Holographic Laser Projection

Well if touchscreen technology wasn't enough, holographic laser projction essentially turns any surface into a touchscreen!

This awesome technology is unfortunately largely an industrial display system where is it used to great effect to mitigate issues such as cross contamination or simply in harsh environments where normal interfaces might be inadequate.

You have to wonder though how long it will be until technology like this starts to be integrated into our everyday lives and on a bigger scale, these displays currently are only about 10" across.

No worries though, it's unlikely for this technology to take long considering how affordable normal touchscreens are becoming now, some are even similar in price to standard LCD screens only a few years ago!
