"What are you looking at?" Said the wrong way, those can be fighting words. But in fields as diverse as psychological research and user experience testing, knowing what people are looking at in real-time can be invaluable. Eye-tracking software does this, but generally at a cost that keeps it out of the hands of the home gamer.

Or it used to. With hacked $20 webcams, this open source eye tracker will let you watch how someone is processing what they see. But [John Evans]' Hackaday Prize entry is more than that. Most of the detail is in the video below, a good chunk of which [John] uses to extol the virtues of the camera he uses for his eye tracker, a Logitech C270. And rightly so — the cheap and easily sourced camera has remarkable macro capabilities right out of the box, a key feature for a camera that's going to be trained on an eyeball a few millimeters away.

    As expected from geeks, the following is carefully hidden in the code:
    IF (gaze_lock == "boobs") PRINT "Mesmerized by her eyes. Peering at her soul."

    After watching the video and TFA I get that this is attaching a webcam to goggles to detect point of focus. Only a matter of time before it is figured out to track your pupils from a camera pointing at your face and figure out exactly what you're looking at.

    I know a doctor who built one of these almost 13 years ago. He used it to track eye movement in the dark using an infrared webcam that he picked up in Hong Kong. He used it to evaluate damage to the vestibular system in patients who'd had strokes.
