The Gametrak is a real 3DOF tracker, which can be used with both hands. According to the company, the system is able to calculate the exact position in 3D space, with a spatial resolution of 1 millimetre anywhere within a 3m cube around the unit, with no processor overhead or time delay (that seems quite unrealistic to me, but if they write it...)

Strings attached to the user's hands allows the system to measure the distance and angles from the base item on the ground; these information are used to calculate the x,y, and z coordinates of the hands.

Given these features, the Gametrack system could be effectively applied in post-stroke rehabilitation of the upper limb and in other computer-based programs for neurorehabilitation. In fact, the Gametrack can be easily programmed and adapted to existing applications. Further, the cost of the device is very cheap (about 30€) if compared to other virtual rehabilitation hardware.    

If any Positive Technology reader wishes to try the system for rehabilitation purposes, we would be very interested in knowing the results
