An information processing apparatus () includes a conversion unit () and a computation unit (). The conversion unit () detects a plurality of markers from a camera image (). The conversion unit () converts the detected markers into corresponding sub-identifier information. The computation unit () computes an identifier using a plurality of sub-identifiers converted by the conversion unit ().

Information processing apparatus, control method, and program

An information processing system () includes a marker (). The marker () is any part of the body of a user of the information processing system (), or is any object attached to the user of the information processing system (). An information processing apparatus () includes an operation region extraction unit () and a recognition unit (). The operation region extraction unit () extracts an operation region from a captured image on the basis of a position of the marker (). The recognition unit () calculates a position or motion of an operation body in the operation region on a captured image. The recognition unit () recognizes an input operation on the basis of the calculated position or motion of the operation body.

Information processing system, information processing apparatus, control method, and program

A marker () is any part of a user's body or is any mark attached to the user. A sensor () is attached to the user. An operation region calculation unit () calculates an operation region included in a captured image on the basis of a position of the marker () included in the captured image generated by a camera. A recognition unit () calculates a position or motion of an operation body captured in the operation region, and recognizes an input operation on the basis of the calculated position or motion of the operation body. Note that the recognition unit () calculates a position of the operation body captured in the operation region at a timing based on a result of detection by the sensor (). The recognition unit () calculates motion of the operation body captured in the operation region in a period including a timing based on a result of detection by the sensor ().
