Projector technology is getting innovative, smaller and more portable these days, and this is something that everybody must be thankful for. Instead of being restricted to small displays when watching movies or videos on a mobile phone, technology users can now look forward to projecting movies and presentations on a 50-inch display to any surface, which is made possible by the latest mini projector from Japanese company, Funai Electric.
But aside from projecting images, this innovative mini projector can also recognise finger movements on the projected display. This means that you can scroll and control images, or even double-tap them to stop or start a video. This touch-sensitive feature can significantly add functionality to presentations.
The new mini projector, which was developed by Funai in partnership with Nippon Signal Co Ltd, was designed by combining a projector with a scanner and light sensor, two mirrors and a micro-electro-mechanical system or MEMS. It works by scanning the intensity of light in the projection screen. Moving a finger on the projected image will cut off part of the light, changing its intensity. This will be detected by the MEMS mirror, which keeps rapidly scanning the laser light. With this capability, it is possible to project and manipulate images on any surface, including refrigerators, ovens, walls, backs of seats, etc.
Meanwhile, though the technology is still in its prototype stages, Funai is set to introduce the touch sensitive mini projector on the commercial market early in 2010. So, just wait for this second generation projector to make it to the shelves of electronics stores near you.
