By placing a Jetson Nano with a camera in front of the classroom, you’ll be able to monitor your classroom with a web dashboard.
The program on Jetson Nano will take a shot periodically, do face recognition with a pretrained Tensorflow model on Jeson Nano & emotion recognition with AWS Rekognition, and record the result to Amazon DynamoDB. The webapp hosted on Amazon EC2 will then pick up the new data and update the dashboard. From the dashboard, you’ll know how many students have come to your class, and the general vibe of the classroom. With the positivity vs. time graph, you’ll even know if your joke works!
