Application

Design takeaway

Eliminate secondary or rare controls from primary interaction zones and cluster high-frequency triggers within the natural arc of the user's hand to minimize reach-stroke.

How to apply

Audit existing dashboards for 'dead space' used by infrequent controls; relocate those to secondary panels and compress the primary interface to fit within a 30-degree horizontal arm sweep.

Strengths & Limitations

Limitations

The study relies heavily on virtual manikin simulations (digital twins) which may not fully capture the nuanced haptic feedback or vibration stress experienced in real-world tractor operation.

Design Principles

"Hierarchical Task-based Spatial Mapping"

Traditional dashboards often prioritize machine-centric logic, forcing operators into repetitive stressful postures and increasing cognitive load. By centering design on task execution frequency, operators maintain better ergonomic alignment, reducing long-term fatigue and the likelihood of accidental triggers in complex machinery environments.
