Touch-screen user interface

A dedicated electronic book reader device, comprising:

• a processor;
• a memory accessible by the processor;
• a touch-screen display to present a visible representation of an electronic document, the touch-screen display having a pressure detector to sense pressure applied to the touch-screen display and configured to detect specific locations of pressure being applied;
• and
• a page turn detector to turn one or more pages in the electronic document in response to sensing of pressure on the touch-screen display, wherein:
• a number of pages to turn is determined based on a number of detected locations of pressure;
• and
• the number of pages to turn increases with an increasing number of detected locations of pressure.

An electronic device, comprising:

• a touch-screen display for presenting visible representations of electronic documents;
• a processor;
• a memory accessible by the processor;
• and
• one or more programs stored in the memory and configured to be executed by the processor, the one or more programs including instructions for:
• displaying a first page of an electronic document on the touch-screen display;
• detecting a pressure of an object on the touch-screen display;
• turning one or more pages of the electronic document in response to sensing of pressure on the touch-screen display, wherein a number of pages to turn at one time is proportional to the pressure;
• and
• displaying a second page of the electronic document.

A non-transitory computer-readable storage medium having stored therein instructions, which when executed by an electronic device, cause the electronic device to generate a user interface comprising:

• visible representations of an electronic document presented on a touch-screen display;
• a force sensing arrangement for producing one or more input signals when a force is exerted on the touch-screen display by an object;
• a first area of the touch-screen display for turning pages of the electronic document forward in proportion to the force, wherein a number of pages to turn forward at one time increases in proportion to the force exerted on the first area;
• and
• a second area of the touch-screen display for turning pages of the electronic document backward in proportion to the force, wherein a number of pages to turn backward at one time increases in proportion to the force exerted on the second area.
