Design Rationale

The Smart Desk Ergonomics Real-Time Advisor is designed with a focus on user experience, accuracy, and privacy. React was chosen for its component-based architecture, allowing for a modular and maintainable codebase. TensorFlow.js enables client-side posture analysis, reducing latency and addressing privacy concerns. The Node.js backend provides scalability for handling multiple users, while MongoDB offers flexibility for storing diverse ergonomic data. The implementation plan prioritizes core functionality first, followed by enhanced features and thorough testing to ensure a robust and reliable application.
