As dreams go, this one isn’t that sweet. Some wearable sleep trackers are using customers’ brain signals to train AI without clearly telling them first. A review found that companies have gathered tens of millions of hours of brain recordings. Interaxon, which makes Muse headbands, trained one model on about 50,000 hours of data. The company says it removes names and other personal details before using the recordings.
It updated its privacy policy after being questioned and agreed that users should be clearly informed. Another maker, Emotiv, also changed its policy to explain AI training and the need for users to agree. More than two-thirds of the firms reviewed allowed data to pass to new owners without user consent. These models learn patterns in brain activity, but the devices cannot simply read people’s thoughts.
