This idea was, at first, about creating a way to use the computer that doesn't use the hands. I though about it because my hands were killing me someday.

Then I had the idea to create a pedal, like a guitar pedal, that would do certain repetitive tasks: close a window, click, it really sould be something you do a lot.

The uiltimate goal of this idea is the direct neural interface. Talk back and forward with the PC by sensing your thoughts, with the least delay possible related to the interface. It should be wicked.
