ABSTRACT
In the last few decades, a growing number of Electronic Orientation Aids (EOA) has been developed with the purpose of improving the autonomy of visually impaired people. However, the majority of those systems are not used by the blind due to limited usability. The main challenges to be addressed are about interaction and guidance. To address these issues, we designed a multimodal (input and output) Virtual Environment (VE) that simulates different interactions that could be used for space perception and guidance in an EOA. This platform subserves two goals: help designers to systematically test guidance strategies (i.e. for the development of new EOAs) and train blind people to use interactive EOAs, with an emphasis on cognitive mapping enhancement. In a multimodal VE, both objectives are assessed in a controlled, cost-effective, safe and flexible environment.

Enriching graphic maps to enable multimodal interaction by blind people
UAHCI'13: Proceedings of the 7th international conference on Universal Access in Human-Computer Interaction: design methods, tools, and interaction techniques for eInclusion - Volume Part IGeographical maps are by their nature inherently inaccessible to blind users since the information is conveyed mainly in a visual way. The attempt to convert all the information to an alternative modality allowing satisfactory exploration by blind ...
Multimodal augmented reality: the norm rather than the exception
MVAR '16: Proceedings of the 2016 workshop on Multimodal Virtual and Augmented RealityAugmented reality (AR) is commonly seen as a technology that overlays virtual imagery onto a participant's view of the world. In line with this, most AR research is focused on what we see. In this paper, we challenge this focus on vision and make a case ...
Evaluation of multimodal graphs for blind people
This paper introduces the development of a multimodal data visualisation system and its evaluations. This system is designed to improve blind and visually impaired people's access to graphs and tables. Force feedback, synthesized speech and non-speech ...
