Abstract：Users are biologically different when they click on a mobile terminal. This paper focuses on the use of gyroscope sensors to study the click operation of users. Firstly, by the use of the study on the behavior of touching screen, we propose the slope of gyroscope which can reflect the shaking acceleration of mobile phone as a new user behavior feature. Secondly, we use the algorithm of sliding window to expand the user's click operation from "finger touch screen" to the three processes of "finger click", "finger touch screen" and "finger lift". New features are extracted for these three processes. In the experimental stage, according to the feature that shaking is related to the clicking position, the screen is divided into regions. The experimental data are grouped according to the partition area, and the low shaking area is filtered through the identification of the hands. The accuracy rate reached 95%.
