“…Empirical user studies, if conducted at all, generally do not include users with motion disabilities. Mouse-replacement systems that have been tested with people with motion impairments are Sina from Spain [34,54] and Nouse from Canada [33]. For other promising research systems [55][56][57][58][59][60], tests with users with motion impairments have not been conducted but are reportedly planned.…”

The graphical user interfaces of popular software are often inaccessible to people with severe motion impairments, who cannot use the traditional keyboard and mouse, and require an alternative input device. Reaching for buttons and selecting menu items, in particular, can be difficult for nonverbal individuals with quadriplegia, who control the mousepointer with head motion via a mouse-replacement system. This paper proposes interaction techniques that can be used with mouse-replacement systems and enable the creation of accessible graphical user interfaces. To illustrate these techniques, the paper presents an image editing application, named Camera Canvas, that uses a sliding toolbar as its universal menu controller. The parameters of the toolbar automatically adapt to the movement abilities of the specific user. Individuals with and without disabilities and of a variety of ages were observed using Camera Canvas. It was found that the developed techniques worked across many different movement abilities and experience levels. Then, it was investigated how such techniques could be used to ''retrofit'' existing Windows applications with new graphical user interfaces. A tool called Menu Controller was created that can automatically re-render the menus of some existing applications into adaptive sliding toolbars. Menu Controller enables users of mouse-replacement systems to select menu entries that were otherwise inaccessible to them.

“…Kjeldsen [21] and Kim and Ryu [19] mentioned plans to test the proposed interfaces with users with motion impairments. Manresa et al [27] tested an interface developed by Varona et al [39] with 10 users with movement disabilities. Interface tracks multiple features on a subject's face, such as the nose, eyes, and mouth.…”

“…They can also allow him to type short messages simply by looking at characters on a virtual keyboard. Gaze direction is typically determined using electro-oculography (EOG) (Lileg et al, 1999) or computer vision techniques (Varona et al, 2008;Markand, 1976). Unfortunately, many eye-tracking systems suffer from the Midas Touch problem (Jacob, 1991).…”

Abstract:Recent advances in electroencephalography (EEG) and electromyography (EMG) enable communication for people with severe disabilities. In this paper we present a system that enables the use of regular computers using an off-the-shelf EEG/EMG headset, providing a pointing device and virtual keyboard that can be used to operate any Windows based system, minimizing the user effort required for interacting with a personal computer. Effectiveness of the proposed system is evaluated by a usability study of nonhandicapped users, indicating high user satisfaction and decreasing learning curve for completing various tasks. A short demonstration movie of the proposed system can be seen in the link provided.
