Play Webgrid
At Neuralink, we use a game called Webgrid to test how precisely you can control a computer.
The goal of the game is to click targets on a grid as fast as possible while minimizing misclicks. Your score, measured in bits per second (BPS), is derived from net correct targets selected per minute (NTPM), grid size, and the number of click types.
Our clinical trial participants have achieved over 10 BPS controlling a computer with their brain.
