- Tracker page desktop version -
Users in the field often needed to perform urgent actions remotely,
but all tasks required desktop access or support intervention.
This created:
Slow response times
Heavy support load
Poor field usability
Friction in operational workflows

Support uses desktop

Product Goals:
Enable field teams from mobile
Reduce support dependency
Create a modern foundation for
future products
Early Exploration: Exploring what mobile operations should feel like
We explored multiple concepts for:
Dashboard summaries
Tracker lists
Alerts
Operational status views
Direct control flows
The challenge was balancing technical complexity with speed and clarity.

Design Principles: Designing trust in industrial environments
We intentionally moved away from legacy enterprise interfaces
and created a cleaner, calmer experience focused on:
Fast scanning
Operational confidence
Clear status visibility
Reduced cognitive load
Practical for operators

Key UX Decision: From technical control to intuitive control
Instead of forcing users to manually enter tracker angles, we designed a visual control model that represented the tracker physically. Users could quickly adjust direction with confidence, even in field conditions.
Based on user interviews, we learned that operators wanted more than just data, they needed to feel the tracker’s position. Feedback indicated a strong interest in visualizing the specific angle and the shadow cast by the panels.
We shifted from abstract input fields to a tactile visual model.
This increased the user's sense of control and confidence, allowing them to adjust the hardware with an interface that mirrors the physical reality in the field.
