Embodiments of the present invention may be embodied as, among other things: a method, system, or set of instructions embodied on one or more computer-readable media. Computer-readable media include both volatile and nonvolatile media, removable and nonremovable media, and contemplates media readable by a database, a switch, and various other network devices. By way of example, and not limitation, computer-readable media include media implemented in any method or technology for storing information. Examples of stored information include computer-useable instructions, data structures, program modules, and other data representations. Media examples include, but are not limited to information-delivery media, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile discs (DVD), holographic media or other optical disc storage, magnetic cassettes, magnetic tape, magnetic disk storage, and other magnetic storage devices. These technologies can store data momentarily, temporarily, or permanently.
Embodiments of the present invention provide systems, methods, and computer-readable media for distributing icons so that they do not overlap certain screen areas of a mobile device. In particular, screen areas of a background image displayed on a screen of a mobile device may be identified as image portions that are desirable for protection. The personalization of protected image portions of a mobile device screen may be desirable to users. For example, a user who displays a family portrait as a background image on a screen of a mobile device may wish to keep icons from covering desired image portions, such as the faces of family members. In embodiments of the invention, icons may comprise user interface elements, items, desktop widgets, etc.
In embodiments of the present invention, the screen of the mobile device is logically divided into display divisions. For example, the display divisions may be divided into a grid pattern. In embodiments, icons may populate the grid-patterned display divisions in a logical manner, such as from top-to-bottom and left-to-right. Alternative embodiments envision other logical divisions of display divisions and/or other patterns of icon population that are systematic. As such, systematic divisions and/or patterns may be capable of resulting in different configurations of icons populating the screen of the mobile device.
When a background image is selected by a user, the icons populating the grid-patterned display divisions may be ordered independent of what is displayed on the background. This, in turn, may result in the icons fully or partially covering desired image portions of the background image. In order to ensure that the view of desired image portions of a background image are protected from obstruction by icons, the desired image portions may be identified and protected. The icons may then be presented in a way so as to avoid populating display divisions covering the desired image portions. In embodiments, display divisions covering the desired image portions may be referred to as “protected areas.”
Desirable image portions may be identified by a user. A user may select a portion of a background image for protection, such as a face of a loved one. In response to the user's selection of a desired image portion, a protective circle may be placed over that portion of the background image. The user may select the size (for example, the length of the radius) of the protective circle. Alternatively, a computer program auto-selects the size of the circle that is desired based upon features in the picture. For example, if a user selects a face of a loved one to be protected, the computer program may identify the nearest face through the use of facial recognition software, and may establish a protected area through the use of a protective circle having a minimum radius necessary to encompass the primary facial characteristics of the face as determined by the software. In further embodiments, the protective circular areas may have a buffer area that is also protected from obstruction by an icon. For example, a user may select the face of a loved one but may also desire for an extra half-centimeter radius to be included in the measure of the radius to keep icons from being presented too close to the desired image portion. In embodiments, a desired image portion may also be referred to as a selected image portion.
In alternative embodiments, desirable image portions are identified by an algorithm or other computer-executable instructions. In particular, desirable image portions may be identified through the use of facial recognition software as discussed above. Additionally, the area of the protective circle used to protect the identified facial features may be buffered by an increase in the radius of the circle used to protect the image. This increase in radius may be a factor set by the user.
Once an image portion has been designated as being protected, icons may be prevented from fully or partially obstructing the protected image portion. In embodiments, display divisions that correspond to all or part of a protected area of an image portion may be designated as unavailable to display an icon. Accordingly, when icons are presented, they will be presented in a default pattern that recognizes display divisions that are occupied. In alternative embodiments, when icons are moved by a user, areas associated with display divisions that correspond to all or part of a protected area of an image portion may be unavailable to host icons. For example, when a user tries to move an icon over a protected area, the icon may be assigned to the nearest available display division. As such, in embodiments, a user is unable to move icons to partially or fully obstruct protected areas.
In further embodiments, the placement and/or size of display divisions are dependent upon the size of selected image portions. For instance, if an image portion takes up more than a threshold percentage of the area of a screen, e.g., 30%, the size of the display division and, accordingly, the size of the icons may be reduced. Accordingly, display divisions may also be tailored to match the size of the selected image portions.
Turning now to FIG. 1, an illustrative mobile device is provided in accordance with an embodiment of the present invention and referenced by the numeral 100. For brevity or as a shorthand form, this description might refer to a “device” instead of a “mobile device.” This shorthand does not mean to imply a distinction with the different terms. In addition, a mobile device may refer to a number of different devices such as a cell phone or a PDA.

In sum, FIG. 1 is not meant to indicate all, or even major, systems or components of mobile device 100. An overview of mobile device 100 is presented and certain components are listed so as to be able to refer to them throughout this disclosure.
In order to protect desired portions of a background image from being populated by icons, a portion may first be identified to be protected. FIG. 2 depicts an illustrative selected image portion 210 of a background image 200 in accordance with an embodiment of the present invention. Selected portion 210 of a background image 200 may be selected through the use of an algorithm used to identify desirable characteristics, such as facial characteristics. Algorithms may be executed through the use of application 140. Alternatively, image portion 210 are manually selected by a user. Whereas image portion 210 is encapsulated by a circle, in alternative embodiments, the shape of the boundary of a selected image portion may vary. For example, with regard to background image 200, an alternative selected image portion may include the shape of the tulip head. Alternatively, a selected image portion may include the shape of a square, an oval, and/or a rectangle, etc.
In addition to a selected portion, a buffer area may be identified to be protected from the population of icons. FIG. 3 depicts an illustrative selected portion 310 of a background display 300 with a buffer area in accordance with an embodiment of the present invention. The buffer area includes the area between a dashed-line alternative selected portion 320 and the solid-line selected portion 310. A user may select a control option to choose to have a buffer area surround a selected portion 310. In further embodiments, a buffer region may be determined based on the size of a selected portion. For example, application 140 may identify a selected portion. Subsequent to the identification of the selected portion, application 140 may add a buffer area proportional to the size of the selected portion, e.g. application 140 may add a buffer area extending 1⁄4 the radius of the circle encapsulating the selected portion. In embodiments, as icons begin to fully populate non-protected screen areas, the buffer area may be reduced or eliminated so as to make additional space available to populate icons.
FIG. 4 depicts an illustrative selected portion 410 from a group of image portions 420 of a background display 400 in accordance with an embodiment of the present invention. The image portions 420 of FIG. 4 may be identified by an algorithm, such as application 140, that identifies unique image portions of an image. Unique image portions may include a complexity of shapes and/or colors. As seen in FIG. 4, each of the tulip heads would be identified as a unique image portion 420. From among the unique image portions 420, a user may select one image portion 410 to signify an area the user would like to protect from being covered by icons.
A selected portion identified from a group of image portions, such as that seen in FIG. 4, may also be surrounded by a buffer area that is also protected from icon population. FIG. 5 depicts an illustrative portion 510 with a buffer area selected from a group of image portions 520 of a background display 500 in accordance with an embodiment of the present invention. Similar to FIG. 4, the image portions 520 of FIG. 5 may be identified by an algorithm that identifies unique image portions of an image. Unique image portions may include a complexity of shapes and/or colors. As seen in FIG. 5, each of the tulip heads would be identified as an unique image portion 520. From among the unique image portions 520, a user may select one image portion 510 to signify an area the user would like to protect from being covered by icons. Additionally, FIG. 5 also includes a representation of an alternative selected portion 530 that includes a buffer area between the dashed-line alternative selected portion 530 and the solid-line selected portion 510. In alternative embodiments, a user selects a control option to have a buffer area surround a selected portion 510.
In addition to desired images of flowers, faces may also be protected from being overlapped by icons. These faces may also include a choice of varying degrees of buffer areas to surround one or more faces. FIG. 6 depicts an illustrative facial image portion 610 with buffer areas selected from a group 640 of facial image portions of a background display 600 in accordance with an embodiment of the present invention. Similar to FIG. 5, the group 640 of facial image portions of FIG. 6 may be identified by an algorithm that identifies facial image portions of an image. Facial image portions may be recognized through the use of facial recognition software executed by an application, such as application 140. As seen in FIG. 6, each of the faces presented would be identified as part of the group 640 of facial image portions. From among the group 640 of facial portions, a user may select one image portion 610 to signify an area the user would like to protect from being covered by icons. Additionally, FIG. 6 also includes representations of alternative selected portions 620 and 630 that include buffer areas between the dashed-line alternative selected portion 630 and the solid-line selected portion 620, and between dashed-line alternative selected portions 620 and 610, respectively. In alternative embodiments, a user selects a control option to have a buffer area surround a selected portion 610.
In determining selected areas to be protected from overlapping icons, more than one facial image may be identified. FIG. 7 depicts illustrative selected portions 710 from a group 720 of facial image portions 720 of a background display 700 in accordance with an embodiment of the present invention. The group 720 of facial image portions of FIG. 7 may be identified by an algorithm that identifies facial image portions of an image. Facial image portions may be recognized by a computer program, such as application 140, through the use of facial recognition software. As seen in FIG. 7, each of the faces displayed in background image 700 would be identified as part of the group 720 of facial image portions. From among the group 720 of facial image portions, a user may select image portions 710 to signify areas the user would like to protect from being covered by icons.
In order to affirm the selection of protected image portions, a user may be shown a user interface to affirm the selection of image portions to be protected. Accordingly, FIG. 8 depicts an illustrative user interface 800 presented on display screen 810 of mobile device 820 in accordance with an embodiment of the present invention. User interface 800 includes background image 830, selected image portions 840, a modify button 850, and an accept button 860. In embodiments, application 140 generates user interface 800. Application 140 may then receive one or more inputs from user 820 in response to user interface 800. Application 140 may then modify or affirm a selected presentation of icons in accordance with the input received from user 820. User interface 800 is presented to the user 820 in order to allow the user 870 to modify or affirm the selected image portions 840 presented in accordance with embodiments of the present invention.
FIG. 9 depicts an illustrative background image 900 used in embodiments of the present invention. Additionally, FIG. 10 depicts an illustrative display of icons 1010 presented on top of background image 1000 used in embodiments of the present invention. Accordingly, FIGS. 9 and 10 indicate conditions of a mobile screen device before the application of embodiments of the present invention.
A presentation of icons covering the face of an individual depicted in a background image is shown in FIG. 11. FIG. 11 depicts an illustrative graphical display of icons 1110 presented in a grid pattern 1120 on top of a background image 1100 in accordance with an embodiment of the present invention. While the presentation pattern of the icons 1110 in FIG. 11 is top-to-bottom and left-to-right, other presentation patterns may be used in the population of icons. As seen in FIG. 11, however, the result of a standard pattern used to populate icons 1110 has partially obscured a face of an individual in the background image 1100.
In order to protect portions of a background image from being obscured, desirable portions may be selected for protection from icon overlapping. FIG. 12 depicts an illustrative selected portion 1210 of a background image 1200 in accordance with an embodiment of the present invention. Similar to FIG. 2, selected portion 1210 of a background image 1200 may be selected through the use of an algorithm used to identify desirable characteristics, such as facial characteristics. Alternatively, image portion 1210 is manually selected by a user. Whereas image portion 1210 is encapsulated by a circle, in embodiments, the shape of the boundary of a selected image portion may vary. For example, with regard to background image 1200, an alternative selected image portion may include the shape of a square, an oval, a rectangle, etc. As used in FIG. 12, it can be seen that all faces of the representative family are included in image, but the face of the dog is only partially protected.
Once image portions have been selected, a determination is made as to which areas of the display of the mobile screen should be protected from icon population. FIG. 13 depicts an illustrative grid-patterned 1320 selected portion 1310 of a background image 1300 in accordance with an embodiment of the present invention. In embodiments, grid blocks represent the logically divided display divisions as discussed above. It can be seen from FIG. 13 that grid blocks B-D, G-I, and L-N include part of selected portion 1310. Accordingly, grid blocks B-D, G-I, and L-N may be selected to be protected from icon population in accordance with embodiments of the present invention.
The protections of blocks B-D, G-I, and L-N from icon population is illustrated in FIG. 14. FIG. 14 depicts an illustrative grid-patterned 1420 selected portion 1410 of a background image 1400 covered by a protection block 1430 of a background image in accordance with an embodiment of the present invention. As seen in FIG. 14, the grid blocks that include the protection block 1430 are B-D, G-I, and L-N. As such, the protection block includes each grid block that includes at least part of selected portion 1410.
Once a protection block has been identified, icons may populate the remaining, unprotected portions of a mobile screen. FIG. 15 depicts an illustrative presentation of icons 1530 on a grid-patterned 1520 selected portion 1510 of a background image 1500 in accordance with an embodiment of the present invention. As seen in FIG. 15, icons 1530 populate the grid 1520 in accordance with protection block 1430, identified in FIG. 14, so as to avoid covering selected portion 1510 of background image 1500. This is in contrast to FIG. 11, where the population of icons 1110 was independent of protected portions of a background image.
As seen in FIG. 16, in accordance with embodiments of the present invention, the resulting display screen of a mobile device provides a presentation of icons that is consistent with the protected portions of a background image. FIG. 16 depicts an illustrative presentation of icons 1610 in accordance with a selected portion of a background image 1600 in accordance with an embodiment of the present invention. FIG. 16 presents an alternative resultant image showing the distribution of icons in accordance with an embodiment of the present invention as would be seen on a screen of a mobile device. In some embodiments, resultant FIG. 16 may be the result of a redistribution of icons that have already begun to encroach on desired image portions. In alternative embodiments, the distribution of icons are be ordered to prevent overlapping with a selected portions from occurring as icons are added to the screen of the mobile device.
In addition to the embodiment of the invention discussed above, a distribution of icons may be presented in accordance with a buffer area around a selected portion. Accordingly, FIG. 17 depicts an illustrative selected portion 1710 of a background display 1700 with a buffer area in accordance with an embodiment of the present invention. The buffer area includes the area between selected portion 1710 and alternative selected portion 1720. Similar to FIG. 12, selected portion 1710 and alternative selected portion 1720 of a background image 1700 may be selected through the use of an algorithm used to identify desirable characteristics, such as facial characteristics. Alternatively, image portions 1710 and 1720 are manually selected by a user. Whereas image portions 1710 and 1720 are encapsulated by a circle, in embodiments, the shape of the boundary of a selected image portion may vary. For example, with regard to background image 1700, an alternative selected image portion may include the shape of a square, an oval, and/or a rectangle, etc. As used in FIG. 17, it can be seen that all faces of the representative family are included in image portion 1710. Additionally, in contrast to FIG. 12, image portion 1720 includes the faces of the family, and also includes the face of a dog.
Once an image portion and a buffer area has been selected, a determination is made as to which areas of the display of the mobile screen should be protected from icon population. FIG. 18 depicts an illustrative grid-patterned 1830 alternative portion 1810 of a background image 1800 with a buffer area in accordance with an embodiment of the present invention. The buffer area includes the area between selected portion 1810 and alternative selected portion 1820. Due to the increase in the radius of selected portion 1810, it can be seen from FIG. 18 that grid blocks B-D, G-I, L-N, and Q-S include part of selected portion 1810. In embodiments, grid blocks represent the logically divided display divisions as discussed above.
The protections of blocks B-D, G-I, L-N, and Q-S from icon population is illustrated in FIG. 19. FIG. 19 depicts an illustrative grid-patterned 1930 selected portion 1910 of a background image 1900 covered by a protection block 1940 with a buffer area in accordance with an embodiment of the present invention. The buffer area includes the area between selected portion 1920 and alternative selected portion 1910. As seen in FIG. 19, the grid blocks that include the protection block 1940 are B-D, G-I, L-N, and Q-S. As such, the protection block includes each grid block that includes at least part of alternative portion 1920.
Once a protection block has been identified, icons may populate the remaining, unprotected portions of a mobile screen. FIG. 20 depicts an illustrative presentation of icons 2040 included on a grid-patterned 2030 selected portion 2010 of a background image 2000 with a buffer area in accordance with an embodiment of the present invention. The buffer area includes the area between selected portion 2010 and alternative selected portion 2020. As seen in FIG. 20, the icons 2040 populate the grid 2030 in accordance with protection block 1940, identified in FIG. 19, so as to avoid covering the selected portion 2010 of background image 2000. This is in contrast to FIG. 11, where the population of icons 1110 was independent of protected portions of a background image.
As seen in FIG. 21, in accordance with embodiments of the present invention, the resulting display screen of a mobile device provides a presentation of icons that is consistent with the protected portions of a background image. FIG. 21 depicts an illustrative presentation of icons 2110 consistent with a selected portion of a background image with a buffer area in accordance with an embodiment of the present invention. FIG. 21 presents an alternative resultant image showing the distribution of icons in accordance with an embodiment of the present invention as would be seen on a screen of a mobile device. In some embodiments, resultant FIG. 21 may be the result of a redistribution of icons that have already begun to encroach on desired image portions. In alternative embodiments, the distribution of icons are ordered to prevent overlapping with a selected portions from occurring as icons are added to the screen of the mobile device.
FIG. 22 is a flow diagram 2200 showing an embodiment of a method of preventing icons from overlapping one or more portions of a background image presented on a display of a mobile device, in accordance with an embodiment of the present invention.
At step 2210, the background image is presented on the display of the mobile device. The display is logically dividable into a plurality of display divisions. Each display division is capable of presenting an icon. In alternative embodiments, the display divisions include one or more icons. In further alternative embodiments, the display divisions are capable of presenting a portion of an icon. In other words, display divisions may be set to a small enough size that multiple display divisions would be required to host each icon. In this embodiment, desired image portions may be more narrowly selected, allowing for the potential presentation of more icons in the larger, non-selected image portions. At step 2220, one or more image portions of said background image are identified that are to be unobstructed by any icon. The one or more image portions may be selected by a user or may be selected through the use of an algorithm. At step 2230, a set of display divisions are identified that include at least some of said one or more image portions. In alternative embodiments, display divisions that contain only a fraction of an image portion are also identified. At step 2240, a set of icons is presented on said display such that no portion of any icon of said set occupies any display division of said set of display divisions.
FIG. 23 is a flow diagram 2300 showing an embodiment of a method of prioritizing viewability of one or more desired portions of a background image presented on a mobile device, in accordance with an embodiment of the present invention. At step 2310, the background image is presented on a display of the mobile device. The background image includes desired feature components. At step 2320, desired feature components are identified from the background image. The desired feature components may be identified by a user. Additionally or alternatively, desired feature components are identified through the use of a computing algorithm. At step 2330, a user interface is presented on the mobile device to a user that includes an indication of desired feature components. In embodiments of the invention, the user may select the size (e.g., screen area occupied) and/or shape of the boundaries used to define the desired feature components. Additionally or alternatively, the user indicates protected areas that are to cover the desired feature components so as to make the protected areas unavailable for population by icons. In alternative embodiments, a user prioritizes certain desired feature components over other desired feature components such that, if the user chooses, one or more of the desired feature components may take up less screen area or may be eliminated completely as the room for icons becomes unavailable. In these embodiments, a user may decide to prioritize the face of a family pet, such as the dog in FIGS. 9-21. However, as available space for presenting icons diminished, the user may prioritize the extra icon space more than the protection of the dog's face from being overlapped by icons. At step 2340, one or more icon images is presented in accordance with the prioritization of the desired feature components of the background image.
FIG. 24 is a flow diagram 2400 showing an embodiment of a method of modifying the presentation of icon images on a display of a mobile device, in accordance with an embodiment of the present invention. As indicated at step 2410, a user interface that includes at least one icon image that overlaps the background image is presented on a display of the mobile device. At step 2420, a set of desired feature components is identified from the background image. The desired feature components may be identified by a user. Additionally or alternatively, desired feature components are identified through the use of a computing algorithm. At step 2430, screen areas corresponding to the set of desired feature components are designated as being unavailable to display an icon image. The protective screen areas may be defined by a user. Alternatively, the protective screen areas are selected by an algorithm. At step 2440, the presentation of the at least one icon image is modified in accordance with the designation of the set of desired feature components.
