How accurate are sleep trackers? Lawsuit says Oura rings have 'a coin flip's chance of being correct'
The class action lawsuit claims that Oura's sleep-tracking mechanisms sell 'faulty AI-based inference as reliable science.'
A lawsuit has accused the Oura smart ring of inaccurate sleep tracking, claiming its accuracy is akin to flipping a coin. The plaintiff argues that Oura's smart ring lacks the necessary sensors, such as brain waves, eye movement, cardiac activity, muscle movement, and a finger PPG, to accurately measure neurological activity that defines sleep stages.
According to the complaint, Oura's AI models are essentially making guesses based on improper inputs, leading to faulty AI-based inference being sold as reliable science to desperate consumers concerned about their sleep or health. The lawsuit, filed by Madison Surber, highlights the importance of accurate sleep tracking, as it is the foundation of the billion-dollar health wearables industry.
The court's ruling could potentially impact the entire industry, as sleep tracking is a key feature marketed by wearable devices like smart rings and smartwatches.
