Prototype of network aided multimedia biofeedback system

Abstract

Recently it has become popular to measure bio-information by using computer. Along with acceleration of CPU, many jobs, which used to be processed by hardware, now can be processed by software. The development of biofeedback system used to be relatively difficult and tended to lack generality. But recently, many less ex-pensive and powerful tools have become available, and by making use of them we can make highly sophisticated and stable biofeedback system in short term. And the rapid development of multimedia technology enables us to process feedback information into various forms. This brings us benefits in the following two respects : First, by utilizing software, we can transform the information into more comprehensible style for subjects. Secondly, by doing that, we can keep subjects' motivation high and can improve the efficiency of training. In this study, we tried to make prototype of biofeedback system, which has the following three characteristics, 1) apply the latest multimedia technologies in feedback method, 2)build client/server style network (measuring bio-information in server side and sending them to client side for feedback), 3) simple system which anybody can build easily. The performance and potential of the system, and some consideration is included.
