Sensor evaluation for real - time pace and step detection for sonic interaction

The STSM took place from May 25 th 2010 to June 25 th 2010. The purpose was to evaluate different sensors, locations and algorithms for real-time step detection for use in sonic interaction, using both quantitative and qualitative evaluation. For the quantitative evaluation, we compare the results with a Ground Truth derived from pressure sensors in the shoes. The qualitative evaluation is done using the sonification of the heel-strikes: this allows users to hear their footsteps, as detected by the system, in real-time. A user survey polls for the accuracy of the step detection in terms of false positives, ignored steps and delay. Furthermore, the sonification had a secondary goal: do different sounds influence the gait pattern?
