Oculus Calibration

Getting a bit sick and other personal events, coupled with a substantial homework, meant not much progress on the pilot this week. I did start sifting through the VR proceedings, mostly skimming for anything of interest. I …

Sidetracked a bit by classwork and feature creep, the coding continues. The features are for more efficient debugging and development flow — things I was hoping to put off until after the pilot, but that …

Still building the base code. Rediscovering the joys of const correctness and circular inheritance. Should be done this week. Also found something in the below papers I should look into later — they suggest that people …

I’m in the middle of building some c++ openGL foundational stuff. I expect it to be done in a week, week-and-a-half. The goal is to have something lightweight for quick prototyping, without disrupting the lab’s …

I found the bug. I’ll do a proper writeup in this space soon, but the gist is they do latency testing as part of the timewarp headpose prediction; they do this by drawing a rectangle …

Built the bulk of a simple wrapper for the Oculus lib. Should make debugging faster. Needs a review pass for general organization / naming if I want to share with others, and I’ve still some …

It seems to be well understood that accommodation declines with age, but I’d like a strong reference to cite, and a little better understanding of the how and why. Still don’t have a ref I …

A participant views a circle placed on a table in front of them, and is asked to describe what they see.  Their answer lies somewhere between what geometry tells us the retinal image should be (or, …

Accomplishments This semester, I’ve explored issues relevant to stereoscopic rendering in general, and the Oculus Rift in particular.  I’ve also explored the current state of software packages that offer rendering to the Rift.  We’re on …
