Abstract

A zooming pressure sensor is used to control the zooming of information in a zooming frame on a displayed for a cell phone, portable media device, or an electronic reader. A zooming pressure sensor converts finger pressure into corresponding physical parameter such as conductance, resistance, or charge, which is further processed by a circuit for control parameter of a zooming frame. The magnitude of output parameters is designed in positive relation to zoom-in, and in negative relation to zoom-out.
