LEVEL SELECTED
FlappyBlink
Exploring hands-free gaming for people with disabilities using EEG blink control.▼ SCROLL TO BEGINI wanted to explore how someone who cannot comfortably use a keyboard, mouse, or controller might still interact with a game. Blinking is a small physical action, but EEG made it possible to treat that action as a real-time input.
MAIN OBJECTIVE
Traditional keyboard, mouse, and controller inputs can exclude people with motor disabilities from games and other digital experiences.
Create a playable, hands-free game controlled by intentional eye blinks.
Tested electrode placement and blink-signal behavior using an 8-channel OpenBCI Cyton board sampled at 250 Hz, focusing on reliable signals from frontal channels.
Explored accessible gaming and hands-free interaction patterns to understand how alternative inputs can make digital play more inclusive.
Balanced sensitivity against false jumps: a lower threshold captured more blinks but made gameplay less stable.
WHAT I BUILT
Connected a blink-classification pipeline to Flappy Bird gameplay using a 1–15 Hz bandpass and 10 engineered features across two EEG channels.
Built a working prototype showing how biosignals can become an accessible, responsive form of game input.
For biosignal products, calibration and feedback are part of the user experience—not merely model setup.
