Abstract
There is provided a recognition system capable of correctly recognizing nodding action of a user and controlling interaction reflecting the user's intention. The instruction recognition system includes a gesture recognition section for recognizing the user's nodding action on the basis of a photographed image of the user's head; a line-of-sight detection section for detecting the line of the user's sight; a display section for indicating image data; and a controller which determines the candidate for selection, toward which the line of sight is directed, to be selected and which performs predetermined processing when the nodding action recognition section detects nodding action and when the line of sight detected by the line-of-sight detection section is oriented toward any one of the candidates for selection during the nodding action, while the system awaits the user's instruction and one or a plurality of candidates for selection are displayed on the display section.
