Air Handwriting Detection Using OpenCV and Recognition Using CNN

This notebook contains code to detect the tip of an air-pen* in front of a camera which allows us to write in the air in a video.

Recognizing hindi letters written by tracing your hand in the air

Air writing app for Parkinson's patients that utilizes on Machine Learning and Computer Vision (CIS 4962 Senior Design Project)

Virtual AI Writer uses fingertip detection for gesture-based interactions. Features include air writing, drawing, selecting, erasing, and moving objects, as well as a virtual mouse for scrolling PDFs, webpages, and more. Powered by computer vision, it offers an intuitive hands-free experience bridging physical and virtual worlds.

Recognition of air-handwritten vowels in the air using the IMU of the STWIN module.

AI-powered virtual writing and interaction system using fingertip gestures for writing, drawing, and object manipulation.

A real-time, touchless interface that lets users write in thin air. Using a standard webcam, OpenCV, and MediaPipe, the system tracks 3D hand landmarks to generate digital ink from pinch gestures. It then applies a personalized template-matching algorithm to instantly classify and digitize multi-stroke handwriting with zero latency.
