Patent ID: 7062717

Claim:
A generating device comprising: means for generating signals for a graphical display in which a focus can be navigated between spaced, functional display regions such that they are individually selected when the focus is moved thereto, means for defining a plurality of spaced nodes defined based on the locations of said functional display regions, means for configuring said nodes so that the focus makes a step movement from one node to another node in response to user actuation, means for arranging the nodes in a mesh at the intersections of a first set of spaced lines extending in a first predetermined direction and a second set of spaced lines extending in a predetermined second transverse direction, the functional display regions being irregularly disposed in the display, means for disposing at least one of the nodes at each of the regions respectively, and means for defining the first and second sets of spaced lines in dependence upon positions of a given set of functional display regions and said nodes being placed at the intersections of said lines.
