Challenges

1. OCR Accuracy
   Challenge: Integrating a UVC (USB Video Class) endoscopy camera with a native Android application was one of the most critical challenges. Android does not provide full native support for external UVC medical cameras, which led to issues with device recognition, connection stability, and stream handling during image and video capture.
   Solution: To overcome this, a dedicated UVC camera library was integrated into the application. Custom handling was implemented to manage USB permissions, device lifecycle, and camera initialization. Additional optimizations were applied to ensure stable streaming, reliable capture, and smooth interaction between the hardware and the Android app.
2. Medical Image and Video Quality Optimization
   Challenge: Medical diagnosis depends heavily on image and video clarity. Captured endoscopy images and videos initially faced issues such as compression artifacts, frame drops, and inconsistent quality across devices.
   Solution: Specialized media handling techniques were implemented to optimize resolution, frame rate, and compression settings. The camera library was fine-tuned to balance high-quality output with performance efficiency, ensuring that all captured images and videos met clinical review standards while maintaining smooth app performance.
3. Role-Based Dashboard Management
   Challenge: Each user role (Super Admin, Hospital Admin, Nurse, Doctor) required access to different datasets, features, and dashboards. Maintaining strict access control while keeping the UI intuitive was a significant challenge.
   Solution: A role-based access control (RBAC) system was implemented. Dashboards, actions, and data visibility were dynamically rendered based on user roles. This ensured that users only accessed authorized data while maintaining a clean and focused interface tailored to their responsibilities.
4. Role-Based Dashboard Management
   Challenge: Each user role (Super Admin, Hospital Admin, Nurse, Doctor) required access to different datasets, features, and dashboards. Maintaining strict access control while keeping the UI intuitive was a significant challenge.
   Solution: A role-based access control (RBAC) system was implemented. Dashboards, actions, and data visibility were dynamically rendered based on user roles. This ensured that users only accessed authorized data while maintaining a clean and focused interface tailored to their responsibilities.
5. Offline Support with Local Database
   Challenge: Hospitals and clinical environments may experience unstable internet connectivity, which could disrupt workflows during patient registration, case creation, or media capture.
   Solution: A local database was implemented to store patient, case, and media metadata offline. Once connectivity was restored, data automatically synchronized with Firebase, ensuring no loss of critical medical information and uninterrupted clinical operations.
6. Secure Multi-Role Communication
   Challenge: Enabling secure and instant communication between nurses, doctors, and administrators while maintaining data privacy and role boundaries was essential.
   Solution: A real-time messaging and notification system was developed with role-based filtering. Users could communicate efficiently while ensuring that messages and alerts were delivered only to authorized recipients.
