Article describes a system called the Vocal Joystick, which allows the user to continuously control the mouse cursor by varying vocal parameters such as vowel quality, loudness, and pitch. Evaluations were conducted to characterize expert performance capability of the Vocal Joystick and to compare novice user performance and preference for the Vocal Joystick and two other existing speech-based cursor control methods. The results show that Fitts' law is a good predictor of the speed-accuracy tradeoff for the Vocal Joystick, and suggests that the optimal performance of the Vocal Joystick may be comparable to that of a conventional hand-operated joystick. Novice-user evaluations show that the Vocal Joystick can be used by people without extensive training, and that it presents a viable alternative to existing speech-based cursor control methods.
