After testing our prototypes with over 300 kids for our Move Kit, we learned that kids love technology that is portable, reactive and open-ended. This allows them to be engaged and active, while having fun. We used feedback from kids to define the form factor of the Mover Kit, which, after testing and iterating, became a wearable. The technology we chose––motions sensors, a compass and rainbow lights––gave kids a responsive, active and stealth learning we were after. And they wanted to keep using it again and again. As we continued to develop the product, we got even more excited that this wearable was not a smart watch, not a fitness tracker and not about data in a cloud but about something very clear–– kids learning through active play.
