If you're looking for a way to use a computer more efficiently, researchers at the University of Waterloo's David R. Cheriton School of Computer Science may have a solution for you.
Master's candidate Jingjie Zheng and Professor Daniel Vogel have recently filed a patent that would allow computer users to trigger different shortcut commands by pressing the same keyboard key with different fingers, hands, or hand postures.
1 - People can use different hand postures to press the same key quickly and accurately across the keyboard using both hands.
2 - People like the index finger and the thumb with other fingers closed most. They are the fastest too!
3 - People don't like the ring finger and the middle finger both with other fingers closed. You could probably imagine why.
4 - Using different postures are as fast as different modifier keys when pressing the same key to activate commands!
