Revolutionary Pen-Size Computer Uses Bluetooth Technology

A revolutionary new miniature computer is being worked on in Japan that comes in the shape of a pen that you can slip in to your pocket. It projects a monitor and keyboard on any flat surface that you can begin using like any regular PC computer. With its Bluetooth technology, it recognizes your key-presses and inputs as per usual. See the photos below. I’m trying to find out more about it and when it is expected to be available to the masses. Stay tuned!

    This has been going the rounds for a long time and is debunked on Snopes:

  4. Any idea about prices, even a guess?

  5. Andres

    I always lose my pens…

  6. Super Cool… great for travel. Cant be used on a bus, though…

  7. This is actually a 3-year-old concept that came out of NEC’s design lab, similar to how concept cars are created by auto manufacturers.

  8. Thanks TechSoEasy and Debunker for shedding some more light on the origins of this product. It would be interesting to know if this concept has moved any further since introduced by NEC. Everything that it hopes to do seems, to my unqualified eye, quite feasible today. Either way, it’s a great concept!

  9. Well, everything about it may be possible… except power. For it to actually project a viewable image as well as provide reasonable processing power, there isn’t a battery that currently exists which is small enough to allow the thing to operate for more than a couple of minutes at best.

    Batteries definitely are getting smaller, as are processors and memory, but we’re still not going to see something this small for some time yet. For now, this is about the smallest you’ll find:

  10. Niiccce, how much tbh?

  12. Hi Kritika, this is a concept by NEC’s design labs. You can read about it here:

  13. WOW! what an incredible invention, the only problem i can think of with these things getting smaller all the time is that it also makes them much easier to lose or be stolen.

  14. Glenn G. Walsh

    Clarification: Snopes calls “partially true”, not de-bunked. No existing prototype as of 2005. The Snopes is worth reading.
    My kids will have one.

  17. Sanu

  29. rache

    pls send me more info about this!

  30. Trey

    I don’t see how the keyboard would work. Your fingers are going to be getting in the way of the projection, and…how can it tell when you’re “pressing down” or if your hand is just passing thru the laser. The rest of it seems like a good idea, but I think the keyboard part of it needs to be re-evaluated. I really don’t see how it would work.

  31. Rawan Alwan

    Plzz im really exited about that… And i have a seminar this week..soo plz could u send me the full information about that plz..cause i want to present it…

  32. rawan alwan

Thank You… guys superb job… but i just thinking It’s through bluetooth… is there any security risk involve?

  40. Zahid Hussain

    Any idea how much will it cost? besides i think Trey’s (April 10, 2008 at 12:44 p) comments are quite interesting and i would really like to know the answer to it. Some people have also raised questions about accessories i.e. usb and mouse, one can also ask about headphone/speaker or microphone etc.
