Abstract

A virtual space display system for a self-driving moving body displays a virtual space different from a real environment such that a passenger on the moving body can enjoy the virtual space without feeling strange for a motion. The system includes a display device, a surrounding situation detector, and a virtual space display unit. The surrounding situation detector obtains information specifying features that influence a path along which the moving body is to move, and specifies such an important feature among features located in the surrounding of the moving body that presence/absence of the important feature has an influence on the path of the moving body. The virtual space display unit converts the important feature into an object that is fit for the influence on the path of the moving body based on a predetermined rule, and causes the display device to display the virtual space including the converted object.

Claims

1. A virtual space display system that provides a passenger on a self-driving moving body with display of a virtual space that is different from a real environment surrounding the moving body, the virtual space display system comprising:

a display device configured to provide the passenger with the display of the virtual space;

a surrounding situation detector configured to obtain information specifying features that influence a path along which the moving body is to move, and to specify such an important feature among features located in the surrounding of the moving body that presence or absence of the important feature has an influence on the path of the moving body; and

a virtual space display unit configured to convert the important feature into an object that is fit for the influence on the path of the moving body, based on a predetermined rule, and to cause the display device to display the virtual space including the converted object.

2. The virtual space display system according to claim 1,

wherein the display device is one of a wearable display device which the passenger wears and an immersive display device.

3. The virtual space display system according to claim 1,

wherein the surrounding situation detector further specifies a feature that has an influence on a moving speed of the moving body as the important feature.

4. The virtual space display system according to claim 3,

wherein the important feature is a feature having an appearance that changes in such a manner that influences a feeling or expectation of the passenger, and

wherein the virtual space display unit predicts or detects a change corresponding to the changed appearance of the important feature, and displays the virtual space including the object with the predicted or detected change reflected on an appearance or a position of the object.

5. The virtual space display system according to claim 3,

wherein the important feature is a feature having a position that changes in such a manner that influences a feeling or expectation of the passenger, and

wherein the virtual space display unit predicts or detects a change corresponding to the changed position of the important feature, and displays the virtual space including the object with the predicted or detected change reflected on an appearance or a position of the object.

6. The virtual space display system according to claim 1,

wherein the important feature is a feature having an appearance that changes in such a manner that influences a feeling or expectation of the passenger, and

wherein the virtual space display unit predicts or detects a change corresponding to the changed appearance of the important feature, and displays the virtual space including the object with the predicted or detected change reflected on an appearance or a position of the object.

7. The virtual space display system according to claim 1,

wherein the important feature is a feature having a position that changes in such a manner that influences a feeling or expectation of the passenger, and

wherein the virtual space display unit predicts or detects a change corresponding to the changed position of the important feature, and displays the virtual space including the object with the predicted or detected change reflected on an appearance or a position of the object.

8. The virtual space display system according to claim 1,

wherein the virtual space display unit converts the important feature into the object by referring to a predetermined correspondence relationship according to a type of the important feature.

9. The virtual space display system according to claim 1,

wherein the virtual space display unit converts, in addition to the important feature, at least part of other features that are located in the surrounding of the moving body into at least one second object according to a predetermined rule, and displays the virtual space including the second object.

10. The virtual space display system according to claim 1,

wherein the virtual space is a play space where the passenger plays.

11. A virtual space display method that provides a passenger on a self-driving moving body with display of a virtual space that is different from a real environment surrounding the moving body, the virtual space display method comprising computer-implemented steps of:

obtaining information that specifies features that influence a path along which the moving body is to move, and specifying such an important feature among features located in the surrounding of the moving body that presence or absence of the important feature has an influence on the path of the moving body; and

converting the important feature into an object that is fit for the influence on the path of the moving body, based on a predetermined rule, and of causing a display device configured to provide the passenger with the display of the virtual space, to display the virtual space including the converted object.

12. A computer readable recording medium in which a computer program is recorded, wherein the computer program is performed to provide a passenger on a self-driving moving body with display of a virtual space that is different from a real environment surrounding the moving body,

the computer program causing a computer to implement:

a function of obtaining information that specifies features influence a path along which the moving body is to move, and thereby specifying such an important feature among features located in the surrounding of the moving body that presence or absence of the important feature has an influence on the path of the moving body; and

a function of converting the important feature into an object that is fit for the influence on the path of the moving body, based on a predetermined rule, and of causing a display device configured to provide the passenger with the display of the virtual space, to display the virtual space including the converted object.
