On tonight Silent Witness, one of the pathologists used his hand to drag photos from a folder to open them on a wall sized screen. He also restored a crossed off name. Does this technology really exist?
Didn't see it, so I may be off-base (!) but most schools have "interactive whiteboards" many of which can be controlled by using one's hand as a mouse. You can definitely get touch-controlled flatscreen motiors too. Whether a pathology department is likely to have such funding is another question...
I watch C.S.I. a lot, and although the touch screen technology, combined with a video wall is a real technlogy, some of their reconstructive stuff, like signatures or photo enhancing is a bit too CGI ...
