Claim One:
1. A method for generating control signals based on contacts of a touch sensing surface, each contact having multiple degrees of freedom of an associated touch object on or near the touch sensing surface, the method comprising: obtaining tracking information of a plurality of contacts, the contacts corresponding to touch objects on or near the touch sensing surface; computing, based on the tracking information, motion information of the plurality of contacts, the motion information including a first component of motion that is one of translation motion, rotational motion, and scaling motion, and a second component of motion that is a different one of translation motion, rotational motion, and scaling motion than the first component of motion; modifying the motion information to obtain modified motion information, wherein the modifying includes downscaling the second component of motion relative to the first component of motion; and transmitting the modified motion information as a control signal of an electronic or electro-mechanical device.
