Description

Method for creating browsable document for a client device}

The present invention relates to mobile servers and client devices and data that is transferred between them and browseable at the client device. In particular, the present invention relates to a method for creating a browseable document having a personalized and / or context dependent look for a client device.

Electronic documents of a computer system can be viewed by using a browser (of a client device) that retrieves a document from a server and displays it on a display. The electronic documents currently being browsed are the so-called web pages created for the purpose of web browsers. Web pages are often designed by using known markup languages and pages are often related to graphics, links, and other creative styles. Web applications and web services can generate many kinds of content based on requests from client devices.

Traditionally, web page content, or electronic documents, is stored on a server located in a computer system that is somewhat stationary and can have a fixed (wired) connection to the network. The server serves the document of the markup language to the browser of the client device, which can understand the markup language and display the document accurately on the display of the client device. The content to be shown may not necessarily be plain text, but it may provide interactive elements, such as buttons and hyperlinks. The basic idea of Web technology is to provide data that is shared between multiple client devices, either publicly or privately. The client device requesting the content may be a wired or wireless computer system, but may also be a mobile device. In local networks, such as a company's network, a fixed server is usually shared among employees. Therefore, data, such as a calendar, is serviced to authenticated users of client devices connected to the server, and such users can edit the serviced data.

As said, the traditional server is fixed, but the publication US 2003/0076792 A1 also introduces the possibility of using mobile devices as servers. Such a server is referred to in the specification as a mobile server. Other aspects are already known in mobile servers that are web servers. However, it can be appreciated that a mobile server may be needed for both owners of mobile servers and users of client devices. Therefore, the present invention is not based on existing problems and relates to the needs of the foregoing.

The present invention is for Internet usage and possibilities anticipated in the context of a personal device, such as a mobile terminal operating as a host for a web server. It is known that methods for personalizing (customizing) the look of the personal device by lids or by designed user interfaces are currently used for personalization. The present invention extends personalization by giving an opportunity to share a personal look even on client devices. In other words, the present invention relates to defining skins for mobile web applications based on other kinds of data, such as configuration or contextual data, on a personal device.

The present invention provides a method for enabling personalization of mobile homepages as well as other mobile content that can be shared via a web interface. In addition, the present invention aims to provide a customized look to the content of a personal device so that features and usability are maintained.

It is therefore an object of the present invention to provide a method for creating a browsable document, the method comprising the steps of determining context data relating to a personal device, defining information relating to a style relating to the context data, and content and style Parsing the browseable document according to information about.

Another object of the present invention is to provide a configuration database comprising means for determining context data relating to a device and means for defining information relating to a style relating to the context data.

It is yet another object of the present invention to provide a device for determining context data relating to a device, defining information about a style relating to the context data, and sending a browseable document along with content and style information to a client device. It is.

Another object of the present invention is to determine context data relating to a personal device, when stored in a readable medium and executed on a computer, to define information about a style relating to the context data, and by means of information about the content and style It is to provide a computer program product comprising code means suitable for parsing a browseable document.

The present invention is to service and possibly generate a configuration style (eg, cascading style sheet (CSS)) at the mobile server based on other kinds of context data available to the server at the time of servicing the request. The personal device may provide rules for controlling the kind of context data used in that situation. By using the configuration style, it is possible to copy the look and feel of the personal device's user interface to a website provided on the client device. Context awareness makes aspects of the invention wider.

The present invention has a wide range of advantages for mobile technology. First of all, personalization of browseable content in relation to phone applications is facilitated by the automation of technical details, which facilitates the content owner's effort to share data or even to design and record the layout of a document. One of the most important benefits of the present invention is the "skin" for such web applications, where the owner only provides data and context (the default "homepage" application with which contacts, messages, logs, blogs, etc. are combined) and does not provide the application itself. "(That is, appearance) is possible. It is possible for an owner to write a private page, but even for a home page using such a style infrastructure, only a small percentage will know the know-how and even have less time and attention to actually do it. Hence owners of personal devices can configure their own dynamic styles to be used in web pages and stored on the personal device server. The styles are also stored on a server outside of personal devices, allowing the owner to use newer style versions and improvements.

Basically, thanks to the present invention, it is possible for personal information of a personal device to be provided to other computing devices. The present invention more tightly binds the relationship between these two computer systems because the content of the personal device can be shared with other computers in a similar look, which also improves the usability of the content.

The present invention is described by the examples provided by the accompanying drawings and the following description. These examples are provided for the purpose of understanding only and therefore no unnecessary limitations should be derived from them.

In the present invention, web browsable content is provided from a personal device to a client device. Personal devices herein refer to mobile devices such as mobile phones, smart phones, communicators, PDA devices. The client device may also be a mobile device or a wired or wireless personal computer. Browsers play an important role in client devices. The browser can create content from the mobile server and display it correctly on the display. While web browsable content is naturally related to web pages hosted by a mobile server, such as a home page, the present invention relates to personal device applications such as, for example, calendars, contacts, messages, logs via a web interface. Makes it possible to access In addition, a mobile web server (“mobile server”) can serve as a host of mobile / weblogs and galleries. Web browsable content may be formed by using known markup languages such as HTML or XHTML. The content is provided with a style scheme during the process of the present invention, which style scheme may be formed by known cascading style sheets (CSS). CSS is a language for describing the presentation of electronic documents in markup language. CSS is used to define, for example, color, font, layout, and other style features for document presentation. The term "context data" in this specification refers to, for example, settings of a personal device or other data used to determine what configuration style to use for the required content. "Configuration data" refers to layout settings or style data that determines how browseable content is made visible. The idea of the present invention is to create the required content to look similar to the content of the personal device. This means that the user interface features of the personal device will in time generate in the browser's content according to the personal device's settings.

One example of a system according to the invention is shown in a simplified manner in FIG. 1. In this example, the personal device, such as mobile terminal 100, comprises a mobile server. When the client device 150 requests a web page or other content data from the mobile terminal 100, the mobile server provides the requested data via the network 125 with the style customized to the client device 150. The individualized style is determined by the setting at the mobile terminal 100. Another example is shown in FIG. 2. The difference to FIG. 1 is the external server 130 for providing style to the content of the personal device. Therefore, after receiving the request from the client device 150, the mobile terminal 100 determines its settings and requests the corresponding style from the external server 130. Two examples of how a style document is obtained for a client device are described. The first example is to insert a style scheme into the returned browseable document so that the browser gets both the content and style of the same document at once. This means that the style configuration comes from the device 100 and there is no additional roundtrip to retrieve the style document. This example relates to FIG. 1. In another example, a style construct can be externally linked to a browseable document that references it. In this example, the browser may need an extra roundtrip to get the style rules that define the page to handle itself. Now, this external style configuration (“outside” in terms of browseable documents) can still come from device 100 (see FIG. 1), or it can come from another server 130 (see FIG. 2).

The system may also include, for example, a configuration database stored in the personal device 100. The configuration database is configured to define rules regarding what kind of context data is considered and what the result is. In the case of a mobile server, the context data may be, for example:

URL pages being requested as part of the request (eg main page, web application with private data, moblog, family photos)

An identifier of the user agent, eg browser software as part of the request

-The identity of the Internet user as part of the request if authentication is possible for the page

The current profile of the personal device (e.g., general, meeting, silent, etc.)

-Current theme set on the personal device (background image, color palette of the GUI, icons used)

Sensory data when the device is communicating with the sensors. The sensory data may be GPS location, atmospheric pressure, number of Bluetooth devices nearby, cellular signal strength, battery status, cell ID, thermometer, hygrometer, accelerometer, device owner's designated mood.

It will be appreciated that the context data can be almost anything and therefore the previous listing should only be regarded as suggestive. The basic steps for the present invention are to request content from the personal device and to determine what settings, i.e. context data, are on the personal device. According to the setting, the style for the layout of the content is retrieved from the configuration database. The style is used to render the page you want to view on the client device. When the browser receives a web page, it will begin parsing it, and will know which style should be applied and which style can be downloaded from any given URL. Based on connecting to the corresponding server, either a mobile server or a fixed server, a given style can be retrieved from storage. A fixed server can be a so-called 'style web server', which provides styles for different users. The style that is retrieved does not necessarily exist on the server when the page is requested. Styles can be created dynamically on demand. If a style is created in a hurry, it is basically a web application that serves a document of style data rather than the ordinary pages formed by the markup language. One example of such a case is a style generator web application that, when running on a personal device, can take the current theme on the device and generate a corresponding style among them. The new created style can be saved for later use or can be permanently removed. After the browser obtains the content and composition style, the browser renders the page and makes it visible to the user.

An example of signaling for the present invention and in connection with FIG. 1 is shown in FIG. 3. In this example, the web browser user "user2" 350 and the mobile server owner "user1.mobile.org" 300 belong to the same family. User1 has configured terminal 300 in such a way that family members can view core applications (eg, calendars) on the terminal 300. In this example, user2 requests access to the calendar from the mobile server 300 (a). The mobile server 300 requests authentication from the browser 350 (b), and after receiving it (c), the mobile server 300 determines the current setting and theme of the mobile terminal (d). Themes define styles for applications. In this example, the theme is called "romance." User 2's web browser 350 notifies to use the style found at the address /css.cgi?cdi=romance (ie, a URL referring to the same web server as the mobile server) (e). When the browser 350 requests the corresponding style document (f), the style is served from the generated or stored style database (g, h). After receiving both the style and the calendar, the browser can render and display page 355.

4 illustrates an example in which the web browser user 450 is anonymously accessing a publicly available page on the mobile terminal 400. "User1", the owner of the terminal 400, configured a style configuration on the second web server 430. The second web server 430 includes a style generator arranged to provide a style service that can be executed by, for example, operators. This service allows people to configure parts of their style on the second web server 430 so that the style can only be retrieved by calling the generator. In this example, user1 is configured so that the public style "pub" must be the "default" theme. Therefore, when the web browser 450 requests the gallery anonymously (a), the mobile server 400 determines the current setting (b) and with the style identification "pub" and the style owner "user1" to the style server. Return link (c) The web browser 450 then requests the corresponding style from the second web server 430, which is a style server, in which the style corresponds to the identification information " pub " What is this is checked (e). After determining that user1's style "pub" relates to the default style, the second server 430 returns the style to the web browser 450 which can render and display page 455 (f). .

In one example, a user may specify that all pages served from a personal device should be dressed up as a basic look, except for pages of core web applications (calendar, contacts, etc.) given to family members. For family members, pages should be in a personal look. In another example, a user may configure pages to generate a web page look-for example, tropical-sunny, Nordic-rain-and calendar dates, such as Christmas, Easter, or even seasons, with more dynamic consideration of GPS location and atmospheric pressure. Can be.

As a further example, the context data may be the result of queries to third party servers. For example, if a personal device has a GPS antenna but no atmospheric pressure, the personal device can access the weather forecast web service and query the current weather around the current GPS coordinates, and if so configured by the user You can map it with that style.

When serving a web page, the mobile server consults a configuration database to devise the styles that are included in the page. Style commands are not necessarily inserted into the web page stream, but since a style can be referenced by its identifier, the browser will make subsequent requests for the style to render the page.

Some examples of screenshots from both the display of the personal device and the display of the client device are shown in FIGS. 5-7. It can be seen from FIG. 5 that the content of display 500 of the personal device may appear the same style configuration and the same content on display 550 of the client device. Icons 505 and 555 and colors used in web page 550 correspond to the current theme of the personal device. The example in FIG. 6 is similar to that of FIG. 5. But in this example, different viewers take a different style. The content of personal device 600 will appear to the owner of the mobile server in a similar style that can be seen in the user interface of the device. In the case of the owner, note that the web page resembles the user interface of the device after the owner has logged in. Therefore, the web page of the client device 680 is also provided with a "logout" button 685. Other users who are not logged in are given different layouts for the content of their personal devices. Such browsers 670 may have default colors and icons, but may have a "login" button 675.

An example of comparing calendars is shown in FIG. 7. In this example, user1 wants to have a meeting with user2. User1 uses his / her computer to browse user2's mobile website and access user2's calendar. user1's mobile website and calendar are pre-opened. User1 can easily distinguish which of the views 780, 770 of the calendar belongs to, because the calendars are given the owner's name and the calendars can have different styles of different colors and icons. This is because both have the theme of the corresponding personal devices 700, 720. User1 has calendar functions (eg, edit / delete 787) and a logout button 785 on the webpage 780 for his / her own calendar. However, access and edit options for user2's calendar are only provided if user1 can log in to user2's calendar.

An example of a personal device is shown in FIG. 8. The device comprises or is connected to communication means 820 having a transmitter 821 and a receiver 822. There may be other communication means 880 having a transmitter 881 and a receiver 882. The first communication means 820 may be adapted for remote communication and the other communication means 880 may be a kind of short range communication means, such as a Bluetooth ™ system, a WLAN system (wireless local area network), or suitable for local use and communicating with other devices. It can be another system that can. The device 800 according to the example of FIG. 8 includes a display 840 for displaying visual information and imaging data. In addition, the device 800 may include interaction (conversation) means, such as a keypad 850 for inputting data. In addition to or instead of the keypad 850, the device may include a stylus whether the display is a touch screen display or not. The device 800 comprises an audio means 860 such as an earphone 861 and a microphone 862 and optionally a codec for encoding (and if necessary decoding) audio information. The device 800 may comprise an imaging means 810. The controller 830 may be integrated into the device 800 to execute functions and execute applications on the device 800. The controller 830 may include one or more processors (CPU, DSP). In addition, the device includes a memory 870 for storing data, applications, and computer program code, for example. Server 890 is used in accordance with the examples described above.

In the above examples, the URL that causes the style configuration to be retrieved may correspond to a personal device or a style server. A style construct can exist when, but not necessarily, a browseable page that references it is sent back to the browser. If a style is created in a hurry, it's basically just a special web application that serves configuration styles, rather than serving regular HTML pages. It can be seen that this is similar to the use of web applications that generate images based on submitted data (eg, maps by street address). In addition to existing styles, it will be appreciated that a style generator running on a personal device can take the current theme of the device and create a corresponding style therefrom.

When style scripts are run locally on a personal device, the amount of arguments to the scripts is small, such as http://user1.mobile.org/css.cgi? cid = curtheme. On the other hand, if the style script is run on another server and various context data (GPS location in this example) is taken into account when generating the style, the amount of arguments will be greater, for example http://style.operator.com/css .cgi? mid = user1 & themeid = romance & gps = 25E_60N.

In the above examples, CGI is said to be a way of generating CSS streams, but it will be appreciated by those skilled in the art that CGI is provided for understanding purposes only. The possible techniques to use can vary and, for example, Perl, Python and PHP can be used to program the script generation. It is also possible to have "mycssgenerator" in C / C ++. In addition, Java-based technologies can be substituted. By understanding the great variety of scripting languages, those skilled in the art will also understand that the present invention is not limited to any of those and can be implemented by some other technique.

It will be apparent that modifications and variations of the examples of the described embodiments are possible without departing from the protection scope of the invention as set forth in the claims.
