Description

  The present invention relates to a display system and a display program.

  Conventionally, a system that detects a user's viewpoint on a screen and performs various processes depending on the viewpoint is known. Patent Document 1 describes that in order to prevent “burn-in” of the screen, the brightness of an image other than the image being watched by the user is reduced, simplified, or displayed with increased transparency. .

JP-A-10-282877

However, if all objects other than the object with the viewpoint are displayed with lower visibility than the object with the viewpoint, the visibility is lowered even if the object is related to the object with the viewpoint. For this reason, the user can easily recognize only the object whose viewpoint is adjusted, compared with other objects, but there is a problem that it is difficult to recognize the object related to the object whose viewpoint is adjusted.
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a technique for easily displaying an object in a screen on the basis of a viewpoint.

  In order to achieve the above object, the display system includes a viewpoint detection unit that detects the viewpoint of the user, a first object having the viewpoint and a second object related to the first object, the first object and the second object. A display control unit that causes the display unit to display with higher visibility than a third object other than the above.

  Furthermore, in order to achieve the above object, the display program includes a computer, a viewpoint detection unit that detects a viewpoint of the user, a first object having the viewpoint, and a second object related to the first object, the first object And it is made to function as a display control part displayed on a display part by visibility higher than 3rd objects other than a 2nd object.

  That is, in a display system and a program, when a viewpoint exists in a 1st object, a 2nd object is also displayed on a display part with a visibility higher than a 3rd object with a 1st object. Therefore, when the user focuses the viewpoint on the first object, the user can easily view not only the first object but also the second object.

It is a block diagram of a display system. 2A to 2D are diagrams showing map display screens. FIG. 3A is a diagram showing a correspondence relationship between display layers and objects, and FIG. 3B is a diagram showing objects belonging to a group and objects not belonging to the group. It is a flowchart which shows a screen display process. 5A and 5B are diagrams showing examples of related regions.

Here, embodiments of the present invention will be described in the following order.
(1) Configuration of display system:
(2) Screen display processing:
(3) Other embodiments:

(1) Configuration of display system:
FIG. 1 is a block diagram showing a configuration of a display system 10 according to an embodiment of the present invention. The display system 10 includes a control unit 20 including a CPU, a RAM, a ROM, and the like, and the control unit 20 can execute a desired program recorded in the ROM or the recording medium 30.

  In the present embodiment, the control unit 20 can execute a navigation program (not shown), and can execute each function of route guidance by executing each program. That is, the control unit 20 displays a map on the display 40 as a display unit by executing the navigation program, and guides the vehicle on which the display system 10 is mounted to a specified destination based on a GPS signal (not shown). can do.

  In the present embodiment, the control unit 20 executes a display program 21 recorded in a ROM, a recording medium 30 or the like (not shown) in order to provide a user interface related to functions realized by the respective programs as described above. In order to execute processing by the display program 21, the vehicle includes a display (display unit) 40, a touch pad 41, and a line-of-sight detection sensor 42.

  The display 40 is connected to the control unit 20 via an interface (not shown). The control unit 20 outputs a control signal to the display 40 to designate arbitrary coordinates and display an arbitrary image on the display 40. Can be displayed. The touch pad 41 is an input device including a rectangular flat contact detection surface, detects a position where a detection target object is in contact with the contact detection surface, and outputs coordinates indicating the detection position. The control unit 20 acquires the contact position based on the coordinates.

  The line-of-sight detection sensor 42 includes an infrared output unit and at least two infrared cameras. The infrared camera is attached to a vehicle interior structure (for example, a wall surface of an instrument panel) so as to include the driver's face in the field of view. The infrared camera detects and outputs an eye position and a user's line-of-sight direction (vector) based on an image of a user's (driver's) eye photographed by infrared rays output from the infrared output unit. Based on the output, the control unit 20 can specify the eye position and line-of-sight direction in a predefined three-dimensional space. The line-of-sight direction is acquired as, for example, a direction connecting a reference point set for each eye and a moving point whose position changes according to the movement of the eyeball, and various other methods may be employed. In addition, although the user's line-of-sight direction can be specified in one direction based on the average value of the line-of-sight directions specified in each of both eyes, various methods can be adopted as the method of specifying the line-of-sight direction.

  In the above configuration, the control unit 20 uses the display 40 and the touch pad 41 as a user interface, and receives input from the user via the user interface screen. For this purpose, the display program 21 includes a viewpoint detection unit 21a, a display control unit 21b, and an input reception unit 21c.

  The viewpoint detection unit 21a is a program module that causes the control unit 20 to realize a function of detecting a user's viewpoint. In the present embodiment, the position of the display 40 serving as a viewpoint detection area is specified in advance by a three-dimensional coordinate system that defines the position of the vehicle interior space. The control unit 20 acquires the position and line-of-sight direction of the user's eyes based on the output of the line-of-sight detection sensor 42, and the position and line-of-sight direction of the user's eyes within the three-dimensional coordinate system in which the position of the screen is defined. Is identified. Then, an intersection point between a virtual line extending in the line-of-sight direction from the eye position and the display surface of the display 40 is specified as a viewpoint. When the viewpoint does not exist on the screen, for example, the viewpoint may be indefinite, or may be determined to exist on another structure (for example, an instrument panel or the like).

  The display control unit 21b is a program module that causes the control unit 20 to realize a function of displaying a user interface screen on the display 40 (display unit). Image information (map drawing information, icon drawing information, etc.) for drawing an object constituting the user interface screen is recorded in advance on the recording medium 30 as display information 30a. When the control unit 20 executes the navigation program, the control unit 20 draws (records) a user interface screen including a map or the like on the RAM with reference to the display information 30a. The control unit 20 acquires information on the drawn user interface screen by the processing of the display control unit 21b, and outputs a control signal for displaying the user interface screen to the display 40. As a result, a user interface screen in the navigation program is displayed on the display 40.

  In addition, the display control unit 21b identifies an object having a viewpoint, and sets an object having a viewpoint (first object) and an object related to the object (second object) to objects other than the first object and the second object. The control unit 20 is caused to realize a function of displaying on the display 40 with higher visibility than (third object).

  FIG. 2A is an explanatory diagram for explaining objects that can be displayed on a map display screen as an example of a user interface screen in the navigation program. In the map display screen, three display layers from the first layer to the third layer are defined. When objects of different layers exist at the same coordinates on the display, the objects of the upper layer are displayed with priority. That is, the portion of the lower layer object that overlaps the display position of the upper layer object is not displayed. The first layer is the highest layer and the third layer is the lowest layer. The second layer is ranked between the first layer and the third layer.

  FIG. 3A is a diagram illustrating objects displayed on each layer. As shown in the figure, a map M is displayed on the third layer. The map M is displayed over the entire map display screen. Button B (B1-B6), the compass C, and the address display part A are displayed on a 2nd layer. The button B is an object for instructing execution of various functions of the navigation program. The compass C is an object that indicates the orientation of the map M displayed on the map display screen. The address display unit A is an object indicating an address corresponding to the center coordinates of the map M displayed on the map display screen. The button B, the compass C, and the address display unit A are displayed in a predetermined shape at a predetermined position on the map display screen.

A pointer P is displayed on the first layer. The display position of the pointer P moves according to the user's operation on the touch pad 41. That is, the control unit 20 updates the position of the pointer P displayed on the map display screen of the display 40 according to the direction of the swipe operation on the touch pad 41, the moving amount, and the moving speed.
In the present embodiment, all objects that can be displayed on the map display screen are displayed in color. However, the map M is displayed in a gray scale in a specific case described later.

  The control unit 20 can acquire the position where the viewpoint exists on the map display screen by the processing of the viewpoint detection unit 21a. In addition, the control unit 20 can specify the object displayed at the position where the viewpoint exists with reference to the display position of each object.

  The objects that can be displayed on the map display screen are grouped in advance based on the relevance. In this embodiment, a representative object and a related object are defined for each group. The representative object is an object serving as an index when searching for an object having a viewpoint, that is, a group to which the first object belongs. The related object is an object other than the representative object belonging to the group to which the first object belongs as the representative object, and corresponds to the second object. Further, when attention is paid to an arbitrary group, an object that does not belong to the group corresponds to a third object.

  Some objects may belong to multiple groups. FIG. 3B shows groups in this embodiment. As shown in the figure, the compass C and the address display unit A belong to the group G1 in which the map M is a representative object as related objects. Button B and pointer P correspond to objects that do not belong to group G1. A map M as a related object belongs to the group G2 having the address display unit A as a representative object. Button B, compass C, and pointer P correspond to objects that do not belong to group G2. The compass C, the address display part A, and the pointer P belong to the group G3 in which the button B is a representative object. The map M corresponds to an object that does not belong to the group G3.

  In the present embodiment, among the objects corresponding to the third object, the objects linked to the first layer or the second layer are made transparent (not displayed), thereby making the first object and the second object the first object. Display with higher visibility than three objects. Further, among the objects corresponding to the third object, the objects linked to the third layer are displayed in gray scale so that the first object and the second object which are color images are higher than the third object. Display with visibility.

  The input receiving unit 21c is a program module that causes the control unit 20 to realize a function of receiving a user's input from a viewpoint on the screen and a function of receiving a user's operation input to the touch pad 41. When the control unit 20 receives a swipe operation on the touch pad 41 when the viewpoint is present on the button B by the processing of the input receiving unit 21c, the control unit 20 moves the display position of the pointer P according to the direction and speed of the swipe operation. In addition, when the control unit 20 receives a swipe operation on the touch pad 41 when the viewpoint is present on the map M or the address display unit A by the processing of the input receiving unit 21c, the control unit 20 displays the map M according to the direction of the swipe operation and the moving speed. Scroll.

  As described above, in the present embodiment, the object whose display position is changed in accordance with the swipe operation is switched according to the object having the viewpoint. The user recognizes whether the object whose display position changes with the swipe operation is the map M or the pointer P by displaying one with higher visibility than the other. Further, when the display position of one of the objects of the map M or the pointer P is changed, an object assumed to be referred to by the user in addition to the object is also displayed with higher visibility than the other object. .

(2) Screen display processing:
Next, screen display processing executed by the control unit 20 will be described with reference to FIG. The screen display process shown in FIG. 4 is a process for changing the display mode of an object in accordance with an object having a viewpoint, and will be described using the above-described map display screen as an example. The screen display process is repeatedly executed by the control unit 20 while the viewpoint is present on the display 40. When the screen display process shown in FIG. 4 is started, the control unit 20 acquires the viewpoint of the user by the process of the viewpoint detection unit 21a (step S100). That is, the control unit 20 acquires the coordinates where the viewpoint is located in the screen. Subsequently, the control unit 20 specifies a group to which an object with a viewpoint belongs as a representative object by the processing of the display control unit 21b (step S105).

  Subsequently, the control unit 20 determines whether or not the processing of all objects has been completed by the processing of the display control unit 21b (step S110). Each object constituting the map display screen is a processing target of steps S115 to S130 one by one from the object linked to the lowest layer. Therefore, in step S110, it is determined whether or not the processing of all the objects constituting the map display screen has been completed.

  If it is not determined in step S110 that all objects have been processed, the processes in steps S115 to S130 are repeated for objects that have not yet been processed. In step S115, the control unit 20 determines whether the processing target object belongs to the group specified in step S105 by the processing of the display control unit 21b.

  When it is determined in step S115 that the processing target object belongs to the specified group, the control unit 20 sets the processing target object to be non-transparent by the processing of the display control unit 21b (step S120). On the other hand, when it is not determined in step S115 that the processing target object belongs to the specified group, the control unit 20 reduces the visibility of the processing target object by the processing of the display control unit 21b (step S125).

  Specifically, in step S125, when the display layer of the object corresponding to the object that does not belong to the specified group is the lowest layer, the control unit 20 displays the object in grayscale. In step S125, when the display layer of the object corresponding to the object that does not belong to the specified group is other than the lowest layer, the control unit 20 sets the object to be transparent.

  After the processing of step S120 or step S125, the control unit 20 draws the processing target object at the address corresponding to the display position of the object in the RAM by the processing of the display control unit 21b (step S130). When step S125 is executed, step S130 is substantially skipped because it is not necessary to draw the processing target object set to be transparent in the RAM.

  When it is determined in step S110 that drawing of all objects has been completed, the control unit 20 displays a screen constituted by objects drawn in the RAM by the processing of the display control unit 21b. That is, the control unit 20 outputs a control signal for displaying a screen drawn in the RAM to the display 40. As a result, a screen is displayed on the display 40.

  By repeatedly executing the above screen display processing, the display system 10 can guide the object having the user's viewpoint and the object in a state in which the object is easier to visually recognize than the other objects. Specific examples will be described below.

  FIG. 2B shows a map display screen that is displayed when the viewpoint of the user exists on the map M. As shown in FIG. 3B, a compass C and an address display unit A belong as related objects to the group G1 to which the map M belongs as a representative object. As shown in FIG. 3B, the button B and the pointer P correspond to objects that do not belong to the group G1. Therefore, on the map display screen shown in FIG. 2B, the map M, the compass C, and the address display section A are displayed, and the button B and the pointer P are transparent (not displayed).

  The user desires the map M by performing a swipe operation on the touch pad 41 in a state where the map display screen shown in FIG. 2B is displayed (that is, a state where the user is gazing at the map M). You can scroll in the direction. Further, since the button B and the pointer P are not displayed, in the state shown in FIG. 2B, the user moves the display position to be the map M and is not the pointer P, and the button B is not the operation target in this state. Can be recognized. Further, by displaying the compass C and the address display unit A together with the map M, the user can recognize the address of the displayed map M and the orientation in the map M.

  FIG. 2C shows a map display screen that is displayed when the viewpoint of the user exists in the address display unit A. As shown in FIG. 3B, a map M as a related object belongs to the group G2 to which the address display unit A belongs as a representative object. Further, as shown in FIG. 3B, a button B, a compass C, and a pointer P correspond to objects that do not belong to the group G2. Therefore, on the map display screen shown in FIG. 2C, the address display unit A and the map M are displayed, and the button B, the compass C, and the pointer P are transparent (not displayed).

  The user performs a swipe operation on the touch pad 41 in a state in which the map display screen illustrated in FIG. 2C is displayed (that is, a state in which the user is gazing at the address display unit A). Can be scrolled in a desired direction. In addition, since the button B, the compass C, and the pointer P are not displayed, the user can recognize that the object whose display position is to be moved is the map M and not the pointer P in the state shown in FIG. 2C. Further, since the pointer P is not displayed, the address display unit A can make the user recognize that it is not an operation target by the pointer P. In addition, since the button B and the pointer P are not displayed, the user can recognize that the button B is not an operation target in this state.

  FIG. 2D shows a map display screen that is displayed when the viewpoint of the user exists on the button B. As shown in FIG. 3B, a compass C, an address display unit A, and a pointer P belong as related objects to the group G3 to which the button B belongs as a representative object. As shown in FIG. 3B, a map M corresponds to an object that does not belong to the group G3. Therefore, on the map display screen shown in FIG. 2D, the button B, the compass C, the address display unit A, and the pointer P are displayed. Since the map M is an object linked to the third layer which is the lowest layer, the map M is displayed on the lowest layer in a gray scale state.

  The user desires the pointer P by performing a swipe operation on the touch pad 41 in a state where the map display screen shown in FIG. 2D is displayed (that is, a state where the user is gazing at the button B). It can be moved to the position. In addition, since the map M is displayed by changing from a color display state to a gray scale, the user can recognize that the object whose display position is to be moved is the pointer P and not the map M. Further, by displaying the button B and the pointer P, the user can recognize that the pointer P can be operated together with the button B.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, as long as an object with a viewpoint in the display screen and an object related to the object are displayed with higher visibility than other objects. Various embodiments can also be adopted. For example, the display system 10 may be applied to various systems and general-purpose computer systems. The display system 10 may be a system realized by a plurality of devices (for example, a client and a server). The display system 10 is not limited to the configuration mounted on the vehicle.

  Furthermore, at least a part of the viewpoint detection unit 21a and the display control unit 21b configuring the display system 10 may be divided into a plurality of devices. For example, the viewpoint detection unit 21 a may be realized by a control unit in the line-of-sight detection sensor 42. Of course, a part of the configuration of the above-described embodiment may be omitted, and the processing order may be changed or omitted.

  The viewpoint detection unit only needs to be able to detect the viewpoint of the user, and various configurations can be employed. For example, as in the above-described embodiment, the line of sight is specified by specifying the movement of the user's eyes based on the output of the camera that captures the user's eyes, and the intersection of the line of sight and the previously specified display screen It is possible to adopt a configuration that regards as a starting point. The number of eyes to be detected may be one or two, but in order to improve accuracy, it is preferable that the number of eyes to be detected is two. The viewpoint when the eyes of two eyes are specified may be statistically specified from each viewpoint specified based on the eyes of each eye, or the viewpoint is specified based on the bias by the dominant eye. Also good. Furthermore, the viewpoint may be specified at least on the display area visually recognized by the user.

  The display control unit can display the first object having a viewpoint and the second object related to the first object on the display unit with higher visibility than the first object and the third object other than the second object. As long as various configurations can be adopted. The object corresponding to the second object may be singular or plural. Further, the object corresponding to the third object may be singular or plural.

  In the above embodiment, a representative object and other objects are defined in each group that is grouped in advance according to relevance, and an example in which some objects can belong to a plurality of groups has been described. However, each object may be grouped according to relevance, and each object may belong to any one group. In this case, it can be said that the other object belonging to the group to which the object having the viewpoint belongs is the second object. Further, it can be said that the object belonging to the group other than the group to which the object having the viewpoint belongs is the third object.

  Moreover, various definitions are possible for the relationship between objects. For example, an object group that is determined in advance as being capable of inputting an instruction in the same instruction input stage (instruction input mode) may be treated as being related to each other. In addition, when the user can operate (or refer to) the first object, if the user can refer to it in his / her field of view, the object that is estimated to increase convenience is treated as being related to the first object. May be. Alternatively, object types (button object, background object, etc.) may be determined in advance, and objects of the same type may be treated as being related to each other. Alternatively, the objects displayed on the screen may be associated with one of the display layers in advance, and the objects associated with the same display layer may be treated as being related to each other. When an operation or input related to one object is performed, information that may be necessary for the operation or input may be treated as related when displayed on the other object.

  Further, the first object and the second object may be displayed in any manner as long as they are displayed with higher visibility than the third object, that is, displayed in a state that is easy for the user to visually recognize. Visibility can be expressed in various scales, but “visibility of first object ≧ visibility of second object> visibility of third object” or “visibility of second object ≧ visibility of first object> It is only necessary to satisfy the relationship of “visibility of the third object”. In addition to making the first object and the second object non-transparent and making the third object transparent, for example, at least one of the brightness and saturation of the first object and the second object is more visible than the third object. You may employ | adopt the structure which changes and displays in the direction which becomes relatively high. Further, for example, the hues of the first object and the second object may be set to a hue that can attract the user's attention more easily than the hue of the third object. Further, for example, a configuration may be adopted in which the thickness of a line constituting a frame or character included in the first object and the second object is displayed in a state thicker than the thickness of the line included in the third object. Further, for example, the lines included in the first object and the second object may be a solid line, and a part of the lines included in the third object may be omitted (for example, a broken line). In the case of transmission, the transmittance may be less than 100% instead of complete transmission.

  Also, for example, the area of the object when a certain object becomes the first object is S1, the area of the object when the object becomes the second object is S2, and the area when the object becomes the third object If the area of the object is S3, the display area of the object may be controlled so that S1 ≧ S2> S3.

  Further, for example, the first object and the second object may be blinked and the third object may be lit.

  In addition, a display part may be comprised by the single display and may be comprised by the some display.

  Furthermore, when the viewpoint moves from the first object to the outside of the first object and into the related area related to the first object, the display control unit visually recognizes the first object and the second object higher than the third object. You may display by sex. In this case, even if the user removes the viewpoint from the first object, the user can easily recognize the second object together with the first object as long as the viewpoint exists in the related area. The related area may be an area adjacent to the first object or the second object, or may be an area separated from the first object or the second object. In addition, the position, shape, and area of the related area of the first object may be fixedly determined in advance or may vary according to some parameter.

  The related area may be defined as an area that exists until a predetermined time elapses after the viewpoint moves outside the first object. In this case, even if the user removes the viewpoint from the first object, the user can easily recognize the second object together with the first object within a predetermined time. Note that the position, shape, and area of the related region may vary as the elapsed time after the viewpoint moves outside the first object increases within the predetermined time.

  For example, the related area may be an area that is set on the entire map display screen until a predetermined time (for example, 1 second) elapses after the viewpoint moves outside the button B. For example, the user moves the viewpoint to the address display unit A after adjusting the viewpoint to the button B1, and then moves the viewpoint to the button B6. After the viewpoint is out of the button B1, the viewpoint is moved to the button B6. If the time until the return is less than the predetermined time, the object may be displayed in the same manner as when the viewpoint is present on the button B1. In this case, since the buttons B1 to B6 are not hidden even if the user simply removes the viewpoint from the button B1 for a moment, the viewpoint can be easily moved to the button B6.

  Further, the related area may be defined as an area existing within a predetermined distance from the first object. In this case, even if the user removes the viewpoint from the first object, the user can easily recognize the second object together with the first object as long as the viewpoint exists within a predetermined distance from the first object. For example, the predetermined distance may be set to a distance that can absorb a viewpoint detection error. Note that the predetermined distance may be the same value for all objects, or may be a different value depending on the type of the object, the size of the object, and the like.

  For example, an area 100 illustrated in FIG. 5A is an example of an area set as a related area of the button B. A region 100 indicates a range in which the distance from each of the buttons B1 to B6 is a predetermined distance. For example, after the user has adjusted the viewpoint to the button B1, even if the viewpoint is out of the button B1, if the viewpoint exists in the area 100, the group G3 (see FIG. 3B) may be displayed, and only the map M may be displayed in a gray scale state.

  Further, the related area may be defined as an area between the first object and the second object. The situation where the viewpoint moves from the first object to the area between the first object and the second object, that is, the situation where the viewpoint moves between two or more related objects (including coming and going). Yes, it can be assumed that the user is comparing the related objects. In this case, even if the user removes the viewpoint from the first object, the user can easily recognize the second object together with the first object as long as the viewpoint exists in the area between the first object and the second object. The area between the first object and the second object is an area that is estimated to have a high possibility of including the locus of movement of the user's viewpoint when the viewpoint is moved from the first object to the second object. For example, it may be defined as a region connecting the first object and the second object in a straight line.

  For example, the related area may be set between related objects as shown in areas 101 to 105 in FIG. 5B. For example, when the user focuses on the button B1 and then aligns the viewpoint sequentially with the buttons B2 to B6, if there is a viewpoint in the areas 101 to 105, the same manner as when the viewpoint exists on the button B You may make it display an object. In this case, it is possible to prevent the map M from frequently switching between color display and gray scale display when the viewpoint moves between related objects.

  As the definition of the related area, any of the above definitions may be adopted, definitions other than the above may be adopted, or a plurality of these may be adopted in combination.

  Furthermore, as in the present invention, a method of displaying an object having a viewpoint in the display screen and an object related to the object with higher visibility than other objects can be applied as a program or a method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle, and include various aspects. It is a waste. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention can be realized as a recording medium for a program for controlling the system. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.
