What a wonderful test. Mr R has alternating strabismus, and a very strong suppression. The Binocular Suppression scene is now designed well enough that it not only demonstrates the suppression switching on very well (by introducing conflict), but allows us to find that breakthrough point where – despite the suppression – Mr R can see both (despite the conflict). The eye misalignment worked well. Mr R couldn’t see any depth in the depth test – which was precisely what I expected at this stage from him. Unfortunately, there was ambiguity in the alternating fusion scene and the eye straightening scene, because it wasn’t clear enough if both eyes were active or not.
I will make a series of improvements which allow us to interactively introduce/remove conflict in these later scenes, and provide visual cues so it is clear without a doubt, what they participant is actually experiencing from their descriptions of what they are perceiving.
