Feasibility Study of Hand Motion Analysis by the Leap Motion Sensor

This paper presents the results of a feasibility study for the use of the infrared sensor LeapMotion for hands motion analysis in clinical evaluation. A system was developed to allow patients with muscular weakness to use this sensor. This system was used on 2 patients affected by spinal muscular atrophy. The results showed that the LeapMotion is not sufficiently robust or accurate for clinical assessment. In addition, the proposed system installation complicates the process. More trials with specific users and profiles should be realized to refine and improve those results.
