Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] figure 1 It shows a schematic flow chart of the method for controlling screen rotation provided by the first embodiment of the present invention, including step S101, step S102 and step S103, which are described in detail as follows:
[0022] Step S101, acquiring the current front view angle of the smart terminal user.
[0023] In the embodiment of the present invention, the current front view angle of the smart terminal user can be acquired by first capturing the current facial image of the smart terminal user, and then analyzing the captured current facial image of the smart terminal user...

The invention is applicable to the field of mobile communication and particularly relates to a method and a device for controlling a screen to rotate. In the embodiment of the invention, the method for controlling the screen to rotate comprises the following steps of: obtaining a current facing angle of a user of an intelligent terminal; judging whether a current screen picture direction of the intelligent terminal and a current human face direction of the user of the intelligent terminal are the same or not according to the current facing angle of the user of the intelligent terminal; and if the two directions are inconsistent, rotating the current screen picture direction of the intelligent terminal to be the same as the current facing angle of the user of the intelligent terminal. According to the method provided by the embodiment of the invention, a screen image can rotate in a 360-degree direction compared with the original single 90-degree rotation in vertical and transverse directions, so that the user of the intelligent terminal can rightly face the content in all angles in a process of observing the content on the screen and the user can rightly face the content in the screen; and therefore, the method and the device disclosed by the invention bring about great convenience for the user of the intelligent terminal to utilize the intelligent terminal.
Description
technical field [0001] The invention belongs to the field of mobile communication, in particular to a method and device for controlling screen rotation. Background technique [0002] At present, most smart terminals have built-in gravity sensors. The working principle of the gravity sensor is based on the piezoelectric effect, that is, using the characteristic of voltage generated by the crystal deformation caused by acceleration inside the smart terminal, as long as the relationship between the generated voltage and the applied acceleration is calculated, the acceleration can be converted into Voltage output to complete the conversion from gravity change to electrical signal. The smart terminal with a built-in gravity sensor will automatically flip the screen when it is placed horizontally or vertically. This feature can replace the control of the four directions of up, down, left, and right when playing games. Swing can replace the direction of the simulator game to move...
