DETAILED DESCRIPTION
It should be understood at the outset that although an illustrative implementation of one embodiment of the disclosure is illustrated below, the system may be implemented using any number of techniques, whether currently known or in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary design and implementation illustrated and described herein, but may be modified within the scope of the appended claims along with their full scope of equivalents.
The physical components that allow the display of images on a handset will be referred to herein as a display and will be described hereinafter. The image that appears on the display when a handset is initially turned on can be referred to as the home screen or the idle screen. The home screen is typically a graphical user interface through which a user can navigate and which allows the entry and display of data. The home screen typically displays a portion of the menu system that is used to access the functions of the handset and might also display icons, message alerts, and other information.
In embodiments of the disclosure, a home screen of a handset displays a ‘virtual world’ containing a plurality of objects that share a common theme. That is, a substantial portion of the objects appear to intrinsically belong in the scene depicted in the virtual world. For example, if the virtual world depicted a beach scene, the objects in the virtual world might include a beach, an ocean, a boat, an island, and other items that might logically belong in or fit into a beach-related theme. If the virtual world depicted a city scene, the objects in the virtual world might include buildings, streets, cars, and other items that might belong in a city-related theme. The virtual world might depict a real location, such as Waikiki Beach or New York City, or might depict a fictional but readily identifiable location, such as a generic beach or a generic city.
At least some of the objects in the virtual world are able to move about in the virtual world. For example, in a beach scene, a boat might appear to move across the water. In a city scene, a car might appear to move along a street. In either type of scene, an airplane or the sun might appear to move through the sky. In other scenes, other types of motion might be possible.
The objects in the virtual world might allow actions to be performed on the handset. For example, an object may act as a shortcut to a handset application, whereby selection of the object launches the application. Alternatively, selection of an object might cause a menu to be displayed, might allow settings to be adjusted, or might allow a user to perform other functions that are typically performed when traditional menu items are selected. In addition, an object might provide the user of the handset with information such as alerts, news updates, or weather information. For example, the movement of an object through the virtual world might indicate that a message has arrived or the movement of the sun through the sky might indicate the passage of time. Information might also be conveyed by a previously invisible object becoming visible or by an object changing its appearance or in other ways.
Only a portion of the virtual world may be visible on the home screen at any time. A handset user can use the navigation keys or other input mechanisms on the handset to pan through the home screen and bring other portions of the virtual world into view. For example, the user might pan left, right, up, or down through the home screen to reveal other objects that are present in the virtual world but cannot currently be seen.
The objects that appear in the virtual world might be provided with scaling, shadowing, and other well-known effects that can give a three-dimensional appearance to the objects and to the virtual world in which the objects appear. That is, each object can be made to appear to have depth rather than being two-dimensional and some objects might appear to be closer to the user than other objects. Navigation keys or other input mechanisms on the handset might be used to create an appearance of moving into and out of the virtual world so that objects at different apparent depths can be approached or selected.
FIG. 1 illustrates an embodiment of a virtual world 100 that might appear as a home screen on a display of a handset. In this example, a beach scene is depicted in which a plurality of beach-related objects are present, including a beach 110 and a body of water 120. A plurality of natural objects, such as a mountain 112 and a tree 116, might appear on the beach 110. The beach 110 might also include a plurality of man-made objects such as a building 114. A plurality of natural objects, such as an island 122, and a plurality of man-made objects, such as a boat 124, might appear on the water 120. An airplane 130, the sun 140, and other objects might appear in the sky 150 of the virtual world 100.
A user can navigate through the virtual world 100 and cause different portions of the virtual world 100 and different objects to be displayed on the home screen of the user's handset. For example, a user might pan downward or to the left to see more of the beach 110 and more objects that might appear on the beach 110. A user might pan upward, downward, or to the right to see more of the water 120 and more objects that might appear on the water 120. A user might also zoom in and out to cause objects to appear nearer or farther. Zooming in might cause previously invisible objects or properties of objects to come into view.
By selecting objects in the virtual world 100, a user can cause various actions to occur. For example, the mountain 112 or some other object might be a shortcut to an application such as a game, an address book, a calendar, an email program, personal information management, business applications, or some other common handset application. Using the handset navigation keys or another input mechanism to select the mountain 112 might launch the application associated with the mountain 112. Selection of the building 114 or some other object might, for example, cause a screen to be displayed that allows the settings of the handset, such as ring tones or other preferences, to be adjusted.
In addition, a plurality of applications might be associated with a single object. Selecting such an object, the tree 116 for example, might cause a menu of shortcuts to the applications or some other type of display of options to appear in or on the virtual world 100. The user might then select one of the shortcuts or options.
Alternatively or additionally, a plurality of shortcuts and/or options related to a plurality of applications might be visible in or on one of the objects before the object is selected. For example, a plurality of shortcuts might appear as a plurality of fruits on the tree 116. The user might be allowed to directly select one of these shortcuts instead of first selecting the tree 116. The user might be able to zoom in to the tree 116 to view the shortcuts more closely or to bring additional shortcuts into view.
Selection of another object might give the user the appearance of moving to that object. For example, selection of the island 122 might cause the user to appear to fly over the water 120 and land on the island 122. The island 122 might then expand and become another virtual world. That is, island-related objects not previously visible in the beach scene might appear to be present on the island 122. Selection of an object on the island 122 might cause any of the actions described in relation to the beach scene to occur.
The objects in the virtual world 100 might alert the handset user about events for which the user wishes to be notified. For example, movement of the airplane 130 or the boat 124 within the virtual world 100 might be an indication that a message, a time for an appointment, a news update, or some other type of information has arrived. The airplane 130 might carry a banner 132 or the boat 124 might have a sail 126 or flag that contains text or some other type of indication of the content of the information that has arrived. For example, the sail 126 or the banner 132 might display the sender and/or subject of an email or might display the name of a person with whom an appointment was made when the time for the appointment arrives.
Other types of information could be conveyed by other types of movements or changes in the virtual world 100. For example, the position of the sun 140 or the hands of a clock might indicate the time of day. The current weather conditions at the user's location might be indicated by the weather depicted in the virtual world 100 and the virtual world's weather might change as the local weather changes. For example, if rain is falling at the user's location, rain might appear to fall in the virtual world 100.
Alternatively or additionally, a previously invisible object might become visible or a previously visible object might change its appearance to act as a notification that an event has occurred. For example, a bottle 128 depicting a message in a bottle could appear to wash up on the shore of the beach 110 to indicate that an email, a text message, or some other type of message has arrived. Or, an object might flash, change color, rotate, or otherwise change to indicate that an event has occurred. Selecting the object that appears or changes its appearance might retrieve a message or perform some other action related to the notification. Other types of information that could be signaled or represented by movements or changes in the appearance of the virtual world 100 will be apparent to one of skill in the art.
FIG. 2 illustrates an embodiment of another virtual world 200 that might appear as a home screen on the display of a handset. In this example, a city scene is depicted in which a plurality of city-related objects are present, including a plurality of buildings 210, a landmark 220, a street 230, and an automobile 240. As with the beach-based scene, selection of an object in the city scene can cause various actions to occur. For example, selection of building 210a might launch a first application and selection of building 210b might launch a second application. Alternatively, selection of building 210a or some other object might cause the appearance of a menu or of another object, either of which might allow other actions to be taken. In another alternative, selection of one of the buildings 210 might cause the user to appear to enter the building 210. The user might then be able to navigate through the rooms of the building 210, each of which might allow the user to take actions or might provide information to the user.
Also, as with the example of the beach scene virtual world 100, movements or changes in the city scene virtual world 200 can provide notification of an event to a user. For example, movement of the automobile 240 along the street 230 might be a signal that a message has arrived. Alternatively, sounds might be used to indicate the arrival of a message or the occurrence of some other event. For example, the sound of the automobile 240 blowing its horn or the sound of the driver of the automobile 240 shouting a message might indicate that an email has been received. Also, the number of automobiles 240 on the street 230 might be indicative of actual traffic conditions.
One of skill in the art will recognize that many other virtual world scenes containing many other types of objects could be used in a similar manner. Also, the virtual worlds need not necessarily represent real scenes. For example, readily identifiable or well-known scenes from movies (such as Star Wars®), television programs (such as Star Trek®), games, books, or other media could be depicted. Alternatively, a fantasy scene that exists only in the mind of the creator of a virtual world could be depicted. Also, it should be understood that the beach scene virtual world 100 and the city scene virtual world 200 were illustrated in a very crude fashion in FIGS. 1 and 2. In actual use, it is anticipated that the virtual worlds would have a high-quality appearance so that the user would have the impression of viewing a realistic scene.
In an embodiment, a handset that is capable of displaying a virtual world as a home screen as described herein may include a virtual world player component that enables the display and operation of the virtual worlds. The same player can be installed in multiple different handsets and can be capable of displaying multiple different virtual worlds. In one embodiment, multiple virtual worlds can be stored in the memory of a handset and the user can select which virtual world the player will display at a given time. Alternatively, only one virtual world at a time might be stored. If the user wishes to change virtual worlds, the user might download or otherwise acquire a different virtual world, install the new virtual world on the handset, and have the player display the new virtual world.
Once a virtual world has been selected and/or installed, the user may be given the capability to customize the virtual world by selecting which objects will perform which actions. For example, returning to FIG. 1, the user might select whether the airplane 132, the boat 124, or the message in a bottle 128 will appear in the virtual world 100 to indicate that a new message has arrived or that some other event has occurred. Alternatively, the user might select a sound to indicate the arrival of new information. Also, the user might be allowed to create objects to insert into a virtual world and might be able to assign actions to the created objects.
The user might also select which objects will be used as application shortcuts and might use mnemonic devices to remember the selections. For example, in FIG. 2, a photograph viewing application might be associated with the landmark 220 and an address book application might be associated with a telephone booth 250. The user might elect to associate a group of related application shortcuts under a single object so that, when the object is selected, a list or other display of the shortcuts appears. The user might also be able to associate an icon and/or text with an object as an aid to remembering the function of the object.
The user might also be able to customize the weather that appears in a virtual world. For example, the weather shown in a virtual world might depict weather events that are actually occurring at the user's current location. Alternatively, the user might choose to have the virtual world depict the weather in a different location or to have the virtual world weather be unrelated to any real weather. Other types of customization for a virtual world will be apparent to one of skill in the art.
While the discussion herein has focused on the display of virtual worlds on handsets, it should be understood that similar considerations could apply to other devices. For example, virtual world players could also be installed on desktop computers, laptop computers, and other devices with displays so that the devices could display virtual worlds that function as described herein.
