Researchers at Microsoft and the University of Washington have found a way to harness the ambiance electromagnetic radiations produce by human.
What is its purpose?
It can change any wall in the building to an interactive surface from which light switches, thermostats, stereos, televisions, and security systems can be controlled. It also provide new dimension to gaming.
The ambient electromagnetic radiation emitted by home appliances, mobile phones, computers, and the electrical wiring within walls is usually considered noise. But the researchers chose to put it at the core of their new interface. The researchers said that every electromagnetic radiation needs a receiver and human body is a very good antenna for this.
When a person touches a wall surface with wiring at its back then he/she becomes an antenna and which is tuned by radiations generated by the wires producing a separate electrical signal. Thus the electrical signals received and collected can by a device in contact or close to the body (human antenna). When a person touches a spot on the wall behind her couch, the gesture can be recognized, and it could be used, for example, to turn down the volume on the stereo.
