Navigation device with control feature limiting access to non-navigation application

[0001] The present invention is generally related to a navigational device configured to implement non-navigation applications, and more particularly to a device that enables and disables non-navigation applications based on access codes.

[0002] Portable handheld electronic devices exist today for a variety of uses and applications. For example, one type of conventional electronic device is a dedicated multi-language dictionary or translator, such as for use during travel to countries in which the operator is not necessarily fluent in the local language and customs.

[0003] Another type of conventional electronic device is a portable navigation device, such as for use with that the global positioning system (GPS). Portable navigation devices offer a variety of features related to routing and navigating through roadway networks, locating points of interest and the like.

[0004] However, heretofore, travelers were required to carry one portable device language translation and dictionary functions and a separate portable device that offered navigation and routing functions. A need exists for a single portable device capable of offering the functionality of a navigation device and of a language translator/dictionary, where the separate functions and applications are fully integrated with one another.

[0005] In one embodiment, a portable navigation device is provided that includes a receiver configured to receive signals from GPS satellites. The device includes memory that stores a non-navigation application and non-navigation information related to the non-navigation application. A user interface is configured to enable an operator to enter non-navigation instructions related to the non-navigation application. The a processor module is provided that calculates a position of the device based on the signals from the GPS satellites. The processor module implements the non-navigation application and performs non-navigation operations defined by the non-navigation application based on the non-navigation instructions entered by the user. The processor module disables the non-navigation application after a predetermined trial period of time following a start time unless and until an application access code is entered. Optionally, a cartridge they may be included that is configured to receive an application access cartridge containing the application access code. The code indicates that access to the non-navigation application has been purchased by the user of the device. The processor module enables the non-navigation application when the application access cartridge is entered into the cartridge bay with a valid code. The processor may not disable the non-navigation application, such as when an application access code is incurred before and in of the predetermined trial period of time. The processor module validates the application access code and disables the code on the cartridge once utilized in order to prevent the cartridge from being used again.

[0026] In the following detailed description of the invention, reference is made to the accompanying drawings which form a part hereof, and in which is shown, by way of illustration, specific embodiments in which the invention may be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized and changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.

[0027] The embodiment discussed hereafter are is drawn to navigational systems and devices having navigation and, route calculation capabilities. One type of navigational system includes Global Positioning Systems (GPS). Such systems are known and have a variety of uses. In general, GPS is a satellite-based radio navigation system capable of determining continuous position, velocity, time, and in some instances direction information for an unlimited number of users. Formally known as NAVSTAR, the GPS incorporates a plurality of satellites which orbit the earth in extremely precise orbits. Based on these precise orbits, GPS satellites can relay their location to any number of receiving units.

[0028] The GPS system is implemented when a device specially equipped to receive GPS data begins scanning radio frequencies for GPS satellite signals. Upon receiving a radio signal from a GPS satellite, the device can determine the precise location of that satellite via one of different conventional methods. The device will continue scanning for signals until it has acquired at least three different satellite signals. Implementing geometric triangulation, the receiver utilizes the three known positions to determine its own two-dimensional position relative to the satellites. Additionally, acquiring a fourth satellite signal will allow the receiving device to calculate its three-dimensional position by the same geometrical calculation. The positioning and velocity data can be updated in real time on a continuous basis by an unlimited number of users.

[0035] FIG. 4 illustrates a block diagram of one embodiment for the electronic components 400 within the device 100, 230 or 310. The electronic components 400 shown in FIG. 4 include a processor 436 which is connected to a GPS antenna 414 through GPS receiver 438 via line 441. The GPS antenna 414 is configured to receive GPS signals from satellites. The processor 436 interacts with an operating system (such as PalmOS; Pocket PC) that runs selected software depending on the intended use of the device 100, 230 or 310. Processor 436 is coupled with memory 442 such as RAM via line 444, and power source 446 for powering the electronic components of the device 100, 230 or 310. The processor 436 communicates with touch sensitive display screen 426 via data line 448.

[0036] The electronic components 400 further include two other input sources that are connected to the processor 436. Control buttons 428 are connected to processor 436 via line 451. A map data cartridge 433 and/or a security card 431 may be inserted into cartridge bay 432 that is connected via line 452 to the processor 436. A conventional serial I/O port 454 is connected to the processor 436 via line 456. Cellular antenna 416 is connected to cellular transceiver 458, which is connected to the processor 436 via line 466. Processor 436 is connected to the speaker/headphone jack 434 via line 462. Line 462 is also connected to a speaker 435 for audibly playing navigation and language translation/dictionary information. For example, the speaker 435 may output turn-by-turn directions, words or phrases in a selected language and the like. The device may also include an infrared port (not shown) coupled to the processor 436 that may be used to transmit information from one device to another.

[0037] The electronic components 400 also include memory 464 that may be configured to store one or both of a map database 466 and a language database 468. The map database 466 stores cartographic mapping information associated with a roadway network, while the language database 468 stores dictionary information, language information, translation information and the like. In operation, the processor 436 accesses the map database 466 and/or map data cartridge 433 in connection with navigation operations and routing calculations. The processor 436 accesses the language database 468 in connection with translation and other language related operations.

[0038] Optionally, the language database 468 and the map database 466 may be provided in entirely separate memory modules. For example, memory 442 may store the map database 466, while memory 464 stores the language database 468. For example, one or both of the language database 468 and map database 466 may be provided on plug-in memory modules that are plugged into the cartridge bay 432 and subsequently accessed by the processor 436 to perform language/translation operations and navigation operations, respectively.

[0039] The electronic components 400 shown in FIG. 4 are powered by a power source (not shown). Different configurations of the components shown in FIG. 4 are considered within the scope of the present invention. For example, in one embodiment, the components 400 shown in FIG. 4 are in communication with one another via wireless connections and the like. Thus, the scope of the navigation device includes a portable electronic navigational aid device.

[0040] The cartographic database includes any number of locations and data indicative of thoroughfares of a plurality of types connecting certain ones of the locations. In memory, different types of thoroughfares are contained in a data structure organized in a hierarchy of detail levels, or layers. The processor 436 utilizes the route calculation algorithm to find a path, or convergence, between any two of the number of locations based on various criteria. Optionally, a set of criteria includes; a number of jump segments requirement, a distance requirement, a minimum memory usage requirement, a maximum memory usage requirement, and an at least one jump segment requirement. The set of criteria may be independently variable in order to tailor an aggressiveness with which the route calculation algorithm forces switching between different levels in the hierarchy of detail levels. Optionally, the hierarchy of detail levels may include a hierarchy of ever-decreasing detail levels such that a lowest level includes the greatest amount of detail. Any other suitable hierarchy of detail levels may be used.

[0041] In one embodiment, a type of thoroughfare in any given layer of the hierarchy of detail layers is determined by a traversability of the thoroughfare. For example, the traversability of the thoroughfare can be determined by the driveability of a road. Herein, the driveability of the road may be determined by the classification of the road, a speed classification of the road, a driving history on the road, and the like. However, the invention is not so limited and one of ordinary skill in the art will understand upon reading and comprehending this disclosure, that other criteria for determining the presence of a type of thoroughfare in any given layer of the hierarchy can be suited to the present invention.

[0042] Electronic components 400 further include a display 440 in communication with the processor 410 and the memory 430. The display 440 is adapted to display all or part of the navigation information and the language/translation information.

[0043] Next, an exemplary operation flow will be explained in connection with a series of exemplary screens presented on the display 426 and shown in FIGS. 5-14. FIG. 5 illustrates a main menu 500 presented when the device is initially turned on or returned to the home page/menu. The main menu 500 includes a series of virtual buttons or icons or soft keys associated with certain functions (generally “icons”). Each icon represents a defined area on the screen 502, with each area having a sufficient size and separation from one another to be independently selected with a finger touch (e.g. a 6 mm×6 mm square area, a 10 mm×10 mm square and the like). The icons maybe any shape (e.g. square, rectangle or, circular, triangular, trapezoidal and the like). The icons may be presented in a cascaded window manner such that certain icons overlap one another similar to the operation of independent windows on a computer.

[0044] In the example of FIG. 5, the main menu 500 includes a battery icon 504, a time icon 506, a settings icon 508, a volume icon 510, and a light icon 512. The battery icon 504 is selected when the user wishes to determine the remaining battery life, while the settings icon 508 is selected when the user desires to change the system settings of the device. Examples of system settings include map, display, and the like.

A back icon 528 directs the device to move back to a prior screen or the main menu 500. A near icon 530 instructs the device to show the user points of interest within each category nearest the user. Scroll down and scroll up icons 532 and 534 allow the user to view additional categories that, due to space limitations, are not all able to be presented on a single screen. For example, additional categories may include intersections, attractions, shopping, banks/ATM's, entertainment, recreation, community services, and the like.

[0046] The user selects one of the food icon 536, fuel icon 538 and lodging icon 540 depending on whether the user wishes to view near restaurants, gas stations, and hotels, respectively. The “spell name” icon 542 instructs the device to present an ABC formatted keypad, from which the user types a name or address of a particular location or point of interest.

[0047] The following more detailed example is set forth in connection with identifying a restaurant. However, the following description is applicable to any location or point of interest selectable through any category or subcategory. When the food icon 536 is selected, flow passes along dashed line 544 and the screen presents an alphabetical list of food subcategories 546, from which the user may select. Examples include All-Food icon 548, American food icon 550, Asian food icon 552, Chinese food icon 554, French food icon 556 and the like. A back icon 528 permits the user to move back to the category menu 522, while scroll down and scroll up icons 532 and 534 permit the user to view additional food subcategories. When the Chinese food icon 554 is selected flow passes along dashed line 560 and the screen presents a list of Chinese restaurant names 562, along with the distance 564 and direction 566 to each of the corresponding restaurants. Optionally, the restaurant names 562 may be sorted based upon the nearest restaurant to the present location of the user, alphabetically, and the like. When a particular restaurant is identified, flow passes along dashed line 568 and the screen presents information related to a selected restaurant, such as the name, address, phone number and the like. A GO icon 570 is also presented that may be selected when the user desires to calculate a route from the user's present location to the restaurant. A save icon 572 may be selected when the user desires to save the location of the restaurant as a waypoint in a waypoint list saved in the map database 466. A show map icon 574 may be selected when the user desires to view a roadway map of the area including or surrounding the restaurant selected.

[0048] FIG. 6 illustrates a screen shot 602 that is presented when the show map icon 574 is selected in FIG. 5. The screen shot 602 includes a roadway map 604 of the road network surrounding a selected restaurant 606. The screen shot 602 includes a direction indicator 608 indicating which direction is north. The screen shot 602 also includes zoom in and zoom out icons 610 and 612 that permit the user to zoom into a lower level more detailed road map surrounding the restaurant 606 or to zoom out to a higher level less detailed road map. Optionally, the user may touch an area on the roadway map 604 to “grab” a point and drag the user's finger across the screen 602 in order to scroll the map up, down, left and right. The device also offers simulated travel to the point of interest from the user's present location. Again, it is reiterated that the above example was provided in connection with identifying a restaurant. However, it is understood that the above process and screen formats may be presented with any point of interest for all categories and subcategories.

[0059] FIG. 14 illustrates a dictionary conversion page showing a German Word and two alternative interpretations in English depending upon the usage of the term. The dictionary conversion page may be presented at several points in the toolkit flow, depending upon earlier selections by the user.

[0060] FIG. 15 illustrates a flow chart of an operation sequence performed in accordance with an alternative embodiment of the present invention for providing limited access to select features or functions preprogrammed into the device. The device is configured to initially store a full and complete Tool Kit database. When the device is initially purchased by user, the full and complete tool kit database is made fully available to the user for a limited free trial term. At the end of the limited free trial term (e.g. 30 days), the device automatically disables or “times out” all or a portion of the tool kit database. Upon disablement, the tool kit features and functions are no longer accessible to the user, unless and until the user purchases a security card 431 that, when plugged into the device, re-enables all or a portion of the tool kit information, features and functions.

[0061] The security card 431 includes memory storing a code (e.g. encrypted code) that is read by the device once the security card is plugged into the cartridge bay 432 (FIG. 4). Once the security card 431 is plugged into the cartridge bay 432, the processor 436 reads the code and, based thereon, determines whether and to what extent to unlock the tool kit features and functions.

[0062] FIG. 15 illustrates in exemplary application of the free trial and security card features. At 1500, the device is initially loaded with the travel kit information, including but not limited to the dictionary and translation information. At 1502, the device configures itself to provide complete or limited access to the travel kit information for a trial term. At 1504, upon the completion of the free trial term, the device disables all or select portions of the travel kit features. The disablement occurs unless a security code has been previously loaded into the device through insertion of a security card 431. If, at the end of the free trial term, no security card 431 has been loaded, then the travel kit features are no longer provided to the user.

[0063] Should the user subsequently decided to purchase permanent access to the travel kit features, the user does so by purchasing a security card 431 that includes in memory, a valid code indicating that the user now has purchased unlimited access to the travel kit features. Once the security card 431 is loaded, the device reads from the memory thereon the code and, at 1508, determines whether the code is valid. For example, all devices may be preconfigured with a common general validation code that is compared to the code on the security card 431. Alternatively, separate codes may be provided to individual devices or devices sold within selected geographic regions or select periods of time (e.g. annually or based on the version of the device). At 1510, once the security code is validated, the device re-enables all or a portion of the travel kit features.

[0064] For example, the user may desire to only have certain travel kit features and thus purchase a lower cost subset of the travel kit features (uniquely identified by a particular security code). Thus, different security codes may indicate to the device that the user is entitled to different levels of access to the features and functionality of the travel kit information. At 1512, the device disables the security code on the security card 431 in order that the same security card 431 may not be subsequently used with the same or different device. The disablement may be achieved by erasing the security code on the security card 431, by writing over the security code, or by writing additional information to memory within the security card 431 indicating that the card has been used.

[0065] While the description in connection with FIG. 15 relates to a toolkit application, it is understood that the process of FIG. 15 and the security card 431 (FIG. 4) may be utilized in connection with navigation applications and other non-navigation applications. The travel toolkit is only one example of non-navigation applications. More generally, the process of FIG. 15 may be carried out with a portable navigation device that includes a receiver configured to receive signals from GPS satellites. The device includes memory that stores a non-navigation application and non-navigation information related to the non-navigation application. A user interface is configured to enable an operator to enter non-navigation instructions related to the non-navigation application. The a processor module is provided that calculates a position of the device based on the signals from the GPS satellites. The processor module implements the non-navigation application and performs non-navigation operations defined by the non-navigation application based on the non-navigation instructions entered by the user. The processor module disables the non-navigation application after a predetermined trial period of time following a start time unless and until an application access code is entered. Optionally, a cartridge they may be included that is configured to receive an application access cartridge containing the application access code. The code indicates that access to the non-navigation application has been purchased by the user of the device. The processor module enables the non-navigation application when the application access cartridge is entered into the cartridge bay with a valid code. The processor may not disable the non-navigation application, such as when an application access code is incurred before and in of the predetermined trial period of time.

[0066] The cartridge bay 432 is configured to receive the application access cartridge (security card 431) containing the application access code. The code on security card 431 indicates that access to the non-navigation application has been purchased by the user of the device. The processor 436 enables the non-navigation application when the application access cartridge is entered into the cartridge bay with a valid application access code. The processor 436 re-enables the non-navigation application only when the non-navigation application has already been disabled (such as at the end of the predetermined trial period of time). Alternatively, the processor 436 may never disable the non-navigation application, such as when an application access code is entered before an end of the predetermined trial period of time.

[0067] The processor 436 may perform an initialization operation upon the device when the device is turned on for the first time after the user has purchased the device. In one example, the processor 436 may set the predetermined trial period of time to represent a set number of days (e.g. 30 days following purchase, until December 31 of the present calendar year, and the like) following initialization, or first start up, of the device. Alternatively, the predetermined trial period of time may be defined based on the number of hours that the device is used. For example, a new device may include 10, 20, or 50 free hours of use of the toolkit. Alternatively, the processor 436 may not perform an initialization operation, but instead simply initiate the predetermined trial period of time when the device is first started-up after purchase. As a further alternative, the predetermined trial period of time may begin after the user logs all into the manufacturer's web site and registers the device with the manufacturer.

[0068] Optionally, the application access code may be entered through the I/O port for 54, an infrared input, a user keypad, control buttons for 28, the display/input for 26, and the like. For example, a user may purchase a security code and enter the security code through the keypad or control buttons for 28.

[0069] While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
