Perception of Graphical Virtual Environments by Blind Users via Sensory Substitution

Perception of Graphical Virtual Environments by Blind Users via Sensory Substitution

Graphical virtual environments are currently far from accessible to blind users as their content is mostly visual. This is especially unfortunate as these environments hold great potential for this population for purposes such as safe orientation, education, and entertainment. Previous tools have increased accessibility but there is still a long way to go. Visual-to-audio Sensory-Substitution-D...

Visualising graphical user interfaces for blind users

• A submitted manuscript is the author's version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published version of record.

Sensory Substitution : Perception Dedicated to Action

Paul Bach Y Rita [1] is the precursor of sensory substitutions. He started thirty years ago using visuotactile prostheses with the intent of satisfying blind people. These prostheses, called Tactile Vision Substitution Systems (TVSS), transform a sensory input from a given modality (vision) into another modality (touch). These new systems seemed to induce quasi-visual perceptions. One of the au...

Depth-To-Audio Sensory Substitution for Increasing the Accessibility of Virtual Environments

As most computerized information is visual, it is not directly accessible to the blind and visually impaired. This challenge is especially great when discussing graphical virtual environments. This is especially unfortunate as such environments hold great potential for the blind community for uses such as social interaction, online education and especially for safe mobility training from the sa...
