Information technologies are increasingly helping to integrate and socially include people with visual disabilities. Computing technologies have contributed grandly to attain this goal through innovative techniques and applications. Virtual environments, I/O interfaces, and sound based applications altogether with usability and cognitive impact studies are(More)
This work presents an evaluative study on the usability of a haptic device together with a sound-based video game for the development and use of orientation and mobility (O&M) skills in closed, unfamiliar spaces by blind, school-aged children. A usability evaluation was implemented for a haptic device especially designed for this study (Digital Clock(More)
Science learning for blind people is limited. For a variety of reasons there is a very low emphasis on science learning for such users, especially those from deprived communities. We have designed, implemented and evaluated the usability of AudioNature, an audio-based interface implemented for pocketPC devices to assist with science learning in users with(More)
We present the design, development and an initial study changes and adaptations related to navigation that take place in the brain, by incorporating an Audio-Based Environments Simulator (AbES) within a neuroimaging environment. This virtual environment enables a blind user to navigate through a virtual representation of a real space in order to train(More)
We present the design, development and initial cognitive evaluation of an Audio-based Environment Simulator (AbES). This software allows a blind user to navigate through a virtual representation of a real space for the purposes of training orientation and mobility skills. Our findings indicate that users feel satisfied and self-confident when interacting(More)
In this study we evaluate how the use of audio-based technology can facilitate school integration of blind learners through the interaction with a science videogame. This experience consisted of designing and implementing The Natomy's Journey Game to be played by blind and sighted middle school students. The use of the videogame and its impact on the(More)
