(2) Contact tracking and identification module for touch sensing , which is a method for providing input to a computing device having an associated multi touch sensitive surface, the method comprising: obtaining tracking information of a plurality of contacts, each contact corresponding to a multi touch object being tracked on or near the ouch sensitive surface,the tracking information including motion information of individual contacts within the plurality of contacts;

(3) Multi-touch contact motion extraction, which is that a method for generating control signals based on contacts of a touch sensing surface, each contact having multiple degrees of freedom of an associated multi touch object on or near the multi touch sensing surface, the method comprising: obtaining tracking information of a plurality of contacts.

I just know about these information, if you know more, you can write down.
