For many users, interacting with computers can be highly frustrating. Keyboards and mice work reasonably well for text and two-dimensional graphics; but wouldn’t it be great if you could talk to your computer, or get action by a wave of a hand? Or have it recognize what you have in your hand, and give you a range of related solutions? This may sound like science-fiction; but given the way technology has changed over the years, you might just see it soon. Microsoft debuted an important stepping stone recently, with the launch of Microsoft Surface.
Microsoft Surface basically has a PC running Windows Vista built into a table, with a touch screen surface. A number of cameras are placed just below the screen – these can identify objects and movements, and use those as inputs to the PC in addition to touch.
