Talking to the Wall

Microsoft and the University of Washington researchers have learned a new way to use electromagnetic radiation and use it as a computer interface for creating walls touch-sensitive. Electromagnetic radiation is all around the air. This new type of techonology could allow people to control light switches, thermostats, security systems and TV's from anywhere in the house. This works by someone touching a wall with electrical wiring behind it and then he/she become the antenna that creates background radiation depending on the position of their body. After this occurs the gesture could be taken as a command to turn up the volume or something similar to that. Researchers have only discovered that only the body can be used to turn electromagnetic radiation into a signal for gesture-based interface.
