$5 LCD Monitor to Touch Screen
According to Extremetech reported, Ubiquitous Computing Laboratory, University of Washington staff invented a technique, just a five-dollar into the wall sensor can all LCD monitor into a touch screen.
This technique is referred to as uTouch principle is detected close to the LCD display hands caused by EMI (Electromagnetic Interference) to touch. According to reports, the electronic transmission wire in all rooms have unique electromagnetic signal, an EMI sensor plug to the wall outlet, will be able to read the electromagnetic signal in your room, just keep monitoring, able to detect changes in the room of electromagnetic signals. These changes not only be derived from the switch or the closure of the outlet device, but can also be derived from his hands close to the LCD monitor when EMI change room.
Judging from the video provided by the laboratory, this technique is more obvious delay, but it does do a touch screen form, allegedly detection rate has reached 96.4%, although this figure can be done more high, but some of the "click", the "irresolute back" and the like are difficult to detect small movements lead to the detection rate.
