Fourth project milestone: Low-fidelity prototype presentation

For this milestone you will: create a low-fidelity prototype, do a cognitive walkthrough and small user test on that prototype, plan your medium-fidelity prototype, and then get started on implementing it. Incorporate feedback that you received from your instructors and peers (based on time constraints), and any further thinking about the design to develop a low-fi prototype. Use your list of requirements and your task examples to flesh out the details. (Normally you would incorporate all the feedback you received, which could involve starting from scratch with a new conceptual model. That is not practical for this project.)


  • Tools to use: Use a non-computational technique, i.e., nothing that involves scripted interactivity. If you are unsure of what technique to use, consult with course staff.
  • Scope and other dimensions: Your prototype should illustrate how your system would appear to the user. You should not be concentrating on visual appeal or completeness at this stage; rather, you are trying to show the overall interaction style and scope of your system.
  • Your prototype should contain the core views that illustrate how the system will work as a whole, with emphasis on the parts you are focusing on, including the interactions based upon the key tasks and requirements (from Ideate Milestone, part 1). The low-fi prototype does not need to capture every little detail, but it should capture the details that will dominate the experience of using it. 

Deliverable: Team Presentation

  • Document your prototype(s) using media of your choice.This illustration should document the main components of your design, and show how the prototype supports your task examples. E.g., you could create a narrated video demonstrating how a user completes those tasks with the prototype(s). If using photos, or something else, include annotations and labels as appropriate to ensure the demonstration is easy to understand.
  • Additional Information about your prototype.Identify which of the task examples you have chosen to support in your design. (Generally, your prototype should support at least 2 of your task examples.)
  • Justify the scope of your prototype and design decisions you made.

Length: Presentation duration will be based on number of groups/class time.
