In the paper we propose a novel hands-free pointing device for the disabled based on commercially available inertial sensors (XSens MTx) and evaluate its performance on twelve test subjects using multi-directional point-and-select task and experimental design adopted from [1]. In experiments throughput was chosen as a main performance parameter, with error rate being the additional parameter. Two pointing modes were tested, as well as two selection techniques. Additionally, all test subjects were given questionnaires in which they had to rate pointing device comfort and performance. Obtained results are presented and discussed.
