“We conducted a 2.5 week longitudinal study with five motor impaired (MI) and four non-impaired (NMI) participants, in which they learned to use the Vocal Joystick, a voice-based user interface control system. We found that the participants were able to learn the mapping between the vowel sounds and directions used by the Vocal Joystick, and showed marked improvement in their target acquisition performance. At the end of the ten session period, the NMI group reached the same level of performance as the previously measured "expert" Vocal Joystick performance, and the MI group was able to reach 70% of that level. Two of the MI participants were also able to approach the performance of their preferred device, a touchpad. We report on a number of issues that can inform the development of further enhancements in the realm of voice-driven computer control.”

“Mouse control has become a crucial aspect of many modern day computer interactions. This poses a challenge for individuals with motor impairments or those whose use of hands are restricted due to situational constraints. We present 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. A survey of existing cursor control methods is presented to highlight the key characteristics of the Vocal Joystick. 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. Our results show that Fitts' law is a good predictor of the speedaccuracy 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.”
