ABSTRACT:
A method and system to recognize input events from a plurality of input devices. Each input device is coupled to a device driver or similar device specific code and a recognition provider. Upon attachment to the system, the recognition provider registers the known input events which the input device is capable of transmitting at the recognition subsystem. The recognition subsystem sends an identifier back to the recognition provider for each registered input event. When the recognition provider receives one or more input signals from the input device which are recognized as an input event, the provider sends the identifier to the recognition subsystem. The input event is transmitted to a process running on the system which may interpret the input event or request translation by the recognition subsystem. The invention is useful to introduce new input devices to a system without requiring modification of the existing processes.
