Description

200930981 IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to an improved navigation apparatus and method. [Prior Art] A portable navigation device (PND) including a GPS (Global Positioning System) signal receiving and processing unit is well known and widely used as an in-vehicle navigation system. Essentially, modern PNDs include: • A processor,

❿ - memory (at least one of volatile memory and non-volatile memory, and usually both), - map data stored in the memory, a software operating system and (as appropriate) Executing one or more additional programs for controlling the functionality of the device and providing various features, a GPS antenna by which satellite broadcast signals including location data can be received and processed at any time to determine the current state of the device Position, (as appropriate) an electronic gyroscope (gyr〇sc〇pe) that generates signals and accelerometers that can be processed to compare current angular acceleration and linear acceleration, and further, combined with locations derived from GPS signals Information, determining the speed and relative displacement of the device and the vehicle in which the device is mounted, input and output components, examples including a visual display device (which may be a touch-sensitive display to allow user input), more than one Physical button to control on/off operation or other features of the device, a speaker for voice output, 127911.doc 200930981 (as appropriate) one or more physical connections And the physical connector or the physical connector transmits one or more data signals to the device and receives power and optionally one or more data signals from the device, and - (as appropriate) Or multiple wireless transmitters/receivers to allow communication over mobile devices and other signal and data networks (eg, Wi_Fi, WiMax, GSM, etc.). ❹

The utility of the utility is mainly manifested in its ability to drum the route between the starting position or the current position and the destination, and the destination can be input by a user of the computing device by a wide variety of different methods (eg, #by zip code, Street name and number), and can be reduced to the known, favorite or recently arrived destinations. Typically, the PND is used to calculate the "best" or "best" route software between the originating address location and the destination address location based on the map data. The "best" or "best" route is based on predetermined criteria and is not the fastest or shortest route. The choice of route to guide the driver can be very complex and the selected materials can take into account existing and projected traffic and road conditions, historical information about road speed and the driver's own preferences for determining road alternatives. In addition, the unit continuously monitors road and traffic conditions and provides or elects to change routes due to changing conditions on which the remaining trips will take place. Instant traffic monitoring (10) based on various technologies (eg, mobile phone calls, fixed cameras, (10) fleet tracking) is being used to identify traffic delays and (4) the mid-range navigation device can usually be mounted on the vehicle dashboard, but can also be formed as 127911 .doc 200930981 Part of the onboard computer or car radio. Navigation device = part of the system, such as PDA (personal navigation device), media = two: inciting the phone or the like - and in this case, by executing the route calculation and along the software The navigation of the route applies the general functionality of the portable system. In any case, the user interacts with the navigation device to select the desired route (as appropriate for the list of ❹ lines). Depending on the situation, the user = intervene or direct the route selection process 'for example, by specifying the line of conduct' should avoid or be subject to certain routes, roads, locations. The route calculation form of pND forms a main function provided, and the navigation of the line is another main function. During the course of the journey along the calculated route, the PND provides visual and/or voice commands for directing the user along the selected route to the end of the route, which is the desired destination. The PND usually displays the map information on the screen during navigation. (4) The information is periodically updated on the screen, so that the displayed map information indicates the current location of the device and thus indicates the current location of the user or the user's vehicle. Navigate in the car). The icon displayed on the screen usually indicates the location of the previous device and is centered and also displays information about the current and surrounding roads and other map features. In addition, depending on the situation, the navigation information may be displayed in the status bar above, below or on the side of the displayed map information. Examples of the navigation information include the distance from the current road that the user needs to select to the next deviation, and the deviation from Nature, this property can be represented by a further graphical representation of the particular type of deviation (eg, left turn f or right turn). The navigation function also determines the content, duration, and timing of the voice commands, which can be directed to the user by the instructions 127911.doc 200930981 ==. If you can understand, such as „1〇.,, the installation is large* processing and analysis. As mentioned before, the user and the installation are remotely controlled by the touch screen, or by other means or by other means: The remote control, activated by sound or by any other suitable means. The route weight = the more important function provided is 'automatic route in the following cases: during the navigation along the previously calculated route, the user deviates from the appropriate That is, the ^C pass condition indicates that the alternate route will be more advantageous, and the device can automatically recognize these conditions automatically, or - the right user actively causes the device to perform route recalculation for any reason. Also known as 'allowed by The user-defined criteria are used to calculate the route. For example, the user may prefer the scenic route calculated by the device. The software will then calculate various routes and prefer to include the highest number of points of interest along its route (known as po1) Routes, such points of interest are marked as (for example) beautiful scenery. Other route calculations and navigation standards based on (10) are also possible. Although route calculation and navigation functions are important for the overall utility of pND However, it is possible to use the device purely for information display or "free driving", where only the map information related to the location of the device is displayed, and the route has not been calculated and the device is currently not performing navigation. This mode of operation is often Applicable when the user knows the route to travel along and does not need navigation assistance. _When the map information displayed during navigation or in the self-driving mode of operation of the device is limited by the newspaper, and usually Only limited to basic roads 127911.doc 200930981 boundaries, bridges, and basic indications of points of interest (P0I), traffic jams, text-based street names, and land uses (eg, multi-apartment areas and no-building vacant lots) Other basic illustrations and color graphic representations. In the case of Xu Xi, the digital map information available from the provider only includes this basic Beixun, but more recently, some cities or cities in these countries have enhanced Type map information has become available. 'In this enhanced map information' includes a wide variety of additional digital information, examples including building construction, housing Digital photo of the front of the house, indicating the use of land, street lights, electric trusses, tram tracks, train tracks, zebra crossings and traffic signs, road surface types, road markings, traffic lights, landmarks within distance, distance within Cities, vivid patterns (eg, water waves), bicycle lanes, bus lanes, additional (eg, commercial, agricultural, tourism) information about P〇I or locations (eg, HTML or other forms of rich content), enhanced POI icon, traffic information, detailed shadows, weather information. If you know that 'map information providers are constantly improving map information, ~ 〇# fast travel, preferably only show limited _ information is justified First, if you are based on the process of becoming available and the additional information listed above, and taking into account the limited processing power, memory and display capabilities of modern touches, • understand that when so much additional information is included in the map data ( When it is in the city map data, it is difficult to achieve a seamless transition between the displayed map information. • Map data cannot be processed at all to display quickly enough. Secondly, the display of so much information on the display screen of the device is likely to distract the user's attention while driving, and thus the display of basic information is preferred. Finally, 'whether or not the enhanced map information is displayed on the device, the 127911.doc 200930981 user can travel at any high speed, and the user has little time to view the local environment anyway', so the benefits of this enhanced information are displayed. unimportant. The headed PND includes one or more options to allow the user to select which particular features within the enhanced map information are available for display. However, changes in the options on the pND during exercise (specifically, at any speed) can also be dangerous and inevitably highly distracting the user. However, for a user of the device, particularly when traveling relatively slowly through any location unfamiliar to the user, it would be advantageous to present an enhanced amount of utility for the orientation of the auxiliary user in the location. Map information. It is an object of the present invention to provide a method and PND that is adapted to display enhanced map information in a useful manner and thus overcomes the described disadvantages. SUMMARY OF THE INVENTION According to the present invention, there is provided a method of displaying enhanced map information on a PND, comprising the steps of: determining a speed of the PND, and displaying map information on a display screen of the PND, the map information Continuously and/or periodically renewed to account for the displacement of the device caused by its velocity, characterized in that the degree to which the displayed map information is enhanced to include one or more enhanced features depends to some extent on the The speed of the PND, these enhanced features are 127911.doc •12· 200930981 selected from the group consisting of: building structure, discrete facades of houses, landscapes, grounds and houses, digital photos of distant views, representing land Patterns of use, street lights, cable towers, tram tracks, train tracks, zebra crossings and traffic signs, road surface types or patterns indicating the type of road surface, road markings, traffic lights, landmarks within distance or their digitized photos, within distance City or its digital photos, vivid patterns,

In a further aspect of the invention, a computer program is provided for carrying out the above method, and a pnd and/or navigation system for performing the described method by phase modulation is also provided. [Embodiment] FIG. 1 illustrates an example view of a Global Positioning System (Gps) that can be used by a navigation device. These systems are known and used for a variety of purposes. In general, GPS is a satellite radio based navigation system that is capable of determining continuous position, speed, time, and (in some cases) direction information for an unlimited number of users. The GPS previously known as NAVSTAR incorporates a plurality of satellites that operate with the Earth in extremely precise orbits. Based on these precise orbits, GPS satellites can pass their positional splits to any number of receiving units. The GPS system is implemented when a device specially equipped to receive GPS data begins scanning for radio frequencies for GPS satellite signals. After receiving a radio signal from a GPS satellite, the device determines the exact location of the satellite via one of a plurality of different conventional methods. In most cases, the device will continue to scan the signal for 127911.doc 14 200930981 until it has obtained at least three different satellite signal flavors, often using other triangulation techniques with only two signals. Determine the location). After performing a geometric triangulation, the receiver uses three known locations to determine its own two-dimensional position relative to the satellite. This determination can be made in a known manner, and obtaining a fourth satellite signal will allow the receiving device to calculate its three-dimensional position in a known manner by the same geometric calculation. Location and speed data can be continuously updated in real time by an unlimited number of users. As shown in Figure 1, the GPS system is generally indicated by the reference numeral ι〇〇. A plurality of satellites 120 are in orbit around the earth 124. Each _ satellite ι2〇 track may not be synchronized with other satellites, and it is likely to be different. GPS receiver 140 is shown to receive spread spectrum Gps satellite signals from various satellites 12A. The spread spectrum satellite signal 16 continuously transmitted from each satellite 120 utilizes a highly accurate frequency standard achieved by an extremely accurate atomic clock. Each satellite 120 transmits a data stream indicative of its particular satellite 120 as part of its data signal transmission 160. Those skilled in the relevant art will appreciate that the GPS receiver device 140 typically obtains a spread spectrum GPS satellite signal 160 from at least three satellites 120 for the GPS receiver device 140 to calculate its two dimensional position by triangulation. The acquisition of an additional signal, which causes a signal 160 from a total of four satellites 120, permits the GPS receiver device 140 to calculate its three dimensional position in a known manner.
