I've looked everywhere for how to capture touch pad input for laptops but I can't seem to find anything for Chrome extensions/JavaScript.

Question: how can I capture the number of fingers down (not clicked, just down and potentially moving as you would with a mouse), their corresponding x,y coordinates, and their corresponding up events, for a touch pad on a laptop?

Clarifications:

• I'm not interested in detecting touch screen events. Just touch pad events.
• Can assume the touch pad lives on 3 year old or newer lap tops.

解决方案

to develop such kind of extension, you need to write chrome native client with Windows Touch Input to make it happen.
