Abstract
An advanced user interface operates in an integrated operating environment which supports realtime handwriting, graphical and image data. The integrated operating environment is capable of running several application programs on a standard stand-alone processor, such as a personal computer, each in its own display window. A communication window is established in a first window. Image data is imported into it from a second window. And freehand drawing data is added to the first window. The contents of the first window can then be sent to a second processor. In this manner, hand drawn images can be combined with other image data and communicated over a network.
