DURATION

Jul' 24 - Sep' 24

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

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

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.

Faults

To solve these problems, I followed three key design principles for the redesign.

Emphasis on icons

The new design system focused more on icon based targets, avoiding excessive use of text. This helped in maintaining clear visual hierarchy, balance, white space, and linear understanding.

Prioritize Fault Handling

Key changes were to display faults with clear labels and contextual visuals, so that surgical teams can understand what went wrong and recover without having to restart the system.

Movement Guidance

Our goal was to meet where users expect. That is to follow a simple, linear flow and provide guidance where it's necessary, without overwhelming them with instructions.

I followed the atomic design methodology to create the design system, keeping in mind the established design principles

We ideated three distinct concepts: Email templates, PDF reports, or an interactive dashboard

Interviewing users, analyzing competition and realizing the dynamic KPI requirements, we proceeded with an interactive dashboard.

We aligned with the team to prioritize the KPIs that are feasible, impactful, and worth building for users

This alignment lead to the conceptualization of the Dashboard.

After brainstorming design ideas, I created an outline of the system architecture for the Dashboard

This was followed by creating wireframes to test them with our trusted partners

After concept validation, we needed a high fidelity lift to test further and move forward

Once the mockups were ready, this is what they looked like

For refinement, I interviewed 11 surgeons and had them give us a score across 3 categories

“This feels more like something for data enthusiasts. I don’t see myself using it regularly.”

“I don’t have time to scan graphs or numbers, just tell me what I need to know.”

“Looks better than MyIntuitive for sure, but it’s the same kind of data - and I don’t really use that either.”

It was clear from the results that surgeons needed something more than just data, they needed insights

I presented the findings to our stakeholders, which helped us pivot to an AI focused insights platform

Our realignment introduced LLM based insights and a vibrant design system

This move led to the creation of Phase 1.0 of Maestro Insights

We launched the product in Dec'24 and gauged the impact until Mar'25

Go Back To Case Study

HERE ARE MY TAKEAWAYS

Product Development is rarely linear.

Research helped me re-question assumptions and reframe success around real-world value.

Real-world testing shaped real-world priorities.

Contextual testing helped us prioritize what truly mattered in the OR.

Adoption is emotional, not just functional.

I learned that trust is earned when tools feel intuitive, not imposed.

FOR HOSPITAL ADMINISTRATORS

Admin Dashboard

Hospital administrators can track a site's robot performance in the form of metrics such as Top Service Lines, Surgeons, and live robot status.

“I would like to see how the robot is used in order to justify the return on investment”

OR Traffic Control

This space serves as the live robot status and schedule for the administrators to track. They can even track robotic cases in real time.

“I would need a clear picture of how Maestro is used throughout the day.”

Trend Cards

Trend Cards are located on the dashboard page for surgeons. It helps surgeons make sense of critical KPIs at a glance.

“If something shifted, I’d like to know up front, just the key signals.”

Distribution Chart

Also on surgeon dashboard, distribution charts help surgeons track their procedure targets over time, in an interactive way.

“If I can see how I’ve used the robot over time, I can better understand the value it’s adding”

Recent Cases

Recent cases allow a surgeon to keep track of their latest cases and track their case time, notes, as well as detailed AI analysis.

“I like to check what I did recently, my cases, timing, and if anything needs my attention?”
