Remarks

Describes the capabilities of a particular input device.

Each input device may support multiple classes of input. For example, a multi-function keyboard may compose the capabilities of a standard keyboard together with a track pad mouse or other pointing device.

Some input devices present multiple distinguishable sources of input. Applications can query the framework about the characteristics of each distinct source.

As a further wrinkle, different kinds of input sources uses different coordinate systems to describe motion events. Refer to the comments on the input source constants for the appropriate interpretation.
