The Skinput works with multiple sensors to locate areas where there are taps.
So far it is the presentation of the prototype of this technology which have been conducted by researchers from Carnegie Mellon University and Microsoft.
The prototype can detect different types of vibrations produced by the body to be touched with the fingertips. The vibrations are different depending on the area of the body where they occur, by the shape and number of bones, tendons and muscles of the specific area.
Its accuracy is very good, exceeding 90 percent in this register when using the fingertips to operate it, said Chris Harrison, the Institute of Human-Computer Interaction at Carnegie Mellon and a member of the research team, in comments reported by the news network MSNBC.
For the device to operate it is necessary that the user place a sort of cuff on the forearm. This device has a system that receives and decodes the vibrations and then transmit that data to other instruments, via Bluetooth.
This bracelet is a very rustic prototype, as Harrison said the station MSNBC. The next generation should be significantly smaller and easier to use, including placing on the wrist and not the entire forearm, he said.
In daily use, this device could replace keyboards and computer mice. In this way, users could play, make calls and change songs, just touching her arm.
The device will be officially presented at a conference in Atlanta in April this year. Its creators hope that may have future commercial potential.
