Specification

Display device and operation setting method in the same device

Technical field

[0001] The present invention provides display means for simultaneously displaying an image having a first viewing angle and an image having a second viewing angle different from the first viewing angle, and providing an operation surface on a display screen. The present invention relates to a display device and an operation setting method in the device.

Background art

[0002] A so-called dual-view display liquid crystal display panel that simultaneously displays an image having a first viewing angle and an image having a second viewing angle different from the first viewing angle controls the viewing angle of the panel By doing so, different information and contents are displayed on the left and right at the same time.

Therefore, when a dual-view liquid crystal is used for the display monitor of the navigation device, the navigation screen can be viewed from the driver's occupant and the DVD (Digital Versatile Device) cinema screen can be viewed from the passenger's occupant. Different LCDs can display different visuals on the left and right.

[0003] The dual-view liquid crystal can be combined with an operation surface (touch panel) arranged on the front of the display panel to form a display input device, such as an icon menu for displaying an occupant on the dual-view liquid crystal. By touching, communication with the navigation device itself becomes possible. For this reason, the touch panel is installed in the navigation device as a human interface with excellent operability separately from the console and the remote control, and has come into the market as a touch panel-mounted navigation device.

[0004] By the way, in a conventional navigation device equipped with a dual-view liquid crystal using a touch panel, a screen viewed from the driver side (hereinafter referred to as the driver side screen) and a screen viewed from the passenger side (hereinafter referred to as the assistant). The icon of the same menu structure is displayed on the seat side screen). However, although a menu that allows all items to be selected is displayed on the passenger side screen, a menu that includes some operation restriction items is displayed on the driver side screen, which is different from other items. Displayed in color or design.

[0005] The navigation device main body allows each occupant to perform a touch operation even during dual view display. It is necessary to perform display control by discriminating whether or not the touch panel operation key is effective for the operation of the shifted image so that the desired content can be viewed.

However, it is very difficult to determine which occupant has performed the operation.For example, it is necessary to operate the switching switch every time it is operated. This is preferable because it increases the complexity of the operation and impairs the intuitive touch operation and the advantages of the touch panel.

[0006] For this reason, conventionally, the touch panel is arranged in such a manner that the touch panel overlaps with the viewer A touch-dedicated area and the viewer B touch-dedicated area! / Depending on the operation area. There has been proposed a display device that can discriminate between operations (for example, see Patent Document 1 and Patent Document 2).

Patent Document 1: Japanese Patent Laid-Open No. 2005-71286 (paragraph “0011”, FIG. 1)

Patent Document 2: Japanese Patent Laid-Open No. 2005-284592 (paragraphs “0010” to “0016”, FIG. 2)

[0008] However, according to the techniques disclosed in Patent Document 1 and Patent Document 2 described above, the operation area is simply separated and assigned to each viewer (occupant). If Viewer A mistakenly operates the operation area assigned to Viewer B, it will be mistaken for the operation of Viewer B, and the display on Viewer B will be unintended.

The present invention has been made to solve the above-described problems, and simultaneously displays an image having a first viewing angle and an image having a second viewing angle different from the first viewing angle. When the dual view is displayed, operation means that can be operated are assigned to the driver side passenger and the passenger on the passenger side, and the operation of the operation means by each occupant is determined by the screen having the first viewing angle and the second view above. Obtaining a display device and an operation setting method for the same device by avoiding a situation in which an operation by one occupant unintentionally affects the other screen by determining whether the screen with corners is effective for! / With the goal.

FIG. 1 is a block diagram showing an internal configuration of a touch panel mounting type navigation apparatus as a display apparatus according to Embodiment 1 of the present invention.

The touch panel-mounted navigation device shown in FIG. 1 has a control unit (control unit) 10 as a core, a vehicle state detection unit (vehicle state detection unit) 11, a seating state detection unit (sitting state detection unit) 12, The navigation control unit 13, the operation unit (operation means) 14, the storage unit 15, the display unit 16, the audio control unit 17, the TV tuner control unit 18, the air conditioner control unit 19, and the DVD drive 20 Composed.

[0015] The vehicle state detection unit 11 is a vehicle state based on information obtained from ECU (electronic control unit) and various sensors such as key position, shift position, parking brake, and vehicle speed signal. Here, in particular, it is detected whether or not the vehicle is in a stopping state while the vehicle is running and is output to the control unit 10.

The seating state detection unit 12 also acquires information from the seating sensors installed under the seats of the driver seat and the passenger seat, detects the seating state of the occupant, and outputs the information to the control unit 10. On the other hand, the navigation control unit 13 is a sensor installed in each part of the vehicle, for example, a GPS (Global Positioning System) receiver 131, an angle sensor 132, a distance sensor 133, or a map storage device 134. Using the external communication device 135, etc., the current position of the vehicle is grasped, and the navigation device main body function is realized in cooperation with the control unit 10, such as route search and destination guidance.

The operation unit 14 is a remote controller (infrared remote controller or a handheld remote controller), voice recognition, hard key, touch panel, etc., and the navigation by the driver side passenger or passenger side passenger operating these operation means. It functions as a man-machine interface indicating the occupant's will to the control unit 13 or 10. The remote control is taken in via the remote control signal receiver 141, the voice recognition is taken in via the voice input part 142 and the voice recognition part 143, the hard key 144 is taken in directly, and the touch panel is taken in via the touch panel 145 and the touch panel drive part 145. Each signal is output to the control unit 10. In each embodiment of the present invention, the operation unit 14 described above is used as an operation means assigned to each of the driver's seat side passenger and the passenger's side passenger during the dual view display.

[0017] The storage unit 15 preliminarily stores various setting information, and is also used as a work area when the control unit 10 executes a built-in program.

Further, as described above, the display unit 16 includes the liquid crystal display panel 162 capable of dual view display for performing separate display on the driver's seat side screen and the passenger seat side screen (screen viewed from different viewpoints). The display unit 16 includes a video generation unit 161 that generates video content and button icons under the control of the control unit 10 described above, and a dual-view liquid crystal panel that displays a dual-view display of the video generated by the video generation unit 161. 162 and a backlight 163 that projects a color filter installed on the dual-view liquid crystal panel 162 from behind to make the color display clear.

[0018] The control unit 10 determines the operation state based on the input information from each unit, and also controls the entire display control. Here, in the dual view display, the operation by the operation unit 14 is detected and operated. Determines whether the screen viewed from the occupant (driver's seat screen) and the screen viewed from the passenger occupant (passenger side screen) is effective, and controls the determined effective screen. It also has a function as a control means. Reference numerals 17, 18, and 19 denote an audio control unit, a TV tuner control unit, and an air conditioner control unit, respectively, all of which are controlled by the control unit 10 and defined as button icons for audio playback and TV tuner playback. Execute each of the air conditioner control.

FIG. 2 is a block diagram showing a functional development of the internal configuration of the control unit 10 shown in FIG.

If the control unit 10 is expanded by function, a setting UI (User Interface) providing unit 101, a setting information acquisition unit 102, an operation means allocation control unit 103, an operation restriction control unit 104, and a normal operation screen control unit 105, a driver-seat-side operation screen control unit 106, a passenger-seat-side operation screen control unit 107, and a display control unit 108.

[0020] The setting UI providing unit 101 generates display information for assigning operation means, setting the operation depending on the sitting state of the passenger on the passenger seat, and permitting or prohibiting the touch operation, and generates the driver side passenger and passenger side passenger. It has a function to provide a user interface that prompts input. It also provides a user interface that allows the driver side passenger or passenger seat passenger to which the touch panel 145 is assigned to set the acceptance of the touch operation to the permitted state or the prohibited state.

Based on the user interface provided by the setting UI providing unit 101, the setting information acquiring unit 102 captures setting information input by the driver side passenger or the passenger side passenger, and the operation unit assignment control unit 103 and the operation restriction control unit. Output to 104.

[0021] The operation means assignment control unit 103 is assigned to each of the driver side passenger and the passenger side passenger on the basis of the setting information taken in via the setting information acquisition unit 102, and performs the operation by the operation means. The operation restriction control unit 104 is controlled by determining whether the operation of the operation means by each occupant is valid for the driver side screen or the passenger side screen. In addition, the operation restriction control unit 104 detects the operation by the operation means (remote control, voice, hard key, touch panel) assigned to the driver side passenger and the passenger side passenger, and displays the driver side screen and the passenger seat. The status to allow or prohibit the acceptance of touch operations according to the setting information from the transfer side occupant assigned to the touch panel 145 or the passenger on the front passenger side, in addition to determining which side screen is valid It also has a control function.

[0022] For example, the operation restriction control unit 104 forcibly accepts the touch operation based on the vehicle state information output by the vehicle state detection unit 11 when the touch operation is in the reception-prohibited state. It has a function to set to the enabled state and force the touch operation to the reception prohibited state when dual display is resumed. Further, the operation restriction determination unit 104 outputs the passenger seat side output by the seating state detection unit 12 when the operation of the touch panel 145 is assigned to the passenger on the passenger seat side and the touch operation is set to the reception prohibition state. Based on the passenger's seating information, the dual view display is forcibly canceled and the function to set the touch operation to the reception-permitted state is also provided.

[0023] It should be noted that the normal operation screen control unit 105 reflects the operation contents on both the driver side screen and the passenger side screen, and the driver side operation screen control unit 106 operates only on the driver side screen. Reflecting the contents of the operation, the passenger seat side operation screen control unit 107 reflects the operation contents only on the passenger seat side screen and outputs them to the display control unit 108.

The display control unit 108 is responsible for overall display control of the liquid crystal panel 162 of the display unit 16 based on the display information generated by the control unit 10, and also includes a normal operation screen control unit 105, a driver side operation screen control unit 106, Display control is executed based on information according to the operation content output by each of the passenger-side operation screen control units 107.

[0024] The touch panel-mounted navigation device according to Embodiment 1 of the present invention is characterized in that the operation means are separated so that the driver side passenger and the passenger side passenger cannot use the touch operation at the same time. To be assigned to. At this time, a symbol indicating that the touch operation is currently prohibited, for example, an icon, is displayed on the screen of the passenger whose touch operation is prohibited.

Specifically, it is assumed that the touch panel 145 is assigned to the driver side passenger and the infrared remote controller is assigned to the passenger side passenger. At this time, a button icon for touch operation is displayed on the driver's seat side screen. At this time, the voice recognition including the touch operation of the touch panel 145 and the handle remote control operation are effective only for the driver side screen.

On the other hand, no button icon for touch operation is displayed on the passenger seat side screen. However, only infrared line remote control is effective on the passenger side screen. Hard key operation is also effective for! / And misalignment of the driver's side screen and passenger's side screen.

On the other hand, it is assumed that voice recognition or a handle remote control is assigned to the driver's seat side passenger, and touch panel 145 is assigned to the passenger's side passenger. At this time, the touch screen is displayed on the driver's screen. The tongue icon is reflected on the driver's side screen only for voice recognition and steering wheel remote control without being displayed. On the other hand, a button icon for touch operation is displayed on the passenger side screen. Therefore, touch operation and infrared remote control operation are effective only on the passenger side screen. Hard key operations are effective on both the driver's side screen and the passenger's side screen.

As a result, the driver's seat side occupant cannot perform the touch operation, so safety is ensured, and the passenger's seat side occupant can perform an intuitive operation by the touch operation.

[0027] Further, it is assumed that a voice recognition or steering wheel remote control is assigned to the driver side passenger and an infrared ray remote control is assigned to the passenger side passenger. In this case, the button icon for touch operation is not displayed on either the driver's side screen or the passenger's side screen. Voice recognition and handle remote control operations are reflected only on the driver side screen, and infrared remote control operations are reflected only on the passenger side screen. Hard key operations are effective on both the driver's side screen and the passenger's side screen.

As a result, the driver on the driver's seat cannot perform the touch operation, so safety is ensured. The passenger on the passenger side cannot perform a touch operation, but can perform an intuitive operation by selecting a button icon like the touch operation by infrared remote control operation.

[0028] It should be noted that the above-mentioned operation means are assigned to each of the driver side passenger and the passenger side passenger.

1S Set via a user interface provided by the touch panel mounted navigation device according to the first embodiment of the present invention.

For example, the driver's seat side occupant sets the operation means used on the driver's seat side during dual view display, such as hard key, touch panel, voice recognition, steering wheel remote control, infrared remote control, and performs dual display. If not, set the operation means used on the driver's seat side, such as hard key, touch panel, voice recognition, handle remote control, infrared remote control. In addition, the passenger on the passenger side sets the operation means used on the passenger side, such as hard keys, touch panel, voice recognition, and infrared remote control during dual view display, and is also performing dual display. If there is not, set the operation means used on the driver's seat side, such as hard key, touch panel, voice recognition, infrared remote control. In either the driver's seat or passenger's seat However, it is important that the operation means to be used does not overlap depending on whether or not the dual view display is medium

[0029] As shown in FIG. 2, the control unit 10 uses the GUI providing means 101 to prompt the setting input of the operating means used for each of the driver side passenger and the passenger side passenger, The setting information input by the passenger on the passenger side is taken in by the setting information acquisition unit 102 and supplied to the operation means allocation control unit 103.

The operation means allocation control unit 103 assigns the operation means to each other so that there is no duplication according to the setting information input and fetched so that the operation by the assigned operation means is reflected on the corresponding screen. Control. If there are duplications in the operation means, for example, assignment is determined according to the priority order that has been defined in advance, thereby avoiding duplication of settings by the driver side passenger and the passenger side passenger. Also, the operation method to be used will be monitored depending on whether dual view is being displayed or not.

[0030] On the other hand, in the touch panel-mounted navigation device according to Embodiment 1 of the present invention, the driver-side passenger or the passenger-side occupant assigned with the touch operation prohibits or permits the touch operation. Is possible. That is, only when a touch operation is necessary, the acceptance of the touch operation is permitted, and during the other periods, the acceptance of the touch operation is prohibited, and the touch operation is assigned! /. Consideration is given so that the operation will not be affected.

Note that the operation to perform “prohibition of touch operation acceptance” can be performed by an occupant who is not assigned a touch operation, so a setting method using a touch operation or a hard key is used. Do it!

On the other hand, it is necessary to prevent the operation for performing “touch operation acceptance permission” from being executed from the passenger side to whom the touch operation is assigned! Therefore, the prohibition state cancellation method is displayed on the screen corresponding only to the occupant side to which the touch operation is assigned, and the occupant must release the touch operation prohibition state by performing an operation based on the cancellation method. Is possible. As a method for canceling the touch operation prohibition state, a method using a touch operation,! / Other than the touch operation, or a deviation method may be used.

Here, in the method of performing the touch operation, the occupant side to which the touch operation is assigned is used. Only a button icon for canceling the prohibition of touch operation acceptance is provided, and the display position at this time is a random position each time. This is also a consideration to prevent occupants who are not assigned touch operation from guessing the button icon position. In order to display a random position button icon, a random number method may be considered.

[0032] In addition to the method performed by other than the touch operation, only the occupant side to which the touch operation is assigned displays a method for canceling the touch operation acceptance prohibition, for example, pressing a specific hard key. In addition, it is important that the method of canceling the operation is not always the same method, but is changed each time so that a passenger who is not assigned a touch operation cannot guess the release method.

Furthermore, the display of the method for canceling the touch operation acceptance prohibition state is displayed only when a specific operation force is performed for a certain period of time because it is highly likely that the operation will be obstructed if it is always displayed on the screen even when no operation is required. Other times shall be erased. Here, the specific operation may be touching the corresponding screen while the touch operation is prohibited, pressing a specific hard key, or the like.

FIG. 3 shows a state transition of the prohibition Z permission setting of the touch operation reception described above. In FIG. 3, if the state transition of the control unit 10 starts from the touch operation acceptance permission state (step ST31), an occupant who is assigned to use the touch panel 145, for example, passenger side passenger force passenger side By touching the “prohibit touch operation acceptance” button icon displayed on the screen, a transition to the “prohibit touch operation acceptance” state is made (step ST32).

Subsequently, by a specific operation, for example, a display start operation, a “touch operation acceptance permission” button icon or a touch operation acceptance prohibition release method is displayed on the passenger side screen (ST33). Here, the control unit 10 waits for the “touch operation acceptance permission” button icon to be operated or the touch operation acceptance prohibition release method being executed, and then transitions to the “touch operation acceptance permission” state of ST31. If the button icon is not operated for a certain period of time, the “Accept touch operation” button icon is deleted (ST34).

[0034] Furthermore, the touch panel mounted navigation device according to the first embodiment of the present invention can be provided with an operation limiting function.

If dual view display is canceled, there is no need to prohibit acceptance of touch operations. Therefore, if the dual display is canceled while the touch operation acceptance is prohibited, it is forcibly set to the “touch operation acceptance permitted” state, and then when the display is returned to the dual view display again, the “touch operation acceptance” is forcibly set. Can be set to “prohibited” state. Specifically, the touch panel-mounted navigation device according to Embodiment 1 of the present invention includes the vehicle state detection unit 11 and can determine whether the vehicle is traveling or stopped. When the navigation screen is displayed on both the passenger's side screens, it is possible to restrict the touch operation on the driver's side while driving and allow the touch operation while the vehicle is stopped. This can be expected to improve safety and convenience.

[0035] It should be noted that the button icon prepared as a user interface for the touch operation acceptance permission Z prohibition setting is any one of a fixed hard key, an arbitrary hard key, a touch operation (fixed position), and a touch operation (arbitrary position). Is selected and set. In addition, the display of permission settings is started by a hard key or touch operation. If the display of permission settings is always displayed, the selection is invalid. Further, the end of display of the permission setting is always displayed, or the display time is fixed as described above, and it is deleted by the time item.

[0036] Furthermore, according to the touch panel-mounted navigation device according to Embodiment 1 of the present invention, since the seating state detecting unit 12 is provided, the touch operation is assigned to the passenger on the passenger seat side. And when it is set to “Do not accept touch operation” status, when it is detected that there is no passenger in the passenger seat, dual display can be forcibly canceled and touch operation acceptance can be permitted. it can.

Note that the user interface prepared for setting the operation when there is no occupant in the passenger seat will automatically cancel the dual view display on the screen as if there were an occupant. This is done by setting the display.

FIG. 4 is a flowchart showing a specific operation of the control unit 10 described above. Hereinafter, the operation of the control unit 10 shown in FIGS. 1 and 2 will be described in detail with reference to the flowchart shown in FIG.

[0038] Here, the control unit 10 controls the setting UI providing unit 101 in advance to prompt the driver side passenger and the passenger side passengers to input the setting of the operating means to be used. ,Passenger seat It is assumed that the information on the use operation means input by the side occupant is taken in via the setting information acquisition unit 102.

In the example shown in FIG. 4, as operation means to be used for each occupant, the driver panel side occupant is assigned voice recognition and steering wheel remote control power, and the touch panel 145 is assigned to the passenger side occupant. The operation using the voice recognition, steering wheel remote control, and touch panel 145 according to each assignment according to the assignment is monitored to determine whether the driver side screen or the passenger side screen is effective, and the operation restriction control unit 104 Is controlled.

Operation restriction control unit 104 acquires vehicle state information indicating whether the vehicle is traveling or stopped from vehicle state detection unit 11 (step ST401). Here, it is determined whether or not dual view is being displayed by determining whether the vehicle is traveling or not. The operation restriction control unit 104 also acquires occupant seating information regarding the presence / absence of a passenger seat occupant from the seating state detection unit 12 (step ST402).

Next, based on the acquired vehicle state information and occupant seating information, the operation restriction control unit 104 determines whether or not the occupant is present in the passenger seat, and whether or not the liquid crystal display panel 162 is in real view display. Are determined respectively (steps ST403 and ST404).

[0040] Here, the operation restriction control unit 104 determines that, based on the vehicle state information and the occupant seating information, the dual view display is in progress and the passenger is present in the passenger seat (both step ST403 and step ST404 are "Yes"") Wait for input by operating means. If there is an operation with voice recognition or the handle remote control (step ST405 “Ye _S ”), the driver's side operation control unit 106 is activated, and the operation is reflected only on the driver's side screen for the display control unit 108. The display control is executed (step ST406).

On the other hand, when the operation is a touch operation other than voice recognition or the handle remote control (step ST407 “Yes”), the operation restriction control unit 104 activates the passenger seat side operation control unit 107 to display the display control unit 108. Display control is executed to reflect the operation only on the passenger side screen (step ST408).

[0041] When it is determined in step ST403 that there is no occupant in the passenger seat, the operation restriction control unit 104 determines whether or not the dual-view display medium force is used (step ST411), If the dual view is being displayed (step ST411 “Yes”), it is further determined whether or not forced release setting is input (step ST412). If the forced release setting is made (step ST412 “Yes”), the dual view display is canceled (step ST413), and the operations assigned to the driver side passenger and passenger side passenger are performed. Waiting for input by means (step ST409 “Yes”), activate normal operation screen control unit 105 and display control to reflect operation to display control unit 108 on each of driver's side screen and passenger's side screen Is executed (step ST410).

On the other hand, if it is determined in step ST412 that the forced release setting has not been made (step ST412 "No"), operation using the handle control remote control assigned to the driver's side passenger or voice recognition input (Step ST414 “Yes”), the driver side operation control unit 106 is activated, and the display control unit 108 is caused to execute display control that reflects the operation only on the driver side screen (step ST415).

That is, the operation restriction control unit 104 forcibly sets the touch operation to the reception-permitted state based on the vehicle state information output by the vehicle state detection unit 11 while the touch operation is in the reception-prohibited state. When the display resumes, the touch operation is forcibly set to the reception-prohibited state. In addition, when the operation of the touch panel 145 is assigned to the passenger on the passenger seat and the touch operation is set to the reception prohibition state, the seating information of the passenger on the passenger seat output by the seating state detection unit 12 is displayed. Based on this, the dual display is forcibly canceled and the touch operation is set to the acceptance-permitted state.

As a result, when the passenger is seated in the passenger seat and the dual display is released, all operations are reflected on both screens, and the passenger is not seated in the passenger seat and is forced during dual display. If the dual display release is set for, it is forcibly released. As a result, the touch operation of the driver side occupant becomes effective.

Note that the flowchart shown in FIG. 4 is realized by the controller 10 sequentially reading and executing a program recorded in a built-in ROM (not shown).

Here, a specific control example will be described. Figs. 5 to 7 show specific control examples when the touch operation is assigned to the driver's side occupant (Fig. 5), and when the touch operation is assigned to the passenger's side occupant (Fig. 6). Seat side occupant T Fig. 7 is a table that summarizes the actions in each of the cases where the operation is not assigned (Fig. 7).

In FIGS. 5 to 7, as (a), the operations in the vehicle running state and the stopped state are shown as the state 1 to the state 3 for the display contents on the driver side and the passenger side, Also, (b) shows the display contents in each state and the operation means for the driver side passenger and the passenger side passenger means at that time! / Speak.

First, description will be made with reference to FIG.
