01
Operator workflow
Define what the operator must see, acknowledge and control during real machine tasks.
Off-Highway & Mobile Machinery
Build the HMI around the operator and the machine.
Off-highway and mobile machinery combines operator workflows, machine data, demanding environments and long product lifecycles. Start with those constraints before locking the HMI platform.
What matters first
Clarify the product constraints before choosing components.
Use these questions to narrow the HMI workload, then compare compute, display, GUI and engineering paths.
02
Display environment
Set display size, readability, touch method and enclosure constraints from the actual operating environment.
03
Machine interfaces
Map controllers, sensors, vehicle buses and connectivity before the electronics are frozen.
04
Lifecycle & serviceability
Plan updates, diagnostics, replacement strategy and component lifecycle as part of the HMI system.
Architecture options
Let the workload decide the architecture class.
A focused serial or MCU interface, a richer RTOS HMI and an application-class Linux system solve different problems. The HMI Selector uses the rest of your brief to narrow the starting point.
Smart Display / Compact MCU
For focused control and status interfaces where integration effort, startup and cost matter strongly.
Performance RTOS HMI
For richer graphics, more pages and broader I/O while retaining an embedded real-time product model.
Embedded Linux HMI
For complex workflows, larger software stacks, networking, media or application-style functionality.
Reference demo
Agricultural monitoring reference demo
A real 7-inch agricultural monitoring interface provides a starting point for discussing machine data, touch workflow and platform trade-offs.
