Assignment 8

Deadline: Tuesday, 20 June 2023 2 PM
Goals: Exploring your design space: Start building your high-fidelity prototype.

We now start working on the Hifi-Prototypes.

(1) List your various requirements elicited from the user research.

  • This step should be earlier in the process, as you know, but it is useful for focusing your work

(2) Decide based on your requirements and the insights from the low-fi prototype-testing what functionality to include in your high-fidelity prototype.

  • Consider your problem statement
  • What insights did you gain from the testing? What are your main takeaways?
  • Decide on an approach to select the most appropriate requirements (whatever appropriate means in your context)

(3) Define the major task flow you want to support.

  • Based on your scenario, describe at least two major task flows.
  • These descriptions will serve as task descriptions for the evaluators within heuristic evaluation next week.

(4) Start building your prototype. The UI should be clearly developed (consider all interaction, visual, and information design)

  • Ideally, you can iterate on your existing prototype in Figma.

Assignment 7

Deadline: Tuesday, 13 June 2023 2 PM
Goals: Understanding your design space: create an interactive low-fi prototype

By now, you have developed a thorough understanding of your project in terms of users, context, and tasks. You have also developed a good understanding of the problem you are trying to solve and an idea of what your solution might look like. Now we put it all together and enter the design space! You will begin to build your first testable prototype.

(1) Summarize the feedback you received on your storyboard.

During the last lab session, you collected feedback from your peers. Please summarize the feedback and document which feedback you will incorporate into your prototype.

(2) Develop an interactive paper prototype.

You will develop a low-fidelity interactive prototype that represents multiple states or views. Think about your persona who wants to use your product: What are the minimum needs of your persona? What are the must-haves?

Please describe briefly:

  • Your prototyping process.
  • The use case this prototype addresses.
  • How the storyboard is reflected in your prototype.
  • A self-assessment of the potential strengths and weaknesses of this first step into your design space.

Please make sure that your prototype is clickable and that other people can access your prototype for testing. Please don’t worry about what your prototype looks like! It is not about how nice things look, but about communicating a general idea and the main functionality.


Suggested process: Do just one more round on paper or a pad. Make photos and link your screens using:

  • Marvel POP (Prototyping on Paper)
    App for iPhone or Android
    This would be just enough for now and has everything to make your photos/screens interactive.
  • Marvel
    Web application
    One free project with max. 6 team members.
  • Figma
    Web application
    One free team project!
  • Invision (Prototype)
    Web application
    One free project with collaborators,

Other tools to consider: Sketch (Mac only!), AdobeXDAxure (30 day trial), Balsamiq (only a 30 day trial).

Assignment 6

    Deadline: Tuesday, 6 June 2023 2 PM
    Goals: Understanding your design space: create a storyboard

This assignment gives you the chance to deepen your knowledge in conceptual model building focusing on tasks. Furthermore, you will create a first prototype in the form of a storyboard.

(1) Formulate a problem and hypothesis statement and document it.

Please use the template (shown in class) introduced in the lab session:


[The name of your PRIMARY persona] needs a way to[user’s need] because [insight/goal]. We will know this to be true when we see: this quantitative/qualitative measure.


We believe that by [doing this / building this feature / creating this experience] for[the name of your primary persona], we will achieve [this quantitative/qualitative outcome].

(2) Create individual sketches.

  • Now it is time for solutions and first drawings!
  • Step 1: Look at your persona, your scenario and reflect on your problem/hypothesis statement, and focus!
  • Step 2: Each person in the team is drawing on paper (drawing on a tablet is also okay!) a solution he/she thinks would solve your problem.
  • Justify your first design rationales by documenting them using QOC.

(3) Share your sketches with your team.

  • Each person should present his/her first drawing to the other team members.
  • Select features and ideas you think should be part of your prototype.
  • You can use the dot-voting method again to make faster decisions.

(3) Condense your results from the previous step into a storyboard.

  • Check out the examples and hints on storyboards on the web…
  • You should not spend too much time with it, and your solution does not need to be perfect. We will continue working on that!
  • Synthesize your design rationales and document them using QOC.
  • This step aims to explain your idea/solution using the storyboard to your fellow students.

Assignment 5

 Deadline: Monday, 30 May 2023 2 PM
 Goals: Understanding your requirements by creating a persona and a
  1. Derive a primary persona from your data-gathering insights
    • Use one of the examples from the lecture slides as a template (or get inspired by the tools below).
    • Be visual, a picture is mandatory! (Do not forget to specify the image source.)
  2. Create a scenario that describes your vision of how your persona interacts with your
    • Use the example from the lecture as a template.
    • Highlight what and where.
  3. If you think you need to do more data gathering – go for it!


Assignment 4

Deadline: Tuesday, 23 May 2023 at 2 PM

This assignment requires you to develop a persona, scenario, and use cases. Building on that, we will wrap up by (re)framing the problem statement and hypothesis statement using predefined formats during the next lab session.

  1. Based on the feedback from the exercise, conduct three to five interviews.
    • Please document each interview (who you contacted and why). If you were not able to realize your interviews in one week, please use the next weeks. However, you must conduct up to five interviews in the next three weeks!
  2. Analyze your (qualitative) data using affinity diagramming
    • Conserve your clustering results, so you can go back to them if you need or extend them later on. You can use cards (paper) for it or tools such as Invision.
    • Document your process, by saving pictures (screenshots) of different stages of clustering.
  3. Connect your insights from the secondary data analysis and the interviews and review your project goals.
    • Highlight your main insights briefly.

Assignment 3

This assignment requires you to develop a better understanding of your project. We expect you to become an expert in your domain and understand existing challenges properly. In this assignment, you start with collecting data which will provide the foundation for the following weeks. Collecting data helps you describe the precise circumstances of the problem you are trying to solve. It is necessary to get to know your users and other stakeholders in depth.

Create the first part of your Data Collection Plan.

  1. Define the goals of your data collection session.
    What do you want to find out? These goals should be based on your project goals.
  2. Based on your goal, derive the stakeholders you want to collect data from.
    What are your stakeholders? Whom do you need to approach (i.e., who is indispensable for your achieving project goals)?
  3. Start with collecting information without approaching your stakeholders (so-called secondary data collection). Use existing websites, app information, and experience the app by yourself. Describe the app you are using in detail (who has developed the app, why, what functionality is available, how can people access the app, etc.)
  4. Prepare an interview study with your primary stakeholders.
    Name the stakeholders and explain, why they need to be interviewed. Explain, how you want to contact them.
    Justify the type of interview (structured, unstructured, semi-structured).
    Prepare the introduction and the closing session as well as the consent form as well as the questions (the interview should be 20 to 30 min long)
    Describe how you plan to conduct the interview (Who is taking notes? How do you take notes? Who is asking questions?)
  5. You will conduct a pilot study in the next exercise, thus, be prepared for this.

Deliverable: Summarize your answers in a blog post again! Use the provided template. Please ensure that the post is pleasantly layouted. For example, graphics and images are great (Lächeln)

Assignment 2

In your second assignment, you will reflect on your goals by finalizing the five W and reflecting on your values (Lächeln) Please also take the time and discuss with your team how you want to organize your collaboration.

I suggest the following procedure:

  1. Reflect on the feedback you received in class, the explored stakeholders, and their values.
  2. Read the article on „Humanity-Centered Design and think about the main insights. What values are important for you and your team regarding your project goals. Please describe those in about 100 words.
  3. Dive again into the material on the „ePA“ and on „DiGA“. Please add useful resources.
  4. Please answer the following questions (by reflecting on the feedback received in the exercise):
    1. What is the challenge you would like to tackle?
      For example, the registration process is challenging, the privacy policy is not well explained, and the utility of the app is not transparent.
    2. Why do you expect your engagement to be useful?
      Why is that an interesting problem?
    3. Who are your intended stakeholders?
      And who might be the indirect stakeholders?
      For example, elderlies, parents, people with a certain illness, etc.
    4. Where is your user group interacting with your software?
      For example, at home, in the hospital, or on the go.
    5. When is the user group interacting with your software?
      For example, only when being in the hospital, while biking, or daily in the morning.

Deliverable: Summarize your answers in a blog post again! Use the provided template. Please ensure that the post has a pleasant layout. For example, graphics and images are great
