[Figure 4A] This is a diagram (part 1) showing the flow of the display method performed by the in-vehicle display device. [Figure 4B] This is a diagram (part 2) showing the flow of the display method performed by the in-vehicle display device. [Figure 5] This diagram shows an example of touch operation. [Figure 6] This figure shows the animation for generating icons. [Figure 7]This diagram shows an icon bouncing off the edge of the display surface on the screen. [Figure 8] This diagram shows an animation where an icon moves from the first display to the second display. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings. The configurations of the following embodiments are illustrative, and the present invention is not limited to the configurations of these embodiments.

[0010] <Device configuration> Figure 1 is a block diagram showing the configuration of an in-vehicle display system (hereinafter also simply referred to as the system) 100 equipped with an in-vehicle display device 30 according to this embodiment, and Figure 2 is a diagram showing the arrangement of displays 10 and 20 provided in the driver's seat and passenger seat, respectively.

[0011] The system 100 comprises multiple displays 10, 20 and an in-vehicle display device 30 that controls these displays 10, 20. The multiple displays 10, 20 are arranged side by side in the left-right direction. Display 10 is mainly used by the driver and is located in the center of the dashboard in the left-right direction. Display 10 is also called a CID (Center Information Display) 10. Display 20 is mainly used by the passenger sitting in the front seat and is located on the left side of the dashboard in the left-right direction, i.e., in front of the passenger seat. Display 20 is also called a PID (Passenger Information Display) 10.

[0012] FIG. 3 is a diagram showing the configuration of the displays 10 and 20. The displays 10 and 20 include a display element 41 that displays an image in response to a video signal, a touch panel 42 disposed so as to overlap the display surface of the display element 41, and a ToF (Time of Flight) sensor 43. The display element 41 is a display means such as an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display, and displays an image in response to the video signal received from the in-vehicle display device 30. Not limited to this, the display element 41 may be any configuration capable of displaying an image, such as a head-up display that projects an image onto a screen.

[0013] The touch panel 42 uses the surface on which the images of the displays 10 and 20 are displayed, that is, the surface facing the occupant side, as an operation surface. The touch panel 42 is, for example, a capacitance-type touch panel that requests a touch operation on the displays 10 and 20 based on a change in capacitance when, for example, an occupant's finger or the like touches the operation surface. The touch panel 42 has a coordinate system with two orthogonal axes (X-axis, Y-axis) defined within the operation surface (plane), and detects the contact position of the occupant as coordinates in this coordinate system (hereinafter also referred to as position information). Further, the touch panel 42 detects a change in the contact position every unit time, and inputs information on the contact position and its change to the in-vehicle display device 30 as a detection result. Note that the touch panel 42 is not limited to the capacitance method, and may be a resistive film method, an ultrasonic surface acoustic wave method, or an optical method. The touch panel 42 is one form of a detection unit that detects a touch operation.

[0014] The ToF sensor 43 detects a gesture operation performed by the occupant without the occupant contacting the displays 10 and 20. The ToF sensor 43 detects, for example, the occupant's gesture by using the occupant's hand or arm as an object to be dealt with and detecting the distance to the hand or arm and its change in three-dimensional coordinates. The ToF sensor 43 is one form of a detection unit that detects a gesture operation. The detection unit that detects a gesture operation is not limited to the ToF sensor 43, and may be a camera, a three-dimensional scanner, or the like.

[0015] In the example of FIG. 3, the displays 10 and 20 are provided with both a detection unit (touch panel 42) for detecting a touch operation and a detection unit (ToF sensor 43) for detecting a gesture operation, but a configuration including only one of them may also be used. Further, the detection unit for detecting a gesture operation may be provided in the in-vehicle display device 30.

[0016] The in-vehicle display device 30 is an information processing device (computer) having a control unit 301, a storage unit 302, an input / output interface (IF) 303, and a communication IF 304 that are mutually connected by a connection bus 310. Further, the in-vehicle display device 30 may be a so-called ECU (Electronic Control Unit).

[0017] The control unit 301 controls the entire in-vehicle display device, and is composed of, for example, a processor such as a CPU (Central Processing Unit) or MPU (Micro Processing Unit), and a main storage device (main memory). The control unit 301 is also referred to as a controller. The control unit 301 is not limited to a configuration including a single processor, and may have a multi-processor configuration. Further, a single control unit 301 connected by a single socket may have a multi-core configuration. The main storage device is used as a work area, a storage area for programs and data, and a buffer area for communication data of the control unit 301. The main storage device includes, for example, a Random Access Memory (RAM), or a combination of a RAM and a Read Only Memory (ROM). The main storage device is a storage medium in which programs and data are cached by the processor and used as a work area.

[0018] The memory unit 302 is an auxiliary storage device that stores programs executed by the control unit 301, operation setting information, and the like. The memory unit 302 is not limited to an internal storage device built into the in-vehicle display device 30, but may also be an external storage device such as an external storage device or a NAS (Network Attached Storage). The memory unit 302 may be, for example, an HDD (Hard-disk Drive) or These include SSDs (Solid State Drives), EPROMs (Erasable Programmable ROMs), flash memory, USB memory sticks, and memory cards.

[0019] The input / output IF303 is an interface for inputting and outputting data with peripheral devices. For example, the input / output IF303 can input and output data with devices such as a disk drive that reads data from storage media such as CDs and DVDs, an operation unit that receives user input, and displays 10 and 20. The input / output IF303 may also input and output data with devices such as a tuner that receives radio and television broadcast waves, a reader / writer that reads and writes data to storage media such as memory cards, a microphone, a speaker, and a detection unit that detects gesture operations.

[0020] The communication IF304 is an interface that communicates with other devices via a communication line. The communication IF304 communicates with external data servers or other devices, for example, using a wireless communication method. The communication IF304 may also send and receive data and control signals to and from the detection unit that detects gesture operations via a priority network such as CAN or a wireless telephone line.

[0021] In the in-vehicle display device 30, the control unit 301 functions as a processing unit that executes predetermined information processing by running an application program (computer program). However, even if at least a part of the processing of each of the above processing units is provided by a DSP (Digital Signal Processor), ASIC (Application Specific Integrated Circuit), etc. That's fine. Also, at least a part of each of the above processing units may be a dedicated LSI (large-scale integration) such as an FPGA (Field-Programmable Gate Array) or other digital circuit. Furthermore, the in-vehicle display device 30 may be configured to include analog circuits in at least a portion of each of the above-mentioned processing units.

[0022] In the example shown in Figure 1, the displays 10 and 20 and the in-vehicle display device 30 are provided separately, but the in-vehicle display device 30 may be provided integrally with either the displays 10 or 20.

[0023] <Display method> Figures 4A and 4B show the flow of the display method performed by the in-vehicle display device 30. The control unit 301 of the in-vehicle display device 30 starts the processing shown in Figures 4A and 4B when the power is turned on or when it receives a start instruction. After the processing starts, the in-vehicle display device 30 repeatedly executes the processing shown in Figures 4A and 4B until the power is cut off or it receives a stop instruction.

[0024] In step S10, the control unit 301 determines whether or not it has detected the first operation on either of the displays 10 or 20, which are provided for the driver's seat and the passenger seat of the vehicle, respectively. The control unit 301 also identifies the display 10 or 20 on which the first operation was performed as the first display, and the display 10 or 20 on which the first operation was not performed as the second display. That is, if the driver performs the first operation on CID 10, CID 10 becomes the first display and PID 20 becomes the second display. Similarly, if the passenger in the passenger seat performs the first operation on PID 20, PID 20 becomes the first display and CID 10 becomes the second display. In this way, CID 10 and PID 20 can each be either the first display or the second display, and can exchange operations with each other.

[0025] The first operation is an operation to transfer an operation performed on the first display to the second display, and is a predetermined touch operation or a predetermined gesture operation. A predetermined touch operation is, for example, an operation in which a finger touches the operation surface of the first display and draws a circle, that is, an operation in which a ball is rolled and made into a ball with the fingertip. However, the first operation is not limited to this, and may be an operation in which multiple fingers (preferably 3 to 5 fingers) touch the operation surface and move the fingertips closer together (pinch in), or an operation in which multiple fingers touch the operation surface and move the fingertips closer together while rotating them. Figure 5 is a diagram showing an example of a touch operation. Figure 5(A) shows the movement trajectory 61 when an operation is performed in which a finger touches the operation surface and draws a circle. The control unit 301 may determine that the first operation has been performed if the movement trajectory 61 is not a perfect circle but is roughly round, as shown in Figure 5(A). Figure 5(B) shows the movement trajectory 62 when four fingers touch the operation surface and an operation is performed in which the fingertips are brought closer together. Figure 5(C) shows the movement trajectory 63 when three fingers touch the operating surface and rotate their fingertips to bring them closer together. Gesture operations include, for example, the operations shown in Figures 5(A) to (C) without touching the first display. Gesture operations may also include operations such as clenching an open hand, bringing a clenched fist closer to the operating surface, or rolling a ball of dough with both hands.

[0026] The first operation should be one that is not used for any other operation on the operation screen where the first operation is performed, but it is preferable that the operation be one that allows the user to visualize the shape of the icon (for example, spherical) that will be generated in response to the first operation.

[0027] In step S10, if the control unit 301 determines that the result is negative, it terminates the processing shown in Figures 4A and 4B. If the result is positive (if the first operation is detected), it proceeds to step S20.

[0028] In step S20, the control unit 301 performs the first display before the first operation is performed. The content displayed on (i) (hereinafter also referred to as the operation screen) is reduced in size and deformed to generate an icon for operation handover, which is then displayed on the first display. Figure 6 shows the animation for generating the icon. Figure 6(A) shows the operation screen 45 before the first operation is performed. Figure 6(B) shows the state immediately after the first operation is performed, as shown by the movement trajectory 61, where the operation screen 45 is a package that has begun to shrink toward the location where the first operation was performed. Figure 6(C) shows the process of the operation screen 45 shrinking, and Figure 6(D) shows the generated icon 46. In this embodiment, the icon 46 is an object that resembles a sphere. By making the icon 46 a sphere, the control unit 301 enables intuitive handover of processing, as if throwing the icon 46 like a ball. Furthermore, the icon 46 is not limited to a sphere (spherical), but may be in other shapes such as a capsule, envelope, box, or paper airplane.

[0029] In step S30, the control unit 301 determines whether a second operation has been detected for the icon 46 on the first display. Here, the second operation is a flick operation on the first display. The second operation may also be a flick operation that is started while the icon 46 is being touched.

[0030] If the determination in step S30 is negative, the control unit 301 proceeds to step S40 and determines whether the time elapsed since the first operation was performed or since the icon 46 was generated (elapsed time) exceeds a predetermined value. If the determination in step S40 is positive, the control unit 301 erases the icon 46 and terminates the process shown in Figures 4A and 4B. On the other hand, if the determination in step S40 is negative, the control unit 301 returns to step S30.

[0031] If the result in step S30 is positive, the control unit 301 proceeds to step S50 and displays an animation on the first display showing the icon 46 moving in the direction of the flick. Steps S30 and S40 for detecting the second operation are not mandatory and may be omitted. For example, after displaying the icon in step S20, the control unit 301 may proceed to step S50 and display an animation of the icon moving. In this case, the direction of the second display relative to the first display is predetermined, and after step S20, the control unit 301 may display an animation of the icon moving towards the second display.

[0032] In step S60, the control unit 301 determines whether the icon 46, by moving in the direction of the flick, has hit one of the four sides of the display surface of the first display that is on the side of the second display (the target side). In Figure 2, if CID 10 is the first display, the target side is the left side 10L.

[0033] If the determination in step S60 is negative, that is, if the icon 46, by moving in the direction of the flick, hits an edge in a direction without a second display (an unintended edge), the control unit 301 proceeds to step S70 and displays an animation of the icon 46 bouncing off that edge. Figure 7 shows the state in which the icon 46 has bounced off an edge of the display surface on the display 10. In the example in Figure 7, the icon 46 generated at position 51 is flicked in the direction of arrow 52, ​​bounces off edge 10U and stops at position 53. At this time, the angle (exit angle) θ2 when the icon 46 bounces off edge 10U and moves away from that edge may be displayed to be the same angle as the angle (incident angle) θ1 when it moves from the initial position 51 towards edge 10U. Alternatively, the icon 46 that has bounced off the edge may slow down and stop after traveling a predetermined distance. Not limited to this, the icon 46 after bouncing may be erased after traveling a predetermined distance and redisplayed at its original position. Furthermore, the animation of icon 46 bouncing may include not only the movement of icon 46, but also visual effects such as the area near where icon 46 hits glowing, or the area vibrating, rippling, or indenting. Furthermore, when icon 46 is deflected, a predetermined sound (alarm sound) may be output from the speaker. After step S70, the control unit 301 returns to step S30.

[0034] On the other hand, if the determination in step S60 is positive, that is, if the icon 46 hits (reaches) the side 10L (Figure 2) of the second display in the direction of the flick, the control unit 301 proceeds to step S80.

[0035] In step S80, the control unit 301 determines whether the operation to be handed over via icon 46 can be performed on the second display. For example, if the operation to be handed over can only be performed on the first display and not on the second display, the control unit 301 makes a negative determination. In addition, if the occupant using the second display is watching television broadcasts or movies and does not want to perform the operation to be handed over via icon 46 (hereinafter also referred to as the handover operation), or if they are concentrating on driving and do not want to perform the handover operation, the handover operation can be disabled. For example, if the occupant performs an operation on the second display that is not eligible for handover, the information that the handover operation is not eligible is registered in the storage unit 302. If this information that the handover operation is not eligible is registered, the control unit 301 makes a negative determination in step S80.

[0036] If the determination in step S80 is negative, the control unit 301 proceeds to step S90 and displays an animation in which the icon 46 bounces off the side 10L (Figure 2) in the direction of the second display. The animation in which the icon 46 bounces off is the same as in step S70. If the icon bounces off, the control unit 301 also displays on the second display an indication that the icon 46 has bounced off along the side of the first display in the direction of the first display. This indication that the icon 46 has bounced off may include the area near the side of the first display emitting light, or the side vibrating, rippling, or deforming as if the icon 46 has been embedded in it. This indication allows the second display to inform the crew that a handover request has been made, i.e., that the handover operation has been refused.

[0037] On the other hand, if the determination in step S80 is positive, the control unit 301 proceeds to step S100 and displays an animation of the icon 46 moving to the second display. Steps S60 to S90 are not mandatory and may be omitted. For example, the control unit 301 may display an animation of the icon moving on the first display in step S50 before proceeding to step S100. Figure 8 shows an animation of the icon 46 moving from the first display to the second display. Figure 8(A) shows the state in which the icon 46 generated at position 51 is flicked in the direction of arrow 54 and hits (reaches) edge 10L. Figure 8(B) shows the process in which the icon 46, after reaching edge 10L, moves without changing speed or direction, as if the icon 46 is moving outside edge 10L. Furthermore, the icon 46 that has gone outside edge 10L of the first display is gradually displayed from the edge of the second display as if it were entering from the right edge 10R of the second display. Figure 8(C) shows the state in which icon 46 disappears from the first display and appears on the second display, moves in the direction of arrow 55, and then stops at a predetermined position (for example, near the center) 56.

[0038] In step S110, the control unit 301 detects whether or not a third operation on the icon 46 displayed on the second display has been detected. Here, the third operation is, for example, an operation such as tapping or pinching out, which opens the icon 46 and performs the operation transfer.

[0039] If the determination in step S110 is positive, the control unit 301 proceeds to step S120 and, so that the operation performed on the first display before the first operation can be continued on the second display, the operation screen when the icon 46 was generated in step S20 is displayed on the second display. The information is displayed on the display. In this case, the control unit 301 may, for example, display an animation that expands the icons to form the operation screen in the reverse process of the process in S20 in which the operation screen was reduced and icons were generated. This allows the crew member using the second display to take over the operation that was being performed on the first display.

[0040] On the other hand, when icon 46 is sent from the first display to the second display, if the crew does not want to perform the handover operation using icon 46, they can return icon 46 to the first display by performing a second operation on icon 46 on the second display. For this reason, if the control unit 301 determines that step S110 is negative, it proceeds to step S130 and determines whether or not a second operation has been detected on icon 46 on the second display. Here, the second operation is a flick operation on the second display, which is the same operation as in step S30.

[0041] If the result in step S130 is positive, the control unit 301 proceeds to step S140 and displays an animation on the second display showing the icon 46 moving in the direction of the flick.

[0042] In step S150, the control unit 301 determines whether the icon 46, by moving in the direction of the flick, has hit one of the four edges on the display surface of the second display that is on the first display (the target edge). In Figure 1, if PID 20 is the second display, the target edge is the right edge 20R.

[0043] If the determination in step S150 is negative, that is, if the icon 46 hits an edge in the direction without the first display due to movement in the direction of the flick, the control unit 301 proceeds to step S160 and displays an animation of the icon 46 bouncing off that edge. The animation of the icon 46 bouncing off is the same as in step S70.

[0044] On the other hand, if the determination in step S150 is positive, that is, if the icon 46 hits (reaches) the side 20R (Figure 1) of the first display in a certain direction due to movement in the direction of the flick, the control unit 301 proceeds to step S170.

[0045] In step S170, the control unit 301 displays an animation of the icon 46 moving to the first display. The animation in step S170 is a reverse of the process in step S100 and Figure 8 where the icon 46 moves from the first display to the second display, that is, it represents the process of moving from the second display to the first display.

[0046] If the determination in step S130 is negative, the control unit 301 proceeds to step S180 and determines whether the time elapsed since the icon 46 was displayed on the second display (elapsed time) exceeds a predetermined value. If the determination in step S180 is negative, the control unit 301 returns to step S110. On the other hand, if the determination in step S180 is positive, the control unit 301 erases the icon 46 and terminates the process shown in Figures 4A and 4B. That is, if the third operation (S110) or the second operation (S130) is not performed after waiting for a predetermined time, the control unit 301 terminates the transfer process. Note that if these operations are not performed, the control unit 301 is not limited to terminating; it may also proceed to step S120, assuming that the user has accepted the operation, or to step S170, assuming that the user has returned the icon 46 to the other party.

[0047] <Effects of the Embodiment> (1) As described above, the in-vehicle display device 30 of this embodiment is simple and intuitive, such as sending the operation screen on the first display as icons 46 to the second display. The operation on the first display can be transferred to the second display. In this case, if the first and second displays are located in the driver's seat and the passenger seat, smooth transfer of operations between the driver's display and the passenger seat display becomes possible.

[0048] For example, if the driver is concentrating on driving and wants to hand over control to the CID10, the CID10 can be used as the primary display, and the icon 46 can be sent to the PID20 (secondary display), allowing for a smooth handover of control from the driver to the passenger. Also, if the driver does not know how to open the control screen, the PID20 can be used as the primary display, and the passenger can open the control screen on the PID20, transform it into the icon 46, and send it to the CID10 (secondary display), allowing for a smooth handover of control from the passenger to the driver.

[0049] (2) In the in-vehicle display device 30 of this embodiment, the first operation may be a touch operation on the first display or a gesture operation performed without contact with the first display. This allows the in-vehicle display device 30 of this embodiment to initiate a handover operation by a touch operation or a gesture operation. When the touch operation or gesture operation is an operation that visualizes the shape of the icon 46, the handover operation can be initiated intuitively.

[0050] (3) In the in-vehicle display device 30 of this embodiment, the icon 46 may be an object that resembles a sphere. This allows the in-vehicle display device 30 of this embodiment to intuitively initiate a handover operation by performing an operation that visualizes the shape of the icon 46, such as rolling it up.

[0051] (4) In the in-vehicle display device 30 of this embodiment, the content (operation screen) that was displayed on the first display before the first operation was performed may be reduced in size and transformed into icons 46. This allows the in-vehicle display device 30 of this embodiment to easily pass on the operation screen.

[0052] (5) In the in-vehicle display device 30 of this embodiment, the control unit 301 may detect a second operation on the first display, and when the second operation is detected, it may display an animation on the first display showing the icon 46 moving from the first display to the second display, and an animation on the second display showing the icon 46 moving from the first display to the second display. This makes it easy to see which user is passing the operation to which user.

[0053] (6) In the in-vehicle display device 30 of this embodiment, the second operation is a flick operation on the first display, and the control unit 301 may display an animation in which the icon moves in the direction of the flick operation. This allows the in-vehicle display device 30 of this embodiment to pass operations through simple and intuitive operations such as flick operations.

[0054] (7) In the in-vehicle display device 30 of this embodiment, when the icon 46 moves in the direction of the flick and hits one of the four sides of the display surface of the first display that does not have a second display, an animation may be displayed in which the icon 46 bounces off that side. This configuration ensures that the in-vehicle display device 30 of this embodiment cannot transfer the icon 46 when it has not been sent to the second display, that is, it only transfers the icon 46 when it has been sent to the second display, and appropriate transfer It is possible to perform a transfer operation.

[0055] (8) In the in-vehicle display device 30 of this embodiment, when the icon 46 moves in the direction of the flick, an animation may be displayed in which the icon 46 moves to the second display when it hits one of the four sides of the display surface of the first display that is in the direction of the second display. This enables the in-vehicle display device 30 of this embodiment to perform an appropriate transfer operation.

[0056] (9) In the in-vehicle display device 30 of this embodiment, if the handover operation is not operable on the second display, an animation may be displayed in which the icon 46 bounces back without moving to the second display. This makes it easy to understand that the handover operation cannot be performed by making the icon 46 bounce back in the in-vehicle display device 30 of this embodiment.

[0057] (10) In the in-vehicle display device 30 of this embodiment, when the icon 46 is deflected, the second display may display an indication that the icon 46 has been deflected along a certain edge of the first display. This allows the in-vehicle display device 30 of this embodiment to clearly indicate to the occupant using the second display that the handover operation cannot be performed by a predetermined indication such as illumination or vibration of the edge.

[0058] (11) In the in-vehicle display device 30 of this embodiment, when the icon 46 is deflected, the first display may illuminate the side of the second display in a certain direction. This allows the in-vehicle display device 30 of this embodiment to clearly indicate to the occupant using the first display that the handover operation cannot be performed by illuminating or vibrating that side, or by any other predetermined indication.

[0059] <Other> The configurations and combinations thereof in the embodiments described above are examples, and additions, omissions, substitutions, and other modifications are possible as appropriate, without departing from the spirit of this disclosure.
