Abstract: A glove for use in collecting data for sign language recognition comprises: multiple azimuth sensors arranged on the glove at positions corresponding to the phalanges and metacarpal bones of the hand and used for sensing postures of the hand. The azimuth sensors are only arranged on the glove at positions corresponding to the phalanges of the hand other than the distal phalange in proximity to the fingertip of at least one finger among the middle finger, the index finger, the ring finger, and the little finger. The glove reduces the number of the azimuth sensors arranged on the glove at positions corresponding to the phalanges of the hand, thus reducing costs while not affecting detection performance.
