Abstract
A sign language recognition method includes a depth-sensing camera capturing an image of a gesture of a signer and gathering data about distances between a number of points on the signer and the depth-sensing camera, building a three dimension (3D) model of the gesture, comparing the 3D model of the gesture with a number of 3D models of different gestures to find out the representations of the 3D model of the gesture, and displaying or vocalizing the representations of the 3D model of the gesture.
