  • Patent number: 5694150
    Abstract: A graphical user interface system is provided having an event-driven control program with a unified user input pointing event stream without distinction of source and a graphical user interface having a virtual display space containing objects. The control program processing events related to a plurality of user inputs representing different locations within the virtual display space, and operates optionally in two modes. A first mode permits the plurality of user inputs to interact, allowing an object in the virtual display space at a first location specified by an initial user input to be associated with a second location specified by a concurrent and subsequently terminating user input. In this case, the control program has a counter which increments on activity of any user input and decrements on cessation of activity of any user input, for determining an initial user input condition, temporal concurrence of a plurality of user inputs, and a terminal user input condition.
