Method for coding touch data as video stream to save and transmit

Abstract

The invention relates to a method for coding touch data as a video stream to save and transmit. The method is characterized by comprising the following steps: 1) converting the touch data on each acquisition point of a three-dimensional human body at different moments into two-dimensional touch image data arranged in timing sequence; 2) coding the obtained two-dimensional touch image data arrangedin timing sequence by using a conventional video compression method to obtain touch stream data for saving and transmitting the touch data or sharing the touch data among different systems; 3) decompressing the obtained touch stream data by using the conventional video compression method to obtain a two-dimensional touch image data sequence arranged in the timing sequence; and 4) performing the touch reproduction on the human body according to the obtained two-dimensional touch image data sequence arranged in the timing sequence. By using the method disclosed by the invention, the data compression and real-time stream transmission problem of the touch data in the network transmission process is fundamentally solved, so that the method can be extensively applied to the saving and transmission of the touch data.

Description

technical field [0001] The invention relates to a method for storing and transmitting data, in particular to a method for encoding tactile data into a video stream for storing and transmitting. Background technique [0002] The sense of touch is a sense that humans use to perceive the shape and material of objects. When people watch immersive video or virtual reality content, they often reach out and want to touch the objects in it. It can be seen that the sense of touch is very important for human beings. a sense of. [0003] Now, more and more attention has been paid to tactile reproduction in the field of video playback or virtual reality. Through force feedback gloves or force feedback clothing, people can personally perceive the shape and material of objects while watching. Tactile reproduction is to record the tactile data that needs to be applied to the human body through force feedback gloves or force feedback clothing at the current moment according to the content ...

AI Technical Summary

Problems solved by technology

This requires simultaneous transmission of tactile data while saving and transmitting video data and audio data. However, most systems currently save and transmit tactile data through custom formats, resulting in tactile data that cannot be easily shared between systems. At the same time, the existing custom formats have not considered the problems that must be solved in network transmission, such as data compression and real-time streaming transmission.
