Description

201200396 * VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a navigation device and a method for handling a telephone call by a navigation device. Illustrative embodiments of the present invention relate to portable navigation devices (so-called PNDs), and more particularly, PNDs that include Global Positioning System (Gps) signal reception and processing functionality. Other embodiments are more generally directed to any type of processing device that is configured to execute navigation software to provide route planning functionality and preferably also provide navigation functionality. [Prior Art] A portable navigation device (PND) including GPS (Global Positioning System) signal receiving and processing functionality is well known and widely used as an in-vehicle or other transportation navigation system.

~~灿% Ί王吣1S body and at least one of the non-volatile memory, and usually both, and the map data stored in the memory. The processor cooperates with the memory to provide a -execution environment in which a software operating system can be built, and additionally 'often provided' or multiple additional software programs to enable the functionality of the PND to be controlled and provide various other functions. . Usually, 'there are more than one person who interacts with the device and controls the "multiple wheeled interfaces, and/or multiple output interfaces, which are buried by the - or multiple output interfaces." 'You can write the information in two. Illustrative examples of the input interface and the input interface for the audio output include the on/off physical buttons for (4) off operations or other features (if the device is built in 152417.doc 201200396 Inside the 'Shai special button is not necessarily on the device itself, but on the steering wheel, and on the steering wheel, and the microphone for detecting the user's words. In a particularly preferred configuration In the middle, the output interface can be configured as a touch-sensitive display (by means of a touch-sensitive overlay or in the form of a cooker) to additionally provide an input interface, through the input interface, The device can be operated by touch to the user. This type of device will also often include: _ or multiple physical connector interfaces, through which the power signal and the situation can be A data signal is transmitted to the device and receives power signals and conditional data signals from the device; and, as the case may be, or multiple wireless transmitters/receivers, which allow for cellular telecommunications and other signals and Feed network (e.g., wiFi,

Communication over Wi-MaxGSM and similar networks. This type of PND device also includes a _ GPS ρ GPS antenna with which the satellite satellites including location data can be received and subsequently processed to determine the current location of the device. The apparatus may also include an electronic gyroscope (gy) that generates a signal and an accelerometer 'can number that can be processed to determine the current angular acceleration and linear acceleration' and in combination with position information from the GPS ticker to determine the device And thus the speed and relative displacement of the vehicle on which the device is installed. Typically, these features are most commonly provided in the transport satellite (four) navigation system, but may also be provided in the PND device (if this is advantageous). The utility of such PNDs is primarily manifested in their ability to route between the first position (usually the starting or current position) and the second position (usually the destination). Such locations may be entered by the user of the device by any of a wide variety of different methods of 152417.doc 201200396, for example, by postal code, street name and house number, previously stored "familiar a ^ ^ The door has no destination, such as a famous location, a municipal location (such as a stadium ice skating pool) or other points of interest, and a favorite or recently visited destination. The pass PND is provided with a function m for calculating the "best" or "best" route between the start address position and the destination address position based on the map data, or based on predetermined criteria. Not necessarily the fastest or shortest route. The choice of route to guide the driver can be very complex, and the selected route can take into account existing, predicted, and/or wirelessly received traffic and road information, historical information about road speed and 51_ The self-preference for determining the factors of the road alternative (9) such as '51 machine can be routed μ including highway or toll road). ▲In addition, the device can continuously monitor roads and traffic conditions, and provide or choose to change routes due to changing conditions, on which the remaining journey will take place. An instant traffic monitoring system based on various technologies (example #, mobile phone data exchange, fixed camera, GPS fleet tracking) is being used to identify traffic delays and feed information into the notification system. This type of PND can usually be installed on the dashboard of the transport guard or on the windshield. It can also be formed as part of the onboard computer of the transport radio or as part of the control system of the transport guard itself. The navigation device can also be part of a handheld system, such as a pDA (10) tape type digital assistant, a media player, a mobile phone, or the like, and in such cases, the conventional functionality of the handheld system is by installing the software. The route calculation is performed on the device with 152417.doc 201200396 and the navigation along the calculated route is expanded. Route planning and navigation functionality can also be provided by desktop or subscription computing resources that execute appropriate software. For example, the Royal Automobile Club (rac) is in the online route planning and navigation facility, which allows the user to type in the starting point and destination, so the server is connected to the server to calculate the route (the aspect can be The user specifies, generates a map, and produces a detailed set of navigation instructions for directing the user from the selected starting point to the selected destination. The facility also provides pseudo three-dimensional rendering and route preview functionality for the calculated route. The route preview functionality simulates the user traveling along the route and thereby provides the user with a preview of the calculated route. In the case of a PND, once the route is calculated, the user interacts with the navigation device to select the desired calculation from the list of proposed routes, as appropriate. Depending on the situation, the user may intervene or (4) the route selection process, for example, by specifying a route for a specific journey, which should be avoided or must follow certain routes, roads, locations or criteria <· PND. And navigation along this route is another major function. During the navigation of a calculated route, these PNDs often provide a perceptual and/or sonar command to point the user along a selected route. At the end of the Xuan route, Φ is the desired destination. The PND is also often used during the navigation period: the map information is displayed on the screen, and the information is regularly 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 transportation vehicle ( If the device is being navigated with ^ in the transport). , 152417.doc 201200396 The icon 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, depending on the situation, the navigation information may be displayed in a state bar above, below or on one 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 nature of the deviation. This property may be represented by a different icon indicating a particular type of deviation (eg, a left turn or a right turn). The navigation function also determines that the content, duration, and timing of the voice commands can be used to guide the user along the route. As you can see, simple instructions such as "left turn after 100 m" require a lot of processing and analysis. As previously mentioned, the interaction of the user with the device can be by touch screen, or (in addition or otherwise) by a lever mounted remote control, by voice activation or by any other suitable method. Another important function provided by the device is that the automatic route is again different in the following cases. The user deviates from the previously calculated route (3) during the navigation or intentionally prompts the traffic condition indication - the alternative route will be more favorable and 5 The Hai device can properly identify these conditions, or when the user actively "executes the route recalculation for any reason." It is also known to allow the calculation of routes according to user-defined criteria; for example,

The user may prefer the scenic route calculated by the device, or may wish to avoid any traffic that may be caused by traffic jams, is expected to occur, or is currently occurring. The device software will then calculate the various routes and prefer to include along the route with the highest number of routes labeled as, for example, a point of interest with a view (called P〇I) or use to indicate the traffic conditions that are occurring on a particular road. 1524I7.doc 201200396 Store information, sort the route according to the possible blockage or the delay due to blockage. Other route-based and navigation criteria based on Pm and traffic information are also possible. 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", in which only map information related to the current device location is displayed, and wherein the route has not been calculated and The device does not currently perform 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 type described above (e.g., 720 制 manufactured and supplied by T〇mT〇m Intemati〇nai bv) provide a reliable means for enabling a user to navigate from one location to another. As mentioned above, a navigation device can be part of a handheld device (e.g., a PDA or mobile phone) capable of handling a telephone call (i.e., receiving an incoming call and making an outgoing call). Alternatively, a navigation device can be coupled via a connection to a device capable of receiving an incoming call, such as a mobile telephone, the connection enabling the navigation device to support the mobile telephone from receiving the hands-free use of the incoming call. For example, a navigation device can be coupled to a mobile telephone via a wireless data connection (such as Bluetooth) to provide hands-free operability of the mobile telephone via the navigation device. However, even a mobile phone may not be completely secure, as it has been observed that merely maintaining a telephone conversation (even via hands-free) can lead to distractions. It is an object of the present invention to provide a navigation apparatus and method that can handle an incoming call in an improved manner. SUMMARY OF THE INVENTION To achieve this goal, a presently preferred embodiment of the present invention provides a device comprising a navigation device, the navigation device comprising means for receiving a telephone call and configured to One or more criteria determine a cognitive workload of a user and determine a module to respond to one of the calls based at least in part on the cognitive workload. Another preferred embodiment of the present invention provides a method of handling a telephone call, comprising: receiving a telephone call at a navigation device; determining one of the users of the navigation device to recognize a workload; and based at least in part on The 5^ knowledge workload determines the response to one of the calls. Yet another embodiment of the present invention is directed to a computer software comprising one or more software modules operable to cause a processor to perform a method of handling a phone call when executed in an execution environment, the method comprising Receiving a telephone call at a navigation device; determining that one of the users of the navigation device recognizes a workload; and determining to respond to one of the calls based at least in part on the cognitive workload. The advantages of the embodiments are set forth below, and further details and features of each of these embodiments are defined in the accompanying sub-claims and elsewhere in the following embodiments. [Embodiment] Various aspects of the teachings of the present invention and the configuration of the teachings of the present invention are described by way of illustrative example. The preferred embodiment of the present invention will now be described with particular reference to a PND. However, it should be borne in mind that the teachings of the present invention are not limited to PNDs, but are generally applicable to any type of processing device that is configured to execute navigation software to provide route planning and navigation functionality 152417.doc 201200396. Thus, it can be seen that, in the context of the present application, the navigation device is intended to include, but is not limited to, any type of route planning and navigation device, whether the device is embodied as a PND, a navigation device built into the vehicle, Or actually embodied in computing resources that implement route planning and navigation software (such as desktop or portable personal computers (PCs), mobile phones, or portable digital assistants (PDAs)). With the above conditions in mind, the figure 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-based 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, previously referred to as navstar. A plurality of satellites orbiting the earth in orbit. Based on these precise orbits, the GPS satellite can relay its position to any number of receiving units. The GPS system is implemented when the device that is used to receive GPS data is started to scan the RF for GPS signals. After receiving a radio signal from a satellite, the device lightens the precise position of the satellite via a plurality of different conventional methods. In most cases, the device will continue to scan the signal until it has acquired at least three different satellite signals (note that 'other triangulation techniques can be used to determine position by only two signals, although this is a very rare example) . After performing the geometric triangulation, the receiver uses its three known positions to determine its own two-dimensional position relative to the satellite. This determination can be made in a known manner. In addition, acquiring the fourth satellite signal will allow the receiving device to calculate its three-dimensional position in a known manner by homo-geometric calculation 152417.doc •10·201200396. The position 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 number I 。. A plurality of satellites 120 are in orbit around the earth 124. The doctrine of each satellite is not necessarily synchronized with the orbits of other satellites 120, and is actually likely to be different. The GPS receiver 140 is shown receiving a spread spectrum GpS satellite signal 160 from various satellites 120. 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 the particular satellite 120 as part of its data signal transmission. Those skilled in the relevant art will appreciate that the GpS receiver device 140 typically acquires a spread spectrum Gps satellite signal "^ for at least three satellites 12" for the GPS receiver device 14 to calculate its two-dimensional position by triangulation. The acquisition of the extra lift number, which causes the signal 160 from a total of four satellites i 2 , permits the GPS receiver device 140 to calculate its three-dimensional bitmap in a known manner as a preferred implementation of one of the present invention in a block component format.

The navigation device 620 can display an indication received on the display screen 24G from the mobile phone (4). Other information, such as some or all of the relevant information of the contact status information, may also be communicated from the mobile phone 610 to the navigation device 62. The navigation device 62G can communicate the user-generated instructions relating to the operation of the mobile phone 6iq to the mobile phone 610, which commands are received by the navigation device 620 from the user. For example, as shown in FIG. 6, in the sub-menu or GUI screen of the navigation device 62, - or a plurality of control items 621, 622 related to the operation of the mobile phone 61 () are displayed. Using these controls 621, 622, the user can perform operations such as making an incoming call, viewing contact information from the user's address book, and the like. In addition, the mobile phone 610 can communicate the incoming call information to the navigation device (4) such that the navigation device 620 can alert the user to the call. If the caller's number is known, then the navigation device 620 can display the identity of the caller, such as the name retrieved from the subscriber's address book. The navigation device 62 can alert the user to the incoming call in a visual and/or audible manner. Finally, during a call, the mobile phone 610 and the navigation device 62 exchange audio data relating to the voices of the individuals participating in the call. Embodiments of the present invention include determining the cognitive work of the user of the navigation device. The human beings know that the workload is a measure of the mental load on the person. In the sense of the present invention, the cognitive workload can be regarded as the "busy" of the person, that is, the extent to which the attention of the person is currently being utilized. Determining a person's cognitive work may include consideration of one or more factors, each of which is a greater or lesser part of the cognitive ability of the person. In an embodiment of the invention 'ACHM 490 determines the cognitive workload of the user of navigation device 620 based on one or more criteria and handles the telephone call based on the determination. The call can be handled in a variety of ways, such as J52417.doc • 21-201200396, for example, the call is not alerted to the user until the user is normally alerted that the call 4i can be handled in a similar manner. The user can be completely blocked from making an outgoing call, or only an outgoing call to some destinations. In some embodiments, the ACHM 49 determines the handling of the call based on the user's cognitive workload and information associated with the call, such as identification of the caller or callee. A method 700 in accordance with an embodiment of the present invention will now be described with reference to FIG. Method 700 begins and a call is received in step 71. As a real illusion, 彳田 speaks an incoming call, but embodiments of the present invention may also be associated with an outgoing beer. In the case where the mobile phone 61 is separated from the navigation device 62 (i.e., communicated via the communication channel 630), the mobile phone 61 notifies the navigation device 62 via the communication channel 630 that the incoming call is made so that the attention is drawn. B tongue calls t). The mobile phone 61 can also communicate information associated with the call, such as caller information, to the navigation device 620. The caller information can be the caller's number and/or other identifying information, such as the name associated with the calling number stored in the mobile phone 610. In the case where the number of the calling party is communicated to the navigation device 620, the aCHM 49 can determine the information associated with the number of the phone book from the memory stored in the navigation device 620. In step 720, the cognitive workload of the user is determined. ACHM 49〇 The cognitive workload of the user can be determined based on a number of factors. The achm 490 can determine the cognitive workload of the user as a cognitive score. In some embodiments, the ACHM 490 determines the cognitive workload of the user based on one or more of the following: the speed of movement of the navigation device 62, which may be 152417.doc • 22-201200396 by the navigation device 620 The ACHM 490 or another module determines based on the received gps signal; the location of the navigation device 620; the time of day at which the call was received; the current traffic and/or weather conditions, but this list is not exhaustive. Some of the factors involved in determining cognitive workloads will now be explained in more detail. The location of the navigation device 620 can affect the cognitive workload of the user in a number of ways. The location of the navigation device 620 can be determined with respect to the geographic area of the navigation device 62. For example, a location classification may be used to identify a location as one of a plurality of predetermined location categories (such as "city, semi-city, or rural" 'but this list is not exhaustive. If the location of the navigation device 62 is identified as "City" can give the user a high cognitive score based on the cognitive workload, and if the location corresponds to "rural", the cognitive workload can get a relatively low score. This is because it is expected to travel in an urban environment. It is necessary to determine the user's cognitive workload. Alternatively, or alternatively, the user's cognitive workload may be determined with respect to the current location and the route along which the navigation device is located. A route 8 between the location 810 and the destination location, the navigation device 620 provides route guidance for the route. The intermediate point 820 830, 840 refers to a location that does not provide directions to the user along the route, such as ' Convergence, lane change, etc. The current position of the navigation device is indicated by the symbol 860. In the current position of the symbol, the ACHM 490 can be based on navigation. Location of the coffee shop 86〇About the position of the previous position _ and the next-to-one route guidance position (4) (4) The decision of the (4) cognitive 胄 胄 1 The distance is less than a predetermined 1524I7.doc •23· 201200396 A value (e.g., 1 km) can give the cognitive workload a relatively high score because the user is expected to be relatively quick to cope with the upcoming route guidance 830, such as turning away from the current road segment. Similarly, ACHM 490 may determine a cognitive workload of the user with respect to a distance of the current location 860 from either the departure location 810 or the destination location 850 of the route. The current location and one or more user-defined geographic regions may also be determined The cognitive workload is determined (such as region 870). The user can identify geographic regions that are defined as having high cognitive workload for a number of reasons, such as the user finding that such regions are particularly difficult to pass. When location 860 is defined by the user In the area 870, the ACHM 490 determines the user's relative south cognitive work score. The time of day may affect the user's cognitive work. Load. For example, when driving at night (i.e., during the night), the user may need more attention, and therefore, the ACHM 490 may determine a relative cognitive score based on this criteria during nighttime. In an embodiment, the ACHM 490 may determine the cognitive workload of the user with respect to traffic and/or weather conditions at the current location 860 of the navigation device 620. Traffic may affect cognitive workloads because in areas with large traffic volumes, users It may be more busy, and therefore, the ACHM 490 determines a higher cognitive score. Similarly, at a location that experiences one or more predetermined types of weather conditions (such as high winds, heavy rain, freezing, snowing, etc.), the ACHM 490 determines Relatively high cognitive scores, as users are likely to need to pay more attention to their situation. Returning again to Figure 7, in optional step 730, the caller's points can be determined 152417.doc -24- 201200396 The empty call-on phone allows the user to store the call in a predetermined category or group. Alternatively or additionally, the contacts stored in the navigation device 620 may be assigned to one or more group groups, which may be "friends", "guards", "Boss", "spouse", friends", "friends", etc., but these groups are merely illustrative. Each group may have one or more contacts assigned to the group, and the contacts are not necessarily limited to being assigned to only one group. In some embodiments, each group has a value of - assigned caller value 'such as between ... and ι , but such ranges are merely exemplary. The caller value indicates the importance or likelihood that the user wishes to speak to the caller. For example, a member of a "spouse" or boss may be assigned a relatively high caller value indicating that the user is likely to wish to speak to the caller, while "friends" may be a group of friends who are less familiar. And therefore a relatively low caller value is assigned. Of course, step 730 does not require that each beer be assigned to a group of individuals: individual callers may have their own assigned caller value, i.e., each group may consist of only one caller. In step 740, a response to the incoming call is determined. The response can be selected from - or ^ fixed reservation call response. In some embodiments, the call response is determined based on - or a plurality of rules that are determinable by the user. For example - the rule may indicate that if the speed of the vehicle exceeds a predetermined speed (such as 80 kmh'' then a predetermined beer call response should be selected. Similarly, if the call occurs during the night and/or is off - coming soon If the distance of the route guidance location is less than - the predetermined distance, a predetermined call response may be selected. The rules may be combined to consider a plurality of conditions (such as a speed greater than γ kmh·, and a location step in the domain 152417.doc •25·201200396) And selecting - predetermined μ m fortune, the response can be selected based on the cognitive defensive load score determined in 720. For example, if the cognitive workload score exceeds the value or is between the value 丫 and 2, then A predetermined call response. In an embodiment of the invention comprising step 730, at step 74, the response may be selected based, at least in part, on the classification of the caller. For example, the rule may indicate an over-predetermined speed, The incoming call should receive the first response, unless the caller is, for example, receiving the second response. "The spouse is widely available in some embodiments, based on the cognitive workload value and Combination values are called in response to select - in some embodiments, may be selected according to the beer should call back the following equation.

R = W-C where the call response is known to the workload value and C is the caller value. As can be seen, the importance of the caller offsets the cognitive workload, with higher choices being less likely to require a user's attention to the call response. If the identity of the caller is unknown (i.e., 'from an unknown number'), the caller can be assigned a very low caller value. In some embodiments, the 'call response' is defamatory with the handling of the call (i.e., the direction of the call). For example, the incoming call can be rejected such that the unarmed user only visually alerts the user to the incoming call, alerting the user to the incoming call in a normal manner (ie, in an audio and visual manner), or In the future, the call is redirected to another-destination (such as redirecting to the answering machine) or redirected to one of the one or more other numbers (such as 'Working in the caller's group" In the case of a member, redirect to 152417.doc -26· 201200396 one of the users of the colleague). In some embodiments, the ACHM 49 may be called, but may only allow one-way communication between the caller and the user. For example. The navigation device 620 can indicate to the user that the call has been automatically answered, and then only one-way communication between the user and the caller can be allowed, that is, only the caller can hear the user, so that the user can indicate the delicious head. It is busy and will call back later. However, in other embodiments, the ACHM 49 is configured to answer the call 4, i.e., does not involve the user. In such embodiments, the response to the call may be provided by achm 490. The response can dynamically include information associated with the Xiao navigation device 620. In other words, the ACHM 49 can respond to the call by providing information associated with the user of the navigation device 620. The information may be the location or current speed of the navigation device 620, information identifying the departure and/or destination location of the navigation device, or any other information indicative of the environment associated with the navigation device 62A. In such embodiments, the ACHM 49G is equipped with a speech synthesis capability to make a verbal response to the caller. The verbal response provided by the ACHM 49A to the caller may be geocoded, i.e., based on the geographic and/or route information of the navigation device 62. Some of the responses provided to the caller may indicate that the navigation device "❹i" is such as "Thank you shirt, y caU now as he is engaged driving though, where the user's name is stored in its navigation The device is located in the user profile and the location is determined by the ACHM 49〇 based on the received GPS signal. Alternatively, the ACHM can be used to make an incoming call based on the current location of the navigation device and the verbal response of the route followed, 152417.doc •27· 201200396, such as "Thank you for calHng. Mike cannot take your call now As he is engaged dfiv^nS ^nd will arrive in Wakefield in approximately 12 chutes. An example of the present invention allows the verbal response to be based at least in part on a database that is accessible by the navigation device 620 (such as The data in the database accessed via communication channel 318 with server 302. In some embodiments, 'ACHM 490 can retrieve information associated with the caller from the database and provide a verbal response based on the material, The location of the navigation device 620 and the route followed. For example, where the cargo driver follows one of the one or more destination routes, the ACHM 490 determines the identity of the caller based on the information associated with the incoming call. Then, from the database, the pre-payment of the caller’s stipulation (specifically, the location of the caller) to the location of the caller along the route is determined. Time. ACHM 49〇 then use (for example) "771 (10) moxibustion less (10) for calling. Mike can take your call now as he is engaged driving. However, your delivery will arrive at your /ocaiz.ow approximately 74:50." . It should be appreciated that 'a variety of geocoded (providing details of the location of the navigation device) can be provided to the caller, and the verbal response described above is merely exemplary. In some embodiments of the invention, the ACHM 490 may also handle the outgoing call in accordance with an embodiment of the method illustrated in Figure 7, except that the call is received from the user (i.e., the user requesting the call). In this case, 'ACHM 490 may be based on the user's cognitive workload (as determined in step 720) or the called person's classification (as determined in step 730) in step 740 152417.doc • 28 · 201200396 One or both determine if an outgoing call is allowed. For example, if the speed exceeds, for example, 80 kmh·1, the ACHM 490 does not allow a call to anyone's and the speed is between 5. Kmh·丨 and 8. The two-person two 490 between kmh and 可 may allow a call to be made to a person having an assigned importance greater than a predetermined level. As with the incoming call, one or more of the rules for determining the call response to the outgoing call in step 74 can be set by the user. In some embodiments of the invention, the response to the call as determined by the ACHM 49A may include a - visual component. The visual component can be - or a plurality of still images or a moving image (i.e., video). The navigation device 62 can be associated with one or = cameras. The cameras may form part of the navigation device 620 or may be formed in a vehicle carrying the navigation device 620, wherein the navigation device 620 can (i.e., via a communication channel with the vehicle) receive images from the cameras . The camera can be configured to cause the user of the navigation device 62 (e.g., the driver of the vehicle) to be within its field of view. Alternatively or additionally, the camera can be configured to capture the surroundings of the navigation device 62, such as a view of the navigation device, which displays, for example, a road ahead of the navigation device 62. It should be recognized that one or more cameras can be configured to capture any desired view. When the ACHM 490 determines a response to the beer in step 74, the response may include displaying, for example, the visual component of the user of the navigation device 620 (i.e., the driver of the vehicle) and/or the navigation device 62 To the view (that is, to show the front road ahead view). Additionally, in some embodiments, the visual component includes: 贞Λ φ associated with the route guidance provided by the guidance device 620 (if present), ie, 'to the caller' - and to the user of the navigation device The icon associated with the upcoming route guide. In some embodiments, i524J7.doc -29-201200396, the ACHM 490 can also display the caller's image (static or video) on the display of the navigation device 62. The visual component can thus convey the current situation of the user of the navigation device 620 to, in particular, the person calling the user. Vision Knife 1: can be communicated as a multimedia message service message (mms) as a static or m-image or as a video link to a mobile phone and then can display a visual component on the display screen of the mobile phone 61. In v 750, the response to the call that was taken at 750 by the ACHM 490 is performed. As mentioned above, embodiments of the present invention allow dynamic responses to snoring based on the cognitive workload of the user and, in some embodiments, the identity of the caller or the called person. In order to manage embodiments of the present invention, one or more of the following may be determined by the user: the cognitive score associated with each factor in the step, the caller value used in step 73, and the step 740 The basis of the rules used and the determination of the response to one or more squeaks. For example, the user can program the user profile stored on the navigation device 62Q by directly interacting with the navigation device 62 or by a computer that is connected to the navigation device 620 in a manner of 5 through. In some embodiments, for example, for a commercial user of the navigation device 62, the navigation device may only be configured by an official or with certain privileges to prevent, for example, the user of the employee from configuring the navigation device 620 to allow A similar person setting such as a call at any time. As is apparent from the foregoing, the teachings of the present invention provide a configuration by which the navigation device associated with the mobile phone can handle the call based on the user's perceived workload. Therefore, it can be blocked according to the cognitive workload. I52417.doc -30- 201200396 The call is partially allowed to call or redirect the call in a number of different forms, so that the user is not distracted, especially when there is a high cognitive workload. Further, in some embodiments, the identity of the caller partially determines the response to the call.
