Differences Between WebSteer and Conventional Applets

The main differences between our approach and the conventional Java applet model created by Sun Microsystems and supported by popular HTML browsers like Netscape Navigator and Microsoft Explorer are:

WebSteer's Applets are Software Components
You don't need to attach applets to HTML pages. This means that you can compose previosly unrelated applets in innovative and unnexpected ways.

The Event Handling System of WebSteer is Easily Scriptable
To create highly interactive assemblies of applets and HTML you need only to write a simple declarative script, like plain HTML, that describes the HTML pages that comprise you courseware, the applets that will be loaded over the Workbench, and how to synchronize the HTML browsing with the applets.

WebSteer's Instruments are Compatible with Applets
To turn common applets into WebSteer's instruments, you need just insert pieces of code that describe how these applets raise events and handle messages. You don't need to recompile the original applet to do this.

Summary of WebSteer's Features

  • the provision of a detached and high-level event synchronization mechanism between applets and HTML browsing.
  • HTML browser specially adapted to reactive environments
  • environment for loading and controlling the execution of arbitrary instructional modules over the Web
  • support to the simultaneous execution of several applets, that may simulate the workings of educational devices
  • possible integration with remotely monitoring systems
  • framework of pre-defined classes that can be used as building blocks for educational software components.
