Abstract
A method for determining the location of a touch input in an application window on an interactive surface of a display device is described. The application window comprises a canvas configured to display at least a portion of a user interface. The method comprises the following steps. A first location of the touch input associated with a first coordinate space is determined. The first coordinate space is associated with the interactive surface. The touch input is used to emulate a mouse event. A second location of the touch input associated with a second coordinate space is determined in response to the emulated mouse event. The second coordinate space is associated with the user interface. At least one offset parameter is calculated, correlating the first coordinate space with the second coordinate space. While the first coordinate space does not change with respect the second coordinate space, the at least one offset parameter is used to determine the location of subsequent touch inputs based on corresponding locations associated with the first coordinate space. A computer readable medium and an interactive input system for implementing the method are also described.
