Regarding augmented reality, I have been working on it for a while now. There is a LOT to it, not just hardware, btu good hardware is key. I used the Microsoft product (name escapes me) and will be working with the Oculus Rift DK2 on Saturday. My searches for Linux software and drivers that are necessary in order to use the ready-made API show that there is little out there at the moment. If anyone has any info that I should be looking at, please share.
