Flavor Explore: Rapid Prototyping and Evaluation of User Interfaces

Expert-evaluation methods, such as cognitive walkthrough and heuristic evaluation, are widely used in user experience studies due to the reason that it can identify usability problems early and fast and find areas for improvements. In this paper, we present evaluation of Flavor Explore, a high-fidelity prototype, aiming at searching for delicious food and nearby restaurants. A taskbased evaluation was conducted to evaluate primary search tasks of the prototype, which included five experts with the background in interaction design and two potential users. Twenty two usability problems were then identified. The findings were helpful for improving the design and for further research.
