Javanti
Javanti is an integrated development environment for interactive presentations and
eLearning applications (CBT and WBT).
Virtual slides and smart elements
In Javanti the author works with virtual slides to create content. On each slide one can
put smart elements. Those components can be of various complexity, starting with simple
text, there are also audio, video, simulation or experiment settings available. Each
element has specific properties, e.g. color, size or position. All properties can be
manipulated at edittime and animated at runtime. There are already many elements
available for Javanti: text labels, formated text, buttons, input fields, images
(rotateable, scaleable and transparency), animated gifs, powerfull freehand graphic
features (vector-based), predefined shapes (arrows, cubes, signs), bézier curves,
multiple-choice tests, fill-in-the-blank tests, drag & drop tests, assignment and
arrangement tests.
Timeline
Slides are arranged in a timeline to enable both defining a course/presentation
structure and to set keyframe animation. The horizontal arrangement defines the slide
sequence and the view duration for each slide. You can use multiple slide layers to show
more than one slide at a time. This allows you to combine slides for content, chapter
information and background skins (like a master slide).
Scripting language
Elements take respect to user interaction. Actions can be defined for input events such
as mouse clicks or movements. Using these actions an individual behaviour for each
element can be defined. It is very simple to change or animate properties of other
elements on a slide. A complete scripting language Tcl (Tool Command Language) is also
available to program more sophisticated features. Tcl is extended with some powerfull
multimedia commands not only to create stunning effects but to improve the visualization
of dynamic processes.
Shared Property Groups
It is possible to use a set of properties by more than one element. That is a number of
elements use the same properties. Whenever a property changes, this change will be
applied to all elements that are using its property group. This is very usefull to share
always the same color, position, size or image source for a set of elements. For example
you can change the color for a group of menu buttons in one step. Or you can ensure that
headline elements in different slides are always at the same position and of the same
size, font and color.
Extensibility
Using an open plugin concept Javanti is very easy to extend. A simple interface makes it
very easy to develop new components or to integrate existing Java applications into
Javanti. There are also interfaces to develop new property groups, property types and
manipulation tools. To install new components the user only has to copy files into the
plugin directory.
File format
The file format of Javanti is based on XML (eXtensible Markup Language). Using transform
languages such as XSLT it is very easy to translate a Javanti file into other XML-based
formats and vice versa.
Platform Independence
Javanti is 100% pure Java. Thus, Javanti is running on all major platforms including
Windows, Linux, MacOS X and all systems for which a Java Virtual Machine (JVM) is
available.
