Abstract

An information processing apparatus controls an HMD in accordance with touch operation on a touch operation surface. In calibration of the touch operation, the information processing apparatus controls the HMD such that a first display position, which is a position in an image displayed by the HMD, is identifiable, causes a user to perform touch on the touch operation surface while being conscious of the first display position, acquires information on a first touch position that is a position at which the touch is performed, controls the HMD such that a second display position that has a predetermined positional relation with the first display position is identifiable, causes the user to perform touch on the touch operation surface while being conscious of the second display position, and acquires information on a second touch position that is a position at which the touch is performed.

Claims16

Dependent claims

An information processing apparatus comprising:

one or more processors and/or circuitry configured to control a head-mounted display apparatus in accordance with touch operation on a touch operation surface,
wherein, in calibration of the touch operation, the one or more processors and/or circuitry:
(1) controls the head-mounted display apparatus such that a first display position, which is a position in an image displayed by the head-mounted display apparatus, is identifiable;
(2) causes a user to perform touch on the touch operation surface while being conscious of the first display position, and acquires information on a first touch position that is a position at which the touch is performed;
(3) controls the head-mounted display apparatus such that a second display position that has a predetermined positional relation with the first display position is identifiable;
and
(4) causes the user to perform touch on the touch operation surface while being conscious of the second display position, and acquire information on a second touch position that is a position at which the touch is performed, and
wherein, in a case where touch on the touch operation surface is performed after the calibration, the one or more processors and/or circuitry:
(1) determines a direction from the first touch position toward a third touch position that is a position at which the touch is performed;
(2) determines a distance from the first touch position to the third touch position;
(3) adjusts the determined distance by a magnification factor based on a ratio of a distance from the first display position to the second display position with respect to a distance from the first touch position to the second touch position;
and
(4) determines that a position that is away from the first display position by the adjusted distance in a direction based on the determined direction is designated.

10 more elements

A non-transitory computer-readable medium that stores a program, wherein the program causes a computer to execute a control method of an information processing apparatus configured to control a head-mounted display apparatus in accordance with touch operation on a touch operation surface, the control method comprising:

a step of executing calibration of the touch operation, wherein the step of executing the calibration includes:
(1) a step of controlling the head-mounted display apparatus such that a first display position, which is a position in an image displayed by the head-mounted display apparatus, is identifiable;
(2) a step of causing a user to perform touch on the touch operation surface while being conscious of the first display position, and acquires information on a first touch position that is a position at which the touch is performed;
(3) a step of controlling the head-mounted display apparatus such that a second display position that has a predetermined positional relation with the first display position is identifiable;
and
(4) a step of causing the user to perform touch on the touch operation surface while being conscious of the second display position, and acquire information on a second touch position that is a position at which the touch is performed, and
wherein, in a case where touch on the touch operation surface is performed after the calibration:
(1) a direction from the first touch position toward a third touch position that is a position at which the touch is performed is determined,
(2) a distance from the first touch position to the third touch position is determined,
(3) the determined distance is adjusted by a magnification factor based on a ratio of a distance from the first display position to the second display position with respect to a distance from the first touch position to the second touch position, and
(4) it is determined that a position that is away from the first display position by the adjusted distance in a direction based on the determined direction is designated.
