Activity trackers

Activity trackers came into popularity in the form of pedometers, first mass-produced in Japan by Y. Hatano in 1965. As technology improved, these trackers took different forms, including shoes, armbands, and MP3 players. Many of these early iterations were passive tools–someone might wear a pedometer on days they felt particularly health-conscious.
Now in the era of connectivity and IoT, we often expect our interaction with devices to be a two-way conversation rather than a dictation. That's why activity trackers are now designed and marketed with the intention of inspiring users rather than waiting for users to get inspired.
