This is great work and the authors should be really proud. The hard thing about BCI research is that it has to compete with operating a joystick with your lips

This is great work and the authors should be really proud. The hard thing about BCI research is that it has to compete with operating a joystick with your lips. Quadraplegics get incredibly good at this, to the point that they can play RPGs: https://www.youtube.com/watch?v=qj6tFWs1bhg https://www.youtube.com/watch?v=qj6tFWs1bhg Perhaps BCIs will eventually get so good that they will be superior to these joysticks. Then quads will be able to play first-person-shooters :)
