Embodiment Construction

[0026] Reference will now be made to the drawings in which the various elements of the invention will be given reference numerals and in which the invention will be discussed to enable those skilled in the art to make and use the invention. It is to be understood that the following description is only illustrative of the principles of the invention and should not be taken as narrowing the appended claims.

[0027] The presently preferred embodiment of the present invention is a modified capacitively sensitive touchpad capable of object detection and tracking on its surface. One such touchpad is manufactured by Cirque(R) Corporation. As explained above, capacitance sensitive touchpads can provide the functionality normally associated with touchpads. By way of example, such functionality includes (but should not be construed as limited to) cursor control. Controlling the cursor is generally considered the primary touchpad function when used with a graphical user interface. As...

Abstract

The present invention relates to rectangular sensor grid that provides functionality as a rectangular touchpad sensor and a circular scrolling region. A touchpad that provides general-purpose touchpad functionality such as cursor control controlled by movement of a pointing object on a touchpad surface, wherein a mode of operation of the touchpad can be changed such that the touchpad now provides functionality through a circular scrolling region defined as a circular region on the touchpad surface, to thereby provide improved manipulation of lists and other functions that can be provided by a circular scrolling region.

Description

[0001] For cross-references to related applications [0002] This document claims priority to all subject matter contained in Provisional Patent Application Serial No. 60 / 698,392, filed July 12, 2005, Serial No. 3339.CIRQ.PR, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention generally relates to touchpads. More specifically, a capacitively sensitive touchpad that provides cursor control and has a rectangular shape defined by electrodes forming an X-Y grid can also provide a circular scrolling area that enables circular motion on the circular scrolling area to Scroll on the list. Background technique [0004] Characterization of the State of the Art in Capacitive Sensitive Touch Pads by Cirque TM Corporation's touchpad and touchpad sensor circuitry. Cirque(R) Corporation's touchpad technology has evolved, but several elements of past and current hardware and testing methods can be used to demonstrate the inv...
