Hi, WebAPI WG- Many tablet devices, including graphics peripherals and tablet-laptops, have varying levels of sensitivity which measure not only the position of the pen on the canvas, but also how hard it is being pressed. This would be an easy thing for us to add, I think. I propose that we add an attribute parameter on all pointer events, something like: pressure of type unsigned float, readonly The degree of pressure that is being applied to the pointer device, measured as a multiplier of the default value "1". (I don't really mind about the name, the value type, or the spec wording, just about the functionality.) I also propose that I investigate how pen-tablets currently handle this sensitivity internally (by liasing with manufacturers), to find out if there is a more optimal solution and if they have other feedback. I further propose that I take this issue up with the SVG WG (as a likely user of this event) to see how this might be applied (e.g. determining the stroke-width on drawing webapps), and what other considerations might be needed. Thoughts? Regards- Doug
