I'm not so sure, chorded keyboards have a fairly long history of being used by disabled users with mobility issues. The movement profile is going to be different compared to the lateral movements required for regular keyboarding. I can't find any studies looking into it though, so shrug. And this layout has more movement than the microwriter.
