User research, Heuristic evaluation, Prototyping, User testing.

The principle of stress measurement in Kenkou is based on scientific research about the miscorrelation of breathing and heartbeat rhythms. To perform the measurement, the user holds their finger on the phone’s camera, which records the characteristics of the pulse.

Kenkou SDK's design process was highly iterative and included stages of research, ideation, content creation, prototyping, tech assessment, scientific assessment, user testings, etc. I was responsible not only for UX, but I also had to take care of the simplicity and scalability of the design system, as well as consider government data collection regulations, and scientific accuracy of the results and their interpretation.​

Supporting Kenkou's design, I had to solve various problems, both UX and technical:

• I made the design system flexible, scalable, and customizable for B2B clients using the Kenkou SDK.

• Limited B2B clients’ customization options to maintain consistency across the product.

• Designed ways to motivate users to share behavioral data, improving stress measurement accuracy.

• Balanced the need for comprehensive data with keeping users engaged and completing the flow.
