Screen control method and device

Abstract

The disclosed embodiment relates to a screen control method and device and belongs to the field of sound wave imaging. The method comprises the steps: transmitting a detection sound wave signal to the upper part of the screen through a sound wave transmitting component; generating an operation object image according to an echo signal received by a sound wave receiving component, wherein the echo signal is a returned sound wave signal when the detection sound signal arrives at an operation object; identifying an operation object action of the operation object according to the operation object image; controlling a preset operation control displayed on the screen to respond to the operation object action, wherein the preset operation control is used for selecting the specified display content in the screen. The method has the advantages that it is realized that various operations are performed on the screen by using a virtual operation control instead of a finger, so that a user can control the entire screen by means of a single-handed finger action when the user cannot control a mobile device with both hands, and the control efficiency of the user to the screen is improved; and meanwhile, the screen display content in the control process is not affected, and the screen display effect is ensured.

Description

technical field [0001] The present disclosure relates to the field of acoustic wave imaging, in particular to a screen control method and device. Background technique [0002] With the continuous development of screen display technology, in order to achieve better display effects, more and more mobile devices are beginning to be equipped with large-size touch screens. [0003] However, due to the limited range of single-handed touch control, users often need to use both hands to perform touch operations on the controls located on the edge of the touch screen when performing touch operations on large-screen mobile devices. , such as in a crowded bus or subway, causing inconvenience to users. Contents of the invention [0004] Embodiments of the present disclosure provide a screen control method and device, and the technical solution is as follows: [0005] According to the first aspect of the embodiments of the present disclosure, there is provided a screen control method...
