Animated tactile sensations in sensory substitution systems
We have designed and made a computer controlled, electrocutaneously stimulated, tactile display to assist in the interpretation of complex graphical data. This paper covers the initial experiments with the tactile display, complementing the standard VDU. An animated vector was generated and the absolute tactile directional acuity of the observers was measured. Consideration is given as to how t...
متن کاملVisuo-auditory sensory substitution for mobility assistance: testing TheVIBE
Although the principle of vision sensory substitution has been validated for over thirty years, its potential benefit for visually impaired people still remain largely untapped. The existing devices appears inefficient with respect to the actual problems impairing the daily life of visually impaired subjects. Recent advances in the comprehension of the signal processing in the visual system and...
متن کاملA Tactile Communication System for Navigation
A vibrotactile display for use in navigation has been designed and evaluated. The arm and the torso, which offer relatively large and flat surface areas, were chosen as locations for the displays. The ability of subjects to identify patterns of vibrotactile stimulation on the arm and torso was tested in a series of experiments using the vibrotactile displays. A variety of patterns of stimulatio...
متن کاملAging and Sensory Substitution in a Virtual Navigation Task
Virtual environments are becoming ubiquitous, and used in a variety of contexts-from entertainment to training and rehabilitation. Recently, technology for making them more accessible to blind or visually impaired users has been developed, by using sound to represent visual information. The ability of older individuals to interpret these cues has not yet been studied. In this experiment, we stu...
متن کاملNavigation with a sensory substitution device in congenitally blind individuals.
Vision allows for obstacle detection and avoidance. The compensatory mechanisms involved in maintaining these functions in blind people using their remaining intact senses are poorly understood. We investigated the ability of congenitally blind participants to detect and avoid obstacles using the tongue display unit, a sensory substitution device that uses the tongue as a portal to the brain. W...
