The right of blind people to access the Internet is simply ignored in many countries because Web pages have been designed for normal people. As a result, many blind people are not enjoying the benefits of the Internet and the improvement in the quality of life that Internet use can bring. In order for visually impaired persons to surf the Internet, it is necessary to develop a special humancomputer interface (HCI) system. This paper presents the design of a Web project for the blind. The aim of this research is to develop a new HCI model and an associated computer system for visually impaired people so that they can browse the World Wide Web via Internet. An assessment of the potential of a wide range of applications and their impact are also presented.
We present two studies that have advanced the design of brain-body interfaces for use in the rehabilitation of individuals with severe neurological impairment due to traumatic brain injury. We first developed and evaluated an adaptive cursor acceleration algorithm based on screen areas. This improved the initial design, but was too inflexible to let users make the most of their highly varied abilities. Only some individuals were well served by this adaptive interface. We therefore developed and evaluated an approach based on personalized tile layouts.The rationales for both designs are presented, along with details of their implementation. Evaluation studies for each are reported, which show that we have extended the user population who can use our interfaces relative to previous studies. We have also extended the usable functionality for some of our user group. We thus claim that personalized tiling with discrete acceleration has allowed us to extend the usable functionality of brain-body interfaces to a wider population with traumatic brain injury, thus creating new options for neurorehabiliation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
