Graphical communication device.

摘要

A portable device (8) for silent graphical communication has a display screen (10) on which a user may scribble notes and information using a stylus (14). These data are then broadcast by the device and received by other similar devices and displayed on their screens. User of the other devices can respond to the received information by scribbling their own notes on their screens and broadcasting them. The ensuing bilateral or multi-party communications may be password-protected. <IMAGE>
