Skinput The Human Arm Touch screen

Abstract
Devices with significant computational power and capabilities can now be easily carried on our bodies. However, their small size typically leads to limited interaction space (e.g., diminutive screens, buttons, and jog wheels) and consequently diminishes their usability and functionality. Since we cannot simply make buttons and screens larger without losing the primary benefit of small size, we consider alternative approaches that enhance interactions with small mobile systems. One option is to opportunistically appropriate surface area from the environment for interactive purposes. For example, it describes a technique that allows a small mobile device to turn tables on which it rests into a gestural finger input canvas. However, tables are not always present, and in a mobile context, users are unlikely to want to carry appropriated surfaces with them (at this point, one might as well just have a larger device). However, there is one surface that has been previous overlooked as an input canvas and one that happens to always travel with us: our skin. Appropriating the human body as an input device is appealing not only because we have roughly two square meters of external surface area, but also because much of it is easily accessible by our hands (e.g., arms, upper legs, torso). Furthermore, proprioception – our sense of how our body is configured in three-dimensional space – allows us to accurately interact with our bodies in an eyes-free manner. For example, we can readily flick each of our fingers, touch the tip of our nose, and clap our hands together without visual assistance. Few external input devices can claim this accurate, eyes-free input characteristic and provide such a large interaction area. Skinput, a technology that appropriates the human body for acoustic transmission, allows the skin to be used as an input surface. In particular, we resolve the location of finger taps on the arm and hand by analyzing mechanical vibrations that propagate through the body. We collect these signals using a novel array of sensors worn as an armband. This approach provides an always available, naturally portable, and onbody finger input system. We assess the capabilities, accuracy and limitations of our technique through a two-part, twenty-participant use study. interface. It uses a different and novel technique: It “listens” to the vibrations in your body. It could help people to take better advantage of the tremendous computing power and various capabilities now available in compact devices that can be easily worn or carried. The diminutive size that makes smart phones, MP3 players and other devices so portable also severely limits the size, utility and functionality of the keypads, touch screens and jog wheels typically used to control them. Thus, we can use our own skin-the body’s largest organ as an input canvas because it is always travels with us and makes the ultimate interactive touch surface. It is a revolutionary input technology which uses the skin as the tracking surface or the unique input device and has the potential to change the way humans interact with electronic gadgets. It is used to control several mobile devices including a mobile phone and a

Introduction
Touch screens may be popular both in science fiction and real life as the symbol of next-gen technology but an innovation called Skinput suggests the true interface of the future might be us. This technology was developed by Chris Harrison, a third year Ph.D. student in Carnegie Mellon University’s HumanComputer Interaction Institute (HCII), along with Desney Tan and Dan Morris of Microsoft Research. A combination of simple bio-acoustic sensors and some sophisticated machine learning makes it possible for people to use their fingers or forearms and potentially any part of their bodies as touch pads to control smart phones or other mobile devices. Skinput turns your own body into a touch screen
