Playing progress adjustment method and device

Abstract

The invention provides a playing progress adjustment method and device. The playing progress adjustment method is used for configuring a moving device of a touch screen and includes the steps of sensing and analyzing input motions of a user on the touch screen, obtaining motion features of the input motions and judging whether the input motions are rotation operations in a specific area according to the motion features, if the answer is positive, determining the direction of the rotation operations and deviation angle change information of the rotation operations relative to a start operation point, determining the playing progress adjustment trend and the amplitude according to the direction of the rotation operations and the deviation angle change information and carrying out playing progress adjustment according to the playing progress adjustment trend and the amplitude. Single-finger rotation motions of the user can be recognized through the touch screen, and accordingly playing progress of a multimedia file can be conveniently adjusted, the user can operate the device conveniently, playing progress adjustment can be carried out according to the linear relation between rotation angles and playing progress values and continuity and sensitiveness of playing progress adjustment are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of touch screens of mobile devices, in particular to a method and device for adjusting playback progress. Background technique [0002] Touch screens have been widely used in mobile devices such as tablet computers, smart phones, and remote controls. However, existing mobile devices such as mobile phones, tablet computers, and remote controls still use traditional methods to adjust the playback progress of multimedia files such as audio files and video files. The push-button adjustment method is to adjust the playback progress of the multimedia file by pressing the physical buttons set on the above-mentioned mobile device. But such an adjustment method is very inconvenient. If the user wants to fast-forward from a certain playback process point to another playback process or rewind from a faster playback process to a slower playback process, he needs to continuously press the playback progress key or...

But such an adjustment method is very inconvenient. If the user wants to fast-forward from a certain playback process point to another playback process or rewind from a faster playback process to a slower playback process, he needs to continuously press the playback progress key or Reverse button, the operation process is very inconvenient, and the addition of physical buttons to adjust the playback process on the mobile device also affects the simplicity and aesthetics of the overall appearance of the mobile device
