Quant Self Intervention

Assignment 05: Quant Self Intervention

Design or prototype an intervention that would help you to change your behavior based on the data you’ve gathered or based on the service you designed in you Quant Self Service. Tech or community or social based interventions are fair game.

  • make your intervention tangible; make it visual or physical in some way.
  • justify how your intervention works and why it is convincing for you and why it might (or might not) be a useful strategy for others.
    You might consider: – paper prototypes, a slide deck, a screen dummy, video, etc – using your quant self service idea as a foundation to build your intervention on

Language Usage Tracking

The following application only focuses on writing thorough keyboard in either mobile device or pc. If you are a new user, it will ask the access to data about when you change your language, because it can be sensitive information. Once the user confirms, it lands to the Welcome (Get Started) page and will set up language types and devices to synchronize.


After the registration, the application won’t ask accessibility question unless the user desires to stop the process of collecting data. Instead of Welcome page, now it will directly land on profile page and shows the average usage of different languages, list of languages, and list of synchronized devices. This page also has a role as setting page, so any visual change, language and device reset can be done in here as well. In order to see more details about data, tap the left top button and it will land on Time Map page. The default view of Time Map page is daily based.

Time Map

Once in the Time Map page, the user can navigate to further information as weekly based, monthly based, or yearly based data. Each page’s graphic is color-coded according to language, which is adjustable element in setting page. Through these Time Map sections, the user can discover such aspects like: “I use more Korean during weekends”, “English is my main language while I’m not on vacation”, and “My usage of English is increasing every year”.

Assignment 05: Reflection

A short paragraph or phrase on what you learned this week.

There has been some confusion on the order of documentation posts, so I merely spent time reorganizing and making some updates on existing posts. The previous comment by Joey on assignment #6 is now under the proper post as a copy. It is definitely my mistake to carelessly overlooked the assignment details. On another hand, I realized that my assignment #4 and #5 were in a combined form after looking at some other classmates’ work – and how I’ve been often thinking user research and design as one chunk of practice, but they’re not.

It’s important to conduct user research in isolated manner from the design work itself, especially to keep objective view in both areas. One of the best ways to increase accuracy is testing many users as possible – which wasn’t an option in my assignment #4, because I was the only user to form the persona figure. At the same time, I’m aware that this service is targeted towards very limited user pool: people who speak more than one language. However, I still decided to proceed the idea regarding that this class is more about “I” and personal data.
