ABSTRACT
Skinput is a technology that appropriates the human body for acoustic transmission, allowingthe skin to be used as an input surface. In particular, the location of finger taps on the arm andhand is resolved by analyzing mechanical vibrations that propagate through the body. Thesesignals are collected using a novel array of sensors worn as an armband. This approachprovides an always available, naturally portable, and on-body finger input system. Thecapabilities, accuracy and limitations of this technique are assessed through a two-part, twenty-participant user study.What is Skinput?
Skinput is a new skin-based interface that allows users to use their own arms and hands as touchscreens by sensing different ultra low-frequency sounds that are generated when knocking various parts of skin.
The feature of providing input using this projection is a boost. Simply, Skinput is the latest technology of providing input using the projection on the human body. The technology was originated from the researches of Chris Harrison, Desney Tan, and Dan Morris at Microsoft Research’s Computational User Experience Group. The term Skinput is the combination of the words skin and input that implies the functionality of the technology –input thru skin.
How Does Skinput Technology Work?
In this technology, a menu, keyboard or any other graphics are spread on to the user’s forearm and palm from a projector that is embedded in an armband. This band has an acoustic detector, which decides the part of the display that has to be activated by the touch.The scientists explain that the changes in bone density, mass, and size along with the filtering effects from joints and soft tissues mean various skin spots are acoustically discrete. The software goes with sound frequencies to particular skin spots, permitting the system to decide the skin button pressed by the user. Following this, the prototype system makes use of a wireless technology like Bluetooth to send the commands to the device that is controlled (ex: iPod, phone or computer).
Skinput thus functions by listening to vibrations of the hum body. And, this is indeed a groundbreaking concept in itself. It’s definitely the most unique form of touch sensitive so far
Applications of Skinput:
- Audio player strapped to the arm that can be controlled using finger tips.
- Computing devices to computer without the need of some external application.
- Portable computing devices with a pico projector.
