Here’s a little background. At the age of 19, my son was in a serious car
accident. He had a head injury. He could not do anything for
He had an unusual way of communicating. Because he could not outright
say what he wanted, it took some different skills to determine his
Saying yes or no was something huge. I tried many inventions for him to
use. I don’t even remember some of them. I am proudest of the one
that I will show you.
The sketch is rough but you should get the idea. The whole premise was
that if he turned his head to the right the recorder would say YES.
If he turned his head left, the recorder would say NO.
The basic components were:
The base plate was attached to the head rest post.
The pivot arm turned right and left on the center post.
Two micro switches were hooked up to the two tape
A sweat band with Velcro on each side.
Two material straps to connect the headband to the pivot arm.
There were posts and shims and other parts to make this thing work. The
invention worked just the way it was suppose too. My son did not
like the headband so the invention went into the pile with the other
This was not a high tech invention, but one made for a specific purpose,
and it worked.
Is there a market for this invention? Probably not a big one. Medical
supply houses might want one on hand. I could not see filing for a
patent. I don’t think there would be enough demand for the cash
outlay. It could be a sale able product on a limited basis.
If there are any ideas you could use, have at it.
