1. A portable device for silent, graphical communication comprising:
- a screen for receiving and displaying a graphical input;
an input device, coupled to said screen, for inputting a first graphical input to said screen;
means, coupled to said input device, for converting said first graphical input to a first graphical data set;
means, coupled to said means for converting said first graphical input to a first graphical data set, for transmitting via wireless communication said first graphical data set;
means for receiving a second graphical data set, wherein said second graphical data set is broadcast from a remote location;
means, coupled to said means for receiving a second graphical data set and to said screen, for converting said second graphical data set to a second graphical input to be displayed on said screen; and
means, coupled to said means for transmitting and said means for receiving, for autonomously allocating a time period to transmit said first graphical data set and avoid data collisions.

Abstract
A portable device for silent graphical communication. The device has a display screen on which a user may scribble notes and information using a stylus. These notes, which are then broadcast by the device, are received by other similar devices and displayed on the screens of the other devices. User of the other devices can respond to the received information by scribbling their own notes. The ensuing conversations may be password protected.

18. A method for multiparty, silent graphical communication using portable devices comprising the steps of:
-
writing a message on a screen of a first portable device using an input device; representing said message within said first portable device as a graphical data set; transmitting, from said first portable device said graphical data set, via wireless communication, wherein said step of transmitting comprises the step of autonomously allocating a given time interval and a given duration of time to transmit wherein a data collision is avoided; receiving at a second portable device said graphical data set; and converting said graphical data set to said message for display on a screen of said second portable device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
