Title:
METHOD AND APPARATUS FOR DETECTING WEAR STATE OF SMART WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/075914
Kind Code:
A1
Abstract:
A method and apparatus for detecting the wear state of a smart wearable device. A first effective average value of a first infrared reflection signal and a second effective average value of a second infrared reflection signal are obtained by using that the difference in reflection of different objects to infrared rays of different light intensities; and the difference between the first effective average value and the second effective average value is used to determine the wear state of the smart wearable device, thereby avoiding an erroneous determination caused by determining the wear state based on distances, and the erroneous determination caused by determination conditions such as a temperature difference and a capacitance difference which are greatly affected by the surrounding environment. The reflection signals of two light intensities are compared to improve the accuracy of determination.
