Patent ID: 8416185

Claim:
An operational object controlling device that detects a motion of at least one part of the body of a user and selects a motion for an operational object according to the detected motion, the device comprising: a motion detecting unit for detecting the user's motions; a motion obtaining unit for obtaining the user's motion from the motions detected by the motion detecting unit at a plurality of predetermined intervals; a motion feature quantities extraction unit for extracting the user's motion feature quantities each of which is defined by one of frequency components obtained by applying a Fourier transformation on a temporal sequence of the user's motions obtained by the motion obtaining unit; a template storage unit for storing the templates which weight the frequency components of the user's motion feature quantities; an operational object motion storage unit for storing the temporal motion sequences of the operational object; a motion feature quantities transform unit for transforming the user's motion feature quantities, by use of a template that is obtained from the template storage unit according to environmental information of the user or the operational object; and an operational object motion obtaining unit for selecting one of the temporal motion sequences of the operational object in the operational object motion storage unit that has motion feature quantities close to the user's motion feature quantities transformed by the motion feature quantities transform unit.
