Considering Cheaper Pico-Projectors As Standard Equipment On Cell Phones 146

Posted by timothy from the beam-it-at-the-wall dept.
An anonymous reader writes "Will pico-projectors become standard equipment on mobile phones, the same way that digital cameras have become? The jury is still out on user acceptance — after all, only four mobile phones use pico-projectors today — but if they get small and cheap enough, mobile phone makers are going to install them. There are four vendors today — Microvision, National Semiconductor, 3M and Texas Instruments — but only TI has design wins in cell phones already on the market. And at the recent Mobile World Congress, TI showed a smaller digital light processor (DLP) chip that fits inside even the slimmest mobile phones, and which it claims is cheap enough to become standard equipment. A lot of us never use the camera in our phones now — would you use a pico-projector if it was built into your phone?"

A modern LED can provide as much light as the bulb in my projector (which is usable for most of the day, but not with direct sunlight on the screen). The LED would draw 11-20W, depending on the technology used. That's about the amount that a laptop display uses, so it's not impossible but it's a bit much for something the size of a mobile phone.

  • Could be in the middle of the path to get to SixthSense [ted.com] technology to phones. But if it even works to get a bigger screen for the phone (i.e. to see a movie in a wall instead of in a tiny phone screen) could have some sense.
  • I think the notion of a built in project is great. However I really cannot understand why they're designing them so bloody thick just to accommodate the projector chip. The ones that the TI guy was showing off were fairly wide but actually quite thin. I think it would make far more sense to simply have the projector chip lay flat just like the camera chip but have the ability to "pop-up" and be adjustable to different angles. That way not only do you enable the phone to remain nice and thin, but you als

      Complete WAG -- maybe the DLP chips need a bright light source behind them?

  • I'm waiting for these SVGA resolution, focus free [syndiant.com] projectors before I jump on the bandwagon.

  • Obviously the killer app for mobile handset projectors is direct projection onto the user's retina, perhaps aided by adaptive calibration using cams and ultrasound to detect ocular motions/sacaddes,slow pursuits and to respond to them both in real time and in anticipation. I expect eventually this will be on a bunch of phones for 2-3 years but many will disregard it as pointless and most will ignore it or simply be utterly oblivious to it until Apple releases a phone using this technology and dropping a mas

  • There too useful not to. From showing a group something on the device, to needing a bigger view of a map, to new types of games, and boardroom meetings.

    I even imagine using it to share information by having on device see whats on the other is projecting creating a new type of AR.
