Abstract
Abstract The present invention tunes, or focuses, an input device's effective targeting capability to the task at hand in a computer system. If there are only 5 choices selectable by a user on a given active screen area on the computer's display device, the present invention logically constrains the input device's cursor movement is to only those five positions, no matter what pixel-by-pixel movement is actually being generated by the movement of the input device. The currently displayed area and its selectable subcomponents (e.g., radio buttons) at any given moment are determined. A logical map of these selectable items and subcomponents is created for use as a filter for input coordinates received from the input device, with each selectable item mapped to a "region" of the input coordinate field. Upon initiation of the present invention, a start point, in the logical map is determined from for the current location of the input device on screen cursor. A highlight is placed around the onscreen selectable item identified by the start point coordinates according to the map. All input device movements are tracked, and mapped to the logical map of the screen area. If at any time mouse movement causes the cursor to enter the logical region identified in the map with a different selectable item than the one currently highlighted, the highlight is moved to the new selectable item and the old highlight is erased. If the input device indicates the user has selected the highlighted item, the action associated with the item is executed. In this manner, the input device cursor will be constrained to move from one selectable item to the next and never be located in a position where an item may not be selected.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
128 words
A method for input selection of objects within an area of a display screen by means of an input device having coordinates within such area, comprising: identifying selectable items within said area; creating a map of said selectable items; establishing within said area one or more non-overlapping regions, each such region containing a selectable item and being substantially larger in area than such selectable item and all of said regions together in the aggregate occupying a substantial portion of said area; monitoring the coordinates of said input device; determining whenever said coordinates have moved into one of said regions; and whenever it is so determined that said coordinates have moved into one of said regions, remapping said coordinates to new coordinates within the perimeter of the selectable item.
Claim 2
Independent Claim
128 words
A method for input selection of objects within an area of a display screen by means of an input device having coordinates within such area, comprising: identifying selectable items within said area; creating a map of said selectable items; establishing within said area one or more non-overlapping regions, each such region containing a selectable item and being substantially larger in area than such selectable item and all of said regions together in the aggregate occupying a substantial portion of said area; monitoring the coordinates of said input device; determining whenever said coordinates have moved into one of said regions; and whenever it is so determined that said coordinates have moved into one of said regions, remapping said coordinates to new coordinates within the perimeter of the selectable item.
Claim 3
Dependent Claim
43 words
The method of claim 1 further comprising the additional step of highlighting the selectable area associated with the region that the input device coordinates have moved into, and unhighlighting the selectable area associated with the region that said coordinates have moved out of.
Claim 4
Dependent Claim
19 words
A machine readable storage medium on which has been recorded a computer program implementing the method of claim 2.
Claim 5
Dependent Claim
18 words
The method of claim 1 wherein a cursor is displayed at the on-screen position of said new coordinates.
Claim 6
Dependent Claim
19 words
A machine readable storage medium on which has been recorded a computer program implementing the method of claim 4.
Claim 7
Dependent Claim
17 words
The method of claim 1 wherein said non-overlapping regions completely occupy the entire area of said display.
Claim 8
Dependent Claim
23 words
The method of claim 1 wherein there exists at least some portion of said area that is not within one of said regions.
Claim 9
Dependent Claim
31 words
The method of claim 1 wherein the regions correspond with the selectable items in accordance with a relation in which fewer than all of the selectable items are assigned to regions.
Claim 10
Dependent Claim
17 words
The method of claim 8 wherein selectable items which are not assigned to regions are rendered non-selectable.
Claim 11
Dependent Claim
36 words
The method of claim 8 wherein selectable items which are not assigned to said regions are left as being selectable when the coordinates of said input device are directly within the perimeter of such selectable item.
Claim 12
Dependent Claim
19 words
The method of claim 1 wherein the entire capability provided by the claimed method can be activated or deactivated.
Claim 13
Dependent Claim
19 words
A machine readable storage medium on which has been recorded a computer program implementing the method of claim 1.
Claim 14
Dependent Claim
155 words
An interactive electronic apparatus, in which input selection may be made of objects within an area of the display thereof, comprising, a general purpose digital computer; a display screen; an input device; means for identifying selectable items within an area of said display screen; means for creating a map of said selectable items; means for establishing within said area one or more non-overlapping regions, each such region containing a selectable item and being substantially larger in area than such selectable item, and all of said regions together in the aggregate occupying a substantial portion of said area corresponding to said selectable items; means for monitoring the coordinates of said input device; means for determining whenever said coordinates have moved into one of said regions; and means for remapping said coordinates to new coordinates within the perimeter of the selectable item whenever it is so determined that said coordinates have moved into one of said regions.
Claim 15
Dependent Claim
155 words
An interactive electronic apparatus, in which input selection may be made of objects within an area of the display thereof, comprising, a general purpose digital computer; a display screen; an input device; means for identifying selectable items within an area of said display screen; means for creating a map of said selectable items; means for establishing within said area one or more non-overlapping regions, each such region containing a selectable item and being substantially larger in area than such selectable item, and all of said regions together in the aggregate occupying a substantial portion of said area corresponding to said selectable items; means for monitoring the coordinates of said input device; means for determining whenever said coordinates have moved into one of said regions; and means for remapping said coordinates to new coordinates within the perimeter of the selectable item whenever it is so determined that said coordinates have moved into one of said regions.
Claim 16
Dependent Claim
24 words
An interactive electronic apparatus in accordance with claim 13 further comprising means for displaying a cursor at the on-screen position of said new coordinates.
Claim 17
Dependent Claim
46 words
An interactive electronic apparatus in accordance with claim 13 further comprising additional means for highlighting the selectable area associated with the region that the input device coordinates have moved into, and unhighlighting the selectable area associated with the region that said coordinates have moved out of.
