Counting steps was just the beginning. From fitness bands to clothing – worn during exercise, all day and in industrial settings – technology continues to advance to track sleep patterns, caloric intake, peak level and resting BP, post-exercise recovery, insulin levels and more. We typically think of this data in a closed circuit between device and consumer, but it takes on an entirely different context when shared with marketers, retailers, health care providers, and insurance companies. How do consumers feel about sharing this data? How are brands approaching the ask, gaining consent and maintaining trust? What data is being used? How is this data being applied with other datasets to gain insights? What does the future hold?
