One of the exiting fields of embedded computing is 3D vision. The Microsoft's Kinect is certainly the premier consumer product in this category. However, if things go according to Intel's CEO Krzanich Kinect will soon get company. At his CES 2014 presentation he showed off RealSense scanning and gesture control technologies and announced the roll-out of this technology during 2014 with SDK becoming available soon.
Intel is not alone looking at this space. TI is also active in 3D Vision. However, their focus is more on Automotive rather than consumer devices. For those interested to look behind the scene of 3D technology, there is a video interview by Jeff Bier, founder of the Embedded Vision Alliance, that presents some live 3D feeds and explanations by Goksel Dedeoglu, Manager of Embedded Vision R&D at Texas Instruments.
Combining 3D Vision with Infra-Red (IR) imaging technology as showcased in the video below and it is easy to imagine what exiting opportunities are out there.
I agree that some of these technologies are out of reach for a typical DIY Maker. However, as in the past these technologies will come down in their price points and get more accessible to the masses quickly. One 3D Photo/Movie example can be found in Make Magazin. So it is never too early to start imagine what to do with it.
