Abstract

A system for facilitating collaborative visual expression on a portable computing device comprises a virtual workspace module constructing a virtual workspace at the portable computing device, the virtual workspace configured to host objects including one or more objects defining one or more subspaces of the virtual workspace. A synchronization module communicates with a cooperating computing device via a wireless communication link to synchronize the virtual workspace with another virtual workspace constructed at the cooperating computing device. A graphical user interface module generates a graphical user interface that presents an individual view of the virtual workspace to a user of the portable computing device and allows visual expression within the virtual workspace via a touch input device associated with the portable computing device. A touch input data processing module processes data pertaining to touch input detected by the touch input device in connection with the graphical user interface.

38. A portable computing device including the system of claim 1.

44. A system according to claim 1, further comprising an output module configured to output data pertaining to a current visual appearance of one or more content objects that a least partially overlap with at least one of the one or more objects that define one or more subspaces of the virtual workspace, to enable displaying of at least part of the content object or objects in a vicinity of the portable computing device.
