This post summarizes my learning experience with VR headsets as of July 20, 2020.

I’ve been out of the loop with VR development and headsets. On July 8 2020, I watched this video on the HP Reverb G2:

Prior to July 8, I have never heard of this headset or of this man’s YouTube channel. But I’m glad I came across this!

Made me realize that there’s a lot of hardware and other concepts that go into a VR headset. Here are my key takeaways:

1. Inside-Out vs. Outside-In tracking

I knew that the difference between say, an Oculus Quest and an HTC Vive, was that one has external cameras/sensor while the other one doesn’t.

After reading this article, I have expanded my VR vocabulary! So for example, an Oculus Quest uses Inside-Out tracking while an HTC Vive uses Outside-In tracking!

2. “IPD stands for interpupillary distance”

Hooray for learning new words! This heading is a direct quote from this website.

3. Comparing VR headsets

I’m not sure how up to date this Wiki page is, but I like how it gives a technical overview on various headsets.

4. OLED vs LCD

I’m still trying to understand the advantages and disadvantages between the different displays for a VR headset.

In one article I read, Valve and Microsoft seem to favor LCD. But with that said, this article is from 2017 and I don’t know if LCD will continue to be the favored display.

I’ll have to refer back to point #3 on this list to learn more about the different displays among the various headsets!


I have a lot more to learn about VR hardware. This is fascinating stuff!
