I ran a few people through the baseline pilot last week; data’s not ready yet, but here are some thoughts on the general process, and participant feedback:

Things are running two to three times longer than expected; automating measurement may cut this in half.

There may be a kind of fatigue effect from being in the virtual environment too long, losing what sounded like a sort of calibration between proprioceptive and spatial senses; only one of four participants reported this, so there may also be different internal models at work between them.

Participants report being aware that only two distances were being presented; it was suggested we might test continuous distances along our range of interest.
