This paper describes improved methods of web access for the visually impaired. Some A few web access systems for the visually impaired have already been developed and are widely used. The improvements described in this paper are in two areas. The first is a fastest mean of jumping from the current sentence position into desired sentence position within web pages. The second is a facility for searching for sentences that have been updated since a previous viewing. User testing was carried out, and the two facilities were found to reduce not only the web page access time but also the user's mental workload.
Swell paper had been widely used to confirm graphical representation for the visually impaired. However, most tactile graphs on such paper were created by people with normal vision, who, in most cases, do not fully understand how to translate the visual aspects of a graph into a representation that the visually impaired can grasp. This paper describes a graph presentation system for translating original data sequences of electronic documents into the graph presentation. This system generates graphical representation in a tactile form. Users can touch a pin array and get a rough image of the tactile graph, and iterate graph magnification to confirm the details of the graph. They can also confirm each plotted value with auditory feedback. Experiments show that users can perceive not only simple graphs, but also complex graphs like a stock chart. Subjects were able to perceive not only maximum and minimum values, but also statistical trends of the graphs.
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.
