5.2.2.6 PHYSICAL DISPLAY

As stated before, the view is not necessarily on a physical display. To aid in the conceptual distinction between a screen-view and a display, a Display tuple is defined. A display can consist of multiple views (Vⁿ) on a single devices, a single view on multiple devices (Dⁿ), or multiple views on multiple devices. Of course, a coordinate system must be used to map the icons onto the physical displays and perform device related activities to permit the intended representation to be displayed appropriately.

(EQ 7) D = <V^{n, Dn, C_dn>}

This notion of N views on N devices is important in a virtual environment in which collaborators may wish to interact with the same object. This involves inter-process communication across networks, which shall be addressed later.
