Sensory perception. (haptics).(SmartTouch developed at University of Tokyo)(Brief Article)

A new feedback system that converts visual data into skin sensations has been introduced by developers at the University of Tokyo. Called SmartTouch, the new haptics-based device combines a thin electro-tactile display with sensors mounted on the skin so the wearer can "touch" visual information. To create complex tactile sensations. SmartTouch produces an electrical current in the various types of receptors in the skin to induce nerve activity. When the sensors come in contact with objects shown on the display, SmartTouch changes the electric field distribution at the skin surface, taking into account the different placement of the skin's sensory nerves to create ...
