E-Learning For The Blind And Visually Impaired

Asma Mushakbar Paracha, Narmeen Shawoo Bawany.

The increased popularity of E-learning have made education easier and faster for many sighted users, but for their blind and visually impaired colleagues this development has been a drastic step backwards. Visualization is an increasingly important method for people to understand complex information, that is, using tables, graphs and 3D plots, etc. and also to navigate around structured information.
Computer-based visualization techniques, however, depend almost entirely on high-resolution graphics and for visually impaired users the problems of using complex visual displays are great. There are currently only limited methods for presenting information non-visually and these do not provide an equivalent speed and ease of use to their graphical counterparts. This means it is impossible for blind people to use visualization techniques, so depriving them further. The paper investigates and discusses the techniques that will allow users to feel and hear their data.
The overall objective of this research is to discuss the use of haptic technology in enhancing the access of blind and visually impaired people to E-Learning resources.

Haptic interface technology allows tangible realizations of data surfaces to be realized, providing an additional modality for data exploration and analysis. Haptic virtual reality allows a user to feel Virtual Environments (VEs) by means of haptic displays.
