The multimodal emotion recognition framework was trained and validated only on binary emotion classification, which oversimplifies emotional representation. Future research must extend the LSTM-based architecture to multi-class emotion recognition (e.g., joy, sadness, anger, fear, surprise, neutral) or dimensional emotion models (valence-arousal) to capture finer-grained emotional distinctions that better reflect real-world emotional complexity.

The paper mentions emotion recognition and fatigue monitoring as future enhancements but does not specify which machine learning models (e.g., CNN architectures, facial action units) or datasets will be integrated into the current keyboard/mouse activity-based classifier to enable multimodal emotion-fatigue detection.
