Contactless Sleep Sensing in Nest Hub

Contactless Sleep Sensing in Nest Hub | healthcare technology | Scoop.it

People often turn to technology to manage their health and wellbeing, whether it is

  • to record their daily exercise,
  • measure their heart rate, or increasingly,
  • to understand their sleep patterns.

 

Sleep is foundational to a person’s everyday wellbeing and can be impacted by (and in turn, have an impact on) other aspects of one’s life — mood, energy, diet, productivity, and more.

 

As part of Google's ongoing efforts to support people’s health and happiness, Google has announced Sleep Sensing in the new Nest Hub, which uses radar-based sleep tracking in addition to an algorithm for cough and snore detection.

 

The new Nest Hub, with its underlying Sleep Sensing features, is the first step in empowering users to understand their nighttime wellness using privacy-preserving radar and audio signals.

 

Understanding Sleep Quality with Audio Sensing

The Soli-based sleep tracking algorithm gives users a convenient and reliable way to see how much sleep they are getting and when sleep disruptions occur.

 

However, to understand and improve their sleep, users also need to understand why their sleep is disrupted.

 

To assist with this, Nest Hub uses its array of sensors to track common sleep disturbances, such as light level changes or uncomfortable room temperature. In addition to these, respiratory events like coughing and snoring are also frequent sources of disturbance, but people are often unaware of these events.

 

As with other audio-processing applications like speech or music recognition, coughing and snoring exhibit distinctive temporal patterns in the audio frequency spectrum, and with sufficient data an ML model can be trained to reliably recognize these patterns while simultaneously ignoring a wide variety of background noises, from a humming fan to passing cars.

 

The model uses entirely on-device audio processing with privacy-preserving analysis, with no raw audio data sent to Google’s servers. A user can then opt to save the outputs of the processing (sound occurrences, such as the number of coughs and snore minutes) in Google Fit, in order to view personal insights and summaries of their night time wellness over time.

Studies show that CBT-I delivered digitally through mobile phone apps is effective in treating # insomnia.

Studies show that Cognitive Behavior Therapy for Insomnia (CBT-I) delivered digitally through mobile phone apps is effective in treating insomnia.

 

Like a real therapist, the apps that use Cognitive Behavior Therapy for Insomnia (CBT-I) also provide practical tools to help the user worry less about their sleep and over time, be less anxious and more confident about their ability get a good night's rest. It's very similar to what physicians do face-to-face with patients,

 

And a recent study of Sleepio by Ong and the team that developed the product found that participants who used the product reported an improvement in insomnia symptoms and overall wellbeing.

 

However, these apps don't work for everyone.

 

The recent study hints at why. Less than 50 percent [of people who were assigned to use the app in a randomized controlled trial] are able to make it through the entire course of CBT delivered through digital platforms, For some people it may be hard to make it through all the sessions of CBT.

 

This is true of most health and wellness apps.

 

In other studies it has been found that of the 10,000 mental health apps out there, very few are actually being used.

 

We dont really understand how people are using technology towards their health and recovery,

 

But in some ways, he says, people with insomnia may be ahead of scientists in figuring out what works well for them.
