Tobii Technologies revealed its second-generation smart glasses, Tobii Glasses 2, that can track what the wearer sees.
The glasses were designed to study how people interact in certain environments and what they look at in a shop, restaurant, or other real-world situation, according to PC Magazine. Tobii introduced its first prototype, the Tobii Glasses Eye Tracker, four years ago.
Research professionals can use the glasses to observe scenarios such as a shoppers looking at items in a grocery store, or a wearer's sudden response to a TV advertisement.
The device can also be used to study social interactions, such as what part of a person's face people look at in different social situations, Mashable reported.
"What you're actually watching is the overlay of the gaze of the video," said Barbara Barclay, general manager of Tobii North America. "The glasses themselves have no obstruction on the peripheral, so [they] can eye-track a wide area."
Tobii Glasses 2 comes with several upgrades, such as the eyes being tracked by two cameras. Wearers can adjust the glasses just a little, to better track other people's gazes.
Tom Englund, president of Tobii, the glasses being easy to use, along with holding "endless possibilities," makes it an "amazing product," according to PC Magazine.
"We've listened to our users, we've observed them in the field," said Heather Kay, expert in user experience. "We've seen what works, what didn't work so well with our previous pair of glasses."
Tobii Glasses 2 features the wireless Live View function, which lets researchers see exactly what wearers are looking at. It also includes a wide-angle HD scene camera and thin side pieces for peripheral viewing.
The basic Live View version of the glasses is available for $14,900, Mashable reported, while the Premium Analytics package is available for $29,900.
The glasses weigh 45 grams (0.10 pounds) and include SD card storage, 2.4 GHz and 5 GHz band Wi-Fi, and 120 minutes of battery in recording mode, PC Magazine reported.
"With Glasses 1, we revolutionized the eye-tracking market," Rasmus Petersson, product manager at Tobii said. "With Glasses 2, we will do it again."
