Abstract:
A hand gesture recognizing device for recognizing hand gestures performed by a user, comprising:a photographing device having at least two cameras and operable to take stereoscopic pictures of the user;an image storage device operable to store stereoscopic image data of the user outputted from the photographing device at an arbitrary sampling interval;a feature image extracting device operable to remove the stereoscopic image data in order from the image storage device, extract a feature image showing body features of the user from each of the stereoscopic image data, and disassemble and output the feature image in a plurality of channels;a spatial position calculating device operable to detect three-dimensional spatial positions of body parts of the user based on a parallax of the feature image outputted from said feature image extracting device;a region dividing device operable to divide a space surrounding the user into a plurality of regions related to the body of the user based on the parallax of the feature image outputted from said feature image extracting device;a hand gesture detecting device operable to detect how three-dimensional spatial positions corresponding to hands of the user, in the three-dimensional spatial positions of the body parts calculated by said spatial position calculating device, move with respect to the regions divided by said region dividing device;a hand gesture word determining device operable to determine a corresponding hand gesture word based on the movement of the hands detected by said hand gesture detecting device; andan output device operable to output a result determined by said hand gesture word determining device in a form which can be recognized by an operator.
