With reference to FIG. 1, a simple schematic diagram of a system 100 for retrieving geographical directions on a GPS-equipped mobile device is shown. FIG. 1 may be used to describe other methods of retrieving and sending directions and locations to and from GPS enabled mobile devices later in this application. A mobile device 102 may be any GPS-equipped device capable of sending and receiving GPS information such as a mobile telephone, personal digital assistant (PDA), personal GPS device, automobile mounted GPS device, BLACKBERRY® device, APPLE iPHONE®, mobile phone running ANDROID®, etc. The mobile device 102 may send and receive signals 116 from one or multiple GPS satellites 104, resulting in the satellites 104 being able to triangulate, pinpoint, approximate, or interpolate the location or approximate location of the mobile device 102. The mobile device 102 may also be capable of transmitting and receiving a standard mobile telephone signal 118, or short service message (SMS) or other text carrying signal which can then be sent from an antenna 106 or a satellite to an operator 108 or computer controlled automatic operator 110 via landline 114 or other communication technique 112. Other communication techniques include electronic communications across broadband devices, mobile telephone communications, satellite communications, etc. A landline indicates a terrestrial telephone network, which can be analog or preferably digital.
These channels of communication allow a user of the mobile device 102 to request directions to a location, which the operator 108 or computer controlled automatic operator 110 can decipher, e.g., via voice recognition, touch pad tone recognition, text recognition, etc., and return coordinates for the location to the mobile device 102, for purposes of the mobile device 102 displaying a present location of the mobile device 102 and/or a location of the desired destination and/or directions to proceed to the destination, possibly in the form of a map 120, text message, graphical layout, etc.
The user of the mobile device 102 may request directions via any available communications channel, such as via a telephone call to an operator 108 or computer controlled automatic operator 110, a text message to an operator 108 or computer controlled automatic operator 110, a telephone call into an automated response system (e.g., such that the user can enter keystrokes that signal desired responses to the automated response system), etc.
FIGS. 2-6 show various methods according to multiple embodiments. Each method may be carried out in the context of functionality of FIG. 1, or in any other environment as desired.
Referring to FIG. 2, in operation 202, a request for a geographical destination is received from a mobile device. In operation 204, geographical coordinates of the destination are determined. In operation 206, the coordinates are transmitted to the mobile device.
Referring to FIG. 3, in operation 302, a verbal request for a geographical destination is received from a mobile device. In operation 304, geographical coordinates of the destination are determined. In operation 306, the coordinates are transmitted to the mobile device.
Referring to FIG. 4, in operation 402, a request for a geographical destination is transmitted from a mobile device to a remote location. In operation 404, geographical coordinates of the destination are received. In operation 406, a map showing at least one of a present location of the mobile device and the destination is output.
Referring to FIG. 5, in operation 502, a verbal request for a geographical destination from a mobile device is transmitted to a remote location. In operation 504, geographical coordinates of the destination are received. In operation 506, a map showing at least one of a present location of the mobile device and the destination is output.
Referring to FIG. 6, in operation 602, a present geographical location of a remote mobile device is received at a local mobile device. In operation 604, a map showing a present location of at least one of the local mobile device and the received location of the remote mobile device is output.
In each embodiment, variations are possible at each step. For instance, the request for a geographical location may be initiated by the user of the mobile device, or may be automatically transmitted when certain predefined criteria are met. Furthermore, the request may be a verbal request. The request may be received by a live person or by an automatic device capable of responding to the request with the geographical location desired. The person receiving the request may be at a call center designed to handle such requests, or any other location.
In other embodiments, the geographical coordinates of several potential destinations may be determined and sent to the mobile device. The user can then select which destination to display on the mobile device and/or receive directions to. Further, one of the locations sent to or by the mobile device may be the present location of the mobile device, which can then be displayed on the mobile device as a point on a map, and/or can be used to generate directions from the present location to a desired location. The present location of the mobile device may be determined through GPS, triangulation of the mobile device, proximity to the closest mobile telephone tower, etc.
The file or transmission format or medium of the geographical coordinates, location, etc. may be transmitted to a mobile device using any known method. For example, the coordinates may be send in any format or messaging type that can be recognized by the mobile device as would be known to one of reasonable skill in the relevant art, such as SMS, a markup language such as hyper text markup language (HTML), plain text, rich text, email message, etc. Moreover, where a first mobile device sends its present geographical location information to a remote mobile device, the first mobile device may send the geographical location in the form of an email, a text message, SMS, message, a map with a marker showing the present geographical location generated at the sending device, etc. The receiving mobile device may then output an indication of received geographical location information, the map or a map generated based on the information, etc. Note that the receiving device may download map data and/or other data from a remote server as part of the outputting process. Moreover, any of the foregoing can be used to transmit location information to a receiving device or system, or to transmit location information from a sending device or system.
In another embodiment, the map that may be displayed on the mobile device may have a geographical representation highlighting at least part of a route between the present location and the destination. The map and/or route can include, among other things, roadway names, place names, points of interest, arrows, instructions to turn left or right, distances, etc. Moreover, the output can be updated from time to time based on an updated present location of the mobile device. In addition, text may accompany the map or may be provided alone which describes the present location of the mobile device and/or directions to reach the destination.
In a further embodiment, the mobile device may output verbal commands that contain at least a portion of the directions determined between the present location and the desired destination. This can include, among other things, roadway names, instructions to turn left or right, distances, etc. In addition, the verbal commands may include turn-by-turn directions, which aid a traveler in arriving at a destination or waypoint. Also, the associated visual commands may correspond to the verbal commands, and the visual display, such as a map, may update based on the progress and position of the mobile device. The mobile device may also output at least a portion of the directions in text format.
In still other embodiments, the method may be performed by another mobile device, thus allowing one user's device to send its location back to the requesting device. The user's device may receive the request, and may output the request to the user, e.g., as audible signals.
In some embodiments, the geographical coordinates of one or more potential destinations may be sent to the mobile device from the potential destination. For example, a restaurant may send the coordinates of the restaurant to a mobile phone in response to being called from the phone and asked directions to arrive at the restaurant. In this example, the restaurant may send the coordinates of the restaurant, and the mobile phone may use these coordinates along with a present location of the mobile device as determined through GPS or some other technique, to determine a route between the present location and the restaurant. Coordinates may be longitude and latitude, a street address, or some other code which can be understood by the mobile device such that the location of the restaurant can be pinpointed by the mobile device in proximity to the present location (such as 5 miles north, 3 miles east, two blocks south, etc.).
In more embodiments, the geographical coordinates of one or more potential destinations may be sent to the mobile device from a webpage, website, Internet server, etc. For example, the location of a potential destination may be requested by the mobile device and the website may respond by sending the coordinates of the potential destination. The mobile device may use these coordinates along with a present location of the mobile device as determined through GPS or some other technique, to determine a route between the present location and the potential destination. For example, a user may request the location of the closest pizza restaurants (or any other type of business, residence, person, government agency (such as police station, fire department, etc.), point of interest (e.g., park, stadium, etc.), etc.) on a webpage which can then display a list of potential matches. The user may then select one or more of the returned matches, and the webpage may send the coordinates of one or more of the selected matches to a mobile device where the user may access the locations.
In further approaches, the route calculated can be based on or include some criteria, such as a fastest route, shortest distance, shortest time, whether traveling by automobile or foot, modes of transit such as mass transit including transit stops, fees associated with chosen routes, traffic conditions on chosen routes, restrictions on chosen routes (such as weight limitations; height limitations, walking path availability, time restrictions, etc.), etc.
In one example of use, a user dials 411 from his or her mobile telephone, upon which the mobile telephone transmits the tones, pulses, bits, etc., associated with dialing 411. A connection is made between the telephone and an automated system and/or a call center. The automated system and/or a person at the call center may ask for the query, which is transmitted to the user's telephone. In response, the telephone transmits the user's request for a location of a pizza restaurant near the user's location and/or some other location. In the former case, a location of the mobile telephone may be transmitted from the mobile telephone itself, estimated based on which tower the telephone is communicating through, etc. In the latter case, the user may state a location such as a city, relative to some street address or cross street, etc.
If the name of the pizza restaurant is given, the location of that particular restaurant can be returned. If there are several branches of the restaurant in the vicinity of the mobile telephone, then the locations of the branches can be transmitted to the mobile telephone for output to the user. The user selection can be received and a route to the selected branch can be output. The route may be output as a map, a list of directions, a single direction which after being executed results in the next direction being displayed, a combination of any of the former, etc.
Similarly, if the request is simply for a pizza restaurant (or any other type or class of business, a person or persons, etc.), then the names and/or locations of several pizza restaurants can be sent to the mobile telephone for output to the user for selection of one or more thereof. These names and/or locations may be sent to the mobile telephone by the pizza restaurant (or any other type or class of business, a person or persons, etc.), using a telephone, computer, etc., that is capable of sending the coordinates such that the coordinates can be recognized by the mobile telephone.
A request for a location of a person's home (or business, or present location) can also be made. For instance, assume the user requests directions to Dominic Kotab's home. Coordinates (e.g., a street address, longitude and latitude, etc.) of Dominic Kotab's home may be obtained or derived from a database or other data source, e.g., white pages. The mobile device may be able to generate a route to the received street address based on data stored on the device, or it may retrieve any additional data it may need to calculate the route. Of course, any information that is stored on the mobile device may be used in any of the embodiments in order to expedite the process, or to save on charges that may be incurred for data transmission, time on telephone, etc.
In another approach, a request may include a telephone number, which may be used to determine a location associated with the telephone number. The resultant location can be handled as described herein. For example, a telephone number for a friend's mobile telephone may result in the location of the friend's mobile telephone being returned to the mobile device, and a route between the present location of the mobile device and the friend's mobile telephone can be determined.
Filters can also be applied. For example, the user may indicate a preferred distance of the destination from his or her location and/or some other location, e.g., in a city, relative to some street address or cross street, etc. According to one example, if a user is driving from point A to point B, and desires to stop at a CHEVRON gas station along the way (possibly because the user prefers gasoline with the TECHRON additive), the filter may remove CHEVRON gas stations from the returned locations that do not fall within a predetermined proximity to the path of travel between point A and point B. In another approach, restaurants within some predefined radius of the mobile device, or of some other location, can be output.
Methods for determining a present location of a mobile device may include, but are not limited to, GPS (preferably built into the device), other types of satellite positioning, estimation based on ground communications (e.g., triangulation to towers, signal strength proximity, etc.), etc. Moreover, combinations of any methods disclosed herein may be used.
Data for the maps output by the mobile device may be stored locally, downloaded in portions or as a whole as needed, a combination of these, etc. Moreover, the map may be rendered either via the mobile device or may be generated remotely and sent to the mobile device for output. In addition, the map may be rendered as lines and blocks, as satellite imagery, as a combination of shapes, symbols, and satellite imagery, etc.
To conserve power, the mobile device may selectively (e.g., automatically, under control of a user, etc.) suspend and initiate determination of its present location. For instance, GPS (or other) navigation of a mobile device may be disabled until the destination information is received, upon which it is initiated at least long enough to discern the present location. The GPS navigation may remain on until the destination is reached, or it may periodically request a position until the destination is reached, possibly determining the rate at which to periodically determine the position based in part on the rate of travel.
While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of an embodiment should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
