Dennis Schaefer
HMI Specialist & Human-Machine Interface Designer
Dennis Schaefer is a senior HMI specialist with over 15 years designing human-machine interfaces for some of the most safety-critical systems in the world — from autonomous robotaxi operations to certified aviation avionics and military autonomy platforms.
What makes a great HMI designer?
Great HMI design connects operational context, human factors, clear system state, and decisive interaction under workload.
HMI work across aviation, automotive, and robotics
Dennis has designed cockpit displays, autonomous-vehicle operator tools, sensor-fusion visualisations, and mission-critical interfaces.
Safety-critical and mission-critical interface design
Failure states, uncertainty, workload, and recovery paths are treated as core product surfaces rather than edge cases.
HMI tools and methods
The work combines research, systems thinking, prototyping, real-time data visualisation, and close collaboration with engineering and operations.
