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

An information processing apparatus comprising a processor and memory storing instructions,

• wherein the processor is configured to:
• extract an operation region from a captured image generated by a camera, the extraction being performed on the basis of a position of a marker;
• calculate a position or motion of an operation body in the operation region, and recognize an input operation on the basis of the calculated position or motion;
• and
• display an operation region image indicating the operation region on a display device,
• wherein the marker is attached to a user or is a part of the body of the user,
• wherein the operation region can be divided into more than one region, and
• wherein the input operation further comprises using at least one finger or an object held by the user in the operation region.

A control method executed by a computer, comprising:

• extracting an operation region from a captured image generated by a camera, the extraction being performed on the basis of a position of a marker;
• and
• calculating a position or motion of an operation body in the operation region, and recognizing an input operation on the basis of the calculated position or motion,
• wherein the marker that is an image displayed on a display of a device attached to a user,
• wherein the operation region can be divided into more than one region, and
• wherein the input operation further comprises using at least one finger or an object held by the user in the operation region.
