The main thing is the iBreak processing program. You'll need to install the OSCP5 library in processing to develop. The repo also includes a program called FaceOSC in the sketch's data directory, and it launches that program when you start (https://github.com/kylemcdonald/ofxFaceTracker). Should work for windows and mac. Easiest to get started with the windows and mac builds from the releases section
keys:
-
LEFT/RIGHT -- guess which way the grating is going. If it's pointing up and to the right, guess 'right'. up and to the left, guess left
-
UP/DOWN -- change the coarseness of the grating. Helpful if your eyes are particularly strong or weak at these distances.
-
'b' -- toggle blanking the text, so it's just color cues -- sometimes text can be distracting
colors:
-
Yellow: move forwards
-
Red: move backwards
-
Green: guess left/right
