Sleep SensingContactless sleep & respiratory wellness sensing for Nest Hub 2
At Google, I led design for Sleep Sensing for Nest Hub (2nd Gen) features, which focused on creating a non-intrusive, ambient experience that helps users understand and improve their sleep patterns. This project involved developing a system that passively monitors sleep through motion and breathing, providing personalized insights and recommendations.
Sleep sensing
Utilizing Soli radar technology Motion Sense, we enabled the Nest Hub to detect movement and breathing without the need for wearable devices or cameras. This approach respects user privacy while delivering accurate sleep tracking, allowing users to gain insights into their sleep quality and patterns effortlessly and detect sounds like snoring and coughing and environmental factors like light and temperature in the room.
Sleep summary
Each morning on your display, you users get a sleep summary of how well they slept the night before. This includes elements like Quality, Duration and Schedule, and displays an overall color for how well or poor sleep was overall. The system provides tailored recommendations to help users improve their sleep hygiene. By analyzing sleep data, it offers suggestions on how to adjust routines and environments for better rest, integrating seamlessly into the user’s daily life.
Through this initiative, we aimed to make sleep tracking more accessible and less intrusive, empowering users to take control of their sleep health with minimal effort.
Respiratory wellness
I led the Respiratory Wellness effort, which detects respiratory and environmental factors that can affect user’s sleep
Respiration rate (RPM): Measures the average number of breaths you take per minute, and how variable your breathing was in that sleep period. Your RPM range is the top 95% and bottom 5% of the night’s data.
Sleep disturbance events: Shows disturbances during sleep such as coughing or snoring.
Personalized sleep insights
As Sleep Sensing gets to know user’s sleep habits and patterns, they receive personalized insights and recommendations to help improve their sleep.
I also led the design for the sleep report — a summary of insights, education, and tips related to sleep. Insights are things that Nest Hub noticed about a user’s recent sleep that could be improved. The report also includes education from third-party sources, explaining reasons for the insights and tips on how to improve.
