System and method for navigation in an electronic document

摘要

A system and a method facilitating navigation in an electronic device and for enabling users of electronic devices to navigate quickly, smoothly, and naturally through electronic books and other documents using multi-touch gestures on a touch sensitive surface of the electronic device. The multi-touch gestures are movements of the multiple touches such as, preferably, a two-finger slide or flick gesture. This gesture is interpreted by the system as a command to navigate to the next or to a previous section of the electronic document, for example, the next chapter in a book or an article or section in a magazine. The device has firmware and/or software capable of analyzing and interpreting the motion, and forwarding the analyzed contents or interpretation to an appropriate software application or other software subsystem that associates the gestures with a set of commands.
