Why do i want to write about something so simple? because it's genius! it's ergonomic, quick and it's really hard to choose the wrong letter. All console producers should take an example from that, it make's life so much easier (except wii, there we have a good motion typing design).
This design is based on a very old concept used by disabled people that cannot move even their eyes, it's based on the mental keyboard
I saw this concept presented by Klaus-Robert Müller, the only one with the shower in his room at the berlin university because the EEG gel is needed while wearing this EEG cap. I saw him presenting this concept on google developer days in berlin, during his lecture mashines that learn, i think steam have seen that presentation and used it in a way that will be original yet based on the same idea.
