HCDE 210: Interaction Design (IxD)

“Interaction design (IxD) is the practice of designing interactive environments, digital products, systems, and services.”

This was our first sprint for the HCDE 210 class. But today we got introduced to the field of Citizen Science, which is scientific research conducted by amateur or nonprofessional scientists. We had to design an app for citizens who might want to use the app to check the water quality of the Puget Sound area.


We first determined the specific projects that people might be interested in to collect the water quality of the Puget Sound area (for example, the levels of pH, temperature, salinity, oxygen and other molecules in the water) to get a project in our minds. We then ideated the types of people or citizen scientists for whom we were supposed to design for. This was important for the next step, which was to think why these citizens might be interested in collecting that data. I chose “swimmers and other water sportspeople” as my choice for citizen scientists, since they would want to check the quality of water they want to swim in. We then got on to designing the app. We started with an interaction flow chart and finally drew screens for the app.

My Experience

This was an interesting experience for me, especially thinking about citizen scientists, which was a fairly new term for me. Another interesting thing was to think about how to interact with the app, which I felt was the main idea of Interaction design. I also made a friend of mine use the app, and figured some of the design flaws of my app which could make it difficult for the user to use the app.

What I liked about this project

I found the POP app pretty interesting. But as I was making my own POP app for this class, I realised how the smallest things in an app are based on many decisions and rely on a lot of thinking, brainstorming, planning, designing, and testing. It was also interesting thinking about citizen science, which seemed like an interesting concept.
