Denmark’s The Eye Tribe is not an indigenous group that worships the ocular organ, but a startup that works in machine vision, specifically developing eye tracking tech for use in consumer electronics. In service of its goal of delivering gaze controlled games and software applications to users on a broad scale, The Eye Tribe today unveiled a $99 USB 3.0 hardware accessory for Windows devices, which provides eye tracking capabilities to any tablet, laptop or PC running Microsoft’s desktop OS.
