This article presents research on making schoolbook illustrations accessible for students with visual impairment. The MaskGen system was developed to interactively transpose illustrations of schoolbooks into tactile graphics. A methodology was designed to transpose the graphics and prepare them to be displayed on the STReSS2, a refreshable tactile device.(More)
This paper describes the development of 3D network applications with force feedback for and with hospitalized children. These applications are built on an innovative multimodal platform which includes networked 3D graphics, sound and force feedback. One goal of this research is to improve the life quality of children isolated in sterile rooms during their(More)

This case study explains how we used two computer-supported cooperative work (CSCW) frameworks to define collaboration-related user requirements and experience attributes for Retail.Me, a new retail planning solution currently being designed at JDA Software. Our focus is on how this kind of framework can be used in industry and if one particular framework(More)

We investigate gains in user appreciation and performance when the level of detail of tactile graphics is dynamically altered either at the press of a button or automatically, as a function of exploration speed. This concept was evaluated by asking 9 visually impaired participants to perform hierarchical spatial search tasks in a concert hall illustration.(More)
The synthesis of epibatidine derivatives modified at the 2-position of the pyridine or pyrimidine rings by reactive functions are described for potential irreversible site-directed coupling reactions on cysteine mutants of neuronal nicotinic acetylcholine receptors. An improved synthesis of the 7-azabicyclo[2,2,1]hepta-2,5-diene key intermediate has been(More)
