Web Accessibility: Factors Enabling the Visually Impaired to Using Websites

This paper applies and extends the Unified Theory of Acceptance and Use of Technology (UTAUT) to understand website usage among visually impaired users. We propose two new constructs, web accessibility and vision impairment level, and suggest that these constructs moderate the effects of UTAUT constructs on behavioral intention and actual usage behavior of visually impaired users. We present a plan to empirically test our proposed hypotheses using a field survey of visually impaired users regarding their usage of a website that conforms to accessibility guidelines. This paper contributes to research by drawing attention to the disabled population – an underserved area of information systems research, by identifying relevant constructs that apply in this unique context, and by elucidating how these constructs influence their technology usage

Touchable Online Braille Generator

A prototype of a touchable online Braille generator has been developed for the visually impaired or blind using force feedback technology, which has been used in video games for years. Without expensive devices, this prototype allows blind people to access information on the Web by touching output Braille displays with a force feedback mouse. The data collected from user studies conducted with blind participants has provided valuable information about the optimal conditions for the use of the prototype. The end product of this research will enable visually impaired people to enjoy information on the Web more freely

Force feedback textual and graphic displays for the blind

Using the force feedback technology, which has been used in video games for years, prototypes of touchable online Braille generator and touchable online graphical display have been developed for visually impaired or blind users. Without expensive devices, these prototypes let blind people access information on the web by touching the output Braille displays or by scrolling over tactile graphical displays with a force feedback mouse. User studies have been conducted with visually impaired people and the data collected provide valuable information about the optimal conditions for these prototype force feedback displays, such as how strong the force should be and how big the Braille dots should appear. The end product of this research will enable visually impaired people to enjoy information on the web, including images, more freely
