Icchp Keynote: Designing Haptic Interaction For A Collaborative World

The design of haptic interaction for blind users of a large tactile display capable of multitouch input may face a design barrier. Visual media and their modalites have to be mapped to tactile graphics and audiohaptic modalities due to the low resolution. We present the work of the Hyperbraille project on understanding the limitations of current screenreaders, implementation of a modular Braille window system merging multiple tactile views through Add-Ins, and report about the main findings of some of the evaluations related to reading Braille and gestural input.
