Beyond the Touch: A Web Camera Based Virtual Keyboard

This paper presents the concept of web camera based virtual keyboard. In order to achieve full functionality of the proposed concept digital image processing methods are being used, such as binarization, morphological operation and filtering. Real time image acquisition is performed by a mid-range quality web camera in order to test the sturdiness of algorithm design. The objective of this research paper is to identify the method of simultaneous fingertip and keyboard character recognition in order to produce a fully functional keyboard for user input.
