ABSTRACT:
A tool that allows a user, such as a software developer, to create test data that can consistently be employed to simulate the operation of a hardware pen or stylus. Raw pen data, such as position coordinates, pen angle and pen properties, is captured. This data is then later injected into a system being tested in place of pen data from a device driver. The raw pen data may be captured through an application programming interface invoked by a host application. The captured data can then subsequently be injected through another application programming interface invoked by a host application, such as a software testing application for testing a variety of operations of another software application. Alternately, a stand-alone utility may be used for capturing and then injecting raw pen data.
