Method of providing virtual space and system for executing the same

1. A method, comprising:

defining a virtual space;

receiving a first sound signal from a first user associated with a head-mounted device (HMD);

capturing an image in virtual space in response to receiving the first sound signal;

storing the captured image corresponding to at least a part of the virtual space in response to capturing the image;

receiving a second sound signal from a second user different from the first user;

capturing the image in the virtual space in accordance with the reception of the first sound signal and the second sound signal;

identifying a time difference between the reception of the second sound signal and the reception of the first sound signal; and

capturing the image in response to the time difference being equal to or less than a predetermined threshold.

2. The method according to claim 1 ,

wherein the virtual space comprises a first virtual camera and a second virtual camera different from the first virtual camera, and

wherein the method further comprises:

detecting a motion of the HMD;

moving the first virtual camera in accordance with the detected motion of the HMD;

defining a first visual field in the virtual space in accordance with the motion of the first virtual camera;

generating a first visual-field image corresponding to the first visual field;

outputting the first visual-field image to the HMD;

defining a second visual field in the virtual space in accordance with a position of the second virtual camera in the virtual space;

generating a second visual-field image corresponding to the second visual field; and

storing, in response to capturing the image, the second visual-field image as the captured image.

3. The method according to claim 1 ,

wherein the virtual space comprises a first avatar associated with the first user, and

wherein the method further comprises:

identifying a first position, which is a position of the first avatar in the virtual space;

setting, based on the first position, in image capturing range in the virtual space such that at least a part of the first avatar is included in the image capturing range; and

storing the captured image corresponding to the photographing range.

4. The method according to claim 3 , further comprising:

identifying a line-of-sight direction of the first avatar; and

setting the image capturing range in accordance with the line-of-sight direction and the position of the first avatar in the virtual space.

5. The method according to claim 3 ,

wherein the virtual space comprises a first virtual camera and a second virtual camera different from the first virtual camera, and

wherein the method further comprises:

detecting a motion of the HMD;

moving the first virtual camera in accordance with the detected motion of the HMD;

defining a first visual field in the virtual space in accordance with the motion of the first virtual camera;

generating a first visual-field image corresponding to the first visual field;

outputting the first visual-field image to the HMD;

determining a movement path of the second virtual camera in the virtual space in accordance with the position of the first avatar in the virtual space;

defining a second visual field in the virtual space in accordance with a position of the second virtual camera in the virtual space;

generating a second visual-field image corresponding to the second visual field; and

storing, in accordance with the capturing of the image, the second visual-field image as the captured image.

6. The method according to claim 1 , further comprising:

detecting a magnitude of the first sound signal; and

capturing the image in response to the magnitude of the first sound signal being equal to or greater than a first threshold.

7. The method according to claim 1 , further comprising:

extracting a character string from the first sound signal; and

capturing the image in response to the character string includes a first character string determined in advance.
