Abstract:
An instruction recognition system having a gesture recognition function for recognizing a user's gesture, the system comprising:a nodding action recognition section which detects the user's nodding action on the basis of a photographed image of a user's head; a line-of-sight detection section for detecting the line of a user's sight; a display section for indicating image data; a determination section which determines whether or not the nodding action recognition section has detected nodding action defined as one of a down then up and an up then down head movement performed in continuum within a specified period of time and the line of sight detected by the line-of-sight detection section during the nodding action is directed toward any of the candidates for selection, while the system awaits the user's instruction and one or a plurality of candidates for selection are displayed on the display section; an execution section which performs predetermined processing, on the assumption that the candidate toward which the line of the user's sight is directed will be selected, when the determination section determines that the nodding action recognition section has detected nodding action and that the line of sight detected by the line-of-sight detection section during the nodding action is directed toward any of the candidates for selection, while the system awaits the user's instruction and one or a plurality of candidates for selection are displayed on the display section.
