What would you do to make a controller one-handed? Ben has moved all the buttons from right side to the bottom of the gadget controller under the fingers of the left hand. Although he had to move the batteries compartment to the right side but it is not that difficult.
Let us see how he did that: Ben placed the four right-thumb buttons at the middle finger, the right bumper he has placed at the ring finger. The right trigger was placed at the pinky. The left trigger was placed at the index finger. To be even more comfortable gadget the controller's left stick is placed on an extension that stays on your leg or any other surface to support the controller. So this is how you control all the buttons on the controller with only one hand.
The other nice thing about the modified controller is that it can still rumble. These gadget controllers will be very popular because they can not only be used by injured people but a normal person can use them. I think that it is comfortable because your right hand is free, for example when you eat, drink etc.
Very soon we might see these controllers in mass production, we hope so. However, before that happens all you got to do is order one from Ben Heck.
