Hi all,

Nokia proposes the Transform Action Event Interface to the Web Events WG for consideration.

The proposal addresses the representational level of touch interactions described in the scope of the WG charter [1].

While low-level touch events can convey the touch actions performed by the user, they do not necessarily convey the high-level intent of the user. This proposal bridges this gap by introducing three new event types to enable direct manipulation of a DOM element in response to a user interaction. As the user performs an action or gesture to request a "pan", "zoom" or "rotate" transformation to a DOM element, a series of transform action events are fired, allowing recipients of the events to perform the corresponding operations on the DOM element.

The proposed events provide web authors with an alternative to working with low-level touch events to create highly interactive web applications. Demonstrations [2] of the usage of these APIs have been developed by Thomas Fuchs, the creator of the script.aculo.us Javascript library [3].

For additional information, please also see the Nokia Starlight project [4]..

Regards, Cathy Chan.
