[Prototype] Kazu, A Multilingual Counting App Using Paper Prototyping – Mai Saito

Kazu is a multilingual app that helps users to learn numbers in 6 different languages (English, Spanish, Mandarin, French, Arabic, and Japanese). Kazu‘s name comes the Japanese word for number.

The process began through paper prototyping. I sketched out a scrolling interface that acted as a simple yet interactive single paged app. After conducting user tests, I found that the audiences reacts well to the experience. My initial idea was a plant growing game, but has the same idea of progression to my Kazu prototype.

My other paper prototypes were not as successful because the path was not as clear for the user to follow. Through the failed tests, I found that the interface has to clearly show what leads to what. With the second stage in prototyping, I focused on aiding the user in understanding how to navigate through the app easily.

The main page has the title to introduce the audience to the app. The arrow and the zeros that sit at the top of the screen suggest that there is more content, letting the user know to scroll. The slight color gradation also encourages scrolling and makes the experience more dynamic.

As you scroll through the app, the highlighted/upright numbers are clickable which leads to a pop-up tab that shows the translations of the number. An “x” icon then returns the user to the main sequence.
