A behavior recognition apparatus includes: a hand movement observation unit (101) which outputs hand movement data indicating a hand movement made by a user; a velocity variation detection unit (102) which detects a time at which the hand movement matches a predetermined movement pattern; a feature selection unit (103) which selects the hand movement data outputted at the time detected by the velocity variation detection unit (102); a standard behavior pattern storage unit (104) which stores a movement pattern data sequence represented by a hand movement data sequence, in association with a user behavior; and a behavior recognition unit (105) which calculates a degree of similarity between the movement pattern data sequence stored in the standard behavior pattern storage unit (104) and the hand movement data selected by the feature selection unit (103), and recognizes, as the user behavior, a behavior represented by the movement pattern data sequence when the degree of similarity is the highest.
