Graphics Tablet A  graphics tablet  or  digitizer  is a computer input device that enables a user to hand-draw images, animations and graphics, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper which is taped or otherwise secured to the surface. Capturing data in this way, by tracing or entering the corners of linear poly-lines or shapes, is called digitizing. The device consists of a flat surface upon which the user may "draw" or trace an image using an attached  stylus , a pen-like drawing apparatus. The image is displayed on the computer monitor, although some graphics tablets also have a screen. Some tablets are intended as a replacement for the mouse as the primary pointing and navigation device for desktop computers.

I was in the passenger seat as Krishnan wheeled around a corner and hit the gas. A moment later a light flashed on the dashboard, there was a beeping sound, and our seats started buzzing furiously. Krishnan slammed on the brakes, and we lurched to a stop just as another car whizzed past from the left, its approach having been obscured by a large hedge. “You can see I was completely blinded,” he said calmly. The technology that warned of the impending collision will start appearing in cars in just a couple of years. Called car-to-car or vehicle-to-vehicle communication, it lets cars broadcast their position, speed, steering-wheel position, brake stat
