“…For selecting an object, the user has to press a switch at the right time. Brewster et al [1996] showed that added auditory feedback supported the scanning rhythm and helped the users in predicting the right time for pressing the switch for selection, thus improving the performance. Seifert [2002] studied feedback in gaze interaction by comparing 1) continuously shown gaze cursor, 2) discrete feedback with highlighting the target under focus, and 3) no visible feedback for the gaze position.…”

Eye typing provides means of communication especially for people with severe disabilities. Recent research indicates that the type of feedback impacts typing speed, error rate, and the user's need to switch her gaze between the on-screen keyboard and the typed text field. The current study focuses on the issues of feedback when a short dwell time (450 ms vs. 900 ms in a previous study) is used. Results show that the findings obtained using longer dwell times only partly apply for shorter dwell times. For example, with a short dwell time, spoken feedback results in slower text entry speed and double entry errors. A short dwell time requires sharp and clear feedback that supports the typing rhythm.

“…Speech includes recorded voice or synthetic voices generated with text-to-speech applications. Associating non-speech sounds (auditory icons and earcons) with events has been shown to improve the interaction of graphical human-computer interfaces (Gaver et al, 1991;Blattener et al, 1992;DiGiano et al, 1993;Brewster et al, 1996). Auditory icons are everyday sounds can intuitively be associated with system events (Gaver et al, 1991;Gaver, 1993a,b), while earcons are abstract, musical tones that can be used in structured combinations to indicate audio messages (Blattner et al, 1989;Brewster, 1998).…”

This work is concerned with the issue of user performance with audio interfaces. We examine how people perform when assigned with simple purely audio tasks. We de ne 'user performance' as the ratio of correct score divided by the time to complete the task. A test was devised to examine how the user cognitive style classi cation is related to user performance when dealing with audio tasks. Performance was signi cantly different between all tasks except for two cases. Subjects performed best where the level of cognitive demands placed on them were low and prefer tasks that use 'Speech', rather than 'Non-Speech'. Cognitive style was not found to be a signi cant factor in uencing performance where all subjects performed well, but subjects' Verbal-Imagery classi cation was found to be a signi cant factor for the more complex tasks.

“…In [2], the block-row-column based scanning is augmented with auditory signals based on the fact that temporal perception is more sensitive to auditory input than visual input. Although preliminary results show that children enjoy auditory input, quantitatively it is not proved to enhance the performance.…”

Persons with severe motion impairment like biplegics, quadriplegics etc. face difficulty in accessing computerbased systems since they can not use conventional computer access devices like mouse or keyboards. Alternate access mechanisms consisting of scanning and access switches have been developed for such users. One problem with scanning based access mechanism is that it slows down the user-computer interaction significantly leading to user frustration and fatigue that in turn results in further drop in user performance. To address this issue, this paper presents a scanning mechanism that adapts itself according to the user's requirements. This adaptation leads to an improvement in user performance. The performance improvement of the proposed adaptive scanning mechanism is demonstrated in the paper with user testing results.
