Multiuser/multi pointing device graphical user interface system

摘要: A graphical user interface system is provided having an event-driven control program with a unified input pointing event stream without distinction of source and virtual display space containing objects. The processing events related to plurality inputs representing different locations within the space, operates optionally in two modes. first mode permits interact, allowing object at location specified by initial be associated second concurrent subsequently terminating input. In this case, has counter which increments on activity any decrements cessation input, for determining condition, temporal concurrence inputs, terminal condition. processes series apparent functional interference
