Abstract:
A method of implementing a single input device for controlling movement of a cursor displayed on a data processing system and for controlling access of a particular piece of data within a data field displayed by the data processing system, said method comprising:positioning a moveable cursor to a location on a display screen in response to movement with said input device when a signal supplied by said input device is in a first state; when said signal is in a second state, remapping control of said input device, wherein movement with said input device controls both a resolution and a range of said data field for display on said display screen; selectively varying said resolution at which said data field is displayed responsive to movement with said input device in a first axis, wherein movement with said input device in said first axis changes said resolution; controlling said range of the data field for display in response to movement with the input device in a second axis, wherein movement in the second axis causes different ranges of the data field to be displayed; moving the input device in the first and second axes to simultaneously vary said resolution and said range of display, until the particular piece of data is accessed.
