Interactive Game Interface for Hospital Managers: 2x Faster Decision-Making

Outcome

By collaborating with Hymux Technologies, the customer received a redesigned and modernized front-end for their existing multiplayer web game. The updated interface makes the game more engaging and easier to use, while preserving all existing business logic. Subtle animations and improved visual hierarchy help players better understand their decisions and their impact on hospital efficiency.

The solution is now ready for public release outside the university network, allowing the customer to scale the project and potentially offer it to external organizations.

Customer

The customer is the ZHAW Digital Health Lab, a virtual, interdepartmental organization within the Zurich University of Applied Sciences that connects experts across different fields. Their IT department developed Save Our Children’s Hospital, a web-based game for hospital managers and medical staff. The game is designed to teach system-level thinking and help participants move away from siloed decision-making. 

Each player takes on the role of a hospital ward manager. Their goal is to improve three key performance indicators: cost efficiency, quality of care, and staff satisfaction. Players interact with each other by sharing staff, redistributing patients, and coordinating decisions across departments.

Solution

The Hymux Technologies team joined the project at the stage where the game was already fully developed and actively used inside the university network. Our task was to completely redesign and rebuild the front-end while maintaining full compatibility with the existing back-end. The team deployed the back-end locally to understand how the system worked and safely connect the new interface without affecting game mechanics.

We updated the visual design by improving layout, typography, color palette, and icons. The interface kept its original structure, but became clearer and more visually balanced.

To make the experience more engaging, we introduced lightweight animations that visually represent patient flow throughout the day. These include:

• Patient arrivals – either arriving “from the street” via ambulance or being transferred from other departments as part of player interactions.
• Bed allocation – patients moving to available hospital beds within the ward.
• Waiting room placement – patients being sent to a waiting area if no beds are available.

All animations were carefully designed to support usability and understanding of the system rather than distract players with data-heavy screens, with the goal of helping players see the consequences of their decisions in real time.

The UX and UI design process was done in English for clarity and efficiency. After approval, the interface was translated and adapted into German in close collaboration with the customer, who validated all terminology and labels.

Challenges

During the project, the Hymux Technologies team worked under several technical and organizational constraints that influenced design and development decisions:

• Back-end limitations: The back-end was a closed system that could not be modified. All front-end logic had to strictly match existing back-end behavior.
• Limited access: The game originally ran inside a university network, so the team could not access a live environment and had to work with a locally deployed back-end archive.
• Animation constraints: The game functioned as a data-heavy dashboard, leaving limited room for animations that felt appropriate and useful.
• Budget restrictions: The customer expected visual improvements without major structural changes or extensive rework.

Despite these challenges, the team successfully delivered the project on time and within budget, meeting the customer’s expectations.
