The challenge

Embedded GUIs on industrial machines are used under time pressure, often standing, often with gloves, and by operators with very different levels of training. Interfaces built feature-by-feature over years become dense and inconsistent.

Our scope

Our work covered research with the people who operate these machines, identifying where the current experience creates friction, and exploring new interface directions grounded in those findings.

Research

Starting from the operator's reality.

We studied how operators move through their daily tasks on the device, where they hesitate, and what they rely on memory or workarounds for. These observations became the foundation for every design decision.

Innovation

Clear, glanceable, and consistent.

We explored interface concepts that prioritise the current task, surface machine status at a glance, and apply one consistent visual and interaction language across workflows.

Key solutions

What we delivered.

  1. /01

    Operator-centred research

    Field observation and task analysis to understand real usage on the hardware.

  2. /02

    Task-first information hierarchy

    Screens organised around what the operator needs to do now, not around system structure.

  3. /03

    Consistent embedded design language

    Reusable patterns that keep the experience predictable across devices and workflows.
