Systems for changing orientation of displayed content

In a multiuser touch sensitive display device including an orientation module capable of providing a plurality of touch interfaces and a touch sensitive display screen capable of displaying a plurality of windows, each window providing a user interface of a running instance of an application program for receiving inputs and displaying output content of the application program instance, wherein the multiuser touch sensitive display device enables a plurality of users to provide touch sensitive inputs simultaneously through the touch sensitive display screen and wherein not all of the plurality of users are oriented in a same direction with respect to the multiuser touch sensitive display device, a method for changing an orientation of at least one of the plurality of windows without changing an orientation of the multiuser touch sensitive display device, the method comprising:

• receiving touch sensitive inputs from at least one of the plurality of touch interfaces, each touch interface associated with one of the plurality of windows for changing an orientation of the associated window, wherein each of the touch sensitive inputs is provided by one of the plurality of users using a single object for changing an orientation of the each associated window;
• and
• processing the received touch sensitive inputs at the orientation module for changing an orientation of the each associated window such that the each associated window can be oriented towards at least one of the plurality of users for viewing the each associated window at a desired orientation angle.
