Evaluation of patient´s computer input ability

In this paper, we describe a measurement and evaluation system of the computer input ability of patients with tetraplegia. We measure the position locus of the mouse cursor when a patient operates the computer using a computer input device such a ball mouse, trackball, or touch pad. After measurement, we analyzed the position locus of the mouse cursor in order to evaluate the computer input ability of patients with tetraplegia. Based on our measurement and evaluation system, it became clear that the new computer input device is useful for patients with tetraplegia.
