Document Type and Number:
WIPO Patent Application WO/2020/029146
Kind Code:
A1
Abstract:
The present application provides a method for obtaining a movement track of a user and a terminal, relating to the technical field of the communications, facilitating to improve the accuracy that the terminal obtains the movement track of the user and improving the accuracy of obtaining the movement track of the user. The method comprises: obtaining gravity data of the terminal; determining that the terminal is in a first posture in a first time period; determining the movement direction of the user in the first time period according to azimuth
angle data on the basis of the first posture; determining that the terminal is in a non-stable state in a second time period adjacent to the first time period; determining the movement direction of the user in the second time period according to the movement direction of the user in the first time period; determining that the terminal is in a stable state in a third time period adjacent to the second time period; determining, by the terminal, the movement direction of the user in the third time period according to the movement direction of the user in the second time period and the azimuth angle data; and determining, by the terminal, the movement track of the user according to the movement direction of the user in respective time periods.
