### Use Case 1: Personalized Learning and Adaptive AI Tutoring  
**Educational Challenge:** Despite recent advancements in adaptive learning technologies, existing systems often fail to deliver truly personalized instruction due to two key limitations: (1) a lack of real-time feedback loops, which inhibits timely adjustments to student engagement and comprehension signals, thus diminishing instructional quality [37]; and (2) persistent concerns regarding privacy and regulatory compliance, particularly when student data are transferred to centralized cloud services, thereby increasing data security risks in educational settings [22].  
**GEAI-Enabled Solution:** The GEAI framework introduces a conceptualized Trusted Domain infrastructure that securely integrates Multimedia Registration Devices (MM Devices), multimodal AI models, and institutionally governed data pipelines. This architecture enables real-time, privacy-preserving AI tutoring at scale, pending prototype development and pilot testing [35; 47].  
**Workflow and Capabilities:**  
* Secure Multimodal Sensing via MM Devices: MM Devices are envisioned for classroom deployment to capture rich multimodal signals, including: _Visual cues_ (**e.g., _facial expressions, gaze shifts_ via _up to 1080p video);_  
_Auditory responses (e.g., oral responsesand answers captured atup to 16 kHz audio);_  
_Behavioral metrics_ (**e.g., _posture changes, hesitation, keyboard latency)._  
These data streams are locally encrypted (AES-256) and preprocessed on-device to preserve student privacy and comply with FERPA and GDPR [35].  
* Adaptive AI Tutoring via Federated Inference: GEAI's core inference module incorporates three AI strategies (see Figure 2):  
_Federated Learning_ (**e.g., _FedAvg algorithm_**) allows local model updates on MM Devices without transmitting raw data to the cloud [47];  
_Reinforcement Learning_ dynamically adjusts the difficulty and sequencing of learning materials based on observed student states;  
_Prompt-based NLP agents_ provide real-time explanations, motivational feedback, and task scaffolding tailored to student needs [19; 28; 52]. For example, if a student shows hesitation when solving a fractions problem, the GEAI system may suggest visual analogies or simplified sub-tasks and adjust the next questions accordingly.  
* Multistakeholder Feedback and Reporting: Proposed MM Devices are also designed to deliver real-time micro-feedback to instructors (e.g., \"Pause and clarify fractions\"), enhancing situational awareness. Beyond real-time assistance, securely transmitted and audit-tracked outputs will support role-specific dashboards on the GEAI platform:  
_For students:_ personalized performance reports with progress visualizations and learning goals;  
_For teachers:_ dashboards identifying struggling learners and instructional bottlenecks;  
Figure 2: GEAI-based Framework for Personalized Learning and Adaptive AI Tutoring. The figure illustrates how MM Devices collect multimodal signals (gaze, speech, behavioral data), which are then processed through federated learning, reinforcement learning, and prompt-based NLP to generate adaptive responses for students, teachers, and parents.  
_For parents:_ weekly summaries of engagement, growth metrics, and emotional markers.  
All reports will be governed by institutional access policies and privacy safeguards, ensuring ethical deployment and regulatory compliance [22].  
**Educational Impact:** By integrating edge-based multimodal sensing with secure model inference and targeted stakeholder feedback, GEAI transforms static e-learning environments into responsive, learner-centered ecosystems. This closed-loop system enhances motivation, supports differentiated instruction, and empowers educators with actionable insights--thereby addressing both equity and quality concerns in contemporary education [22; 37].
