User Interface for Visually Impaired People

User Interface for Visually Impaired People

The research work deals with the design and implementation of Speech recognition device using Raspberry Pi for essential usage to visually impaired people. Now a day’s blind people are increasing enormously so, the main objective of the research is to provide a simple, cheap, friendly user, and compact device for visually impaired people to use multimedia applications of operating system like t...

Visualization Learning for Visually Impaired People

Virtual Environments (VE) are mainly visual experiments that exclude visually impaired people. In this paper we present an application that should allow almost everybody to “see” or at least to perceive 3D shapes. We will first describe the mandatory aspects of such an application, the tests we made and finally conclude by the results we obtained with geometrically basic shapes that are very pr...

Open source technologies for visually impaired people

We describe two open source applications which we have experienced as very useful aids for the integration of people suffering from visual impairments, from hypovision to actual blindness. The first application is based on speech synthesis and has been experienced by disabled university students. The second experience is oriented to schoolchildren with low residual vision, and it provides their...

Spatial Haptic Orientation for Visually Impaired People

Is it possible to show space relations to blind people ? Techniques and experiments described in this article explore several ways of accessing spatial information by blind people using one point forcefeedback device. The study focuses on two techniques supporting an orientation in buildings. Preliminary results show that a wider spectrum of different techniques suitable for blind people is nee...
