A. Touchless Keyboard

1. Pencil Operation gives hands the most relief.

   Each key stroke can be down by a pencil without any pressure needed to press down aything. The pancil can move as fast as the user wants without causing unintended key hits.

2. One hand operation avoids stress on many joints.

   This model is designed to be operated by one hand each unit. In this way, the keyboard can be placed to suit the natural direction of the hand and avoid the pressure on the wrist and shoulder. The keyboard can also be moved at will to avoid fixed static poture - another majore reason for body pains and RSI.

3. Two hands operate one keyboard.

   Some people realy want to use both hands to operate one keyboard. It is found that using one hand (right) to control most of the keypad, using 1 or 2 fingers of another hand (left) to control the other end 2-3 colums of the keys is also a comfortable and fast configuration for hands and wrists. But when 2 hands are confined to a fixed area, the old problems with the regular keyboards such as chest pain and shoulder pain may still occur due to the stress put on the chest and shoulder.

   

4. Two hands operate two keyboards.

   The best and fastest operation is to use both hands to operate 2 keyboards, one hand each. This way also avoids stress and pressure on many joints and gets all the fingers working.
