The touch screen cover includes a protective panel, that in a shielding configuration, overlays a majority of the touch-sensing user interface of the hand-held wireless communication device. The protective panel has a touch-communicating portion that overlays at least part of the swipe-sensing user control zone of the user interface of the hand-held wireless communication device in the shielding configuration, the touch-communicating portion configured to receive a swiping touch engagement on an exposed outer surface thereof and responsively impart a sweeping capacitance-induced user actuation of the swipe-sensing user control zone. ## Claims ### Claim 1 A touch screen cover for a hand-held wireless communication device having a touch-sensing user interface and a telephone operational mode, in which, during an incoming call, a swipe-sensing user control zone of the user interface is activated together with a call-information display, the touch screen cover comprising: a protective panel, that in a shielding configuration overlays a majority of the touch-sensing user interface of the hand-held wireless communication device, the protective panel having a capacitance insulative portion that does not induce capacitance in the user interface when touched by a user, and a window that overlays at least part of the call-information display, the protective panel comprises a touch-communicating portion that overlays at least part of the swipe-sensing user control zone of the user interface of the hand-held wireless communication device in the shielding configuration, the touch-communicating portion configured to receive a swiping touch engagement on an exposed outer surface thereof and responsively impart a sweeping capacitance-induced user actuation of the swipe-sensing user control zone, wherein the touch-communicating portion comprises a series of capacitance conductive portions each separated a distance one from the other, wherein

screen cover according to claim 1, wherein the series of capacitance conductive portions are each separated from one another by capacitance insulative portions that do not induce capacitance in the user interface when touched by a user. ### Claim 11 (depends on 1) The touch screen cover according to claim 1, wherein the series of capacitance conductive portions are each separated from one another by portions which register only localized capacitance at the particular localized area of engagement by the user's finger. ### Claim 12 (depends on 1) The touch screen cover recited in claim 1, wherein the series of capacitance conductive portions are each spaced apart from one another by from 0.1 to 15 millimeters. ### Claim 13 (depends on 1) The touch screen cover recited in claim 1, wherein a substantial entirety of the protective panel besides the touch-communicating portion and window is capacitance insulative. ### Claim 14 (depends on 1) The touch screen cover recited in claim 1, wherein a majority of the protective panel is capacitance insulative that does not induce capacitance in the user interface when touched by a user. ### Claim 15 (depends on 1) The touch screen cover recited in claim 1, further comprising a coupler that pivotally connects the touch screen cover to the hand-held wireless communication device. ### Claim 16 (depends on 1) The touch screen cover recited in claim 1, further comprising a flexible coupler that connects the touch screen to the hand-held wireless communication device thereby permitting the touch screen cover to swing between the shielding configuration and an open configuration. ### Claim 17 (depends on 1) The touch screen cover recited in claim 1, wherein the each of capacitance conductive portions are at least partially overlain by a capacitance insulative portion. ### Claim 18 (depends on 17) The touch screen cover recited in claim 17, wherein each one of the series of capacitance conductive zones comprises a cutout
