Information processing apparatus and method, and program

An information processing method, performed via at least one processor, the method comprising:

• initiating recognition of a hand shape image corresponding to a hand,
• calculating a hand shape matching degree between the recognized hand shape image and stored hand shape patterns,
• detecting a position and an angle of each part of a plurality of parts of the hand with respect to a display surface based on a position of the recognized hand image and a matching hand shape pattern of the stored hand shape patterns having a maximum calculated hand shape matching degree;
• presenting, when the maximum calculated hand shape matching degree is greater than a predetermined value, an operation input interface for each part of the hand including one or more operation buttons for each respective part of the hand at a plurality of positions along a respective angle on the display surface according to the detected position and the detected angle of the respective part of the hand;
• and
• presenting, when the maximum calculated hand shape matching degree is not greater than the predetermined value, an operation input interface for a selected part of the hand.

A non-transitory computer-readable storage medium having embodied thereon a program, which when executed by a computer causes the computer to execute a process, the process comprising:

• initiating recognition of a hand shape image corresponding to a hand,
• calculating a hand shape matching degree between the recognized hand shape image and the stored hand shape patterns,
• detecting a position and an angle of each part of a plurality of parts of the hand with respect to a display surface based on a position of the recognized hand image and a matching hand shape pattern of the stored hand shape patterns having a maximum calculated hand shape matching degree;
• presenting, when the maximum calculated hand shape matching degree is greater than a predetermined value, an operation input interface for each part of the hand including one or more operation buttons for each respective part of the hand at a plurality of positions along a respective angle on the display surface according to the detected position and the detected angle of the respective part of the hand;
• and
• presenting, when the maximum calculated hand shape matching degree is not greater than the predetermined value, an operation input interface for a selected part of the hand.
