Abstract:
1. A computer mouse comprising: an arcuate cover comprising a plurality of projections on a top surface; a capacitance trigger assembly aligned with the projections thereabove and comprising a flexible arcuate first capacitive film and a flexible arcuate second capacitive film therebelow; a printed circuit board disposed under the capacitance trigger assembly and comprising photodetector means on an underside and a microprocessor; and a base releasably secured to the cover and comprising light guide means, wherein in response to a touch of the projection, a button clicking action is triggered; wherein the projections have a plurality of oblique lines or curves to form a guiding pattern; and wherein the first capacitive film comprises a plurality of rows of a plurality of first sensors and the second capacitive film comprises a plurality of rows of a plurality of second sensors, wherein the second sensors are aligned with the first upper sensors which are aligned with the projections, and wherein in response to touching the projection, a capacitance of the capacitance trigger assembly is changed to trigger the button clicking action.
