INFORMATION PROCESSING DEVICE, GESTURE DETECTION METHOD, AND GESTURE DETECTION PROGRAM

It is possible to operate a device while reducing erroneous recognition of a device even when a line of sight does not face the device in an accurate direction. An information processing device that detects a motion of a user includes a detecting unit that detects the motion of the user and a face direction of the user from an image photographed by an imaging unit, a detected motion determining unit that determines whether or not the motion detected by the detecting unit is an operation on the information processing device based on the face direction of the user and position information of the information processing device stored in a storage unit in advance, and a display content control unit that causes a display unit to reflect the motion when the detected motion determining unit determines that the motion detected by the detecting unit is the operation on the information processing device.
