A desktop applications for technical engineers to design interfaces for a Dynalite sytem (smart home system) Dynalite is a smart home lighting system that allows many control options. The system can be applied in various situations, from large homes to hotels. Companies that offer the system need to be able to create customized user interfaces. The challenge was to offer a tool that allows both maximum flexibility, as well as guides the user to create interfaces with a good usability and good esthetics. Through user interviews and prototype testing we learned how to balance the two. My contribution: • User interviews • Prototype testing • Interaction design • Concept creation
