The most remarkable part of this environment can’t be shown with a still image. As you approach the back shelves, discreet cameras track your eyes’ movements. When you look at a shelf, sophisticated software detects the object of your gaze and lights glow around that shelf. When your eyes drift left, the computer tracking your pupils dims the light on the last object of your attention and illuminates the next. The computer reacts so quickly to your moving pupils that light seems to follow your eyes in real time.
This system can track the eyes of only two people at a time, and the viewer has to be within a certain range for the system to work.
Tobii is working on this. It’s called passive eye-tracking, and it should be ready in 12 months or less.
