Information processing device, information processing system, and information processing method

An information processing device system comprising:

• a user terminal and a server, wherein
• the user terminal includes:
• a posture estimation unit configured to estimate a user posture by inputting sensor detection values of motion sensors attached to a plurality of parts of a body of a user;
• a sensor detection value selection unit configured to selectively acquire a sensor detection value of a part having a motion faster than a prescribed threshold;
• and
• a communication unit configured to transmit the user posture estimated by the posture estimation unit and the sensor detection value selected by the sensor detection value selection unit to the server,
• the server
• generates a user posture-reflected three-dimensional avatar image by using the user posture and the sensor detection value received from the user terminal, and transmits the generated user posture-reflected three-dimensional avatar image to the user terminal, and
• the user terminal
• outputs the user posture-reflected three-dimensional avatar image received from the server to a display unit.

An information processing method executed in an information processing device, the information processing method executing:

• by a posture estimation unit, a posture estimation step of estimating a user posture by inputting sensor detection values of motion sensors attached to a plurality of parts of a user's body;
• by a sensor detection value selection unit, a sensor detection value selection step of selectively acquiring a sensor detection value of a part having a motion faster than a prescribed threshold;
• a step of outputting the user posture estimated by the posture estimation unit and the sensor detection value selected by the sensor detection value selection unit to an external device or a posture-reflected three-dimensional avatar image generation unit in the information processing device;
• and
• a step of outputting, to a display unit, a user posture-reflected three-dimensional avatar image generated by the posture-reflected three-dimensional avatar image generation unit using the user posture and the sensor detection value.
