My role<\/p>\n\t\t\t\t\t

Team project with three classmates. I did a big part of the user research, and together with a teammate merged it into the UI.<\/p>\n\t\t\n<\/div>\n

The goal<\/p>\n\t\t\t\t\t

Design an interactive product for top athletes. We designed ISCA, the Ice Skate Coach Assistant: an app for coaches of professional ice skaters.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n

The assignment was to design an interactive product for top athletes, to make their performances better. We were assigned Skate for Air, but we had a lot of difficulties with the research data provided at the start: the interview video wasn’t clear enough to use.<\/p>\n\t\t\t\t\t

So our focus switched to ice skaters in general. That gave us the insight that a lot of ice-skating training is still done manually.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n

Data is collected awkwardly<\/p>\n\t\t\t\t\t

Skaters use many apps that each collect data separately and don’t work together.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Skaters can’t fully focus<\/p>\n\t\t\t\t\t

They check their heart rate on a wristband while skating, instead of focusing on skating.<\/p>\n\t\t\n<\/div>\n

\n \t\t\t

Lap times come too late<\/p>\n\t\t\t\t\t

The coach keeps time with a stopwatch, and the data is only available after the ride.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/div>\n\n<\/details>\n\n<\/div>\n

Insight<\/p>\n\t\t\t\t\t

Skaters are mostly busy with lap times and heart rate, and have to hold a percentage of their power on longer distances. Yet lap times are only available after the ride.<\/p>\n\t\t\t\t\t

Interviews<\/p>\n\t\t\n<\/div>\n

Decision<\/p>\n\t\t\t\t\t

Live heart rate and lap times for the coach<\/p>\n\t\t\t\t\t

The app sends heart rate and lap times to the coach in real time, so the coach can see how fast the skater goes at what power, and give better directions.<\/p>\n\t\t\t\t\t\"Live\t\t\n<\/div>\n\n<\/div>\n

Insight<\/p>\n\t\t\t\t\t

We left the menu bar off the first screen so users would go through the connect flow first. In the first test round, testers found that unclear.<\/p>\n\t\t\t\t\t

Decision<\/p>\n\t\t\t\t\t

Show the menu bar from the start<\/p>\n\t\t\t\t\t

We added the menu bar under the Bluetooth screen. The second test round showed it added a lot of value.<\/p>\n\t\t\t\t\t\"Paper\t\t\n<\/div>\n\n<\/div>\n

Insight<\/p>\n\t\t\t\t\t

On the connect screen, an icon showed which device you could connect to. Several testers thought they were already connected.<\/p>\n\t\t\t\t\t

Decision<\/p>\n\t\t\t\t\t

Remove the misleading icon<\/p>\n\t\t\t\t\t

After removing the icon, the confusion was gone in the test with our target group.<\/p>\n\t\t\t\t\t\"Paper\t\t\n<\/div>\n\n<\/div>\n

Testing with real skaters<\/p>\n\t\t\t\t\t

Two of us had friends who skate or skated at a high level. They helped at the start, when the interview video wasn’t usable, and again to test the app. If they hadn’t been available, we would have gone to the Jaap Eden ice rink to find skaters there.<\/p>\n\t\t\n<\/div>\n\n<\/div>\n\n<\/details>\n\n<\/div>\n

“The feedback we got was overwhelmingly good for first-year students, because we did our own research, made a design solution and made decisions based on our users’ needs.”<\/p>\n\t\t\n<\/div>\n\t\t\t

We learned the most from testing: the first round gave us clear improvements for a better paper prototype, and the second round gave us small insights from our target group to add even more value. I still think the UI we made is pretty awesome.<\/p>\n\t\t\n<\/div>\n\n<\/details>\n\n<\/div>\n\n<\/div>\n\n<\/main>\n\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
