The SWANS (Semantic Web Accessibility Network Services) is a research project which addresses physical immobility issues of visually impaired (VI) people, exploring ways of transforming their lives using Semantic Web Services (SWS). This paper explores the development process of an innovative prototype: SWANS-TAW (SWANS-Travel Assistant Wireless). This prototype was designed, developed and deployed using pocket PC 2003 second edition Emulator available in the Microsoft Visual Studio 2005. SWANS’ services and contemporary wireless assistive technologies were used to assist VI users. The prototype was examined in order to assess how confident and independent VI users are in their daily lives. Our prototype can help them to explore new opportunities for education, employment and leisure, not only through independent, but also productive living. This research was conducted in collaboration with the Cambridge On-line Pathways Project.
A qualitative approach was used to evaluate this innovative prototype. This study was carried out through direct observations and informal interviews conducted over a year. The sample size consisted of fifteen people. In this sample one participant was color blind, three were blind and the remaining eleven had low vision. All participants were adults.
The study found that more than 60 percent of the participants were confident in dealing with their physical immobility issues using this new prototype; less than 40 percent of the participants could not manage to use this prototype due to the navigation problems caused by the small screen. This prototype could prove to be a model application for the wireless assistive technology and the web publishing industry.
