Case Study
Vocabulary is essential. It's a fundamental asset in our lives that is often overlooked. We, as humans, are constantly learning, whether we realize it or not. Although there are many vocabulary apps in existence, most of the users I talked with couldn't name one they frequented often (aside from Google), even though they enjoy learning and seek knowledge often. For this reason, I thought Vocab Bubble, a Word of the Day app for people with limited time available to learn something new, could be very beneficial.

Key Research Goals
-
Find out how users learn new information and what sources they're using to learn that new information.
-
Define the issues users are currently having when attempting to gain new knowledge.
-

-
Analyze all findings from the research.
-
Sketch out low-fidelity wireframes based on features that are important to the user.

-
Continue testing and iterating until all confusion and pain points of the user have been deleted.
Competitive Analysis
During the Competitive Analysis, I took a look at 3 vocabulary apps...Vocabulary Builder, Lexilize Flashcards, and Flashcards. There were pros and cons to each, but I did realize that an app with the features of Vocab Bubble doesn't really exist, which is always an advantage when your competition is low.

Vocabulary Builder
Although it took a little time to become familiar with the app, the personalized study experience if preparing for a specific exam is very nice. The aesthetics of the app could have been a bit more appealing, but the simplicity doesn’t distract the user while studying.

Lexilize Flashcards
This app doesn’t have a language translator option for phrases, but this is great for a beginner who’s looking to learn a new language. The graphics and colors used are eye-catching, while also being soft and warm.

Flashcards
While this app could be quite time-consuming for the user to add each flashcard they need, the reward is worth it. It becomes a customized study tool that will help the user greatly. This app is a very basic design, with little-to-no bells and whistles. It could benefit from a little bit more color, but it isn’t necessary.








Interviews
With the limited time I had to conduct the research, my main source for collecting user preferences was going to be through interviews. I interviewed 5 participants about their methods of learning new information. My goal was to understand how and why people use the references they do to educate themselves, figuring out the features and functions that would help the average user of this app.

Interview Conclusion
After talking with the interview participants, I was able to concretely settle on the features that are most important when learning new vocabulary. The participants are interesting in a flashcard feature, a simple design with calming effects, and straightforward functions without unnecessary buttons and tabs.
Task Analysis & User Flows
Vocal Bubble is a simple to use app with a straightforward objective; however, within the scope of vocabulary, it has all the features and functions the user will need.

Low-Fidelity Wireframes
With the features set, I crafted low-fidelity wireframes to begin constructing visuals for the concept. I then took them from paper to computer for the usability tests.


Usability Testing
After creating the low-fidelity wireframes, I put together a clickable prototype of a few tasks and conducted the first round of usability test to gauge whether the design and layout was working for the user. I came away with some invaluable feedback and applied it to the subsequent wireframes.

Findings

Visually pleasing Flashcard pages, but it would be nice to have another way to study. I created a Multiple Choice option for those that prefer that method of studying.
The Heart button (Save) was hard to find. Recommendation from users was to rearrange the Word of the Day screen to make the heart more noticeable.
Having two Heart buttons on the same page was confusing. Users suggested creating a menu at the top of the page for navigation.


Structure of the Study page was confusing. Taking into account what the participants said, I rearranged the page, with the question up top and the two choices below, with a CTA button to continue on.

Icons were easy to find and understand, but the layout needs work. To address this issue, I played around with the layout for optimal simplicity.
Key Research Goals, Revisited
-
Find out how users learn new information and what sources they're using to learn that new information. The consensus of all users I spoke with was that Google was their go-to resource for learning new information, with a couple adding Wikipedia. Nobody had a vocabulary app that they frequented often.
-
Define the issues users are currently having when attempting to gain new knowledge. Being short on time and busy, as well as finding the apps and sites that are easy to use on-the-go, were the issues most individuals had when attempting to learn something new.
-
Plan out which research methodologies to use for this project. The two research methods I used were user interviews and usability testing. Due to some time constraints, I wasn't able to conduct any other methods.
-
Conduct and complete all research methodologies agreed upon in previous goal. I conducted 5 user interviews and 1 round of 3 usability tests.
-
Analyze all findings from the research. After conducting the user interviews, I was able to create wireframes based on user's wants and needs.
-
Sketch out low-fidelity wireframes based on features that are important to the user. An important feature that I made sure to add in the design was a fast and simple app that will give daily information that someone can learn on-the-go.
-
Lead usability tests to establish what is working and what needs to be adjusted. I was reminded that not everyone learns the same way. With that suggestion, I added a Multiple Choice option as well as the Flashcard feature.
-
Continue testing and iterating until all confusion and pain points of the user have been deleted. Next steps would be continuing on with additional usability tests until all pain points and navigation issues/confusions are addressed. After which, high-fidelity wireframes would be designed and A/B testing would be conducted.
Lessons
At the beginning of the Vocab Bubble research, I was not quite sure what kind of vocabulary app I was going to create. A couple options came to mind, which included a Language Translator app, Learn a New Language app, or a Word of the Day app. After speaking with people who regularly enjoy learning new things, the consensus was this: a Language Translator isn't necessary because Google is so easy to use for this feature. The Learn a New Language app would have taken too long to learn, therefore wouldn't be a quick option to gain knowledge. But the Word of the Day app was intriguing. It's something that Google doesn't necessarily do, and the potential users weren't familiar with any other apps that were WOTD, so the market wasn't as competitive. Gaining insight from participants in all stages of the research process was crucial to learning what type of app would be most utilized.
