An eye-tracking camera calculates where the wearer is looking, and transmits it to all the nearby internet-connected devices, such as stereos and TVs, via Wi-Fi. Any devices within the field of view reply with a beep played through the headset. When the wearer hears it, they nod to confirm a desire to connect. Two speakers in the headset then send out an inaudible sound. Mics in the nearby devices use the sound to calculate where the wearer is standing, enabling each device to discern if it is the lucky selectee.
Two people wearing the headsets can also connect. Though iGaze does not address interactions once connected, the idea will be to allow wearers to swap files or contact information with a glance or tap on the headset, for example.
Lan Zhang at Tsinghua University in China presented the work at MobiCom in Maui, Hawaii, this month.
Zhang and colleagues say the device could let wearers interact with the world in various new ways. In museums, for example, the device's head-up display could serve up extra information when a visitor looks at a given exhibit.
