““Several of her students were engrossed in their work, but when she asked one of them, a PhD student named David Merrill, to give me a quick demo of his project, he readily agreed. Merrill walked us over to a three-foot-wide mockup of a supermarket shelf stocked with cartons of butter, Egg Beaters, and cereal, and he happily slipped on a Bluetooth-enabled ring he had been tinkering with when we interrupted him. He pointed directly at a box of cereal, and a light on the shelf directly below it glowed red. This meant, he told us, that the food didn’t fit the nutritional profile that he had programmed into the device. Perhaps it contained nuts or not enough fiber. He told me that there were a lot of “really cool technologies” making this happen—an infrared transmitter/receiver mounted on the ring, a transponder on the shelf with which it communicated, and a Bluetooth connection to a smart phone that could access the wearer’s profile in real time, to name a few. It was easy to see how this “augmented reality interface,” as Merrill called it, could change the experience of in-store shopping in truly a profound way. But what really impressed me during this visit was the close working relationship he clearly enjoyed with Maes. He called her “Pattie,” and my impression was that they engaged in give-and-take like true collaborators and colleagues.””
