Because augmented reality glasses should probably be for those who actually need them, researches continue developing more economical solutions for suffers of debilitating strokes and spinal-cord injuries, [Engadget reports](http://www.engadget.com/2012/07/13/eye-tracking-research/?ref=killscreen.com). These glasses track eye movement with $35 worth of parts.

> The tracker works with two video console cameras and a pair of eyeglasses that, after calibration, can precisely track the pupils — allowing them to control a cursor or move a paddle. The researchers also figured out how to “click” the eye-mouse by winking, and can even use more precise adjustments to calculate gaze depth — meaning subjects will be able to perform more complex tasks in the future, like guide a motorized wheelchair. While by [no means](http://www.engadget.com/2012/05/24/northeastern-university-students-develop-eye-controlled-robotic-arm-to-feed-patients/?ref=killscreen.com) the [first](http://www.engadget.com/2008/06/11/video-neovisus-gaze-prototype-enables-handsfree-computer-contro/?ref=killscreen.com) eye-tracking [system](http://www.engadget.com/2011/04/15/students-create-affordable-eye-tracking-tablet-for-the-disabled/?ref=killscreen.com) we’ve seen, it’s by far the most economical.
