The Heidelberg Tactile Vision Substitution System
نویسندگان
چکیده
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 from a computer. The device has been tested with 6 blind and 4 sighted subjects.

Teaching and research in integrated microelectronics
In this paper we present a concept to train physics students in the field of integrated sensor design realized at the faculty of physics and astronomy at Heidelberg University (Germany). A laboratory for design and test of integrated sensor chips has been set up and a course program for physics students has been introduced. The work of the laboratory is illustrated by the presentation ofa proje...
متن کاملSensory substitution using tactile pin arrays: Human factors, technology and applications
Tactile arrays use a matrix of individually controllable elements to present spatial and temporal patterns of cutaneous information. Early devices of this type were in the field of sensory substitution to replace vision or hearing for users with a sensory impairment. Many advances have been made due to the appropriation of tactile displays for telerobotics and virtual reality, to represent phys...
متن کاملSensory 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...
متن کاملSensory Substitution and Augmentation Workshop Report
This report highlights and explores five questions that arose from the workshop on sensory substitution and augmentation at the British Academy, March 26 th through 28th, 2013. 1. Does sensory substitution generate perceptual or cognitive states? Sensory substitution devices (SSDs) deliver information about the environment normally perceived through stimulation in one sensory modality (the " su...
متن کاملTactile-auditory shape learning engages the lateral occipital complex.
Shape is an object property that inherently exists in vision and touch, and is processed in part by the lateral occipital complex (LOC). Recent studies have shown that shape can be artificially coded by sound using sensory substitution algorithms and learned with behavioral training. This finding offers a unique opportunity to test intermodal generalizability of the LOC beyond the sensory modal...
