Imaging of computer input ability for patient with tetraplegia

We describe a measurement and evaluation system of the computer input ability of patients with tetraplegia. We measured the position locus of the mouse cursor when a patient operates the computer using a ball mouse. After measurement, we analyzed the position locus of the mouse cursor in order to evaluate the computer input ability of patients. Then we proposed a system for the evaluation of computer input ability of patients with tetraplegia. It enables the medical staffs to evaluate the computer input ability of patients and to choose the best computer input device for each patient.
