Chocolate Melting Machine - Interface Design (HMI)

For KREA Swiss, I designed the interface for a professional chocolate melting machine used in restaurants, bakery and high paced kitchen environments where precision and reliability are critical.

As the hardware was still in development, I worked closely with engineers and stakeholders to define the interaction logic, workflows, and system behaviour without a physical prototype.

My approach focused on systems thinking - understanding how temperature control, timing, and monitoring interact within real kitchen routines—and translating that complexity into a clear, glanceable interface.

I mapped user tasks, prioritized critical actions, and iterated on hierarchy, readability, and feedback to support faster decision-making during service.

Continuous collaboration with the engineering team helped align design with technical feasibility and hardware constraints while building a scalable and consistent visual language.

The final solution improved clarity, predictability, and ease of use, strengthening my ability to design for specialized users, complex systems, and cross-functional environments.
