Vibration-compensated mini projectors

June 14, 2007 Miniature projectors embedded in our cell phones, handheld game consoles and other personal electronics appear very likely to play a major role in the future of information display. Projecting a large screen display on a wall appears the most effective way we can currently envisage having a large screen inside a small form factor. One of the problems will of course be that a handheld device projecting a large screen might not lead to a stable, vibration-free and easily readable display. Now German scientists from the Institute for Photonic Microsystems in Dresden have combined a compact laser projector system with inertia and yaw rate sensors to project vibration-compensated images. The sensor system detects the slightest motion and rotates the image to compensate for it, ensuring a steady picture, even in a moving vehicle. The system could be commercially available within two years.
