Submission request to W3C
We, W3C Member
hereby submit to the Consortium the following specification, comprising the following document attached hereto:
which collectively are referred to as "the Submission". We request the Submission be known as the Pointer Events Submission.
Today, most web content is used with and/or designed for mouse input. Those that handle input in a custom manner typically code to DOM Level 3 Mouse Events. Newer computing devices today, however, incorporate other forms of input, like touchscreens or pen input. Event types have been proposed for handling each of these forms of input individually. However, that approach requires a step function in opportunity cost to authors when adding support for a new input type. This often creates a compatibility problem when content is written with only one device type in mind. Additionally, for compatibility with existing mouse-based content, most user agents fire Mouse Events for all input types. This makes it ambiguous whether a Mouse Event represents an actual mouse device or is being produced from another input type for compatibility, which makes it hard to code to both device types simultaneously.
To reduce the cost of coding to multiple input types and also to help with the above described ambiguity with Mouse Events, the Pointer Events specifications defines a more abstract form of input, called a pointer. A pointer can be any point of contact on the screen made by a mouse cursor, pen, touch (including multi-touch), or other pointing input device. This model makes it easy to write sites and applications that work well no matter what hardware the user has.

The organization I represent on the W3C Advisory Committee agrees to offer licenses according to the W3C Royalty-Free licensing requirements described in section 5 of the 5 February 2004 W3C Patent Policy for any portion of the Submission that is subsequently incorporated in a W3C Recommendation.
We suggest that the Consortium start a Working Group whose mission is to produce a W3C Recommendation for Pointer Events by refining the Submission, addressing implementation experience and interoperability feedback from the Submission.
To help with this work, we expect to be able to provide assistance as needed to the Consortium.
