First Claim
Patent Images
1. A zooming system for a display, comprising:
- a zooming circuit, operated according to a predetermined algorithm, for zooming information in a zooming frame; and
a zooming pressure sensor, electrically coupled to said zooming circuit and capable of converting a pressure input into a physical parameter detectable by said zooming circuit;
whereina magnitude of said physical parameter is in proportion to a zoom factor of said zooming.

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.
