Beijing: Researchers have built a wearable headset that tracks your gaze and connects you to the devices you look at.
The gadget, called iGaze, contains an eye-tracking camera that calculates where the wearer is looking, and transmits it to all the nearby internet-connected devices, such as stereos and TVs, via Wi-Fi.
The 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 has been selected, 'New Scientist' reported.
Two people wearing the headsets can also connect. The idea will be to allow wearers to swap files or contact information with a glance or tap on the headset.
The device was developed by Lan Zhang at Tsinghua University in China who said it could let wearers interact with the world in various ways.
In museums, for example, the device's head-up display could serve up extra information when a visitor looks at a given exhibit.
