  Hereinafter, modes for carrying out the present invention will be described. The description of the embodiment is an exemplification, and the present invention is not limited to the following description.

Embodiment 1
FIG. 1 is a schematic plan view of the in-vehicle user interface device, and FIG. 2 is a perspective view showing a display device and a motion sensor. The longitudinal direction of the vehicle 1 is taken as the X direction, the vehicle width direction as the Y direction, and the height direction as the Z direction. The same applies to the subsequent figures.

  As shown in FIG. 1, in a compartment 4 of the vehicle 1, there are two front seats 2 (2A, 2B) which constitute a front seat (driver's seat and front passenger seat) and two rear seats which constitute a rear seat. Sheets 3 (3A, 3B) are arranged.

  The front seat 2 is rotatably provided about a vertical axis (Z axis). That is, the front seat 2 is rotatably provided between a forward position facing the front of the vehicle and a rearward position facing the rear seat 3 facing the rear of the vehicle.

  The front seat 2 and the rear seat 3 are so-called motorized seats, and are provided with slide devices (not shown) that slide and move the seats in the front-rear direction of the vehicle 1 by an electric motor or the like. Further, the front seat 2 is provided with a rotation device (not shown) for rotating the seat by an electric motor or the like. The configurations of the slide device and the rotation device are not particularly limited, and an existing configuration may be adopted. Therefore, detailed description of the slide device and the rotation device is omitted.

  A user (hereinafter referred to as an occupant) seated on the front seat 2 can operate the slide device and the rotation device appropriately by operating a predetermined switch, and the front seat 2 can be arranged as desired. Further, an occupant seated on the rear seat 3 can operate the slide device appropriately by operating a predetermined switch to slide the rear seat 3 to a desired position in the longitudinal direction of the vehicle.

  The vehicle 1 is capable of completely automatic driving which does not require a driver. For this reason, not only the front seat 2B on the passenger seat side, but also the front seat 2A on the driver seat side is configured to be pivoted between the forward position and the facing position by the pivoting device.

  As shown in FIGS. 1 and 2, an on-vehicle user interface device 10 including a display device 30 and a motion sensor 40 is mounted in the passenger compartment 4.

  The display device 30 is a device that displays a stereoscopic image in space. As such a display device, a known device for displaying a stereoscopic image in space can be adopted.

  For example, it is possible to use a display device that displays an image in the air by spraying fog and using it as a screen and projecting an image on the screen.

  Besides, it is possible to use a display device which forms a stereoscopic image in the air by using a lens or a concave mirror. In addition, a display capable of displaying a two-dimensional image and a lens array in which microlenses are arranged in front of the display can be arranged, and a display device in which an image is formed in the air by the lens array can be used. In addition, a display capable of displaying a two-dimensional image, and a transmission type mirror array imaging element that realizes an imaging action by treating light incident on a minute mirror as one light beam and controlling those light beams by many mirrors A display device using a child can be used. Furthermore, it is possible to use a volume-type three-dimensional display in which light spots can be three-dimensionally arranged by scanning based on screen rotation and the like.

  In any display device, a stereoscopic image displayed in the air can be observed from all around.

  Such a display device 30 is disposed so as to be surrounded by the front seat 2 and the rear seat 3 substantially at the center of the passenger compartment 4. The display device 30 is arranged to display a stereoscopic image in the upper space. An area in which the display device 30 can display a stereoscopic image is referred to as a display area 31. Further, in the display area 31, three-dimensional coordinates (X, Y, Z) are defined, and three-dimensional coordinates can be specified to display a stereoscopic image.

  In the present embodiment, a rectangular parallelepiped area is a display area 31 between the respective seats in the passenger compartment 4 (between the front seat 2 and the rear seat 3). Therefore, the 3D image displayed in the display area 31 can be viewed regardless of whether the front seat 2 or the rear seat 3 is seated.

  The motion sensor 40 is a device for detecting the motion of the hand of the occupant, and specifically, is a device that emits infrared light and picks up the reflected light reflected by the object to be detected to form an image. is there. An area where the motion sensor 40 can detect the hand of the occupant is referred to as a detection area 41. The detection area 41 is an area including the display area 31. That is, when the occupant puts his hand in the detection area 41, the motion sensor 40 obtains an action of the hand as an image.

  Further, as shown in FIG. 3, the storage device 11, the control device 20 and the microphone 50 are mounted on the vehicle 1.

  The storage device 11 stores predetermined content. The content is various information related to the vehicle 1. For example, the names of on-vehicle devices, setting items related to the on-vehicle devices, and information on facilities around the vehicle 1 and on a route on which the vehicle 1 tries to travel.

Examples of on-vehicle devices include navigation systems, radios, audio devices, and air conditioners. In the case of a navigation system, examples of setting items related to in-vehicle devices include a route and a destination. Similarly, in the case of a radio, it is a volume or a radio station, and in the case of an air conditioner, it is an operation mode (heating, cooling, blowing, etc.), temperature and air volume. is there.
As described above, the storage device 11 stores various information on in-vehicle devices and contents on peripheral facilities.

  The contents are not limited to those stored in the storage device 11 mounted on the vehicle 1. The content may be stored on a remote storage device. In this case, a server device provided with a storage device storing content is provided to enable wireless communication with the vehicle 1. Then, when a keyword is transmitted from the vehicle 1 to the server device via wireless communication, the server device searches the storage device for content corresponding to the keyword, and transmits the content to the vehicle 1. Thus, the vehicle 1 may obtain content from the remote storage device 11.

  The control device 20 is an ECU (Electronic Control Unit), and includes a CPU, a ROM for storing and storing control programs, a RAM as an operation area of the control programs, an EEPROM for rewritably holding various data, peripheral circuits, and the like. It is configured to include an interface unit that takes an interface. The control device 20 is connected to each part of the vehicle 1 via an interface part, exchanges information with the respective parts, and controls each part.

  The control device 20 further includes a detection unit 21, a voice recognition unit 22, and a display control unit 23. These units are realized by the CPU of the control device 20 executing a control program.

  The detection unit 21 analyzes the image acquired from the motion sensor 40, and detects the position and movement of the occupant's hand. The position of the hand is, for example, three-dimensional coordinates based on the origin of the display area 31. The motion sensor 40 and the detection unit 21 correspond to motion detection means described in the claims.

  Since the detection of the position and movement of the hand based on the analysis of the image is a known technique, the detailed description is omitted, but the detection unit 21 can detect the following movement of the hand.

  For example, the detection unit 21 can detect the shape of a hand such as a hand in a held state, a hand in an open state, or a hand in a pointed state. In addition, it is possible to detect the orientation of a hand such as a horizontal hand or a vertical hand. Besides, the distance and the position from the motion sensor 40 can also be detected. Then, the detection unit 21 detects the movement of the hand from such a change in the state of the hand. For example, a flick operation, a slide operation, a point operation, and a pinch operation are determined as hand movements.

The flicking motion is a motion in which the fingertip is swung left and right or up and down around the wrist.
The sliding motion is a motion for moving the entire hand vertically and horizontally.
The point motion is a motion in which a part of the finger, for example, a forefinger is extended and the other finger is bent and the hand is moved vertically or horizontally.
The pinching motion is a motion in which the two fingertips approach or separate in a state where two fingers are stretched. The pinching operation in which two fingertips are close to each other is referred to as pinching-in operation, and the pinching operation in which two fingertips are separated from each other is also referred to as pinch-out operation.

  The voice recognition unit 22 analyzes the voice acquired from the microphone 50 and recognizes words and the like of the voice emitted by the occupant. Furthermore, the voice recognition unit 22 analyzes the voice acquired from the microphone 50, and detects the position of the source of the voice, that is, the position of the occupant. Such voice recognition and detection of the position of the occupant can be performed by a known voice analysis technology. The microphone 50 and the voice recognition unit 22 correspond to the occupant position detection means and the voice recognition means described in the claims. The occupant position detection means is not limited to such voice recognition. For example, the occupant position detection means may be a device that detects the position of the occupant by analyzing an image in a vehicle compartment captured by a camera.

  The display control unit 23 is an example of a display control unit that performs control of causing the display device 30 to display content as a stereoscopic image. The display control unit 23 reads the content from the storage device 11 and displays the content on the display device 30 in a data format that can be displayed by the display device 30.

  FIG. 4 is a view showing an example of a stereoscopic image representing content. 4A is a perspective view of the stereoscopic image A viewed from one side, and FIG. 4B is a perspective view of the stereoscopic image A viewed from the opposite side (the stereoscopic image A in FIG. FIG. 4C is a perspective view of the stereoscopic image B. FIG. The stereoscopic image A is an opaque (invisible on the opposite side) cube-shaped stereoscopic image, and the stereoscopic image B is a translucent (invisible on the opposite side) spherical stereoscopic image.

  Content is displayed on the stereoscopic image A and the stereoscopic image B. For example, as shown in FIG. 4A, on each surface on one side of the three-dimensional image A, new arrival information on a facility "OO land" and a peripheral map of the facility are displayed. Further, as shown in FIG. 4B, on each surface on the opposite side of the stereoscopic image A, the surrounding weather of the facility and the SHOP information (merchandise information) of the facility are displayed.

  As shown in FIG. 4C, in the stereoscopic image B, newly arrived information (a part of the characters wrap around on the back side and can be seen through from the front side) about the facility "○ ラ ン ド land" along the spherical surface. It is displayed.

  As described above, although the content is displayed on the stereoscopic image A and the stereoscopic image B, another content (such as a thumbnail image) for calling the content may be displayed. For example, although details will be described later, when the occupant touches the surface displayed as "map" of the stereoscopic image A, another stereoscopic image on which the map of "OO land" is displayed is displayed on the display device 30. It is also good.

  Furthermore, the stereoscopic image may represent content for operating the in-vehicle device. For example, as such content, an upward / downward arrow for adjusting the temperature of the air conditioner, a plus / minus symbol or the like may be displayed as a stereoscopic image. As described later, when such a stereoscopic image is moved upward by the occupant, control is performed to raise the temperature of the air conditioning. A stereoscopic image may be used as a user interface for such control.

A position, an orientation, and a motion at which the stereoscopic image illustrated in FIG. 4 is displayed will be described.
The display control unit 23 reads the content from the storage device 11 and causes the display device 30 to display the content. For example, the display control unit 23 causes the display device 30 to display stereoscopic images A to G of a plurality of contents.

  The display control unit 23 first determines the content to be displayed. For example, predetermined content is read from the storage device 11. Alternatively, the display control unit 23 searches the storage device 11 for contents related to the keyword, using the voice of the occupant recognized by the microphone 50 and the voice recognition unit 22 as a keyword.

  For example, the display control unit 23 may use, as predetermined content, a navigation system, a radio, a television, an audio device, an air conditioner, vehicle information such as speed and remaining amount of fuel, and contents related to facilities around the vehicle from the storage device 11 Read

FIG. 5 is a perspective view of a stereoscopic image of content displayed by the display device.
As shown to Fig.5 (a), the display control part 23 displays the content read from the memory | storage device 11 as each three-dimensional image AG. For example, on each surface of the three-dimensional image A, content related to the navigation system, for example, a current position or a destination on a certain surface, and a peripheral map on another surface are displayed. Also for the other stereoscopic images B to G, various contents are displayed on each surface.

  The display control unit 23 distributes and arranges a plurality of stereoscopic images A to G. Specifically, the display control unit 23 determines coordinates in the display area 31 so that the individual stereoscopic images A to G do not overlap, and displays the stereoscopic images A to G on the coordinates. These three-dimensional images A to G may always be displayed at a fixed position, or may be changed in position based on the operation of the occupant.

  For example, the display control unit 23 uniformly arranges the plurality of stereoscopic images A to G on one ring 32 with a predetermined interval, and causes the display area 31 to display the stereoscopic images.

  In addition, it is preferable that stereoscopic images A to G do not overlap on the line of sight L of the occupant. Such a line of sight L can be determined based on the front seat 2, the rear seat 3, the position of the average occupant's eyes, and the position of the display area 31.

The line of sight L of the occupant is virtually formed in the three-dimensional space, and the three-dimensional coordinates of each three-dimensional image are calculated so that two or more three-dimensional images are not arranged on the line of sight L. In the present embodiment, since there are four occupants at maximum, the four lines of sight L are virtually formed, and three-dimensional coordinates of each three-dimensional image so that two or more three-dimensional images are not arranged in each line of sight L Calculate
As a result, for the occupant, the stereoscopic images do not overlap, and the visibility of the plurality of stereoscopic images is improved.

  The three-dimensional images A to G displayed in the display area 31 may be rotated. For example, the display control unit 23 rotates the three-dimensional images A to G around the Z axis. Thus, the occupant can visually recognize the side surfaces of the three-dimensional images A to G in the seated state. Furthermore, the stereoscopic images A to G may move along the circumference of the ring 32. Since each of the three-dimensional images A to G approaches the occupant side with the passage of time, the visibility of the three-dimensional images is improved. Of course, the modes of rotation and movement of the stereoscopic image are not limited to those described above.

  Furthermore, the display control unit 23 causes the display device 30 to display the stereoscopic image selected by the operation of the occupant among the plurality of stereoscopic images, following the operation of the occupant.

  The display control unit 23 determines whether there is a stereoscopic image within a certain range from the coordinates of the hand of the occupant obtained by the detection unit 21. If it is determined that there is a stereoscopic image within a certain range from the coordinates of the hand, it is assumed that the stereoscopic image is selected by the occupant. In the example of FIG. 5A, it is determined that the stereoscopic image A has been selected by the occupant. Alternatively, it may be determined that a stereoscopic image is selected when a point motion is detected within a certain range from the stereoscopic image.

  In addition, when a specific operation (for example, an operation in which the hand is separated from the stereoscopic image A at a predetermined speed or higher) is detected in the state where the stereoscopic image is selected, it is determined that the selection of the stereoscopic image is cancelled.

  Displaying a stereoscopic image by following the operation of the occupant means changing the coordinate position, size, and direction of the stereoscopic image corresponding to the flick operation, slide operation, point operation, and pinch operation described above, or changing to a stereoscopic image. To change the content to be displayed.

  For example, as shown in FIG. 5 (a), when a pinch out operation is detected from a state in which the hand pinches the stereoscopic image A, the stereoscopic image A is enlarged and displayed as shown in FIG. 5 (b). The stereoscopic image A is enlarged in response to such an operation as enlarging the object of pinch-out operation. As a result, it is possible to realize the request of “want to see the stereoscopic image A in an enlarged manner” with an intuitive operation.

In addition, although not particularly illustrated, it is possible to display a stereoscopic image corresponding to each operation.
For example, when a pinch-in operation is detected in a state in which the hand pinches a stereoscopic image, the stereoscopic image is displayed in a reduced size. In this way, the stereoscopic image is reduced in response to an operation such as a pinch-in operation that reduces the object. As a result, it is possible to realize the requirement of “reduce the stereoscopic image and make it easy to view another stereoscopic image” by an intuitive operation.

  In addition, when a slide operation or a flick operation is detected from a state in which a hand selects a stereoscopic image, the stereoscopic image is moved according to the position of the hand. The three-dimensional image is moved in response to such an operation as moving the object of the slide operation. This makes it possible to realize the request "want to move a stereoscopic image" by an intuitive operation.

  Furthermore, when the hand detects a point motion on a stereoscopic image, the content related to the stereoscopic image may be searched and the content may be displayed as another stereoscopic image. For example, when a point operation is detected with respect to the side of the stereoscopic image A on which the “new arrival information” is displayed as shown in FIG. 4A, the content regarding the details of the new arrival information is displayed as another stereoscopic image. May be As a result, it is possible to realize the request “I want to know the details of the content displayed in the stereoscopic image” by an intuitive operation.

  When displaying a stereoscopic image in accordance with such an operation of the passenger's hand, predetermined processing may be executed according to the content.

FIG. 6 is a plan view showing a stereoscopic image for setting the in-vehicle apparatus.
In FIG. 6A, for example, the content related to the temperature setting of the air conditioner is displayed in the display area 31 as a stereoscopic image H. When the upward flick operation is detected, the display control unit 23 moves the stereoscopic image H upward and performs control to raise the temperature by, for example, 1 ° C. in the air conditioner. Similarly, when a downward flick operation is detected, the display control unit 23 moves the stereoscopic image H downward and performs control to lower the temperature by, for example, 1 ° C. in the air conditioner. After setting the temperature, the display control unit 23 returns the stereoscopic image H to the original position. In this way, the requirement of "raising or lowering the temperature of the air conditioning" can be realized by an intuitive operation.

  Further, in FIG. 6B, for example, content relating to the tuning setting of the radio is displayed in the display area 31 as a stereoscopic image I. When a flick operation in the left direction is detected, the display control unit 23 moves the stereoscopic image I in the left direction and changes it to a broadcasting station that uses a lower frequency than the currently selected broadcasting station. Similarly, when a flicking operation in the right direction is detected, the display control unit 23 moves the stereoscopic image I in the right direction and changes it to a broadcasting station that uses a higher frequency than the currently selected broadcasting station. Do. In this way, the request "to select a radio station" can be realized by an intuitive operation.

  In addition, for stereoscopic image, air volume of air conditioner, switching of operation mode of air conditioner (heating, cooling, air flow etc), volume and tuning of TV, volume, playing, stopping and fast forwarding of audio equipment The user interface may be configured to change the air volume or the like when a specific operation is detected for the stereoscopic image.

  Furthermore, the display control unit 23 may display a stereoscopic image in the direction in which the passenger's voice is emitted.

  FIG. 7 is a plan view showing a usage form of the on-vehicle user interface device by a plurality of occupants. As described above, the voice recognition unit 22 detects the position of the voice source (the position of the occupant). In the example of the same figure, it is assumed that the occupants seated in the front seat 2A and the front seat 2B respectively generate "weather" and "OO land". In this case, the voice recognition unit 22 detects that the front seat 2A and the front seat 2B are sources of voice.

  The display control unit 23 searches for a stereoscopic image representing content related to the sound emitted by the occupant from among the plurality of stereoscopic images. The display control unit 23 searches the storage device 11 for the stereoscopic image C and the stereoscopic image D corresponding to “OO land” and “weather”.

  Next, the display control unit 23 directs the stereoscopic image C and the stereoscopic image D toward the positions of their sources. Specifically, the main direction M of the stereoscopic image is defined in advance. For example, in the case of a cubic stereo image, the normal direction of one side is taken as the main direction, and in the case of a spherical stereo image, any direction orthogonal to the Z axis is taken as the main direction.

  Then, the display control unit 23 displays the stereoscopic image C and the stereoscopic image D such that the main direction M is directed to the sound source. Furthermore, the display control unit 23 may move and enlarge the three-dimensional image C and the three-dimensional image D toward the occupant.

  As described above, among the plurality of stereoscopic images, only the stereoscopic image C and the stereoscopic image D representing the content related to the sound emitted by the occupant can be displayed so as to be easily visible to the occupant.

  Furthermore, the display control unit 23 may copy and not only move and rotate the stereoscopic image based on the operation of the occupant.

  For example, it is assumed that the occupants of the rear seat 3A and the rear seat 3B select the stereoscopic image A and the stereoscopic image B, respectively, and then perform a slide operation in which the hand is pulled. When the slide control is detected, the display control unit 23 copies the selected stereoscopic image A and stereoscopic image B to generate a stereoscopic image A 'and a stereoscopic image B'. Then, the display control unit 23 moves the three-dimensional image A ′ and the three-dimensional image B ′ in accordance with the slide operation. That is, when the occupant touches the stereoscopic image A and pulls it forward, the stereoscopic image A 'is displayed so as to move in accordance with the hand of the occupant.

  As described above, since one stereoscopic image A is copied as a stereoscopic image A 'at the hand of the occupant, the stereoscopic image A' can be easily viewed by the occupant. Further, since the stereoscopic image A remains at the original position, other occupants can copy and view the stereoscopic image A at hand. That is, the three-dimensional image can be viewed at hand without exchanging one three-dimensional image among a plurality of occupants.

  As described above, the on-vehicle user interface device 10 can detect the motion of the occupant's hand, and can display the content as a stereoscopic image on the display device 30 so as to follow the motion. As a result, an intuitive user interface such as an occupant directly touching a stereoscopic image, moving it to an easy-to-see position, or enlarging it for easy viewing is realized.

  Further, the on-vehicle user interface device 10 can display a stereoscopic image toward the sound source of the passenger. As a result, the stereoscopic image can be displayed more easily to the occupant.

  Further, the in-vehicle user interface device 10 can copy and display a stereoscopic image according to the operation of the hand. Thereby, the three-dimensional image can be viewed at hand without exchanging one three-dimensional image among a plurality of crew members.

  Further, the on-vehicle user interface device 10 can search for content related to the voice emitted by the occupant and display the content as a stereoscopic image. This makes it possible to display desired content quickly and easily.

  Although the embodiment of the present invention has been described, of course, the present invention is not limited to the above-described embodiment, and additions, omissions, replacements, and additions of configurations can be made without departing from the spirit of the present invention. Other modifications are possible.
