Description

- 1 - Interactive navigation system and method implemented in this system

TECHNICAL FIELD The present invention relates to a navigation system and method for the use in particular of a pedestrian or a vehicle user.

PRIOR ART Prior art is known in the prior art of navigation devices using the GPS (Global Positioning System) network comprising a GPS receiver making it possible to locate in real time the position of the device, by reference to certain satellites of the GPS network. and a database for storing in particular mapping data, so that the device can be located at any time on a map. Such devices are programmable by a user, in particular a motor vehicle driver, to guide him during a journey from a starting point to an arrival point. The disadvantage of such a device is that the user must program himself a route objective on the navigation device. This programming is sometimes quite long. The user must generally be able to name their purpose, which may require prior research, then enter an entire street and city name. For safety reasons, it is therefore not possible to program a route objective on the navigation device without stopping his vehicle momentarily. In addition, when a user is not in possession of a specific address, but simply in search of a particular point of interest, for example a restaurant meeting his criteria, the navigation device turns out insufficient.

There are navigational devices having in memory a series of points of interest classified by type. These devices are nevertheless limited, both by the number of points of interest that can be stored, as well as by the amount of additional data that can be stored on these points of interest, and by the frequency with which these data are updated. The object of the present invention is to provide a system and a method implemented in this system, not having the drawbacks mentioned above.

SUMMARY OF THE INVENTION This object is achieved with a navigation system, in particular for the use of a pedestrian or a vehicle user, comprising: at least one navigation terminal equipped with geolocation means and means for providing the user with guidance information up to a route objective; a server equipped with at least one database having access to local and / or remote information sources; bidirectional communication means between the server and the at least one navigation terminal; 15 and in which a route objective is programmable on the at least one navigation terminal, from the remote server, in response to a request from the user, and wherein the navigation terminal rolls up guidance information to to the scheduled route goal from the server. Thus, a route objective is programmable on the at least one navigation terminal, from the server, in response to a request from the user. The server may be driven by a human operator that takes into account the user's request, makes or initiates a search, and then transmits the search result as a route objective via the server. In addition or alternatively, the server preferably comprises means for calculating an optimum route objective according to different criteria. A user preferably sends via the navigation terminal, to the server, a request for a route objective belonging to a category (for example restaurant, museum, service station, etc.) and preferably corresponding to at least a criterion chosen by the user. This at least one criterion is for example the proximity of the current position of the navigation terminal, the proximity of a favorite address, the proximity of the arrival point or any point of the current route on the terminal of navigation. A criterion can also be negative, for example to avoid a given place. The criterion (s) may include the quality, price and / or ambience of a desired route objective, particularly in the case of finding a restaurant, bar, etc. In response to this request from the user, the server selects a route objective by human search and / or by means of calculating at least one optimal route objective. In addition to a criterion chosen by the user when he asked the server to receive a route objective, criteria such as culinary tastes, preference between small roads or major axes, etc. can be in memory in the server for each user, and systematically taken into account during a route objective calculation, without the user having to recall it systematically. The consideration of systematic criteria may result from an initial data entry by the user, and / or automatic learning. The systematic criteria may also be stored in the navigation terminal and automatically transmitted to the server together with the solicitation of a route objective. The selection of a route objective in the server can also take into account the history of the navigation terminal, preferably stored in the server, that is to say recently and / or often frequented places. The server then remotely programs on the requesting sender's navigation terminal, a route objective, and the navigation terminal then calculates and unpacks visually and / or vocally the guidance information to that purpose. Preferably, the navigation terminal comprises remote payment means. According to a preferred embodiment, the user once records his bank data, which are then used for each payment. Remote payment is made securely. In particular, the remote payment means make it possible to pay for a reservation with a service provider via the navigation terminal. In case of theft of the navigation terminal, the stolen user reports the theft to an administrator, then the administrator deactivates the means of payment at a distance to prevent fraudulent use of the navigation terminal, and through identification parameters. of the navigation terminal. In addition, the fact that the navigation terminal is equipped with geolocation means makes it possible to quickly find the location of a declared stolen or mislaid navigation terminal. In addition, a subscription to different services offered by service providers, via the navigation terminal, may also be blocked by an administrator in the event of a flight declaration from the navigation terminal. Preferably, the solicitation of the user includes a request for recommendation of a point of interest, in particular among a restaurant, a car park, an airport, a garage, a hospital, a public transport stop, toilets, a terminal self-service bicycles, a space to change a young child, a rest area, a gas station etc. Points of interest may relate to a pedestrian and / or a vehicle user. According to a preferred embodiment, the server is in contact with at least one service provider capable of providing updated information. Preferably, it is directly the at least one server database that is related to this at least one service provider. In this case, the service provider sends information directly to the at least one database of the server. Another possibility is that at least one service provider database is a remote source of information to which the server has access. The exchange of data between the server and the at least one service provider is done according to the HTTP protocol (HyperText Transfer Protocol) and / or in XML (Extensible Markup Language).

Preferably, the server is in contact with at least one service provider in such a way that the user of a navigation terminal can communicate with the service provider via the server, for example to make a reservation with the service provider. service provider. On a request from the user, the server can select a service provider, connect the terminal with the service provider, and transmit to the terminal the route objective where the chosen service will be delivered to service providers. Access to service of a service provider is preferably managed by a subscription. The exchange of data between the server and at least one navigation terminal, as well as between the server and at least one service provider, is either automatic or generated in a desired manner. An example of automatic data exchange may be the sending of geolocation data to the server by the navigation terminal. An example of data exchange in a desired manner is for example the sending of a request by a user, from a navigation terminal, and to the server.

The at least one service provider preferably comprises at least one of the service providers among a carpool service, a weather monitoring service, a traffic monitoring service, a car park availability monitoring service, a car park service and a car service. tracking the price of gas in different stations, a contact service with a hostess. Thus, the user of the navigation terminal has information both very rich and very recent on many points of interest. The at least one service provider makes available on at least one database located directly in the server and / or remotely, a lot of information on each point of interest that is preferably updated in real time. For example, it is possible to know in real time the dish of the day of a restaurant, the availability at every moment of parking, the local weather and in particular the local fog, ice and / or snow, offers and / or carpooling requests, the location of slowdowns and track work, the accessibility of a point of interest to persons with reduced mobility, etc. In addition, the user of the navigation terminal can access via the server to a contact service with a hostess (male or female). Preferably, the hostess has access to specific parameters relating to the navigation terminal held by said user, such as the history of speeds and routes and / or personal data indicated by the navigation terminal user. The hostess allows for example the user to place an order. The user sends the hostess a purchase and / or reservation request, in particular a purchase of an airline ticket, a train ticket, a reservation of a parking space, etc.

The hostess performs a search, preferably taking into account at least some of the specific parameters relating to the requesting navigation terminal, and / or common general parameters that may concern any navigation terminal. The hostess then informs the user, via the navigation terminal, the result of the search, obtains the final choice of the user. The hostess, or directly the choice of the user triggers the reservation and / or the purchase. The hostess may also be responsible for selecting for the user a route objective, instead of this selection being made by calculation in the server. The hostess also makes it possible to make a call for the user of the navigation terminal, or to put him in touch with certain services, in particular a breakdown service, or legal advice. Preferably, the server sends several route objective proposals to the navigation terminal, from which the user chooses one or no route objective to be programmed on the navigation terminal. Thus, the user is not obliged to accept the first route objective programmed on his navigation terminal. Preferably, a first route objective is proposed to the user of the navigation terminal, who can then choose to accept this first proposal or to request a second one. All route objective proposals are sent at the same time to the navigation terminal, or one by one depending on the positive or negative response of the navigation terminal user to the proposal sent from the server. The user can take note of all the proposals sent from the server on the navigation terminal, and then choose one of them. According to a preferred embodiment, the navigation terminal comprises a local memory for storing at least cartographic data which will in particular make it possible to carry out the guidance up to the programmed route objective from the server. In addition, the local memory can store other information such as specific parameters, in particular the history of the navigation terminal, personal data of the user of said navigation terminal, identification data which enables the server identify a particular navigation terminal, etc.

Preferably, the at least one database of the server is able to store specific parameters corresponding to each navigation terminal, as well as common general parameters. The specific parameters corresponding to each navigation terminal include the history of the geolocation data, personal data recorded by the user of the navigation terminal, such as birthday dates, culinary preferences, favorite addresses. The specific parameters are also for example identification parameters of a navigation terminal. Common general parameters include map data, but also dates and times of events such as Mother's Day, Christmas, but also movie releases, book releases, election days, etc. . For this, the server preferably comprises an internal clock. The at least one database is preferably queried by the server according to the SQL (SQL query language). Preferably, the server takes into account at least some of the specific parameters corresponding to the navigation terminal, to determine a route objective to be programmed. Preferably, the server takes into account at least some of the common general parameters to determine a route objective to be programmed. Among the common general parameters that the server can take into account in determining a route objective to be programmed, it is also possible to count traffic, weather, and other information. This information is provided by at least one service provider. Thus, among the service providers, there are those which provide common general parameters such as traffic and weather conditions, and those which provide very specific services which are not advantageously taken into account in the calculation of the data. an optimum route objective, such as contacting a hostess, a detailed list of hospital locations, restaurants, etc. According to a preferred embodiment, the at least one database of the server comprises two-way communication means with at least one additional communication terminal. Preferably, the communication is via a web portal, preferably with the HyperText Transfer Protocol (HTTP) and / or HTTPS (HyperText Transfer Protocol Secured). The auxiliary communication terminal is preferably a fixed or portable computer. The user of a navigation terminal can thus set his registered user account on the at least one database of the server, from the auxiliary communication terminal. The user account includes specific parameters relating to a navigation terminal, preferably the personal data of the user, and / or the list of service providers whose user wishes to receive the services. A new user of a navigation terminal can also register on the server via the ancillary communication terminal, instead of registering directly via his navigation terminal. He also has access to an after-sales service via the communication terminal. It is also possible for resellers of navigation terminals, in partnership with the company producing the navigation terminals, to manage stocks of navigation terminals. In addition, data stored in the at least one database of the server can preferably be transferred to the ancillary communication terminal via the bidirectional communication means. The additional communication terminal also allows administrators to have access to the at least one database of the server, in particular to manage the different subscriptions to the service providers. In addition, simple visitors may also have access to certain information available on the server, in particular to enable them to discover the associated navigation system. These may be potential users of navigation terminals, or representatives of potential service providers in relation to the server. Preferably, the server is capable of communicating announcements to the navigation terminal according to specific parameters corresponding to said navigation terminal, in particular geolocation data of the navigation terminal, and / or according to common general parameters, to invite the navigation terminal. user to request from the server the programming of the navigation terminal of this user with a route objective that is related to said advertisement. Ads can be sent as SMS (Short Message Service) and / or MMS (Multimedia Messaging Service). For example, the server can propose to a user, via the navigation terminal, to make a detour by a flower vendor, if the internal clock of the server indicates that it is the day of the Mother's Day recorded in the parameters common general, or a birthday day saved in the specific settings of the user. When the navigation terminal passes close to a certain shop, the server preferably sends the navigation terminal an invitation to go through this shop, invitation for example accompanied by a promotional offer. When the internal clock of the server indicates a meal time, the server sends to the navigation terminal, according to another example, an invitation to lunch at a nearby restaurant. When the user makes long journeys, for example on motorway, the server sends at regular intervals, for example every two hours, announcements to invite the driver to take a break on a rest area, preferably by proposing to each once a single area, and an area equipped with more services such as a gas station. The user is free either to refuse the proposal or to accept it and then send the server a request for the navigation terminal to be programmed with a route objective in connection with the invitation. In the case where the same server is common to several navigation terminals located in different time zones, the server comprises means for calculating the time and date at the location where a navigation terminal is located, from the time and date indicated by its internal clock. According to a variant of this embodiment, the time and / or date are available directly on the navigation terminal, and sent in real time to the server, in the same way as the geolocation data. The navigation terminal is preferably portable, light enough and compact to be slid into a pedestrian's pocket. The navigation terminal may preferably be fixed inside a vehicle, for example on the inner face of the front windshield, for example by fitting into a removable support located at this location. Thus, said navigation terminal can be used by a vehicle user being held in the removable support, then by a pedestrian being detached from the removable support. The navigation terminal can also be integrated in a vehicle, for example by being directly part of the dashboard. The navigation terminal preferably comprises a battery or any other means of autonomous power supply, in particular for use in pedestrian mode. When used in a vehicle, particularly a motor vehicle, the power of the navigation terminal can be connected directly to the vehicle, for example connected to a power supply, in particular a cigarette lighter. The navigation terminal is equipped with geolocation means, in particular a GPS receiver. It can thus be located in real time on a map. In addition, the positioning data of the navigation terminal preferably makes it possible to calculate the speed and / or heading (direction and direction of movement) of the navigation terminal. Here at least geolocation data are called positioning data, preferably accompanied by speed and / or heading. In the case where the navigation terminal is momentarily in a zone deprived of a GPS signal, for example inside a tunnel, positioning algorithms preferably make it possible to estimate the instantaneous position of the navigation device. navigation. The calculation of the speed, the heading of the navigation terminal, and / or the estimation of its position in the event of a momentary absence of GPS signal, can be carried out directly within the navigation terminal and / or remotely, from preference in the server. The navigation terminal further comprises means for calculating a path from a known starting point, preferably the instantaneous location of the navigation terminal, to a route objective, as well as means for communicating with the destination. navigation terminal user guidance information to the route objective. The server is located remote from each of the navigation terminals. It has access to local information sources, i.e. information stored directly in the at least one database included in the server, and to remote information sources, ie that is, stored preferably in at least one database outside and outside the server. The navigation system comprises two-way communication means between the server and at least one navigation terminal. The communication between the server and at least one navigation terminal is preferably GPRS (General Packet Radio Service) and / or GSM (Global System for Mobile Communications). Thus, the navigation terminal sends to the server in real time its geolocation data which are preferably used to calculate the speed, the heading and / or the estimate of the position of the navigation terminal. The navigation terminal may further communicate to the server the arrival point and the route of a guidance in progress. The server preferably sends to the navigation terminal proposals for route objectives, but also for example general information such as a Mother's Day reminder, and map updates for example. According to a preferred embodiment, the navigation terminal is equipped with a man-machine interface, in particular a touch screen and / or voice recognition means. Preferably, there is provided an on-screen menu selection page, on which there are several pictograms each corresponding to a different service, in particular - access to the configuration of the user account, access direct to the connection with a hostess, access to a type of data corresponding to a particular service provider (for example a pictogram for the solicitation of the programming as a route objective, a free parking, a pictogram for the solicitation of the program as a route objective, a carpooling offer, etc.). The term "menu" here refers to the menus of software installed in the navigation terminal. A pictogram is preferably chosen thanks to the touch screen, a screen that then makes it possible to navigate between various other menus. According to a preferred embodiment, the navigation terminal includes a close-up display mode, so as to allow its use by visually impaired persons. According to a variant of this embodiment, the navigation terminal is equipped with buttons and / or a keyboard on which a user presses to enter an address, navigate from one pictogram to another, etc. Preferably, the man-machine interface comprises voice recognition means. Thus, it is possible for the user to send information and / or requests to the server, in a simple manner, without the need to read small characters adapted to the small size of the navigation terminal, and without the need for concentration. special. The navigation terminal preferably comprises a microphone, as well as a loudspeaker. Thus, the information to be transmitted to the user, whether guidance information, or announcements sent by the server, can be either directly read on the screen of the navigation terminal, or heard through the speaker. Preferably, the navigation terminal comprises means for adjusting the sound, in particular the volume. The human-machine interface also preferably allows a user to enter and save information on the navigation terminal in an electronic notebook, for example an aisle and a parking floor to find a vehicle parked in a parking lot. underground.

The navigation terminal preferably comprises means for storing its geolocation coordinates at a given moment, so that these stored coordinates can subsequently be taken as an objective, in particular for the user to find the parking space of his vehicle. Geolocation coordinates are preferably known as positioning coordinates, as well as, optionally, a heading and a direction, for example to know in which direction and therefore on which side of the track a vehicle is parked. Another possible solution to find a parked vehicle is also to call the service of communication with a hostess, who has access to the history of the navigation terminal 5 and can see where the navigation terminal began to be used in pedestrian mode, which corresponds for example to the exit of a user out of his vehicle after parking. The hostess has access in particular to the speed history, or to a history of the power modes of the navigation terminal, a battery power supply 10 may correspond to a pedestrian mode, while a power supply for example on a power supply an electric vehicle can correspond to a vehicle mode. According to a preferred embodiment, the server identifies a navigation terminal when it is switched on, thanks to the identification parameters stored in the at least one database of the server and / or in the navigation terminal. Preferably, the server is able to receive from each navigation terminal information relating to a speed control point, then to transmit an alert to any navigation terminal approaching this control point within a certain time, after the reception. some information. The speed control point can be fixed or mobile. The presence information of a speed control point is preferably sent by a user having identified said checkpoint. Preferably, the server processes the various information relating to a speed control point so as to eliminate the erroneous information by statistical analysis. The invention also relates to an interactive navigation method in which geolocation data of a navigation terminal held in particular by a pedestrian or a vehicle user, are regularly transmitted to a server, the method comprising at least the following steps: the user sends to the server, from a navigation terminal, a search request for a point of interest defined by a category and specified by at least one criterion; the server selects a point of interest corresponding to the request and remotely programs the navigation terminal with a route objective corresponding to the selected point of interest, for the navigation terminal to guide the user according to the a possible route to the point of interest. In order to select a point of interest, the server preferably takes into account parameters specific to the navigation terminal transmitting the request, in particular navigation location geolocation data, and / or personal data relating to the terminal holder of the terminal. navigation. The server can also take into account common general parameters to select a point of interest. According to a preferred embodiment, the server contacts a service provider to select the point of interest.

DESCRIPTION OF THE FIGURES AND EMBODIMENTS Other advantages and particularities of the invention will appear on reading the detailed description of implementations and non-limiting embodiments, and the following appended drawings: FIG. 1 is a view in perspective of a navigation terminal according to the invention, - Figure 2 schematically illustrates a navigation system according to the invention, - Figure 3 illustrates an embodiment of the navigation system according to the invention, - Figure 4 illustrates a first example of a graphical interface that can be viewed on the navigation terminal; -Figure 5 illustrates a second example of a graphical interface that can be viewed on the navigation terminal; and -Figure 6 illustrates a navigation system according to the invention comprising the communication of announcements, from the server, to the navigation terminal. The navigation system 4 according to the invention (FIG. 2) comprises at least one navigation terminal 1 equipped with geolocation means and means for providing the user with guidance information up to a route objective. The means for providing guidance information comprises a touch screen 2 (FIG. 1) and a loudspeaker 3. The navigation system 4 comprises a server 5 (FIG. 3) equipped with a database 6, and means for two-way communication between the server 5 and the navigation terminals 1. The two-way communication between the server 5 and each of the navigation terminals 1 is represented in FIGS. 2 and 3 by the arrows 7. The communication is bidirectional because the 8 of a navigation terminal 1 can send to the server 5 information at a time to record in the database 6 specific parameters which correspond inter alia to parameters of a user account stored in the server 5 , as well as requesting a route objective recommendation, and the server 5 can send to the navigation terminal 1 in particular a route objective. Indeed, a route objective is programmable on a navigation terminal 1 from the remote server 5, in response to a request from the user 8 of said navigation terminal 1. The navigation terminal 1 thus programmed then unwinds information. guidance to the objective programmed from the server 5. An exemplary method associated with the navigation system 4 according to the invention implements the following steps: the user 8 sends to the server 5, from the terminal of navigation 1, a search request for a point of interest, called a request, defined by a category (example: restaurant) and specified by at least one criterion 20 such as the simplicity of access, the proximity of the instantaneous location the navigation terminal 1, etc .; the server 5 selects a point of interest corresponding to the request, by using parameters such as the instantaneous location of the navigation terminal 1 to determine an optimal route objective, and remotely offers the user 8 this optimal route objective; the user 8 sends back to the server 5 information indicating that he accepts the proposal, refuses this proposal and requests another, or refuses any proposal; after the user has accepted a proposal, the server remotely programs the navigation terminal 1 with a route objective corresponding to the selected point of interest; the navigation terminal 1 guides the user 8 along a possible path towards the point of interest. The server 5 is in contact with a number of service providers 9, which provide it with up-to-date information. The communication between the server 5 and each service provider 9 is represented by the arrows 10. The arrows 10 are bidirectional. A service provider 9 sends updated information to the server 5, while the server 5 can communicate to the service providers information, for example 5 relating to the users 8 subscribed to the services of the service provider 9 via the navigation system 4. , the user 8 of the navigation terminal 1 is in at least indirect relation with the service providers 9, via the server 5. It is for example possible for the user 8 to make a reservation with 10 of one of the service providers 9. The service providers 9 typically include a carpool service, a weather monitoring service, a traffic monitoring service, a car park availability monitoring service, a price monitoring service. gasoline at different stations, and / or a contact service with a hostess. The contacting service with a hostess allows the user 8 to be put in contact with a human person. The choice of a route objective to be programmed on the navigation terminal 1 of the user 8 can then be performed by this human operator, man or woman. The database 6 is able to store specific parameters, which correspond to each navigation terminal 1, and common general parameters. The specific parameters are, for example, birthday dates, the user's tastes, the geolocation data history corresponding to his navigation terminal 1, and so on. The 25 common general parameters are for example national holidays, but also cartographic data. The database 6 may also contain the locations of the speed controls and the server 5 may transmit to the navigation terminals 1 the triggering of an alert each time a navigation terminal 1 approaches a control point. It can be expected that the user 8 informs the server 5 of the presence of a temporary control. The server 5 then alerts other users 8 who are approaching the temporary checkpoint within a certain time after this checkpoint has been reported. In the example of FIG. 3, the server 5 is accessible both from an administrator station 11, and from a client station 12, by bidirectional links 13 and 51, respectively. Thus, an administrator can manage the operation of the navigation system 4, for example by scheduling updates of the information contained in the database 6, managing the user registrations 8 to the services of the various service providers 9 available, by entering the database 6 of the common general parameters, etc. Certain information contained in the database 6 can also be directed to the station 10 administrator 11. A user 8, can access from the client station 12 to its specific parameters stored in the database 6 of the server 5. The user 8 may, from the client station 12, for example change his user account by changing its subscriptions to the services of different service providers 9, or personal data recorded about him. The user 8 can also record on his client station 12 information from the database 6 of the server 5. The communication of the positions 11 and 12 with the server 5 is via a web portal 50 forming part of the server 5. The communication between the server 5 and the navigation terminals 1, and 20 between the server 5 and the service providers 9 is typically done via a service portal 14. The service portal 14 is in bidirectional relation with the database 6 Similarly, the web portal 50 is in bidirectional relation with the database 6. Thus, the database 6 of the server 5 is able to store and distribute information relating to both the service providers 9, the users 8, and indicated by at least one administrator. The server 5 is able to calculate an objective to be programmed on a given navigation terminal 1. For this, it takes into account some of the specific parameters corresponding to said navigation terminal 1. The server 5 also takes into account in the calculation of at least one optimum route objective general common parameters. These two types of parameters are also accessible to the hostess, when the user 8 uses this service for the hostess to choose itself a route objective to be programmed in the navigation terminal held by the user. In the embodiment shown in FIG. 6, the server 5 is capable of communicating announcements to the navigation terminal 1. For example, a shop 17 can program in the server 5 the automatic sending of messages. an announcement to any navigation terminal 1 entering a defined geographic perimeter 18. This announcement is for example an invitation to the user 8 to request the server 5 programming its navigation terminal 1 with the purpose of route the shop 17. The invitation is accompanied by a promotional offer that may be related to the news, especially in relation to anniversary dates stored in the database 6 of the server 5. The sending of the advertisement from the server 5 is represented by the arrow 19. The terminal of Navigation 1 (Fig 1) typically comprises a housing 60 open to allow access to the touch screen 2. The dimensions of the housing 60 are, for example, 129.8mm wide, 78mm long, and 14mm thick. The navigation terminal 1 comprises in addition to the loudspeaker 3 for broadcasting sound information, a microphone 20 connected to voice recognition means enabling the user 8 to enter information in the navigation terminal 1 without the need for concentration. particular from his part. The navigation terminal 1 has a socket 21 to be connected to a power supply, for example located inside a vehicle in which the navigation terminal 1 is used. The navigation terminal 1 also includes a port 22 to be connected for example to the client station 12, 25 and a battery, not shown. In addition, the navigation terminal 1 comprises a local memory, not shown, in which map data are stored. The navigation terminal 1 also comprises remote payment means which are not shown in the figures. The user records his banking data among the specific parameters of the navigation terminal, preferably from the client station 12, and it is always the same bank data that is used during a payment. It is possible to register several bank details, and to choose at the time of payment from which bank account the payment is made. Buttons 23 which are used to turn on and off the navigation terminal 1, and to navigate from one menu to another of the software installed on the navigation terminal 1. According to a not shown embodiment of the navigation terminal 5 1, it is perfectly smooth, including in particular no button outside the button to turn on and off the navigation terminal 1, or significant difference in level between the portion of the housing 60 surrounding the touch screen 2 and the touch screen 2. FIGS. 4 and 5 illustrate examples of graphic interfaces 24 that can be displayed on the touch screen 2. FIG. 4 is a view of the graphical interface 24 when the navigation terminal 1 is rolling out information guidance to the programmed route objective from the server 5. Various boxes 25 at the bottom of the touch screen 2, are reserved for displaying guidance information. This information is, for example, the estimated time of arrival, the speed of the navigation terminal 1, the direction to be taken at the next intersection represented by an arrow 27, the name of the route objective corresponding to the guidance in progress, etc. Other pictograms are viewable on the touch screen 2 and some correspond to a location on the touch screen 2 20 which provides access to another menu. Thus, the pictogram 28 provides access to a sound adjustment menu, the pictogram 103 provides access to a main menu, the pictogram 31 provides access to a menu corresponding to a particular service provider, and the pictogram 36 provides direct access to the service of contact 25 with a hostess. The pictogram 110 allows the user 8 to inform the server 5 of the presence of a speed control. The speed control may be localized by means of the information provided by the user 8, or without direct location information provided by the user 8, but by virtue of geolocation data of the navigation terminal 1 transmitting the information signal of the user. presence of a speed control. The pictogram 29 simply enlarges the display on the portion 32 of the touch screen 2 on which is represented the portion of the road map on which the navigation terminal 1 is located by the geolocation means.

Pictograms 37 each represent a particular service provider as well as the setting of the internal parameters of the navigation terminal 1, and access to the modification of the specific parameters. Arrows 38 make it possible to scroll through different pages comprising pictograms 37. Area 39 is provided for displaying a title, for example Main Menu. Adjusting the internal settings includes adjusting the brightness of the touch screen 2, adjusting the sound volume, choosing colors, and so on.

Of course, the invention is not limited to the examples which have just been described and many adjustments can be made to these examples without departing from the scope of the invention. In particular, other service providers than those mentioned can be made available to a navigation terminal user, other criteria, categories, than those mentioned can be taken into account in the navigation system. In addition, other services can be implemented on the navigation terminal, such as for example a means for measuring the blood alcohol content of a driver associated with a means of contacting a taxi company proposed in case of measurement greater than the authorized standard. It is also possible that the same navigation terminal can correspond to several user parameters. In this case, the navigation terminal is identified at startup by the server, then the user is in turn identified by the server, for example through a pseudonym entered or selected in a list from the navigation terminal. The identification of the user then makes it possible to attribute to the identified navigation terminal personal data relating only to the user. In the case where navigation terminals are rented by an agency, a representative of the agency may have access via a client station to the specific parameters relating to each navigation terminal, to erase personal information after using a terminal 5 navigation by a customer.
