Method for inducting neck rotation through Doppler effect

Abstract

The invention discloses a method for inducting neck rotation through the Doppler effect. The method includes the steps that a loudspeaker sends out sound waves at a fixed frequency, microphones on the two sides receive the sound waves, data of the sound waves are input to a controller for analysis, changes of the frequency due to the Doppler effect are utilized to induct rotation of the neck, through a sound wave analyzer, the direction of the rotation of the neck can be analyzed, and the data are input to a computer or a television terminal to achieve human-machine interaction. By means of the method, a better effect of inducting the neck rotation in reference to accuracy and real-time performance is achieved, and human-machine interaction of for a user is better embodied.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a method for sensing neck rotation by using the Doppler effect. Background technique [0002] Human-computer interaction technology has experienced decades of development. At present, the use of graphical interface operations is dominant. A typical example is that we use the Windows operating system to conduct human-computer interaction through keyboards and mice. However, this interaction method is being affected Constant criticism, while new interactive technologies are still being developed, researched and popularized. It can be considered that the future human-computer interaction will mainly be based on the natural human-computer interaction mode. For example, people can realize human-computer interaction through gestures, voice or other movements of human body parts. [0003] At present, there is no invention of neck or head rotation detection in the pri...

Problems solved by technology

Another problem is that there are precision problems in digital image processing, such as when two heads appear in a video, how does it deal with it, how does it accurately locate the head position, when the video quality is not high (there is high noise) or the head What to do if the head turns too fast?

These problems directly reflect the poor robustness of the method in technology one, so the present invention proposes another method to realize the detection method of neck rotation
