occurs along with the control process, the state transition generated along with the control process is given priority, so the state transition is performed using the transition destination state ID of the state transition generated along with the control process. Processing is performed (S1906).
When the state transition does not occur, the input information is notified to the focus control unit 103 (S1904), and a control processing command is issued to the focus control unit 103.
Also, state transition processing is performed (S1906) according to the transition destination state ID in the processing information (S1905).

1.2.3.2. Example of State Transition Processing with State Transition Next, an example of state transition processing performed when a state transition is accompanied will be described with reference to FIG.
In the above example, the state processing is performed when the state ID of the state information is different from the transition destination state ID.
In this case, the state control unit 101 acquires state information corresponding to the transition destination state ID from the data storage unit 106 in order to know what information the transition destination state is (S2001).
Process / transition information is acquired from the state information of the transition destination state (S2002), and after the transition, the state control unit 101 secures information used for control in advance, and then releases state information corresponding to the transition source state (S2003). The transition source state information is deleted from the state control unit 101, and the state control unit 101 starts to manage the transition destination state information and the processing / transition information therein as information to be processed.
Next, the display control information and the focus control information are acquired from the state information of the transition destination state, and the focus control unit 103 is notified together with the input information notified from the input unit 107 (S2004). The focus control information and display control information managed by the unit 102 are updated to the transition destination, and the focus control unit 103 and the display control unit 102 are initialized to the transition destination state and the display unit 108 transitions based on the information. The initial display of the previous state is performed (S2005 to S2008).
This completes the state transition process.

1.2.3.3. Specific Example of Control Processing Next, a specific example of control processing performed when a control rule is described in the processing information will be described with reference to FIG.
The state control unit 101 acquires a control rule in the processing information (S2201), and executes a process according to the control rule (S2202).
When the notification information to be notified by the state control unit 101 is included in the information passed as a result of the processing, the notification processing is performed on the notification destination described in the notification information (S2203). .
If information related to state transition is included in the information passed as a result of the processing, the control processing is terminated with the information (S2204), and the state transition is performed by the upper processing.
If the information regarding the state transition is not included, the control process is terminated without any information (S2205), the state transition is not performed in the upper process, and the normal process is resumed.

The processing example, the state transition processing example, and the control processing example of the state control unit 101 described above are merely examples, and it is not necessary to follow this processing method.
For example, notification information and state transition may not occur with the control process, and the state transition process and the release timing of the state information of the transition source may be changed.

1.3. Data Storage Unit The data storage unit 106 stores at least the state transition information required by the state control unit 101 and the data that may be necessary for the information processing apparatus 100 to perform processing. The information body is stored in the ROM 302, RAM 303, auxiliary storage device 306, etc. shown in FIG. 3, and the CPU 301 executes the management process.
In FIG. 1, the data storage unit 106 is stored inside the information processing apparatus 100, but does not need to be stored inside the information processing apparatus 100, and is installed outside and communicates with the external data storage unit 106. The communication means for storing the information may be stored in the information processing apparatus 100.
Regardless of whether the communication means is wired or wireless, the communication method is also the method of acquiring data from the data storage unit 106 installed remotely using Ethernet (registered trademark) or a mobile phone communication network, or the like (USB (Universal Serial Bus). The data storage unit 106 existing directly outside may be connected to the information processing apparatus to acquire data. Other storage media such as FDD (Flexible Disc Drive), CD (Compact Disc), DVD, Blu-Ray (registered trademark) Disk, etc. are used, the data itself is stored in the media, and is built in or connected to the information processing apparatus 100 The information processing apparatus 100 may use a method of accessing data by a media reading device, and these methods may be used alone or in combination.

1.4. Display Unit The display unit 108 is a final means for the information processing apparatus 100 to perform some display / output.
The display unit 108 is under the control of the display control unit 102 and uses the control from the display control unit 102 as a trigger to update the display content based on the control content and information specified by the display control unit 102.
The specific means for displaying is assumed to be a means for visually displaying text, images, videos, etc. using a CRT or a liquid crystal display, or a means for aurally displaying with sounds, etc. using a speaker or the like. . These may be used alone, a plurality of devices with the same means, or a plurality of devices with different means may be used.
Similarly to the data storage unit 106, the display unit 108 may not be built in the information processing apparatus 100, and the display unit 108 existing outside may be used.

1.5. Display Control Unit The display control unit 102 is a means for controlling what kind of display is specifically performed on the display unit 108.
Information regarding specific control is described in display control information notified from the state control unit 101 via the focus control unit 103.
The display control unit 102 includes display control information, processing results of the information processing apparatus 100 and data stored in the data storage unit 106, results of processing by the CPU, control of the focus control unit 103 described later, and display control unit 102. Based on the managed information, display information that can be interpreted by the display unit 108 is generated, and display control is performed on the display unit 108 together with the information.
The display control information is managed in the display control unit 102 until the next new display control information is notified, immediately before the next new display control information is notified from the focus control unit 103.
When new display control information is notified when there is already display control information in the display control unit 102, the display control information that has been managed so far is immediately discarded, and the newly notified display control information is displayed. Are newly managed and used for display control processing.
A specific update procedure of the display unit 108 will be described with reference to FIG.

For example, when the user operates the input unit 107, input information indicating the operation content is notified from the input unit 107 to the display control unit 102 via the state control unit 101 and the focus control unit 103.
The display control unit 102 notified of the input information acquires the notification ID described in the input information (S2301), and the display control information that the display control unit 102 holds the change rule corresponding to the notification ID. Is searched from the display change rule (S2302).
If the corresponding change rule does not exist as a result of the search, it means that it is not necessary to update the display according to the notified content, and thus the process ends at this point.
Conversely, if there is a corresponding change rule, it means that it is necessary to update the display content according to the notified content. Therefore, display content information that can be interpreted by the display unit 108 is generated according to the change rule. (S2303).
Display based on the individual change rule of the change rule acquired at that time, the object type common display rule of the display control information, the object information list, and the internal management information of the display control unit 102 held in the display control unit 102 Content information is generated (S2303), the generated display content information is notified to the display unit 108 (S2304), and the process is completed.
Although this example has been described as processing for user input, basically the same processing is performed on input information notified to the other display control unit 102 regardless of the type.

For example, in the information processing apparatus 100 that displays HTML content, when the user scrolls the screen by pressing the down button of the cross key, the display control unit 102 has input information having a notification ID corresponding to the short press of the down button. Is notified (S2301).
When a change rule is acquired according to the notification ID (S2302), for example, there is an individual change rule describing a change for scrolling the content down 10 pixels from the current screen display.
In accordance with this individual change rule, the display area information for the entire current content is acquired from the internal management information of the display control unit 102, and the position of the new display area is calculated by moving that area downward by 10 pixels throughout the entire content. Configure the display object information list, which is a list of object information contained in the area, from the object information list, and which objects to display in the area, together with the individual change rule and the object type common display rule Is generated (S2303), and the display unit 108 is notified (S2304).
In addition, a display target selection object information list obtained by extracting selection target objects from the display target object information list and generating a list is generated each time the display target object information list is generated (S2305). If they are different, a new display target selection object information list is notified to the focus control unit 103 as a response (S2306).
The display target selection object information list is used when the focus control unit 103 determines whether or not the object to be focused next is displayed on the display unit 108 based on the focus movement rule.

In the above description, scrolling is performed down by 10 pixels. However, the behavior is not limited to the number of pixels or scrolling, but is merely an example.
In addition, when generating the display content information, we explained that the display content information is generated using only the object after extracting the object included in the new display area. The display content information of the entire content may be generated and held in advance as internal management information of the control unit 102, and only the display content information included in the new display area may be extracted from the display content information. I do not care.

  Although display control related to focus is not performed in the above description, this processing will be described together with description of the focus control unit 103.

1.6. Input Unit The input unit 107 is a unit that receives a command for the information processing apparatus 100 from a user of the information processing apparatus 100, and the input unit 107 converts the input from the user into information that can be interpreted by the information processing apparatus 100. .
When the user operates the input device 305 in FIG. 3, the input unit 107 converts the operation into information by the input device 305, passes it to the CPU 301, interprets the information by the CPU 301, and interprets the interpretation result if necessary. Process based on.

1.7. Specific Example of Data Data to be processed by the information processing apparatus 100 is a representation of information to be processed when the information processing apparatus 100 performs processing, and is managed by an object information list in the display control information of the state information. Corresponding object.
For this reason, it can be said that the information is related to the object to be displayed on the display unit 108, but is not necessarily a specific target to be displayed and is an object that affects the control of the display control unit 102. It doesn't matter.

As a specific example, when the information processing apparatus 100 is a file system, a file or a folder that links files with a single name can be listed as data.
In addition to the minimum unit information (file) as in this file system example, data (folder) that can be decomposed into smaller units is handled as data.
In the case where the information processing apparatus 100 is a music playback apparatus, one piece of data represents music information to be played back, and normally, one file is formed for each song.
Music data can be classified by composer, performer, recorded album, recording date, date of announcement, etc. of the song. These superordinate concepts are called music data attributes, and attributes are also handled as data. . A folder in the file system described above can also be regarded as a superordinate attribute called a folder for a set of files.
When the information processing apparatus 100 is an HTML browser, the HTML file to be processed and its HTML file are analyzed, and the extracted tag, its attribute, text as a non-tag element, etc. are interpreted as data. I can do it.

1.8. Description of Data Selection Function The information processing apparatus 100 used in the description of the present embodiment is configured so that the user of the information processing apparatus 100 selects target data from all or part of the data stored in the data storage unit 106. It has a data selection function that makes it possible to select one or more.
When selecting a plurality of data, a method of directly selecting a plurality of data may be used, and one or more of the attribute information held by the data is selected from one or a plurality of contents, and the selected attribute information is held. You can select the data.

A basic processing procedure in the information processing apparatus 100 will be described with reference to FIG.
When the information processing apparatus is activated, it starts a boot process stored in the BIOS or the like, and activates a service application that the information processing apparatus 100 originally should provide to the user.
In the series of processing and processing related to the service application, when some data is transferred to necessary processing, if the information processing device 100 can further determine data to be processed, the information processing device 100 stores the data as data. Acquired from the unit 106 or the like and executes the process.
However, if the data to be processed has not been confirmed, if only a part has been confirmed, or if it has been confirmed but confirmation is required from the user, the above data selection function is used. Start up and prompt the user to confirm the data to be processed.
When the user selects and confirms data to be processed via the input unit 107 based on the contents displayed on the display unit 108, the information processing apparatus should process based on the input from the input unit 107 Confirm the data and continue processing based on the result.
Specifically, for example, in the case of a portable music playback device, the display unit 108 of the portable music playback device is used in order for the user to determine which of the music data stored in the data storage unit 106 should be played back. The music list is displayed, and the user is prompted to select a song to be played from the list. When the user selects a song, the portable music player reads the selected song data, Playback is possible.

  Next, specific display contents in the data selection function will be described with reference to FIGS. 4, 5, and 6.

An information processing apparatus 401 in FIG. 4 is a portable music playback apparatus.
The information processing apparatus 401 includes a liquid crystal display 402 as the display unit 108, and includes a determination button 403, a cancel button 404, and a cross key 405 as the input unit 107.
In the present embodiment, the following description is given on the assumption that the information processing apparatus 401 is used. However, the information processing apparatus need not be such an information processing device, and is provided with a numeric keypad, other function keys, and the like, and an operation using them. May be possible.
In addition, it does not need to be a music playback device, and has an input unit 107 and a display unit 108 such as a mobile phone, a car navigation system, a portable recording device and a personal computer, and the user selects data to be processed by the information processing device. As long as the information processing apparatus has a data selection function for realizing the instruction, it may take any form.

Next, FIG. 5 is an example of display information displayed on the liquid crystal display 402 while the information processing apparatus 401 is processing the data selection function.
This display information is a data selection display that prompts the user for music data to be played back by the information processing apparatus 401 based on the name of the performer or group that is playing the music.
In this display information, data such as a status display area 502 indicating the current state on the background image 501, data to be selected or the name of the data to be selected, a summary, an associated image, etc. are at least stored by the user. When the information displayed in the selection item display area 503 for displaying information that can be uniquely identified and the information displayed in the current selection item display area 503 are arranged based on a certain rule, which position is displayed on the arrangement list. A display area position display area 505 for displaying whether the image is displayed is drawn.

The status display area 502 displays information that allows the user to grasp what criteria the information processing apparatus 401 currently prompts the user to select data.
In FIG. 5, “Artists” is displayed, which indicates that the information processing apparatus 401 prompts the user to select music data to be played based on the name of the player or group performing the music. Yes.
In the selection item display area 503, the name, summary, associated image, etc. (hereinafter referred to as a thumbnail) of data to be selected by the current data selection function are displayed.
In FIG. 5, names of performers and organizations are adopted as thumbnails, and the names are displayed in an alphabetical order, for example, according to a certain rule.
When all the data to be selected cannot be displayed on one screen, the displayable number is displayed, and the display position display 506 displayed on the display area position display area 505 indicates which of the arranged data strings. Indicates whether the position is displayed.
When the display position display 506 is positioned at the top of the display area position display area 505, the data to be selected is higher than the top data displayed in the display area 503 in the alignment data list. If the display position display 506 is located at the bottom, meaning that it does not exist, the data to be selected exists below the lowest data displayed in the display area 503. It means not.
As described above, depending on the position in the display area position display area 505 where the display position display 506 is displayed, the user can determine which position in the alignment data list the data displayed in the selection item display area 503 is. It becomes possible to grasp intuitively whether there is.

  In addition, in the selection item display area 503, only the data to be selected or its thumbnail is not always displayed. In FIG. 5, the selection item displayed as “All” selects all the current selection target data. When selecting a data selection condition, canceling the execution of the currently selected data selection function, or making final data selection while narrowing down the data using the data selection function hierarchically, A thumbnail indicating the function for returning to the data selection function may be displayed.

Next, in the selection item display area 503, a focus 504 for displaying a thumbnail by distinguishing data to be selected from data not selected by the user performing a selection operation is displayed.
Since the focus 504 is different from other thumbnails in display, the focus 504 is usually different from other thumbnails by using display effects such as background, foreground, thumbnail highlighting and enlargement. It is possible to intuitively grasp which thumbnail the focus 504 is located on.

The selection operation is activated when the user presses the right button or the decision button for a short time in a situation where the data selection function is executed, and the thumbnail on which the focus 504 is displayed when the user presses the short button is used as the processing target data. Means to choose as.
If the current data selection function allows only one piece of data to be selected, when the selection operation is executed by the user, the data processing device immediately determines that the data is to be processed, and the information processing apparatus displays the thumbnail. The data corresponding to may be acquired from the data storage unit 106 and the process may be started.
In addition, when the selection operation is executed, a confirmation pop-up may be displayed on the display unit 108 to confirm that the data can be processed, and the user may be prompted to confirm the selection operation.
In addition, if the current data selection function allows a plurality of data to be selected, when the selection operation is executed by the user, in order to enable the user to recognize that the selected thumbnail has been selected, Emphasis is displayed using a method different from focus.
For example, it may be possible to display a background or foreground different from the focus or unselected thumbnail, or to display a check image on the left side of the thumbnail.
Similarly, if the selection operation is performed in a state where the focus is displayed on the selected thumbnail, the data corresponding to the thumbnail may be returned to the unselected state.
In addition, the corresponding data may be returned to the unselected state by short-pressing the cancel button while the focus is displayed on the selected thumbnail.
When the user finally wants to confirm the selection of data, when the determination button is pressed for a short time in any state, the information processing apparatus 401 determines that the data selection in the data selection function is confirmed, and the selected plurality It is conceivable to start processing using the data.

In FIG. 6, when the right button or the enter button is pressed for a short time in a situation where the focus is 504 on “Cob Sincler”, all the data related to “Cob Sincler” is selected, and the album released by “Cob Sincler” Move to the data selection screen to narrow down the data with.
Conversely, if the left button or the cancel button is pressed for a short time, the current data selection screen is interrupted, and if there is a higher data selection function of the interrupted data selection function, the upper data selection function returns to the upper data selection function. Transit to the screen for data selection processing again with the data selection function.
In FIG. 6, the screen shifts to a key selection screen for selecting a data narrowing key to be a higher-order data selection function of the data selection function by the performer, and a screen for selecting again which data is to be used for data selection is displayed. .

  In addition to the above example, the HTML content related to the displayed HTML content is displayed by focusing on the thumbnail indicating the related display to the other HTML content called an anchor in the displayed HTML content. When the HTML content is regarded as data, it can be said that the mechanism is realized by the data selection function.

1.9. Focus Move Procedure It is possible to change the data on which the focus 504 is displayed by the user's operation.
For example, when the user presses the down button 409 of the cross key 405 for a short time, the display of the focus 504 moves to the thumbnail of the data adjacent to the current focus 504 displayed on the display unit 108 on the lower side, and the cross When the upper button 408 of the key 405 is pressed for a short time, the display of the focus 504 moves to a thumbnail of data adjacent to the current focus 504 on the upper side.
In FIG. 5, the focus 504 is positioned at “Cob Sincler”. When the up button 408 is pressed for a short time in this state, the focus 504 moves to the adjacent “CCB World Service” on the upper side, and “Cob Sincler” is focused on the focus 504. Disappears (Figure 6-Down button short press).
Similarly, when the down button 409 is pressed for a short time when the focus 504 is positioned at the “Cob Sincler”, the focus 504 moves to the “Coom Com Satellites” adjacent to the lower side of the “Cob Sincler”. “Sincler” loses focus 504 (FIG. 6—Up button short press).
Further, when there is no adjacent data, focus movement is not performed.
For example, even when the up button is pressed while the focus 504 is positioned at “All”, there is no further selection item, and thus the focus does not move from the “All” position.
In addition, when the lower button 409 or the upper button 408 is pressed for a long time (continuously pressing the button), the focus 504 is continuously displayed on the lower side or on the upper side while the button is pressed for a long time. Repeat focus movement on thumbnail.
As in the case of the short press, the long press does not cause the focus to move when there is no selection item adjacent to the movement direction in the focus 504.
The focus movement by the long press usually moves the focus at a higher speed than the movement speed at the time of the focus movement by the short press so that the user does not feel stress even if the number of data to be selected is large.

At this time, since the focus movement is fast, it is difficult for the user to clearly recognize the thumbnail of which data the focus 504 is positioned during long press, and the user can Even if you try to stop the long press operation on a thumbnail, there is actually a problem that you are overrunning the target thumbnail, or conversely, you are stuck in front.
In this embodiment, even if the focus movement is performed at a high speed in the long press state, it is easy to recognize the thumbnail of the data frequently used by the user, and the focus movement can be completed with the thumbnail of the target data. The focus is on making it possible.

1.9.1 Difference in Handling of Selection Target Data and Non-Selection Target Data Data can be classified into the above-described selection target data that can be focused and non-selection target data that cannot be focused.
As described above, the data corresponds to the fact that the objects managed in the object information list in the display control information of the display information can be classified into selection target data and non-selection target data.

1.10. Importance Determining Unit, Importance Storage Unit Next, the importance of selection target data will be described.
The importance of the selection target data is information indicating how important the data is for the user. For example, how many times the user has selected the data in the past, the selection frequency, and the user The importance as a specific numerical value using indicators such as how many times the data has been selected in a certain past period, how often the data has been selected, and how relevant the data has been selected by the user in the past A calculation method is conceivable.
The importance level determination unit 104 provides a method for calculating the importance level, and the importance level storage unit 105 is a means for storing the calculated importance level and an index used for calculating the importance level for each data. is there.
Hereinafter, unless there is a need to distinguish clearly, an index and its value when calculating importance are also referred to as importance.
The importance level storage unit 105 cannot be managed only by the ROM because of the feature updated by the importance level determination unit 104, but the default value is managed by the ROM, and the latest information is stored by the RAM or the auxiliary storage device. There is also a way to do it.
Similarly, a method of storing only the RAM and the auxiliary storage device without using the ROM is also conceivable.

1.10.1. Example of Importance Based on Number of Selections For example, when the number of times a user has selected data in the past is used as an index, it is conceivable that the importance is calculated as the higher the number of selections, the higher the importance.
In this case, by providing a count data area for counting the number of times when the user performs a selection operation on the data, the data and the number of selections can be stored simultaneously.
As the data structure in this case, an area for directly storing the number of selections may be held for the data to be selected as shown in FIG. 14, and the data and the number of selections of the data may be stored as shown in FIG. Data may be associated with data that can be uniquely identified, and the number of selections and the data may be stored independently.

A method of using the reciprocal of the number of selections or an inversely proportional value as the importance may be considered.
The importance in this case is an importance that interprets that the data not selected by the user has a higher importance. For example, when using in a ToDo list, etc., this importance calculation method is not used. It is also possible to make items of higher importance.
In addition, even in the case of a new arrival information notification list display using RSS, it is appropriate to interpret that data that has not been selected by the user is new arrival information that has not been confirmed by the user yet and is highly important. It is thought that.

  Next, a specific update procedure when the past selection count is used as an index of importance will be described with reference to FIG.

When the user performs a data selection operation (S701), the information is notified from the input unit 107 to the focus control unit 103.
The focus control unit 103 detects that the data selection operation corresponding to the currently focused thumbnail is performed based on the information, and the data ID related to the focus target data managed in the focus control unit 103 The importance level update unit 104 is requested to update the importance level using as a key.
Upon receiving the importance update request, the importance determination unit 104 determines which data is to be updated based on the data ID (S702) given as a key, and acquires the number of selections for the data ( In step S703, the value obtained by adding 1 to the value is updated as the same data selection count (S704).
The importance update operation is completed by the above processing.
After that, the focus control unit 103 makes a data selection operation drawing request to the display control unit 102 (S705), changes the display content to the content corresponding to the data selection, and starts the state transition process that occurs with the data selection. (S706).

1.10.2. Example of importance based on the number of selections with a limited period A specific example of other importance is shown.
In particular, people may have different preferences depending on the season.
For example, music that is often viewed at the present time is often different from music that is often viewed a year ago.
Therefore, if the number of selections in the past is simply used as an index, it will not be selected at the present time, but both the data that was selected well in the past and the data that is often selected at the current time have the same number of selections In the case, it becomes the same importance.
For this reason, a certain period in the past is limited to, for example, half a year ago, and the number of times the user has selected in the limited period is used as an index of importance. The lost data can be filtered.
Also, a more flexible method of calculating importance by changing the weighting according to the elapsed time from the current time, instead of filtering at a certain date and time, can be considered.
In that case, by setting the weighting coefficient to a smaller value as the elapsed time from the current time increases, it is possible to obtain an effect similar to the case where the period is limited.

FIG. 16 shows a specific example of the data structure when the number of selections in a certain period is used as an importance index.
Since the number of selections past a certain date and time must be excluded from the calculation of importance, the selection date and time when the selection operation is performed on one piece of data is recorded instead of simply recording the number of selections. Each time a list is assigned, the date and time information at that time is added, and the selected date and time information that is older than a certain date and time is periodically deleted to prevent the explosion of the number of list elements.

  A specific update procedure for this data structure will be described with reference to FIG.

When the user performs a data selection operation (S1101), the information is notified from the input unit 107 to the focus control unit 103.
The focus control unit 103 detects that the data selection operation corresponding to the currently focused thumbnail is performed based on the information, and the data ID related to the focus target data managed in the focus control unit 103 The importance level update unit 104 is requested to update the importance level using as a key.
Upon receiving the importance update request, the importance determination unit 104 determines which data is to be updated based on the data ID (S1102) given as a key, and acquires a selection date / time list for the data. (S1103), current date information is added to the head of the list (S1104).
The importance update operation is completed by the above processing.
Thereafter, the date / time information stored in the list may be scanned, and the date / time information that has passed for a certain period may be deleted (S1105).
The deletion process is performed before the current date / time information is added to the selected date / time list, and if the date / time information to be deleted is in the list, the current date / time information is overwritten on the information to operate the data. You may reduce a procedure.
In addition, the focus control unit 103 issues a data selection operation drawing request to the display control unit 102 (S1106), changes the display content to the content corresponding to the data selection, and starts the state transition process that occurs with the data selection. (S1107).

In addition to the method of using the selection date / time list described above, a daily selection frequency list that counts the number of selections by date when the data is selected instead of the selection date / time in the data structure as shown in FIG. A method may be considered in which the date and the number of times of selection are managed in combination.
With this method, the number of list elements does not increase even if selected many times on the same day, and the memory consumption of the information processing apparatus can be suppressed. Even if the selection day is selected week or month, there is no essential difference.

  A specific update procedure for this data structure will be described with reference to FIG.

When the user performs a data selection operation (S1201), the information is notified from the input unit 107 to the focus control unit 103.
The focus control unit 103 detects that the data selection operation corresponding to the currently focused thumbnail is performed based on the information, and the data ID related to the focus target data managed in the focus control unit 103 The importance level update unit 104 is requested to update the importance level using as a key.
Upon receiving the importance update request, the importance determination unit 104 determines which data is to be updated based on the data ID (S1202) given as a key, acquires a list for the data, and obtains a list. Is searched for an element corresponding to the current date (S1203).
If there is no element corresponding to the current day as a result of the search, an element having the current day information and the number of selections of 1 is added to the list (S1204). If there is an element corresponding to the current day, the element is selected. 1 is added to the number of times (S1205).
The importance update operation is completed by the above processing.
Thereafter, the day information of the elements stored in the list may be scanned to delete the elements that have passed for a certain period (S1206).
In addition, the focus control unit 103 issues a data selection operation drawing request to the display control unit 102 (S1207), changes the display content to the content corresponding to the data selection, and activates the state transition process that occurs with the data selection. (S1208).

Specific importance calculation methods include, for example, a method of counting the number of date and time information that is newer than a certain date and time stored in the list corresponding to the data whose importance is to be calculated, and setting that value as the importance. By calculating the total of the result of multiplying the reciprocal of the value obtained by subtracting the date and time information newer than a certain date and time stored in the list from the current date and time information and the number of selections, the influence of the older date and time information on the importance is reduced. A method of weighting can be considered.
For example, weighting is performed as follows.

The above is an example of a specific importance calculation formula that performs weighting so that the older the date and time information is, the smaller the influence on the importance is.
The daily selection number list corresponding to the data d _i is expressed by SelectTime (d _i ), and the importance of the data d _i is expressed by Significance (d _i ).
For example, the date and time information can be expressed in terms of how many days have passed, with a certain date and time in the past as the reference date, and the week, month, hour, minute, second, millisecond, etc. Date information may be calculated as a unit. At this time, if a sufficient past date is set as the reference date, the date information becomes a positive value.
In the above example, only the reciprocal of the difference between the date and time information when the weighting of the number of selections is selected from the current date and time information is used, but a value obtained by multiplying the value may be used. If the reciprocal number is less than a certain value, the reciprocal number may be theoretically multiplied by 0 instead, and the weighting may be adjusted by omitting the calculation.

1.10.3. Importance using data attributes Specific examples of importance indicators other than the above are shown.
Much of the data is not an independent entity, but can find various relationships with each other.
For example, for music data, even if the music data is different, the performers performing the music are the same, the genres of the music are the same, or the recorded albums are the same. Or various relevance.
Therefore, even if the data has never been selected in the past, if it is strongly related to the data that has been selected in the past, the data that has not been selected is also highly important to the user. Interpretation is also possible.
Also, in the case of HTML content, word analysis is performed on a character string displayed as an anchor, and a word included in a frequently selected anchor is included, or a thesaurus related to the thesaurus such as a synonym or synonym of the word is included. An anchor that includes a vocabulary may be more important than an anchor that is not included.

As described above, the fact that there is commonality between different data using a certain matter (player, genre, word, etc.) as an intermediary is referred to below as data being related, and the matter that mediates the commonality is attributed I will say.
An attribute is a single attribute, and multiple values, for example, the name of the performer can be set with specific names of various performers. Normally, the attribute is assigned to the attribute name or attribute type (the attribute of the performer). Can be expressed by two values: an attribute name of the performer) and an attribute value that is the value (a specific name of the performer is an attribute value for the attribute of performer).
In addition, since the attribute itself can also be handled as data, it is possible to recursively assign an attribute to the attribute. An attribute having an attribute is called a higher attribute, and an attribute of a certain attribute is called a lower attribute. To.
For example, a player name attribute may be added to music data, and an album name attribute announced by the person may be added to the player name attribute.

A specific example of the data structure relating to the importance index using the attribute of the data will be described with reference to FIG.
Each data is composed of a data ID that is an identification number uniquely assigned to the data, an attribute data string having zero or more attribute data for storing attributes associated with the data, and a data body for storing the data itself. Is done.
For example, when there are a plurality of attribute types such as composer attributes and genre attributes for music data, the attribute data stores an attribute name data area for storing the attribute name and an attribute value of the attribute. It is conceivable to configure the attribute value data area.
In addition, when the attribute type associated with the data is single, for example, when only the vocabulary analyzed for the word with respect to the anchor in the HTML content is the attribute, the attribute name data area is omitted from the attribute data area, and the attribute value It is possible to express only in the data area.
In the present embodiment, in order to simplify the explanation, the attribute data string is assumed to have the same number of attribute data throughout all the data, but the number may be different for each data.
In this case, the number of attributes indicating the number of attribute data stored in the attribute data string is stored at the top of the attribute data string.

Also, an attribute-specific selection count list for recording the selection count of each attribute is prepared independently of the data.
This list is composed of an attribute data area in which the element indicates each attribute and a selection count data area that records how many times all the data associated with the attribute are selected, and the element is prepared for the total number of attributes. An arbitrary attribute has a one-to-one correspondence with an element in the list.
However, it is not always necessary to have a one-to-one correspondence. If all the data associated with the attribute has never been selected, the element corresponding to the attribute is classified by attribute. There is no problem even if the variable list method is not provided in the selection number list, and when an associated data is selected for the first time, an element associated with the number of selections of 1 is added to the attribute-specific selection number list.

When data is selected by the user using the data selection function, the number of selections by attribute is calculated by adding 1 to the number of selections of each element corresponding to all the attributes associated with the data from the list of selections by attribute. The list will be updated.
A specific update procedure for this data structure will be described with reference to FIG.

When a data selection operation is performed by the user (S1301), the information is notified from the input unit 107 to the focus control unit 103.
The focus control unit 103 detects that the data selection operation corresponding to the currently focused thumbnail is performed based on the information, and the data ID related to the focus target data managed in the focus control unit 103 The importance level update unit 104 is requested to update the importance level using as a key.
Upon receiving the importance update request, the importance determination unit 104 determines which data is to be updated based on the data ID (S1302) given as a key, and stores all attribute data held by the data. Obtained (S1303), 1 is added to the number of selections corresponding to all the attribute data held by the data in the attribute selection number table (S1305).
However, if the corresponding element does not exist in the attribute selection count table, the attribute is selected for the first time, so one element corresponding to the attribute data is added to the attribute selection count table (S1304). The number of selections is set to 1 (S1305).
The importance update operation is completed by the above processing.
Thereafter, the focus control unit 103 issues a data selection operation drawing request to the display control unit 102 (S1306), changes the display content to the content corresponding to the data selection, and activates the state transition process that occurs along with the data selection. (S1307).

  In order to calculate the importance in this example, for example, it is conceivable that the importance is determined by the sum of the number of selections corresponding to the calculated data attribute according to the following.

The above example is a calculation example of importance Significance (d _i ) of data d _i .
p (a _{k, i} , d _k ) is a weight for the number of times SelectTime (a _{k, i} ) of the attribute values a _{k, i} when calculating the importance of the data d _k .
By fixing all p (a _{k, i} , d _k ) to 1, the simple sum of the number of attribute selections becomes the importance.
These values may use fixed values as an information processing apparatus, but may use variable values.
For example, when certain data d _k is selected by the data selection function, the weight p ( _{ak, i} , d) corresponding to any attribute a _{k, i} belonging to the attribute set Attr (d _k ) corresponding to the data is selected. Variable values that increase _j ) are conceivable.
On the other hand, when a certain data d _k is selected, the weight p ( _{ak, i} , d _j ) corresponding to any attribute a _{k, i} not belonging to the attribute set Attr (d _k ) corresponding to the data is selected. A combination of a variable value that decreases the value and the above-described variable value that increases is conceivable.

In this example, the number of selections is set for each attribute, and the number of selections is adopted as the index of importance. However, the number of selections with a limited period may be adopted as the index of importance.
In this case, the selection frequency area in the element of the attribute-specific selection frequency list is replaced with a selection date / time list, a daily selection frequency list, or the like. Processing for the replaced data can be handled by diverting and applying the processing contents described in the explanation for the replaced data structure.

1.10.4. Next, the user explicitly inputs the importance. Next, there is a case where the user explicitly inputs the importance.
The information processing apparatus has an importance input function, and after the user selects data, for example, the index of importance is similarly aggregated on the PC that the user frequently uses, and the information processing according to this embodiment is performed. When the apparatus and the PC are connected, the importance index held on the PC side may be transferred to the information processing apparatus, and the information processing apparatus may perform processing using the transferred importance index.

Also, the specific examples described so far may be used in combination.
In addition to the specific examples described so far, another index indicating the importance of the data may be used, and the importance to be calculated is calculated by a simple addition method such as normalization. There may be variations such as.
In addition, the importance index is not necessarily generated and updated in the information processing apparatus according to the present embodiment, and the importance index is generated and updated in another information processing apparatus. You can use it.

1.11. Focus Control Unit Next, the focus control unit 103 will be described.
The focus control unit 103 is a means for controlling focus based on the input from the input unit 107 and the importance stored in the importance storage unit 105, and performs all focus management processing on the data selection screen. Control means to perform.
The focus control unit 103 manages the focus control information notified from the state control information in the focus control unit 103 until the next focus control information is notified, and performs focus control based on the information. .
In the focus control unit 103, the current display unit 108 holds a focused data ID which is information for managing which data corresponds to the data to be selected or information on which the focus is displayed on the thumbnail. To do.
Specifically, for example, an identification number and an identification value (identical path for a file, etc.) uniquely assigned corresponding to the data may be held, and the data itself may not be held.
The focus control unit 103 only manages which data or thumbnails the focus should be displayed on, and does not need to manage which position on the display unit 108 the focus should be displayed on. This is a display control unit 102.
In addition, the focus control unit 103 holds a display target selection object information list that is a list related to a selection target object among objects that are to be displayed on the display unit 108 by the display control unit 102.
This list is managed by the display control unit 102 updating the display target object and managing what is notified from the display control unit 102 every time the configuration of the selection target object is updated until the next notification is received. Maintained.
Using the display target object information list, the focus control unit 103 determines whether the object determined as the transition destination object based on the focus control information is an object that can actually undergo focus transition, and information regarding the transition destination object is the display target selection object. Judgment is made based on whether it is included in the information list. If it is included, it is determined that focus transition is possible, and if it is not included, it is determined that focus transition is impossible.

As shown in FIG. 8, the focus control unit 103 normally stands by in an input waiting state in which the input from the input device is intermittently checked (S801). When input information from the input device is detected (S802), it is determined what operation has been performed based on the information, and processing corresponding thereto is executed.
For example, in the case of the information processing apparatus 401 described with reference to FIG. 4, information for identifying which key is pressed is notified from the input unit 107. If there is, a determination process is executed (S803), if it is a cancel button or a left button, a cancel process is executed (S804), and if it is an up button or a down button, a focus movement process is executed.
At this time, if the button is an upper button or a lower button, it is determined whether or not the same button is continuously pressed. If it is determined that the button is continuously pressed, the process proceeds to a continuous focus movement process. While the user keeps pressing the same button, a process of continuously moving the focus in the same direction at a high speed is executed.
If it is not determined that continuous pressing has been performed, the process proceeds to a single focus movement process (S805).
As a determination method for continuous pressing, for example, there is a case where it is determined that continuous pressing is performed when the lower button or the upper button is continuously input a predetermined number of times without waiting for input.
In this embodiment, it is described that high-speed focus movement is activated by continuing to press the same button. However, in addition to this, the information processing apparatus is equipped with a dedicated button for high-speed focus movement, It may be activated by other means such as activated when the pressed input information is notified to the focus control unit 103.

When the process shifts to the continuous focus movement process, the focus control unit 103 acquires the importance level of the data corresponding to the selection item on which the focus is currently displayed from the importance level storage unit 105, and determines the selected item from the acquired importance level. Then, a focus maintaining time, which is a time for maintaining the focus, is determined (S806).
While the continuous focus movement process continues, the focus control unit 103 keeps the focus display for the currently focused selection item until the time determined here elapses, and the display control unit 102 Display requests are repeatedly performed while maintaining the focus.
Therefore, for the user, the focus maintaining time is recognized differently according to the importance of the data corresponding to each selection item during continuous focus movement.
When the time determined in the state where the continuous focus movement process is maintained elapses, the focus control unit 103 moves the focus display to data adjacent in the movement direction (S807), and stores the importance of the data at the movement destination as importance. The focus maintenance time for the data obtained from the unit 105 is calculated, and the same processing is repeated.

  By performing the above operation, the focus control unit 103 can change the time for maintaining the focus on the selected item according to the importance value, and which data is displayed to the user even during the high-speed focus movement process. It becomes possible to intuitively recognize whether it is important or not in the time when the focus is maintained.

  FIG. 25 is a specific example related to the single focus movement process (S805) in the case where the continuous pressing described in the above example is not performed.

In this process, it is determined whether or not a focus transition occurs for a short-pressed input, and input information is notified to the display control unit 102 together with the determination result.
First, a focus control description corresponding to the focused data ID managed by the focus control unit 103 is acquired from the focus control information (S2501), and an individual control rule corresponding to the notification ID of the input information is extracted from the focus control description (S2502). Further, a rule regarding short press is acquired from among them (S2503).
Since the focus transition rule is described in the rule relating to the short press, the transition destination object ID to be focused is determined according to the description (S2504).
It is searched whether or not the determined transition destination object ID is included in the display target selection object list. If it is included, the transition destination object ID is set as the focused data ID (S2505) and input to the display control unit 102. A display update request is made using the information and the transition destination object ID as parameters (S2507).
As a result of the search, if it is not included in the display target selection object list, a display update request is made to the display control unit 102 using the input information as a parameter (S2506).

  FIG. 24 shows a specific processing example performed by the focus control unit 103 at the time of continuous pressing (S806, S807) described in the above example.

When the focus control unit 103 determines that the button is continuously pressed, the focus control unit 103 determines whether the determination is the first determination or the second or subsequent determination.
In the case of the first determination, prior processing (S2401 to S2406) is required before performing the same processing as that performed in the second and subsequent determinations.
The pre-processing at the time of the first judgment will be described.
In this preliminary process, information necessary for the focus control process to be started is secured.
First, the current time is acquired, and that time is set as the long press start time (S2401).
Next, the importance corresponding to the focused data ID is acquired from the importance storage unit 105 (S2402).
Thereafter, a focus control description corresponding to the focused data ID is acquired from the focus control information (S2403), and the notification ID corresponding to the input information that is the cause of the current processing of the focus control unit 103 is handled. An individual control rule is acquired (S2404), and a rule relating to long press is acquired from among them (S2405).
This rule prescribes the behavior of the focus corresponding to the input that the user is operating the input unit 107 continuously at the present time.
Finally, the focus maintaining time, which is the time for maintaining the focus on the currently focused object, is determined from the rule and importance regarding the long press (S2406), and the pre-processing is completed.

Next, the process (S2407-S2413) at the time of the judgment after the 2nd time is demonstrated.
At the time of transition to this process, the long press start time, importance, and focus maintenance time necessary for the process are held in the focus control unit 103.
For this reason, in this process, it is determined whether or not the focus should be changed, and if the situation is to be changed, the focus transition process is performed.
The focus transition is determined by measuring from the long press start time and determining whether the focus maintenance time has elapsed.
Therefore,
When long press start time + focus maintenance time> current time is satisfied, that is, when the focus maintenance time has not elapsed, focus transition should not be performed. It can be judged that there is.
When it is determined that the focus transition should not be performed, a continuous press display update request is made to the display control unit 102 using the input information as a parameter to update the focus maintaining display (S2407).
Upon receiving this request, the display control unit 102 updates the focus maintenance display that does not involve focus transition.
This completes the process when no focus transition is involved.

Next, when it is determined that the focus should be changed, the focus control unit 103 needs to update the object to be focused and make a display update request in a state where the focus is changed.
In order to determine the focus transition destination object, the focus control description corresponding to the focused data ID is acquired (S2408), and the individual control rule corresponding to the notification ID of the input information is extracted therefrom (S2409). A rule is acquired (S2410).
Since the rule describes the focus transition rule for the currently pressed input, the object ID of the focus transition destination object is acquired based on the rule, and the value is set as the focused data ID (S2411). .
In addition, the long press start time, importance, and focus maintenance time for the focus transition destination object are recalculated (S2411), and information necessary for continuous press processing at the focus transition destination object is secured.
Finally, a continuous press display update request is made to the display control unit 102 using the input information and the focus data ID as parameters (S2413).
Upon receiving this request, the display control unit 102 updates the focus maintenance display with focus transition.
Thus, the process in the case of accompanying the focus transition ends.

Whether the button is pressed shortly or continuously, when the focus control unit 103 makes a request to the display control unit 102, a response is notified from the display control unit 102 to the focus control unit 103 as a result. The
In the response, when the configuration of the selection target object in the display target object is changed from the previous one as a result of updating the display content, the latest display target selection object list is stored and notified.
When the display target selection object information list is stored, the focus control unit 103 immediately replaces the display target selection object list managed by the focus control unit 103 with the notified list, and synchronizes the display contents with the list.

1.12. Focus Display Control in Display Control Unit Next, focus display control performed by the display control unit 102 will be described.
The requests that are received by the display control unit 102 and accompanied by focus display are a display update request and a continuous press display update request.
FIG. 26 is an example of focus display processing in the display control unit 102 when a display update request is made from the focus control unit 103.

In response to the display update request, the display control unit 102 updates the display content information in order to update the display content information (S2602), and generates new display content information. A display command is issued to the display unit 108 (S2603).
At that time, the display content information is generated by superimposing the focus display on the object to be focused.
For the information on the object to be focused, the display control unit 102 holds the latest transition destination object parameter ID or focus data ID notified as a request parameter from the focus control unit 103, and uses the value.
Therefore, when the transition destination object ID is included in the parameter included in the request, the focused data ID managed by the display control unit 102 is updated with the transition destination object ID (S2601).
Next, an object to be displayed is determined from the display control information and the input information, and display content information is generated. In the process of generating the display content information, when generating the display content information regarding the object that matches the focused data ID, the focus is set on the object based on the type common display rule or the object specific display information corresponding to the object. Overlay or change the display content of the object itself to generate the display content.
Finally, a display target selection object information list relating to the selection target object existing in the display target object information list is created (S2604), and when the configuration is different from the previously created configuration, the list is notified to the focus control unit 103 as a parameter ( S2605).
If the configuration is the same as the previous one, the notification of the list is not necessary, so normal completion is notified to the focus control unit 103 and the process ends (S2606).

  FIG. 28 is a focus display example when a button object is displayed when the display unit 108 is a display as a specific focus display example.

The display example of the non-focus button object is a button display example in a state where the button object is not focused.
On the other hand, the display example of the focus button object is a button display example when the button object is focused.
An example of frame emphasis is a display example in which the focus is superimposed on a button object frame with a thicker line than usual.
The color change is a display example in which the color of all or part of the button object is changed to a different color.
Color tone inversion is a display example in which the color tone of all or part of the button object is inverted.
The font size change and the font change are display examples in which the font size or type used when displaying the button name is changed.
The shape type change and the shape size change are display examples in which the shape type or size of the normal button display is changed.
Even in cases other than the display examples given here, it does not matter if the user can recognize that the display of the focused object is different from the display of the same type of object that is not focused. It may be blinking or zooming in on the focus target object.
A plurality of display methods may be combined.

  FIG. 27 is an example of focus control processing in the display control unit 102 when a continuous press display update request is made from the focus control unit 103.

Similarly to the display update request, the continuous press display update request can be divided into the case where the focus data ID is added to the parameter and the case where the focus data ID is added to the parameter. Pre-processing occurs before performing the same processing as when not attaching.
When the focused data ID is attached to the parameter, it is searched whether an object corresponding to the ID exists in the display target object.
If it exists, the focused data ID is substituted into the transition destination object ID and updated (S2702), and the focus target object is changed as notified.
If there is no object corresponding to the focused data ID as a result of the search, it means that the object for which the focus control unit 103 requests a transition is not a display target, and therefore the focused control unit 103 is a display target. The display area is updated as described above (S2701). Specifically, when the display unit 108 is a display, a method of translating the target object so as to enter the display area with a minimum movement distance from the position of the current display area, or a specific position of the target object in the display area (For example, the center of the display area) The display area is moved in parallel, the display area size is changed so that the target object can be entered, and the scale in the display control is changed so that the target object is entered. The method of doing etc. can be considered.
Thereafter, the focused data ID is substituted for the transition destination object ID (S2702), and the pre-processing ends.
By performing the above pre-processing, the focus movement destination by the normal short press was limited to the range of the display area determined by the display area, but the long press is not affected by the restriction and conversely the focus The display control unit 102 maintains the focus on a single object for the focus maintaining time, as a result of a reversal of the master-slave relationship in which the display control unit 102 determines the display area by being influenced by the focus target object determined by the control unit 103. The focus control unit 103 controls 102.

This processing is performed after the pre-processing or when the focused data ID does not exist in the parameter (S2703 to S2707). This processing is the same as the case of the display update request. The display rule acquired from the control information is different in that it is a rule when continuously pressed.
When the focused data ID is not attached to the parameter, the display control unit 102 maintains the current transition destination object ID, and the object display corresponding to the transition destination object ID is not out of the display range by the current update control. Performs update control as it is and generates display content information. When an object corresponding to the transition destination object ID is out of the display range, display content information is generated after adjusting the display area so that the object is within the display range.
The subsequent processing is the same as when the focused data ID is attached to the parameter.

  By realizing the functions described above, when a high-speed focus movement process occurs when the user continuously presses the input unit 107, the focus display is maintained according to the importance of the target selection target object. Therefore, the user can determine that an object with a higher focus maintenance time is a higher importance object.

  In addition, the focus maintenance time is determined for each data based on the importance for each data, and the state where each data is in focus is maintained during the focus maintenance time even during high-speed movement of the focus. Important data can be detected with certainty, and user convenience in data selection can be improved.

Embodiment 2. FIG.
2. Outline of Embodiment 2 The information processing apparatus according to the present embodiment changes the display method of focus according to the importance of the focused data.
For this reason, there is an effect that the user can intuitively grasp the level of importance by the difference in the display method of the focus.
Without this function, the screen update is stopped when the focus is on data with a certain level of importance or more. Therefore, the user may erroneously recognize that the screen cannot be updated due to a process failure. Therefore, when the focus comes to data with a certain level of importance, the screen update is stable by adding an animation effect to the focus to indicate that the screen is not hardened due to processing failure. This has the effect of avoiding user misrecognition.
In the present embodiment, only the focus display method is changed according to importance, and the display method of unfocused data is not changed.

Next, when a continuous press display update request is made from the focus control unit 103 to the display control unit 102, the importance level or focus maintenance time of the focused object is added as a parameter as a parameter, and the parameter is displayed by the display control unit 102 A specific method for controlling the display content of the focus by changing the focus display rule will be described.
In the following description, only the importance level is used as a parameter in order to briefly explain the contents. However, the importance level may be replaced with a focus maintenance time, and other parameters reflecting the importance level, for example, The number of selections of objects and related attributes may be used. Further, a plurality of parameters may be simultaneously notified from the focus control unit 103 to the display control unit 102, and the focus display rule may be changed by using them in combination.

2.1. First, a specific method for changing the focus display rule using the importance received from the focus control unit 103 by the display control unit 102 will be described.
As a method of changing the focus display rule, a method described in the individual change rule set for each notification ID included in the display control information of the state information can be considered.
For example, in each individual change rule, where a display rule is written when the focus is on, describe a conditional branch rule with a condition of importance further, and describe a different focus display rule for each branch destination. Thus, it is possible to incorporate a rule for changing the focus display rule according to the importance.
There is also a method of incorporating a conditional branch for directly changing the focus display rule into the display control unit 102 by a method other than the above, and it does not have to be incorporated in the display control information.

2.2. Examples of Conditional Branches for Changing Focus Display Rules Next, some specific examples of conditional branches used for changing the focus display rules will be described.
As the simplest conditional branching, there is a method in which one threshold is set for the importance, and conditional branching is performed when the importance is equal to or higher than the threshold and when the importance is lower than the threshold.
FIG. 29 is an example of conditional branching using a single threshold.
In this example, if the importance level is less than the threshold value, the focus color for the normal focus is set. If the importance level is equal to or higher than the threshold value, the focus color for the important focus is set to generate the focus display content.
Here, assuming that the importance is a value of 0 or more, and setting the threshold value to 0, the maximum value that can be taken as the importance, or a fixed value, the focus display rule is equivalent to a constant display control process.
The threshold value may be a fixed value or a value that can be changed according to the situation.
By changing the focus display rule in this way, the user can determine whether the focus of the object is more than a certain level based on the difference in color, and how long the focus is maintained. It is possible to intuitively grasp the importance of an object more quickly than recognizing whether or not it is.

FIG. 30 is an example of conditional branching using a plurality of threshold values.
Compared with the case where there is only one threshold, it is possible to classify the importance more finely, and it is possible to display the focus according to each, so the user can focus on the importance of the focused object in more detail There is an effect that it is possible to grasp intuitively by the difference in display.

29 and 30 show the branching method for classifying the importance into a finite number of sections according to the condition number. FIG. 31 shows a method of using the importance as a parameter of the focus display rule. This is an example of determining a focus display focus color using as a parameter.
Unlike the previous conditions, it can be classified into infinite categories.
Although it is possible to approximate even if the branch is using a segment, it is possible to approximate it by subdividing the segment sufficiently, but the load of conditional branch processing increases, so we want to change the focus display rule continuously according to the importance In some cases, using this branching method has the effect of reducing the processing load.

In the above explanation, the rule to be changed by changing the focus display rule is explained only by the color of the focus. However, it is not necessary to limit the color to the color. Even if other display rules are applied, such as switching external reference information such as used image files, the essential effects of the invention are the same.
In particular, the focus is maintained for an object with a certain degree of importance or more for a long time, and as a result, the content displayed on the display unit 108 remains the same during that period. There is a risk of misrecognizing that a processing failure has occurred due to processing exceeding the processing capacity of the apparatus. Therefore, when focus is maintained on an object of a certain importance level, the display content can be changed by updating the display content every time by turning on the animation effect in the focus display rule. It also has the effect of avoiding user misrecognition.

  Further, instead of changing one parameter of the focus display rule according to the importance as in the conditional branch of FIG. 32, it is also conceivable to change the parameter to be changed.

Embodiment 3 FIG.
3. Outline of Embodiment 3 The information processing apparatus according to the present embodiment displays the importance as a display target object other than the focus.
That is, in this embodiment, the importance received from the focus control unit 103 by the display control unit 102 is used for displays other than the focus display.
In the present embodiment, a message indicating that the focus has been extended is output, and the effect of avoiding misrecognition of processing failure and the importance are displayed as specific values, the number of objects, and graphs as more specific values. There is an effect that the user can grasp the importance.

3.1. Use as display contents of other objects Here, a method of using importance as a parameter when generating display contents information of an arbitrary object in a display target object list that is not in focus will be described as an example.

3.1.1. A status bar object that is permanently installed at the bottom of the screen is taken as an example here as a specific object that uses the importance displayed as a parameter when generating display content information.
The status bar is an object having substantially the same function as the state display area 502 in FIG.
FIG. 33 shows an example in which the display control unit 102 displays an image on the display which is the display unit 108 based on display control information having a status bar as an object.
The screen is divided into an area where thumbnails of data 1 to data 4 are arranged and an adjacent area below the area. The area where the thumbnails are arranged is a screen representing a data selection function, and the lower area is a status bar. It is an area.
It is assumed that the status bar can be displayed with any character string or image.
In this example, the data selection function is currently focused on the thumbnail data 2 and the status bar is a screen when the importance of data 2 is directly displayed as a character string.
Such display can be dealt with by describing the following display rules (1) to (3) in the object-specific display information of the object information corresponding to the object ID of the status bar.
(1) The importance level held by the display control unit 102 is converted into a character string.
(2) The result of (1) is concatenated backward to the character string “importance:”
(3) The result of (2) is displayed as the status bar foreground at the top.
By displaying as a specific numerical value as in this example, the user does not intuitively grasp the importance from the abstract importance expression such as the time for which the focus is maintained and the difference in the focus effect. There is an effect that can be recognized as a specific value.

  FIG. 34 shows an example in which characters and symbols corresponding to the importance value are displayed instead of directly displaying the importance on the status bar. In this example, the importance is classified into three levels, and is displayed as the second level when displayed as a character string of “Large”, “Medium”, and “Small” in order from the largest value. .

  FIG. 35 is a display example in which the number of symbols displayed on the status bar is changed according to the value of the importance level on the status bar. In this example, when the importance is classified into 6 levels and the number of symbols is displayed in order from the largest value to the 5th, 4th, 3rd, 2nd, 1st, or 0th, it is classified as the 4th stage. Is a display example.

FIG. 36 is an example in which importance is specifically shown by displaying the importance on the status bar in a graph instead of numerical values, characters and symbols.
When the graph is displayed, the longer the bar graph is, the higher the importance is displayed.
However, in the case of a certain degree of importance, all bar graphs may be displayed to the maximum, but when the maximum value of importance is notified together with the importance from the focus control unit 103, the maximum value is displayed. The bar graph length may be determined and displayed by dividing the importance by.

  When the importance of each object is displayed as a numerical value as shown in FIG. 33, it is difficult to grasp how high the value is as a whole, but the type of symbol displayed as in FIG. 34, FIG. 35, and FIG. By displaying the number and the length of the bar graph, the relative position can be grasped.

  Next, a display example for the status bar when other information related to the importance level can be acquired from the focus control unit 103 will be described.

FIG. 37 shows an example in which the rank and the total number are displayed when the total number of data and the importance rank of the currently focused object can be acquired from the focus control unit 103.
In this example, the fraction display is used, but a display using an image such as a bar graph as shown in FIG. 36 may be used.

  FIG. 38 is a display example when the maximum value and the minimum value of the importance level can be acquired from the focus control unit 103 together with the importance level.

  As described above, by acquiring information other than the importance level from the focus control unit 103, it is possible to easily grasp the relative position of the specific importance level.

3.1.2. FIG. 39 shows display contents displayed on the display, which is the display unit 108, by the display control unit 102 in accordance with the display control information related to the data selection function in which popup display is performed instead of the status bar.
Pop-ups are objects that have the same function as the status bar in that various information can be displayed in the foreground, but the status bar has a fixed display position, but the popup can change the display position according to the situation. Are different objects.
In this example, the display control unit 102 adjusts the position so that the tip part of the arrow part of the pop-up display overlaps the focused object, but does not overlap the other part. It is an example.
Therefore, if the focus moves from data 2 to data 3, the display control unit 102 temporarily determines the position of the pop-up and displays it at a position different from that in FIG.
The position calculation rule used at this time is described in the object-specific display information of the object information corresponding to this pop-up.
The display content is a bar graph, but other display content such as numerical display or symbol display of other importance levels may be used.

3.1.3. Changing the screen background color Besides that, it is also possible to change the background color according to the importance.

3.1.4. For example, in the case of an information processing apparatus that has a speaker in addition to a display as the display unit 108, for example, audio data that is associated with an importance value in advance according to the importance of an object that is in focus is used. It is also conceivable that the audio data is output from a speaker, and the output is performed in accordance with the importance by using a plurality of display units 108 in a composite manner.

Embodiment 4 FIG.
4). Outline of Embodiment 4 The information processing apparatus according to the present embodiment performs focus display control and display control of other objects using the remaining focus maintenance time for the focused object as a parameter.
In this embodiment, displaying the remaining focus maintenance time as a bar graph or the like has the effect of allowing the user to intuitively know how much focus movement will occur, and when the focus moves It is also possible to avoid making the user uneasy because he does not know.
In addition to the bar graph, it is also possible to change the focus animation behavior by using it as a parameter for determining the color and size of the focus and the change period thereof.
Further, since the display contents change every time because the control is performed with the remaining time, there is also an effect of avoiding erroneous recognition of processing failure.

In the present embodiment, another method for controlling the focus display displayed on the display control unit 102 according to parameters received from the focus control unit 103 will be described.
In the method according to the first to third embodiments, a parameter (for example, importance) received from the display control unit 102 or a value calculated using the parameter (for example, conditional branch processing using the importance is performed). Is the same value whenever it is obtained unless the importance of the object is changed.
Even if the importance of an object is not changed in the method described in this embodiment, a parameter whose value changes according to the situation or a value calculated using the parameter even if the received parameter is not changed Will describe a specific example in the case of using a value that changes according to the situation.
In the present embodiment, the display control unit 102 receives a continuous press display update request set with the remaining focus maintaining time as a parameter from the focus control unit 103 or a continuous press display update request set with the focus maintaining time as a parameter. A specific example will be described with reference to an example in which the display control unit 102 receives and calculates the remaining focus maintaining time.

Here, the remaining focus maintenance time is the time at which focus should be displayed on at least the object from the time when the remaining focus maintenance time is calculated for the object currently focused (the focus maintenance time Remaining time) or a parameter used to determine the time.
For example, the focus maintenance time is indirectly determined by expressing the remaining focus maintenance time in milliseconds as a specific time, or by giving the remaining focus maintenance time by the display content update count in the display unit 108. The case where it does is considered.
The focus control unit 103 does not move the focus on the currently focused object to another object, at least as long as the remaining focus maintaining time does not become zero while the continuous pressing display is continued.
Further, even if the remaining focus maintaining time is calculated when the focus time is exceeded, it is treated as 0 and does not become a negative value.

4.1. Displaying the focus as a bar graph Here, the control for changing the size of the focus display using the remaining focus maintaining time will be described.

FIG. 40 specifically shows an example of a method for determining the size when the size of the focus display is changed using the remaining focus maintaining time.
In this figure, when the data 2 and the data to be displayed as thumbnails are the focus target, the focus height is fixed and the width is controlled by using the remaining focus maintaining time (represented as the remaining time in the figure). Control is in progress.
If the width in the normal focus display is W, the focus maintenance time is T _focus , and the current focus maintenance time is t, the width W _f (t) from the left end of the focus displayed in this example is Calculated by the formula.

As shown in FIG. 41, in the initial display in which the focus maintaining time and the remaining focus maintaining time coincide with each other, the focus width is 0, and the remaining focus maintaining time is reduced every time display is repeated. In the state where the remaining focus maintaining time becomes zero, the display in which the focus width becomes equal to the width W of the normal focus display is performed.
FIG. 42 shows a state in which the thumbnail of data 2 in FIG. 41 is displayed together with other thumbnails. In the thumbnail of the data 2 in FIG. 42, as shown in FIG. 41, the width W of the focus display increases with time.

Conventionally, the specific display rule of the focus is a process in which a fixed expression is performed according to the rule described as part of the display control information of the state information. In this method, the focus width W _f (t) is This can be dealt with by changing the description of the specific display rule of focus so that focus display is performed using the value calculated from the remaining focus maintenance time.
By applying this display method, the focus display will be recognized like a bar graph animation extending from the left end to the right end, and the animation speed will be the value obtained by subtracting the remaining focus maintenance time from the focus maintenance time. Since the value divided by the maintenance time is determined as a parameter, the animation speed becomes slower as the focus maintenance time is longer, in other words, the focus display for the object having higher importance.

As described above, by controlling the focus display using the remaining focus maintaining time as a parameter, the user can recognize the focus display as a bar graph of the focus elapsed time, and the object is displayed until the focus display reaches the right end. It is possible to intuitively recognize that the focus is maintained.
Therefore, information indicating how much focus is maintained for the object, which is difficult to recognize with the focus display as shown in the first to third embodiments, can be visually provided to the user. effective.
In addition, instead of displaying the focus maintenance time in a separate area from the focus, the remaining focus maintenance time is presented by controlling the display of the focus where the user is most focused. Does not reduce the visual fatigue of the user.
Furthermore, since an object with higher importance has a slower focus animation display speed, there is an effect that the user can intuitively recognize the approximate importance from the animation display speed of the focus display.

4.1.1. Similar expression method In the above explanation, the focus display is controlled by determining the width from the left end of the focus by the remaining focus maintaining time, but the focus display parameter to be controlled is fixed to the width from the left end. The height from the bottom may be controlled by the remaining focus maintaining time, or the width from the right end may be controlled.
In addition, it is possible to control other parameters instead of controlling the size of the focus display. Specifically, the focus color, reduction / enlargement ratio, deformation ratio, display period of the focus display animation, etc. It is done.

4.1.2. An expression method similar to a pie chart As shown in FIG. 45, a display method such as a pie chart is conceivable instead of a display method such as a bar chart. In this case, the range in which focus display is performed from the center point of the normal focus display and the reference line is determined by the following angle θ _f (t).

4.1.3. Expression Method for Controlling Focus Color When controlling the focus color, if a value from 0 to 1 is given as shown in FIG. 43, a continuous color between a certain start color C _{start and a} certain end color C _end Using the function f _color (x) that returns, the focus color C _focus at that time is obtained by the following equation that is determined using the remaining focus maintaining time t as a parameter.

The function f _color (x) is C _start ≦ f _color (x) <f _color (x + ε) ≦ C if 0 ≦ x <x + ε ≦ 1 holds for ∀x and ∀ε∈ [0,1]. _It is desirable that _end is established, and by satisfying this condition, it becomes possible to operate the focus display as a continuous color change with respect to the change in the remaining focus maintaining time as shown in FIG. It becomes easier to recognize the change until the focus color is displayed with the end color C _end , and it is possible to intuitively recognize the approximate value of the remaining focus maintenance time from the current color.
FIG. 44 shows a specific display example by a method in which C _start is white, C _end is black, and two composite colors are controlled as the focus color. The composite color indicates the color composition ratio (T _focus −t) / The method of determining by T _focus is taken.
By controlling the color change like this, the closer the focus color is to black, the shorter the time that the focus is maintained, and the faster the focus color changes from white to black, the more important It means that the degree is low.
In FIG. 44, the display of the thumbnail display data 2 is initially performed in black. However, as the focus color approaches black, the thumbnail display color becomes the same as the display color of the thumbnail. The display color may be controlled to be a complementary color of the focus color.

4.1.4. Expression method for controlling the animation cycle In addition, the display cycle of the focus display animation can be made intuitively by changing the animation cycle by shortening the animation cycle as the remaining focus maintenance time disappears, or by changing it slowly. It becomes possible to grasp.

4.1.5. Expression method other than display The method of controlling the focus display using the remaining focus maintaining time as a parameter as described above is a specific example in the case of having a display as the display unit 108, but other display units 108 such as speakers are also displayed. When the display unit 108 is used as the unit 108, the display may be controlled using the remaining focus maintaining time as a parameter even when the focus display is performed from the speaker.
For example, when SE (Sound Effect) is displayed from a speaker while the focus is maintained for a certain object, a method of controlling the SE frequency according to the remaining focus maintaining time can be considered.
By controlling the SE frequency to be shorter as the remaining focus maintaining time is shorter, the user can intuitively recognize the remaining focus maintaining time according to the pitch.

Embodiment 5 FIG.
5. Specific Example on Screen Fixed Type Data Selection Screen In this embodiment, a specific data selection function will be described as an example.
Here, a data selection screen in which selection items as shown in FIG. 9 are displayed in a two-dimensional array format will be taken as a specific example of a screen selection type data selection screen without scrolling.
In this screen, the selection items data1 to data25 are displayed on the array, indicating that the focus is displayed on the data 25 surrounded by a thick frame.
When the data selection screen is operated by an information processing apparatus having a cross key and a determination / cancel key as shown in FIG. The corresponding data is selected, and the current data selection screen is interrupted with the cancel button.
When the left button is pressed while the data displayed at the left end is in focus, the focus moves to the data at the right end one step below the line in which the focused data is arranged.
Conversely, when the right button is pressed while the data displayed at the right end is in focus, the data moves to the left end data one level higher.
Similarly, when the upper button is pressed while the uppermost data is in focus, the focus moves to the lowermost data on the left side of the line where the focused data is arranged, and conversely, the lowermost data is in focus. When the down button is pressed, the focus moves to the uppermost data on the right.

In this screen example, only up to 25 data selection items can be displayed.
Therefore, when there is more data, when the right button is pressed while the focus is displayed on the selection item of data 25, the focus control unit 103 notifies the display control unit 102 of input information.
Upon receiving the notification, the display control apparatus updates the display content on the content screen shown in FIG. 10, and data from data 26 to data 50 is displayed as selection items.
At that time, the display control device displays the focus on the data 26.
Control related to the focus display is described in the display control description.
Finally, a new display target selection object information list is generated, the list is notified to the focus control unit 103, the display target selection object information list of the focus control unit 103 is updated, and the focus target object ID is set to data26. Update.
Conversely, by pressing the left button of the cross key while the focus is displayed on the data 26, the focus control device notifies the display control unit 102 that the focus has moved to the data 25. Upon receiving the notification, the display control apparatus updates the display contents on the screen having the contents shown in FIG. 9, and data from data 1 to data 25 is displayed as selection items. At that time, the display control device displays the focus on the data 25 that should display the focus notified from the focus control device.
When the focus shifts to data that cannot be displayed on such a screen, a data selection function screen that updates all displayed contents is referred to as a screen fixed data selection screen.

In this case, if you press and hold an arbitrary direction button and high-speed movement of the focus starts, the focus is displayed for all objects with a uniform focus maintenance time, and after that time, it moves to the next object. Although it was a prior art, since the focus maintenance time becomes longer in proportion to the importance by applying the control shown in the first to fourth embodiments, the object for which the user keeps the focus long is important. It is possible to judge intuitively when the degree is high.
Also, by controlling the focus display using the focus maintenance time and the remaining focus maintenance time, the importance of the focused object and the remaining focus maintenance time until the current focus moves to the next object are displayed. By this, the effect that enables the user to grasp intuitively is obtained.

  In this way, in the case of a screen fixed type data selection screen that does not involve scrolling, Patent Document 1 cannot cope with it because the scroll amount has to be adjusted. However, in the control shown in the first to fourth embodiments, the selection item is selected. Since the focus maintenance time is controlled, it can be dealt with regardless of the presence or absence of scrolling, and the importance of the data corresponding to the selected item can be presented to the user during the focus maintenance time.

6). Specific Example on Scroll Type Data Selection Screen Next, the data selection screen in the case of scrolling as shown in FIG. 5 will be described as an example.
In this screen example, data to be selected are arranged as a list based on a rule in a vertical column, and a part of the list is displayed on a display which is the display unit 108.
Normally, in such a display method, when the user presses the down button, the focus moves to the data aligned next to the currently focused object, and when the up button is pressed, the current focus The focus is moved to the data aligned in front of the object being placed.
However, if the user presses the down button when the focus is on the bottom data displayed on the screen, the second data is displayed at the top of the list, and the third data is displayed at the second. The display contents are shifted up one level, such as by displaying the data of, and the data arranged next to the data displayed at the bottom is displayed at the bottom, and the data on the display is scrolled. It is possible to display all the data in the list on the screen by giving the effect of displaying to and performing this operation intermittently.
Similarly, if the user presses the up button when the focus is on the top row, the display content is shifted in the direction to display the previous data on the bottom row, contrary to the case where the top button is pressed. Respond with things.

If you perform high-speed focus movement on a data selection screen that involves scrolling, you can usually scroll all the data faster by making the scrolling speed faster than if you normally pressed the upper or lower button continuously. A method for shortening the display time can be considered.
In this case, in the methods of the first to fourth embodiments in which the focus maintaining time is controlled according to the importance level, depending on the length of the focus maintaining time, the focus is maintained unless the scroll speed performed during the high-speed focus movement is changed. In some cases, the displayed data is not displayed on the display unit 108.
In order to avoid such inconveniences in display, a method of stopping the scroll speed or switching to a low speed may be considered when focus display is performed on data having a certain focus maintenance time.
For example, there is a method of switching the scroll speed between a low speed and a high speed when the focus is on data with a certain focus maintenance time or more and when the focus is on data with a focus maintenance time less than a certain time.

6.1. Scroll Speed Determination Method Using Importance Level An example of a specific scroll speed determination method other than the above will be described with reference to FIG.
Assume that in the situation where the high-speed focus movement display is currently performed in the upward direction, the focus has moved to the data D _cosincler corresponding to the thumbnail “Cob Sincler” for the first time. At this time, when the distance between the upper side of the thumbnail “Cob Sincler” and the upper side of the list display area is represented by a movable length h, and the focus maintenance time of the data corresponding to the thumbnail “Cob Sincler” is T _focus (D _{cobsin cler} ), The scroll speed S (D _cobsincler ) for the scroll direction is determined by the following equation.

  Thereby, it is possible to avoid moving the thumbnail display of the data to be focused outside the display area. In this method, when the scroll direction is reversed, the movable length can be similarly processed as the distance from the lower side of the focus to the lower side of the list display area.

6.2. A method for determining the scrolling speed based on the focus display position There is a method for determining the scrolling speed depending on which position in the list display area the focus is displayed on.
FIG. 47 illustrates a method of determining the scroll speed according to the focus display position in the list display area.
When the scroll method is in the upward direction, the scroll speed is uniquely determined as shown in the graph on the right side of the figure depending on which position between (1) and (10) the focus display is.
When scrolling is in the upward direction, if the focus display is in the position (1), the scroll speed is set to 0, and further scrolling causes the data to be focused to scroll out of the display area. To avoid.
Each time the focus display position moves below the list display area (1), (2), (3)..., The scroll speed is set faster.

By determining the scroll speed as described above, when low-importance data is continuous, the focus display is displayed at the bottom of the list display area, and scrolling is performed at high speed, so that high-importance data is displayed. Then, since the focus is maintained, the focus display position moves to the upper part of the list display area, and accordingly, the scroll speed can be controlled to be low.
In this method, when the scroll direction is reversed, the relationship between the position and the speed is also reversed as shown in FIG. 48. In (10), the scroll speed is 0, and the scroll speed increases as it approaches (1). become.
This method is different from the scroll speed determination method described above in that the display control unit 102 can determine without using the importance level without knowing the scroll speed, the focus maintaining time, and the remaining focus maintaining time.

Although the method of determining the scrolling speed based on the focus display position has been described as a method of determining the speed based on a discrete positional relationship in order to simplify the explanation, it is not necessary to be discrete, and the position expressed by continuous values. You may calculate using a relationship.
Also, the scroll speed need not be proportional to the focus position relationship, and it does not matter if the acceleration varies depending on the position, such as a quadratic curve or logarithmic function, but the focus display that is the purpose of speed control is displayed in the display area. In consideration of the fact that it is not moved outside, it is desirable that the speed be zero when the focus is displayed in the display area positioned most in the scroll direction.

  As described above, even in a data selection screen that involves scrolling, by controlling the scroll speed as described above, it is possible to avoid the focus display from moving outside the display area by maintaining the focus. 9 can be regarded as substantially equivalent to the screen fixed type data selection screen described with reference to FIG. 9, and the same effect can be obtained.

1.7. Specific Example in Web Browser Next, the scrolling is not limited to one axis, and HTML content display in a Web browser in which the display order of the selection target objects does not match the screen display order is taken as an example. The application example of the system of the form 1-4 is shown.
A Web browser is an application that displays an HTML document on a screen using an HTML document and related data from an arbitrary server via the Internet.
The HTML document can be used to lay out the display result of the HTML document in an arbitrary size for use. Usually, not only the scroll in the vertical direction but also the screen display that can be scrolled in the horizontal direction at the same time.

FIG. 49 is a diagram illustrating a state in which a screen area that can be displayed on the display, which is the display unit 108 of the information processing apparatus to which the methods of Embodiments 1 to 4 are applied to the entire view of an HTML document, is surrounded by a broken-line rectangle.
Since the HTML document is larger in both the vertical and horizontal directions than the area that can be displayed by the display unit 108 as in this example, when this HTML document is displayed on the display unit 108, only a part of the area is displayed. For example, a specific example in which a broken line area is displayed is as shown in FIG. 50. In general, not only a vertical scroll bar but also a horizontal scroll bar is displayed.
An HTML document has a part called an anchor for associating with another HTML document and the like, and the Web browser handles the anchor as one of the focus targets.
In addition to the anchor, an object that can be operated by a Web browser user of a form object such as a button or text is set as a focus target.
Therefore, when the methods of Embodiments 1 to 4 are applied to a Web browser, the Web browser treats the type of object to be focused as a selection target object, and is not pasted on any other document, anchor, or form object. Data such as images are handled as non-selected objects.
Since an image can be pasted on a selection target object such as an anchor, the image may appear to be focused when displayed on the display unit 108.
FIG. 50 shows a situation where the image displayed as “J” in the upper left is focused, but this is not focused on the image itself, but this image is pasted. Interpret that the anchor is in focus.
Next, the focus movement of the HTML document may be moved to the closest selectable object when the HTML document is displayed on the display unit 108, or may be moved in the order of appearance in the data of the HTML document.
In the HTML document, the positional relationship on the display of the object does not necessarily match the appearance order on the data.
For this reason, when high-speed focus movement is performed, the high-speed focus movement displayed on the display unit 108 moves, for example, from the anchor at the bottom of the whole content view to the anchor at the top of the whole content view independently of the display position. In some cases.
For this reason, the method of controlling the scroll amount as described in Patent Document 1 cannot be used.
However, in the case of the method shown in the first to fourth embodiments, even if the web browser has scrolling with respect to two axes, if the scroll speed control described above is made to correspond to each axis, data selection of a substantial screen switching type is possible. It can be handled in the same way as a screen, and in the case of discontinuous focus movement, the problem is that the order of appearance in the data and the appearance position relationship on the display are independent and focus movement does not result in continuous screen movement. Can be regarded as screen switching of a screen switching type data selection screen, and the methods shown in Embodiments 1 to 4 can be applied.

Unlike an ordinary data selection function, an HTML document is not applied to a substantially fixed data set, but handles a huge amount of data updated every day on the Internet as a selection target. Therefore, it is assumed that the effect of the present invention is not effectively exhibited when an unknown HTML document is displayed only by the method of obtaining the importance only by the number of selections for each anchor.
When such arbitrarily updated data is selected as the selection target, the importance shown in the first to fourth embodiments is not limited to the number of selections of the selection target but is important using the selection target attribute. By applying the degree calculation method together, it is possible to determine the degree of importance based on the degree of coincidence and similarity with an anchor attribute selected in the past even in an unknown HTML document.
For example, if a character string displayed as an anchor of HTML content is lexically analyzed and a word is added to the anchor as one attribute, for example, an anchor that often includes the word “soccer” or “soccer” For a user who selects an anchor that includes the word ”, an anchor that includes“ soccer ”as a word in an unknown HTML document or an anchor that includes the word“ soccer ”within a certain range Assuming that the importance is higher than other anchors that are not included, it is possible to set a longer focus maintenance time than other anchors during continuous focus movement.
Here, the fixed range may be a method of designating the range before and after the anchor tag corresponding to the target anchor by the number of characters, but a method of designating by the number of generations of the parent-child relationship of the tag is also conceivable.

For example, FIG. 52 shows a display content example when the HTML document shown in FIG. 51 is displayed on a Web browser. At this time, when the anchor and up to 5 characters before and after it are targeted for lexical analysis, in the case of a user who often selects an anchor associated with the “soccer” attribute, the first anchor displayed as “soccer”, and The anchor “baseball” displayed immediately after the anchor is associated with “soccer”. On the other hand, the anchor “Judo” has “Ker Baseball” in the first five characters and “Newest Ad” in the last five characters, and is not associated with soccer, and the importance is not raised.
Similarly, the last “sports ○ △ ×” is an anchor related to soccer as judged from the content of the advertisement, but the word “soccer” is not included in the anchor and the five characters before and after it, so as with other anchors The importance remains the same. Therefore, in this case, the anchors “soccer” and “baseball” are determined to be more important than the other anchors.

Next, consider the case where the analysis range is the same content, for example, up to two generations of tag parent-child generations.
In this case, since the anchor “baseball” and the anchor “judo” exist in the same generation as the anchor “soccer”, it is determined that these three types of anchors have high importance.
In addition, because there is a character string “If it is the latest soccer shoes” that exists in the first generation of “Sports ○ △ ×” on the HTML document, the result of lexical analysis is included in “Sports ○ △ ×” Similarly, it is determined that the importance is high.
Therefore, in this case, when the importance of the anchor is determined by the attribute “soccer”, it can be understood that all the anchors have the same importance.
In order to obtain the importance level in more detail, other methods can be considered, or a method can be considered in which the importance level is differentiated in consideration of the distance depending on the number of characters included between the attribute and the anchor.

  For anchors to which images are pasted, characters such as a method of recognizing characters in the image and using the word as an attribute, or an alt attribute of an anchor tag corresponding to the anchor in an HTML document It is possible to perform the same treatment as an anchor displayed as a character string by analyzing a string and using a method of treating a word as an attribute in the same manner.
