Systems and methods for processing simultaneously received user inputs

In a multiuser touch sensitive display device including a touch sensitive display screen capable of displaying a plurality of windows for interacting with a plurality of users simultaneously, each window providing a user interface for a running instance of an application program run by one of the plurality of users for receiving touch sensitive inputs and displaying content output of the application program instance, and a plurality of output ports that can be coupled to a plurality of peripheral devices including audio output devices for generating audio outputs, wherein the multiuser touch sensitive display device runs an operating system module that can simultaneously interact with a plurality of instances of one or more application programs, a method for processing simultaneously received user inputs through the plurality of windows displayed on the touch sensitive display screen, the method comprising:

• simultaneously receiving at the operating system module user inputs generated by a plurality of users from a plurality of windows displayed on the touch sensitive display screen, wherein the multiuser touch sensitive display device runs a plurality of application program instances, each application program instance having at least one of the plurality of windows for interacting with one of the plurality of users, and wherein each of the plurality of users owns at least one of the plurality of application program instances;
• identifying at the operating system module for each of the user inputs a corresponding application program instance of the plurality of application program instances that is intended for the each user input to send the each user input to the corresponding application program instance;
• and
• receiving at the operating system module outputs that are generated based on the user inputs from the corresponding application program instances, wherein the outputs include a plurality of audio outputs and a plurality of visual outputs;
• identifying at the operating system module for each of the plurality of visual outputs a corresponding window to display the each visual output on the corresponding window on the touch sensitive display screen;
• and
• Identifying at the operating system module for each of the plurality of outputs a corresponding output port of the plurality of output ports that is associated with the corresponding application program instance to cause an audio device connected to the corresponding output port to generate the each audio output.
