Behavior learning is a key part of design research nowadays, and I would like to strongly mention observation. When Dreyfuss and his team realized that the users won’t just stay in where the phone was placed, they reduced the weight of the princess phone and made it portable. The insight is based on observation.
Here is the reason why observation is so important. For users sometimes act without consciousness, which means that they may not realize they had done or haven’t done something, they won’t tell their behavior during a survey or interview. To receive more information and evidence to support the design function, designers and researchers should go outside and observe humans behaviors. Never stay in front of the desk and pretend to know users’ behaviors by the secondary research because it’s never enough, or right.
