Researchers Discover Keyboard Signals Pose [news.bbc.co.uk]Security Threat

Computer criminals could soon be eavesdropping on what you type by analysing the electromagnetic signals produced by every key press.

By analysing the signals produced by keystrokes, Swiss researchers have reproduced what a target typed.

The security researchers have developed four attacks that work on a wide variety of computer keyboards.

The results led the researchers to declare keyboards were "not safe to transmit sensitive information".

A similar phenomenon was revealed in the book by Neal Stephenson, Cryptonomicon. In the book, the characters that were output to a screen were detected.

In reality, it would seem that nearly any input or output device could be compromised. If it's electronic, it is producing a field that will change state.
