Touch-optimized User Interface Design for printing and control systems. For the machine and system developers Hapa AG and Laetus GmbH a common intuitive operating concept was created whose design adapts responsive to numerous panel sizes and mobile devices. The design has a clear visual information hierarchy and integrates seamlessly into the panel hardware. The modular navigation concept is workflow oriented and scalable up to plant management. Contextual help and assistance systems are an integral part of the user-centered interface. All contents can be adjusted depending on user roll, workstation purpose or machine configuration.
