Enabling human users to interact via their computers, the Tango Interactive collaboratory exploits Web resources and interoperability. Through the Internet, this multiuser system helps individuals collaborating in real-time from remote locations to share Web- and non-Web applications. A simple API supports rapid porting of existing applications into Tango's collaborative framework, which supports both synchronous and asynchronous interactions with team members and shared datasets. Tango is a powerful collaboratory system tapping the full potential of the applet download capability provided by Java. Built using the event-sharing paradigm, the system supports coordinated but independent views of related information. We will describe applications including distance education and crisis management and go through examples of linking various web resources with Tango. In particular we will discuss collaboratizing standard web pages with forms, database access and shared simulations built using either C or Javabeans.

Background: 100% Elementary

No assumptions made about knowledge of collaboration technology. Familiarity with web browsers assumed. Discussions of Tango API are not a major part of tutorial but require understanding of web-linked databases and Javabeans for a few foils each.

Participants with PC laptops and ethernet connection can follow tutorial interactively using Tango on their machine. We will bring server and hub.

We will improve the material given in http://www.npac.syr.edu/users/gcf/alliance98/, which is divided into four major areas. Firstly we will review approaches to collaboration including synchronous (Tango, Habanero) and asynchronous (such as Lotus Notes) methods. Then we will discuss the Tango system architecture and show how to download and install it for participants with machines. We then review current and possible applications including education, command and control/crisis management, collaborative visualization and computing. We will give lessons from our experience in using Tango in distance education as presented in http://www.npac.syr.edu/users/trscavo/jsufall97/. Finally we will present the Tango API where especially compared to cited URL, we will add more worked examples. We will discuss with the participants any applications they would like to make collaborative covering both appropriate approach and how to implement under Tango. We will give the tutorial using Tango itself on a few linked laptops we will bring which can be linked to any other machines participants or conference make available. This is in addition to standard projections of material from one of machines in Tango session.

The presentation is suitable for either those intending to use Tango -- say in distance education -- or those interested in building collaborative environments.

Fox is an expert in the use of parallel architectures and the development of concurrent algorithms. He leads a major project to develop prototype high performance Java and Fortran compilers and their runtime support. NPAC has pioneered use of CORBA and Java for both collaboration and distributed computing. Fox is a proponent for the development of computational science and its follow on "Internetics" as an academic discipline and a scientific method. He has established at Syracuse University both graduate and undergraduate programs in these areas. All courses have been made available on the Web and his research includes HPCC technology to support education at both K-12 and University level. His research on parallel computing has focused on development and use of this technology to solve large-scale computational problems -- such as numerical relativity and earthquake prediction. Fox directs InfoMall, which is focused on accelerating the introduction of high speed communications and parallel computing into New York State industry and developing the corresponding software and systems industry. A recent set of activities center on Web collaboration technology and its application to synchronous distance education
