Making a physical prototype for a video shooting.

After the user test, I iterated the design and projected it on a desk to know it’s look and feel in an actual environment. I noticed a few texts and elements ware too small to tap. I adjusted visual details after this prototype.

Interaction video

While developing a prototype, I needed user’s feedback about the system to go further. I created a paper version prototype that imitates the digital prototype. There were three people who participated in the test and I wanted to observe a few aspects.

Q1. Many options vs Limited options for data connection

Reflect’s whole system consists of three parts: Initial setting, Daily reflection, and Archive.

Initial setting

To use Reflect, users have to connect it to their mobile phone. Once Reflect is connected to the phone, it collects data such as photos, location, calendar events.

While researching, I realized journaling is based on habit. Even though there are great services that help people write journal, if it doesn’t become a habit, it’s not easy to continue. So I started to study the science behind the process of habit formation and found a great framework called “The 3 R’s of Habit Change” from this article written by James Clear.

Even though names of frameworks are slightly different, the pattern of habit formation follows the same cycle and has been proven over and over again by behavioral psychology researchers such as BJ Fogg(Stanford professor) and introduced in…


Things to improve from ver.1

  1. What types of data the system will use?
  2. Smart home/interactive desk? Why?? Why not app only? — need story
  3. Include emotional moments in curating/revisiting part

This is an exercise to identify the strong and weak points of competitors in Life Documentation market. From paper journals to smart photo apps, there are tones of products out there. I realized all they have different characteristics and directions, and it depends on the value they pursue.

I also placed my solution in the chart for comparison.

Finding gaps: Google Photos vs My solution

Value proposition

Memory Universe is a personal memory archive app for people who want to curate their life experience easily. Unlike other journal apps, Memory Universe is based on auto-created entries from your personal data and designed to cultivate habits of self-reflection.

Product Lifecycle

  • Experiencing: Our life is filled with experiences. We are often excited, angry, sad, happy and more. And sometimes we want to capture this experience to remember.
  • Recording: We record by writing journal, taking pictures, posting on social media, and tracking our activities.
  • Organizing(Curating/Prioritizing): Since there are large quantities of records, they have to be organized. Usually machine do it for people now.
  • Revisiting: People often revisit past memories for various purposes. For personal reference, for self-reflect, or for just fun.
