Description

201015052 IX. Description of the Invention: [Technical Field] The present invention relates to a navigation device configured to provide instructions (especially instructions for navigation of a route) to a user. [Prior Art] Portable computing devices, such as portable navigation devices (PNDs) including Global Positioning System (Gps) signals* receiving and processing functionality, are well known and widely used as in-vehicle or other vehicle navigation systems. . 10 In general, modern PNDs include a processor, memory (at least one of volatile memory and non-volatile memory, and usually both) and map data stored in the memory. The processor cooperates with the memory to provide an execution environment in which a software operating system can be built and, in addition, often & or an additional software program to enable the functionality of the PND to be controlled' and provide various other functions. In general, such devices further include allowing the user to interact with the device and controlling (4) the device's - or multiple input interfaces and - or multiple output interfaces, through which the information relay can be relayed To the user. Illustrative examples of output interfaces include a visual display and a speaker k _ for audio output. Illustrative examples of the input interface include control of the on/off of the device or other features - or multiple entities (4) if the device is built into the carrier, the buttons are not necessarily in the device On its own, it can be on the steering wheel and a microphone for detecting user utterances. In a particular configuration, the output interface display can be configured as a touch-sensitive display (via touch-sensitive overlay or other) to provide an input interface, by means of the 135346.doc 201015052 input interface, by means of the user Touch to operate the device. Devices of this type will also include one or more physical connector interfaces through which power signals and conditional data signals can be transmitted to and received from the device. Situation information letter, number and, as appropriate, one or more wireless transmitters/receivers, which allow for v-cell and other signal and data networks (eg, Bluetooth (BlUet〇〇th) Wi-Fi Communication over Wi-Max GSM, UMTS and similar networks. ❷ , This type of PND also includes a GPS antenna through which satellite broadcast signals including location data can be received and subsequently processed to determine the current location of the device. PNDs also include electronic gyros and accelerometers that generate nicknames that can be processed to determine the current angular and linear acceleration, and in conjunction with positional information derived from GPS signals to ensure that the equipment is installed and thus installed. The speed and relative displacement of the equipment's carrying tools. Typically, these characteristics are most commonly provided in the navigation system within the vehicle, but may also be provided in the PND (if this is advantageous). - The utility of these PNDs is primarily manifested in their ability to determine the route between the first location (usually, the burst or current location) and the second location (usually the destination). Such locations may be entered by the user of the device by any of a wide variety of different methods, for example, by postal code, street name and house number, previously stored, known "purpose Land (such as famous locations, municipal locations (such as stadiums or swimming pools) or other points of interest) and favorite destinations or destinations that have recently been visited. 135346.doc 201015052 This type of PND can be mounted on the instrument panel or windshield of the carrier's but can also be formed as part of the onboard computer of the carrier radio or as part of the control system of the carrier itself. The navigation device is also part of a handheld system, such as a PDA (Portable Digital Assistant), a media player, a mobile phone or the like, and under these conditions, the conventional functionality of the handheld system is by software. It is installed on the device to perform route calculations and navigation along the calculated route.

During navigation along the calculated route, such PNDs often provide visual and/or audio commands to direct the user along the selected route to the end of the route, i.e., the desired destination. It is useful to direct the user to the end of the route (also _, the desired destination) along the route of the _ pick. PND also often displays map information on the screen during navigation, which is periodically updated on the screen so that the current location of the display is displayed and thus represents the user or user's carrier = front position (if the device is being used Navigation within the vehicle). The icon displayed on the screen usually indicates the current device location and is centered, and map information and other map features of the current and surrounding roads near the current device location are also being displayed. In addition, the status map above, below or on the side of the map information is displayed as a guide. = The example of the navigational communication includes the current road to the next from the user's need to select - the distance of the deviation, the nature of the deviation, this property may be A further graphical representation indicating a particular type of deviation (eg, a left turn or a right turn). The navigation function also determines the heart, duration, and timing of the voice commands that can be used to guide the user along the route. As you can see, simple instructions such as "1〇〇瓜后左 135346.doc 201015052 转 • need a lot of processing and analysis. As previously mentioned, the user's interaction with the device can be by touch screen, or otherwise or by a driver-mounted remote control, by voice activation or by any other method. ' . Although the route calculation and navigation functions are important for the overall utility of the pND, it is possible to use the device purely for information display or free driving, which only displays map information related to the current device location, and it has not yet calculated the way out. ❹ and the device is not currently performing navigation. This mode of operation is often applicable when the user knows the route to travel along and does not require navigation assistance. Devices of the above type (eg 920T manufactured and supplied by TomTom International BV) Type) provides a reliable way for the user to navigate from one location to another. When the user is unfamiliar with the route to the destination to which they are navigating, 'these devices have great utility. During the navigation of the route, pne> often provides visual and/or audio commands to direct the user along the selected route to the end of the route, ie the desired destination. The PND is also often used during navigation. Map information is displayed on the screen. 'This information is updated regularly on the screen so that the displayed map information indicates the current status of the device. And thus indicates the current location of the user or user's carrier (if the device is being used in the carrier ^ navigation). The display displayed on the screen usually indicates the current device location and is centered, which is also displayed in Map information and other map features of the current and surrounding roads near the current device location. In addition, depending on the situation, navigation information can be displayed in the status bar above, below or on one side of the displayed map information, 135346.doc 201015052 Navigation Information Examples include the self-deviation distance μ~ the current path from the user to the bottom-to-be-make distance, the deviation from the class m > nature of this property can be represented by a further illustration indicating the deviation of the particular ^ two turns). The navigation function also determines the timing and timing of the voices within the voice command, which can be used by the Guhai command to move along the route. B is wrong with the touch screen, the remote control 1n is activated by the steering column, or by any other suitable method. The known PND is based on static, A few custom maps to select educating shaking to provide a user of. " The PND system installed in a carrier and known to select the command depending on the speed of the carrier is currently based on the map geometry. ',, and ' use the acoustic brain phase (4) to receive the same number of instructions for the corresponding speed at the same position. For example, when the navigation is known to be "off-to-f" - a fixed distance or a set of fixed distances, the navigation and the navigation can be displayed to the user - visual communication: or Play - audio message. Therefore, when approaching a right turn, the known navigation system can provide a series of three instructions based on the distance from the hip. "Right turn after 00 meters", "Right turn after 50 meters", "Now" Turn right. " The number of instructions provided when approaching the material is fixed, and the pass t is fixed to three, but the distance at which the instructions are provided changes depending on the speed. For example, when the command is given The farthest distance varies depending on the speed at which the vehicle travels. n In some cases, the command has been found to be small or not unique for a particular situation. [Summary of the Invention] 135346.doc •10- 201015052 According to the present invention In one aspect, a navigation device is provided, comprising: a processing resource configured to select at least one instruction to be provided to a user; and a location determining device for determining one of the devices a location, wherein the processing resource is configured to select the at least one instruction depending on the location and the user environment.

Bisound, or warnings about weather or road conditions), frequency or repetition (for example, the number of times a command is spoken), the pitch of a voice used for the order, or the emphasis of a particular word (for example, Turn left at the second intersection (10)e the SEC〇ND _"), include additional wording or other information (for example, please pay special attention, you really must choose the first exit "), the volume of the command, the graphic symbol or The use of highlighting (for example, highlighting a component on a moving map displayed to the user). The environment determining module 302 is viewed from - or more of the self-measuring device 3〇4, the memory 214, and the feeder 15 The data received determines the at least one aspect of the environment in which the user is inspected. In the embodiment of Figure 6, the measuring device 3〇4 is a noise meter that measures the volume of noise within the plant. In a variation of this embodiment, the metrology equipment can be of any type and measure at least one environmental parameter experienced by the user or the vehicle, such as temperature, other weather or external conditions (such as rainfall, snowfall, Visibility, brightness level or Traffic conditions. The server 150 can provide information about environmental parameters (such as weather or other conditions, such as traffic conditions), which are provided from external sources or previously It is obtained from another navigation device that communicates with the server 15. Therefore, the measurement device 304 does not need to measure environmental data, but can be obtained from an external source. The server can also provide navigation about the navigation device 2 Information about previous experiences of other users in the location. This information may provide an indication of the circumstances in which the user is likely to experience a particular location or an indication of the user's subjective experience with the environment. For example, from other navigation The information received by the device may provide an indication that if, for example, a profile exhibits that a large number of users have previously erroneously followed the command at a location, the user may be in high focus at that location. In another example The server can provide information indicating that the previous user has experienced a problem with the GPS coverage in a particular area. The memory 214 can Information that can be used to determine the user's environment or the user's experience with the environment (in detail, the user's familiarity with a particular location or route), which in turn can determine the user's attention or order The level determination module 302 cooperates with the processor 2〇2 to select each of the measurement results and the data types discussed in the previous paragraphs in various modes of operation to select an instruction to be provided to the user at a particular location. Content and/or form. Each of the measurement results and the type of data affects or indicates that the user is given the attention of the instruction at a specific location and time, and/or the user at a particular location and time is very The level of instructions that may be required. An example of one of the modes of operation of the system of Figure 6 is illustrated in an overview manner in the flow chart of Figure 8. 135346.doc -28- 201015052 Various specific examples of selecting the form or content of an instruction using the system of Figure 6 depending on the context of the user environment will now be described. In an embodiment, the measuring device 3〇4 measures one or more gas-like conditions (eg, fog, rain, snow, or temperature), and the environment determining module 3〇2 determines the data from the measuring device. The value of the parameter that represents the weather condition. If the value of the parameter exceeds - or multiple thresholds, increase the number of instructions provided to the user when approaching - turn f (for example, from three to four), 参In the case of the condition, the latter may pay "the attention under normal circumstances. In the variant of this embodiment, the information about the weather condition is provided by the server 15g instead of the measuring device 3G4. In this case An additional command is provided to alert the user that he is approaching a poor weather zone. In another embodiment, the metrology device 3G4 measures ambient light and the environment determination module 302 determines a value indicative of the ambient light parameter. There are two (for example, 'representing night and daytime') or more than two (for example, nighttime - no-light road, night-lighted road; dawn; daytime) values. By commanding the control module to illuminate ambient light parameters The value of the number of instructions provided to the user regarding the route (e.g., near a turn f). For example, more instructions may be provided under low brightness conditions. Variations in this embodiment 'provided A plurality of measuring devices 304 (for example, a light sensor of the navigation device and a light sensor of the automobile) and determining the direction of the light according to the measuring devices. For example, the environment determining module 3〇2 It is determined that the user will drive into direct sunlight. The command control module 306 can issue general commands or warnings (eg, "Please wear sunglasses," please turn on the headlights") and change the instructions on the route 135346. Doc •29- 201015052 number. Instead of obtaining information from the self-measuring device 304 or in addition to the self-measuring device 3〇4, the information about the brightness condition can also be obtained from the server 150. In this case, the brightness conditions that the user may encounter may be warned in advance. For example, the user may be warned in advance that they will encounter direct sunlight on their route and instruct the user to place the sunglasses in an easily accessible location. ♦ In other embodiments, the measurement device 304 includes a sound measurement device within the carrier that measures the internal sound of the carrier. The command control module 3〇6 controls the volume of the noise input to control the volume used to provide the command and/or prior to the command, additional sound or warning tones to draw the user's attention. In variations of these embodiments, the sound measuring device is configured to detect a dialogue, for example, depending on the sound pattern and frequency. The device can be configured such that when voice or conversation is detected, the user can temporarily turn down/off the voice command by voice command or by tapping the screen. In another embodiment, when the navigation device 2 is approaching a location where the user has made a mistake in the past (eg, missed a turn), the server 15 provides the information to the navigation device 200. The information file of the information obtained by the user of the navigation device on the previous journey, in detail, is based on instructions that the navigation device must have re-routed the route at that point in the past. The environment determination module 302 determines the value of the parameter indicative of the likelihood of a user error based on the received data. If the value of the parameter exceeds a predetermined threshold, the command determination module 306 modifies the command to be provided to the user in the vicinity of the location, such as 'by alerting the user before an upcoming turn, approaching a turn Zoom display at f (zoom out or zoom in, or scale to a smaller or larger extent, early or postponed) to draw attention to the turn, or 135346.doc •30· 201015052 by approaching the turn Increase the number or volume of instructions. In other embodiments, the 'environment determination module' provides a value indicative of the user's familiarity with the location or route. In one embodiment, the environment determination module 3G2 determines the extent to which the navigation device 2 is connected to the person's home location (the home location is stored in the data repository 214). The environment module determines a value indicating the distance parameter of the home location from the location of the home, and provides the value of the parameter to the command control φ 3〇6, and the control module 306 determines whether the value of the home distance parameter is Below the predetermined threshold, and if below the predetermined threshold, most or all of the instructions to the user are suppressed, as the command may not be required if the user is close to their address. The environment determination module 302 can also determine the extent to which the navigation device 200 is close to the user's favorite location (the favorite locations are stored in the data store). The environment determination module 302 determines the distance parameter indicating the distance from the most recent favorite location. And the value of the parameter is provided to the command control module 306 306 ° & the control module 3G6 determines whether the value of the distance parameter is below a predetermined value of:: and if the value is below a predetermined threshold, the pair is suppressed Most of the user's or all & orders, because the user can know the way around them in the favorite location close to the usual place without instructions. In another embodiment, the data store 214 stores the set floor for the type of use for the user based on, for example, the time of day and the day of the week. Give it a try. The pattern is that leaving between 7am and 9am (+/- 30 minutes) on weekdays usually means that the user is going to work. After the user leaves, the environment determination module 3G2sf seeks the profile stored in the data store 214 corresponding to the time and day of the week leaving 135346.doc -31 - 201015052. If a profile matches the departure time, the environment determination module 302 provides a value of a parameter to the command selection module 3〇4, which instructs the user to select a familiar route. The command selection module 3 〇 4 suppresses commands to the user. The environment determination module 302 monitors the position of the vehicle from the output of the position determining module 3〇〇 and determines if the position matches the expected route (in this case, the route to work). If the carrier deviates from the expected route, the environment determination module 302 notifies the command selection module 306, which provides the voice command to the user 'until the carrier returns to the expected route' or until the user rejects Expect the route or enter another route. In this example, 'on the map after leaving (eg, with a dashed line, or other line than the normal route indicator) automatically displays the route from the residence to the work site, and also by the processor in communication with the server 150 Check the traffic conditions of the route. If the traffic conditions are unfavorable, the command selection module 3〇4 controls the audio or visual message to the user (as it is) and provides instructions for the alternate route. In another embodiment, the server 15 is configured to supply (e.g., obtained from the logged-in data from other navigation devices) data for the environment determination module 〇2 indicating that one of the routes has low GPS coverage. The environment determination module 302 accordingly instructs the command control module 3〇6, and in case the navigation device loses its coverage, the command control module 306 preemptively provides the user with an area for low GPS coverage before otherwise would become so. The route (for example, about a turn). It will be appreciated that in the above examples, other variations of the form or content of the user instructions may be provided in addition to or in lieu of the above variations of 135346.doc 32. 201015052, and variations or Any suitable combination.
