Investigate how to better describe the semantic of an action

[pattacini]

This is a somewhat complex task dealing with the possibility to have a finer granularity in the description of an action, which in turn could be used to improve the verbal feedback.

[vvasco]

Given that Dynamic Time Warping (DTW) allows us to discriminate signals at different speeds (#75), we are going to use it to:

• provide a feedback on the speed of the performed movement (e.g. move faster or slower)
• align skeletons and provide a feedback on the position (e.g. move right hand up)
