Abstract: A method for providing a collaboration session using a designated control pen includes receiving graphical content from either a first computing device associated with a first pen tool or a second computing device associated with a second pen tool. A request can be received from the first computing device to designate the first pen tool as the control pen. In response to the request, the first pen is designated as the control pen and the second pen is disabled so long as the first pen tool retains the control pen designation. The graphical content can be modified based on the interactions made with the designated control pen at the first display area. The modified graphical content is globally displayed, which includes providing the modified graphical content to the second computing device for display at the second display area.

Abstract: A method for virtual magnetic management of graphical content can include associating the graphical content with a digital object. First attraction properties are associated with the digital object. Second attraction properties are associated with a graphical tool for managing digital objects. Attraction between the digital object and the graphical tool can be detected based on the first and second attraction properties. If the attraction is detected, the digital object and the graphical tool are displayed as attached to one another at a display area. If no attraction is detected, the digital object and the graphical tool are displayed as detached from one another.
