How can I make this question more measurable, without it becoming more complicated? https://gamedev.stackexchange.com/questions/79506/oculus-rift-and-super-resolution
For example a good test could be a character fixed in position in a simple game-world, at a given low resolution, with for simplicity as it might mane a big difference no full screen AA, looking around with mouse-look and asked to describe an object pointed at in the world that is much smaller at the distance it is away from the player than a pixel (block of pixels as part if simulating the low resolution) of the conventional screen.
Then repeating the experiment with the rift and head-look.
However ideally there would be a sample of at least a few people, perhaps different sorts of people as well, for practicality I wanted to use just 1 person.
