Personal Health Record Project

When I was in Seoul National University, this project was carried out in collaboration with Seoul National University Hospital. We researched how to use personal health information big data meaningfully and created an application called PHR to protect people's health.

Detailed research promotion strategy

In order to proceed with the three-track study Which is more appropriate, a traditional UX research methodology or a lean UX methodology?

  • Traditionally, UX research goes through the above process.
  • As long as it takes enough time, it is stable and deep investigation is possible.
  • However, since it is difficult to review and evaluate the results of a long period of time, there is a risk of loss of agility and flexibility

Lean UX

In Lean UX, we start with a family we want to verify, create a prototype persona. After conducting a user survey to verify this, an MVP is created and verified, and corrected by the user.

Proto Personas

In Lean UX, the persona is not a tool for expressing research results, but a tool for best estimation.
Through ongoing research, we quickly find out how accurate our initial predictions were.
The persona can be easily adjusted, and the design can also be adjusted.

User Story

  • Through the user story, it becomes possible to define the core functions that must be implemented step by step.

  • Write a user story using a pre-configured prototype persona.

  • It is similar to a UX scenario, but the difference is that the task is to find the central function before user research.

MVP (Minimum Viable Products)

Wherever possible, except where unproven or unfocused, by allowing actual users to use the product with minimal functions, a tool to test the hypotheses you have thought of and learn from them

Outcome

The individual meaning of each of the lab data and lifestyle data could be grasped, but difficulty understanding what their relationship is and how they are of medical value when combined.

Lab Data - Biomedical Signal

  • Vital signs: Items that reflect changes in a patient's health status - pulse (heart rate), blood pressure, respiration, body temperature

  • Additional measurement of electrocardiogram, SpO2, etc. - More accurate understanding of physical conditions such as cardiac activity and respiratory system function

​

Lifestyle Data - Activity Data

  • A total of 100 healthcare wearables and application trends surveyed

  • Investigate what data can be obtained through wearables and apps, and how the latest technology trends are evolving.
