Description

Method and system for assisting with task management and navigation

The invention relates to the assistance for the management of the tasks of a user and the navigation aid to perform these tasks.

Document US2006 / 0058948 discloses a system for assisting a user in the organization of tasks. In this system, each task is associated with a geographic location. The system makes it possible to determine a path making it possible to link all the locations associated with these tasks. This system is not entirely satisfactory because the user does not control the path determined by the system.

The invention therefore aims to provide a method and a system for assisting a user to determine a path whose setting by a user is improved.

It proposes more precisely for this purpose a navigation assistance method implementing a telematic system of a vehicle, comprising the following steps:

obtaining and storing (21), in a memory of the system, a list of ordered tasks, each task comprising at least one title and possibly a geographical location,

the determination (22), for each task of the list without geographical location, of at least one geographical location associated with said task, from the title of the task,

- The determination of a path (23) connecting the geographic locations associated with each task, the order of geographical locations on the determined path being identical to the order between the tasks.

- The simultaneous display (24) of the ordered list and the determined path.

With the invention, a user controls the order in which the tasks are arranged on the path. Indeed, it imposes the order of the tasks, which allows a better setting of the determined path.

In addition, the invention determines a path including with tasks whose location is not filled by a user. Indeed, the invention allows to determine locations automatically from a heading describing a task.

The determined route makes it possible to optimize one or more trips and offers the user the opportunity to save money (time, money, or 5 others ...) by optimizing the route between these locations, taking into account for example traffic related information (or any other relevant information (s) for the user, for example fuel consumption, type of routes used, total price of the journey, etc.).

Advantageously, if at least one task is associated with a plurality of locations, the method further comprises a step of selecting a location for determining the path, the selection being made from a predetermined criterion chosen from: minimizing the distance traveled, minimizing travel time or the number of parking spaces available near the location.

Advantageously, the system comprises a table associating keywords at predetermined locations. The step of determining at least one geographical location associated with a task includes: searching in the title of the task of keywords present in the table, and,

) - if a keyword is identified in the title, then the association with said task of the predetermined locations corresponding to the identified keyword.

Advantageously, the system comprises a geolocated task history, the step of determining at least one geographical location associated with a task comprises: an analysis of the task's title to determine whether it comprises at least one expression used in a title of one or more geolocated task (s) stored in the history and, if for each task of the identified history, the association with the task of the location (s) (s) ( s) of the task identified in the history. Advantageously, the method further comprises a step of obtaining a modification of the list made by a user and, in response, the execution of the steps of determining a path and displaying taking into account the list of modified tasks.

Advantageously, the method further comprises a step of guiding the user from the determined path.

The invention also relates to a navigation assistance system comprising nomadic equipment and a telematic system connected to a telecommunication box on board a vehicle, characterized in that it further comprises: means for obtaining and storing, in a memory of the system, a list of ordered tasks, each of the tasks comprising at least one title and possibly a geographical location, means for determining, for each task in the list 5 without geographical location, d at least one geographic location associated with said task, from the title of the task, means for determining a path connecting the geographical locations associated with each of the tasks, the order of the geographical locations on the determined path being identical to the order between the tasks, means for simultaneously displaying the ordered list and the determined path, on a telematics system or nomadic equipment.

Advantageously, the system further comprises means for selecting a location for the tasks associated with several locations, the selection being made from a predetermined criterion chosen from: minimizing the distance traveled, minimizing the travel time or the number of parking spaces available near the location.

) Advantageously, the system further comprises means for obtaining a modification of the list of tasks performed by a user.

Advantageously, the system further comprises means for guiding the user from the determined path.

Other features and advantages of the invention will become apparent upon consideration of the following detailed description, and the accompanying drawings, in which:

FIG. 1 illustrates an example of a system for implementing the method according to the invention;

FIG. 2 shows a diagram illustrating the method according to the invention;

FIG. 3 shows an exemplary interface of the system according to the invention.

The attached drawings may not only serve to complete the invention, but also contribute to its definition, if any.

Figure 1 shows an example of a system for implementing the method according to the invention. Such a system 10 includes equipment

5 nomad 1 1, a telematic system 13 connected to a telecommunication box 12 on board a vehicle 16.

The nomadic equipment is for example a smartphone (or smartphone), a tablet, a computer or an electronic key. This nomadic equipment 1 1 comprises at least one processor (or CPU for

) Central Processor Unit), display means (such as a screen), designation means (for example a touch screen, a designator, a mouse, a keyboard, a remote control, a voice recognition module and / or gesture or a module for monitoring eye movements, also known as eye-tracking). The nomadic equipment 1 1 also includes

5 means of communication with a remote network 14, such as the Internet, comprising shared computing resources. These communications means are, for example, a type 2G / 3G / 4G telecommunications network connection, and / or means of communication with the on-board telematics platform 13 in the vehicle 16, by

example of Wifi type, Bluetooth or Near Field Communication or NFC for Near Field Communication. Nomadic equipment 1 1 optionally includes a geo-positioning system using satellites 15 GPS type for Global Positioning System.

The telecommunication box 12 integrated in the vehicle 16 comprises communication means (Wifi, Bluetooth, 2G / 3G / 4G type telecommunications network connections, satellite positioning, etc.) for

On the one hand, establish a communication between the on-board telematics system 13 and the nomadic equipment 1 1 and, on the other hand, to establish a communication between the on-board telematic system 13 and the remote network 14. Access to the network remote 14 makes it possible to collect the data transferred by the user from the mobile equipment 1 1, or any data

) on which the system is based for the calculation or representation of useful information to the user (download maps, data type traffic information, etc.).

Figure 2 shows a diagram illustrating the method according to the invention.

The navigation assistance method according to the invention comprises a step of obtaining and storing, in a memory of the system 10, a list of ordered tasks, each task comprising at least one title and possibly one geographical location.

These tasks are entered by a user using one of the means of designations previously described for example on the mobile device 1 1 or on the telematic system 13. The tasks can also be downloaded from the remote network 14.

By entering the tasks to be performed, the user can choose to specify (or not) an address corresponding to one or more tasks to be performed. The user can enter addresses, from the mobile equipment 1 1 and / or from the telematics platform 13 embedded in the vehicle16, at the same time that it captures tasks to be performed.

The navigation assistance method also comprises a determination step 22, for each task of the list without geographical location, of at least one geographic location associated with said task, from the task title. The system includes a task geolocation module. This module implements at least one of the methods described below.

A first method implements a table, stored in a memory of the system 10, associating predetermined expressions (for example "refueling") with geolocated points of interest (representing

Eg service stations). The memory of the system 10 can be located in the on-board telematic system 13, or in the mobile equipment 1 1, or in a remote server connected to the remote network 14. The module analyzes the job title to determine whether the latter has one of the predetermined expressions. Where applicable, points of interest

) geolocated associated with the detected expression are associated with the task including the analyzed title. For example, it is assumed that the system has a table in which the expression "bread" is associated with points of interest corresponding to bakeries and / or supermarkets. If a non-geolocated job has a "buy bread" heading, then the

The system associates with this task the locations of the corresponding points of interest stored in the table.

A second method implements a history preserving geolocated tasks. The module analyzes the title of the task to determine if it contains at least one expression already used in one or more geolocated task (s) stored in the history. In this case, the non-geolocated task is associated with the location (s) of the task (s) found in the history.

Preferably, the task geolocation determination module implements a preference base that maintains

5 preferences associated with a user, the locations determined by the module being filtered using retained preferences. For example, it is assumed that the user has completed a "refuel" task and that the module has determined several service stations and supermarkets to be associated with this task. If the user has entered in these preferences a

) A particular fuel distribution sign (with which it has a loyalty card for example) then the module filters the locations so as to offer the user only the service stations of this sign. More generally, the module can transfer the title of the task to a suggestion system accessible by the remote network 14 and able to offer feedback suggestions location.

For example, the system 10 can access a social network to determine an address of a person to locate a task related to that person.

If at least one task is associated with a plurality of locations, the method further comprises a step of selecting a location for determining the path, the selection being made from a predetermined criterion chosen for example from: minimizing the distance traveled, minimizing travel time (estimated using road traffic data) or the number of parking spaces available near the location.

The method also comprises a step of determining a path 23 connecting the geographical locations associated with each of the tasks, the order of geographical locations on the determined path being identical to the order of the tasks in the list.

This step implements conventional route calculation methods between a starting point, an end point and intermediate steps imposed by a user.

Figure 3 shows an example of display on a screen of the system according to the invention. This display comprises a first graphic object 31 representing the list of tasks selected by the user. Preferably, this graphic object 31 is interactive and makes it possible to add and / or delete a task from the list. It also makes it possible to modify the order of the tasks in the list for example by drag-and-drop.

The system therefore comprises means for modifying the order of the tasks in the list. The system also includes means for adding and / or deleting one or more tasks from the list. The order and number of tasks in this list directly leads to a calculation of a route.

According to one embodiment of the invention, the display comprises a indication, for example a color code, for associating the steps of the journey with the tasks of the list. In this case, each task in the list has a different color. Each point of the path has the same color as the task with which it is associated.

The display also includes a second graphical object 32 representing a map as well as the path determined by the system. The path includes as many intermediate points as selected tasks in the list. The order of these intermediate points is identical to the order of the corresponding tasks in the list. These points are identified by a descriptive label

) for example "Fournil Opera".

If the user changes the order of the tasks in the list, in response the system automatically determines a new path taking into account the user-defined task order.

The map thus makes it possible to visualize the geolocalised tasks retained in the list for calculating the route and the path described by this route.

Advantageously, a graphic indication makes it possible to estimate the constraints related to traffic density information (or any other relevant information or information for the user or for calculating the route) .

Advantageously, the display also comprises other graphic objects indicating information on the user's environment (for example a third graphical object indicating the weather), or giving access to multimedia content (for example a fourth graphic object 34 broadcasting a radio program)

The navigation assistance method also includes a step of guiding the user from the determined path. The guidance 25 comprises the determination and the emission of visual and / or sound messages indicating the route to be followed to the user.

The guiding step 25 is either executed in response to an action of

) the user, is executed automatically for example when the vehicle 16 starts or when it moves. For this purpose, the system according to the invention includes means for collecting and interpreting information from the sensors of the vehicle. In this way, the system 10 can determine for example if the speed of the vehicle is greater than 0 km / h and, if necessary, perform the guiding step).

Other functions can be automated in the same way, for example the blocking, during the driving phase, of access to certain functionalities deemed dangerous (or prohibited by the legislation in force in the country of broadcast).

The invention thus makes it possible to display on the same screen, geo-localized tasks and the location of these tasks on a map. This information can be consulted on a mobile device 1 1 or on any other system with which a communication will be established, including the telematic system 13 on board the vehicle 16. The system can thus present in a single screen on the one hand the guidance of the system of

15 GPS navigation, on the other hand information related to any other type of event that may occur in or around his vehicle (interactions with the embedded multimedia system, notifications or alerts from computers or other equipment of the vehicle, etc. .), or any other type of event that may occur around the user during

20 use of the system.
