Neuralink – Elon Musk’s company that deals with brain implants for the control of electronic devices via neural signals – has published online the video game it used to test the results of its first human patient, Noland Arbaugh. The game is called Webgrid And you can find it here.
The idea behind the game is simple: you have to click on the blue illuminated square inside a large chessboard. The trick is to do it as fast as possible without errors and thus obtain a score calculated in bits per second (BPS) which in turn derives from the net value of correctly selected targets per minute (NTPM) and the size of the grid.
Arbaugh was able to get a rating of 8.01 BPS (49 NTPM) using only your mind. To give you a point of reference, playing with a regular mouse we achieved a score of 11.77 BPS (72 NTPM) after a couple of tries. We are sure that many will be able to do much better with a little training. What is your result?
Details on the Neuralink and Arbaugh study
The implant (known as N1) in Arbaugh’s head is designed to detect the 29-year-old quadriplegic’s brain activity and transmit the resulting data to a Neuralink application, which translates neural signals into actions that can be performed on a computer. Neuralink is currently working to improve the implant’s performanceso as to grant Arbaugh the ability to wield a computer cursor with speed and accuracy that rivals the performance of an average Neuralink researcher using a physical mouse.
Neuralink provided an update on Arbaugh’s progress 100 days after his implant surgery. The company revealed that Arbaugh used the brain-computer link to play a variety of video games, including Mario Kart 8 Deluxe, Slay the Spire and Sid Meier’s Civilization 6 during his free time, beating even non-quadriplegic friends.
