Abstract:
Devices exist that can access and retrieve data from the Internet. These devices use a web-browser of some form to achieve this end. To retrieve a-rid render web-pages using a web-protocol, such as, for example, HTTP or WAP, requires a relatively sophisticated client device. Such a client device requires large amounts of memory and a relatively powerful processor to run the web-browser to access data sources such as, for example, the Internet directly. However, often users are only interested in specific, small volume, data such as a current share or stock price, exchange rate or temperature, for example. Hence, using such a relatively sophisticated device as described above to achieve a relative simple aim is unsuitable. Therefore, embodiments provide a data communication system comprising data specification means for a user to specify at least one data item and preferably a number of items of data, data capture means for capturing specified at least an item of specified data from data sources and a data display device for downloading, wirelessly, at least one item of data from the data capture means, wherein the data display device is incorporated in a personal article.

Description:
FIELD OF THE INVENTION  
       [0001]     The present invention concerns a communication system and method and, more particularly, to such a system and method for specifying distributed information sources, obtaining data from those sources and communicating that data by wireless communication to a mobile display device.  
       BACKGROUND TO THE INVENTION  
       [0002]     There are known devices that enable a user, whilst mobile, to obtain data from data sources. For example, WO 00/50963 discloses a wearable device that wirelessly receives financial information for output to the wearer of the device. The main function of the device is as a watch and the display of financial information is an additional function. However, the device is dedicated to communication with one particular data source.  
         [0003]     Devices are known which facilitate wireless access to the Internet and multiple data sources such as, for example, WAP mobile telephones. However, in common with personal computers these tend to use web browsing software which, before a user can access a web site, must be loaded and directed using appropriate URLs or by selecting a pre-stored address. An example of such a device is disclosed in WO 01/82027 A2.  
         [0004]     In the case of frequently accessed sites, and many users access a selected number of sites frequently, this can be burdensome, particularly if it is only a single selected item of data, such as a share price, sports score, train time etc, from the site in which the user is interested. WO 01/71557 A2 discloses a system that attempts to reduce the traffic-carrying requirement of such a system by transmitting only the data of interest. However, the system requires a relatively sophisticated client application to be executing at the receiving device, which positions the received data correctly within a previously rendered HTML page. The processing and memory requirements to support such a client application are unsuitable for thin client applications.  
         [0005]     It is an object of embodiments of the present invention at least to mitigate some of the problems of the prior art.  
       SUMMARY OF INVENTION  
       [0006]     Accordingly, a first aspect of embodiments of the present invention provides a data communication system comprising data specification means for a user to specify a number of items of data, data capture means for capturing the specified items of data from data sources and a data display device for downloading at least one of the captured items of data by wireless communication from the data capture means, wherein the data display device is incorporated in a watch.  
         [0007]     Advantageously, embodiments of the present invention may enable a user to gain mobile access to multiple data sources without the need for excessive time, effort and complexity and without requiring a relatively thick client application to be executed at the client device.  
         [0008]     A second aspect of embodiments of the present invention provides a data communication system comprising data specification means to allow specification of a number of data items, data capture means to capture the specified data items from data sources and a data display device to download the specified items of data by wireless communication from the data capture means, wherein the display device is incorporated in a personal article, which personal article has an additional function.  
         [0009]     The phrase “a personal article” as used in this specification comprises or means any article a user may carry, wear or have about their person.  
         [0010]     The additional function may be any function that an article personal to the user may perform, which is additional to the article&#39;s function as a data display device and which is a non-wireless communication related function. The additional function may be the main function of the personal article. For example, the additional function may be as a watch, key ring, a pen or other writing instrument, jewellery or other adornment, a pen knife or tool(s), torch, a bag, a purse or wallet, spectacles, a game or plaything, a camera, or an item of clothing or footwear.  
         [0011]     Embodiments of the present invention enable a user, in possession of the personal article incorporating a data display device, to access a plurality of data sources and, specifically, data items selected from those data sources. Moreover, the data display device is not dedicated to those particular sources. Instead data sources can be specified by the user. In effect, specification of the data sources by the user with a separate device, data specification means or selector, and capturing the specified data at a further device, data capture means, that is, a data captor or capturer, enables a browsing or equivalent-type software function to be dispensed with at the data display device. Moreover, the “form” of the data display device, that is, its incorporation into a personal article means that access to data sources does not necessitate an additional article. Thus, the time, effort and complexity involved in gaining access to the specified data items is reduced as compared, for example, to using a PDA or WAP enabled device.  
         [0012]     The data display device may comprise means for requesting the download of items of data. The data display device preferably comprises processing circuitry and the requesting means is linked to processing circuitry which, in response to operation of the requesting means, generates a request wirelessly communicated to the data capture means for downloading data from the data capture means. The requesting means may comprise means for selecting a specific item of data for downloading. The selecting means may support repeated downloading of an item of data. The selecting means may be operable to select an item of data for downloading repeatedly at specified time intervals or when the item changes. The selecting means may be operable to adopt any one of a number of states, the number corresponding to the number of data items specified. The selecting means may also further comprise indicia so as to enable a user to identify which state corresponds to which data item.  
         [0013]     Embodiments of the data display device further comprise communications means enabling wireless communications between the data display device and the data capture means. The data display device also further comprises a display for displaying downloaded items of data. Preferably, the data display device comprises audible alert means for announcing the completion of downloading. Still further, the data display device preferably comprises a memory for retaining downloaded data items, for example, in readiness for display or for comparison with at least one other previously downloaded data item.  
         [0014]     The requesting means may be a switch arrangement or other actuator arrangement capable of initiating a request for downloading. The selecting means may comprise a separate switch for each state or a switch actuable between each of the states. For example, in the case of a data display device for downloading a predetermined number of data items, such as, for example, eight data items, there may be a switch for each item or a switch actuable between any of the predetermined number of states or positions. Each switch or switch state may be indicated or coded using, for example, a corresponding colour or may have a respective icon, possibly downloaded to the data display device, or other indicia to allow the user to associate the states or positions and the data items. A switch or switches may be arranged, for example, such that a single actuation requests a single download, two actuations requests repetitive downloads and three actuations requests a download only if the data item changes.  
         [0015]     In a preferred embodiment, the data display device is incorporated into a watch with a rotatable bezel around the rim of the watch serving as a selection means or selection mechanism, the bezel being rotatable to each of the predetermined number of positions or states. It will be appreciated that if the data display device is incorporated in other items, other existing elements or features of those items may be adapted to serve as selection means or mechanism or to present a number of positions or states. For instance, the actuation or clutch mechanism of a pen or pencil could serve as the selection means or mechanism.  
         [0016]     The data capture means may comprise means responsive to requests for downloads from the data display device or to internally generated prompts to capture data.  
         [0017]     The responsive means may capture data once or repeatedly. Captured data items may be evaluated so as to enable pre-selected actions, such as the updating of the data display device, to be performed. The data capture means may capture data items by extracting them from data sources. The data sources may be sites on the Internet or other data network, with the data items being pieces of information of a web page. The data capture means is further preferably adapted for access by the data specification means for specifying the data items.  
         [0018]     The data capture means could be in the form of a computer server. The server may have an IP address so as to be accessible in the manner of a web site using a personal computer, laptop computer, a mobile telephone, WAP enabled device or any other Internet enabled device. The server may present web page type content for a user to specify the data items, which may be password or otherwise securely protected and may enable a user to modify the specification for data capture.  
         [0019]     The data specification means may comprise any device capable of accessing the data capture means. For example, when the data capture means comprises a server computer, the data specification means may be a personal computer, laptop computer, a mobile telephone, WAP enabled devices or any other Internet enabled device. The data specification means may be provided with software to support access to the data capture means. The software may also facilitate configuration of the data display device. The data specification means and data capture means may communicate with one another as part of a configuration process for the device either directly or via a network.  
         [0020]     A further aspect of embodiments of the present invention provide a computer program element comprising computer program code means to implement a system, device or personal article as described in this specification. Further embodiments provide a computer program product comprising computer readable storage or a computer readable storage medium having stored therein or thereon such a computer program element. The term computer program and computer program element refer to either a complete, that is, self-contained, program, or to part of a program, such as, for example, a library routine, a subroutine, a module or the like.  
         [0021]     A still further aspect of embodiments of the present invention provides a data communication method comprising the steps of specifying a number of items of data using data specification means, capturing the specified items from data sources at the data capture means and downloading the items of data by wireless communication from the data capture means to a data display device, wherein the data display device is incorporated in a personal article, which article has an additional function.  
         [0022]     Embodiments of the present invention further provide a data display device to download data items retrieved from a number of data sources without the use of browsing or equivalent-type software or function at the device, wherein the data display device is incorporated in an article personal to the user, which article has an additional function.  
         [0023]     Preferably, embodiments provide a personal article comprising an input device, a display capable of displaying, in a first portion, data presenting an icon, the first portion being selectable using the input device, a transceiver comprising means, responsive to actuation of the input device to select the first portion, to request and receive data corresponding to the selected first portion and a display driver to display the received data in a second portion of display; the received data having been, prior to the request, previously selected, as being of interest, from at least one data source and, preferably, from a number of data sources.  
         [0024]     The embodiments preferably comprise a personal article in which the input device comprises at least one of an actuable button or switch and a moveable member. In some embodiments, the moveable member might comprise a rotatable bezel for selecting at least the first portion of the display.  
         [0025]     Embodiments of a personal article comprise a watch, key ring, pen, jewellery, or other adornment, a cutting implement or tool, a bag, a purse, a wallet, spectacles, a game or plaything, a camera or an item of clothing or footwear.  
         [0026]     Preferred embodiments provide a watch comprising means to provide at least one chronographic function, an input device, a display, having a plurality of display regions and a data display portion, each region being capable of displaying a respective icon, a transceiver, responsive to actuation of the input device to select one of the plurality of display regions, to request and receive data corresponding to the selected region and a display driver to display the received data in the data display portion of the display.  
         [0027]     Preferably, embodiments provide a watch in which the display regions form at least part of an annulus, the data display portion being is disposed within said at least partial annulus and in which the input device comprises a rotatable bezel disposed radially outward of said at least partial annulus; the bezel being rotatable to select one of the plurality of display regions. Embodiments are provided in which the bezel is rotatable to select the nearest region of the plurality of display regions.  
         [0028]     The movement of the bezel may instantaneously cause a request for data to be sent as soon as the bezel assumes a predetermined position relative to a display region. However, this will increase the traffic and, hence, the power consumption requirements of the watch. Suitably, embodiments provide a watch comprising means to monitor the duration for which the bezel is adjacent to one of the plurality of display regions and in which the means to request and receive is arranged to request and receive the data according to the duration. Preferably, the duration should exceed a predetermined period of time.  
         [0029]     Embodiments provide a watch further comprising a memory for storing at least one of icon data, representing an icon to be displayed in at least one of the plurality of display regions, and corresponding data to be displayed in the data display portion of the display. Preferably, embodiments provide a watch further comprising means to receive and store the icon data in the memory.  
         [0030]     It is probable that the memory capacity of the watch is limited as compared with more sophisticated devices such as WAP phones. Therefore, the memory of the watch should preferably be managed prudently. Suitably, embodiments provide a watch further comprising means to receive metadata associated with the icon data and to reserve or configure a portion of the memory to store data according to the metadata. The metadata assists in the efficient utilisation of the memory of the watch.  
         [0031]     A further aspect of embodiments of the present invention provides a data communication system comprising a selector to select data to be displayed on a display of a watch; the watch comprising: a memory, means to provide an indication of a current time, an input device, a display having a plurality of display sectors and a data display portion, each sector being capable of displaying a respective icon, a transceiver comprising means, responsive to actuation of the input device to select one of the plurality of sectors, to request and receive previously selected data corresponding to the selected sector and a display driver to display the received data in the data display portion of the display; the data communication system further comprising a configuration means to produce, responsive to the selected data, configuration data to configure the memory of the watch.  
         [0032]     Advantageously, the configuration data supports the efficient use of the memory of the watch.  
         [0033]     Preferably, the configuration data comprises at least one of icon data, representing an icon to be displayed in a sector of the plurality of display sectors, and metadata, associated with the previously selected data, to configure the memory to store the received data corresponding to the previously selected data.  
         [0034]     The data may be selected from a single data source or from a number of data sources.  
         [0035]     Once a user has selected or identified data of interest, a reference for that data should preferably be stored to allow it to be retrieved. Therefore, embodiments provide a data communication system in which the selector collates address data, corresponding the previously selected data, for processing by a data capture means; the data capture means being arranged to obtain a copy of the selected data using the address data. Advantageously, the collated data can be used by an application to retrieve copies of the selected or identified data.  
         [0036]     It would be advantageous for a user to have some means of specifying the data to be retrieved. Suitably, embodiments provide a data communication system comprising a selector to identify data to be displayed on a display of a watch; the watch comprising: a memory, means to provide an indication of a current time, an input device, a display having a plurality of display regions and a data display portion, each region being capable of displaying a respective icon, a transceiver comprising means, responsive to actuation of the input device to select one of the plurality of display portions, to request and receive data corresponding to the selected region, said received data being associated with the identified data, and means to display the received data in the data display portion of the display; the selector collates address data corresponding to the identified data.

The computer  102 , in conjunction with the software  110 , represent a form of realisation of at least part of a data specification means or selector. The software  110  is used to compile address data  112  containing addresses of data items for transmission to, and use by, data capture software  114  executable at the server  104 . The server  104  and the data capture software  114  represent a form of realisation of at least part of a data capture means or data capturer. In preferred embodiments, the address data  112  comprises URLs of web-pages, such as, for example web-pages  116  and  118 , that are accessible by the Internet  120  and respective web-servers  122  and  124 . For the purposes of illustration, the web-pages  116  and  118  are depicted as comprising respective data items  126  and  128  of interest to the user (not shown) stored on respective HDDs  130  and  132 . The address data additionally comprises data identifying the specific location within the web-pages  116  and  118  of the data items  126  and  128  of interest.  
         [0058]     In preferred embodiments, the data item specification software  110 , in addition to collating address data  112  for data items of interest, also allows the time or frequency of retrieval of the data items to be specified, optionally, together with an indication of whether the data should be stored at the server in anticipation of receipt of a download request from the watch, forwarded to the wristwatch in anticipation of receipt of a request to display an item of data or forwarded to the wristwatch together with an indication that the user should be notified of the arrival of the data item or items.  
         [0059]     The computer  102  also supports mobile device configuration software  134  that is used to configure the mobile device  108  to receive and display the data items  126  and  128  of interest. The configuration software  134  allows the user to select an icon to be associated with each data item  126  and  128 . The icon will be displayed on the display of the mobile device to support selection of the data items for display. Preferably, the configuration software produces configuration data  136  comprising icon data  138 , representing an icon or a number of icons, and metadata  140  that describes the data to be displayed or associated with the icon or icons.  
         [0060]     The mobile device  108  may be configured using the configuration data  136  via any suitable form of communication channel. For example, the mobile device  108  may communicate with the computer  102  and receive the configuration data via a direct link. The direct link may be a direct physical link, such as, for example, USB or a radio link using, for example, Bluetooth, IEEE 802.11b or some other wireless protocol. Alternatively, the configuration data may be forwarded to the server  104  where the data capture software  114  can be arranged to forward the configuration data  136  to the mobile device using the existing radio communication infrastructure.  
         [0061]     The server  104  comprises, as indicated above, data capture software  114  that retrieves, using the address data  112 , and stores a copy  142  of a requested one of the data items  130  and  132 . The request for one of the data items is received from the mobile device  108  via a radio transceiver  144  operating under the control of communication software  146 . The transceiver  144  is arranged to exchange, via a suitable antenna  148 , data with the mobile device  108  wirelessly.

The mobile device  108  comprises a processor  150 , which in preferred embodiments, operates the device as a wristwatch and displays the time on the display  106 . The processor  150  is also operable to support data exchanges, using a radio transceiver  152 , with at least one of the server  104  and the mobile device configuration software  134 . The mobile device  108  comprises a memory  154 . The processor  150  is arranged to configure the memory  154  for storing the icon data  138  and, preferably or optionally, to configure the memory  154  in light of the metadata  140  to ensure that there is sufficient storage  156  available to store the selected data items associated with icon data  138 , that is, the metadata is arranged to ensure that a sufficient number of words are available to store the selected data associated with the icon data. The memory  154  can store, in the described embodiment, up to eight icons and can be configured to store selected data items corresponding to the eight icons. The icons are displayed on the display  106  and can be selected using a corresponding selection mechanism or means  158 . The selection mechanism or means  158  is used to select one of the displayed icons, which, in turn, causes a download request, corresponding to the selected icon, to be sent to the server  104  via the transceiver  152 . The data capture software  114  returns the selected data item, extracted from the stored copies  142  of the data items, corresponding to the selected icon.  
         [0063]     Referring to  FIG. 2 , there is shown a preferred embodiment of a mobile device  108  in the form a wristwatch  200 . The wristwatch  200  comprises a body  202  bearing a liquid crystal display (LCD)  204 . The LCD  204  comprises a central data display portion  206  and a number of peripheral display regions  208 , which, together, perform the primary function of displaying the current time under the control of the processor  150 . The time may be displayed in numerical form using appropriate digits or in an analogue-type form using simulated analogue hands. In preferred embodiments, the LCD comprises eight peripheral display regions. Preferably, the display regions form an annulus, with any given region being shaped as a truncated sector, or part annulus.  
         [0064]     The regions  208  and data display portion  206  are used, as a secondary function, to display the icons and corresponding data items in response to user actuation of one of a number of control buttons  210  to  214 .  FIG. 2  shows two regions  216  and  218  as containing respective icons  220  and  222 . In the illustrated example, the icons represent a current temperature, ° C., and a Sterling-Dollar exchange rate, £/$. A rotatable bezel  224  to select one of the display regions  208 , that is, one of the regions containing an icon such as, for example, one of regions  216  and  218 . A currently selected icon is, in a preferred embodiment, indicated by having an increased display intensity relative to the other icons. In a preferred embodiment, as the bezel is rotated, the display intensity of the currently selected icon is increased relative to the other icons, which all assume the same relatively lower intensity. Rotating the bezel  224  causes the change in intensity to step through the displayed icons, in effect, those regions that do not contain an icon are preferably not selectable. This facilitates speedier selection of a desired item of information. Selecting an icon using the bezel  224  automatically causes a download request, corresponding to the selected icon, to be transmitted to the server  104 , which responds by forwarding the data item corresponding to the selected icon. The received data item is stored within one of the storage locations  156  corresponding to the selected icon and displayed on the central portion  206  of the LCD  204 .  
         [0065]     In preferred embodiments, the change in intensity is ephemeral, that is, it lasts for a predetermined period of time. This is done primarily to save power consumption.  
         [0066]     The watch also comprises the customary bracelet, strap or other means  226  to allow it to be worn by the user.  
         [0067]     It can be appreciated that the wristwatch, in addition to functioning as a watch, that is with time, date, chronograph, alarm etc. also has the additional function of being capable of displaying downloaded data.  
         [0068]     The manner of use of the system is as follows: on purchasing a wristwatch  200 , a user also receives the IP address of the server  104 , an identification code, password and software corresponding to the data item specification software  110  and the mobile device configuration software  134 . Using the software loaded on to the computer  102 , the user gains access to a number of pages hosted by the server  104  that have the following objects: to enable up to eight Internet site web-pages to be identified, and then to further identify the location a specific data item embedded within the web-pages. The user may, for example, specify the address of a meteorological web page as one of the eight addresses, and within that page identify a temperature being reported, say, for a city. Another seven data items may be similarly identified. The user also specifies for each data item, the manner in which the data item should be captured. The capture might occur once in response to a request received from the wristwatch  200 , repeatedly in response to a request received from the wristwatch  200  or repeatedly irrespective of a request having been received from the wristwatch  200 . For example, a temperature reading for the city may be captured from the meteorological web page in response to a request or repeatedly following the request, or simply repeatedly in readiness for a request once specified. Having specified to the server  104  the data items to be retrieved together with the periodicity or frequency of retrieval, the server  104  can retrieve the specified data items at the appropriate time or times.  
         [0069]     In preferred embodiments, on completion of a download, the wristwatch is arranged to produce an audible alert to indicate that the selected data item has been downloaded.  
         [0070]     Having a continuing interest in the temperature, the user may execute a predetermined number, for example, two, of rapid movements of the bezel  224 , to and from the “° C.” icon or region, consequently generating and communicating a request for repeated downloads to the server  104 . In response, the server  104  monitors the data item, capturing it, for example, every hour and automatically downloads any change to the wristwatch  200 . If the user no longer wishes to be updated regularly, the bezel  224  may be placed in a neutral position, consequently generating and communicating “stop monitoring message” that is sent to the server  104 , which causes the data capture software to cease obtaining the data item. Alternatively, or additionally, the monitoring mode of the data capture software may be terminated, for a currently selected icon, using the buttons  210  to  214 .  
         [0071]     In an alternative embodiment the watch may be provided with icons pre-configured. This avoids the need for the user to go through the steps of selecting sites of interest, but obviously does not permit reselection of sites of interest. It is envisaged that, for example, in accordance with this embodiment, when purchasing the watch, the user will select a watch at least partly upon the basis of the sites with which it is configured. Alternatively configuration (and possibly reconfiguration) may take place at the retail outlet for example.  
         [0072]     In a further modification the icons can be printed on a suitable substrate (re-writable if desired) at the time of configuration, thus obviating the need to provide a dedicated region of the watch&#39;s dynamic display for this purpose.  
         [0073]     Other articles, such as key rings, pens or other writing instruments, jewellery or other adornments, pen knives or tools, bags, purses or wallets, spectacles, a game or plaything, or an item of clothing or footwear may not be normally provided with a display and, thus in order to adapt them for use as part of a data communication system, a display has to be provided in the case of a pen, for example, the display may be mounted of the body of the pen so as to be visible when held in normal writing manner. In the case of spectacles, by way of another example, the display could be a partially reflective surface to the lenses on to which information may be projected.  
         [0074]      FIG. 3  shows a number of flowcharts  300  depicting the operation of an embodiment of the present invention. At step  302 , the data item specification software collates address and location data for an item of interest. That address and location data is stored and added to an address data file  112  containing address and location data for previously selected data items, if any, at step  304 . A corresponding icon to be display on the mobile device is selected at step  306 . Data representing the icon at added, at step  308 , to the mobile device configuration data  136  together with metadata describing the nature of the selected data item, such as, for example, the number of words required to store a selected data item. A determination is made, at step  310 , as to whether or not the data item specification process has been completed. If the determination is that the data item specification process has not been completed, control is returned to step  302 . If the determination is that the data item specification process has been completed, the file  112  containing the address and location data is transmitted to the server  104  for use by the data capture software  114  at step  312 .  
         [0075]     The mobile device is configured using the collated configuration data  136  at step  314 . The configuration data  136  is received and acted upon by the mobile device at step  316 . The configuration process involves storing the icon data in memory and ensuring that a sufficient number of words of the memory are associated with each icon data to allow the storage of data corresponding to any requested data.  
         [0076]     The server  104 , at step  318 , receives the address data  112  for the specified data items and forwards that address data  112  to the data capture software  114 .  
         [0077]     The mobile device  108  detects an input representing a request for a data item from the user at step  320 . A download request is generated and sent to the server  104  at step  322 . The server  104  receives the download request at step  324 . The data capture software  114 , at step  326 , retrieves, preferably, in real-time, the selected data item using the address and location data  112 . At step  328 , the retrieved data item is transmitted to the mobile device  108 . The mobile device  108  receives the retrieved data item at step  330  and displays the received data item at step  332 .  
         [0078]     Although the above embodiments have been described with reference to the real-time download of data items from the web-pages  126  and  132  in response to download requests received from the wristwatch, embodiments are not limited to such an arrangement. For example, embodiments can be realised in which the data capture means retrieves the data items in advance and caches those items until requested by the user of the wristwatch. Alternatively, or additionally, the retrieved data items might be retrieved and forwarded to the memory of the wristwatch  200  in anticipation of user selection at some time in the future. Whether the data is downloaded in real-time or not will depend to a certain extent upon the time sensitivity or importance of the data.  
         [0079]     Although the above embodiments have been described with reference to a download request being sent automatically to the server  104  upon selection of a region, embodiments are not limited to such an arrangement. Embodiments can be realised in which the automatic download request is not sent until one, or a combination, of the buttons  210  to  214  has been actuated. Alternatively, the download request may not be generated and sent until an icon or region has been selected for a predetermined period of time. In both embodiments, the amount of traffic generated by the selection process will be reduced as compared to embodiments in which the download requests are generated and sent automatically. This may have the additional advantage that the battery of the wristwatch may last longer since fewer transmissions are made as compared to the automatic generation and transmission of download requests.  
         [0080]     The above embodiments have been described with reference to the intensity of the icons changing as the icons are selected using the bezel. However, embodiments of the present invention are not limited to such an arrangement. Embodiments can be realised in which the bezel comprises a marker that is used to indicate which icon is currently selected. The region or icon selected is that region or icon that is closest to the marker of the bezel  224 . Furthermore, the embodiments of the present invention are not limited to using a bezel as the selection mechanism or means. Embodiments can be realised in which one, or a combination, of the buttons  210  to  214  can be used to select the icon of interest. For example, the first button  210 , when depressed, in conjunction with the third button  214  may cause the currently selected icon to change intensity and each subsequent depression may select the next clockwise icon.  
         [0081]     The above described data specification means is indicated as collating the address data of the selected data items. However, embodiments can be realised in which the data specification means, working with the data capture means, merely specifies the data items of interest and the data capture means collates the address data corresponding to those data items. Also, the data capture means can, in response to the user specifying the timing of the data capture, using the data specification means, be used to collate the timing information rather than that information being collated at the data specification means.  
         [0082]     Furthermore, although the above embodiments have been described such that each display regions is operated to display icons, embodiments can be realised in which selected ones of the display regions are used to display icons, that is, in use, not all regions may be used to display icon data.  
         [0083]     The above embodiments have been described with reference to the use of metadata to configure the memory of the mobile device. However, embodiments can be realised in which the memory of the device is pre-configured to receive data items have a particular size. Such embodiments would remove, or at least reduce, the need for metadata to be specified and transmitted to the mobile device. Furthermore, the collation of the metadata may be undertaken by the data capture means, which can then conveniently communicate that information to the mobile device using the transceiver  144  and communication software  146 .  
         [0084]     Advantageously, the embodiments of the present invention allow article, having a primary function, to assume also a secondary function, which is related to data display.
