I don’t believe they’re using Primesense tech, namely because Primesense was acquired by Apple and no longer exists.
There are other depth sensors available from Soft Kinetic, Intel and others out there.
It’s a big software egg to crack, there’s tons of work being done on SLAM research (Simultaneous localization and Mapping) which gives computers the ability to figure out where they are and where they’re going. It’s just a matter of getting the code to play along but there is tons of research in the field and it’s pretty awesome.
It will be fun once we get there. I had done a huge pitch on why depth sensors and SLAM were going to be hugely important in the future but apparently my lack of being a software genius means that telling people it will be cool isn’t as important as building it out yourself. And with all the universities and start ups pushing on it it just meant I get to sit and watch.
