Patent ID: 7804488

Claim:
A method of enabling input on a handheld electronic device comprising an input apparatus, an output apparatus, and a processor apparatus, the input apparatus comprising at least one switch assembly that comprises a substrate, a capacitive sensing system, and at least a first switch, the substrate having a first surface and a second surface opposite one another, the capacitive sensing system comprising a series of contacts having at least three contacts disposed on the first surface, the at least first switch being disposed on the second surface and being engageable with an engagement structure to provide an input to the processor apparatus, the output apparatus comprising a display, the method comprising: detecting as a first navigational input an input from the capacitive sensing system resulting from a sliding movement by a user in a first direction along the series of contacts on the substrate; responsive to said detecting, moving a visual focus on the display in accordance with the first navigational input; detecting as a tap input from the capacitive sensing system an input resulting from a movement by the user toward a contact at an end of the series and, responsive thereto, initiating a page-shift operation of the visual objects on the display in the first direction.
