Light Touch turns any surface into a color touchscreen display

Ok, this cool but the real use for one these.  Well, let’s think about it.  Physical keyboards weardown and are easily vandalized.  They get very dirty. When was the last time you sanitized your keyboard?  Even if you do it daily, do you get under the keys too. What about kiosk keyboards?  When do they get cleaned? …and so on…

Have any applications come to light? I have a few.

Here’s one.  What about in “dirty” work environments?  Dirty as in: 1) harsh climates – e.g. temp, humidity; 2) airborne contaminates – e.g., dusty; or 3) biohazard ; etc…  Just project the keyboard on a hardy surface and wipe that clean with some bleach and you’re done.  There’s so much more…

Light Blue Optics’ Light Touch turns any surface into a color touchscreen display (video hands-on)

Ever heard of a small company called Light Blue Optics? Probably not. But it’s companies like LBO that make events like CES truly worthwhile. Tucked away in a small suite overshadowed by the million dollar spreads owned by industry giants like Samsung and Sony is a tiny startup looking to attract the attention of OEMs with its full-color holographic laser projection technology. The Windows CE-powered Light Touch represents the company’s very first effort to create an interactive projector that allows users to interact with the displayed image as they would a modern touchscreen display. Despite our skepticism, we came away suitably surprised — impressed even. Granted, our hands-on was performed in a lowly-lit room on par with the lighting you might find in a fine restaurant. Still, the 15 lumens were effective at lighting videos and the touch sensitivity was far more accurate than we expected — so good that we were quickly typing out phrases on the QWERTY with few mistakes (admittedly taking a reasonable amount of care to strike the right “key”). The projector only supports single-touch at the moment though multi-touch is just a software tweak away. See the video after the break and prepare to be suitably amazed at watching a laser projector create a touchscreen display.
