Embodiment Construction

[0038] Referring now to the drawings, in which various elements of the invention will be given numerical designations and in which the invention will be discussed to enable those skilled in the art to make and use the invention. It will be understood that the following description is only illustrative of the principles of the invention and should not be taken as limiting the appended claims.

[0039] Before describing embodiments of the present invention, it is important to understand that the touchpad hardware of the present invention scans all touchpad electrodes. CIRQUE The touchpad of ® always has the ability to collect the same raw data, as shown in the prior art of FIG. 2 . In addition, the scanning method of the electrodes of the touch panel is not an element of the invention. CIRQUE used in the present invention The company's touchpads appear to be unique in that the electrodes are grouped and scanned sequentially rather than simultaneously. However, what is rele...

Abstract

A system and method for detecting and tracking multiple objects on a touchpad or touchscreen, wherein the method provides a new data collection algorithm, wherein the method reduces a calculation burden on a processor performing detection and tracking algorithms, wherein multiple objects are treated as elements of a single object and not as separate objects, wherein the location of the objects are treated as corners of a quadrilateral outline of a single object when two objects are detected, and wherein the multiple objects are capable of being tracked so as to perform a multi-touch rotation gesture.

Description

technical field [0001] The present invention generally relates to methods of providing input to a touchpad. In particular, the present invention relates to a method of detecting and tracking a turn gesture when gesturing using multiple objects on a touch-sensitive surface in a manner that treats the multiple objects as a single object whose circumference or Endpoints are defined by the plurality of objects, whereby detection and tracking algorithms are simplified by treating the plurality of objects as a single object. Background technique [0002] As portable electronic devices become more ubiquitous, the need to effectively control them becomes increasingly important. The wide variety of portable electronic devices that benefit from the use of touch-sensitive surfaces as a means of providing input to users includes, but is not considered limited to, music players, DVD players, video file players, personal digital assistants (PDAs), digital Cameras and camcorders, mobile ...
