Share  Vision and touch employ a common strategy: To make use of both these senses, we must actively scan the environment. When we look at an object or scene, our eyes continuously survey the world by means of tiny movements; when exploring an object by touch, we move the tips of our fingers across its surface. Keeping this shared feature in mind, Weizmann Institute of Science researchers have designed a system that converts visual information into tactile signals, making it possible to “see” distant objects by touch.     Converting information obtained with one sense into signals perceived by another – an approach known as sensory substitution – is a powerful means of studying human perception, and it holds promise for improving the lives of people with sensory disabilities, particularly the blind. But even though sensory substitution methods have been around for more than fifty years, none have been adopted by the blind community for everyday use.
