the berlin brain-computer interface group is currently presenting a live demonstration of their brain-
controlled pinball machine at the CeBit exhibit in hannover, germany. the project features a user wearing
a specially designed cap with eeg technology embedded within it to measure brainwaves. the user first
undergoes a training program to calibrate the machine to their brainwaves. 'while the player imagines left
and right hand movements, algorithms decode his brain activity signals in realtime into control signals
for the pinball machine'. once they have mastered the training regime, they are hooked directly to the
pinball machine. there, their brainwaves are linked to the left and right paddles so they can play the game
without using their hands at all.
