Problems solved by technology

The direction of the line connecting the eyes and the direction of the line connecting the hands are parallel and form an angle α with the horizontal direction. figure 1 In C, α is greater than 45 degrees. At this time, the user expects the screen orientation to be displayed on the horizontal screen, but according to the detection result of the gravity sensor, it is displayed on the vertical screen, and the direction switching is wrong.

Abstract

A method for controlling a screen orientation for an electronic device is provided. The method comprises generating a sensing signal when an edge of the electronic device is held by a user, determining a screen display mode according to the sensed signal, determining a direction of a gravity vector from a center of gravity of the electronic device, determining a right-side-up display orientation according to the determined direction of the gravity vector, and displaying a screen in the right-side-up orientation under the determined screen display mode. An electronic device using the method for controlling the screen orientation is also provided.

Description

technical field [0001] The invention relates to an electronic device and a human-computer interaction method thereof, in particular to an electronic device and a screen rotation control method thereof. Background technique [0002] At present, various portable electronic devices on the market, such as tablet computers, mobile phones, digital photo frames, etc., mostly have a gravity sensor, which is used to sense the gravitational acceleration of the electronic device. By detecting the gravitational acceleration, the electronic device can determine its own rotation direction, thereby controlling the screen image to switch between landscape and portrait display modes, so as to obtain a display direction more suitable for the user. However, this method of using the gravity sensor to detect the rotation direction of the electronic device to switch between the horizontal and vertical screens is only applicable to situations where the user is standing or sitting flat.
