My Role
OZI Sleep is an innovative 3D printing bed frame company dedicated to serving both children and the elderly. I have partnered with (2) product managers and (2) developers to redesign the website and mobile app.

  • User Research
  • Wireframes
  • High Fidelity Prototype
  • Usability Testing















HMW Question

How might we
Ensure the (nighttime) readability for elderly users?


The OZI Sleep mobile app is designed for parents monitoring their children’s sleep and for elderly users tracking their own sleep stages via a smart bedframe. However, the current app can’t effectively communicate essential information due to a complex information architecture.













Painpoints


We collected feedback from 10+ current users aged from 35 to 65 and conducted 3 interviews to gain a deeper understanding of their pain points and needs.



Inconsistent Flows
The user flows that took our users from the landing page to any subpage had multiple points of friction or action buttons for the elderly.


Unclear Data Structure 
The daily, weekly andd monthly data and trends representation are not explicit for users, making it difficult for users to interpret patterns over time.


Low Sense of Engagement
The data is objective for users to relate to their personal sleep progress or feel a sense of accomplishment.













Design Strategy

Define Key Pillars of the Product



Professional Trustworthiness
Users need a consistent representation of the sleep metrics and professional data analysis with customized recommendations in the next step. In this case, they are more likely to trust the insight, follow the recommendations, or engage with in-app services.
Simplicity

The new design should prioritize ease of use and highlight the key insights.












Solution

Prioritize data through clear representations that emphasize trend tracking, enable one-tap navigation, and provide customizable insights tailored to individual user needs.













Design.



Task 1

Understand Sleeping Data


The user should be able to immediately understand what happened during the previous night upon opening the app. However, the original design has low information density and ineffective information hierarchy on the home screen, providing only limited insights.
