Something to see
Right now, miniature projection systems, often referred to as pocket or pico models, are typically hand-held, free-standing units plugged into laptops. They can be used, for example, to show PowerPoint slides during a business trip.
But projectors now in the prototype stage will be appearing in many new guises. Light Blue Optics, based in Cambridge, England, is already offering sample production models of the Light Touch, a small projector with an infrared camera, infrared beam generator and software to interpret taps and swipes on the image, said Christopher Harris, the chief executive.
