JP 2002-215284 A JP 08-297543 A Japanese Patent Laid-Open No. 05-298057 Japanese Patent Laid-Open No. 10-105365 International Publication No. 2005/101172 JP 2003-271310 A JP 2006-302084 A

  In the configurations disclosed in Patent Document 1 and Patent Document 2, a specific selection area including a pointer in the display screen is highlighted and displayed based on an operation input to the mouse. Therefore, when the operator who has actually started the operation turns his / her line of sight on the display screen prior to the start of input, the selected area is not yet highlighted. According to the above, since it is difficult for the operator to perceive the selection area, the position of the pointer included in the selection area may not be quickly grasped by the operator. Therefore, in the configurations of Patent Document 1 and Patent Document 2, a situation may occur in which the visibility of the selected image cannot be ensured.

  On the other hand, in the configuration disclosed in Patent Document 3, since the selection area is emphasized based on the absence of input to the mouse for a certain period of time, it is assumed that the operator has turned his / her line of sight to the display screen before starting the input. However, the operator can perceive the selected area displayed with emphasis. However, even if the operator does not intend to operate, the selection area is emphasized when there is no input to the mouse for a certain period of time. Therefore, when an operator who does not intend to operate directs his / her line of sight to the display screen, the highlighted selection area may cause the operator to feel uncomfortable. At this time, the display design is impaired.

  The present invention has been made in view of the above problems, and an object thereof is to provide a display control system capable of improving the visibility of a selected image without impairing the display design.

In order to achieve the above object, the invention according to claim 1 is an input means for inputting an operation by an operator, a button image associated with a predetermined function, and a selection image for selecting a button image, Display means for displaying the image on the display screen, control means for controlling the position where the selected image is displayed on the display screen according to the input to the input means, and whether there is an operation intention of the operator who starts the operation of the input means A determination means for determining whether or not the determination means emphasizes and displays a specific selection area including the selected image on the display screen based on the determination that the determination means has an operation intention . The control means stops displaying the selected image on the display screen when there is no preset time input to the input means, and the emphasizing means is determined by the determining means after the control means stops displaying the selected image. Control If the intention is determined that there, and displays the selected image to the stop the display position, and display control systems that is characterized in that highlighted the selected area including the selected image.
According to a second aspect of the present invention, an input means for inputting an operation by an operator, a button image associated with a predetermined function, and a selection image for selecting the button image are displayed on a display screen. A display unit; a control unit that controls a position where the selected image is displayed on the display screen according to an input to the input unit; and a determination unit that determines whether there is an operation intention of the operator who starts the operation of the input unit Based on the determination that the determination means determines that there is an operation intention, the highlight means for highlighting and displaying a specific selection area including the selected image on the display screen and the range including the eyes of the operator are photographed. An image acquisition unit that acquires the captured image, and an image analysis unit that analyzes a line-of-sight direction of the operator's line of sight from the captured image acquired by the image acquisition unit. Based on the fact that the line-of-sight direction to be analyzed is directed to the display screen, it is determined that there is an intention to operate, and the emphasizing unit ends emphasis of the selected region at a preset time. Let it be a display control system.
Furthermore, the invention according to claim 6 displays on the display screen an input means for inputting an operation by the operator, a button image associated with a predetermined function, and a selection image for selecting the button image. A display unit; a control unit that controls a position where the selected image is displayed on the display screen according to an input to the input unit; and a determination unit that determines whether there is an operation intention of the operator who starts the operation of the input unit Based on the determination that the determination means has the operation intention, the highlight means for highlighting and displaying a specific selection area including the selected image on the display screen, and the approach of the tangible object to the input means are detected. Proximity detection means, and speed detection means for detecting the speed of movement of the tangible object detected by the proximity detection means, the determination means is a proximity detection means for the tangible object approaching the input means Therefore, it is determined that there is an operation intention based on the detection, and the emphasizing unit shortens the time for emphasizing the selected region as the speed of movement of the tangible object detected by the speed detecting unit increases. And a display control system.

According to these inventions, the operator for inputting an operation input unit, when it is determined by the determining means operation intended there to start the operation of the input means includes a selected image among the display screen A specific selection area is highlighted. Therefore, even if the operator who actually started the operation turns his / her line of sight to the display screen prior to the start of input, the operator perceives the selected area highlighted on the display screen. it can. As described above, the operator can quickly grasp the position of the selected image included in the selected area, so that the visibility of the selected image on the display screen is improved.

  On the other hand, when it is determined by the determination means that there is no intention to operate, the selection area is not emphasized by the enhancement means. Therefore, even if an operator who does not intend to operate has his / her line of sight on the display screen, a situation in which the highlighted selection area causes an uncomfortable feeling to the operator can be avoided. As described above, the display design of the display screen is hardly damaged.

Therefore, the display control system can improve the visibility of the selected image without impairing the display design .
In addition, as in the second aspect of the invention, by analyzing a captured image obtained by capturing a range including the eyes of the operator by the image analysis unit, the line-of-sight direction toward the line of sight of the operator can be detected. Therefore, even in the configuration in which it is determined that there is an operation intention based on the line-of-sight direction analyzed by the image analysis unit being directed to the display screen, the highlighted selection area is displayed on the display screen before the operation is started. It is possible to prompt the operator who looks at the user to quickly grasp the position of the selected image.
In addition, in the above configuration, the enhancement of the selected region ends at a preset time. Therefore, even when an operator who does not intend to operate directs his / her line of sight to the display screen, the uncomfortable feeling caused to the operator by highlighting the selected region is suppressed. Thus, even if the operation intention is determined based on the line-of-sight direction of the operator, the effect of improving the visibility of the selected image is exhibited without impairing the display design.

According to the first and third aspects of the present invention , when the input to the input means is not performed for a preset time, the line of sight is directed to the display screen by stopping the display of the selected image on the display screen. A situation in which the selected image causes troublesomeness for an operator who does not intend to operate can be avoided. Therefore, the display design of the display screen is less likely to be impaired.
In addition, when it is determined that there is an operation intention, the selected image is displayed again at the position where the display is stopped. Therefore, the operator can surely and quickly grasp the position of the selected image by looking at the position where the display is stopped in order to continue the operation performed before the display of the selected image is stopped. Therefore, the visibility of the selected image is further improved.

According to the fourth and sixth aspects of the present invention, an operator who intends to start an operation on the input unit causes a part of the body such as one hand to approach the input unit. Therefore, based on the detection result of the proximity detection unit that detects the approach of a tangible object such as a hand to the input unit, the determination unit has an intention to operate before starting the input while ensuring high certainty. Can be determined. As described above, the operator can surely and quickly grasp the position of the selected image included in the highlighted selection area even if the user looks at the display screen before starting the input. Therefore, the effect of improving the visibility of the selected image on the display screen is more easily exhibited.

Generally, an operator who wants to quickly perform an operation of selecting a button image based on a selected image moves one hand toward the input means at a higher speed. Therefore, in the inventions described in claims 5 and 6, the time for emphasizing the selected region is shortened as the moving speed of the tangible object approaching the input means increases. With the configuration described above, the highlighting of the selected area by the highlighting means is completed earlier as the operator tries to perform the operation of selecting the button image as soon as possible. Therefore, the enhancement of the selection area exhibits an effect of assisting the operator in grasping the position of the selected image, and makes it difficult to prevent the operator from selecting the button image. Therefore, the display control system can ensure the operability at the time of selecting the button image while improving the visibility of the selected image.

In the invention according to claim 7 , the display control system further includes contact detection means for detecting contact of the tangible object with the input means, and the determination means detects that the tangible object in contact with the input means is detected by the contact detection means. Based on the above, it is determined that there is an operation intention.

  According to the present invention, an operator who intends to start an operation on the input means brings one hand or the like into contact with the input means. Therefore, based on the detection result of the contact detection unit that detects the contact of the tangible object with the input unit, the determination unit determines that the operator has an intention to operate before starting the input while ensuring high certainty. can do. As described above, the operator can surely and quickly grasp the position of the selected image included in the highlighted selection area even if the user looks at the display screen before starting the input. Therefore, the effect of improving the visibility of the selected image on the display screen is more easily exhibited.

In the invention according to claim 8 , the selected image includes an instruction image portion that indicates the button image in the selected state by being displayed so as to overlap the button image, and the highlighting means displays the instruction image portion. A region to be emphasized is selected as a selection region.

  According to the present invention, since the area where the instruction image portion is displayed is directly emphasized as the selection area, the operator can more easily and quickly grasp the position of the instruction image portion. Thus, the visibility of the selected image can be further improved by having the instruction image portion emphasized as the selection region.

According to the ninth aspect of the present invention, the selection image includes a frame-shaped image portion that indicates the button image in the selected state by being displayed along the outer edge of the button image, and the enhancement unit includes the frame-shaped image. An area surrounded by the portion is emphasized as a selection area.

  According to the present invention, since the area surrounded by the frame-shaped image portion is emphasized as the selection area, the area of the selection area in the display screen can be ensured to be large. Therefore, the effect of causing the operator to quickly grasp the position of the selected image by emphasizing the selected area is more easily exhibited. Thus, the visibility of the selected image can be further improved by having the frame-like image portion that defines the outer edge of the selected region.

According to a tenth aspect of the present invention, the enhancement means emphasizes the selected region by enlarging and displaying one of the selected image and the button image selected by the selected image. As in the present invention, the selected image and the button image selected by the selected image are displayed in an enlarged manner, so that they can stand out on the display screen. Therefore, one of the selection image and the button image surely exerts an effect of enhancing the selection region including the selection image, and makes it easy for the operator to grasp the position of the selection image.

Further, the invention described in claim 11 is characterized in that the emphasizing means emphasizes the selected region by enlarging the brightness difference between the region excluding the selected region and the selected region on the display screen. As in the present invention, if the brightness difference between the area excluding the selected area and the selected area is enlarged, the position where the selected area is located on the display screen can be surely conspicuous. Therefore, the selected area whose brightness is higher than that of the surrounding area can attract the operator's line of sight, and can exert an effect of promptly grasping the position of the selected image included in the selected area.

Furthermore, the invention described in claim 12 is characterized in that the emphasizing means emphasizes the selected region by moving the position of the button image selected by the selected image. If the position of the button image selected by the selected image is moved as in the present invention, the position of the button image in the selected state on the display screen, and thus the position of the selected image can be quickly grasped by the operator.

In addition, in the invention according to claim 13 , the highlighting means displays on the display screen the button images excluding the selected button image selected by the selected image among the plurality of button images displayed on the display screen. By stopping, the selected region is emphasized. When a plurality of button images are displayed on the display screen as in the present invention, the display on the display screen may be stopped except for the selection button image selected by the selection image. By displaying one button image, the position of the selected button image in the selected state on the display screen, and thus the position of the selected image, can be quickly grasped by the operator.

  As described above, according to various enhancement methods of selected areas and combinations thereof, the visibility of the selected image is further improved.

(First embodiment)
A display control system 100 according to the first embodiment of the present invention shown in FIG. 1 includes an operation device 20, a navigation device 40, and the like. As shown in FIG. 2, the display control system 100 is installed in the vehicle interior with the display screen 60 of the navigation device 40 facing the driver's seat. The display control system 100 displays an image as shown in FIG. 3 on the display screen 60 in a normal display mode when an operation by an operator such as a driver is input to the operation device 20. First, based on FIG. 3, the detail of the image displayed on the display screen 60 is demonstrated.

  The image displayed on the display screen 60 includes a plurality of icons 65, a pointer 61, and a focus 63. Each icon 65 is associated with a predetermined function. Each icon 65 is formed in, for example, a rectangular shape, and includes a character indicating an associated function and a figure reminiscent of the function. When any one of the plurality of icons 65 arranged on the display screen 60 is selected, the navigation device 40 performs a process associated with the icon 65.

  The pointer 61 is a selection image for selecting the icon 65. The pointer 61 has an arrow shape and is displayed so as to overlap the icon 65, thereby pointing to the icon 65 in the selected state. The icon 65 moves on the display screen 60 in response to an operation input to the controller device 20 (see FIG. 1). In addition, the icon 65 is stopped from being displayed on the display screen 60 when there is no preset time input to the controller device 20. The focus 63 has a rectangular shape and is displayed along the outer edge of the icon 65 to indicate the button image in the selected state.

  Next, the configuration of the display control system 100 will be described in detail with reference to FIGS. The operation device 20 and the navigation device 40 are connected to a Controller Area Network (CAN) bus 10 and can exchange information with each other. The CAN bus 10 is a transmission path used for data transmission between in-vehicle devices in an in-vehicle communication network formed by connecting a plurality of in-vehicle devices mounted on a vehicle.

  The operation device 20 is provided at a position away from the navigation device 40, and is a device for remotely operating the position of the pointer 61 (see FIG. 3) of the display screen 60. The operating device 20 includes a proximity sensor 33 as a characteristic configuration in addition to the touch pad 31 and the operation control unit 35.

  The touch pad 31 is formed in a rectangular flat plate shape, and is disposed on a center console that can be easily reached by an operator. The touch pad 31 is an input interface through which an operation by the operator is input. In the touch pad 31, the surface with which an operator's finger | toe etc. contact is formed of the insulating sheet. Inside the touch pad 31 covered with the insulating sheet, electrodes extending along the X direction and electrodes extending along the Y direction are arranged in a grid pattern. These electrodes are connected to the operation control unit 35.

  The operation control unit 35 includes a processor that performs various arithmetic processes, a flash memory that stores programs used for the arithmetic processes, a RAM that functions as a calculation work area, and the like. In addition, the operation control unit 35 is connected to the CAN bus 10, thereby connecting to a communication interface that communicates with an in-vehicle device such as the navigation device 40 via the CAN bus 10, and the touch pad 31 and the proximity sensor 33. A plurality of sensor interfaces.

  The operation control unit 35 measures a potential of each electrode through a sensor interface connected to the touch pad 31 by executing a predetermined program. When the operator's finger touches the surface of the touch pad 31, an electric charge is stored between the electrode and the finger with the insulating sheet interposed therebetween. The operation control unit 35 detects the coordinates where the operator's finger is in contact with the touch pad 31 from the measured change in potential of each electrode. Then, the operation control unit 35 causes the navigation device 40 to acquire the coordinate information by outputting the detected coordinate information to the CAN bus 10.

  The proximity sensor 33 is arranged on the center console side by side with the touch pad 31. The proximity sensor 33 is configured to detect a tangible object existing in a predetermined space, and is specifically provided as a detection unit that detects the approach of the operator's hand. The proximity sensor 33 used in the first embodiment detects, for example, the distance from the sensor 33 to the detected object by detecting the infrared light reflected by the detected object such as an operator's hand by detecting infrared rays. Detect the position of an object. When the proximity sensor 33 detects a detected object, the proximity sensor 33 outputs position information as a detection result to the sensor interface of the operation control unit 35. The position information is acquired by the navigation device 40 by being output to the CAN bus 10 by the operation control unit 35.

  The navigation device 40 includes a navigation control unit 55, a display control unit 53, and a liquid crystal display 51. The navigation control unit 55 includes a processor that performs various arithmetic processes, a flash memory that stores programs and the like used for the arithmetic processes, and a RAM that functions as a calculation work area. In addition, the navigation control unit 55 has a communication interface that communicates with an in-vehicle device such as the operation device 20 through the CAN bus 10 by being connected to the CAN bus 10.

  The display control unit 53 includes a processor that performs a drawing process of an image displayed on the display screen 60, a flash memory that stores a program and image data used for the drawing process, a graphic RAM that functions as a drawing work area, and the like. It is constituted by. The display control unit 53 is communicably connected to the navigation control unit 55 via a bus or the like, and draws an image based on a command signal from the navigation control unit 55. In addition, the display control unit 53 has an output interface that sequentially outputs the drawn image data to the liquid crystal display 51.

  The liquid crystal display 51 is a dot matrix display that realizes color display by controlling a plurality of pixels arranged on the display screen 60. The liquid crystal display 51 displays an image on the display screen 60 based on the image data sequentially acquired from the display control unit 53. Thus, the liquid crystal display 51 provides various information to the driver by various images displayed on the display screen 60.

  The navigation control unit 55 and the display control unit 53 described above control the display positions of the pointer 61 and the focus 63 on the display screen 60 according to the input to the touch pad 31 as shown in FIGS. More specifically, the navigation control unit 55 instructs the display control unit 53 to display the coordinates of the pointer 61 and the icon 65 surrounded by the focus 63 based on the coordinate information acquired from the operation control unit 35. The display control unit 53 draws the pointer 61 at the coordinates instructed by the navigation control unit 55 and the focus 63 surrounding the icon 65 instructed by the control unit 55. As described above, the positions of the pointer 61 and the focus 63 on the display screen 60 are moved according to the contact position of the operator's finger on the touch pad 31.

  The display control system 100 described so far temporarily switches the display mode of the display screen 60 from the above-described normal display mode to the highlighted display mode as shown in FIG. First, details of the image displayed on the display screen 60 in the highlight mode will be described with reference to FIG.

  In the highlight display mode, a specific selection area 67 including the pointer 61 in the display screen 60 is highlighted. In the first embodiment, as shown in FIG. 4A, the area where the pointer 61 is displayed on the display screen 60 is the selection area 67. Specifically, the pointer 61 in the highlight mode is emphasized by being enlarged and displayed in a display color with higher saturation than the pointer 61 (see FIG. 3) in the normal display mode. .

  Then, as shown in FIGS. 4B and 4C, the pointer 61 is gradually reduced in size while being gradually reduced in size. In this way, the display mode of the pointer 61 once highlighted is returned to the display mode of the pointer 61 in the normal display mode, as shown in FIG. 4D. By returning from the highlight display mode to the normal display mode as described above, the highlight of the selection area 67 ends at a preset time.

  The switching to the highlight mode described above is performed based on the determination of the navigation control unit 55 that the operator has an intention to operate the touch pad 31. Hereinafter, the process of switching between the normal display mode and the highlight display mode will be described in detail with reference to FIG. The processing shown in FIG. 5 is performed by the navigation control unit 55 based on the fact that information that notifies the start of the engine is acquired from the information output to the CAN bus 10.

  In S101, a command signal instructing the start of display on the display screen 60 is output to the display control unit 53, and the process proceeds to S102. As a result, the display control unit 53 starts drawing an image and outputs drawing data to the liquid crystal display 51 to start displaying information on the display screen 60. In S102, a command signal instructing the start of operation of the controller device 20 is output to the operation control unit 35, and the process proceeds to S103. As a result, the operation control unit 35 starts acquiring coordinate information from the touch pad 31 and position information from the proximity sensor 33 and outputting the information to the navigation control unit 55. Note that the order of S101 and S102 may be changed.

  In S <b> 103, it is determined whether there is an operation intention of the operator who starts the operation of the touch pad 31 based on whether the detected object approaching the touch pad 31 is detected by the proximity sensor 33. If the position information of the detected object cannot be acquired from the proximity sensor 33 in S103, it is determined that the operator does not intend to operate, and the process proceeds to S110. On the other hand, if the position information of the detected object can be acquired from the proximity sensor 33 in S103, it is determined that the operator has an intention to operate, and the process proceeds to S104.

  In S104, the moving speed is detected for the detected object moving toward the touch pad 31 from the change in the position information of the detected object acquired from the proximity sensor 33, and the process proceeds to S105. In S105, based on the stored correlation data, the switching time to the highlight mode is set from the moving speed detected in S104, and the process proceeds to S106. In the correlation data used in S105, a correlation between the moving speed of the detected object and the switching time is defined in advance. Based on this correlation data, the time for emphasizing the selection area 67 is set shorter as the moving speed of the detected object increases.

  In S106, based on the determination that there is an operation intention in S103, a command signal instructing switching to the highlight mode is output to the display control unit 53, and the process proceeds to S107. As a result, the display control unit 53 switches the display mode of the display screen 60 from the normal display mode (see FIG. 3) to the highlight display mode (see FIG. 4), and highlights the pointer 61 for the time set in S105. .

  In S107, it is determined whether or not the operation intention determined in S103 is continued. Specifically, it is determined that the operation intention is continued based on whether the detected object is detected by the proximity sensor 33 or an operation to the touch pad 31 is input. If the position information is not acquired from the proximity sensor 33 and the coordinate information is not acquired from the operation control unit 35 in S107, it is determined that the operator's operation intention is lost, and the process proceeds to S110. On the other hand, when any information of position information and coordinate information is acquired in S107, it is determined that the operator's operation intention is continued, and the process proceeds to S108.

  In S108, a command signal instructing to continue displaying the icon 65 is output to the display control unit 53, and the process proceeds to S109. Thereby, the display control unit 53 continues drawing the pointer 61 to the drawing data to be output to the liquid crystal display 51. Thus, the pointer 61 continues to be displayed on the display screen 60 after returning to the normal display mode.

  In S109, as in S107, it is determined whether or not the operation intention is continued based on the position information and the coordinate information. If it is determined in S109 that the operator's intention to operate has been lost, the process proceeds to S110. On the other hand, when it is determined in S109 that the operator's operation intention is continued, the process returns to S108.

  In S <b> 110 when it is determined in S <b> 103, S <b> 107, and S <b> 109 that the operator does not intend to operate, a command signal instructing to stop displaying the icon 65 is output to the display control unit 53, and the process proceeds to S <b> 111. As a result, the display control unit 53 stops drawing the pointer 61 to the drawing data output to the liquid crystal display 51. Thus, the pointer 61 disappears from the display screen 60. At this time, the display control unit 53 stores the position where the drawing of the pointer 61 is stopped.

  In S111, it is determined whether or not the ignition of the vehicle has been turned off based on the information output to the CAN bus 10 that notifies the stop of the engine. If it is determined in S111 that the ignition is turned off, the process is terminated. On the other hand, if it is determined in S111 that the ignition is on, the process returns to S103. The display control unit 53 that has acquired again the command signal for instructing the display of the icon 65 in the processes of S103 to S111 repeated in this way again returns to the position where the drawing of the pointer 61 stored in the previous S110 is stopped. Start drawing. As described above, when it is determined again that there is an operation intention after the display of the pointer 61 is stopped, the pointer 61 is highlighted and displayed again at the position where the display is stopped.

  In the first embodiment described so far, when the navigation control unit 55 determines that the operator has an intention to operate, the pointer 61 set as the selection area 67 is displayed with emphasis. Therefore, even if the operator who actually tried to start the operation of the touch pad 31 turns his line of sight to the display screen 60 before starting the input, the operator highlights the display screen 60 and displays it. Can be perceived. As described above, since the position of the pointer 61 can be quickly grasped by the operator, the visibility of the pointer 61 on the display screen 60 is improved.

  On the other hand, when the navigation control unit 55 determines that there is no operation intention, the pointer 61 is not emphasized. Therefore, even when an operator who does not intend to operate directs his / her line of sight to the display screen 60, a situation in which the emphasized pointer 61 causes a sense of discomfort to the operator can be avoided. As described above, the display design of the display screen 60 is not easily damaged.

(Second embodiment)
The second embodiment of the present invention shown in FIGS. 6 to 9 is a modification of the first embodiment. In the display control system 200 of the second embodiment shown in FIG. 6, the operation device 220 includes a joystick 231 and a contact sensor 233 in addition to the operation control unit 35. The joystick 231 is an input interface corresponding to the touch pad 31 (see FIG. 2) of the first embodiment, and is installed in the center console as shown in FIG. The joystick 231 can be tilted in the front-rear direction and the left-right direction by the operation of the operator. As shown in FIG. 6, the joystick 231 is connected to the sensor interface of the operation control unit 35, and outputs the tilt angles in the front-rear direction and the left-right direction to the operation control unit 35.

  As shown in FIGS. 6 and 7, the contact sensor 233 is configured to detect contact of a tangible object with the joystick 231. Specifically, the contact sensor 233 is a detection unit that detects contact of an operator's hand or the like. It is provided on the surface. The contact sensor 233 is, for example, a pressure sensor, and detects the pressure applied to the joystick 231 by the operator. The contact sensor 233 is connected to the sensor interface of the operation control unit 35, and outputs a detection result indicating that there is a contact object to the operation control unit 35 when a contact object to the joystick 231 is detected.

  The operation control unit 35 executes a predetermined program to acquire the tilt angle of the joystick 231 in each direction and convert it into two-dimensional coordinate information. And the operation control part 35 makes the navigation control part 55 acquire by outputting the converted coordinate information and the detection result acquired from the contact sensor 233 to the CAN bus 10. FIG.

  Next, details of the image displayed on the display screen 60 in the second embodiment will be described with reference to FIGS. 6 and 8. When no operation is input to the joystick 231 in the normal display mode, a plurality of icons 65 are displayed on the display screen 60 as shown in FIG. 8A. At this time, the display of the pointer 61 and the focus 263 (see FIG. 8C) is stopped.

  When the mode is switched to the highlight mode from the above state, as shown in FIG. 8B, the pointer 61 and the focus 263 are displayed, and the area surrounded by the focus 263 is highlighted as the selection area 267. In the second embodiment, the brightness of the area 268 excluding the selection area 267 (hereinafter referred to as “non-selection area”) on the display screen 60 is reduced. In this way, the brightness difference between the selected area 267 and the non-selected area 268 is enlarged, so that the selected area 267 is highlighted.

  Then, when a preset time elapses after switching to the highlight mode, the decrease in brightness of the non-selected area 268 is stopped as shown in FIG. 8C. In this way, by returning from the highlight display mode to the normal display mode, the highlight of the selection area 267 ends at a preset time.

  The process of switching from the normal display mode to the highlight mode described above is performed by the control unit 55 based on the determination of the navigation control unit 55 that the operator has an intention to operate the joystick 231. Hereinafter, the display mode switching process in the second embodiment will be described in detail with reference to FIG. In the process performed in the second embodiment, processes corresponding to S104 and S105 (see FIG. 5) of the first embodiment are omitted. Therefore, the time during which the highlight mode is switched is constant as the preset time. Further, S201, S202, S204, S206, S208, and S209 of the second embodiment are substantially the same as S101, S102, S106, S108, S110, and S111 (see FIG. 5) of the first embodiment.

  In S203, based on the detection result of the contact sensor 233, it is determined whether or not there is an operation intention of the operator who starts the operation of the joystick 231. In S203, when the detection result that there is a contact is not obtained from the contact sensor 233, it is determined that the operator does not intend to operate, and the process proceeds to S208. On the other hand, when the detection result indicating that there is a contact object can be acquired from the contact sensor 233 in S203, it is determined that the operator has an intention to operate, and the process proceeds to S204.

  In S <b> 205 and S <b> 207, it is determined that the operation intention is continued based on either that the contact object is detected by the contact sensor 233 or that an operation to the joystick 231 is input. In these steps, when the detection result from the contact sensor 233 is not acquired and the coordinate information is not acquired from the operation control unit 35, it is determined that the operator's intention to operate is lost. On the other hand, when any information of the detection result and the coordinate information is acquired in these steps, it is determined that the operator's operation intention is continued.

  Also in the second embodiment described so far, the display control system 200 can prevent the operator from feeling uncomfortable while making it easy for the operator to quickly grasp the positions of the pointer 61 and the focus 263. Therefore, the display control system 200 can improve the visibility of the pointer 61 and the focus 263 without impairing the display design.

  In addition, an operator who wants to start operating the joystick 231 first brings one hand into contact with the joystick 231. Therefore, based on the detection result of the contact sensor 233 that detects contact with the joystick 231, the navigation control unit 55 determines that the operator has an operation intention before starting the input while ensuring high reliability. can do. As described above, the operator can surely and quickly grasp the positions of the pointer 61 and the focus 263 included in the highlighted selection area 267 even if the operator looks toward the display screen 60 before starting the input. . Therefore, the effect of improving the visibility of the pointer 61 and the focus 263 is more easily exhibited.

In S304, the line-of-sight direction of the operator is analyzed, and based on the analyzed line-of-sight direction, it is determined whether there is an operation intention of the operator who starts the operation of the touch pad 31. Specifically, the driver's eyes, particularly the outline of the pupil, is extracted from the captured image 371 acquired in S303. And a driver | operator's gaze direction is analyzed from the outline shape of the pupil reflected on the picked-up image 371. FIG. In S304, if the analyzed operator's line-of-sight direction is pointing to an area outside the display screen 60, it is determined that the operator has no intention to operate, and the process proceeds to S309. On the other hand, if the analyzed operator's line-of-sight direction is directed to the display screen 60 in S304, it is determined that the operator has an intention to operate, and the process proceeds to S305.

  In S306, it is determined whether or not an operation on the touch pad 31 has actually started. If the coordinate information is not acquired from the operation control unit 35 in S306, it is determined that the operator's operation has not been started, and the process proceeds to S309. On the other hand, when the coordinate information is acquired in S306, it is determined that the operation of the operator is started, and the process proceeds to S307.

  In S308, it is determined whether or not the operation intention is continued. In S308, when the operator's line-of-sight direction is away from the display screen 60 and no coordinate information is acquired from the touch pad 31, it is determined that the operator's intention to operate is lost, and the process proceeds to S309. . On the other hand, in S308, when the line-of-sight direction is facing the display screen 60 or when the coordinate information is acquired, it is determined that the operator's operation intention is continued, and the process returns to S307. .
