This is an exciting development. The advent of small devices to obtain 3D image information (especially if imaging can be done with invisible IR as "clogic" suggests) could enable many new applications for context awareness and gaming. Picoprojectors could also enable large displays for cell phones and computers without the need for bulky screens. I'm waiting for the day that I can work on my laptop computer with a large (picoprojector) projection screen rather than needing to dock into my dual screen system.
Imagine all the possible applications for this new technology!!!
We are facing a way to read from 3-dimensional objects and not only a static object but a moving one.
And this can become the start of “read my lips” app, sign language interpretation and other apps which I can't think of at this moment! Who knows what else will the MEMS enable as this technology is at it's diapers we might say.
The overhead on the processors might be an issue though if the algorithms aren't tuned for reduced MIPS, but that of course opens the demand for new hardware coded devices.
In the near future we won't need a mouse to control the pointer in the computer and perhaps the PC interface will be as in the Minority Report movie... cool!
