AI with your laptop webcam: finger counting, hand signs and faces for kids
TinkerPie Studio turns your laptop webcam into an AI sensor. Google's MediaPipe hand and face models run inside the browser, so no picture leaves the computer.
What the AI can see
- Fingers held up, both hands together: 0 to 10
- Hand signs: fist, open hand, pointing, peace, thumbs up, thumbs down, rock
- Where the hand is, and a pinch between thumb and finger
- Faces, where the face is, how close it is, and how big the smile is
- The colour in the middle of the picture, movement and brightness
How to use it
- Open an AI project, for example the finger counter.
- Press Run, then Start camera, and allow the webcam.
- Show your hand. The board in the simulator shows the number.
- On the real board: download the program and keep the USB cable connected. Studio sends what the camera sees to the board about 10 times a second.
