“…It would also not suffice to evaluate the system only with people who do not have a targeted disability, which happens unfortunately often in assistive technology research [2,3,5,16]. Such choices could be likened to a hypothetical scenario in which the inventor of the violin decided to test his new instrument by having people with no musical training play with it for half an hour.…”

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.

“…The performance of NVVI is usually lower than that of traditional input methods, e.g., a mouse or a keyboard, but it is still sufficient for cases when no alternative is available. Moving the mouse using NVVI is about three times slower [7], and the NVVI-emulated keyboard can yield type rates up to about 25 characters/min [3].…”

Nonverbal vocal interaction (NVVI) is an input modality by means of which users control the computer by producing sounds other than speech. Previous research in this field has focused mainly on studying isolated instances of NVVI (such as mouse cursor control in computer games) and their performance. This paper presents a study with 36 elderly users in which basic NVVI vocal gestures (commands) were ranked by their perceived fatigue, satisfaction, and efficiency. The results of this study inspired a set of NVVI gesture design guidelines that are also presented in this paper.

“…Longitudinal studies have also been carried out with users with MIs to evaluate alternative input mechanisms. Mahmud et al [24] conducted a comparative longitudinal study of two voice-based cursor control systems to get better understanding of novice users' experience over time. Ten participants were recruited for a longitudinal experiment over five consecutive days.…”

Longitudinal Study of Two Virtual Cursors for People With Motor Impairments: A Performance and Satisfaction Analysis on Web Navigation

The lack of dexterity in the upper limbs of people with motor impairments may prevent the use of standard pointing devices, such as mice, to access graphical user interfaces. In these cases, pointing and clicking are usually performed by means of alternative devices such as joysticks, trackballs or standard keyboards. However, target acquisition can still be challenging for this group of people due to their physical condition. Based on previous works, we developed two virtual cursors: the novel cross cursor and the standard area cursor. They are devoted to assist two different groups of users with link selection within web pages: keyboard-only users, and joystick and trackball users, respectively. Both virtual cursors have been evaluated and compared with the original unassisted cursor in a longitudinal study. Eight people with motor impairments participated in an unsupervised experiment from their own personal computers at home. For a period of six weeks, each participant used both a virtual cursor and the original unassisted cursor to freely navigate the Web, and to perform predefined target acquisition tasks. Interaction data was automatically logged throughout the study along with subjective assessments concerning the usability of the virtual cursor being tested. Results show significant improvements for both virtual cursors in six of the seven cursor parameters studied, albeit with performance variations between some participants. The virtual cursors were extensively used for free web navigation and in their subjective assessments both were positively endorsed by participants who also put forward improvement suggestions for future developments.
