TaeKwonDood writes to tell us that another step towards Star Trek's Holodeck technology has been taken with the advent of HoloVizio 3D. Allowing users to see and manipulate objects in 3D without the assistance of goggles, this distributed system shows a lot of promise. "The HoloVizio is a 3-D screen that will allow designers to visualize true 3-D models of cars, engines or components. Better yet, gesture recognition means that observers can manipulate the models by waving their hands in front of the screen. The function offers enormous scope for collaboration across the globe."
