      Actually.. their original product plan had the image directly beamed into your eye... virtual retinal display. Rumor has it that Bill Gates suggested they turn it around and point it at a wall instead. Their "Power of one" motto pointed out that there were no problems with dead pixels ( unless of course you lost one color or the "one" pixel ). The nicest part in my opinion is that there is no focus as the image is being transmitted from what would be the focal point ( hence the "virtual image" bit ). I suspect this focus-less projector will allow better "surround" virtual reality systems.. just blast the image onto full-face visor! They must've thought of this.. it's such an obvious use?

        As far as the laser.. I don't think it uses a laser anymore.. the led update was surprisingly richer and made the laser version look like chicken scratches.

        Nice to see they might make some money off of this technology instead of turning into a boring barcode scanning company. Maybe they had some other money makers to shake lately?

    While I'm sure the original price tag will be steep, this product could actually have some pretty sweet applications.

    Imagine a singular device, the size of a cell phone, that could be a wholly working portable computer. You set it down and it projects a screen wherever you need it. Imagine that projector with something like this [thinkgeek.com], and some sort of mouse replacement, and you'd have all your IO needs on the go. Instead of being restricted to tiny screens and keyboards, your portable device could be competition for your main desktop (which seems to be the route that consumer electronics are heading).

    I know I can't wait for the day when I carry around one wallet sized (or smaller) device that is an audio player, a cell phone, and feature complete computer, capable of being used for the same applications my laptop is for, but with far less weight and size. Hopefully with devices like this, I won't have to wait until I'm near dead to enjoy such luxuries.

    Lately I've been giving some thought about how the hard part of multi-touch touch panel [youtube.com] is the projection. Such a screen can be built from a sheet of glass+webcam, but the problem is that projecting an image back onto it requires a rather expensive projector. A $200-$300 laser projector would take this into the realm of 'affordable' technology.

    It could also render the OLED technology of the 'optimus maximus' keyboard obsolete- many people have a second VGA port that they do not use. Using this port to display a key map onto an essentially transparent keyboard would do the same. It could also allow people to choose the decoration to be displayed on the rest of their keyboard.

      I think your power calculations for skywriting are off by several orders of magnitude. That sort of laser is best not used near anything combustible either, not unless you want it to combust that is :)

      A friend of mine who pioneered lasers in pop music (for Genesis in the Peter Gabriel days) once turned down a proposal to implement this because of the limited range of conditions when it would operate and the enormous power levels required, it's a bit of a difference to project something on a wall 5' away from you vs on a semi-transparant medium several hundred meters away. Of course you don't need to take my word for it, or you may have meant your original post in a sarcastic way (but that's hard to tell here sometimes).

      a 50 mW laser will carray a good distance as long as you don't start scanning it, then it quickly becomes useless.

    I own a PK20 pocket projector. It fits in the palm of my hand, does 800x600 native, and uses ultra-bright LEDs with DLP tech to handle the images. It gets 10,000 hours of lamp life but is fairly dim as a result. It is much brighter then the first gen, PK10, but it still gets washed out easily. In a lightly lit room, I can do a 40" image, and in pitch darkness(or almost black), I can project around 60-70" without issue. I'm curious how the brightness of the lasers will be. Will it be able to project a 5' image in a lit room, or will it need the lights fully dimmed? I also wonder what the viewing angle will be, will it be very narrow with a fast drop off to the sides (which would make it less then ideal for portable presentations). Does anyone have any actual specs on the unit?
    • The only thing on the brightness I could find was this snippet:

      "In the demo at Digital Experience, PicoP cast a vibrant image of Disney's Finding Nemo on a common piece of 8.5-by-11-inch white paper. The image was clear, but the amount of light in the large conference hall did not offer an optimal viewing environment."

      • Why yes it does. Viewing angle should be similar to viewing a painted wall - the perceived narrowing of the image would be a problem long before not seeing the light would be. Have a translucent screen and you'd be able to have rear projection.

        As for power - it doesn't sound bad. If it's anything like many other conventions I've been to - the ambient light level could be described as 'as bright or brighter than outdoors at noon'. If it's still capable of projecting a 'vibrant' image on an 8.5x11" piece

        The scanning electron beam is exciting phosphors that continue to glow long after the beam has passed by.

        With a laser on a standard surface, it has to be bright enough to overwhelm the receptors in your eye so your eye still thinks it sees it until the beam gets back to that spot again.

        Not even remotely similar.

      Considering your eyes work at around 24 frames per second, I'd say it was acceptable. (TV and Computer monitors run at 60fps as well.)

With a scanning beam, the energy being reflected or diffracted at any point in space is too small to worry about, except very close to the projector exit window, which you aren't looking at anyway.
