ABSTRACT:
An electronic whiteboard is coupled to a computer which receives information from the whiteboard indicative of graphical user inputs entered via a writing region of the whiteboard and control inputs entered via a control region of the whiteboard. A driver executing on the computer receives the information transmitted by the whiteboard, performs certain actions on the received information and causes an application program to retrieve the information and store the information to a session file. The application provides a user interface which allows a user to view images generated on the whiteboard, store such images, view previously stored images and to manipulate the images in a variety of ways.
