Abstract: A computer generated 3-dimensional map display includes a reference icon identifying an observation point in the geographic area defined by the map, the map being presented on a curved surface which extends from a first plane to a second plane which is substantially orthogonal to the first plane. The observation point is located in the first plane. The display is configured such that the height of landmarks and buildings in a defined foreground of the reference icon are presented normal to the first plane, the height of land marks and buildings at a defined far distance are presented normal to the second plane and the height of land marks and buildings in a defined middle ground are presented normal to the non-linear portion of the curved surface. The geographic area represented can be translated along the curved surface to provide a perception that the reference icon is roaming through the displayed geographic area.

Abstract: A device for providing a representation of the presence state of a remote party, the device being responsive, when the presence state of a remote party changes, to move from a first mechanical configuration to a second mechanical configuration, the device preferably comprising a puppet portion in the form of a humanoid which can be moved between a standing and another position.
