Description
FIELD OF THE INVENTION
[0001] The present invention relates to the field of human to
computer interface systems. In particular the present invention
discloses highly customizable graphical user interface shading
system.
BACKGROUND OF THE INVENTION
[0002] Since the 1980s graphical user interfaces have become the
primary interface between users and computer systems. Graphical
user interfaces present information to computer users in a simple
and intuitive manner. For example, most current word processors
employ a main window with What-You-See-Is-What-You-Get (WYSIWYG)
display of the document and a set of graphical tool icons displayed
on a tool bar for editing the document.
[0003] Many users wish to alter a graphical user interface to adapt
the graphical user interface to their particular personal
preferences. To implement such personalization, many graphical user
interface systems allow a user to select color schemes, alter the
appearance of the graphical user interface icons, modify the
contents of the pull-down menus, and adjust the tools that
available on a particular toolbar.
[0004] Although some graphical user interface systems allow users
to customize some aspects of the graphical user interface, the
amount of customization allowed is limited and the customization
that is available is not very intuitive. In fact, some operating
systems provide such limited customization that is difficult to use
that a user is forced to purchase an add-on extra product if better
customization is desired. Even with the add-on pack, the user is
forced to select from a set of pre-defined graphical user interface
settings. Thus, it would be desirable to provide users with a more
flexible and easier to use graphical user interface customization
tool.
SUMMARY OF THE INVENTION
[0005] To allow users to compensate for different and dynamically
changing lighting conditions, the present invention introduces a
graphical user interface shading system. The graphical user
interface shading system provides a very simple intuitive interface
to the user. In one embodiment, the user is presented with an
adjustable user interface widget such as a slider that allows the
user to select any shading setting along a shading continuum. The
graphical user interface shading system reacts to the users control
by adjusting a number of different graphical user interface
elements in response to the new shading setting. In one embodiment,
the graphical user interface shading system adjusts singled colored
areas with a linear interpolation between two colors provided. Text
areas are handled by selecting a font color dependent on the
shading setting. Icons are handled by selecting a particular icon
bitmap dependent on the shading setting. The shading system handles
textured areas by creating a weighted texture blend between two
textures using the shading setting to select the weighting.
Finally, decals in the user interface are handled by creating a
blend between two decals.
[0006] Other objects, features, and advantages of present invention
will be apparent from the company drawings and from the following
detailed description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] A method and apparatus for a user customized graphical user
interface shading is disclosed. In the following description, for
purposes of explanation, specific nomenclature is set forth to
provide a thorough understanding of the present invention.
[0016] However, it will be apparent to one skilled in the art that
these specific details are not required in order to practice the
present invention. For example, the present invention has been
described with reference to the Macintosh Operating Systems
(MacOS). However, the techniques and teachings of the present
invention can easily be applied to other operating systems or any
system that presents a graphical user interface.
Graphical User Interfaces in Various Environments
[0017] Computer systems are being used in just about every area of
modern life these days. Thus, computers are now used in many
different environments: offices, darkened studios, retail stores,
malls, airports, stadiums, subways, cars, and even outdoors. All of
these different environments present very different lighting
conditions. Offices may have fluorescent lighting, darkened studios
may have low lighting, and outdoor settings may have strong
sunlight.
[0018] Beyond the very different possible lighting conditions for
computer operation, the lighting conditions at any particular
location may vary over time. For example, as the sun moves across
the sky, the lighting in a room with a window will vary
significantly. Furthermore, clouds may move in and obscure the sun,
the sun will eventually set at night, and doors and windows may be
opened or closed thus allowing or blocking sunlight,
respectively.
[0019] With such varied lighting conditions and dynamically
changing light conditions, it would be desirable to provide users
with a simple and effect manner of adjusting the display of a
graphical user interface to best adapt to the current lighting
conditions. To provide such functionality, the present invention
introduces an intuitive adjustable graphical user interface shading
system. The adjustable graphical user interface shading system
allows a user to adjust the shading of the graphical user interface
along a continuum to select a personal preference.
Graphical User Interface Shading System Overview
[0020] To allow users to compensate for different lighting
conditions, some graphical user interface systems allow the user to
change the colors used to render the graphical user interface.
However, such simple customization systems fall short of providing
a satisfactory means to allow a user to adjust the graphical user
interface in response to different lighting conditions.
[0021] The present invention introduces a sophisticated graphical
user interface shading system that provides a very simple intuitive
interface to the user. In the system of the present invention, the
user is presented with an adjustable user interface widget that
allows the user to select any location along a shading continuum.
In one embodiment, the shading continuum varies from a very dark
background with light colored text and icons to a very light
background with dark colored text and icons.
[0022] In one embodiment the graphical user interface shading
system of the present invention, the adjustable user interface
widget is a slider bar that allows the user to slide an indicator
along a defined range. However, other adjustable user interface
widgets may also be employed. For example, the radio-dial knob, a
digital display with up and down adjustment buttons, or any other
adjustable user interface widget that allows a user to select a
value within a define range may be used.
Graphical User Interface Shading System Details
[0023] To describe the graphical user interface shading system of
the present invention, one particular implementation will be
described with reference to FIGS. 1A to 3. However, it should be
noted that specific implementation details selected in the
disclosed implementation are not required to practice the teachings
of the present invention.
[0024] FIG. 1A illustrates an example embodiment of a graphical
user interface employing the graphical user interface shading
system of the present invention. The left side of FIG. 1A
illustrates a user interface adjustment window 111 that contains a
slider bar 121. As illustrated in FIG. 1A, an indicator on the
slider bar 121 is set to the left most position for a zero ("0")
shading setting value as indicated by amount indicator 119. The
indicator on the slider bar 121 may be adjusted to the right to
change the shading setting of the graphical user interface. When
the indicator on the slider bar 121 is adjusted all the way to the
right of the slider bar 121 then the shading setting in the amount
indicator 119 will display "100".
[0025] Below slider bar 121 and amount indicator 119 is a save
button 128. Save button 128 allows the user to save the current
shading setting. In the embodiment of FIG. 2, the user may save the
current shading setting into any of the four custom shading setting
buttons that are below save button 128. The saved shading setting
may be recalled by pressing the associated custom shading setting
button.
[0026] The right side of FIG. 1A illustrates an application window
139 containing the graphical user interface for a video editing
program. The shading of the video editing program graphical user
interface is controlled using the slider bar 121 in the user
interface adjustment window 111. The application window 139
contains many different user interface elements that are displayed
to the user. Each of these different user interface elements must
be adjusted by the shading system to present a consistent graphical
user interface shading experience to the user. Each user interface
element will be discussed in detail.
Flat Single Color Areas of the Graphical User Interface
[0027] Large areas of the graphical user interface for an
application are filled with a single flat background color. For
example, area 131 of FIG. 1A is filled with a solid background
color that acts as the background for a list of file names. The
graphical user interface shading system of the present invention
handles flat areas by having the application programmer design
supply two different pixel color values that represent the two
color extremes (color 1 and color 2) for the two extremes of the
shading system (setting 0 and setting 100, respectively). The
graphical user interface shading system then selects a color for
the area by determining a linear interpolation between the two
colors.
[0028] FIG. 2 illustrates a conceptual diagram that describes how
the graphical user interface shading system of the present
invention handles different user interface elements. FIG. 2
illustrates a shading slider 221 that is a representation of the
shading slider 121 of FIG. 1A. Below the shading slider 221 of FIG.
2 is a color luminance scale 230 aligned with the shading slider
221 that has color 1 on the left and color 2 on the right. In one
embodiment, color 1 and color 2 have the same hue (H) and
saturation (S) but only differ by their luminance value (V). In
such an embodiment, the system reads the shading setting and
determines a linear interpolation between the two color values
(color 1 and color 2). For example, FIG. 2 illustrates a dotted
line that represents a shading setting of 15. With such a shading
setting, the graphical user interface shading system of the present
invention determines a color with a luminance value that is 15%
between the luminance of color 1 and the luminance of color 2.
Text Sections of the Graphical User Interface
[0029] Even graphical user interfaces contain significant amounts
of alphanumeric text material. Thus, the graphical user interface
shading system of the present invention must handle shading
adjustments of such alphanumeric text. To handle text, the
graphical user interface shading system uses the shading setting to
select a font color to use.
[0030] FIG. 2 illustrates a conceptual diagram of a text color
selection look-up table 240. The text color selection look-up take
specifies what color of text should be used for a particular
shading setting. In the embodiment of FIG. 2, black text is used up
until the "60" shading setting. For higher shading settings, which
colored text is used. Ideally, the text color look-up table should
be created in concert with the various background area colors such
that adequate contrast between the text and the background color is
maintained for all shading settings.
[0031] The embodiment illustrated in FIG. 2 uses only black text
for a certain range of the shading setting and then white text for
the remainder of shading settings. However, there is no limitation
to just having two font colors.
Graphical User Interface Icons
[0032] Most graphical user interfaces also contain simple icons
that users may view and interact with in addition to text. For
example, FIG. 1A illustrates application window 139 that contains
clock icon 151.
[0033] The graphical user interface shading system of the present
invention handles the shading adjustments of simple icons in a
mariner similar to the system for handling text. Specifically, the
graphical user interface designer creates a set of different icons
for different shading ranges. The graphical user interface designer
then specifies a shading range that defines when each icon will be
used.
[0034] FIG. 2 illustrates an icon selection look-up table 250 for
selecting a particular icon representation that will be used to
drawing the icon. In the embodiment of FIG. 2, a first icon is used
from shading range 0 to 30, a second icon is used from 30 to 75,
and a third icon is used from 75 to 100. However, the shading
setting continuum may be divided into any number of different
ranges with each range having an associated icon representation
that should be used within that range.
Textured Areas of the Graphical User Interface
[0035] Instead of simply using a single color, some areas of user
interfaces use `textures` to provide a more life-like appearance. A
texture is a two-dimensional bit-mapped image that may be used to
cover any surface. For example, area 161 in FIG. 1A is rendered
with a texture.
[0036] The graphical user interface shading system of the present
invention handles textures by having the graphical user interface
define two different textures for the two shading settings
extremes. Specifically, the graphical user interface designer
submits a first texture (texture 1) for the 0 shading setting and a
second texture (texture 2) for the 100 shading setting. The
graphical user interface shading system then generates a weighted
blend of the two textures depending on the shading setting. The
weighted blend varies from 100% texture 1 at shading setting 0 to
100% texture 2 at shading setting 100. FIG. 2 conceptually
illustrates the system with texture blend diagram 260.
User Interface Decals
[0037] Certain user interface devices are more complex than simple
icons. To render more complex user interface devices, a graphical
user interface may use `decals.`. A decal is a small
two-dimensional object that may be rendered on the screen. For
example, user interface device 171 in FIG. 1A is rendered with a
decal.
[0038] The graphical user interface shading system of the present
invention handles decals in the same manner that textures are
handled. Specifically, the graphical user interface designer
creates a first decal (decal 1) for the 0 shading setting and a
second decal (decal 2) for the 100 shading setting. The graphical
user interface shading system then generates a weighted blend of
the two decals depending on the shading setting. The weighted blend
varies from 100% decal 1 at shading setting 0 to 100% decal 2 at
shading setting 100. FIG. 2 conceptually illustrates the texture
blending system with texture blend diagram 260.
Graphical Shading System Implementation
[0039] FIG. 3 illustrates a flow diagram that describes how one
embodiment of the graphical user interface shading system may
operate. Referring to FIG. 3, when the application first begins
execution, the shading system loads the previous shading setting or
a default shading setting (depending on the implementation) at step
310. In the embodiment described with reference to FIGS. 1A to 2,
the shading setting may be a value from 0 to 100.
[0040] Next, at step 320, the shading system determines the colors
that will be used in areas filled in with a flat single color. As
set forth in step 320, the shading system selects a linear
interpolation between the two colors defined for each area (color 1
and color 2). In a preferred embodiment, the interpolation is only
along a luminance difference between color 1 and color 2. The
interpolated color for each area will be used to fill in the
background for that area.
[0041] At step 330, the shading system addresses text elements. For
each font used, the shading system uses the shading setting as an
index into a look-up table associated with that font to determine
what color will be used to render the font on the screen. Note that
different fonts may use different look up tables or all the fonts
may use the same look-up table.
[0042] Next, at step 340, the shading system handles icons. For
each icon that is used in the graphical user interface, the shading
system uses the shading setting as an index into a look-up table
associated with the icon to determine which bitmap will be used to
render the icon on the screen.
[0043] Then, at step 350, the shading system creates a set of
textures to use for the textured areas of the graphical user
interface. For each different texture, the shading system creates a
weighted texture blend using the two textures provided by the
graphical user interface designer. The blended texture will be used
in the associated textured areas of the graphical user
interface.
[0044] Finally, at step 360, the shading system creates a set of
decals to represent user interface objects. For each decal in the
graphical user interface, the shading system creates a weighted
decal blend using the two decals (decal 1 and decal 2) provided by
the graphical user interface designer for the two shading extremes.
The graphical user interface is then rendered using the blended
decal.
[0045] After step 360, the application program runs normally using
the background colors, font colors, icons, blended textures, and
blended decals created for that particular shading setting.
However, if the user changes the shading setting, then the shading
system returns to step 320 to create a new set of background
colors, font colors, icons, blended textures, and blended decals
created for the new shading setting.
Graphical User Interface Shading System Example
[0046] To illustrate how the graphical user interface shading
system operates in an actual application, FIGS. 1A to 1E illustrate
how the appearance of an example graphical user interface change as
the shading setting value is moved from 0 to 100 in four increments
of 25.
[0047] Initially, in FIG. 1A, the graphical user interface of the
application window 139 features black text 141 on light backgrounds
131. The icons, such as icon 151, are also block like the text. The
textured areas, such as texture 161, are light colored like the
single colored background area 131. Finally, the decals such as
decal 171 are also relatively light.
[0048] When a user moves the indicator on the shading slider 121 to
the right to the `25` shading setting, the graphical user interface
of the application window will appear as shown in FIG. 1B. Note
that in FIG. 1B, the text 142 and the icons 152 are still black.
However, the single colored background 132, texture 162, and decal
172 have become darker.
[0049] When a user moves the indicator on the shading slider of
FIG. 1B even further to the right, to the `50` shading setting, the
graphical user interface of the application window will appear as
shown in FIG. 1C. Again, note that in FIG. 1C, the text 143 and the
icons 153 are still black. However, the single colored background
133, texture 163, and decal 173 have become even darker due to the
blending.
[0050] When a user moves the indicator on the shading slider of
FIG. 1C even further to the right, to the `75` shading setting, the
graphical user interface of the application window will appear as
shown in FIG. 1D. In FIG. 1D, the single colored background 134,
texture 164, and decal 174 have become yet even darker due to the
blending. However, in FIG. 1D, the text 144 and the icons 154 are
now rendered in white to provide greater contrast with the darkened
background.
[0051] Finally, when a user moves the indicator on the shading
slider of FIG. 1D completely to the right-hand side to the `100`
shading setting, the graphical user interface of the application
window will appear as shown in FIG. 1E. As was illustrated in FIG.
1D, the text 145 and the icons 155 are rendered in white to
contrast with the very dark background areas. Specifically, the
single colored background 135, texture 165, and decal 175 have
become very dark since the dark color 2, the dark texture 2, and
dark decal 2 are used, respectively.
[0052] The foregoing has described a graphical user interface
shading system. It is contemplated that changes and modifications
may be made by one of ordinary skill in the art, to the materials
and arrangements of elements of the present invention without
departing from the scope of the invention.
