Engineers from the University of New South Wales (UNSW) have claimed the invention of a soft wearable device they say simulates the sense of touch. Haptic technology mimics the experience of touch by stimulating localised areas of the skin in ways that are similar to what is felt in the real world through force, vibration, or motion. "When we do things with our hands, such as holding a mobile phone or typing on a keyboard, all of these actions are impossible without haptics," Scientia lecturer and director of the UNSW Medical Robotics Lab Dr Thanh Nho Do said. "The human hand has a high density of tactile receptors and is both an interesting and challenging area to encode information through haptic stimulation, because we use our hands to perceive most objects every day." He said there are many situations where the sense of touch would be useful, but is impossible.
