This ad for Amnesty International is the first-ever poster to employ eye-tracking technology. The poster is an anti-abuse ad that depicts a smiling couple - at least when you're looking at it. When you look away, it shows a man hitting a woman.
According to blog Gizmodo, this is how the technology works -
“The billboard works by scanning its proximity with an eye-tracking camera, which triggers an image switch on the display panel when it senses someone looking at it. The change only occurs after a brief delay, so that observers understand what's going on, and get the message.”
Pretty innovative stuff -- and the medium is a perfect fit.
Now I just want smellavision to become reality.
