Definitions
- a modern PNDs comprises a processor, memory (at least one of volatile and non-volatile, and commonly both), and map data stored within said memory.
- the processor and memory cooperate to provide an execution environment in which a software operating system may be established, and additionally it is commonplace for one or more additional software programs to be provided to enable the functionality of the PND to be controlled, and to provide various other functions.
- PND devices of this type also include a GPS antenna by means of which satellite-broadcast signals, including location data, can be received and subsequently processed to determine a current location of the device.
- the PND is enabled by software for computing a “best” or “optimum” route between the start and destination address locations from the map data.
- a “best” or “optimum” route is determined on the basis of predetermined criteria and need not necessarily be the fastest or shortest route.
- the selection of the route along which to guide the driver can be very sophisticated, and the selected route may take into account existing, predicted and dynamically and/or wirelessly received traffic and road information, historical information about road speeds, and the driver's own preferences for the factors determining road choice (for example the driver may specify that the route should not include motorways or toll roads).
- the device may continually monitor road and traffic conditions, and offer to or choose to change the route over which the remainder of the journey is to be made due to changed conditions.
- Real time traffic monitoring systems based on various technologies (e.g. mobile phone data exchanges, fixed cameras, GPS fleet tracking) are being used to identify traffic delays and to feed the information into notification systems.
- PNDs of this type may typically be mounted on the dashboard or windscreen of a vehicle, but may also be formed as part of an on-board computer of the vehicle radio or indeed as part of the control system of the vehicle itself.
- the navigation device may also be part of a hand-held system, such as a PDA (Portable Digital Assistant) a media player, a mobile phone or the like, and in these cases, the normal functionality of the hand-held system is extended by means of the installation of software on the device to perform both route calculation and navigation along a calculated route.
- PDA Portable Digital Assistant
- An icon displayed on-screen typically denotes the current device location, and is centred with the map information of current and surrounding roads in the vicinity of the current device location and other map features also being displayed. Additionally, navigation information may be displayed, optionally in a status bar above, below or to one side of the displayed map information, examples of navigation information include a distance to the next deviation from the current road required to be taken by the user, the nature of that deviation possibly being represented by a further icon suggestive of the particular type of deviation, for example a left or right turn.
- the navigation function also determines the content, duration and timing of audible instructions by means of which the user can be guided along the route. As can be appreciated a simple instruction such as "turn left in 100 m" requires significant processing and analysis.
- user interaction with the device may be by a touch screen, or additionally or alternately by steering column mounted remote control, by voice activation or by any other suitable method.
- a further important function provided by the device is automatic route recalculation in the event that: a user deviates from the previously calculated route during navigation (either by accident or intentionally); real-time traffic conditions dictate that an alternative route would be more expedient and the device is suitably enabled to recognize such conditions automatically, or if a user actively causes the device to perform route re-calculation for any reason.
- a route to be calculated with user defined criteria; for example, the user may prefer a scenic route to be calculated by the device, or may wish to avoid any roads on which traffic congestion is likely, expected or currently prevailing.
- the device software would then calculate various routes and weigh more favourably those that include along their route the highest number of points of interest (known as POIs) tagged as being for example of scenic beauty, or, using stored information indicative of prevailing traffic conditions on particular roads, order the calculated routes in terms of a level of likely congestion or delay on account thereof.
- POIs points of interest
- Other POI-based and traffic information-based route calculation and navigation criteria are also possible.
- route calculation and navigation functions are fundamental to the overall utility of PNDs, it is possible to use the device purely for information display, or "free-driving", in which only map information relevant to the current device location is displayed, and in which no route has been calculated and no navigation is currently being performed by the device. Such a mode of operation is often applicable when the user already knows the route along which it is desired to travel and does not require navigation assistance.
- a navigation device may be part of a hand-held device capable of handling telephone calls i.e. receiving incoming calls and making outgoing calls, such as a PDA or mobile phone.
- a navigation device may be associated with a device capable of receiving incoming calls, such as a mobile phone, via a connection which enables the navigation device to support a hands-free use of the mobile phone to receive the incoming call.
- a navigation device may connect with a mobile phone over a wireless data connection such as Bluetooth to provide the hands-free operability of the mobile phone via the navigation device.
- a wireless data connection such as Bluetooth
- Yet another embodiment of the present invention relates to computer software comprising one or more software modules operable, when executed in an execution environment, to cause a processor to perform a method of handling a telephone call comprising receiving a telephone call at a navigation device; determining a cognitive workload of a user of the navigation device; and determining a response to the call based at least in part on the cognitive workload.

- a navigation device 200 may be associated with a device capable of handling telephone calls in a number of ways.
- the navigation device 200 may include its own mobile phone technology, such as a SIM card, or the navigation device may be included within a mobile phone.
- the navigation device 200 may have established a data connection with the mobile phone, for example over a wireless interface such as Bluetooth.
- the navigation device is capable of providing hands-free functionality for the mobile phone i.e. receiving the person's speech and outputting audio from a phone call established with the mobile phone.
- the navigation device may alert the user of the incoming call and allow the user to answer the call through interaction with the navigation device.
- Figure 6 illustrates a mobile telephone 610 which is associated with a navigation device 620.
- the mobile phone 610 is illustrated as being a discrete device from the navigation device 620, as mentioned above, the two may be an integrated device.
- the mobile phone 610 of Figure 6 is connected via a wireless communication channel 630 to the navigation device 620 to enable communication there-between.
- the wireless communication channel 630 may, for example, be a Bluetooth communication channel.
- the mobile phone 610 and navigation device 620 exchange various data over the communication channel 630.
- the mobile phone 610 provides status information to the navigation device 620, such as indicating whether the mobile phone 610 currently receives a signal from a telecommunications network with which it is associated.
- the navigation device 620 may display on its display screen 240 indicators relating to some or all of the status information received from the mobile phone 610. Other data, such as contact information, may also be communicated to the navigation device 620 from the mobile phone 610. The navigation device 620 may communicate to the mobile phone 610 user generated instructions relating to the operation of the mobile phone 610 which are received by the navigation device 620 from the user. For example, as shown in Figure 6, in a sub-menu or GUI screen of the navigation device 620, one or more controls 621 , 622 relating to the operation of the mobile phone 610 are displayed.
- the user may perform operations of the mobile phone 610, such as making a call, answering an incoming call, viewing contact information from the user's address book, etc. Furthermore, the mobile phone 610 may communicate incoming call information to the navigation device 620 so that the navigation device 620 may alert the user to the call.
- the navigation device 620 may display information identifying the caller such as name retrieved from the user's address book if the number of the incoming caller is known. The navigation device 620 may alert the user to the incoming call visually and/or audibly.
- the mobile phone 610 and navigation device 620 exchange audio data relating to the voices of those participating in the call.
- Embodiments of the present invention involve the determination to a cognitive workload of a user of the navigation device.
- the cognitive workload of a person is a measure of a mental load of that person.
- the cognitive workload may be thought of as the "busyness" of the person i.e. how much of the person's attention is currently being utilised. Determining the cognitive workload of the person may involve consideration of one or many factors which each, to a greater or lesser degree, consume some portion of the person's cognitive capacity.
- the ACHM 490 determines the cognitive workload of the user of the navigation device 620 based upon one or more criteria and handles a telephone call according to the determination.
- An incoming call may be handled in one or more ways, such as the user not being alerted to the call through to the user being alerted to the call as normal.
- An outgoing call may be handled in a similar manner. The user may be totally prevented from making outgoing calls, or outgoing calls may only be permitted to some destinations.
- the ACHM 490 determines the handling of the call according to the cognitive workload of the user and information associated with the call such, as an identification of the caller or called person.
- the method 700 begins and in step 710 a call is received.
- a call is received.
- an incoming call will be described, although embodiments of the invention may also relate to outgoing calls.
- the navigation device 620 is notified of the incoming call by the mobile phone 610 via the communications channel 630 such that the ACHM 490 becomes aware of the incoming call.
- the mobile phone 610 may also communicate data associated with the call to the navigation device 620 such as caller information.
- the caller information may be a number of the calling party and/or other identification information such as a name associated with the calling number which is stored in the mobile phone 610.
- the ACHM 490 may determine information associated with the number from a phone book stored in the memory of the navigation device 620.
- the cognitive workload of the user is determined.
- the cognitive workload of the user may be determined by the ACHM 490 according to many factors.
- the cognitive workload of the user may be determined by the ACHM 490 as a cognitive score.
- the cognitive workload of the user is determined by the ACHM 490 in some embodiments according to one or more of: a speed of movement of the navigation device 620, which may be determined by the ACHM 490 or another module of the navigation device 620 from the received GPS signals; a location of the navigation device 620; a time of day at which the call is received; current traffic and/or weather conditions, although this list is not exhaustive.
- the location of the navigation device 620 may affect the cognitive workload of the user in many ways.
- the location of the navigation device 620 may be determined with respect to a geographic locality of the navigation device 620. For example, a locality classification may be used to identify locations as one of a plurality of predetermined location categories, such as "urban, semi-urban or rural", although this list is not exhaustive. If the location of the navigation device 620 is identified as being "urban”, then the cognitive workload of the user according to the location may be given a high cognitive score, whereas if the location corresponds to "rural” then the cognitive workload may be scored relatively low. This is because it is expected that when travelling in an urban environment more of the user's attention is required to avoid accidents.
- the cognitive workload of the user may also or alternatively be determined with respect to the current location and one or more aspects of a route being followed by the navigation device 620.
- Figure 8 illustrates a route 800 for which the navigation device 620 is providing route guidance between a start location 810 and a destination location 850.
- Intermediate points 820, 830, 840 indicate locations at which route guidance is provided to the user, for example at junctions, lane changes etc. along the route 800.
- a current location of the navigation device 620 along the route 800 is indicated with symbol 860.
- the ACHM 490 may determine the cognitive workload of the user based on the location 860 of the navigation device 620 with respect to a distance between the current location 860 and a next upcoming route guidance location, in the present case location of symbol 830. If the distance is less than a predetermined threshold, e.g.
- the cognitive workload may be given a relatively high score as it is expected that the user will shortly be relatively busy dealing with the upcoming route guidance 830, such as taking a turn off from a current road segment.
- the ACHM 490 may determine the cognitive workload of the user with respect to a distance of the current location 860 from either the start or destination locations 810, 850 of the route.
- the cognitive workload may also be determined with respect to the current location and one or more user defined geographic areas, such as area 870.
- the user may identify geographic areas which are defined to have a high cognitive workload for many reasons, such as the user finding these areas particularly difficult to travel through.
- the ACHM 490 determines a relatively high cognitive workload score of the user.
- the time of day may affect the cognitive workload of the user. For example, when driving at night i.e. during darkness the user may require more attention and thus the ACHM 490 may determine a relatively high cognitive score according to this criterion during hours of darkness.
- 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 influence the cognitive workload since in an area of high traffic the user may be more occupied and thus the ACHM 490 determines a higher cognitive score.
- the ACHM 490 determines a relatively high cognitive score as the user is likely to require more attention being expended on travelling in those conditions.
- a classification of the calling party may be determined.
- Some mobile phones allow the user to assign contacts stored in the phone book to one or more predetermined categories or groups.
- contacts stored in the memory of the navigation device 620 may be assigned to one or more groups.
- Groups may be, typically, “friends”, “work”, “boss”, “spouse”, “friends A”, “friends B”, etc although these groups are merely exemplary.
- Each group may have one or more contacts assigned to that group and contacts are not necessarily limited to being assigned to only one group.
- each group has an assigned caller value, such as a numeric value between 1 and 10 or 1 and 100, although these ranges are merely exemplary.
- the caller value indicates the importance or likelihood that the user wishes to speak to the caller. For example, members of "spouse” or “boss” may be assigned a relatively high caller value indicating that it is likely that the user wishes to speak to that caller, whereas "friends B" may be a group of less well known friends and thus are assigned a relatively low caller value.
- step 730 does not require each caller to be assigned to a group, individual callers may have their own caller value assigned i.e. groups may consist of only one caller.
- a response to the incoming call is determined.
- the response may be selected from one or more predetermined call responses.
- the call response is determined according to one or more rules, which may be determined by the user. For example, a rule may indicate that if the speed of the vehicle is over a predetermined speed, such as 80kmh "1 , then a predetermined call response should be selected. Similarly, if the call takes place during the hours of darkness and/or the distance to an upcoming route guidance location is less than a predetermined distance a predetermined call response may be selected. Rules may be combined to take into account a plurality of conditions, such as speed greater than Y kmh "1 and within an urban location then select a predetermined response.
- the response may be selected according to the cognitive workload score determined in step 720. For example, a predetermined call response may be selected if the cognitive workload score is over a value X or between values Y and Z.
- the response may be selected in step 740 according to, at least in part, the classification of the caller.
- the rules may indicate that above a predetermined speed incoming calls should receive a first response, unless the caller is, for example, "spouse" who would receive a second response.
- the response may be selected according to a combination of the cognitive workload value and the caller value.
- the call response may be selected according to the equation:
- R is the call response
- W is the cognitive workload value
- C is the caller value.
- the importance of the caller counteracts the cognitive workload, where higher values of R select call responses which are less likely to require attention from the user. If the caller identity is unknown i.e. originates from an unknown number, then the caller may be assigned a very low caller value.
- the call response relates to the handling of the call i.e. the direction of the call.
- an incoming call may either be rejected, such that the user is not alerted, alerted to the user only visually, alerted to the user normally i.e. audibly and visually, or redirected to another destination such as to an answer phone, or to a selected one of one or more other numbers, such as to a colleague of the user in the case of the caller being a member of group "work".
- the ACHM 490 may accept the call but may only allow one-way communication between the caller and user.
- navigation device 620 may indicate to the user that the call has been automatically answered, but may then only allow mono-directional communication between the user and the caller i.e. only allow the caller to hear the user so that the user may verbally indicate that they are busy and to call back later.
- the ACHM 490 is arranged to answer the call i.e. without user involvement.
- a response to the call may be provided by the ACHM 490.
- the response may dynamically include information associated with the navigation device 620.
- the ACHM 490 may respond to the call by providing information associated with the user of the navigation device 620.
- the information may be a location or a current speed of the navigation device 620, information identifying a start and/or destination location of the navigation device, or any other information indicative of circumstances associated with the navigation device 620.
- the ACHM 490 is equipped with a speech synthesis capability to respond verbally to the caller.
- the verbal response provided to the caller by the ACHM 490 may be geo-coded i.e. based upon geographic and/or route information of the navigation device 620.
- Some responses provided to callers may indicate the location of the navigation device 620, such as "Thank you for calling. Mike cannot take your call now as he is engaged driving though Manchester", where the name of the user is stored in their user profile on the navigation device 620 and the location is determined by the ACHM 490 according to the received GPS signals.
- the ACHM 490 may respond to the incoming call with a verbal response based on the current location of the navigation device and the route being followed, such as "Thank you for calling. Mike cannot take your call now as he is engaged driving and will arrive in Wakefield in approximately 12 minutes".
- One embodiment of the invention may base, at least partly, the verbal response upon data stored in a database accessible to the navigation device 620 such as a database accessible over the communications channel 318 with the server 302.
- the ACHM 490 may retrieve data associated with the caller from the database and provide the verbal response based thereon, the location of the navigation device 620 and the route being followed.
- the ACHM 490 determines the identity of the caller from data associated with the incoming call, then retrieves information about the caller from the database, in particular the location of the caller in order to determine an expected time of arrival at the caller's location along the route. The ACHM 490 then responds with, for example, "Thank you for calling. Mike cannot take your call now as he is engaged driving. However, your delivery will arrive at your location at approximately 14:50.” It will be appreciated that a variety of geo-coded (providing details of the location of the navigation device) verbal responses may be provided to callers and those described above are merely exemplary.
- the ACHM 490 may also handle outgoing calls according to embodiments of the method shown in Figure 7, except the call is received from the user i.e. requesting to make a call. In these cases the ACHM 490 may determine in step 740 whether to allow the outgoing call based on one or both of the cognitive workload of the user, as determined in step 720, or the classification of the called person, as determined in step 730.
- the ACHM 490 not allow a call to any persons to be made if the speed exceeds, for example, 80kmh "1 , whereas the ACHM 490 may allow calls to be made to a person having an assigned importance greater than a predetermined level when the speed is between 50 kmh "1 and 80kmh "1 .
- the one or more rules to determine the call response in step 740 to an outgoing call may be set by the user, as for incoming calls.
- the response to the call determined by the ACHM 490 may include a visual component.
- the visual component may be one or more still images, or a moving image i.e. a video.
- the navigation device 620 may be associated with one or more cameras.
- the cameras may form part of the navigation device 620, or may be formed within a vehicle carrying the navigation device 620 wherein the navigation device 620 is capable of receiving images from the cameras i.e. over a communication channel with the vehicle.
- a camera may be arranged to have a user of the navigation device 620 within its field of view, such as a driver of the vehicle.
- a camera may be arranged to capture surroundings of the navigation device 620, such as a forward view of the navigation device showing, for example, the road ahead of the navigation device 620. It will be a realised that one or more cameras may be arranged to capture any desired view.
- the response may include the visual component showing, for example, the user of the navigation device 620 i.e. driver of the vehicle and/or the forward view of the navigation device 620 i.e. showing the road ahead.
- the visual component may include information associated with the route guidance, if any, being provided by the navigation device 620 i.e. showing the caller an icon associated with upcoming route guidance being provided to the user of the navigation device.
- the ACHM 490 may also shown on the display screen of the navigation device 620 an image, still or video, of the caller. The visual component may thus communicate the current situation of the user of the navigation device 620, particularly to a person calling the user.
- the visual component may be communicated as a still or video image as a multimedia message service message (MMS) or as a video connection with the mobile telephone 610.
- MMS multimedia message service message
- the visual component may then be displayed on a display screen of the mobile phone 610.
- step 750 the response to the call determined in 750 is made by the ACHM
- embodiments of the invention allow a customised, dynamic, response to be provided to calls according to a cognitive workload of the user and, in some embodiments, the identity of the calling or called person.
- one or more of the cognitive scores associated with factors in step 720, the caller values used in step 730 and the rules-base and the determination of one or more call responses used in step 740 may be determined by the user.
- the user may program a user profile stored on the navigation device 620 either by direct interaction with the navigation device 620 or via a computer communicatively coupled to the navigation device 620.
- the settings of the navigation device may only be set by an administrator or similar having particular privileges to stop, for example, users who are employees configuring the navigation device 620 to allow calls at any time etc.
- a navigation device associated with a mobile telephone may handle calls according to a cognitive workload of the user.
- calls may be prevented, partially allowed in a variety of different forms or redirected according to the cognitive workload, such that the user is not distracted, particularly at times of high cognitive workload.
- the identity of the caller in part determines the response to the call.
- the navigation device may utilise any kind of position sensing technology as an alternative to (or indeed in addition to) GPS.
- the navigation device may utilise using other global navigation satellite systems such as the European Galileo system. Equally, it is not limited to satellite based but could readily function using ground based beacons or any other kind of system that enables the device to determine its geographic location.
