Abstract
To allow a computer platform to provide a consistent interface for applications to use information from multi-point indirect touch input devices, an application programming interface is provided to a software interface layer that manages interaction of the system with a variety of instantiations of multi-pointer indirect touch input devices. A runtime module provides information from the indirect touch input devices to an input stack accessible by applications on the computer system. The runtime module provides mapping of contacts on the indirect touch input devices to a display.
