Abstract: In accordance with the present invention there is provided a method for serverless calendar sharing that allows free/busy time to be exchanged, viewed and new appointments scheduled between computing devices sharing a common calendar format without the use of a server and using a peer-to-peer network. An interval for the meeting/appointment is selected by an initiating device, and a request is sent out to participant devices in the peer-to-peer network for a set of free and busy time slots. A time slot for a meeting is considered free if it is correspondingly free in all participating responses, otherwise it is busy. The aggregate busy time is resolved using an efficient algorithm that is easily computed on low-compute-power devices such as handhelds.

Abstract: A graphical user interface for the collaboration of participants is disclosed. The participants are located within an area and the graphical user interface is generated on a display of an electronic device. The graphical user interface comprises an area representation and at least one participant representation generated on the display. The participant representation allows a viewer of the display to quickly identify the participants in the area, as well as see information about each one. Furthermore, the graphical user interface may include information representations which allow a viewer to access information associated therewith.
