GESTURE DETERMINATION APPARATUS AND METHOD
First Claim
1. A gesture determination apparatus comprising:
- a storage unit to store, for each gesture of a plurality of gestures, a feature of a locus necessary for determining the gesture and identification information of the gesture;
a gesture determination unit configured to determine, every time a point coordinate is input in time sequence from a input unit, whether an input locus, whish is formed from point coordinates which are input before the point coordinate is input and the point coordinate input from the input unit, satisfies the feature of the locus of one of the gestures stored in the storage unit, to output the identification information of the one of the gestures when the input locus satisfies the feature of the locus of the one of the gestures;
a standstill determination unit configured to determine, every time the point coordinate is input, whether a set of a plurality of point coordinates including point coordinates which are input during predetermined time before the point coordinate is input and the point coordinate input from the input unit are in a standstill state within a predetermined distance; and
a gesture repeat determination unit configured to determine a repeat of the one of the gestures when the standstill state is determined after the one of the gestures is determined, to output the identification information of the one of the gestures.

Abstract
A gesture determination apparatus, determines, every time a point coordinate is input in time sequence from an input unit, whether an input locus, which is formed from point coordinates input before the point coordinate is input and the point coordinate input from the input unit, satisfies a feature of a locus of a gesture stored in a storage unit, to output an identification information of the gesture when the input locus satisfies the feature of the locus of the gesture, determines, every time the point coordinate is input, whether point coordinates input during predetermined time before the point coordinate is input and the point coordinate input from the input unit are in a standstill state within a predetermined distance, and determines a repeat of the gesture when the standstill state is determined after the one of the gestures is determined, to output the identification information of the gesture.

11. A program stored in a computer readable storage medium which when executed by a computer results in performance of steps comprising:
-
storing, for each gesture of a plurality of gestures, a feature of a locus necessary for determining the gesture and an identification information of the gesture in a storage unit; inputting a point coordinate in time sequence; determining, every time a point coordinate is input in time sequence from an input unit, whether an input locus, which is formed from point coordinates which are input before the point coordinate is input and the input point coordinate input from the input unit, satisfies the feature of the locus of one of the gestures stored in the storage unit, to output the identification information of the one of the gestures when the input locus satisfies the feature of the locus of the one of the gestures; determining, every time the point coordinate is input, whether a set of a plurality of point coordinates including point coordinates which are input during predetermined time before the point coordinate is input and the input point coordinate input from the input unit are in a standstill state within a predetermined distance; and determining a repeat of the one of the gestures when the standstill state is determined after the one of the gestures is determined, to output the identification information of the one of the gestures.
