TI's pico-projector assembly promises to place mobile movie magic at your fingertips.
Downloading video onto a mobile phone could take on a whole new meaning with these pint-sized projectors.

Ask people why they don't watch video on their mobile phones and most will cite the small screen size as a major drawback. Texas Instruments hopes to solve the problem by letting mobile users project images from their wireless device onto a screen or a handy wall.

Making good on promises the chipmaker made earlier this year, TI used the CTIA Wireless 2007 show this week in Orlando to publicly demo its "pico-projector" prototype for the first time. A tiny version of its DLP image projection technology, the pico-projector is small enough to fit inside a cell phone. The device builds on TI's existing efforts in mobile projection technology, culminating in the 2006 introduction of DLP-based pocket projectors from Mitsubishi, Samsung, and Toshiba.

"Over the next few years, we envision a large opportunity for the convergence of projection technology and mobile devices, like cell phones," TI's Worldwide Strategic Marketing and Business Development Manager for DLP Front Projection Frank Moizio, said in a prepared statement.

Unlike existing DLP-based pocket projectors, which rely on an LED light source, CNET reports that the pico-projector device incorporates three lasers, along with a DLP chip and a power supply. Housed in a nonfunctioning cell phone for this demonstration, the projector itself measures about 1.5 inches in length. TI officials claim the device provides DVD-quality video, and the projection technology allows an effective screen size that far surpasses even the largest cell phone displays.

A variety of mobile devices could ultimately incorporate cell-sized projectors, including digital cameras and camcorders, as well as portable video players. TI has not announced availability or pricing for the pico-projector.

projection mid air

Obviously nobody responding to my first post has played Xenosaga...

The projection would basically two diff planes extending no more than a foot from the device, one for a screen and one for a virtual keyboard.

And I said no particulate matter or infinite projection. With advances in quantum mechanics I'm sure we will eventually stumble on some neat way to do mid air projection that just looks like a 15" translucent screen floating out a few inches from your hand held device, and another plane with a virtual keyboard projection and touch screen.

I imagine it will have something to do with intersecting some kind of charged beams or waves/fields such that their intersected streams emits a photon out of the stream perpendicular to the intersection, such that you see the source of the light coming from the intersection point. Just steer the beams and you have a raster display emitting photons toward your eye from thin air without the photon having been reflected off any solid matter first. Say there was a way to bind a charge to a photon you could just emit a serial stream of 'charged light' at diff wavelengths for RGB colors and use a magnetic field to steer the stream into a coherent raster display.

I know I'm just making up crazy stuff, but quantum mechanics in and of itself is crazy so I imagine we will come up with something like that some day.

Thanks for the explanation. And the stuff is not crazy...that must be possible eventually. Lets hope for the best and hope they make it soon so that we could get our hands on such a device.
