DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a specific embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram of an input / output method according to an embodiment of the present invention.

First, as a viewing angle control display device, for example, a lenticular lens as shown in the specifications of Japanese Patent Application Nos. 3-172606 and 3-226675 is used. A device that displays an image corresponding to the direction is used. As a result, it is possible to display a plurality of different screens depending on the viewing direction. FIG. 1B shows an example of the angle-dependent multiplex input / output device 10 using the viewing angle control display device, and shows a view from above. Images corresponding to each viewing direction are sequentially arranged behind each lenticular lens 11. Therefore, each pixel 12
Are divided into, for example, light emitting / receiving elements according to the viewing direction from 1 to 6. Note that the correspondence between the display screen and the lens slightly shifts away from the center of the screen.

The light emitted by the elements 1 to 6 in each pixel 12 propagates in the respective viewing directions via the lenticular lens 11, as shown in FIG. This light reaches persons P1 to P6 standing at different angles with respect to the angle-dependent multiplexing input / output device 10, and for example, the light emitted from the second element in the pixel 12 is P2.
Only people can see.

When this optical path is moved backward, only the light coming from the viewing angle at which the screen is displayed will reach one of the elements that compose the screen. If this is detected by a light receiving element or the like, a person who looks at the screen can input an instruction by a light beam emitted from the place where the person is.

FIG. 2 shows an arrangement example of a light emitting element and a light receiving element constituting each pixel in the angle-dependent multiplex input / output device 10 used in this embodiment. For example, as shown in FIG. 2, the light emitting elements 20 corresponding to the viewing directions 1 to 6 are arranged in each pixel 12 forming the screen in the view angle control display device using the lenticular lens 11. The light emitting elements 20 are arranged at intervals between pixels to reduce the arrangement density, and the light receiving elements 21 are arranged in the gaps. By doing so, only the light emitted from the angle at which the screen can be seen can be received by the light receiving element 21 according to the direction.

In this embodiment, assuming six viewing directions,
Since six kinds of screens are simultaneously displayed, each pixel has six light emitting portions, but it goes without saying that the present invention is not limited to six.

FIG. 3 is an explanatory view of the incident angle control input.
In order to prevent light from leaking from the adjacent lenses, a light shielding curtain 30 is installed between the lenses, for example. As a result, it is possible to prevent incidence from the adjacent lens and improve input accuracy.

By the above method, as shown in FIG.
Different screens are displayed for multiple people at different angles to the screen, and those people use position pointing devices that use light rays on the screen, such as a laser pointer or a penlight with a narrowed beam. You can enter the instructions separately. When the resolution for distinguishing the pointing input position and the display resolution are relatively low or the lenticular lens configuration density of the display device is relatively high, the incident light is incident even in the direction perpendicular to the viewing angle control direction. The directions can be distinguished.

When distinguishing not only the angle in the horizontal direction but also the angle in the vertical direction, for example, as shown in FIG.
Divide the screen into small pieces and put the lenticular lenses next to each other 90
The lenticular lens 11H and the vertical lenticular lens 11H may be rotated once to be combined as a vertical lenticular lens 11V, and these may be arranged in a checkered pattern. In addition, in order to accurately input / output all the vertical and horizontal angles, a small convex lens may be arranged for each pixel instead of the lenticular lens.

The specific method of use will be described below. (1) Exhibition explanation device Fig. 6 shows an example of an exhibition explanation device using the present invention. In an exhibition facility that interactively explains exhibits, if the actual exhibit is placed as shown in Fig. 6 and the angle-dependent multiplexing input / output device 10 is installed under it, only one screen is displayed. Thus, it is possible to realize a device for interactively giving different explanation contents to different visitors at the same time. In this case, a laser pointer or the like will be distributed to the visitors in advance.

(2) Three-dimensional display / instruction input device FIG. 7 shows an example of a three-dimensional display / instruction input device using the present invention. By the viewing angle control display, a pseudo three-dimensional display using horizontal motion parallax (the appearance of an object changes depending on the horizontal movement) is performed. At this time, the viewer can point the screen from each viewpoint with the screen pointing device that uses light rays. As a result, it becomes possible to display a three-dimensional object and input an instruction for it. This is useful when multiple people have to observe and direct a complex object or problem in real time. This can be used, for example, in a case where a person is instructing one's own part one after another while grasping the entire movement (sharing information on a global scale) such as a currency exchange transaction.

As an application of this, shooting (shooting)
If used on the screen of the game, a plurality of participants can move in the viewing angle control direction (eg, horizontal direction) with respect to the screen and attack while avoiding the enemy's shooting. If you move, a screen corresponding to the moving place is displayed, and you can shoot the target hidden in front. Since the incident direction and the position on the screen are known for this shooting, it is possible to determine the hit by calculating the three-dimensional position of the enemy and the ally.

(3) Interactive Program System for Simultaneously Displaying Multiple Languages FIG. 8 shows an example of application to a simultaneous display of multiple languages interactive program using the present invention. Participants are located at different angles in front of the screen for each language. The screen is basically the same, but the explanation is added in the language according to each viewing direction. Each participant can indicate his / her intention by pointing the screen using a penlight or the like.
Therefore, participants can share and discuss the same issues beyond language issues. In addition, the input from each participant can be tabulated for each language.

(4) Individual screen display device FIG. 9 shows an example of an individual screen display device using the present invention. Distribute a screen pointing device using rays to each participant.
At this time, a color (frequency) and a modulation method at the time of light emission are assigned to each individual so that the individual can be identified on the light receiving screen side. In this state, when each individual wants to receive information, he or she points to the screen with the screen pointing device from the position where he / she is, the individual is judged from the color of the ray, etc. Display in the direction. As a result, it is possible to individually send and receive information to a plurality of individuals using one large screen. Also, by using an indicator that can output various colors and modulations, different information can be displayed from each position and information can be retrieved interactively.

[0021]

As described above, according to the present invention,
With one display / input device, different viewers can display different screens and receive instruction inputs, and spatial multiplexing can be realized in interactive information exchange using the screens. Therefore, it can be applied to exhibition explanation devices and other devices to effectively use space and realize new services.
