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.



Problem DiscoveredDesign Strategy01User ingores the metrics on the first page.

  • Prioritize last night’s outcome as the primary entry point with a visualized graph
  • Condense information on the home page

02User expects in-depth analysis on the detail page (when they click into the metrics), but will see the repeated content
  • Transform a collection of disconnected metrics into a clear narrative summary of the user’s sleep


03User can’t evaluate the importance of different sleep metrics.
 
  • Classify sleep metrics and break them down into different forms










Task 2

Understand Sleep Trend


As the app continuously collects users’ sleep data, it enables data scientists to derive meaningful sleep trends across defined time cycles. However, the original design used only a calendar view that encodes sleep scores with color, preventing users from perceiving patterns and changes over time. 

Problem DiscoveredDesign Strategy01User can’t perceive the trend over time
  • Have a weekly and monthly summary that compares different sleep metrics in a visualized way
  • Highlight positive and negative change by color and shapes

02The time frame is relatively fixed
  • Add a calendar table to choose a time frame flexibly








Task 3

Achieve the Goal

 23% Increse DAU  


OZI Sleep connects 3D printed hardware with a mobile app to effectively improve users’ sleeping status. However, the current solution just plainly showcases the data rather than encourages users to achieve their original goal. 

Problem DiscoveredDesign Strategy01User is unclear about personal goal.
  • Compulsively force the user to set their sleeping goal monthly

02Plain data is boring to check every day. User seldonly use the app.
  • Add Sleeping Insight compared to their goal
  • Sleeping assistant that intelligently anaglze their behavior and trend.
  • AI-generated Sleep Music that could play during sleep in the integrated pod
