You must have got that email forward that says that your keyboard carries more germs than your backside. The message, apparently, is not that you can scratch your backside and eat with the same hand. The message is that you shouldn’t type on your computer keyboard and then eat without washing your hands. The real implication may be clinical: a new technology that allows surgeons to review CT-scan or x-ray images while operating, without touching the computer keyboard, may actually help prevent wound contamination.
According to the New Scientist, this new touch-me-not technology (likened to that in the movie Minority Report) allows a surgeon to wave his hands in mid-air in front of the computer to flip over to the next pic.
…a screen and gesture-recognition system that allows surgeons to flip back and forth through radiology images, such as MRI and CT scans, by simply groping in mid-air. Their system, called Gestix, comprises a colour video camera above a flat, widescreen monitor placed next to the operating table. The video signal from the camera is fed to a PC, where software trained to detect the colour of the surgeon’s gloves tracks the movements of their hand.
This, they believe, could help stop the spread of the deadly MRSA bug in hospitals.
The catch is that surgeons would have to be taught eight hand movements. Now, isn’t that expecting too much of a surgeon, who is, by popular consensus, the Kanishka (headless/brainless king) of medicine?
