1. A method of input of a computing system including a touch sensing surface, the method comprising: obtaining touch sensing information of a scan of the touch sensing surface; determining, based on the touch sensing information of the scan, contact information of a set of one or more contacts, each contact corresponding to a touch object on or near the surface and the contact information including an angle of one of a major axis and a minor axis of a first contact of the set; determining, based on the angle, a first orientation of the first contact; and generating input of the computing system based on the first orientation.
