Course Description

After interviewing users, gathering requirements, creating a design concept, and creating and iterating interactive prototypes, it is time for the final stage of the human-centered design process: conducting an evaluation of the usability of your design. At this stage, we examine the interaction between the user and the interactive prototype to find out what improvements are needed in order for the design to achieve its goals. We do so by observing users as they interact with the prototype to complete tasks. While we often use a high-fidelity prototype at this stage, we must resist the tendency to consider the design as close to "done," as this stage of the process is still iterative. In order to get useful feedback and make the product better, we must carefully plan and conduct a usability test session, listen to the users, and make changes in response to design flaws that we find.

In this course, you will create a usability test plan, including defining its goals and any metrics you will want to use for your usability tests. Based on that, you will create a usability test protocol by choosing tasks and composing task instructions for your users to follow. You will then recruit a participant to run a usability test session with your high-fidelity prototype and form a plan for what changes you will make to improve your design.
