The invention relates to multi-sensor posture recognition. A system for using self-adpatation multi-sensor posture recognition to recognize postures is described. In some embodiments, a posture recognition system receives multiple sensor inputs from a plurality of sensor devices , and multiple confidence thresholds associated with the multiple sensor inputs. The confidence thresholds specify the minimal confidency value indicating that a certain posutre has already happened. Once a compensating event is detected, for example, for excessive motion of one of the multiple sensor devices, the posture recognition system can modify the multiple confidence thresholds based on the compensating event. Then, the posture recognition system generates and outputs multiple sensor confidence values based on that whether at least one subset in the multiple confidence values has been satisfied. The posture recognition system modifies the multiple confidence thresholds based on that the sensor input is inserted into the posture recognition system or pulled out from the posture recognition system.
