Document Summary

Perceive, act and react to events around us. Drive a car, read a book, have a conversation. Things that we do without thinking about them. Fast, require minimal attention, unavailable to consciousness. Not affected by limited capacity of brain and don"t require attention. Can change relatively easily compared to automatic ones. Goal 1: use of the interface should capitalize on automatic processes, so that users conscious thinking focuses on the actual goal they are trying to achieve. E. g. their novel rather than how to type it in. Goal 2: automatic processes are difficult to unlearn, thus once established should better stay as they are. Most relevant to interaction design are the first three. How information is acquired from the world and is transformed into experiences. Based on the idea that groups of stimuli lead to new things that are distinct from the sum of their parts, i. e. have distinct gestaltqualit t (form-quality).
