Tips on Prototyping for Usability Testing
Because user research studies peoples’ behavior, the most effective research techniques involve observing participants doing things and talking about what they’re doing. Research that focuses on opinions and discussions of behavior in the abstract isn’t as useful, because it’s difficult for people to talk about their behavior out of context or to evaluate a design without using it. Therefore, the best way to evaluate a new design is to create a prototype and give participants something concrete to interact with and react to.
