Description

  The present invention relates to an information display device, an information display method, and a program.

  There is an information display device that facilitates searching for information desired by a user from a plurality of pieces of information. This information display device lists and displays a plurality of items on a display screen. The user browses and selects items listed on the display screen. At this time, when an item including desired information is not found on the display screen, the user scrolls the list display to display an item that has not been displayed so far. By scrolling in this way, the user can browse all items (see Patent Document 1).

  In such an information display device, input devices such as a trackball and a wheel are used to simplify a user's scrolling operation. See Patent Document 2 for the trackball. FIG. 8 is a diagram showing the trackball 30. FIG. 9 is a diagram showing the wheel 40. In the trackball 30 shown in FIG. 8, when the user turns the trackball 30 in any direction, front, back, left, and right, the cursor moves in any direction, up, down, left, or right on the items listed on the display screen. In the wheel 40 shown in FIG. 9, the user moves the cursor in any direction up or down on the items listed on the display screen when the user turns the wheel 40 in any direction. In the case of the wheel 40, the cursor can also be moved up, down, left, and right by moving the mouse 41 on which the wheel 40 is installed from front to back and from side to side.

  Furthermore, when the cursor tries to move out of the display screen, scrolling of the display is started. At this time, the scrolling speed can be varied according to the rotational speed of the trackball 30 or the wheel 40. That is, when the user browses items listed on the display screen and finds that the item including the information desired by the user is in a completely different place on the list, the user can quickly switch the list display. For this reason, the user moves the trackball 30 or the wheel 40 at high speed. The information display device varies the scrolling speed following the user's operation. The scrolling speed (scrolling speed) is the number of information scrolled per unit time (that is, the number of items displayed for each row or column). Patent Document 3 discloses an information display device that controls the scroll speed by key operation instead of the trackball 30 and the wheel 40.

Japanese Patent Laid-Open No. 7-334145 JP 2002-169655 A JP 2007-94974 A

  As described above, in the conventional information display device, the scrolling speed can be varied according to the user's operation. However, during the high-speed scrolling, it is difficult to read necessary information from the items on the display screen because the moving speed of the items displayed on the display screen is fast.

  In particular, when the information display size is large, the number of information items simultaneously displayed on the display screen is smaller than when the information display size is small. The scroll speed is an enumerated number of information scrolled per unit time. Therefore, when scrolling at the same scrolling speed in a state where the number of information items displayed simultaneously on the display screen is small and a large number, the state where the number of information items is small is larger than the state where the number of information items is large. The movement speed of the item becomes faster. Accordingly, when the information display size is large and the high-speed scrolling is performed, it is almost impossible to read the information. On the other hand, if the information display size is reduced, it becomes difficult to read the information when not scrolling or when scrolling at low speed.

  The present invention has been performed under such a background, and provides an information display device, an information display method, and a program that allow a user to easily read information even during high-speed scrolling in addition to when not scrolling or during low-speed scrolling. The purpose is to do.

  The information display device of the present invention includes a display means for displaying information, an operation means for scrolling the information displayed by the display means so that the scroll speed can be varied, and a scroll speed by the operation means is greater than or equal to a predetermined value. Control means for reducing the size of the information displayed on the display means and increasing the number of items displayed on the display means when the speed exceeds the scroll speed less than the predetermined value or less than the predetermined value; It is characterized by having.

  At this time, the control means can reduce the size of the character displayed on the display means when the scroll speed is increased. Alternatively, the control means can reduce the size of the image displayed on the display means when the scroll speed increases.

  Further, when the operation means can issue a scroll instruction in all directions on the scroll surface of the information displayed on the display means, the control means performs scroll display by the display means among the scroll instruction directions on the operation means. The scroll speed can be determined based on the speed component in the possible direction.

  The present invention can also be viewed from the viewpoint of an information display method. That is, the information display method of the present invention includes a display step for displaying information, an operation step for scrolling the information displayed by the display step so that the scroll speed can be varied, and the scroll speed by the operation step is a predetermined value or more. When the value exceeds the predetermined value, the size of the information displayed in the display step is reduced and the number of items displayed in the display step is increased compared to when the scroll speed is less than the predetermined value or less than the predetermined value. And a control step.

  The present invention can also be viewed from the viewpoint of a program. That is, the program of the present invention is installed in an information processing apparatus, and as a function of an information display apparatus realized in the information processing apparatus, a display function for displaying information and scrolling information displayed by the display function An operation function that allows variable speed scrolling, and when the scroll speed by the operation function exceeds or exceeds a specified value, it is displayed on the display function compared to when the scroll speed is less than or less than a specified value. And a control function for reducing the size of information to be displayed and increasing the number of items listed in the display function.

  According to the present invention, it is possible to realize an information display device in which a user can easily read information even during high-speed scrolling.

  The configuration of the information display device 20 according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block configuration diagram of an information display device 20 according to an embodiment of the present invention. As shown in FIG. 1, the information display device 20 includes a storage unit 1 that stores information to be displayed, a display unit 2 that is a display unit that displays information, and a list display control unit that is a part of the control unit 10. 3.

  The list display control unit 3 is a list display unit that enumerates a plurality of items including information stored in the storage unit 1 and displays them on the display unit 2. That is, the list display control unit 3 takes in information stored in the storage unit 1, generates information arranged as a plurality of items, and displays the information on the display unit 2. For example, the list display control unit 3 extracts only information including the keyword specified by the user from the information stored in the storage unit 1, arranges it as a plurality of items, and displays the information on the display unit 2. Or the list display control part 3 rearranges the information memorize | stored in the random order in the memory | storage part 1 according to the rule which the user specified, arranges it as a some item, and displays it on the display part 2. FIG.

  The operation unit 4 is a part where the user performs a scroll operation, and corresponds to the trackball 30 or the like. That is, the operation unit 4 includes the track ball 30, the wheel 40, or the operation keys described above. The scroll control unit 5 constitutes an operation unit together with the operation unit 4. The control unit 10 includes a scroll control unit 5 and an enumeration number change control unit 6 in addition to the list display control unit 3. A scroll control unit 5 serving as a scroll control means scrolls items displayed on the display unit 2 by the list display control unit 3 in accordance with an operation input from the operation unit 4. The scroll control unit 5 includes a scroll speed control unit 7 that is a scroll speed varying unit that varies the scroll speed.

  The scroll speed control unit 7 gives a scroll speed instruction to the list display control unit 3 in accordance with information on the operation speed of the trackball 30 or the like serving as the operation unit 4. Specifically, the scroll speed control unit 7 instructs the list display control unit 3 to increase the scroll speed as the user operates the trackball 30 or the like faster.

  Further, the scroll speed control unit 7 notifies the scroll speed information to the enumeration number change control unit 6 which is an enumeration number change unit. The enumeration number change control unit 6 displays the list so that the size of the character information or the image information displayed on the display unit 2 by the list display control unit 3 increases or decreases according to the increase or decrease of the scroll speed notified from the scroll speed control unit 7. An instruction is sent to the control unit 3. That is, the character size is changed when the information displayed on the display unit 2 is a character, and the image size is changed when the information is image information. If the displayed information is both a character and an image, the size of the character and the image is simultaneously enlarged or reduced.

  The smaller the character size or image size displayed on the display unit 2, the greater the number of items listed on the display screen. Thereby, the enumeration number change control part 6 can increase / decrease the enumeration number of the item which the list display control part 3 displays on the display part 2 according to increase / decrease in scroll speed.

  Next, a processing procedure of scroll speed instruction and scroll speed information transmission performed by the scroll speed control unit 7 will be described with reference to FIG. Also, a processing procedure for a character size or image size instruction performed by the enumeration number change control unit 6 will be described with reference to the flowchart of FIG. FIG. 2 is a flowchart showing a processing procedure of scroll speed instruction and scroll speed information transmission performed by the scroll speed control unit 7. FIG. 3 is a flowchart showing a processing procedure for a character size or image size instruction performed by the enumeration number change control unit 6. Here, for convenience, the operation unit 4 will be described as the trackball 30. The trackball 30 generates a pulse signal by a magnetic field sensor (not shown) that detects the rotation of the trackball 30. Accordingly, the scroll speed control unit 7 can measure the rotation speed of the trackball 30 by counting the number of pulse signals transmitted from the operation unit 4 per unit time. Further, the detection direction of the magnetic field sensor that is the transmission source of the pulse signal transmitted from the operation unit 4 (whether the magnetic field sensor detects the vertical rotation or the magnetic field sensor that detects the horizontal rotation) is analyzed. Thus, the rotation direction of the trackball 30 can be measured. Thereby, the scroll speed control unit 7 can detect the rotation speed and the rotation direction of the trackball 30 in all 360 degrees.

  As shown in FIG. 2, the scroll speed control unit 7 monitors the operation of the trackball 30 in the operation unit 4 (step S1). The scroll speed control unit 7 detects the operation of the trackball 30 by receiving a pulse signal from the operation unit 4 (Yes in step S2). The scroll speed control unit 7 determines the scroll speed in proportion to the number of pulse signals per unit time sent from the operation unit 4. Further, the scroll direction is determined by analyzing the detection direction of the magnetic field sensor that is the transmission source of the pulse signal (step S3). The scroll speed control unit 7 instructs the determined scroll speed and direction to the list display control unit 3 and sends information on the determined scroll speed to the enumeration number change control unit 6 (step S4).

  Further, as shown in FIG. 3, the enumeration number change control unit 6 receives scroll speed information from the scroll speed control unit 7 (step S10). At this time, if the number of pulse signals indicated by the scroll speed information is less than the threshold (Yes in step S11), the enumeration number change control unit 6 performs list display control for an instruction to set the character size or / and the image size to (large). It gives to part 3 (step S12). Then, the list display control unit 3 sets the character size and / or the image size to (large) according to the instruction. The size at this time is the same as the size before scrolling. If the number of pulse signals indicated by the scroll speed information is greater than or equal to the threshold (No in step S11), the list display control unit 3 sets the character size and / or image size to (small) (step S13). Note that the character size and / or the image size (large) and (small) are respectively predetermined sizes. In addition, it is assumed that the information on the predetermined size is stored in the list display control unit 3. In the display at the size in step S13, the number of display rows (or the number of display columns) is greater than the number of display rows (or the number of display columns) in step S12.

  In the example of FIG. 3, the scroll speed control unit 7 uses one threshold value. However, the number of thresholds used by the scroll speed control unit 7 may be two or more. A processing procedure for a character size and / or image size instruction performed by the enumeration number change control unit 6 using the two threshold values A and B will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing a processing procedure for a character size or image size instruction performed by the enumeration number change control unit 6 using two threshold values A and B.

  As shown in FIG. 4, the enumeration number change control unit 6 receives scroll speed information from the scroll speed control unit 7 (step S20). At this time, if the number of pulse signals indicated by the scroll speed information is less than the threshold A (Yes in step S21), the list display control unit 3 sets the character size and / or image size to (large) (step S22). At this time, the number of display lines is small.

  If the number of pulse signals indicated by the scroll speed information is equal to or greater than the threshold A (No in step S21) and less than the threshold B (Yes in step S23), the enumeration number change control unit 6 determines that the character size and image size are An instruction “middle” is given to the list display control unit 3 (step S24). At this time, the number of display lines is medium. If the number of pulse signals indicated by the scroll speed information is greater than or equal to the threshold A (No in step S21) and is greater than or equal to the threshold B (No in step S23), the enumeration number change control unit 6 determines the character size or / and the image. An instruction to set the size to (small) is given to the list display control unit 3 (step S25). At this time, the number of display lines is the largest. Note that the character size and / or image size (large), (medium), and (small) are predetermined sizes. In addition, it is assumed that the information on the predetermined size is stored in the list display control unit 3.

  Next, specific examples of information display performed by the information display device 20 will be described with reference to FIGS. FIG. 5 is a diagram illustrating a specific example of information display performed by the information display device 20 when character information is displayed as a list. FIG. 6 is a diagram illustrating a specific example of information display performed by the information display device 20 when image information is displayed as a list. FIG. 7 is a diagram illustrating a specific example of information display performed by the information display device 20 when character information and image information are displayed as a list.

  5 to 7, the change between (A) and (C) is due to the flow of FIG. 3, and the change between (A), (B), and (C) is due to the flow of FIG. It has become a thing. In each figure, four items of information are displayed in a list at normal time (during low-speed scrolling). In addition, during medium speed scrolling, six items of information are displayed in a list. In addition, at the time of high speed scrolling, information of 8 items is displayed in a list. The scroll speed is the number of information scrolled per unit time (number of items per row or column). Accordingly, as the scrolling speed increases, the number of items to be displayed increases, so that the speed at which one item flows on the display screen can be kept substantially constant. As a result, even if the scrolling speed changes, the speed at which the user follows one item on the display screen does not change. Therefore, even if the scroll speed changes, the user can keep the ease of visually checking the information content of the item almost constant. Thus, the information display device 20 can realize an information display device that allows the user to easily read item information from the display screen even during high-speed scrolling.

  The trackball 30 can rotate in any direction of 360 degrees due to its nature. For this reason, when the arrangement of the information displayed on the display unit 2 is arranged in any direction of 360 degrees, the scroll may be performed in any direction of 360 degrees. However, as shown in FIGS. 5 to 7, in the case of scrolling only in the vertical direction, only the component in the vertical direction is derived from the pulse signal obtained with respect to any rotation direction of the trackball 30.

(Application example of information display device 20)
Next, an application example of the information display device 20 will be described. In FIG. 1, the information display device 20 has a playback unit 8. For example, the playback unit 8 is a music playback device. The playback unit 8 that is a music playback device receives notification of the music selection result selected from the items on the display screen by the user from the operation unit 4 and plays back the selected music. In such an application example, the character information (Title 01 to 08) illustrated in FIG. 5 is the title of a song or album or the name of a musician. Further, the image information illustrated in FIG. 6 is an album jacket image or a musician image. Also, the character information and image information shown in FIG. 7 are the title of the music or album or the name of the musician, and the jacket image or musician image of the corresponding album. In this way, by applying the information display device 20 to a music playback device, a music playback device that allows a user to easily select a music can be realized.

(Example of the program)
An example of a program that realizes the function of the information display device 20 according to the embodiment of the present invention by installing in the information processing device will be described. Here, the information processing apparatus is a general-purpose computer apparatus.

  By recording the program of this embodiment on a recording medium, the information processing apparatus can install the program of this embodiment using this recording medium. Or the program of a present Example can also be installed in an information processing apparatus directly from the server holding the program of a present Example via a network.

  Thus, the functions of the list display control unit 3, the scroll control unit 5, the enumeration number change control unit 6, and the scroll speed control unit 7 of the information display device 20 according to the embodiment of the present invention are realized using the information processing device. can do. Note that other functions that can be realized by software may also be realized by the program of this embodiment.

  The program of this embodiment includes not only a program that can be directly executed by the information processing apparatus but also a program that can be executed by being installed on a hard disk or the like. Also included are those that are compressed or encrypted.

(Other embodiments)
The embodiment of the present invention can be variously modified without departing from the gist of the present invention. For example, in the above-described embodiment, the trackball 30 is used for the operation unit 4 for the sake of convenience. However, the mouse 41 may be used instead of the trackball 30. Furthermore, you may use together the wheel 40 with which the mouse | mouth 41 is provided. The wheel 40 is used for a vertical scroll operation. As with the trackball 30, the mouse 41 can be operated in any direction of 360 degrees. However, when the pointer of the mouse 41 reaches the end on the display screen, it stops there. Therefore, it is preferable to detect the operation speed based on the moving speed of the pointer until the pointer moves on the display screen and reaches the end.

  Alternatively, the operation unit 4 may be a push button using a tactile switch or the like. That is, only one item is scrolled when the push button is short-pressed, and high-speed scrolling is performed when the push button is long-pressed. Alternatively, it is possible to scroll only one item when the push button is short-pressed, to perform medium-speed scrolling when the push button is continuously pressed twice, and to perform high-speed scrolling when the push button is pressed three times continuously.

  In the above-described embodiment, the display size when scrolling at low speed is the same as when display is not scrolling. However, when scrolling is not performed, the display size is slightly smaller. It may be slightly larger than the time display. If it does in this way, even if it starts scrolling, it will become easy to see like when it is not scrolling.

  In the above embodiment, when the character size or the image size is changed, the same vertical or horizontal enlargement or reduction is performed. However, in the scroll direction, for example, in FIGS. Only enlargement or reduction may be performed. In particular, in the case of characters, there is no problem as long as it can be read even if there is some deformation. Further, the gap between items may be changed instead of the size of characters and images. That is, in the case of FIG. 5 (A), the relationship between “Title 01” and “Title 02” in FIG. 5 (C) is the same by eliminating the gap between “Title 01” and “Title 02”. The character size in FIG. 5A can be the same as the number of lines in FIG. Moreover, it is good also as what combined this clearance gap and the change of size.

  The display unit 2 serving as a display unit can be realized by liquid crystal, organic electroluminescence (EL), or the like. The control unit 10 serving as a control means can be realized by a CPU (Central Processing Unit) or the like. The storage unit 1 can be realized by an HDD (Hard Disk Drive), a semiconductor storage device, or the like.

  Moreover, the display unit 2 and the list display control unit 3 are exemplified as the list display means, but these two functional blocks may be integrated into one list display unit including the control unit 10. Further, as the scroll control means, the scroll control section 5 including the scroll speed control section 7 which is a scroll speed varying means is illustrated, but these two functional blocks may be separated into two functional blocks. Further, although the enumeration number change control unit 6 is illustrated as the enumeration number change means, this functional block may be a functional block including the scroll speed control unit 7 or the list display control unit 3.

  In the above-described embodiment, an example in which a list is displayed has been described. However, the present invention can be applied to character information extending over several lines, image information arranged vertically and horizontally, and the like instead of the list display.

  The present invention can be used for any device having a display unit for displaying information.
