Habit formation

“

Persistent use of any interface will cause you to develop habits that you will find yourself unable to avoid. Our mandate as designers is to create interfaces that do not allow habits to cause problems for the user. We must design interfaces that

1. deliberately take advantage of the human trait of habit development and
2. allow users to develop habits that smooth the flow of their work.

The ideal humane interface would reduce the interface component of a user’s work to benign habituation.
