Description

IMPROVED USER INTERFACE

Field of the Invention

The present invention relates to a method for rendering location dependent information on a communication terminal. The invention further re- lates to a communication terminal, a computer program product, and a system for rendering location dependent information.

Background Art

The present invention is generally within the field of personal naviga- tion. One of the basic user scenarios in this field is the 'Find nearest¹ problem: What are the close by restaurants? What are the nearest gasoline stations or cinemas? Which people are around?

Also in the field of navigation is the closely related "Orient myself problem: Where am I? How far am I from the nearest subway station? How long will it take me to get there?

The "Find nearest" and "Orient myself problems primarily occurs when a user enters unknown turf, during business or leisure traveling, when exploring parts of a city not visited frequently by the user, etc. As the working life as well as the private life are getting even more mobile and outgoing, the need for fast, easy-to-use and portable solutions to "Find nearest" and "Orient myself problems are getting even more relevant.

Before the era of the Internet and mobile communication, the most common solutions to "Find nearest" and "Orient myself problems were road- maps, street signs, guide books such as Lonely Planet, and asking strangers for directions. These solutions were limited in the sense that the achieved information were often outdated or inadequate and it would often take the person quite some time to find what he or she was looking for. Furthermore, these solutions seriously lacked a coolness factor, as the user would have to stand around with a clumsy map and try to orient herself, which often lead to the user making a fast (and thus un-informed) choice to avoid too much public embarrassment.

With the advent of the Internet, content service providers such as Yahoo and Map24 started offering on-line applications allowing the user to key in his or her position along with a specification of what he or she was looking for. In more advanced versions, the application would then provide a list of the nearest options and potentially a route description of how to get there shown on a map. Such solutions suggested more options to the user and worked faster than the pre-lnternet solutions mentioned above. However, as these web based solutions were not portable, the user would still be left with only a paper map when on the go. Recently, personal orientation solutions such as those provided by Yahoo, Map24 and the like, has been embedded in mobile phone technology to overcome the lack of portability. One example of such a solution is the Way- finder software based on the Nokia S60 platform. Here, the user can enter his or her position via textual input (e.g. street name, street number, city, country) and subsequently choose what to look for or specify a destination, and information about the destination and route suggestions are provided to the user.

The S60 technology does provide a portable solution to "Find nearest" and "Orient myself problems, but there is room for improvement. With the current solution, the user has to provide several pieces of textual input before he finds what he is looking for. Also, the user will often have to iterate the input several times to seek out different options. Furthermore, it can be difficult for the user to see the information presented on the display, as the application originally was adapted for the significantly larger display connected to a personal computer. Thus, the current solution does not provide a fast, easy and cool solution to the "Find nearest" and "Orient myself problems.

Summary of the Invention

An object of the present invention is to wholly or partly overcome the above disadvantages and drawbacks of the prior art. More specifically it is an object to provide a method for rendering location dependent information on a communications terminal, said method comprising the steps of retrieving a position of said communications terminal, presenting said position in said spatial orientation metaphor, retrieving a predetermined set of categories comprising objects with location dependent information, determining criteria for said objects to be retrieved, retrieving said determined objects associated with said set of categories, retrieving location dependent information associated with a first object of said determined objects, presenting said first object in said spatial orientation metaphor.

This method provides a fast and cool way of rendering location de- pendent information via a communications terminal. It can be adapted to a portable communications terminal such as a mobile phone, and will thus enable a user to get info on his position relative to an object such as a restau- rant belonging to a category as for example Chinese restaurants, "Chinese" then being the criteria for retrieval. By going through these steps and afterwards presenting a first object automatically on a spatial orientation metaphor, the user will get the desired location dependent information in a fast and cool way, a service which the current art does not provide.

Preferably, said method further comprises retrieving location dependent information associated with the remainder of said objects and presenting said remainder of said objects in said spatial orientation metaphor.

By also retrieving and presenting location dependent information about the remaining objects, it is possible to present a range of objects for the user to browse and choose between. For example, the retrieved and presented object could be all restaurant in a given proximity of the communications terminal and thus the user.

In a preferred embodiment, said method further comprising refining the number of said presented objects involving determining one or more preferred object from said objects by browsing the presented objects, exchanging information related to said one or more preferred objects with one or more external sources of information, and setting parameters for said spatial orientation metaphor. The advantage of refining the presented objects is that is en- ables the user to faster get to the desired piece of location dependent information.

Advantageously, the method's retrieving of said position involves retrieving said position from a GPS (Global Positioning System) network, retrieving said position by ground antenna network triangulation, retrieving said position from an input given by a user, or retrieving a remote position different from that of the position of said communications terminal.

The advantage of retrieving said position from a GPS network and by ground antenna triangulation is that a well-established and well-functioning technology is applied and that no user input is required. An advantage of re- trieving said position from an input given by a user is that the dependence on an external network is eliminated and that it is possible to retrieve a position different from the actual position of the communications terminal.

Preferably, the spatial orientation metaphor of said method comprises a map over a proximity of said retrieved position. The advantage of a map is that it is a well-known and easy-to-use media for location dependent information for most users. Advantageously, the predetermined set of categories of said method are any of a system-defined set of categories, a user-defined set of categories, a set of categories according to previous user input, a set of categories comprising most frequent visits in the past. By using a system proposed set of categories, the amount of required user input is decreased, speeding up the rendering of location dependent information. A set of categories according to previous user input and a set of categories according to the most frequently visited brings along the advantage that the user's preferred categories are proposed automatically. In a preferred embodiment, the method's criteria for determining objects to be retrieved are the objects belong to the same category, the objects are within a certain proximity of said retrieved position, the objects' popularity; or any combinations thereof. The advantages of these criteria are that they enable a fast and easy browsing of the retrieved objects. In a preferred embodiment, the method's retrieval of objects associated with said set of categories involves determining association with metadata of said objects, searching through a content database stored in said communication terminal, and searching through an external content database. The advantage of searching through a content database database stored in said communications terminal is that the information is always at hand regardless of the connection to an external network, whereas the advantage of searching through an external content database is that it decrease the need for local storage space on the communications terminal and allows easier update of the content. ' Preferably, the method's presenting of the retrieved object in said spatial orientation metaphor is carried out by displaying an icon with appearance in accordance with metadata associated with said retrieved objects. The advantage of an icon is that is enables a small but easily recognized identifier suited for example the screen of a mobile phone. Advantageously, the method presents the details of an object automatically in said spatial orientation metaphor after a predetermined idle time, by indicating selection of an object by pressing a key when a pointer is aligned with said object, by indicating selection by pressing a key associated with an object or any combinations thereof. By automatically presenting the details after an idle time, the details can be presented conveniently without further user input. The advantage of presenting the details by pressing a key, for example with a pointer is aligned with an object, is that the user has full control of what is presented when. Furthermore, by combining the idle time and the key pressing, the details can be presented with input, but speeded up by a user overruling the automatic presentation by pressing a key.

In a preferred embodiment, the method further comprises a step of de- termining a route to said retrieved objects. The advantage of this is that the user fast and efficiently can be presented with the desired location dependent information, for example the closest Chinese restaurant, as well as information on how to get there.

Preferably, the method presents a route to said retrieved objects. The advantage of this is that the user fast and efficiently is presented with the desired location dependent information, for example the closest Chinese restaurant, as well as information on how to get there.

Advantageously, the objects presented in said spatial orientation metaphor in the method can be browsed by physically interacting with a user interface presenting said spatial orientation metaphor. The advantage of this is that it enables a user to quickly look through the retrieved objects and potentially choose a favorite.

In a preferred embodiment, the method presents details of an object in said spatial orientation metaphor when a distance between said position and said object is within a predetermined value range. This makes it possible to focus the user's attention to nearby objects.

Preferably, the method's refining of retrieved objects is performed by receiving a textual user input, matching of a pattern in a search field with objects available for selection, or any combinations thereof. Advantageously, the matching of the refining step involves receiving a first sequence of symbols from said search field, identifying a corresponding sequence of symbols in at least a first candidate item from a group of items, presenting a first candidate item comprising a corresponding sequence of symbols, and receiving a user input for selection of a candidate item. The ad- vantage of this is that the user can easily control the refining by typically 2-5 keypad inputs, thus making for a fast and versatile refinement of the retrieved objects.

In a preferred embodiment, the method's presentation of objects matching text input is updated between each user input. The advantage of this is that it enables the user to quickly and efficiently refine to the point where a favorite object is apparent. Preferably, the method's browsing of presented objects comprises toggling between objects, redrawing said spatial orientation metaphor in a case where a selected object is outside a display area, displaying object details upon a user input of pressing a key, displaying object details upon a user in- put of aligning a cursor with an object icon, displaying object details automatically if retrieved position and an object is within a predetermined distance, displaying object details automatically if only one object is present, displaying additional information of an object via an options menu or a soft key, or toggling between groups of objects according to predetermined range, time or number of objects. The advantage of the above mentioned is that they offer various ways of toggling between object details depending on the outcome of the refinement of the retrieved objects.

Advantageously, the method's step of exchanging information involves exchanging information with a recipient associated with a selected object, or exchanging information with web pages of destinations. The advantage of this is that it enables the user to retrieve more information than that immediately available. Also, it enables the user to contribute to the information associated with an object by for example submitting a review of the object to an external source of data, such as a webpage comprising restaurant reviews. In a preferred embodiment, the method further comprises any of the following user configurable parameters: appearance of the presentation, behavior of the presentation, idle time before automatically retrieving or presenting detailed information, selection of categories, threshold range of distance between said position and a position of an object for automatic selection of said object, zoom level, or any combinations thereof. The advantage of these user configurable parameters are that they enable a user to adapt the method to most possible application areas.

Preferably, the method's retrieval of objects is carried out via any of the access technologies GPRS, Bluetooth, WLAN, SMS, MMS, e-mail, e2e mes- saging, client server protocols, or any combinations thereof. The advantage of any of these is that it adapts the method to existing system readily available and known to most users.

A further object of the present invention is to provide a communications terminal for rendering location dependent information, said terminal compris- ing a GPS for retrieving a position of said communications terminal, a processor for retrieving a predetermined set of categories comprising objects with location dependent information, determining criteria for said objects to be re- trieved, retrieving said objects and location dependent information associated with these objects, and a user interface for presenting a spatial metaphor and one or more objects in said spatial metaphor. This communication terminal enables a satisfactory implementation of the method for rendering location dependent information of the present invention.

Preferably, the communications terminal comprises a mobile phone, a cellular phone, a smart terminal, a personal digital assistant (PDA) or any combination thereof.

A further object of the present invention is to provide a computer pro- gram product, such as a computer-readable medium having computer- executable components, for rendering location dependent information, said computer program product being adapted to retrieve a position of said communications terminal, present said position in a spatial orientation metaphor, retrieve a predetermined set of categories comprising objects with location dependent information, determine criteria for said objects to be retrieved, retrieve said determined objects associated with said set of categories, retrieve location dependent information associated with a first object of said determined objects, present said first object in said spatial orientation metaphor.

Preferably, the computer program product is further adapted to retrieve location dependent information associated with the remainder of said objects, and present said remainder of said objects in said spatial orientation metaphor.

Advantageously, the computer program product's refining of the number of said presented objects involves determining one or more preferred ob- jects from said objects by browsing the presented objects, exchanging information related to said one or more preferred objects with one or more external sources of information, setting parameters for said spatial orientation metaphor.

A further object of the present invention is to provide a system compris- ing a server, a communication network, and a communications terminal, wherein said server and said communications terminal are communicating via said communications network, and wherein said server is adapted to provide said communications terminal with a predetermined set of categories comprising objects with location dependent information, determining criteria for said objects to be retrieved, retrieving said determined objects associated with said set of categories, and retrieving location dependent information associated with a first object of said determined objects. Preferably, the system's server provides an application for rendering location dependent information which is executed on said communications terminal.

Advantageously, the system's application is browser based.

Description of Preferred Embodiments Figure 1 illustrates schematically a communication terminal 101 in which the present invention is implemented. The terminal 101 is capable of communication via an air interface 103 with a radio communication network 105 such as the well known systems CDMA2000, D-AMPS, GSM, UMTS, EDGE, etc. The terminal comprises a processor 107, memory 109 as well as input/output units in the form of a microphone 111 , a speaker 113, a display 115 and a keyboard 117. Radio communication is realized by radio circuitry 119 and an antenna 121. Connected to the radio communication network 105 is a controller 123. The details regarding how these units communicate are known to the person skilled in the art and is therefore not discussed further. The terminal 101 is further capable of communication via the air interface 103 with a global positioning system (GPS) 130 for determining its current position.

Figure 2 shows a flowchart for a method for rendering location dependent information on a mobile communications terminal. In a first step 201 of the depicted method, the current position of the mobile communications terminal is determined. The determination of the current position can be done by connecting to a satellite network such as the GPS, but it can also be done by triangulation from a mobile phone network such as a GSM network (step 6) or by any other means for position determination. In a second step 202 of the method, the determined position is presented to the user in a spatial orientation metaphor. This spatial orientation metaphor can for example be a map or an air photo. In a third step 203 of the method, a set of categories is retrieved, the categories being for instance restaurants, cinemas, cultural attractions, community services, grocery stores, hotels, other communication terminals or the like. With a category comprising other people's communication terminals a user can be enabled to determine the position of people he knows. The set of categories can have a default setting, but can also be pre- determined by the user. The categories can also be adapted to historic choices of the user. Once the set of categories have been retrieved and one or more categories of choice have been specified, objects are retrieved in a fourth step 204 from the category in accordance with the position determined in the first step 201. The objects can be retrieved from a local storage such as an MMC-card but it can also be retrieved from a remote server. The information retrieved comprising information of the objects can also comprise details of the distance from the determined position to the various objects. The information on the various object may in addition be updated continuously in accordance with changes in the position of the mobile communications termi- nal. In a fifth step 205, the information retrieved on the various objects from the selected category can presented on a two-dimensional (2D) or a three- dimensional (3D) map on the screen of the communications terminal, but it can also be presented on an air photo in 2D or 3D, also on the screen. The number of objects displayed should depend on the determined zoom level of the spatial orientation metaphor, so that a low zoom level will allow a large number of objects to be displayed and a high zoom level will display less objects.

After the presentation of the retrieved location dependent information, the user have the option to refine presented information in a sixth step 206. This can be to refine a search for restaurants to only include Chinese restaurants or to only include restaurants starting with the letter "C" or the like. Furthermore, the user can browse the retrieved objects by retrieving further details about the various objects. These details can origin from an external database, from a homepage on the world wide web associated with the object in question or any other external source of further details. Also, the external source can be route planners, yellow pages or the like. In figure 3 is shown an example of refining the location dependent information by means of search box 320 for user input present on top of a presented 2D map 321 with the retrieved information such as the position of the terminal 317, the nearest object 319, and a selected object 318. The user in- put can be in pattern comprising letters, numbers or words. In the example in figure 3, the user has via a keypad 322 entered the word "Chinese", whereby the information presented on the 2D map 321 is refined to only include Chinese restaurants 318. The refining by textual input can be adapted to refine further and further as more and text is entered, so for example the textual in- put "chi" would refine a restaurant search to only include Chinese restaurants, Chili restaurants or restaurants with a name containing the text string "chi", whereas expanding the input to "Chinese" would refine the search to only include Chinese restaurants. Once the location dependent information has been refined to a desired level, the user can in an additional step browse through the results by means of a user input interface (e.g. a joystick or a keypad) of the communications terminal to find a preferred object. The browsing can include toggling between pop-up windows containing further details about the refined objects, but it can also be browsing according to historic popularity or another favorisation criteria. Upon selection of one of the objects, a route from the current position of the communications terminal to the selected object can be presented on the screen of the communication terminal. As illustrated in figure 4, this can be in the form of a line 327 to follow on a 2d map 321 , it can be a list of directions 328 to which streets to follows or a combination thereof. It can also be audio instructions given to the user about when to turn left or right etc. Furthermore, the map can contain concentric circles (323 and 324) illustrating different distances such as 500 meters or 1000 meters from the position 317 to the objects (318 and 319 and the like). Such circles can enable the user to quickly know how far it is from his current position to the object presented on the map. Instead of concentric circles showing the absolute distance, different walking distances can be illustrated on the map 321 as circle-like lines (325 and 326) as shown in Fig. 4b. This functionality is especially interesting in a case where a user has pre-selected historic or cultural locations of interest and, for instance during a tour of a city automatically is presented detailed information of sights when passing by sufficiently close to the sights of interest. The user may also select a specific category, or specific items from one or more categories and then be presented a route connecting these items such as to create an individual tour. Conveniently, the user can follow the path on the map presented by the terminal, and as the user is approaching a point of interest, such as a church, a fountain, plaza, or the like, detailed information automatically comes up on the screen. In case the user is particu- larly interested in the object, further sources of information may be provided such as Internet links, books or souvenirs related to the sight. The detailed information may be a description of the sight, opening hours, contact information, etc. A sight can be a historic building, shop, public restroom, etc. interactive guide.
