Patent ID: 8224619

Claim:
A gesture recognition apparatus comprising: first and second one-dimensional sensor means for detecting movement corresponding to a motion of an object in a one-dimensional direction along one detection axis and outputting a signal corresponding to the detected movement, in which detection axes are arranged along different directions with respect to a first direction and a second direction which are directions of linear motions of the object defined as a recognition target; a normalization processing means for executing processing of normalization by converting amplitude values of respective first and second signals outputted from the first and second one-dimensional sensor means into values represented by ratios with respect to peak values; a phase plane mapping processing means for forming a signal track corresponding to the first and second signals in time series by plotting coordinates on a phase plane by using x-coordinate values based on values of the normalized first signals and y-coordinate values based on values of the normalized second signals at respective same timings; a correlation coefficient calculation means for calculating a correlation coefficient with respect to the first and second signals by using coordinate values forming the signal track; and a motion determination means for determining whether the detected movement is a motion in the first direction or a motion in the second direction at least based on whether a value of the correlation coefficient is positive or negative.
