CLASS LINK+ : Intelligent Online Learning Environment

Online education has become an essential part of modern learning, especially in schools and higher education institutions. While online classroom platforms provide flexibility and easy access, they face major challenges related to attendance accuracy and student participation. Most existing systems mark attendance only at login, which does not ensure that students are actively present throughout the session. This paper introduces ClassLink+, an Android-based intelligent online classroom system designed to ensure accurate attendance monitoring and active student participation. The proposed system integrates real-time video communication with AI-based attendance tracking and an inbuilt smart board for note-taking. ClassLink+ continuously verifies student presence using face or person detection techniques applied to live camera feeds, reducing the need for manual monitoring by teachers. The system architecture uses Flutter-based mobile applications for students and teachers, supported by a backend AI processing module for attendance verification. Students who remain absent from the camera view beyond a predefined threshold are automatically removed from the class, ensuring attendance reflects actual participation. The integrated smart board allows students to write notes during live sessions, which are saved and converted into PDF format. Experimental evaluation demonstrates reliable attendance detection under varying classroom conditions. The results show that ClassLink+ improves attendance accuracy, reduces instructor workload, and enhances the effectiveness of online learning.
