Finger Counter Using Webcam
The Project
Finger Counter Using Webcam is a Scratch project that uses machine learning and a webcam to recognize how many fingers you're holding up. When you show your hand to the camera, the program detects the number of fingers and displays a message like “You showed 3 fingers” or “You showed 5 fingers.” It’s a fun and interactive way to explore hand gesture recognition while learning about AI. We were inspired by how gesture recognition is used in modern technology—from touchless controls to sign language interpretation. We wanted to create a simple version that combines learning and play, showing how computers can understand human gestures in real time. The most challenging part was training the model to accurately recognize different finger counts. Every hand is a little different, and things like lighting, angles, and background made it tricky. We had to collect lots of examples and do careful testing to make sure the program could recognize the correct number reliably.
