Abstract
Abstract A wireless user station (10), such as a cellular telephone, is provided with a touch sensitive input device, such as a touch-sensitive display (20) or a touchpad (23). A display device displays a plurality of symbols. A first location of a tactile input is detected and displayed symbols in the vicinity of the first location of the tactile input are magnified to occupy a larger display area. Subsequently, a second location of the tactile input is detected, thereby identifying a new position of the user's fingertip. After the second location on the touch sensitive screen remains constant, or after the user lifts the fingertip, the second location of the tactile input is reported and associated with the selected symbol. <IMAGE>

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
80 words
A method for operating a wireless communicator having a display and a touch
sensitive input device, said display displaying a plurality of symbols, comprising the
steps of: detecting a first location of a tactile input on the touch sensitive input device; magnifying one or more displayed symbols in the vicinity of the first location; detecting a second location of the tactile input after magnifying the displayed
symbols; and associating the second location of the tactile input with a selected symbol.
Claim 2
Dependent Claim
24 words
A method for operating a wireless communicator as in claim 1, wherein the
magnifying step magnifies the symbols in one or more magnification increments.
Claim 3
Dependent Claim
38 words
A method for operating a wireless communicator as in claim 1, wherein the
magnifying step magnifies a symbol that corresponds to a current location of the tactile
input so as to appear larger than all other displayed symbols.
Claim 4
Dependent Claim
32 words
A method for operating a wireless communicator as in claim 1, wherein the
magnifying step includes a step of emulating an effect of a lens disposed between the
display and the user.
Claim 5
Dependent Claim
45 words
A method for operating a wireless communicator as in claim 1, wherein the
magnifying step includes a step of displaying a user-selected symbol with a
predetermined size, and displaying other symbols with a size that decreases in
proportion to their distance from the user-selected symbol.
Claim 6
Independent Claim
29 words
A method for operating a wireless communicator as in any of claims 1 to 3,
wherein the magnifying step is repeated a plurality of times with increasing magnification
ratios.
Claim 7
Independent Claim
36 words
A method for operating a wireless communicator as in any of claims 1 to 6,
wherein the associating step is performed after a predetermined timeout period wherein
a location of the tactile input does not change.
Claim 8
Independent Claim
27 words
A method for operating a wireless communicator as in any of claims 1 to 6,
wherein the associating step is performed after the tactile input is removed.
Claim 9
Dependent Claim
81 words
A wireless communicator, comprising: a display; an input device having a touch sensitive surface; and a controller coupled to said display and to said input device for detecting a first
location of a user's tactile input on said touch sensitive surface, for magnifying
one or more displayed symbols in the vicinity of said first location, for detecting a
second location by means of the user's tactile input, and for associating said
second location with a magnified symbol selected by the user.
Claim 10
Dependent Claim
18 words
A wireless communicator as in claim 9, wherein said touch sensitive surface
is a surface of said display.
Claim 11
Dependent Claim
36 words
A wireless communicator as in claim 9, wherein said touch sensitive surface
is a surface of a touch pad that is one of disposed external to said communicator or
disposed upon a surface of said communicator.
Claim 12
Dependent Claim
37 words
A wireless communicator as in any of claims 9 to 11, wherein said controller
magnifies a symbol that corresponds to a current location of the tactile input so as to
appear larger than all other displayed symbols.
Claim 13
Dependent Claim
29 words
A wireless communicator as in any of claims 9 to 11, wherein said controller
magnifies the one or more displayed symbols a plurality of times with increasing
magnification ratios.
Claim 14
Dependent Claim
