APPARATUS AND METHOD FOR ADAPTIVELY ADJUSTING THRESHOLD VALUE OF MOTION SENSOR IN WEARABLE DEVICE

摘要

The present invention relates to an apparatus and a method for adaptively adjusting a threshold value of a motion sensor in a wearable device, capable of improving accuracy by identifying a motion of a user by utilizing a determined threshold value of the motion sensor, and evaluating and adaptively adjusting the threshold value of the motion sensor according to a utilization result. The apparatus for adaptively adjusting a threshold value of a motion sensor in a wearable device includes: a control unit for controlling the power of a driving unit according to a value and a threshold value of the motion sensor of the wearable device, and adaptively adjusting the threshold value; and the driving unit for performing driving of the wearable device, wherein the control unit includes: a motion processing unit for acquiring acceleration and angular velocity values from the motion sensor, removing noise, performing normalization, and collecting each of the values to calculate a motion; a threshold value analysis unit for determining whether to drive according to the threshold value; a driving control unit for operating the driving unit to receive a driving result, and shutting off the power of the driving unit; and an adaptive threshold value adjustment unit for adaptively adjusting the threshold value, which is used to determine whether to drive or not, by using the driving result.;COPYRIGHT KIPO 2020
