DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the present invention relate to an electronic reader and a method for implementing an electronic reader software on a computing device.

Referring now to figure 1, there is shown a schematic block diagram 100 of a distributed architecture that is used to implement an electronic reader software in accordance with an embodiment. The architecture comprises a server unit 102 which can store one or more source files. The files can include legislation files 104. The source file can be text files, such as government Acts which are organised in pages.

Server 102 is also used to store a number of databases, such as indexing databases 106, which are used to index source files 104; a database of user profiles 108 and annotation databases 110. Server 102 is connected to a communication network 112 through a communication interface. Data can be exchanged between server 102 and remote computing devices such as desktop or laptop computers (114) and/or portable computing/communication devices (116).

Figure 1 also shows a schematic 118 with the main components of each remote computing device connected to server 102 through network 112. Each computing device comprises a 'hard memory' 120 and a 'soft memory' 122. The hard memory has a first portion used to store a number of service files, which are extracted and parsed from the source files 104, and an indexing database, which uses cross-link files 124 to source files 104. The computing devices have a user reading interface comprising a reading area 128 which displays a portion of text contained in files 124 loaded in memory 122.

Referring now to figure 2, there is shown a further schematic block diagram 200 which presents additional details of the architecture and memory management. Figure 2, in particular, shows the organisation of the internal memory 202 of a mobile computing device, such as a tablet, running the electronic reader application software.

The mobile application provides a user with a list of available files, for example government Act files, stored on the server. The files are available to be downloaded onto the hard memory 120 of the mobile device.

The relevant source file is derived from a HTML file containing the body of text and headings. The HTML file is passed through a parser to generate a series of custom XML files (202a and 202b) and a SQLite database (106a and 106b) for each source file.

Opening a source file, for example, an ACT file loads an associated SQLite database indexing file, for example 106a for source file 104a, which is copied onto the soft memory 122 of the mobile device. The indexing file specifies which XML file to read from the hard memory 120 of the mobile device.

Reading area 128 allows for continuous real time infinite scrolling by using three text pages. Before any scrolling, the first text page is disposed above the visible bounds of the display area, the second text page is disposed across the display area and the third text page is disposed after the display area. The headings for these three text pages are copied into the soft memory (DRAM) 122 of the device. The page viewed by the user is passed through the rendering module 204 and displayed on the reading area 128 of the device.

In this embodiment, there are always three pages stored in the soft memory 122 of the device. This is shown by the three pages 206 loaded in memory 122 in figure 2. The height of each page depends on the vertical scroll buffer multiple (i.e. the text kept in the buffer is equal to the height of the view multiplied by an amount). A continuous scrolling functionality 208 is provided adjacent to the reading area. The scrolling functionality 208 is designed to account for the length of the main source file.

In figure 2, this is shown as pages 6, 7 and 8. For example, as the user scrolls down the display reading area then page 7 will be discarded from the soft memory of the mobile device and page 9 will be loaded into the soft memory of the mobile device. In this example, the following actions are performed by the mobile computing device : the page data is copied from the hard memory to the soft memory; if the data source does not return any text, then a blank page is shown; the last buffered heading and last buffered line are recorded; the text that appears before the current offset (i.e. before the first line of visible text) is fetched; the pages that appear before the first visible line are built; text is drawn onto the display area to a text page. Text is fetched in paragraph groups. Details of the drawing methods are provided in a section below.

Referring now to figure 3, there is shown a flow diagram 300 which lists the main method steps for implementing the electronic reader software on a computing device in accordance with an embodiment.

At step 302, the service files are downloaded from the remote server and stored in a first hard memory portion of the computing device. At step 304, the index database is downloaded from the remote server and stored in a second hard memory portion of the computing device. At step 306, set of the service files is selectively loaded from the first hard memory portion to a dynamic memory portion based on indexing information in the database. Further, at step 308, a user reading interface comprising a reading area is provided on a display of the computing device. Content from a portion of the set of service files loaded in the dynamic memory is then displayed on the reading area at step 310. The service files are loaded in the dynamic memory portion selectively so that the content from a portion of the set of service files can be rendered on the reading area in real time and enable continuous scrolling through the content of the source file on the reading area.

In order to implement continuous scrolling, a customised scrolling functionality is provided on the reading area. Traditional reading software provide scroll bars which show the position of the text in respect to the rendered section of a page. In the reader described herein, only part of the original source file is rendered at any particular time, therefore a traditional scroll bar would not be in the appropriate position relative to the entire source file.

In the reader described herein, the scrolling functionality estimates the rendered lengths of each page comprising the source file in order to estimate the total length of the entire source file. The relative position of the scroll position indicator is based on the position of the current page in terms of the entire source file. This functionality is implemented by a dedicated scrolling routine which will be described in more detail in a section below.

In some embodiments, a source file may comprise a dictionary section. This is often the case for legislation files, such as government Acts. Selecting a term defined in the dictionary section of a source file, where available, queries the indexing database on the soft memory 122 of the mobile device. This will instruct which XML file contains the definition on the hard memory of the mobile device. The header containing this definition is loaded from the XML file into the soft memory of the computer device and is rendered and displayed on the mobile device. If the selected word is tagged as dictionary word in the database, a definition from database on the remote server is fetched and displayed in a popup window. If definition is not available or the user is not connected to the database, an error message is displayed.

In some embodiments, the electronic reader software described can be implemented in a computing device such as a desktop or laptop computer through a web browser.

Figure 4 shows a flow diagram 400 which lists the main method steps for implementing the electronic reader software through a web browser in accordance with the embodiments .

The original text files are further processed and converted into corresponding HTML files. The HTML files are then segmented and stored into a database on a remote server, step 402. A database comprising an index of service files is downloaded from the remote server and the database is stored in a hard memory portion of the computing device, step 404. Subsequently, a set of service files is selectively downloaded from the remote server to a memory portion based on indexing information in the database, step 406. A user reading interface that comprises a reading area is provided through the web browser on a display of the computing device, step 408. Finally, segments of the HTML files loaded onto the soft memory are rendered and displayed on the reading area, step 410. The step of selectively downloading the set of service files 406 is performed in a manner such that the content from a portion of the set of service files can be rendered on the reading area in real time and enable continuous scrolling through the content of the source file on the reading area of the browser.

As users scroll to the end of the rendered content the next segment of HTML content is loaded from the database on the remote server onto the soft memory of the computing device and rendered. The earlier HTML content loaded is cleared from the soft memory of the computer device.

Referring now to figure 5, a flow diagram 500 which lists the main steps performed by the electronic reader software while a user is scrolling content rendered onto the reading area. At step 502 a set of service files is selectively loaded from hard memory to dynamic memory and display on the reading area. At step 504 a user scrolling action through the text displayed is detected. A series of tests are performed at step 506: if it is the first time rendering the document render from the top of the document; if approaching either the top or bottom of the rendered content, then fetch headings from the data source on the remote server and copy to the soft memory of the computing device; if approaching the bottom of rendered content, render more items at the bottom of the viewpoint; if approaching the top of the rendered content render more items at the top of the viewpoint; if user is scrolling down then check if excessive content is loaded at the top of the document; remove content related to excess sections at the top of the document from the soft memory of the computing device; if user is scrolling up then check if excessive content is loaded at the bottom of the document, remove content related to the excess sections at the bottom of the document from the soft memory of the computing device.

If the scrolling requires, a further service file is loaded from the first hard memory to the dynamic memory and the last or first service file is discarded, step 508.

In the embodiments where the source file comprises a dictionary section, for example government Acts, selecting a term defined in the dictionary section of a source file, where available, will query the database on the remote server for the relevant heading containing the definition. The header containing this definition is loaded into the soft memory of the computing device and is rendered and displayed on the web browser.

The source files comprise a number of headings that divide the source files in sections. The indexing database comprises index references to headings in the source file.

When content is displayed from the set of service files on the reading area, the software uses a first offset value representing a distance, calculated as number of lines of text displayable on the reading area, between a heading in the source file and the text rendered on the display area.

In addition, a second offset value representing a distance calculated as number of lines of text displayable on the reading area between the beginning of a paragraph in the source file and the text rendered on the display area is used to display the correct content on the reading area while the user continuously scrolls through the different pages of the source file.

Embodiments of the reader software, provide users with the capability to store annotations through a web browser or mobile device on source files viewed. Figure 6 shows flow diagrams (600, 650) which lists the main steps performed by the electronic reader software to store and manage annotations. Annotations are managed in a separate SQLite database which is hosted on the remote sever. The position of the annotation is based on the index for that view and a character offset for the starting and ending section to which the annotation relates.

In the web browser, annotations are stored directly on a database on the remote server in a user profile (see user profiles databases 108 and annotations databases 110 in figure 1).

In the mobile device application, the annotations are stored on the hard memory of the mobile device. The annotations are synchronised with the database containing the user profile on the remote server every ten seconds if the device has network connectivity. Otherwise the device can sync with the remote server when the device is next connected to a network.

Deriving the source files

Source files can be derived from HTML files containing the body of text and headings. HTML files are parsed to generate a series of custom XML files and a SQLite database. The procedure follows these steps: read source file; run primary parser to identify elements; utilise child parser specific to element identified; child parser to collect information and add to the relevant XML file for that child parser; primary parser to add to relevant XML file for the primary parser; SQLite database to create an index of headings derived from the outputted XML files.

In the embodiments where the source file comprises a dictionary section, for example government Acts, the definitions are stored as headings in the index of headings and marked as 'definitions' through use of a dictionary child parser.

The custom XML files and SQLite are bundled into a compressed into an 'ACT file' which is available on the remote server.

Method to draw text

This method is used to draw text in the reading area and comprises the following steps: store the page start or page end location; restart the page so that a new set of information can be drawn; measure text during drawing to check if the page is filled (this is done by calculating the starting offset based on (1) whether content is being drawn top to bottom or bottom to top; and (2) whether the first paragraph group has been partially rendered on the last page); call procedure to fetch and draw the content of the page (i.e. to render the text and any styling such as borders based on the paragraph group type, e.g. a table); store the current position in the document; hide the portion (if any) of the first paragraph group that has already been rendered by the last page (e.g. for paragraphs that span two pages); return the height of the last rendered paragraph group that has already been displayed (i.e. the portion of the last rendered paragraph group that was included in the page).

Scrolling routine for scrolling functionality

This method is used to implement the scrolling functionality and comprises the following steps: calculate scroll speed based on offset for current scroll view against previous scroll view; update state to show that the user has started scrolling; update context.

Referring now to figures 7 to 11, there are shown screenshots of an electronic reader software running on a tablet device in accordance with embodiments.

Figure 7 shows a user login screen where a user can be identified and linked to respective user profiles and annotations information stored in the remote server.

Figure 8 shows a document download screen where a user can select a source text file, in this case a government Act for downloading.

Figure 9 shows a reading view in the table application with the real time continuous scrolling functionality on the right side of the screen.

Finally, figure 10 and figure 11 respectively show a regular reading view with a bookmark function, for bookmarking portions of text of the source file in use, and the split screen functionality of the application, for viewing two separate section of the source file simultaneously.

Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed before the priority date of each claim of this application.
