Method and system for handling multiple touch input on a computing device

摘要

A system for handling multi-touch input on a computing device enables the device to handle multi-touch input where each touch input is provided to a separate application executing on the device. In response to a first touch input, a first application generates and registers a first connection point with a link component. Similarly, a second application generates and registers a second connection point in response to a second touch input. The link component then provides the second connection point to the first application and notifies the first application that it should complete a communication connection with the second application. The two applications then exchange information to determine a coordinator application that will execute first in response to the input. The information exchange may include a handshake process in which each application may request or provide information and notify the other application that it will or will not execute an operation. After the coordinator is selected, the selected application executes an operation.
