Inspiration
In many classrooms, students struggle silently. Whether due to shyness, anxiety, or fear of judgment, not every learner feels comfortable raising their hand to say, “I don’t get it.” This silence can leave teachers unaware of who needs help, and students fall behind without personalized support. Our team wanted to change that. We envisioned a simple, non-verbal way for students to express their understanding—and a smart system that helps teachers respond with tailored guidance. That’s how our AI-powered Arduino tracker was born.
What it does
We built a classroom feedback system using an Arduino device with three buttons, each representing a level of understanding:
-“I understand”
“I kinda get it”
“I don’t understand”
-Students press the button after each lesson or concept. Their responses are recorded and sent to a teacher dashboard, which visualizes the class’s overall comprehension.
-Then, using AI, the system generates personalized homework assignments for each student based on their feedback—ensuring that every learner gets the right kind of support.
How we built it
Student Input via Arduino Each student uses a simple device with three labeled buttons. After a lesson, they press the one that matches their level of understanding.
-Data Collection & Syncing The Arduino sends the input to a central system that logs each student’s response by concept and timestamp.
-Teacher Dashboard Teachers view a real-time summary of class understanding—heatmaps, bar graphs, and individual breakdowns—making it easy to identify who needs help and where.
-AI-Generated Homework Based on the collected data, our AI model creates customized homework:
-Extra practice for students who are struggling
-Reinforcement for those who are unsure
-Enrichment tasks for those who fully understand
Challenges we ran into
We face problems with the software and integrating the hardware with the software but made it at the end.
Accomplishments that we're proud of
-Empowers Introverted Students: Gives every learner a voice without requiring verbal participation.
-Supports Differentiated Instruction: Teachers can meet students where they are, without manually tracking each one.
-Saves Time: Automates homework creation, freeing teachers to focus on instruction and support.
-Boosts Engagement: Students feel seen and supported, increasing motivation and confidence.
What we learned
We learnt about Flask, Huginface, Web development,
What's next for IntroBand
-To make our system even more powerful and inclusive, we plan to add:
-Real-Time Feedback During Lessons Let students press buttons mid-lesson to help teachers adjust pace or approach instantly.
-Multi-Modal Input Options Add voice, gesture, or touchscreen input for accessibility.
-Concept Tagging Track understanding at a granular level by tagging specific concepts.
-Emotion Detection Use facial expression or sentiment analysis to detect frustration or confusion.
-Gamified Homework Turn assignments into interactive, game-like experiences tailored to each student.
-Parent Portal Share progress summaries with parents to keep them informed and involved.
-Longitudinal Analytics Track student growth over time to identify patterns and long-term needs.
-Curriculum Integration Sync with school databases to align homework with standards and upcoming topics.
-Offline Mode Enable local data storage and syncing for schools with limited internet access.
-Teacher Feedback Loop Let teachers rate AI-generated homework to help the system improve.
