摘要
The present invention discloses a method and system for obtaining and tracking motions and gestures of a body part (e.g. a hand) of a user, by using antennas worn on the body (e.g. on a wrist band). The antennas may be near-field antennas which transmit and receive short-range electromagnetic fields. The electromagnetic fields may be modified by interaction with the body part, depending on the exact position of the body part. The modified electromagnetic field may be received by the antennas. The received signal may be processed, to provide additional spatial information (e.g. beamforming). The processed signal may be interpreted by pattern recognition (e.g. neural network, database table). The pattern recognition may be trained using labeled pair data (e.g. known hand positions and corresponding processed signals).
