Information processing apparatus and warning presentation method

A method, comprising:

• performing information processing on a basis of data received from a device that detects a user position, wherein the user position is determined based on a captured image;
• generating an image to be displayed as a result of the information processing, where a user wears a head mounted display and the image displayed obstructs the user's vision;
• determining that the user needs to be warned when the user position indicates that the user moves out of a play area set in an object space in reference to a detection field of the device, and to cause the image generating section to superpose a warning image on the image to be displayed;
• and
• transmitting data of the image generated by the image generating section to the head mounted display, where the transmitting includes outputting, to the head mounted display, a confirmation screen prompting the user to confirm that there is an obstacle, prior to outputting the data of the image, wherein the determining includes determining that the user needs to be warned when the user position does not match a predetermined range and play area and the determining further includes changing at least one of the predetermined range and play area based on the user position.

A non-transitory, computer readable storage medium containing a computer program, which when executed by a computer system, causes the computer system to carry out actions, comprising:

• performing information processing on a basis of data received from a device that detects a user position, wherein the user position is determined based on a captured image;
• generating an image to be displayed as a result of the information processing, where a user wears a head mounted display and the image displayed obstructs the user's vision;
• determining that the user needs to be warned when the user position indicates that the user moves out of a play area set in an object space in reference to a detection field of the device, and to cause the image generating section to superpose a warning image on the image to be displayed;
• and
• transmitting data of the image generated by the image generating section to the head mounted display, where the transmitting includes outputting, to the head mounted display, a confirmation screen prompting the user to confirm that there is an obstacle, prior to outputting the data of the image, wherein the determining includes determining that the user needs to be warned when the user position does not match a predetermined range and play area, and the determining further includes changing at least one of the predetermined range and play area based on the user position.
