To change the Dot size and the distance edit the Button and Canvas Prefabs.
Note: You will have to also change the dot size in the Sample.cs file.

See the utils folder for information on running the backend server and the Experimenter console interface.

Some notes for whatever student is working on this now.
First, know that this codebase was written in about a month, mostly between the hours of 12am and 6am due to a severe time crunch, please chalk any weirdness or dragons you may find up to that. Trust me there are less than the old one.

Collision:
As you may or may not have noticed there are two different collision systems in this codebase for clicking on circles. This may seem a bit overkill. This is because the way Google Cardboard and Oculus handle collision is entirely different. If you are adding a different device to this study/code base. I would highly recommend downloading whatever sample program the SDK for your device gives you and just looking at how it is handling collision/input. That should give you enough ammunition to add your own scenes in the style of the Experiment and Home scenes I have here.


Future Plans

Create (web?) UI for the experimenter so they don't have to change the code  
Capture the cursor movement at 100 milliseconds
