Analysis of Wireless Inertial Sensing for Athlete Coaching Support

The use of inertial sensors for distinguishing different types of users´ everyday activities was demonstrated in existing work. The sensing for sports and managed exercise (SESAME) project investigates a different aspect of on-body wireless inertial sensing: one of the major aims of the project is to evaluate whether inertial sensors are useful for detecting the smallest details of a rapidly moving (foot) motion of a sprinter, which would be useful for coaching support. In this paper, we present our on-body wireless inertial sensing system, and analyse our system in three aspects: a) a foot motion analysis using the collected inertial data of sprinters; b) the system´s physical characteristics (i.e. weight and operational behaviour); and c) the system´s wireless performances.
