The Exploration Of Designing And Development Of The Taijiquan (Set-pace) Hand-pushing Exercise Perceived Interaction System

Research Objective:In the recent years, a Taijiquan(fixed step) hand pushing has evolved from the recreational activity in folks to a national competitive project with great development. However, the technical system of Taijiquan(fixed step) hand pushing is complicated and the way of expression is implicit. People are hard to judge whether the application of some special techniques comply with requirements in matches. Besides, some illegal actions which are easy to be neglected might affect the result of the competition. In the research, a set of relevant electronic equipment and software system is designed to make accurate identification of these actions, and conduct automatic scoring according to the requirements of rules and regulations, thus increasing the objectiveness of the matches and accuracy of the judgment. Research Methods:The literature data method, expert interview method and survey method etc. are applied; the development venation and current situations of Taijiquan(fixed step) hand pushing are arranged and summarized; and the technical features and judgment methods of Taijiquan(fixed step) hand pushing are grasped and generalized. It mainly adopts the experimental method to designed, researched and created the perception interactive system of Taijiquan(fixed step) hand pushing. Besides, the questionnaire method is applied to collect the feedback opinions of the experiencers and experts. Research Conclusions: 1. The feet moving identification scheme is designed. The footstep displacement mainly perceives the displacement of feet by setting up film sensors at the bottom of the feet and in the surrounding regions of the feet. 2. The simultaneous displacement and non-simultaneous identification scheme is designed. The sequencing is distinguished by setting the threshold values. 3. Some hand gestures identification scheme is designed. The picking and grabbing, as well as palm striking and palm pushing are distinguished by the action time of forces. 4. A complete perception interactive system of Taijiquan(fixed step) hand pushing is designed, including hardware module and software system. Besides, the preliminary development of the software and hardware of the system is conducted according to the design. In addition, the preliminary physical products of footstep identification module have been researched and manufactured.
