Modular Collaborative Sensing and Feedback Units for Smart Exercising

Smart exercising is a new trend in which various physical activities are monitored by so-called smart devices, and in some cases even give limited advice. This paper proposes a modular system composed of individual sensing and feedback units that communicate in a network in order to improve timing related exercise parameters in the case of athletes or committed individuals. The main contribution is a system that gamifies the workout by providing a series of targets that must be reached by hand/foot either in a randomized order or a predetermined one, as specified by a coach. The wireless nature of the system allows for multiple arrangements suitable for a large variety of exercises. All stages from conception, modelling, manufacturing and preliminary testing are presented and discussed.
