This was a hackathon project my friends and I did in Spring 2017.
Our team decided to pursue a common goal, a common dream. We wanted to enable ourselves and others to do the impossible… TO SHOOT LASERS WITH YOUR MIND!!!
We built a game completely mind controlled android game that interfaces the Muse Headband. It uses the headband to read the alpha waves (~10 Hz) that indicate the general mental state of the wearer (either attentive or relaxed). In this the user charges up his or her attack by closing his eyes, then when an enemy is in front releases his attack by concentrating.
