Mouse miss-match with finger dexterity

Fingers move finer than wrists. Wrists move finer than hands. The subtlety of human muscle control is Fingers>Wrists>Hands.

All the human great tools in the history, scissors, chopstickes, pens, etc rely on and take advantages of synthesis of finger/wristshands.

Traditional computer gadget, Mouse, failed to take advantage of human muscle natural powers, because

  1. Mouse uses wrists/hands for pointing and finger click for commanding but pointing requires more subtlety than commanding.
  2. Hands for point and finger for commanding are separately used and they are not the synthesis of each powers.

Microsoft Surface dial looks to try taking advantage of finger for pointing too. If it is true, it would be one of great progresses from the mouse.
