Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for performing predetermined information processing in response to a user's operation input, for example, a navigation device which allows a user to set a destination and designate a map to be displayed. The present invention relates to an information processing device to be executed.

[0002]

2. Description of the Related Art Hitherto, there has been known a navigation apparatus that displays a vehicle position on a display together with a road map to smoothly reach a destination. And
Because of the commonality of displaying a screen on a display in this way, it is possible to switch to a television screen, a video CD screen, or the like and display the same on the same display.
Further, for example, in the case of a navigation device, a plurality of selection method candidates for setting a destination are displayed so that the user can freely select a desired selection method. For example, you can directly enter a phone number or address, or select a category called facility name,
For example, a frequently used point is registered, and it is called up and set as a destination. From the viewpoint of displaying the selection candidates for facilitating the operation input in this way, for example, when displaying the above-mentioned television screen, it is necessary to display the channel number of the television or to display the video CD screen. Operation screen (play /
Fast forward, rewind, pause, switching between primary and secondary audio, etc.).

In addition to the operation input for controlling the contents displayed on the screen, such as the navigation screen, the television screen, and the video CD screen, for example, the operation screen of an air conditioner and the operation screen of a telephone device are also displayed. It is possible to make it possible. In other words, with the diversification of in-vehicle equipment, if an operation screen corresponding to the equipment type is displayed and a desired operation can be selected from it,
This is effective in improving convenience.

[0004]

However, the size of the display cannot be so large, especially when considering an on-vehicle display. Therefore, the item unit which is an operation input candidate when displayed as an operation screen is: There are restrictions on the size of the characters and the content that describes the function. As a result, for example, a user with presbyopia may not be able to sufficiently read the characters indicating the item contents, and may need to prepare special reading glasses or the like by himself. In particular, it is inconvenient if the driving of the vehicle itself can be executed with the naked eye but reading glasses are required for the operation input.

[0005] In addition, even though the characters of the item contents can be seen, the meaning of the item contents cannot be fully understood, and the user may not be able to input the desired operation.
Also, it is assumed that changing to a completely different function that is not intended makes it difficult to return from that state to the original state, and eventually ends up being unable to change to the desired function itself Is done.

[0006] Therefore, the present invention enables the user to easily confirm whether the input item selected by the external operation is the one desired by the user when executing information processing according to the external operation of the user, It is an object of the present invention to provide an information processing device that facilitates appropriate operation input for a specific user.

[0007]

According to the first aspect of the present invention, there is provided an information processing apparatus which is selected from a plurality of input items by an external operation by a user. An operation input unit for inputting various instructions based on the result is provided, and the processing execution unit executes information processing based on the instruction from the operation input unit. At this time, on the screen of the display means, a plurality of input items selectable by the operation input means are displayed,
The user can select a desired one by looking at the displayed input item.

However, the size of the screen of the display means is limited according to the application destination. For example, when it is used for a vehicle, it must be relatively small. When the number of input items is large, there are restrictions on the size of characters and the contents for explaining functions. As a result, for example, if the user has presbyopia, the characters indicating the item contents themselves cannot be seen sufficiently, so that it is necessary for the user to prepare specially reading glasses or the like. In particular, if the driving of the vehicle itself can be performed with the naked eye, but reading glasses are required for operation input, it is inconvenient to wear it only at that time. In addition, even though the characters of the input items are visible, the meaning of the contents of the items cannot be fully understood, and the user may not be able to perform the desired operation input. And
By changing to a completely different function that is not intended,
It becomes difficult to return from that state to the original state,
Eventually, it is also assumed that the change to the desired function itself cannot be made and ends. In this case, it is often possible to solve the problem by reading the manual, but it is inconvenient to read the manual each time.

Therefore, when a specific external operation is performed on the operation input means, the processing execution means of the information processing apparatus of the present invention provides a predetermined auxiliary guidance for the input item selected by the external operation on the operation input means. On the other hand, when a specific external operation is not performed on the operation input unit, the selected input item is determined, and information processing is performed based on the determined input item. As described above, the user who desires the auxiliary guidance may perform a specific external operation, and the user who does not desire the auxiliary guidance need not perform such an external operation.
That is, if the auxiliary guidance is provided uniformly, unnecessary auxiliary guidance is forcibly performed even to a user who does not desire, so that the desired user can be dealt with according to the wish.

The auxiliary guidance in this case is guidance for the purpose of assisting a user who cannot easily see the characters of the input item or who cannot fully understand the meaning of the contents of the input item. As a specific auxiliary guide, for example, it is conceivable to enlarge and display the selected input item on the screen of the display means. This is auxiliary guidance for a user who is difficult to see small characters, and only the selected input item may be displayed in the full display area. By providing such auxiliary guidance, a user who is difficult to see small characters can confirm whether or not the input item selected by the user is the desired one, which is effective for realizing appropriate operation input.

It is also conceivable to display a description of the content of the selected input item on a screen. Such auxiliary guidance is effective as guidance for a user who cannot fully understand the meaning of the input item contents. Of course, in consideration of convenience for a user who is difficult to see small characters, it is also preferable to display the characters of the content description in a large size.

The operation input means may be a panel switch method using a hardware switch or a remote control switch method. An input item is selected by pressing an area corresponding to the input item on the screen of the display means. Touch switch type ". Since the input means is recognized on the screen by displaying the screen on the display means, and the area corresponding to the recognized input item can be pressed and selected, the convenience is improved.

On the other hand, the auxiliary guidance may be provided by voice instead of the above-described display. For example, a voice output means for outputting a voice signal for guidance is provided, and a description of the content of the selected input item is output via the voice output means.
That is, when visual recognition is difficult, it is also possible to perform auditory recognition.

By the way, for example, in presbyopia (presbyopia), the elasticity of the crystalline lens gradually decreases with aging, the near point of accommodation becomes longer than the clear vision distance, and the ability to focus the eye on a nearby object is reduced. In this case, it is more appropriate to wear so-called reading glasses than simply enlarge the character to be viewed. Therefore, it is conceivable to provide the following eyesight assisting means. That is, a plurality of corrective lenses having different refractive indexes are provided, and the plurality of corrective lenses are configured to be switchably disposed in front of the screen of the display means. For example, there is a system that lends reading glasses in a public facility, and in this case also, in many cases, a plurality of refraction degrees are prepared according to the correction degree. Similarly, a plurality of correction lenses having different refractive indices are prepared so as to perform correction according to a plurality of presbyopia degrees. By arranging the desired correction lens in front of the screen, the user can appropriately recognize the contents of the screen display.

If the user has presbyopia, there is no problem if the user has his own reading glasses, but in the case of the present invention, there is no need to specially prepare such reading glasses. . In particular, even though the vehicle itself can be executed with the naked eye because it has the legal eyesight, if reading glasses are required for operation input, wear the reading glasses only during the operation. It must be inconvenient. In other words, since the reading glasses are carried only for the operation, it is preferable in terms of usability that the device to be used is provided with such means.

Although the information processing apparatus of the present invention can be applied to various devices, it is particularly realized as an on-vehicle navigation device, a device for controlling other on-vehicle equipment, or a multimedia system integrating them. It is possible to do. For automotive use,
As described above, there are many situations in which the screen size of the display means must be reduced, which is more effective. In addition, particularly in the case of navigation, there are many methods for setting the destination. For example, when selecting from the addresses in the navigation, there are also items that the user must select and specify for a search based on the order of the Japanese syllabary. Many. Therefore, when targeting a general user, it is necessary to display a certain number of input items on one screen. Therefore, it is preferable to consider the above-mentioned presbyopia user from the viewpoint of improving the convenience of the user.

Embodiments of the present invention will be described below with reference to the drawings. It is needless to say that the embodiments of the present invention are not limited to the following examples, and can take various forms as long as they belong to the technical scope of the present invention. [First Embodiment] FIG. 1 is a block diagram showing a schematic configuration of a multimedia system as an embodiment. This multimedia system is installed in a vehicle and comprehensively controls or provides information on image display using other media, telephone devices, air conditioners, etc., including navigation such as map display and travel guidance using map data. It is configured as a processing system. Specifically, the multimedia ECU 10, the display device 15 with a touch switch, the TEL-ECU 51, the TV tuner 52, the audio device 53, and the air conditioner ECU 5
4 and the CD changer 55 are connected to each other via the communication line 40.

A position detector 4, a map data input device 6, and a group of operation switches 8 are connected to the multimedia ECU 10 (corresponding to the processing execution means of the present invention). Data can be input and output to and from the switch-equipped display device 15. The multimedia ECU 10 includes a navigation control unit 10a and a multimedia control unit 10b, each of which is a well-known CPU, ROM,
It is configured as a normal computer including a RAM, an I / O, and a bus line for connecting them. In other words, the navigation control unit 10a becomes a subject that executes navigation-related processing, and the multimedia control unit 10b controls other media, specifically, the T
The main unit executes processing related to the EL-ECU 51, the TV tuner 52, the audio device 53, the air conditioner ECU 54, and the CD changer 55.

The position detector 4 is a GPS (Global Pos.) For detecting the position of a vehicle based on radio waves from a well-known gyroscope 18, a distance sensor 20, and satellites.
and a GPS receiver 22 for the itioning system). Each of these sensors 18, 20, and 22 has an error having a different property.
Each is configured to be used while interpolating. It should be noted that depending on the accuracy, a part of the above-described components may be used, and a rotation sensor for the steering wheel, a wheel sensor for each rolling wheel, or the like may be used.

The map data input device 6 is a device for inputting various data including so-called map matching data, map data and landmark data for improving the accuracy of position detection. As a medium, CD-R
Generally, an OM or a DVD is used, but another medium such as a memory card may be used.

The display device 15 with a touch switch, when touching the screen with a finger, cuts off a predetermined number of infrared rays running in the vertical and horizontal directions of the screen, identifies the pressed area, and performs the switch function (the present invention). And a display E for controlling the entire display device.
It includes a CU 13 and an LCD monitor 14 (corresponding to the display means of the present invention). The LCD monitor 14 is capable of color display. The screen displays a current vehicle position mark input from the position detector 4, map data input from the map data input device 6, and guidance for displaying on the map. A route and additional data such as a mark of a set point to be described later can be displayed in a superimposed manner. This is a method of use as a navigation device. For example, a television image of a channel selected by the TV tuner 52 or a CD changer 5
5 can also be displayed.

When the present system operates as a navigation system, when the position of the destination is input by the touch switch 12, the multimedia ECU 1
The zero navigation control unit 10a executes so-called route guidance that automatically selects an optimal route from the current position to the destination and forms and displays a guidance route. As a technique for automatically setting the optimum route, a technique such as the Dijkstra method is known.

In the case of the present embodiment, the operation switch group 8 is a mechanical switch arranged around the display device 15 with a touch switch (or integrally with the housing of the display device). Is used to select the media to be used for the job. Specifically, it is a switch for selecting a desired one from various media such as navigation, telephone, television, audio, air conditioner, and CD.

For example, if "navigation" is selected, a screen for navigation is displayed on the LCD monitor 14. Examples of the navigation screen include a menu screen, a map display screen, and various guidance screens. Also,
When "telephone" is selected, for example, a ten key screen is displayed for inputting a telephone number, and a telephone call can be made by directly touching the screen. Note that the TEL-ECU 51 has a telephone directory function, and if there is registered telephone number data or the like, it may be displayed.

On the other hand, when "TV" is selected,
It is conceivable to display a list of selectable TV channel numbers, a list screen of image / audio adjustment items, and the like. The same applies when audio is selected. When "air conditioner" is selected, a screen of an adjustment item for instructing a current set temperature, temperature rise / fall, or the like may be displayed.

Similarly, when "CD" is selected, a list of selectable CD types (video CD, music CD, etc.) is displayed, and well-known instructions such as reproduction, fast forward, rewind, and pause are also displayed. May be included. As described above, according to the multimedia system of this embodiment, when a medium to be used is selected, a menu screen corresponding to the medium is displayed on the LCD monitor 14 of the display device 15 with a touch switch.
If the user touches a desired input item on the screen, the touch is detected by the touch switch 12 and transmitted to the multimedia ECU 10 to execute a predetermined corresponding process.

However, the screen size of the LCD monitor 14 is limited. In particular, in the case of the present embodiment, since it is mounted on the vehicle, it has to be reduced in size. If the number of input items is large or other information must be prioritized, the size of characters and the contents of the function are naturally limited. For example, FIG. 5A is an example of a screen display when a navigation-related process is being executed. In this case, a map (not shown) is displayed on the screen G indicated by the frame. That is, in this case, the map to be displayed with priority is the map. Then, in order to enable operation input by the touch switch 12 (see FIG. 1), a switch for instructing to return to the main menu, a switch for instructing to switch the map direction, and a switch for instructing to search the guide route again are made. They are displayed on the periphery of the screen G so as not to disturb the map display as much as possible. FIG.
In the case of (a), it is displayed near the lower end of the screen G.
As described above, the size of the characters is reduced, and the contents of the items for explaining the functions are simple, such as "menu", "switch map direction", and "re-search".

As a result, for example, when the user cannot sufficiently see the characters indicating the item contents due to presbyopia or the like, it is necessary for the user to prepare special reading glasses or the like. In particular, if the driving of the vehicle itself can be performed with the naked eye, but reading glasses are required for operation input, it is inconvenient to wear it only at that time.
In addition, even though the characters of the input items are visible, the meaning of the contents of the items cannot be fully understood, and the user may not be able to perform the desired operation input. Also, it is assumed that changing to a completely different function that is not intended makes it difficult to return from that state to the original state, and eventually ends up being unable to change to the desired function itself Is done. In this case, it is often possible to solve the problem by reading the manual, but it is inconvenient to read the manual each time.

Therefore, in the multimedia system of the present embodiment, the following processing is executed to solve this problem. That is the operation input receiving process shown in FIG. This processing is executed by the multimedia ECU 10, but is executed when the system is started by turning on a power supply (not shown) and a screen including some input items is displayed on the LCD monitor 14. In other words, the menu screen for any one of the above-described plurality of used media, or, as described with reference to FIG. 5A, items that can be operated and input are displayed along with other main display contents. It is executed in any state if it is.

First, after the operation number counter C is cleared (C = 0) in step S10, it is determined whether or not there is an operation input (S20). When there is an operation input (S
20: YES), the operation number counter C is incremented (C ← C + 1) (S30). Based on the operation number counter C, it is determined whether or not this is the first operation input (S40). If it is the first operation input (S40: YES), it is determined whether a predetermined time (for example, one second) has elapsed (S50), and if the predetermined time has not elapsed (S50: NO). ), It is determined whether there is an operation input (S60).

Without the second operation input (S60: N
O), if the predetermined time has elapsed (S50: YE
S), the input item for which the operation has been input is determined (S70), and the operation input reception processing routine ends. When the input item is determined in S70, the input item is determined in a main processing routine (not shown), and processing corresponding to the input item is executed. For example, when the screen is as shown in FIG. 5A, the part displayed as "Menu" is touched, and after a predetermined time has elapsed, the screen is switched to a screen for displaying a menu list. Similarly, the user touches a part displayed as "switch map direction" and switches the map direction after a predetermined time has elapsed. Also. Touch the part where "Research" is displayed, and after a predetermined time elapses,
A route search is performed. Since these contents are publicly known, they will not be described in detail, but only the switching of the map direction will be supplementarily described.

In the present embodiment, as in the case of a general commercial map, the map is fixed in the north direction (also referred to as north-up) and the traveling direction of the vehicle is displayed with the traveling direction of the vehicle upward. Fixed direction (also called heading up)
There are two types. Then, each time the input item of "map direction switching" is determined, the fixed north direction and the fixed traveling direction are set alternately.

Returning to the description of the flowchart of FIG.
0, that is, before the predetermined time elapses (S
50: NO) If there is a second operation input, S
The flow shifts to 30 to increment the operation number counter C. As a result, C = 2. Therefore, a negative determination is made in S40, and the process proceeds to S80, where the auxiliary guidance process is executed.

Here, the auxiliary guidance processing in S80 will be described with reference to FIGS. FIG. 3 is a flowchart showing the auxiliary guidance processing (part 1). The processing is only to enlarge and display the selected input item (S11).
0) After the enlarged display, the process proceeds to S90 in FIG.
Note that FIG. 5B shows an example in which “map direction switching”, which is one of the input items, is enlarged and displayed. In this example, the characters are displayed in a so-called “four-fold character,” which is twice as large in the vertical and horizontal directions as the character size of the normal input item.

FIG. 4 is a flowchart showing an auxiliary guidance process (2). First, the selected input item is enlarged and displayed, and a description of the item content is also displayed (S210). FIG. 5C shows an example in which “map direction switching”, which is one of the input items, is enlarged and displayed, and an explanation of the item is also displayed. In this example, the input items are displayed in “quadruple characters” and the item descriptions are also displayed in the same quadruple characters. The description of this item is, for example, "the current setting is fixed north upward with the north facing upward, and the traveling direction is fixed upward when the SW is pressed again." Then, not only such display is made, but also the explanation of the item contents is given by voice (S220). This is a process of outputting the contents of the above-described item description as a synthesized voice. In this case, the multimedia ECU 10 instructs the audio device 53 to execute the voice output. After the explanation of the voice, S9 of FIG.
Move to 0.

In this embodiment, by setting a predetermined mode, one of the auxiliary guidance processing (part 1) of FIG. 3 and the auxiliary guidance processing (part 2) of FIG. 4 is selected. It can be executed. Therefore, if the user of the vehicle switches the mode setting by himself / herself or at a vehicle dealer or the like, the desired auxiliary guidance process can be selected. This is because the intention of the auxiliary guidance processing in FIGS. 3 and 4 is different. That is, in the case of the auxiliary guidance process (part 1) of FIG. 3, since the characters of the input items are merely enlarged as shown in FIG. The content itself is for users who understand. On the other hand, in the case of the auxiliary guidance process (part 2) in FIG. 4, not only the characters of the input items are enlarged but also the item descriptions are displayed as shown in FIG. 5C. Therefore, it is suitable for users who need to explain the contents of the input items themselves, as well as being difficult to see with normal character size.

At step S90 in FIG. 2 where the auxiliary guidance screen shown in FIG. 5B is displayed, or the auxiliary guidance screen as shown in FIG. The operation number counter C is cleared (C = 0). Then, the process returns to S20 and waits for an operation input. If there is an operation input (S20: YES), the above-described processing after S30 is executed. Therefore,
Touch the relevant area in the state where the auxiliary guidance screen is as shown in FIG. 5B or FIG. 5C, and if a predetermined time elapses (S40: YES, S50: YE)
S), the input item is determined.

As described above, in the multimedia system according to the present embodiment, after a part of the input item displayed on the LCD monitor 14 is pressed once, nothing is done and a predetermined time elapses, and the determination is made as it is. When the same part is pressed within a predetermined time, auxiliary guidance such as enlarged display of characters is performed. Therefore, a user who wants the auxiliary guidance need only press twice, and a user who does not want to do so is one. You only have to press it once. In other words, if assistance guidance is provided uniformly, unnecessary assistance guidance will be forcibly provided to undesired users, so that desired users can be dealt with according to their wishes. .

If the input items are enlarged and displayed, it is possible for a user who cannot easily see small characters to check whether or not the input items selected by the user are the desired ones. This is effective for realizing appropriate operation inputs. It is. In addition, if a description of the content of the selected input item is also displayed, it is effective as a guide for a user who cannot fully understand the meaning of the content of the input item. Of course, it is more preferable for such a user to display the text of the content description in a large size in consideration of convenience for a user who is difficult to see small characters. Then, as in the auxiliary guidance process (No. 2) shown in FIG. 4 described above, it is more preferable to provide the auxiliary guidance not only by display but also by voice. That is, when visual recognition is difficult, it is also possible to perform auditory recognition.

In the above example, the input item of switching the map direction using the navigation function has been described. However, the same applies to other input items relating to navigation, and other media other than the navigation function are used. The same applies to the case. In other words, when the telephone function is selected, a numeric keypad screen is displayed to enter the telephone number, and if you can make a call by directly touching the screen, The key may be enlarged and displayed. Further, when the TEL-ECU 51 has a database of telephone number data, when a list thereof is displayed, only a part thereof may be enlarged and displayed. In addition, the channel number list screen when the TV function is selected,
The same applies to a list screen of the image / audio adjustment items. [Second Embodiment] By the way, for example, presbyopia (presbyopia) gradually decreases the elasticity of the crystalline lens with aging, the near point of accommodation becomes longer than the clear vision distance, and the eye focuses on a nearby object. It is said that the matching ability is reduced. In this case, it is more appropriate to wear so-called reading glasses, instead of simply increasing the size of the character to be viewed. However, in that case, the user must prepare the reading glasses by himself, and in particular, despite having the legal eyesight, the vehicle itself can be executed with the naked eye, but the operation input of the multimedia system For this reason, when reading glasses are required, it is inconvenient to wear the reading glasses only during the operation. In other words, the reading glasses are carried only for the operation. Therefore, it is preferable in terms of usability that the device used has a mechanism that performs the same function.

Therefore, it was considered to provide the following visual acuity assisting means. That is, a plurality of correction lenses having different refractive indices are provided, and the plurality of correction lenses can be arranged so as to be switched to the front of the screen of the LCD monitor 14.
For example, there is a system that lends reading glasses in a public facility, and in this case also, in many cases, a plurality of refraction degrees are prepared according to the correction degree. Similarly,
A plurality of correction lenses having different refractive indices are prepared so that correction can be performed according to a plurality of presbyopia degrees. By arranging the desired correction lens in front of the screen, the user can appropriately recognize the contents of the screen display.

There are various possible arrangements for disposing the correcting lens in front of the screen. For example, as shown in FIG. 6, five correcting lenses each having a different refractive index and being formed into a substantially rectangular shape are provided. Lens unit L
U1, LU2, LU3, LU4, and LU5 are arranged in parallel. By supporting the corners of the lens units LU1 to LU5 with the support shaft 100, the lens units LU1 to LU5 are rotatable about the support shaft 100. By doing so, for example, although shown as the lens unit LU4 in FIG. 6, an arbitrary lens unit can be arranged in front of the LCD monitor 14. It is more convenient to provide a mechanism for fixing the lens unit in a state where the lens unit is arranged in front of the LCD monitor 14 as described above. Further, a lens unit that is not selectively used may be configured to be removable. [Others] For example, in the above-described embodiment, an example has been described in which the multimedia system is realized as a vehicle-mounted system, but the application destination is not limited to the above-described vehicle-mounted system. For example, the present invention may be applied to a portable navigation device, or to an information terminal device which is installed in a street or a parking area for providing route guidance or the like.
