摘要:
A method of operating a navigation apparatus is provided. A visual or audible navigation instruction, warning or alert is provided to a user via the apparatus. The navigation instruction, warning or alert is enhanced in a continuous or stepped manner as a given location to which the instruction, warning or alert relates is approached. The instruction may be an instruction regarding a manoeuvre to be performed at a junction in order to follow a calculated route. The instruction is visually enhanced by increasing its size as the current location of the apparatus becomes closer to the junction to more readily engage the attention of the user, and to facilitate interpretation of the instruction. Alternatively a warning regarding a safety camera may be increased in size as the camera is approached.

Embodiments of the present invention relate to a route-planning device (200;302) comprising a storage section (230;308) storing map information, the map information including information identifying a plurality of potential positions, each potential position corresponding to a position at which a location of a predetermined type might potentially be found; and a search route module (490) arranged to determine a search route visiting at least one of the potential positions, the determination of the search route using a predetermined efficiency measure based on likelihood of finding a location of the predetermined type.
摘要:
A system is disclosed comprising a mobile device including at least one application which may be run on the device. The system is configured to be able to determine the geographical location of the mobile device and includes an enforcement engine that is separate to and outside of the at least one application. The enforcement engine is configured to permit or restrict a function of said at least one application on the mobile device depending on the location the device is determined to be at. The system operates to control the functioning of the application based on how the local regulations allow the application to be operated.

A system is provided that is configured to be transported, carried or worn by a user, such as a portable personal training device or sports watch. The system comprises a global navigation satellite system (GNSS) receiver arranged to obtain the location and/or speed of the user and a pedometer for counting steps made by the user. Data from the GNSS receiver is used to calibrate the pedometer each time the user is determined to travel a distance greater than a predefined distance value during a period of time in which signals obtained by the GNSS receiver meet the one or more accuracy and/or reliability criteria.

A technique is disclosed for calculating a sightseeing route from a start location to a destination location. The start location and the destination location may be the same as each other or different. The route is calculated to pass one or more attractors each representing a sightseeing attraction. A digital database resource (500) contains digital map information, the digital map information including a plurality of attractors. The technique comprises (a) determining (550) an initial route from the start location to the destination location, and setting the initial route as a current route; (b) determining (602) for each attractor in a candidate set of the attractors, a relative attraction value that is dependent on a distance between the attractor and the current route; (c) determining (604, 612) which attractor corresponds to a largest attraction value; (d) modifying (620) the current route to include a deviation to the attractor determined at step (c).
摘要:
A method of creating map data for enhancing a digital map having a plurality of navigable segments representing a network of navigable segments by applying point locations to the map which correspond to individual events on the network; generating a heat map representing the concentrations of events according to a selected distribution function; applying a threshold calculation to the heat map to identify one or more zones, on the network having a high concentration of events; and associating the or each zone with at least one segment in the digital map.
摘要:
Embodiments of the invention relate to a computer-implemented method of predicting a destination of a user of a mobile device, comprising selecting one or more geographic locations as a group of possible destinations based on a first location of the mobile device, determining a route from the first location to each of the geographic locations of the group of possible destinations according to one or more route planning criteria and digital map data, and updating the group of possible destinations based upon a second location of the mobile device and a change in an attribute of a route between the second location and each geographic location of the group of possible destinations.
摘要:
A method of determining data indicative of an individual driver workload is disclosed. The method involves obtaining a generic driver workload parameter, the generic driver workload data being based on data indicative of the behavior of multiple drivers when performing a maneuver at a node or traversing a set of one or more segments of an electronic map. An individual modifier representative of the behavior of an individual driver is generated and used to determine an individual driver workload parameter indicative of the workload of the individual driver when performing the maneuver at a node or traversing the one or more segments of an electronic map based on the generic driver workload data for performing the maneuver at the node or traversing the one or more segments of the electronic map.
摘要:
A mapping or navigation device comprises or is connectable to position determining apparatus, the position determining apparatus being operable to determine one or more locations of the mapping or navigation device, the one or more determined locations forming at least one route, wherein the mapping or navigation device is configured to determine at least one portion of the at least one route, where the at least one portion is determined according to at least one property associated with at least one location comprised in the portion, and the mapping or navigation device is configured to form at least one anonymized route from the at least one determined route, wherein the at least one anonymized route does not include the at least one portion of the at least one route.
摘要:
Embodiments of the present invention relate to a device including a module (490) which is operative in a low-power state of the device (200). The module (490) is arranged to determine whether a traffic situation on a route has more than a predetermined affect on the route, and to cause the navigation device (200) to output a notification in response thereto which alerts the user of the device to the traffic situation despite the device being in the low-power state.
