FINGER POINTING ACCURACY ON LEAP MOTION SENSOR.

In this short paper we present a performance analysis of the Leap Motion depth sensor solely used as a single finger pointing device. Based on the evaluation of Fitts' Law, we have examined the sensor capabilities with two groups of participants -10 moderately aged computer affine technicians and 10 elderly people with no explicit experience in handling technical devices. Results have been compared to the currently most efficient pointing device, the mouse, and show clearly, that the gap between young and old, professional and unskilled users has to be considered by HCI designers in order to create a similar and consistent good user experience.
