Wearable LCD Display 186

Posted by michael from the heads-up dept.
fenimor writes "PhysOrg reports, that Mitsubishi is going to introduce next year a headset with a small liquid-crystal display screen which is positioned in front, slightly below eye level so as not to obstruct normal vision. Designed for users who need to perform multiple tasks simultaneously, this tiny wearable heads-up display is expected to cost only US $400."

      It would be good for road driving if you could have a map of where you were going displayed below your view of the windscreen.
      Especially if it could tell you which lane you should be in, and which direction you should go, in order to make the correct intersection change on the freeway. Or maybe it could be used for driving in foggy/rainy conditions.

      How many accidents have been caused by someone trying to read a map, while trying to drive at the same time?

          It would make more sense, but a projection system for a windscreen is far more expensive than a headset mounted LCD display. For a windscreen, you need a bright light source, reflective mirror and a large projector, all in order to generate a image large enough to cover the visual field, which can just as easily be generated by a small LCD display close to the eye.

      Doing the 2 tasks concurrently requires t1 + t2 + cxt.

        Another advantage of an RSD is that it is a spinoff of a device to scan the retina, and adding one more beam-splitter and a photodiode on the laser side of the scanner lets the display do this, too.

        That leads to two extra functions:

        1) The retina print can be used for a "password". (Fewer worries about somebody who steals your wearable getting at your data or using your comm account to make 20-hour calls to 900 services in Malagua or spam the whole internet.)

        2) The display can measure where you're looking - and use that (with suitable algorithms to keep the cursor from being obtrusive) as your pointing device. (Look-and-click means one less device in your hand, i.e. a chord keyboard with mouse button chords in its vocabulary. And it ought to be a bunch faster than mousing.)

    What resolution can these things display? The linked article and video doesn't mention anything. MicroOptical [microopticalcorp.com] already makes things like these. They have a number of different versions [microopticalcorp.com] and can display at VGA (640x480) resolution. They have binocular [microopticalcorp.com] versions, and there's even one [microopticalcorp.com] in which the display is a reflective portion of a transparent eyeglass lens that looks like a bifocal. Why wait until next year for this one from Mitsubishi when MicroOptical already has a whole range of different kinds now?
  • This isn't a "heads-up display" (HUD).
    It's a "head-mounted display" (HMD).
