Doctors Test Newly Invented Gestural Interface During Brain Surgery

Source: Dailytech

The new system, known as Gestix, eliminates the need for complex and largely ineffective sterilization procedures on today’s OR touch screens.  When surgeons first start with the system, they train it and learn to use it by learning to move their hand in one of eight directions away from a neutral area, fast.  This movement scrolls the image.  They also learn to zoom in and out by rotating their hand clockwise or counterclockwise.  To avoid misleading signals, when the doctor is done, they drop their hand which triggers a sleep mode.

The hand motions are captured using a Canon VC-C4 camera and they are processed by an Intel Pentium processor and a Matrox Standard II Video Capture device.  The system was tested to much success at the Washington Hospital Center in Washington, D.C during two “in vivo” neurosurgical brain biopsies.  This may be the first time such a system was used with an “in vivo” procedure, according to the researchers.
