This description relates to user interfaces, and more particularly to generating customized graphical user interfaces for mobile computing devices.
Handheld mobile devices, such as cellular telephones and personal digital assistants (PDAs), are becoming increasingly powerful both in terms of processing power and the ability to provide access to data. The usefulness of these enhancements is often limited, however, by an inability of mobile devices to display data effectively due to the small size of the display, to the limited bandwidth available for wirelessly delivering data, and to mobile device's limited memory resources relative to laptop and desktop computers.
There are beginning to be some applications that are specifically designed for handheld mobile devices. Many such applications are based on application development platforms also specifically designed for mobile devices, such as Java 2 Platform Micro Edition (J2ME) and Binary Runtime Environment for Wireless (BREW). Some applications that are designed for retrieving data from a remote location to a handheld mobile device are browsers that correspond to conventional browser applications in that they enable users to enter uniform resource locators (URLs) to retrieve information from any internet web site. Other applications enable data to be retrieved by launching a separate browser application in response, for example, to selecting a hyperlink in a user interface. In addition, specialized, limited functionality applications are available that provide a mechanism to access data from dedicated application service providers.
One useful application for mobile devices is that of “local search.” Such an application allows a user to specify a particular geographic location or area when submitting a search so that the search results relate to that location or area. For example, a user may enter “dim sum restaurants 56523” to be provided a list of all dim sum restaurants in the 56532 zip code. Or the user might submit “hotels near LAX” to receive a list or map showing all hotels near Los Angeles International airport. Such local search can be particularly helpful to users of mobile devices because they are often looking for information about things around them, e.g., attempting to find directions, from their car, to a particular store or building. Thus, there is a need for computer programs or interfaces that provide users with convenient access to information and useful presentation of that information.
In general, this document relates to methods and systems for allowing users of mobile devices having, for example, relatively small screens and slow data transmission rates (or high latency) to interact with those devices in a convenient and helpful manner. As one example, a user can be provided with convenient approaches for panning and zooming a view such as a map. The user may also be provided with techniques for displaying and interacting with local search results. Moreover, the user may be provided with techniques for generating directions for a travel route, and for interacting with the direction information.
In one implementation, a computer-implemented mapping method is disclosed. The method comprises displaying a first map view of a geographic area on a display of a computing device, receiving a voice or key-press zoom command and generating a first zoom box of a predetermined size on the display relative to the first map view in response to the zoom command, and displaying a second map view of a zoomed geographic area corresponding to the zoom box. The second map view may have a different resolution than the first map view. Also, the first and second map view may be comprised of tiles of raster images.
In some aspects, the method further comprises retrieving tiles of the zoomed geographic area and replacing the display with the retrieved tiles. The second map view may be a zoomed-in view of the first map view. Also, the zoom box may comprise an outline superimposed inside the edges of the first map view. The zoom command may also be received by activation of a key on a telephone device. In addition, the method may comprise receiving a movement key activation and panning the zoom box over the first map view in a direction corresponding to the activated movement key. The activated key may comprise a key aligned with a changeable region of a display on the computing device.
In other aspects, the second map view may be a zoomed-out view of the first map view. The zoom box may also comprise the first map view displayed as a reduced image centered in the display. In addition, a display area around the reduced image may comprise a featureless background. In other aspects, the method may further comprise generating a second zoom box on the second map view and displaying a third map view of a zoomed geographic area corresponding to the second zoom box.
In another implementation, the document discloses a tangible media carrying instructions that, when executed, perform certain steps. The steps may include displaying a first map view of a geographic area on a display of a computing device, receiving a voice or key-press zoom command and generating a zoom box of a predetermined size on the display relative to the first map view in response to the zoom command, and displaying a second map view of a zoomed geographic area corresponding to the zoom box. The steps may further comprise retrieving map tiles, each map tile representing a portion of the zoomed geographic area, and replacing the display with the retrieved tiles. In addition, the zoom box comprises an outline superimposed inside the edges of the first map view.
In yet another implementation, a mobile computer-implemented mapping system is disclosed. The system comprises an interface to receive location information and to provide, in response, corresponding map information, map tile storage holding a plurality of tiles for display with the interface, and means for changing map information displayed by the interface in response to inputs by a user to a mobile device.

Like reference symbols in the various drawings indicate like elements.
When a user selects to pan the map in a particular direction, the map may be regenerated in a number of ways. As one example, the map may be comprised of a number of pre-composed tiles that are in the form of raster images. A displayed map may be made up of the tiles around the center of the map sufficient to fill the display and perhaps extend somewhat beyond the display. The device may then move these tiles in unison when a user requests a pan, so that the full image of the map moves smoothly. The panning motion for each press of a key may be indexed to a particular distance, such as a single row of tiles or a portion of a row of tiles.
If the user pans beyond the extent of available tiles, the map may be temporarily displayed with the area for those tiles blank, as shown in view (b) in
In addition, by using tiles, panning may occur through methods other than simply erasing a prior map and replacing it with a wholly new map that has “jumped” over a predetermined distance. For example, when a user moves a certain direction, crosshairs that represent the desired location—typically the center of the map—may jump to the new panned-to location, and the map may then slide smoothly (e.g., in an animated manner) over until the cross hairs are again in the middle of the display. During or after the adjustment, additional tiles may be downloaded or loaded from a cache as necessary.
Smooth map scrolling may also occur by moving the map as long as a user holds down a directional button rather than having the map jump in large increments. The speed of the pan may be pre-set, set by the user, or may be a function of how long the button has been held down (with faster panning the longer the button has been held down, either as a step-function increase in speed, a linear increase in panning speed, or some other functional relationship of speed to time-held). Panning may also occur by moving the map in larger incremental jumps (i.e., to the new location), with the crosshairs staying in the middle of the display. For flexibility, the type of scanning may be selected, such as based on a device performance rating (e.g., fixed when the device or application is deployed), an option available to the user, or set dynamically based on measured performance.
Additional tiles may also be downloaded around those displayed on a map and cached in local memory on the device. In this manner, a user can pan around an initial image to a limited extent without forcing the download of additional tiles. In other words, the amount of map display stored on a device may extend beyond the edges of the actual display so that small motions can be conducted without the need for downloads, and also so that more of the map can be seen by the user even before additional tiles are downloaded.
The tiles may also differ from each other based on the zoom level at which a user is viewing the map. In particular, an entire map, e.g., of the United States, may be displayed using multiple layers of tiles. The highest layer would have very few tiles, which might simply be rendered with state lines on them. At a closer zoom level, regional details such as counties or interstate highways may be shown, and additional tiles will likewise be provided. At a closer level that may involve thousands or millions or more of tiles, individual streets may be shown. Each layer may have its own set of tiles, rendered at a particular resolution for the map, with each closer level having more resolution and more tiles.
The display may be generated using dynamic download of map tiles, and caching of tile information. Such an approach is disclosed more fully in co-pending U.S. application Ser. No. 11/051,534, which is herein incorporated by reference in its entirety.
Also,
The maps provided for display on a mobile device may differ from those normally provided to full-featured desktop computers. For example, because mobile displays generally have a limited display area, street names and other identifiers may be repeated more often to ensure that they will be shown on a smaller display. In addition, different colors may be used to accommodate displays having lesser color depth than those of full-featured computers.
a-2b show displays for a zooming operation on a mobile device. A map may be displayed initially at a particular zoom level that may be preset, determined by the device, or determined by a remote system, such as a server that stores and provides tiles in response to requests from devices. For example, where a search is a local search that includes a zip code or area code, the zoom level may be selected so that the area displayed with the map approximates the reach of the area code. Also, where a map is returning search results, the zoom level may be set just wider than the extent of the search results, so that all results can be seen, but the results are as zoomed-in as is practical.
A user may then zoom in or out on the display, such as a map. In
As shown in view (a) of
A user may also move the zoom box around the display, such as by using directional keys (e.g., the control pad or the 2-4-6-8 keys). For example, if a user wants to zoom in on a small area in the upper right-hand corner of a currently-displayed map, the user may first press a “zoom in” key as many times as the user prefers, and then may press “right” and “up” directional keys to move the zoom box over the desired area. Such movement may occur in jumps or as smooth panning of the zoom box, e.g., by animating movement of the zoom box an index distance each time a directional key is pressed.
A user may begin the process of displaying the zoomed-in display by pressing an appropriate execution key. For example, the user may press the middle of the selection key. In addition, the regeneration process may be triggered by a delay, such as the passage of several hundred milliseconds after a user has last pressed a zooming-related key.
To make the zooming appear relatively smooth, the image may be regenerated in a number of ways. For example, the portion of the image inside the zoom box may be initially expanded to fill the entire display, but in less-than-desired (but perhaps smoothed or anti-aliased) resolution. The user may then be provided the opportunity to view this image while more detailed information is retrieved for the zoomed-in display. The more detailed information may include tiles providing a closer view of the portion of the prior map.
The transition from the original map to the zoomed-in map may occur by any appropriate mechanism. For example, the original, lower-resolution portion of the initial map may be shown across the display, or may be gradually increased in size (with appropriate anti-aliasing or other up-converting technique to compute the appropriate pixel values at each size of the image) until it is shown across the display. Once it has taken full size, the more detailed image may begin to replace it, such as by overwriting with scattered pixels from the more detailed image until the whole image is displayed, or through other known approaches to transitioning from lower-resolution to higher-resolution images. In addition, map information may be layered, so that a map image is added at a different time or a different rate than are street names and other similar map labels.
Zooming out may occur in a manner similar to that of zooming in, and is shown in views (d) through (f). When the user selects a “zoom out” key, the map being displayed (view (d)) may be made smaller in size with blank space around it (view (e)). If the user presses “zoom out” again, the image may become smaller yet, to a maximum distance of zooming out. Also, if the user then presses a “zoom in” key, the image may get larger until it fills the display, and the device may then show zoom boxes as rectangles of decreasing size on the map. View (f) shows the result of zooming out one degree from the display of view (d).
Though not shown, the user may also move the zoom box for zooming out, so that the new display is not based on the same center point as the old display. Specifically, directional keys may be used to move the box, which may take the form of an outline, as with the zoom box for zooming in. When the box is moved a particular direction after a zoom out key has been selected, the image may be left centered on the screen (as in view (e)), but the outline may move around the image and into the blank space around it. If the device contains image data for such an area (e.g., the remainder of image tiles around the edge of the initial display), that data may be displayed as the zoom box moves. Also, lower-resolution around the edge of the initial display may also be shown.
The blank area around the display may take on a variety of forms. For example, it may be a simple solid color for simplicity. It may also be a “background” or “wallpaper” image, so as to provide the user with the sense that the image is simply layered on top of the device's standard desktop, such as in the form of a simple widget. In addition, the area may be provided with logos or other promotional material, including material relevant to the location being shown, and may be displayed as part of a program such as the known AdWords or AdSense programs from Google.
The zoomed-out display may be generated from the initial display in manners similar to that for the zoomed in display above. For example, the initial, but shrunken, view may be first displayed, including in a lower resolution than originally displayed, and new images (e.g., in the form of tiles) may be padded around it as they are received. The initial view may stay in the middle, or may ultimately be replaced by a new image for that area, so as to better coordinate with the new images around it (e.g., if street names or other labels are provided in different locations for different zoom levels).
a-3b show displays for a local searching operation on a mobile device. Searching on the device may employ a standard search system on a server, such as the Google Local service. The information retrieved may be specially formatted for mobile display, such as by a webserver connected to the search backend, but configured to provide information particularly well-suited for display on a mobile device (e.g., search results responsive to a query, but relating to a particular town or zip code). View (a) in
The user may enter a search request by selecting the “type a new search” hyperlink from the initial view (view (a)), which causes the device to show an empty search input box (not shown). The user may enter a search request that includes location information, such as a zip or area code or other information such as “hotels near jfk” or “pizza in sf.” In such a situation, the server that receives the request will parse out and identify the location information, and the search will be conducted around that location. The user may also enter a search request without location information, such as “dim sum,” “flowers,” or “U Haul.” In such a situation, the local search may be performed on the area shown on the map when the search is performed, or may be based on a centerpoint that is the centerpoint of the map (but perhaps covering an area smaller or larger than that shown in the map). In addition, a location may be assigned for a user to be applied across all searches, or a location may be determined by the device, such as through GPS measurement. The search box may be incorporated directly into the search dialog box also.
A user may then submit the search request, such as by pressing the equivalent of an “enter” key (e.g., pressing the center of a control pad). The request, with appropriate identifying and other information, may then be transmitted to a remote system, such as a local search server system. That system may recognize the request as coming from a mobile device, and may format the information accordingly, but may otherwise perform the search as any other local search. For example, the system may return information for nine hits so as to correspond to selections that may be made using the nine positive integers on a typical telephone keypad. (A tenth result may be provided for the 0 key also).
Such search results are shown in view (b) of
Each pin is also given a number that is associated with a key on the keypad. Pressing the associated key once will cause summary information for the search result to be displayed, such as the business name, as shown in view (b). The zoom level may be selected so as to avoid getting more than 9 or 10 results, which could not be easily identified with a mobile device keypad. Where additional results exist outside the bounds of the display (e.g., because there are many results or because the user was zoomed in very tightly and display of the search results did not change the zoom level), other selections may be provided to the user for viewing other search results, such as is shown in view (b). Various actions may be taken on the information. For example, a user may press the “send” or similar button on their device to make a telephone connection with the search result-a click to dial transaction.
Also, with mobile devices having small sizes and a limited number of input keys, it may be preferable only to display a smaller number of results on a map at a time to provide for easier viewing and interaction by a user. Where there are additional “hits” in the area searched, the display may provide some indicator of the presence of those hits located off the initial display. For example, an icon (not shown) could be displayed at each edge of the display where there are additional hits off that side of the display. Likewise, icons may be shown in the corners when the hits are located diagonally from the displayed initial map (e.g., providing eight directions of possible indicators).
The icons may be similar to the pins that represent hits on a full desktop display, such as for a desktop computer. For example, the icons may simply be circles like the pins, but without extensions below them toward the map, so as to indicate that they represent hits just as the pins represent hits, but that they are not located over their respective hits. The icons may also take on a different color than the pins so as to distinguish them, may be provided with additional indicators such as arrows attached to or wrapped around the pin heads, and may also be provided with a number that may or may not correspond to a key on the device's keypad. For example, the number may correspond to the number of hits located in the direction of the icon. As such, the user may be apprised that panning in a particular direction is more likely to be successful than panning in another direction. Such additional direction may be particularly valuable to a user of a mobile device because such a user may not be able to see very much at one time, and may also have much less bandwidth, so that the user has a need to pan more often but more efficiently also.
Movements with the device may also occur in a manner that appears to a user as animated. For example, tiles may be moved smoothly across a display from one panning position to another or from a small zoomed-out or zoomed in display to smoothly enlarge to the post-zoom display size. In addition, when search results are provided, panning toward a result may cause the display to snap to the next result, either immediately upon entry of a pan command, or when the result is sufficiently close to entering the edge of the display. Moreover, as a user selects different numbered search results, the display may automatically pan smoothly from one result to the next, e.g., placing the new result in the center or near the center of the display.
The user may also press the key relating to a search result a second time (or another key, as prompted) to bring up additional information about the result, as shown in view (c). Such information may include an address of a business along with its telephone number and other contact information. Again, the telephone number may allow for click-to-dial operations-either by highlighting the number or a “call” hyperlink on the display and selecting it, or by pressing a “send” or similar button when the result is displayed.
Additional choices may also be presented to the user. For example, the user may be provided with options whose selection permits the user to receive directions to the location of the search result or from the location of the search result. The other endpoint for the directions may be selected in any appropriate manner. For example, where the mobile device is GPS-enabled or otherwise location-enabled, the directions may be computed automatically from a measured location of the device. Alternatively, the user may be asked to enter their current location, and the directions will be provided between the entered location and the location of the search result. Also, particular locations may be stored in a history list, and may thus be selected easily by a user. Additional information about a search result may also be shown, and additional options may be provided for selection by a user.
View (d) shows a subsequent search on the device, where a search history is stored. The display is similar to that in view (a), but now a recent search is available for display in a search history. Thus, a hyperlink for the search “pizza” appears on the display. This history may be helpful, for example, because it allows a user to do the same search but for different areas. For example, a traveling salesperson may love a particular restaurant chain, and may place the name of that chain into favorites. The salesperson may then repeat that search easily for any town in which the salesperson is located, and may quickly receive results to the search (particularly when an automatic location identifier generates the appropriate map). When a user selects an item from the search history, the user may be provided an opportunity to edit the item. If such editing occurs, the edited search request may be added to the history list.
b shows similar searching processes with more detail. In a first view, a map is displayed. A user then selects a right softkey associated by position with the “menu” overlay. Upon selected the softkey, a menu of choices is generated visually over the map, with a portion of the map show through around the menu, so that the display more accurately approximates a desktop windowed system with which users are typically aware. The user selects “1” and is provided a search box in the third view (and the menu box is removed). The box shows recent searches that the user may enter simply by using a directional key to move down to one of the searches, and then press an activation button. The user may also choose to type a new search using a URL selection or such an option.
In the example, the user enters “pizza 02138,” a query that may be transmitted to a central server. The server will parse the query apart and look for local information in it. For example, the system may assume that a 5-digit number in the appropriate location of a query represents a zip code. The system may also assume that food names, when accompanied by location information such as a zip code, represent an interest in restaurants. Once the user confirms their query, such as by pushing the center of a directional button, the query may be submitted to the central server, and the results sent back. The next view shows an exemplary display for such a result. As shown, a single result has been generated in response to the search query, and it is a particular pizza parlor.
The user may be given the option to see additional detail about the search result (e.g., by pressing a key such as 1), and such detail is shown in the last display in
a-4b show displays for a directions operation on a mobile device. Directions may be, for example, a choice under a “menu” item, along with other options like those just discussed. As just noted, a directions operation may also be readily selected from the outcome of a local search request. Directions may be shown by a line of contrasting color or weight overlaid on a map, and may also include a number of waypoints, where the illustrated path changes directions or changes from one road to another road. Other waypoints may also be provided, such as lookouts or other points of interest along a path. A user may be provided with a menu to select preferences for particular waypoints that the user would like to have displayed near a route, such as particular stores, government buildings, landmarks, scenic points, etc.
View (a) in
Once the user has entered the starting point, he or she may enter the ending point in a similar manner to the entry of the starting point. View (b) shows a dialog for entering end point information. Note again that the device may track recently identified locations and present them as “recent places” selections, either for starting points or ending points, to permit quicker identification of a point by a user. Also, context sensitive softkeys may also be provided, such as an option (in view (a)) to cancel an attempt to receive directions, and an option (in view (b)) to go back to re-select a start point.
Once the start and end points are provided, the remote system (such as a Google backend server) may compute a route and transmit it back to the device for display. The route may be placed over the map in a particular color, with identifiers for the start and end points. For example, the start point may be a simple green icon, while the end may be a red icon. Also, the path may be in the form of a highlighted or thickened line over the suggested paths.
A dialog can initially be displayed along with the proposed directions. The dialog (see view (c) in
A user can use the keypad (or voice commands, or even GPS readings) to traverse through the route turns, with navigational information appearing in a pop up window in much the same way as the route overview information. A user may move forward and back through a route, for instance, by pressing the 3 and 1 keys, respectively (as shown in the bottom display of
The map may additionally animate with the actual progress along a path as a user moves from turn to turn. For example, the text indication for a waypoint may jump from one waypoint to the next, but the tiles may be panned smoothly so that a first waypoint is initially positioned near the middle of the screen and then a second waypoint is moved onto the screen (if it is initially off the screen) and then into the middle of the screen. Appropriate tiles may be retrieved, in a tile-based system, to show the map between the two waypoints. Also, the map may rotate so that the user's course on the map is always view-northward (i.e., to the top of the device).
When a map is moved, the device or the remote system with which the device is in communication may set an appropriate initial level for the map. For example, where the address is a simple street address, the zoom level may be very close. When the address is as broad as a zip code, the zoom level may be selected so as to substantially match that area.
a is a flow chart 600 showing actions for zooming and panning a graphical display on a mobile device. The flow chart 600 shows actions that may occur like those for rendering the views shown in
With the map displayed to a user, the user may be provided with a number of options for interacting with the map. In this example, three distinct map movement options are illustrated. A first option involves panning the map, a second option involves zooming in on the map, and a third option involves zooming out on the map.
In the first, panning, option, a user makes a selection to pan (box 608). The selection may involve, for example, pressing on one side of a directional key, or by pressing an appropriately numbered button on a telephone keypad. Such selection may cause the map to immediately move one indexed position in the direction selected (box 610). The selection may also cause the mobile device to make a request for additional tiles to fill in the new space (box 612). That new space may be a blank area on the screen or a blank area off but near the screen, such as where tiles around the screen have previously been loaded, and the pan then requires additional tiles around the newly displayed screen to be loaded in anticipation for another pan selection. Where appropriate, any newly fetched tiles may be added to the display. The fetching of tiles may also be delayed, such as to wait for a regeneration selection from a user. Such an approach may be appropriate, for example, where there is a per-communication charge for a system or where latency is large so that a single transmission is preferred only after a final decision has been made about the appropriate location for the pan. At box 630, the user is then provided an opportunity to pan again or to carry out other actions.
The second option—zooming in—occurs in response to a “zoom in” command (box 614), which may be sensed, for example, from the pressing of the center of a directional key. Upon receiving the command, a zoom box outline may be drawn over the map, such as in an area circumscribing a predetermined portion in the center of the map and having a shape that matches the shape of the overall display (box 616). The regeneration of the map at the zoomed in resolution may again occur after identification of a zoomed in level, or may await an explicit command for regeneration from the user (box 618). The regeneration, when it occurs, may happen by replacing the prior tile with new, higher resolution, tiles as the new tiles are retrieved (box 620). (The tiles may be higher resolution in that they could have more pixels, or they may have the same number of pixels, but may show less area and more detail because they show only a zoomed in view). To make the transition smoother, the original tiles may initially be upscaled, and may then be replaced with new zoomed in tiles, so that initially, a slightly blurred version of the view is shown, and is then replaced with a sharper version. Again, with the new view of the map displayed, the user may be given the opportunity to make other selections.
In the third option—zooming out—a user again starts the process by making a zoom out selection, which may occur, for example, by pressing an appropriately configured softkey, as shown above (box 622). The user's device may immediately re-render the existing tiles at a reduced size in a zoom box (as shown above), such as by removing pixels from the original tile images (box 624). Again, the activation of the zoom process may occur immediately or otherwise automatically, or may await explicit activation by the user (box 626). When the zoom is activated, the device may cause a central server to select from storage appropriate tiles at the new zoom level, and to deliver the tiles to the device for subsequent display of the tiles (box 628). The display may again be smoothed such as by gradually replacing the existing reduced tiles, with the new tiles.
b is a flow chart 636 showing actions for displaying menus on a mobile device. The flow chart 636 shows actions that may occur like those for rendering the views shown in
With the map displayed, a user may make a selection to have a pop over menu displayed on top of the map (boxes 644, 646). The menu may provide the user with a variety of choices. Here, each choice is indexed to a key on a telephone key pad for easy entry by a user, and is shown in flow chart 636 by a numbered circle. The first selection is “search,” which will cause the search box shown in
Other selections involve lesser interaction with the user. For example, selection of the fourth option, “satellite/map view,” causes the form of information displayed in the map to change to a satellite photo if it is presently a map, and vice-versa (box 654). The label in the menu for this selection will also alternate to the choice that is opposite to what is currently displayed in the map when a selection occurs. Selection of the seventh option, “help,” will cause a help menu to be displayed (box 658) in a well-known manner, which may include a searchable index of help topics. Likewise, selection of the eighth option, “quit,” will return the device from the mapping application or function to its standard functions (box 660).
c is a flow chart 662 showing the display of local search results on a mobile device. The flow chart 662 shows actions that may occur like those for rendering the views shown in
Upon receiving the results, the user's device may display the results over the existing map, or may generate a new map if the results correlate to a different area. The display of the results may, to minimize clutter on the map, involve displaying icons representative of each result at or near the location of the result, if the location can be determined. Each icon may be provided with a label that corresponds to a key on the device, such as the numbers 1-9 or 0-9 for a cellular telephone (box 670). Such a correlation may make selection of one or more results for further review much easier for the user. At box 672, a user selects a numbered button corresponding to one of the displayed search results, and detail about the result is displayed, such as in a bubble pointing to the result icon.
At box 674, a user further makes a selection to see additional information about the particular result and/or to have access to selections for taking action with respect to the result. For example, the user may be provided with a clink-to-call link or icon (box 676), whose selection may cause the device to place a telephone call to a telephone number associated with the search result (box 678). The user may also choose to have directions generated from their current location (e.g., the center of the map) to the particular result (box 680). The user may also choose to conduct a new search or to edit the existing search (box 682).

A location resolver 712 in mapping server 708 may receive information such as an English-language address, parse the address, and convert it to a location in a common format, such as GPS coordinates. The location resolver may then communicate with a map generator 714, which may be configured to determine which tiles, of various tiles stored by system 700, to be displayed by device 702. For example, map generator 714 may determine an appropriate zoom level for a map and may determine which tiles associated with that zoom level are needed for a proper display of the map. Map generator 714 may then make a request to tile selector 718 for the needed tiles. The tiles may be stored, for example, in a full tiles database 720 and a mobile tiles database 722. Such storage may allow the various components of mapping server 708 to serve both mobile and desktop clients as is needed. Information such as header information may be analyzed to determine if a client is mobile or non-mobile. Similar information can be provided from both forms of clients (e.g., the location information and requests may be formatted in similar manners) so that the same modules may server both to the extent possible.
Map generator 714 may also be in communication with search engine 716, and may receive information, such as local search results, from search engine 716. The search results may also include location information associated with each search result, so that map generator 714 may generate an icon to be overlaid on a map in the correct location for the result. In addition, map generator may reformat textual information for each search result, such as by selecting information for balloons to be displayed with each result, and formatting the information appropriately.
The search engine 716 may draw on a number of databases in providing information to the device 702, either directly or through map generator 714. For example, the search engine 716 may provide a search on one or more corpuses of documents, such as stored in corpus database 726. The corpuses may be divided in several manners, such as separate corpuses for web search, local search, image search, blog search, shopping search, book search, and the like. To increase the efficiency of searching, an index database 728 may be provided to serve as an index of the documents in one or more corpuses. In addition, an ads database 724 may also be provided, and may be accessed by search engine 716 to produce advertisements that relate to entered search queries. Such advertisements may be delivered with mapping information and/or with search results, and may be displayed as appropriate on device 702.
Computing device 800 includes a processor 802, memory 804, a storage device 806, a high-speed interface 808 connecting to memory 804 and high-speed expansion ports 810, and a low speed interface 812 connecting to low speed bus 814 and storage device 806. Each of the components 802, 804, 806, 808, 810, and 812, are interconnected using various busses, and may be mounted on a common motherboard or in other manners as appropriate. The processor 802 can process instructions for execution within the computing device 800, including instructions stored in the memory 804 or on the storage device 806 to display graphical information for a GUI on an external input/output device, such as display 816 coupled to high speed interface 808. In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple computing devices 800 may be connected, with each device providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system).
The memory 804 stores information within the computing device 800. In one implementation, the memory 804 is a computer-readable medium. In one implementation, the memory 804 is a volatile memory unit or units. In another implementation, the memory 804 is a non-volatile memory unit or units.
The storage device 806 is capable of providing mass storage for the computing device 800. In one implementation, the storage device 806 is a computer-readable medium. In various different implementations, the storage device 806 may be a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. In one implementation, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described above. The information carrier is a computer- or machine-readable medium, such as the memory 804, the storage device 806, memory on processor 802, or a propagated signal.
The high speed controller 808 manages bandwidth-intensive operations for the computing device 800, while the low speed controller 812 manages lower bandwidth-intensive operations. Such allocation of duties is exemplary only. In one implementation, the high-speed controller 808 is coupled to memory 804, display 816 (e.g., through a graphics processor or accelerator), and to high-speed expansion ports 810, which may accept various expansion cards (not shown). In the implementation, low-speed controller 812 is coupled to storage device 806 and low-speed expansion port 814. The low-speed expansion port, which may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet) may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter.
The computing device 800 may be implemented in a number of different forms, as shown in the Figure. For example, it may be implemented as a standard server 820, or multiple times in a group of such servers. It may also be implemented as part of a rack server system 824. In addition, it may be implemented in a personal computer such as a laptop computer 822. Alternatively, components from computing device 800 may be combined with other components in a mobile device (not shown), such as device 850. Each of such devices may contain one or more of computing device 800, 850, and an entire system may be made up of multiple computing devices 800, 850 communicating with each other.
Computing device 850 includes a processor 852, memory 864, an input/output device such as a display 854, a communication interface 866, and a transceiver 868, among other components. The device 850 may also be provided with a storage device, such as a microdrive or other device, to provide additional storage. Each of the components 850, 852, 864, 854, 866, and 868, are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate.
The processor 852 can process instructions for execution within the computing device 850, including instructions stored in the memory 864. The processor may also include separate analog and digital processors. The processor may provide, for example, for coordination of the other components of the device 850, such as control of user interfaces, applications run by device 850, and wireless communication by device 850.
Processor 852 may communicate with a user through control interface 858 and display interface 856 coupled to a display 854. The display 854 may be, for example, a TFT LCD display or an OLED display, or other appropriate display technology. The display interface 856 may comprise appropriate circuitry for driving the display 854 to present graphical and other information to a user. The control interface 858 may receive commands from a user and convert them for submission to the processor 852. In addition, an external interface 862 may be provide in communication with processor 852, so as to enable near area communication of device 850 with other devices. External interface 862 may provide, for example, for wired communication (e.g., via a docking procedure) or for wireless communication (e.g., via Bluetooth or other such technologies).
The memory 864 stores information within the computing device 850. In one implementation, the memory 864 is a computer-readable medium. In one implementation, the memory 864 is a volatile memory unit or units. In another implementation, the memory 864 is a non-volatile memory unit or units. Expansion memory 874 may also be provided and connected to device 850 through expansion interface 872, which may include, for example, a SIMM card interface. Such expansion memory 874 may provide extra storage space for device 850, or may also store applications or other information for device 850. Specifically, expansion memory 874 may include instructions to carry out or supplement the processes described above, and may include secure information also. Thus, for example, expansion memory 874 may be provide as a security module for device 850, and may be programmed with instructions that permit secure use of device 850. In addition, secure applications may be provided via the SIMM cards, along with additional information, such as placing identifying information on the SIMM card in a non-hackable manner.
The memory may include for example, flash memory and/or MRAM memory, as discussed below. In one implementation, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described above. The information carrier is a computer- or machine-readable medium, such as the memory 864, expansion memory 874, memory on processor 852, or a propagated signal.
Device 850 may communicate wirelessly through communication interface 866, which may include digital signal processing circuitry where necessary. Communication interface 866 may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through radio-frequency transceiver 868. In addition, short-range communication may occur, such as using a Bluetooth, WiFi, or other such transceiver (not shown). In addition, GPS receiver module 870 may provide additional wireless data to device 850, which may be used as appropriate by applications running on device 850.
Device 850 may also communication audibly using audio codec 860, which may receive spoken information from a user and convert it to usable digital information. Audio codex 860 may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of device 850. Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by applications operating on device 850.
The computing device 850 may be implemented in a number of different forms, as shown in the Figure. For example, it may be implemented as a cellular telephone 880. It may also be implemented as part of a smartphone 882, personal digital assistant, or other similar mobile device.
This document describes features of a user interface related to local search processes, which may be implemented in J2ME, BREW, or another applicable language or environment, such as PocketPC. In addition, although the Figures show a simple map display, the actual map may differ from that shown. For example, satellite images for comparable geographic areas may be shown instead of the map. Also, a “hybrid” display may be used, where the background is satellite images, with an overlay of streets in particular drawn colors with labels.
Also, the images displayed for mobile devices may be altered from those shown on full-featured computers. In particular, because the screens on mobile devices are generally smaller than those on full-featured computers, labels (such as street names laid over the corresponding lines that represent the streets) may be repeated more often for mobile images to ensure that the labels appear on the smaller mobile displays.
The remote system may be configured so as to recognize requests from mobile devices and to respond accordingly. For example, header information in the requests may identify certain devices as mobile, and the system may use that information to route the requests to certain web servers or to employ certain formatting in a web server. For example, a system may select different tiles having more frequently repeating label information for mobile devices, as explained above. The system may also format the information using a mobile format such as WML, iMode, or xHTML.
The systems and all of the functional operations described in this specification can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structural means disclosed in this specification and structural equivalents thereof, or in combinations of them. The techniques can be implemented as one or more computer program products, i.e., one or more computer programs tangibly embodied in an information carrier, e.g., in a machine readable storage device or in a propagated signal, for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor, a computer, or multiple computers. A computer program (also known as a program, software, software application, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file. A program can be stored in a portion of a file that holds other programs or data, in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.
The processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform the described functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).
Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, the processor will receive instructions and data from a read only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. Information carriers suitable for embodying computer program instructions and data include all forms of non volatile memory, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
To provide for interaction with a user, aspects of the described techniques can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input.
The techniques can be implemented in a computing system that includes a back-end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front-end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation, or any combination of such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), e.g., the Internet.
The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other.
A number of embodiments have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the inventions. For example, although particular graphical representations were shown as exemplary in the figures, other representations that are helpful to a user may also be employed. Accordingly, other embodiments are within the scope of the following claims.
This application claims the benefit of U.S. Provisional Patent Application No. 60/734,675, filed Nov. 7, 2005, and entitled “Local Search and Mapping for Mobile Devices”, the contents of which are hereby incorporated by reference.
