Interaxon, the Canadian company behind the Muse sleep and meditation headband, has used about 50,000 hours of customers’ brain-wave recordings to train an AI model, it says. The recordings are collected as the device monitors brain activity and other body signals during sleep.
A Science investigation with the Pulitzer Center’s AI Accountability Network found that several companies in the field have gathered tens of millions of hours of EEG data to develop AI models, with policies initially failing to spell out that use. Interaxon says it removes identifying details such as names, email addresses and street addresses before using recordings.
Why it matters
Muse customers’ sleep recordings may be used to train AI as well as generate personal sleep reports, so people deciding whether to use the headband should check its current data policy; the supplied details do not say how users can opt out.
