Claim 6 of Australian Standard Patent No 2005246219, entitled “Multipoint touchscreen” (the Touch Screen Patent)

A touch panel having a transparent capacitive sensing medium configured to detect multiple touches or near touches that occur at a same time and at distinct locations in a plane of the touch panel and to produce distinct signals representative of a location of the touches on the plane of the touch panel for each of the multiple touches, the transparent capacitive sensing medium comprising:

a first layer having a plurality of lines that are electrically isolated from one another and formed from a transparent conductive material; and

a second layer spatially separated from the first layer and having a plurality of lines that are electrically isolated from one another and formed from a transparent conductive material, the second conductive lines being positioned transverse to the first conductive lines, the intersection of transverse lines being positioned at different locations in the plane of the touch panel, each of the conductive lines being operatively coupled to capacitive monitoring circuitry,

wherein the first layer and the second layer are disposed on two sides of an optically transmissive member.

Claim 1 of the Heuristics Patent

A computer-implemented method, comprising:

at a computing device with a touch screen display,

detecting one or more finger contacts with the touch screen display, applying one or more heuristics to the one or more finger contacts to determine a command for the device; and

processing the command;

wherein the one or more heuristics perform the functions of:

determining that the one or more finger contacts correspond to a one-dimensional vertical screen scrolling command rather than a two-dimensional screen translation command, based on an angle of movement of the one or more finger contacts with respect to the touch screen display; and

determining that the one or more finger contacts correspond to a two-dimensional screen translation command rather than a one-dimensional screen translation command, based on an angle of movement of the one or more finger contacts with respect to the touch screen display.

Claim 55 of the Heuristics Patent

A computer-implemented method of any one of claims 1 to 26, wherein

the one or more finger contacts correspond to a finger gesture with an initial movement and a subsequent movement, and wherein

the function of determining that the one or more finger contacts correspond to a one-dimensional vertical screen scrolling command rather than a two-dimensional screen translation command includes identifying the entire finger gesture as the one-dimensional vertical screen scrolling command and basing the determination on the angle of movement of the initial movement of the finger gesture, and wherein

the function of determining that the one or more finger contacts correspond to a two-dimensional screen translation command rather than a one-dimensional vertical screen scrolling command includes identifying the entire finger gesture as the two-dimensional screen translation command and basing the determination on the angle of movement of the initial movement of the finger gesture.
