"We have been using ProtoPie for a few years as a rapid prototyping tool. However, the experience was limited to evaluating smartwatch concepts on a phone or laptop screen. Now with the ProtoPie Smartwatch Solution, designers and researchers are empowered to explore concepts on real hardware, on the user's wrist, and in the context of use."
