This tool lets me visualize and clean data from the eyetracker i built for my dissertation. 50,000,000 samples (collected in 50 sessions), with state transition flags synced with time along the x-axis. Green means game has started, red means game has stopped. The scrollbar at the top pages the data for a session so I can easily query/refresh it in chunks (defined by limit). Changing the limit changes the zoom, essentially.

You can toggle lines on/off with the show buttons.

lots of noise in the data due to blinks and/or momentary loss of track -- but this tool lets me quickly isolate the signal through the noise.

Anyway... fun fun...
