Sanofi wanted to develop a pedometer with reliable data, which could be worn daily, especially in the office. We worked on different attachment systems and chose the one that allows it to be carried at the waist, the most reliable area for data measurement. We have made a simple and elegant design, making it easy to wear the pedometer to the office. In addition to the product design, we also designed the interface (data display and icons), as well as the design of the user manual.
