Abstract:
1. A method for providing input to a computing device having an associated touch sensitive surface, the method comprising: obtaining tracking information of a plurality of contacts, each contact corresponding to a touch object being tracked on or near the touch sensitive surface, the tracking information including motion information of individual contacts within the plurality of contacts; determining a translation motion of the plurality of contacts, the translation motion being based on the motion information of each contact in a first set of one or more contacts of the plurality of contacts; generating a translation input of the computing device based on the translation motion of the plurality of contacts; and generating a scaling input of the computing device based on the motion information of each contact of a second set of one or more contacts of the plurality of contacts, wherein at least a portion of the generating of the translation input is concurrent with at least a portion of the generating of the scaling input.
