- ricksplat 10y agoI remember reading, in a computer magazine about 15 years ago about a technology, or else an area of research that claimed to do just this. To infer what is being typed on-screen from subtle variations in radiation emitted from the monitors. Apparently some degree of success was possible even outside a building. It probably related more to the CRTs of the day, and the less noisy UIs.
