Apple seeks patent on resolution independent user interface

Apple locking-up new interface design ...

"Apple Computer is looking to secure exclusive rights to techniques required to produce resolution independent user interfaces, one of the supported features of its forthcoming Mac OS X Leopard operating system.

The Cupertino, Calif.-based Mac maker described several approaches to the technique in a July 21, 2006 filing with the United States Patent and Trademark Office titled "Resolution Independent User Interface Design", which was first published on Thursday.

Essentially, the technology breaks the software assumption that all display output is to be rendered at 72 dots per inch (DPI), allowing an operating system like Mac OS X to draw or represent user interface elements using a scale factor.

"The invention provides a method to represent a graphical user interface object's material map in a procedural and, therefore, resolution independent manner," Apple wrote in the filing. "The method includes receiving values for each of a plurality of attributes associated with a material map object, associating a value for each of the plurality of attributes, and storing the plurality of attributes and their associated values in a file."    (Continued via AppleInsider)    [Usability Resources]
