Data Acquisition Module: Collects raw signals from sensors in real time.

Preprocessing Module: Filters noise, corrects anomalies, and formats data consistently.

Local Analysis Module: Runs lightweight algorithms for immediate feedback (e.g., high-stress alerts).

Functionality: Provide instant readouts (e.g., detecting a student’s sudden drop in attention).

Algorithms: Classify states such as focus, distraction, or stress.

User Feedback: Prompt visual or audible alerts for teachers to intervene promptly.
