Usability Research & Testing for the KLOA Keyboard iOS App

One of the classes that I took for my UW UCD certificate was Usability Studies (HCDE 517). I worked in a team with three other people to meet with a real-world client and run usability tests to determine: if people would understand the app in it's current state; and how interested they would be in using the app. We presented our summarized findings to the class and the client, and then met with the client to present our full findings and answer more questions in depth.

For this project, I was the liaison between our team and the client. I worked on the usability study kit, the usability testing and recording setup, data logging, video editing, and the presentation and report documents. We presented our findings to both the class and the client. 

Here are a few sample pages from our usability study kit, including part of the "affordance script" we created to be able to give consistent instructions to test participants.

The video below shows a participant interacting with the app in a small post test section. The video has been sped up until the point where the participant starts entering the last two words so that you can see the actual typing speed.

Below are sample pages from our usability study presentation. We presented to the full class as well as the main stakeholder, the client for our study.

And lastly, sample pages from our usability study report.

More information about this project

The app to be tested was a novel iOS keyboard concept for the new feature in iOS that allows replacements to Apple's default QWERTY keyboard. The Kloa app visually and mechanically differed quite a bit from other keyboards available for iOS. We ran impromptu user testing with friends and a random sample of people in bars to get a sense of how much they would understand, and quickly determined that we needed to create onboarding materials in order to get useful data in further testing.

I worked on the graphics for our usability study kit, and on many of the graphics for our presentation and report as well. We worked well as a team; collaboratively editing and planning via Skype and Google Docs.

I edited multiple video feeds from each study into one combined clip per study participant. One camera looked down at the phone, another looked directly at the participant, while we also recorded the video output from the phone. All four of us were then able to enter all of our notes from during the study as well as note details like timing and completion from the video itself. This let us see if the participants were improving over time in speed, completion, and more.
