There have been fMRI studies of people looking at images plus
algorithms to figure out what the people are looking at. These hit the
news and people immediately called it "mind reading" (it wasn't really
mind reading). For transcriptional purposes, maybe it's sufficient?

Here are some papers on the subject.

That's like trying to type with a hammer.
