Abstract
The present invention provides a unique system and method that facilitates navigating smoothly and gracefully through any type of content viewable on portable devices such as cell-phones, PDAs, and/or any other hybrids thereof. In addition, such navigation can be performed while preserving perspective and context with respect to a larger amount of content. Pointing devices can also be used to navigate through content—the amount or detail of the content being dependant on the speed of the pointing device. Additionally, a semi-transparent overview of content can be overlaid a zoomed-in portion of content to provide perspective to the zoomed in portion. Content shown in the semi-transparent overview can depend on the location of the pointing device with respect to the content.

21. A system for rendering a navigation display at a mobile device, comprising:
-
a memory having stored thereon navigation data; and a processor that executes code to render the navigation data, wherein movement is represented through the rendered navigation data as a function of increasing level of detail of a subset of the navigation data as a function of velocity of the movement, and the subset of navigation data is selected as a function of user interest to create an appearance of a lens over the subset of the rendered navigation data. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method of rendering a navigation display on a mobile device screen, comprising:
-
identifying navigation display content; identifying movement of an area of interest associated with the navigation display content; rendering a first portion of the navigation display content that surrounds the area of interest at a first magnification level applied as a function of speed of the movement; and rendering a second portion of the navigation display content located outside the first portion of the navigation display content at a second magnification level to create an appearance of a lens overlying the first portion of the navigation display content. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A method of displaying content on a portable device screen, comprising:
-
identifying data to be displayed on the portable device screen; displaying the identified data on the portable device screen; detecting movement of a stylus across the portable device screen; continuously monitoring velocity of the detected movement; and zooming displayed data on the portable device screen located within a radius of the stylus, wherein size of the radius and an extent to which displayed data located within the radius are zoomed are continuously adjusted as a function of the velocity of the detected movement.
