Lecture 21: Virtual Reality (105)

It's really interesting how calibrating the VR headset is similar to motion tracking they use in movies with individual light points. It was first used in the original Avatar movie and the technology has evolved to VR to see where the human movements translate in real-time and the efficiency and translation have dramatically increased which is pretty amazing.

I am curious how the implementation of tracking will evolve over time. I feel like there is a move towards tracking systems being requiring less setup over time. I am curious if the implementation with infra sensors around the headset or lighthouses is going to be the way the headset technology moves going forward.

Due to the set up required to use and maintain Lighthouse tracking, I can't imagine that this is the future for consumer VR. The most important feature of Lighthouse tracking that inside-out tracking solutions can't fix is the ability to track objects outside the range of cameras, this can be used to better track controllers, or even additional tracking points--like leg, ankle, and elbows using separate tracking devices.

This reminds me of the Kinect with xbox 360, which used a vide camera and depth sensor to identify where a person is standing, as well as where the controller is.

I've read that the "Lighthouse" tracking system is particularly useful in large-scale VR experiences, for example in arcade or theme parks, because it allows multiple VR equipments to be used in the same space. I believe this is because the light transmitter emits infrared light in a sweeping motion.
