Abstract: A graphical user interface, i.e., multimedia communications application program, for setting up and handling a multimedia call is disclosed that employs realistic metaphors of real life face-to-meetings in setting up and handling a multimedia call to establish a virtual meeting which is automatically reconfigured in response to user action. This is realized by taking advantage of prospective virtual meeting participants' already existing knowledge of how real life face-to-face meetings operate. To this end, the multimedia communications application program enables the virtual meeting participants through direct manipulation of the realistic graphical metaphors to establish a realistic virtual meeting room which is displayed on the screen of their workstation monitor. The virtual meeting room includes a table and chairs arranged in a realistic manner in the virtual meeting room.

Abstract: An easy-to-use user interface device includes: parts forming means 13 for forming parts providing visual representations of functions of applications; parts storing means 1 for storing the information upon parts; operational environment constructing means 500 for constructing the operational environment by combining the parts together to construct operational environments; operational environment storing means 14 for storing the constructed operational environment; and operational environment using means for executing a task of an application via the operational environment read out from the operational environment storing means 14. The visual, semantic, and movement information upon the parts, representing the screen images, the associated functions, and movements thereof, etc., are stored and adjusted as the user uses the operational environment. The adjustments are effected automatically as far as feasible, thereby reducing the burden upon the user.
