1. An electronic reader comprising:
- a first panel comprising a first display screen for displaying a page of a document;
a second panel comprising a second display screen for displaying another page of the document, the second panel being connected with the first panel, whereby the first panel is pivotable, relative to the first panel, from a first position in which the display screens are facing to a second position in which the display screens are angled, relative to each other;
a tilt detection system comprising at least one sensor which detects tilting of the electronic reader; and
a navigation system which alternately loads fresh pages of the document onto the first and second screens in response to detected tilting.

Abstract
A dual screen electronic reader and method for navigating a document are disclosed. The electronic reader includes two display screens which can be angled to each other, like an open book, for viewing by a person reading the document. The electronic reader includes a tilt detection system for detecting tilting of the electronic reader indicative that the reader has completed reading the page on the first screen and has pivoted the electronic reader to view the opposite screen. This causes the electronic reader to load a fresh page on the first screen, optionally after a short time delay, which allows for counter-rotational tilting to be taken into consideration.

14. A method for navigating an electronic reader comprising:
-
displaying a page of a document on a first display screen of an electronic reader; displaying another page of the document on a second display screen of the electronic reader, the second display screen being angled to the first screen at an angle of less than 180°
;automatically detecting tilting of the electronic reader about an axis substantially parallel to the spine; and in response to the detected tilting, loading a fresh page of the document onto one of the first and second screens, whereby pages are loaded alternately onto the first and second screens. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A dual screen electronic reader comprising:
-
first and second panels bound to each other at a spine, the first and second panels each including a display screen, the panels and the spine cooperating to prevent the display screens from being angled to each other at greater than a fixed angle of less than 180°
;a sensor which detects tilting of the electronic reader relative to at least one reference plane; and a navigation system which is configured to automatically load a fresh page of a document onto the first screen after a first delay period following a first detected tilting and load another fresh page of the document onto the second screen after a second delay period following a second, opposite tilting. - View Dependent Claims (22)
