Title:
METHOD FOR DETERMINING STEP LENGTH OF USER BY USING MOTION SENSOR AND GPS MODULE OF ELECTRONIC DEVICE, AND ELECTRONIC DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2022/191444
Kind Code:
A1
Abstract:
Disclosed is an electronic device comprising: a motion sensor for outputting motion data; a GPS module for receiving a GPS signal; memory for storing a plurality of step length correction coefficients together with corresponding first parameter values and second parameter values; and a processor electrically connected to the motion sensor, the GPS module, and the memory, wherein the processor: recognizes a step event of a user on the basis of the motion data; determines a first parameter value and a second parameter value on the basis of the motion data, if the strength of the GPS signal is less than a reference value; determines a step length correction coefficient corresponding to the determined first parameter value and the determined second parameter value, among the plurality of step length correction coefficients stored in the memory; and determines the step length of the user on the basis of the determined step length correction coefficient and the motion data. Other various embodiments identified through the present document are possible.
