Abstract: Virtual Air Board is a webcam-based system that allows users to write in the air using finger movements, without the need for styluses or special hardware. It uses computer vision to track the hand and draw on a virtual canvas, while integrated OCR converts handwriting into editable text. Simple hand gestures are also used for commands like backspace and cursor movement, making digital writing more accessible and intuitive. The system runs in real time using only a standard laptop webcam, making it highly portable and cost-effective. It eliminates the dependency on external writing tools, promoting accessibility for a wide range of users. The interface supports a natural writing experience with smooth stroke rendering and gesture feedback. This project demonstrates the potential of vision-based input systems for creative and practical applications.
