Athletes of every age receive a lot of blows to the head. After a few years of this and a lot of concussions, symptoms similar to Alzheimer’s can appear. For his Hackaday Prize entry, [Mihir] wanted to build a simple device that could be given to high school coaches that would diagnose concussions. He came up with HeadsUp, a device so simple even a high school gym teacher could use it.
The origins of HeadsUp began as an augmented reality device, but after realizing that was a difficult project, pivoted to something a bit easier and even more useful. HeadsUp tracks the wearer’s eye movements with a webcam while a series of LEDs strobe back and forth in front of the wearer’s eyes. This is the fastest and easiest way to test for a concussion, and making this automated means it’s the perfect device to throw in a gym bag.
