Problems solved by technology

[0003] However, since the screen display mode of the terminal device is only changed through the direction of the acceleration of gravity, it can only adapt to an angular relationship between the user's line of sight and the direction of the acceleration of gravity, which has limitations and the recognition accuracy is not high
When the direction of the user's equipment is fixed and the direction of sight changes, the flipping cannot be realized or wrongly realized, which cannot bring a comfortable operating environment and user experience
[0004] At the same time, the terminal device uses the gravity sensor to realize the screen flip, which increases the power consumption of the device system, which increases the cost of the device and the user's use cost

Abstract

The invention relates to the sensing technology, and discloses a direction sensing implementing method and a terminal device. The method comprises the steps of recognizing the positions and directions of eyeballs of a user through a front-facing camera of the terminal device; drawing a connecting line of the eyeballs of the user; determining the viewing direction of the user according to the position relationship of the connecting line of the eyeballs of the user and a short side and a long side of the terminal device; adjusting the screen display direction of the terminal device to be the display direction in match with the determined viewing direction of the user. With the adoption of the method, the screen display direction can be accurately matched with the viewing direction of the user, thus a comfortable operation environment is created, and the experience of the user is increased; in addition, the front-facing camera is a functional part of the terminal device and can be used for easily detecting the positions and directions of the eyeballs of the user with the shooting function, thus the connecting line of the eyeballs of the user can be drawn, and complex calculation and conversion can be avoided; moreover, additional sensor is saved, so that the cost of the terminal device is decreased, and the additional power consumption is avoided.

Description

technical field [0001] The invention relates to sensing technology, in particular to a method for realizing direction sensing of terminal equipment. Background technique [0002] Most of the screen flipping functions of existing terminal devices (such as mobile phones) are realized through gravity sensors. The gravity sensor calculates the relationship between the generated voltage and the applied gravitational acceleration based on the piezoelectric effect, and converts the gravitational acceleration into a voltage output. The gravity sensor in the terminal device senses the direction of the acceleration of gravity of the device and converts it into an electrical signal. After analysis by the microprocessor, the screen of the terminal device is flipped through software. The realization principle is as figure 1 shown. Action1 (action 1): The Y axis (long side) of the handheld device is parallel to the direction of gravity. At this time, the handheld device is considered t...
