Brain Pong

Brain Pong is exactly what it sounds like: the classic paddle game, except you move the paddle with your mind. It is a playful, surprisingly addictive way to get a feel for what a brain-computer interface can do — and a genuinely good party trick.

Under the arcade veneer is a real motor-imagery BCI. Imagine moving your left or right hand and the paddle follows. The first few minutes are humbling; by the end of a session most people are holding a rally.

Features

• Mind-controlled paddle driven by left/right motor imagery.
• Quick calibration that gets you playing in about two minutes.
• Difficulty curve from a forgiving practice mode to a fast arcade mode.
• Local high scores and a session replay so you can watch your control improve.

How it works

When you imagine moving a hand, your sensorimotor cortex produces a characteristic shift in EEG rhythms over the opposite hemisphere. Brain Pong learns your personal version of that pattern during calibration, then classifies it live to move the paddle up or down. The on-screen control bar shows the classifier’s confidence in real time, so you can literally see your intention turning into motion.
