Perri Karyal, a video game streamer, has developed her own custom controller that reads electroencephalogram signals (EEG) to play video games. This device allows her to use the controller using only her mind, and does not require hands for any input. Karyal has previously explained that she designed this controller to recognize repeatable patterns in EEG measurements.<\/p>\n

That bit is achieved through electrical oscillations recorded from a headset that is placed on her scalp so as to simulate the act of pressing a button on a game pad or keyboard. Her creation came into notice when she started playing Elden Ring using her device. Karyal has previously explained that she has spent more time training the EEG than playing Elden Ring, and that\u2019s not an understatement as she had logged over 250 hours in Elden Ring back in May 2023.<\/p>\n
