Despite the rise of touch screens in electronic devices, there are still uncomfortable or too small considerations to handle with the same dexterity as conventional interfaces. To solve this problem of size, a research team consisting of scientists from Carnegie Mellon University and the Microsoft laboratory in Redmond has devised a system that allows you to use your own body to control mobile phones, sound players, or even computers , according to a statement published by Microsoft and collected by New Scientist.

US researchers have designed a system that allows you to use your own skin on your hands and forearms to control mobile phones, audio devices and computers. The prototype works by detecting the ultrasounds of different frequencies that occur when different parts of the skin are pressed.

The idea is based on acoustic sensors that pick up very low frequency sounds produced when making contacts with the skin, and according to some patterns a correspondence is made with an action in the system. To complete the set, the interface with which we will work is projected onto the skin.

Skinput puede enviar la información recibida, sin cables, a otros dispositivos como un teléfono móvil o un PC gracias a su conectividad Bluetooth. Según nos informan los desarrolladores el sistema puede detectar interacciones con 5 partes distintas del brazo con un 95% de acierto, y funciona incluso cuando el sujeto está en movimiento.
