Eye Tracking is the Holy Grail of Advertising

Avi Bar-Zeev, who works on AR/VR/MR, says that eye tracking is the holy grail of advertising (And he’s all for it). While I don’t disagree with that point, I do wonder how prevalent it will become. For example, when Face ID first came out, there was a fear that it could be exploited for eye tracking ads. But that isn’t possible because Apple locks down its technology. I expect the same for Apple Glasses.
Bundled into VR headsets or AR glasses, eye-tracking will, in the near-future, enable companies to collect your intimate and unconscious responses to real-world cues and those they design. Those insights can be used entirely for your benefit. But they will also be seen as priceless inputs for ad-driven businesses, which will learn, model, predict and manipulate your behavior far beyond anything we’ve seen to date.
