Mind control isn’t possible, of course, at least not yet. But the idea of being able to simply ‘think’ a command to a computer system is an idea that has been around for a long time. Even Atari had the MindLink all the way back in 1984. It was a device you wear on your forehead to control Atari consoles and computers with your mind, or at least forehead muscles. It didn’t work, but at least the idea was there. The experience was intense! You can tell from this print advertisement, and the promotional video they made. Are these people having the time of their lives or WHAT?

These oddball devices notwithstanding, allowing people who are incapacitated due to injury or disease the ability to not just interact with a machine but through that communicate with other people is a noble and important cause, and the subject of multiple research projects going on today. Accessibility is one thing, with appropriate subtitles and font sizes and whatnot, but we are talking about being able to use machines with your mind.
