Tactile Substitution for Vision

Sensory Substitution (SenSub) is an approach that allows perceiving environmental information that is normally received via one sense (e.g., vision) via another sense (e.g., touch or audition). A typical SenSub system includes three major components: (a) a sensor that senses information typically received by the substituted modality (e.g., visual), (b) a coupling system that can process the sen...

Tactile Vision Substitution with Tablet and Electro-Tactile Display

We developed a device that converts visual information on a tablet into tactile information on the fingertip. To achieve this we mount optical sensors and a tactile display on the fingertip. Our first prototype using a vibrator for each finger revealed that it was difficult to recognize the information of the display, mainly because of its low resolution. We addressed this limitation in our sec...

The Heidelberg Tactile Vision Substitution System

We have built and operated a tactile vision substitution system based on 48 piezoelectric actuators assembled in a movable tactile output unit. The unit can be positioned at any location on a two dimensional surface to explore the line structure of a virtual image. This virtual tactile display (VTD) receives data either from camera systems equipped with suitable image processing capabilities or...

Handheld Device for Substitution from Vision to Audition

Sensorial substitution has great potential in rehabilitation, education, games, and in the creation of music and art. Current technologies allow us to develop sensorial substitution and sonification systems that would not have been imaginable two decades ago. It is desirable to let a large audience use and test sonification systems to provide feedback and improve their design. Handheld devices ...
