NasogastriX
An interactive radiology education app combining teaching modules and mini-games to help learners assess nasogastric tube positioning on chest X-rays.
- Unity
- C#
- Machine Learning
- Computer Vision
- Grad-CAM
- Role
- Developed the Unity and C# application, gameplay systems, and UI; integrated the supplied AI classification and Grad-CAM workflow; and handled releases and ongoing maintenance.
- Team
- Developed in collaboration with a CUHK research team
The challenge
The project combines radiology teaching content with interactive exercises that help learners assess nasogastric tube positioning on chest X-rays.
The application also needed to integrate a supplied classification and Grad-CAM workflow without obscuring the distinction between the learning experience and the underlying AI output.
Key decisions
01
Combine instruction with interaction
Teaching modules and mini-games are presented within one application so learners can move between explanation and active assessment.
02
Build on Unity gameplay systems
Unity and C# provide the application, interface, and gameplay foundation for the educational experience.
03
Keep the AI integration boundary explicit
The application integrates the supplied classification and Grad-CAM workflow as part of the learning experience without claiming ownership of model development.
Implementation
Interactive learning application
The Unity application brings together teaching modules, mini-games, gameplay systems, and the user interface in a single C# codebase.
The interaction design supports repeated assessment within the educational flow while keeping the medical content supplied by collaborators central to the experience.
AI workflow integration
The supplied classification and Grad-CAM workflow is integrated into the application so its output can be presented as part of the radiology learning experience.
Release handling and ongoing maintenance are part of the documented project contribution.
