London, June 17 : Researchers at Ben-Gurion University of the Negev (BGU) in Israel have developed a new hand gesture recognition system like the one in the futuristic Tom Cruise movie 'Minority Report' that may help keep hospital-acquired infections like MRSA, which can easily be spread via a keyboard or mouse, at bay.
The new system, called Gestix, enables doctors to manipulate digital images during medical procedures by motioning instead of touching a screen, keyboard or mouse, reports New Scientist.
Juan Wachs and colleagues at the university describe the new technology that comprises of 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.
Gestix simply requires the surgeon to learn eight gestures, including swishing the hand right or left to go back or forth through a preloaded image sequence, or clockwise and counterclockwise to zoom in and out.
In tests of the sterile browsing system during brain surgery, the researchers said that the system did what it was asked to do 96 per cent of the time.
