Navia - Underwater Drone
Software Redesign
Project Context
​
I led the end-to-end redesign of an industrial underwater drone control software at Hydromea.
The legacy system was outdated and misaligned with ongoing drone hardware development. The company planned a groundbreaking feature: an interactive mission map linking captured images to dive map elements, reducing post-processing from hours to minutes and lowering operational error.
I was the sole UX designer in a 20+ engineer team, working in parallel with hardware development under strict time and safety constraints.

Challenges
-
Safety-critical, offline software used in extreme outdoor environments
-
High complexity with multiple simultaneous drones and tools
-
Limited interface space (touchscreen, no hover, thick device frame)
-
Rapidly evolving hardware and new feature integration
-
High-stakes environment requiring fast decision-making and minimal errors
Key UX Contributions
Interactive Mission Mapping
-
Created a globally unique feature enabling pre-dive map creation and direct attachment of dive images
-
Eliminated up to 8 hours of post-dive documentation
-
Reduced errors and improved operational traceability
-
Received strong client approval and immediate partial implementation


Dive Interface Redesign
-
Docking and dual-drone status indicators
-
Step-by-step pre-dive preparation guides
-
Self-check visualizations for 1 or 2 drones
-
Underwater communication signal indicators (affected by turbidity, distance, obstacles)
-
Tool module controls (gripper, vacuum, lighting)
-
Critical status indicators with clear hierarchy for emergency situations
Field-Optimized Design
-
Touchscreen-friendly UI (no hover)
-
High-visibility, low-fatigue color system
-
Interface layout optimised for extreme conditions and physical frame constraints, as well as for office environment use
-
Designed for low cognitive load and pragmatic decision-making


Settings & Configuration
-
Independently created a settings module post-internship, including usage guides, metric system selection, and operational parameters
-
The company later requested formal permission to integrate this module




UX Process
-
Competitive benchmark and product ecosystem analysis
-
Supervisor’s doctoral research review
-
Hybrid card sorting
-
Multiple high-fidelity prototypes (Complex prototype. Visual misalignments may occur)
-
Client presentation (US Army stakeholder)
-
Iterative user testing and design refinement
-
Visual tools to communicate design rationale to engineers and ensure synchronisation with hardware development
