Tools shape the way people work and function.

For instance, people are used to the set-up of a keyboard if they were to spend a lot of time using a computer. Many “short-cut” keys on the keyboard are designed for the user’s convenience. And these “short-cuts” are the ones shaping or even controlling people’s habits of using computers. It has been considered a good habit to press (Ctrl + S) to save the materials you are working on periodically. Thus, many people would unconsciously press Ctrl + S more than needed as if such action calms their conscious. A simple keyboard had its users forming various and numerous habitual hand gestures. And these common hand gestures perhaps provide people with some sort of comfort or excitement to a psychological level, and even therapeutic function.

A keyboard is only a small piece to the puzzle, there are also the handle of a joy pad, cell phone, steering wheel, etc.
