Abstract
A gesture recognition apparatus includes: 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; a normalization processing means for executing processing of normalization of first and second signals outputted from the first and second one-dimensional sensor means; 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 using x- and y-coordinate values based on the normalized first and second signals; a correlation coefficient calculation means for calculating a correlation coefficient with respect to the first and second signals using coordinate values forming the signal track; and a motion determination means for determining whether the detected movement is a motion in the first or second direction based on the value of the correlation coefficient.
