Reading in Scalar
The types of content in a Scalar book and how they work together.
Finding your way in ScalarAt the top-left of the Scalar header, you'll find a series of icons. Rolling over the compass icon reveals a number of options for readers to orient themselves in the current book, including recently viewed items and a set of global visualizations.
Recent Items. Recently viewed pages in the current Scalar book items are stored in the "Recent" menu in reverse chronological order.
Global Visualizations. Unlike visualizations for individual pages, visualizations accessed via the Scalar header display content and connections for an entire book, based on critera set by the reader. Readers can choose the "Format" for the visualization, that is, how the connections between content is visualized (choices include: Grid, Tree, Radial and Force-directed); the type of content to be visualized (choices include: All content, Table of contents, All pages, All paths, All tags, All annotations, All media, All comments, or Current page); and the type of connections or relationships to be visualized (choices include: All relationships, Parents and children or No relationships).
Index. Rolling over the menu icon in the Scalar header will reveal the Index icon, located just below the main table of contents. The index contains a hyperlinked catalog of all content in the current book. The content is divided up, for the reader's convenience, into tabbed categories (Paths, Pages, Media, Tags, Annotations and Comments).
While text itself needs no introduction, its appearance in Scalar bears mentioning a few items of note:Media Links. Each media link is preceded by an icon for the type of media it references; clicking a link to a time-based media file causes it to start (and subsequently to stop) playing.
Notes links. These links are preceded by a note icon and serve a similar function as footnotes, displaying additional content when clicked.
Embedded media files have a few extra features that go beyond simple playback and viewing. The Details button in the lower left corner of the media opens an expanded view in which all aspects of the media file, from annotations to metadata, can be examined. Clicking "Permalink" will take you to the media's dedicated page, and clicking "Popout" will open the media file itself in a new window.
If a media file has annotations, they will be available in different ways depending on the media type and display method. In some cases, an "Annotations" link will toggle the display of all of the file's annotations, which can be individually clicked; in others, you'll need to click the "Details" link to access them. For text and time-based media, pop-up "live annotations" will be displayed when the media is cued up to an annotated region.
Paths are sequences of pages--like chapters in a book, but more flexible. You'll know you're about to embark on a path when you see a "Begin this path" button at the bottom of a page, with a table of contents beneath. Clicking the button (or on any of the listed pages) will take you into the path. Once you're on a path, additional navigation at the top and bottom of the page identifies the name of the path you're on, how far you've traveled, and provides links to move stepwise along the path. Sometimes paths lead to other paths; other times they lead back to the "Home" page of the book.
If you want to get a better sense of the structure of all of the paths in a book, try the Path Visualization.
Tags are markers that are applied to pages that have something in common. If the page you're looking at has been tagged, you'll see a "Tagged by" at the bottom of the page, followed by the name of the tag (or tags) which act as links to other pieces of content that share the same tag (or tags).
If you want to see how tags in a book are interrelated, try the Tag Visualization.
Any reader is free to submit a comment on any page or media file in a Scalar book by clicking the "Comment on" link at the bottom of the content, whether or not they have a Scalar account. It's even possible to add a comment to another comment in threaded fashion. New comments, however, will not be visible within the book until approved to go live by an author user for the book.
New Ways to Navigate
Scalar 2.0: What's New
Scalar books are often comprised of complex structures. Scalar 2 was designed to help readers better orient themselves within these structures, including upgraded navigation systems accessed via the new Scalar header.
New Header Navigation
The header incorporates an interactive table of contents allowing users to explore a book without ever leaving the current page. At the top-left of the header bar, you'll find a series of navigation icons. Rolling over the menu icon reveals the book's table of contents, which, as in the old interface, acts as a kind of main menu for the book (and, just as in Scalar 1, authors are free to add whatever content they wish to this menu). Clicking on the title of a page within the table of contents will navigate the reader to that page. Additionally, clicking on the arrow just to the right of a page title will reveal the information tab for that page. If a page in the menu is also a path, tag, comment, or annotation, its information tab will also show its related items, which can themselves be similarly explored. In this way, the table of contents gives readers an interactive, global view of a book's structure.
New Visualization OptionsThe new interface also comes equipped with a more nuanced and customizable set of global visualizations. Easily accessible via the new header, readers now need only roll over the compass icon and then choose their desired visualization format. Once there, readers can limit, or otherwise define, which sets of objects and relationships within the Scalar book as a whole they’d like to see and in what graphical format. More specifically, readers can choose the "Format" for the visualization, that is, how the connections between content are visualized (choices include: Grid, Tree, Radial and Force-directed); the type of content to be visualized (choices include: All content, Table of contents, All pages, All paths, All tags, All annotations, All media, All comments, or Current page); and the type of connections to be visualized (choices include: All relationships, Parents and children or No relationships).
A More Robust IndexFinally, the new interface includes an expanded index. Users will find the index icon at the bottom of the table of contents accessed from the menu icon in the header. The new index contains a hyperlinked catalog of all content in the current book, divided for the reader's convenience into tabbed categories (Paths, Pages, Media, Tags, Annotations and Comments).
