Analysis of computer input operation by patients with tetraplegia

In rehabilitation medicine, the patients with tetraplegia are trained how to operate the computer as rehabilitation. It is necessary for medical staffs to evaluate the computer input ability of patients with tetraplegia. We measured the position locus of the mouse cursor when patients operate the computer using a ball mouse. In this paper, we calculate eight parameters and illustrate these parameters on a radar plot to evaluate the computer input ability of patient with tetraplegia. Using radar plot, medical staff can evaluate the computer input ability and then recommend the best computer input device for each patient
