If you’re looking for the future of presentation technology, you only need look as far as CSI Miami and its futuristic rainbow-lit headquarters.

That’s where you’ll find image scanners that can query a database of all the left-handed golf gloves in Florida, and bring up a photo and address of each owner. We’ve previously discussed their image sharpening software that can take a grainy security camera image and enlarge it to full HD.

Then there’s the transparent screens that allow you to flick images around with your hand like playing cards, which you can see at the 2′30″ mark here:

Now, you could say that CSI isn’t realistic program. That’s a fair viewpoint when last week’s TV Guide offered this as the plot of CSI NY:

“After a buzzard flying over Manhattan drops a human eyeball into Stella’s coffee, the race is on to find its owner.”

But as it turns out, we’ll all be getting our greasy hands all over our presentation material sooner than we think. Here’s the just-released Light Touch from Light Blue Optics.

It’s “a laser projector that turns any flat surface into an auto-focused and image-adjusted 10-inch touchscreen with WVGA resolution thanks to its laser- (not LED) based pico projection engine dubbed HLP (holographic laser projection) and infrared touch-sensing system.”

Amazing. Obviously its uses go way beyond the tradition presentation-based projector, like in retail:

Stand by for interesting changes to the way presentations work.

And get ready to see ‘please wash your hands before touching our screen‘ signs in conference centres.
