Skin stretching- Perhaps it's a better way to go? While just doing some preliminary testing to see what skin stretch would fee like, it was pretty obvious that the skin stretch was more noticeable than having something poke. The reason the sharper object poking was more noticeable was because the concentrated shape stretched the skin more. But what do we use this technology for? You can stretch someone's skin, which is obvious from reading Dr. Hayward's papers, and it is evident that by manipulating someone's skin at the fingertips, you can distinguish the shape of an object? Can you stretch someone's skin in several different directions and have that relate to some sort of code? Doing so would eliminate the need to attach 5 different tactors on the user's body but what would be an intuitive protocol? For example, in military applications, if you're guiding someone, use the skin stretching tactor to provide directional cues? When you are guiding someone, what information needs to be conveyed? Direction (what angle? Forward or backward? Left or right? Navigating a curve vs. a sharp turn- how should that be conveyed?) Speed (can the person run? Walk? The speed determines the direction- if you're going fast, the sensitivity of the curvature is not as necessary) A visually impaired person is used to seeing darkness, and has more trust in navigational cues, whereas non-visually impaired people have a fear, perhaps a lack of trust? would you close your eyes and have a friend guide you? Sure, but most people would walk tentatively and not run comfortably? Has this already been done? Use skin stretching to keep track of your location? Hikers get lost- use GPS system to guide them back home safely? Guiding people by placing your hands on their shoulders?... What has prevented some of these haptic ideas from becoming a reality? Cost? Design? Public unacceptability? People are not used to using the sense of touch to navigate...navigation is done with visual and oral cues...perhaps this is why it has been difficult to introduce haptics? What do people use touch for? Manipulation of objects, maneuvering, exploration of new environments,
