Abstract

This paper presents “Black Pearl” system which is a programmable human-computer interface by which one can control computer mouse cursor & keyboard by using movements of head or mouth or any part of body as he or she wishes. It provides a way to control computer hands free in real time frame. The system tracks the user’s movements and translates it into the movements of mouse pointer. The system is consisting of a Web-Cam & a GUI interface which is developed in visual basic. Cursor position is navigated by calculating the correlation coefficient of tracing window in image space. Size of sub-image window, speed of mouse and “dwell- time” (time to click on a particular object or icon of window) can be varied according to the user convenience. “Black Pearl” with its onscreen keyboard also provides a way to write and manipulate data by the user and hence act as an alternative for keyboard. Experimental results show that “Black Pearl” with its easy GUI can control mouse cursor efficiently and hence act as a medium for any physically challenged person who wants to interact with the computer but cannot do so due to his physical disability in controlling mouse and keyboard.
