At the beginning of the project, the hardware design was still undefined. The only feature that had been agreed upon was a circular display. I began making explorations of how things could work and created a few interactive prototypes to do some guerrilla testing and facilitate communication of the concepts.
The thermostat design was further refined by the Bosch team and a companion app was developed following the same look and feel that we had designed. The product was successfully introduced to the market in The Netherlands and Germany where it gathered good reviews from consumers, and it won several prestigious international design awards.
