Product Design Online Course Exercises Final Project from TUDelft

A showcase of skills and knowledge I’ve learned in Product Design online course by TUDelft through edX. The course was an introduction to product design that embodies the discipline of a user-centered design. The course was Holistic approach and the design methodologies mainly taught were contextmapping, user journey, personas, interview, brainstorming, design evaluation, selection using Harris profile, prototyping and testing. Interviews with expert designers were also conducted and to provide insights of how real-world designers solve problems and find solutions.

User Research

One of the most critical part in user experience or product design is the user research. On this stage, understanding the user is important, knowing the user’s goals, motivations and pain points is important. Empathy is one of the core principles of a user-centered design.



In the design activity on the right, the designer must identify the critical parts of his or her morning ritual. This activity helps early discoveries of existing problems that the user themselves aren’t aware of.


Problem Definition

Given the circumstances of keeping on loosing my focus and needing more time at work, the activity have helped me to create a problem definition to help me get aligned through all of the design process.


“How can we keep ourselves focused at work while doing other things that matters?”

Idea Generation

Generating tons of ideas at the early stage of the design process is better than perfecting a single or a few designs.


Design Sketching

Sketching also enabled me put my ideas on paper and share it with others for review and feedback. It’s a creative process of materializing your thoughts into the canvass.

The focus watch was the design idea I chose among the early generated ideas.

Low-fidelity Prototyping

Prototyping also allows you to test the feasibility of your ideas early on, you and your users would able to interact with your idea. Prototypes do not require to be high-end, low cost and common household materials may be used.

Functional Prototyping

In order to identify whether  your ideas would be feasible, a functional prototype is made. This is where the functional aspect of the low-cost prototype brought into life.

In reality, the Focus watch would require intense development on the engineering part but for the sake of simple demonstration, an Arduino was used to show the functionality of Focus watch using a simple display and Arduino UNO board.



Testing would help verify whether your design would work or some adjustments should be made. I have asked some friends to validate the idea of the Focus watch using some cardboard prototypes. It’s fascinating that people would interact with your design and provide you some feedback. This way, I have seen some pitfalls on my design which I could have never seen if testing did not took place.
