I would think that the lag could be tweaked but who knows. I would love to try it but yeah it would probably be a little awkward. Maybe in time that could be our future RC remotes.
I had an idea similar to this a while back, but I just wanted a sensor for when my boy jerks the remote (like it would move the car) a second before a crash. His reaction is to pull it off course via the remote. He just has to teach his brain that there is no physical connection between the remote and the vehicle. Hahaha
If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
