Problems solved by technology

[0003] At present, a mainstream behavior recognition is based on images and videos. Analyzing and recognizing human behaviors through images or videos can obtain very accurate recognition results. However, this technology has high requirements for ambient light and background. It is relatively easy for large movements (such as running and jumping), but it is difficult to accurately identify small movements such as finger movements and body shaking
[0004] Another behavior recognition technology is based on the acceleration sensor, which can feel the acceleration of the object in three-dimensional space, so as to judge the behavior of the actor. However, the acceleration sensor can accurately recognize small movements, but the recognition of large movements is not so accurate. If the number of sensors is increased, the accuracy can be improved, but due to the large amount of data, the transmission is inconvenient
