壓力傳感鞋及其太極拳學習系統之應用

Abstract

太極拳是一種中華文化的其中一種古代武術，拳術特色是重視動作的穩定及全身重心的變化，運行時需要全身放鬆，達到柔、軟、弱、沉、散... 等特點。現今種種研究指出太極拳是有益於身體健康，也因為如此，近幾年來，在世界各地越來越多人喜歡打太極拳。傳統學習太極拳的方式是透過看太極拳相關書籍及動作示範影片或是直接拜師，由教練親自指導動作，但是對使用者來說單單只靠上述的方法有些部分，如重心分布，依然是很難學會的，使用者還是需要花很長的時間去觀察並依靠本身的悟性去慢慢學習。 因此，我們設計了一雙壓力傳感鞋以及一套太極拳學習系統，利用擁有高低施力感測範圍的壓力感測器去量化教練及使用者的足底壓力分佈再用顏色代表施力比重的視覺回饋方式，去引導一般人更有效率的學習正確的太極拳動作及正確的動作重心分布。 在實驗部分，我們不只測試了人體對於掌控重心分布的敏感性，也 對我們的系統進行了學習效果的檢測，最後成功的證明我們系統確實 比一般傳統學習方式更有效率的提升學習成果。

Tai Chi Chuan (or TCC in short) is a famous ancient Chinese martial art. Playing TCC is good for health but hard to learn. In addition to reading the books about TCC and watching the demonstration videos, the traditional ways of learning TCC for most people are that realizing TCC taught by coach personally and then trying to do the same movements. Due to complex and several TCC actions, students often spend a long time observing and realizing. It is possible to say that learning TCC is to rely on personal insight. For instance, the plantar pressure distribution is very particular in TCC but too difficult to identify by only observing coach's movement or listening to coach's description. Therefore, to help people to learn the standard movements and standard plantar pressure distribution of movements to let students improve stably, we provide a pair of pressure sensing shoes, named“sense your feet,” with high-and-low resolution force sensors to quantize user's and standard plantar pressure distributions and a Tai Chi Chuan instruction system with interactive visual feedback to guide user the correct action of TCC. We do the pilot study of the sensitivity of plantar pressure distribution for human and then find some people are not sensitive to their plantar pressure distribution. We also evaluate our system is effective to help people to learn TCC successfully. In conclusion, the contributions of our approach are not only a pair of pressure sensing shoes suitable to wear while playing TCC, but also effective TCC instruction system.
