How HMI displays impact operator productivity in industrial vehicles

The latest research indicates that well-integrated HMI (human-machine interface) systems lead to more attentive users that better retain task-related information and stay focused for longer with less reported effort. These systems also fit into the wider development trends in off-highway machines that affect operator fatigue in day-to-day tasks.

Operator comfort includes more than just the cushioning in their seats; it is everything that surrounds a driver as they operate a vehicle-steering wheel height, pedal positioning, seat support, harnessing and control interface. Research from Norway and Italy as part of an overall European Union study looking into HMI in heavy machines has shown the importance of ergonomics in reducing operator fatigue. Research from Markus Wallmyr, head of UX at CrossControl and a researcher with Mälardalen University in Sweden, has demonstrated the importance of display placement in improving information detection and the effectiveness of operator aids.
