Abstract :
Head controls are an alternative computer interface for individuals who cannot use a standard mouse. Functional performance was observed while subjects used a head control system. The relationship between movement time and distance was described by a Fitts´ Law model with 27.3% error. The data indicate that diagonal movements take longer than horizontal or vertical movements (p=0.07)
