WEARABLE SYSTEM AND METHOD FOR BALANCING RECOGNITION ACCURACY AND POWER CONSUMPTION

摘要

A method for balancing recognition accuracy and power consumption is provided. The method includes activating a plurality of sensors onboard a device for a first time period and calculating sensor readings by using a calculation function. The method also includes determining a plurality of sensor subsets of the plurality of sensors and calculating corresponding errors for the plurality of sensor subsets for the first time period. Further, the method includes calculating respective power consumption of running the sensor subsets of the plurality of sensors from the plurality of sensor subsets that produce the error below the user-defined error threshold and selecting a sensor subset with minimum power consumption from the sensor subsets as an optimal sensor subset. In addition, the method includes deactivating the plurality of sensors not in the optimal sensor subset and calculating and displaying sensor readings with the optimal sensor subset for a second time period.

1. A method for balancing recognition accuracy and power consumption, comprising:
activating a plurality of sensors onboard a device for a first time period; based on sensor data sent from the activated sensors, calculating sensor readings by using a calculation function; determining a plurality of sensor subsets of the plurality of sensors; calculating corresponding errors for the plurality of sensor subsets for the first time period; comparing the obtained errors to a user-defined error threshold; from the plurality of sensor subsets that produce the error below the user-defined error threshold, calculating respective power consumption of running the sensor subsets of the plurality of sensors; selecting a sensor subset with minimum power consumption from the sensor subsets as an optimal sensor subset; deactivating the plurality of sensors not in the optimal sensor subset; and calculating sensor readings with the optimal sensor subset for a second time period substantially longer than the first time period.
