As a contractor, I worked at Moon Surgical as the only Product Designer to support them in redesigning the second version of the human interface on their robot.
After studying the first version of the interface and reviewing user logs and complaints, I decided to approach with a new icon focused design system which speaks for with less clutter.

CONTEXT
Surgical teams use Maestro's human-machine iterface to control the robot digitally
Surgical teams use Maestro's human-machine iterface to control the robot digitally
This case study features the redesign of the HMI to optimize robot control by surgical teams
WHY WAS A REDESIGN NEEDED?
Moon Surgical's ground support team flagged that Maestro assisted surgeries were often getting cancelled midway due to problems with robot's touch controls.
The Maestro system is a compact robot, which helps surgeons perform minimally invasive surgeries with precision.
Research revealed 3 key problems with the interface
Research revealed 3 key problems with the interface
Excessive touch targets in a linear flow
Users expected to follow a linear, three step journey to complete the robot setup, but the interface showed too many touch targets in a disorganized, often close packed fashion, causing cognitive fatigue, hesitation, and errors.
Touch Targets

Unclear Instructions
Guided instructions for setup lacked visual hierarchy and clarity, leaving users unsure of what to do next - leading to backtracking, and time consuming setup.
Instructions

Fault modals with no context
When a fault occurs, modals appear without contextual fault message or recovery option, often blocking the entire interface - forcing users to restart the system - breaking trust and disrupting critical workflows.
