METHOD AND APPARATUS OF PHYSICALLY MOVING A PORTABLE UNIT TO VIEW AN IMAGE OF A STATIONARY MAP
First Claim
1. A method of moving a portable unit to search for a new location comprising the steps of:
- displaying an image on a screen of the portable unit matched and superimposed to a corresponding portion of a background image of a stationary map;
mapping a first point of the display image located in a center of the screen of the portable unit to a corresponding reference point in the background image of the stationary map;
moving the portable unit to display a new portion of the background image of the stationary map on the screen;
identifying a new location in the new portion of the background image;
determining a first vector between the center of the screen of the portable unit and the new location; and
moving the center of the screen of the portable unit to the new location as determined by the first vector.

Abstract
A background map remains stationary while a portable unit moves within a plane parallel to the screen of the portable unit. As the user moves the unit, images of the background map appear on the screen of the portable device. The user scans the stationary map presented on the screen of the portable unit. This has several benefits since now relative distances and angular displacements within the plane between objects that are outside of the range of the screen of the handheld unit can be immediately be located and placed into view on the screen of a portable unit. The handheld unit is like a Sliding Window which provides a view of this image of a stationary map lying in the background of the portable unit.

9. A method of moving a portable unit to return to a reference point after searching for a new location comprising the steps of:
-
placing the portable unit at a comfortable distance from a face of a user; displaying an image on a screen of the portable unit matched and superimposed to a corresponding portion of a background image of a stationary map; mapping a center of the display screen of the portable unit to the reference point in the background image of the stationary map; moving the portable unit to search for at least one new location in the stationary map; identifying a first new location once the first new location is displayed on the display screen; moving the portable unit to place the first new location in the center of the display screen; determining the vector between the new location and the reference point; and moving the center of the screen of the portable unit to the reference point as determined by the vector. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of moving a portable unit to find a new location, to search for other locations, and to return back to the new location comprising the steps of:
-
displaying an image on a screen of the portable unit matched and superimposed to a corresponding portion of a background image of a stationary map; mapping an origin of the background image of the stationary map to a corresponding first point of the display image located in a center of the screen of the portable unit; moving the portable unit to display a new portion of the background image of the stationary map on the screen; determining a vector displacement from the origin to the new location; searching for a second new location; finding the second new location; remembering the vector displacement of the new location that was previously viewed in reference to the origin; moving the center of the screen of the portable unit to the position corresponding to the vector displacement to display the new location in the center of the screen of the portable unit. - View Dependent Claims (17, 18, 19, 20, 21)
