The development of an interactive low-cost system for executing tailored upper limb rehabilitation exercises based on game-based Virtual Environments (VEs) is presented. The distinct features of such exercises demand online measurements of point contact with continuous force sensing, as well upper limb kinematics over a large range within the VEs. To meet such requirements, our proposal accounts for an open architecture system consisting of a custom-made 68 × 122 cm touch panel equipped with 26 × 47 (1222) contact and force sensor units based on Velostat, a low cost piezoresistive material. A VE for performing customized reaching exercises runs in Unity3D and Kinect V2 provides biomechanical data points, overall, running on a unique clock that synchronizes all processes. In this way, score, time, limb position, contact and force are processed online to determine the state and progress of patients' motor function. A user evaluation involving twenty-four healthy people between 18 and 59 years old was conducted to assess, on one hand whether the system elicits natural and appropriate engagement of upper arm movements and contact with virtual objects, and on the other hand how such interaction affects intrinsic motivation, experience and workload. Results show that detecting contact point and applied force induce appropriate upper limb movements at the expense of low levels of frustration and mental demand, in contrast to high levels of interest/enjoyment and perceived competence. Therefore, the proposedsystem stands for a promising low cost tool for conducting upper limb motor rehabilitationexercises. [ABSTRACT FROM AUTHOR] |
