Having some easy-to-use, easy-to-integrate trackers like the Vive tracker seems highly critical to advancing this medium, in my opinion.
Is Oculus working on its own tracking puck like this?! https://www.vive.com/us/vive-tracker/
Virtual reality is currently only halfway to amazing, in my opinion. Sure it LOOKS real and immersive. But does it FEEL that way (touch wise)? The ability to utilize (hopefully multiple) trackers to match visuals with real world objects seems like it should be an absolute priority in this world.
