Sleepdream is a smart sleep solution composed of a patented radar sensor, a smart pillow, and a mobile app.
Despite its advanced technology, many users struggled to understand how the system worked and what impact it had on their sleep. Ahead of the Version 2 release, the PeopleMulti team engaged me as a UX consultant to identify and address these gaps in user understanding.

Current App Analysis

Key functions are buried in complex layouts,
preventing older users from understanding product benefits
Information Overload
Too many metrics are displayed on
a single screen, making it difficult to
grasp the key insights.
Visual complexity
Small text, multiple colors, and numerous
icons used at once make the interface less
intuitive, particularly for older users.
Lack of meaning
the interface does not clearly show
practical value.
Users are unsure whether the device is properly connected to the app,
leading to doubts about whether data is being collected or features are active.
Unclear Color Guide
Current color indicators are difficult for seniors
to notice and inaccessible to users with red–green
color vision deficiency.
Users couldn’t understand how the tracked data led to better sleep
due to a lack of in-app interpretation or guidance.
Charts present raw numbers, but users cannot see how these metrics relate to better sleep quality

Internal Stakeholder

Interviews

Users often call customer service due to insufficient information in the app,

including questions about where to find specific details.

The absence of in-app device status information makes it impossible to diagnose customer device

connection issues, as neither support staff nor the customers themselves can identify the source of the problem.

While the customer service team lacks visual information to guide step-by-step issue resolution,

leading to diminished trust in the device.

Disappointed customer reviews reveal a disconnect between the product's marketing as a sleep solution

and its actual effectiveness in reducing snoring, which was the primary expectation for many buyers.

Turn raw data into clear insights

Development Iterations - Clarify device connection & guide troubleshooting

To resolve major connection uncertainties, I prioritized the

[Testing Device] feature, which scored high in user value despite higher complexity.

To help users resolve device issues more intuitively,
I explored three Testing Device iterations of the device control interface

Empowering troubleshooting through focused status awareness and clarity

Development Iterations - Turn raw data into clear insights

To make the experience more accessible and supportive for older users,

the Sleep Feedback feature was iteratively refined through three key design directions

By narrowing the focus to a single key behavior,
the final iteration avoids overwhelming users in a clear, supportive format
