Information processing device and information processing method

An information processing method comprising:

• acquiring data regarding a camera image which is captured by a camera mounted to a head-mounted display and in which a surrounding space of a user appears;
• detecting an obstacle in the surrounding space on a basis of the camera image and setting, on a basis of a result of the detection, a play area in which the user is allowed to move;
• and
• executing warning processing for the user according to a relation between a position of the user during play of an application that uses the head-mounted display and a boundary of the play area,
• wherein the setting the play area identifies a positional relation between the boundary of the set play area and a newly detected obstacle and determines whether or not to correct the boundary of the play area according to a result of the identification.

A computer program for a computer, comprising:

• by a camera image acquisition section, acquiring data regarding a camera image which is captured by a camera mounted to a head-mounted display and in which a surrounding space of a user appears;
• by a play area setting section, detecting an obstacle in the surrounding space on a basis of the camera image and setting, on a basis of a result of the detection, a play area in which the user is allowed to move;
• and
• by a warning processing section, executing warning processing for the user according to a relation between a position of the user during play of an application that uses the head-mounted display and a boundary of the play area,
• wherein the setting the play area identifies a positional relation between the boundary of the set play area and a newly detected obstacle and determines whether or not to correct the boundary of the play area according to a result of the identification.
