A great post by Jono of Mozilla Labs explains very well what should go into the design of user interfaces. Simplicity is the key and reducing the amount of friction between the interface and the user to a minimum. Keeping the number of options to a minimum while still allowing the user free reign to execute all desired tasks from anywhere in the interface is key to a successful design. Adaptive Blue’s blog also mentions Apple’s Jonathan Ive who says, “The task is to solve incredibly complex problems and make their resolution appear inevitable and incredibly simple, so you have no sense of how difficult this thing was.” (Leander Kahney, Inside Steve’s Brain )
