Method and system for recognizing handprints and gestures

摘要

The present invention relates to a computer-implemented method, a computer program product, and a computer system (100) for recognizing a handprint. The system includes an interface component (110) configured to receive measurement data (11) from a motion sensor unit (10). The motion sensor unit (10) is physically coupled to the movable part (1) of the user's body, and the measurement data (11) includes sensor data of the sensors of the motion sensor unit (10). The sensor data corresponds to the second derivative with respect to the time of the trajectory (20) of the motion sensor unit (10). The system further includes a data storage component (130) that stores a technical profile associated with each character. The technical profile includes at least a plurality of predefined acceleration profiles. Each acceleration profile includes acceleration data that characterizes the movement associated with one particular part of a possible trajectory of the motion sensor unit (10), the context of at least one preceding or subsequent part of that possible trajectory. In The decoding component (120) of the system compares the received sensor data (11) with a plurality of predefined acceleration profiles to identify a sequence of parts of the trajectory (20). If the identified sequence consisting of parts of the trajectory (20) is associated with a predefined context-dependent sequence consisting of parts of a specific possible trajectory representing a particular character The decoding component identifies a specific character corresponding to the received sensor data (11). The representation of the identified character is supplied to the output device (200).
