Twitch streamer Perrikaryal has been using nothing but her mind to shoot up her enemies in Halo Infinite. Also, a psychology researcher, Perrikaryal, has swapped out her Xbox wireless controller for an electroencephalogram (EEG).
This powerful piece of technology reads the electrical activity in Perrikaryal's brain to detect her desired inputs. In conjunction with the EEG, Perrikaryal's setup also involves trackers that read her eye and head movements to control her Spartan's aim and motion in-game.
In a clip shared by Jake Lucky on Twitter, Perrikaryal shows off her hands-free skills, laughing uproariously as she guns down enemy spartans with nothing but thoughts and eye movements.
Perrikaryal's recent Halo Infinite triumphs come off of the back of her previous efforts in Elden Ring. In an impressive display of brain chemistry, Perrikaryal completed FromSoftware's famously tough action RPG using the EEG for all of the game's controls except movement. Though impressive, the streamer's entirely hands-free efforts in Halo Infinite are certainly a step forward.
In addition to taking names in Halo Infinite, Perrikaryal has also tried out her new setup in Overwatch 2 and Valorant. If you're interested, you can check out previous streams on Perrikaryal's Twitch channel.

As well as being impressive in and of itself, there's a noble goal behind Perrikaryal's work. Speaking with Kotaku, Perrikaryal stated that her aim is " to make the hands-free controller all-encompassing (all buttons and triggers accessible) and easier than a regular controller [...] so that anyone can use it for a comparable gaming experience."
Perrikaryal also revealed that she aims to up the ante by streaming Minecraft on September 12. Amusingly entitled "MINDcraft," the researcher also outlined how challenging this next project might be: "A game like Minecraft is going to be an insane challenge because of all the menus that are required to navigate."
In order to reach the lofty heights required to navigate Minecraft, Perrikaryal has also been working alongside a “few labs and research groups... experimenting with biosignals [like blood pressure and heart rate] and EEG to integrate all of this into VR and a more immersive gaming experience.”
As well as being undoubtedly cool, these ambitions could have big applications for accessibility and, with luck, may lead to easier times for disabled gamers in the long run.
