Data transmission method and device for real-time recognition of wrist mouse gestures

The invention discloses a data transmission method for real-time recognition of wrist mouse gestures. The data transmission method comprises the following steps: (1) sampling data of multiple channels are subjected to adaptive quantization coding respectively; 2) counting the occurrence frequency of the result to obtain a mapping code table and remapping the mapping code table; 3) longitudinally carrying out lossless compression on each channel result; 4) performing transverse lossy compression on the data with time correlation; and 5) carrying out longitudinal lossless compression on the data with spatial correlation. According to the method, time-related data is subjected to lossy compression, and space-related data is subjected to lossless compression. Under the conditions of small data volume and real-time compression, the accuracy and real-time performance of data transmission are ensured, the final compression rate is about 13%, and the problems of data transmission bandwidth and real-time performance i
