Here are some samples of fine-resolution sampling of eye-movement patterns: In just over 3 minutes we collected ~200K data pts !  Importantly, even w/such a brief  period many interesting search patterns emerge. First, here's an overview of the 3 trial's  data,  timing & video samples of the demo search tasks.
