1. A user interface method for an electronic device, comprising:
- capturing a collection of coordinates that correspond to handwritten information on an input device;
recognizing a command gesture in the collection of coordinates, the command gesture identifying a set of coordinates forming at least a portion of the collection of coordinates as representing a command; and
translating the identified coordinates to the command.

Abstract
A user interface for an electronic device has a pen based input device (256) that captures a collection of coordinates that correspond to handwritten information. According to certain embodiments, a processor (260) carries out a command recognition process in which a command gesture (124, 130, 134, 138, 142, 144, 148) is recognized (210) in the collection of coordinates. The command gesture identifies a set of coordinates form at least a portion of the collection of coordinates that represent a command (120). The identified coordinates are then extracted (220) and translated to a command (230) for execution (244).
