Claims

A program that is run on a computer to provide a virtual experience to the user via an image display device associated with the user.
The steps to define a virtual space to provide the virtual experience,
The step of moving the virtual viewpoint arranged in the virtual space and
The step of controlling the line-of-sight direction of the virtual viewpoint and
A step of detecting the difference between the moving direction of the virtual viewpoint and the line-of-sight direction of the virtual viewpoint,
Based on the difference, a step of determining the visibility of one or more objects included in the range of the field of view from the virtual viewpoint determined according to the line-of-sight direction of the virtual viewpoint, and
A step of generating a field of view image, which is an image corresponding to the range of the field of view,
A program for executing a step of outputting the field of view image to the image display device.

In the step of determining, when the absolute value of the difference is larger than the first value, the visibility of the object of 1 or more is lowered as compared with the case where the absolute value of the difference is not more than the first value. The program described in.

In the step of determining, claim 1 or 2 increases the degree of decrease in visibility of the one or more objects as the absolute value of the difference increases until the absolute value of the difference becomes the second value. The program described in.

In the step of determining, the total number of objects of 1 or more is reduced when the absolute value of the difference is larger than the first value than when the absolute value of the difference is less than or equal to the first value. The program according to any one of 1 to 3.

In the step of determining, when the absolute value of the difference is larger than the first value than when the absolute value of the difference is not less than or equal to the first value, the color of the object of 1 or more and the color of the object of 1 or more and the above 1 or more. The program according to any one of claims 1 to 4, which reduces the difference from the color around a predetermined object.

The program is on the computer
Along the guide object that guides the moving object to move in the depth direction, the step of moving the moving object in the depth direction is further executed.
The virtual viewpoint is located behind the moving object or on the moving object.
In the step of moving the virtual viewpoint, the virtual viewpoint is moved in the depth direction in conjunction with the movement of the moving object in the depth direction.
The program according to any one of claims 1 to 5, wherein the one or more objects are included in the range of the field of view from the virtual viewpoint and are arranged outside the range defined by the guide object. ..

A shielding object capable of shielding one or more predetermined objects from the virtual viewpoint is arranged at the boundary portion of the guide object.
According to claim 6, in the step of determining, the transparency of the shielding object is reduced when the absolute value of the difference is larger than the case where the absolute value of the difference is equal to or less than the first value. Program.

Based on the difference, the visibility of one or more objects included in the range of the field of view from the virtual viewpoint determined according to the line-of-sight direction of the virtual viewpoint is determined.
A field of view image, which is an image corresponding to the range of the field of view, is generated.
A computer that outputs the field of view image to the image display device.

A method performed on a computer to provide a virtual experience to a user through an image display device associated with the user.
The steps to define a virtual space to provide the virtual experience,
The step of moving the virtual viewpoint arranged in the virtual space and
The step of controlling the line-of-sight direction of the virtual viewpoint and
A step of detecting the difference between the moving direction of the virtual viewpoint and the line-of-sight direction of the virtual viewpoint,
Based on the difference, a step of determining the visibility of one or more objects included in the range of the field of view from the virtual viewpoint determined according to the line-of-sight direction of the virtual viewpoint, and
A step of generating a field of view image, which is an image corresponding to the range of the field of view,
A method comprising a step of outputting the field of view image to the image display device.
