Uses linkage of TANGO to JavaScript WebWisdom which supports Persuasion, Powerpoint, HTML and Screendump mixed Presentations with audio (tagged to specific foils) and notes
Full Webwisdom used by Teacher allows access to full curricula and options
Client (Slave) WebWisdom displays pages chosen by teacher (with same audio and notes) and generates automatic HTML index
  • should integrate with HTML editor to allow student annotation
Currently WebWisdom used in non TANGO mode with classic large screen display
TANGO WebWisdom allows one to use same approach to distributed PC's which is surely more attractive (Web font sizes designed for monitors -- not classroom displays)

To allow use on low speed lines (28.8 kbaud modems), distribute CD ROM of material to students
Client WebWisdom will map URL sent from Teacher WebWisdom to link on PC (if exists) and so ONLY control information is sent on Web
Standard low bit rate codecs support audio and video conferencing over phone lines
For asynchronous learning, ship HTML Index with lesson audio to clients and students use offline with TANGO used to support synchronous audio and video conferencing
Will use in China (already succesfully used material Spring 96 Semester between Syracuse and Harbin) and for Syracuse University "Limited Residency" continuing programs where students visit University once to three times per semester (see Computing for the Future Certificates)
  • Corporate Programs where we substitute limited residency at Syracuse by University team visiting site where many students can congregate

There are several natural applications as Tango supports the "Bridge" concept of warner and Balch which effectively claims that Tango like approach is better model for TeleMedicine than classic videoconferencing/distributed sensor data model
As well as rural distance medicine, we can see many opportunities for home health care especially for geriatric applications.
  • In a separate project we have linked low cost sensors through PC serial port and into Java event handlers so that can feed Home medical monitors to servers and client side filters.
  • Similarily Home education could be attractive for broad professional continuing education population

TANGOsim has interesting applications to medical education with "scenario" playing through particular medical test cases such as pathology images which residents in training are asked to diagnose in collaboration with experts discussing cases. Such events are typically observed by many largely passive people.
In another example suggested by Saltz (John Hopkins) Tango could be used in team health care which involves both spontaneous collaboration and the asynchronous case represented by later expert consultants.
  • Here the database support will be very useful for linking the different medical sessions for a given case.

Clearly Java Collaboration Systems are natural implementations of general environments that mix computers and people
Computational Steering -- a simulation is like a participant in a Tango session which has
  • simulation engine
  • visualization subsystem
  • one of more computaional scientists
Need to link to Tango, Java data analysis/visulaization front ends as well as distributed resource management systems such as ARMS from Cornell

Note synergy with Java Server based distributed computing such as WebFlow which builds an AVS like environment with graphical interfaces to software Integration
More ambitious to upgrade discrete event simulation component of TANGOsim to support full SIMNET/DSI (Distributed Simulation Internet) functionality.
Note that Java is natural language for DSI/Forces Modelling because these typically use object parallelism which fits both language and applet/JavaBean capabilities.
