| Crisis Management and Command and Control or more generally distributed (tactical) real-time decision support -- decision makers and gatherers of information |
| Forums and Chattering on the Web -- the world! |
| Distance Education -- teachers and students (and administrators) |
| (Tele)medicine -- Doctors (primary and specialist referrals), Nurses, Patients and administrators |
| Business Enterprise (strategic) Support as in Lotus Notes -- Employees of Business including especially managers |
| Multidisciplinary Applications including Collaborative design -- teams of up to 10,000 engineers |
| Computational Steering -- one or more computational scientist and visualization device |
| In each case Collaboration involves support for dynamic interactive shared distributed objects and one needs both synchronous (as in Tango/Habanero) and asynchronous (basic Web/Lotus Notes/Email) support |
| The shared objects are both client and server side |

| There are several natural applications as Tango supports the "Bridge" concept of Warner and Balch which effectively claims that dynamic collaboration ("Interventional Informatics") approach (as supported by Tango) 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.
|
Note analogies between C2 and medical planning and decision support with several different experts and people with different skills in the field

| Tango 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/Maryland) Tango could be used in team health care which involves both spontaneous collaboration and the asynchronous case represented by later expert consultants.

| 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
|
| Distributed Modeling and Simulation (from DMSO) with "humans and computers in the loop" already has this type of architecture |
| NCSA has developed a prototype collaborative visualization system using Tango (2D and 3D images can be shared by participants with viewpoint and choice of rendering replicated) |

| Wearable computers (with components such as battery, disks, CPU) wore on a belt with a handheld monitor (640 by 480 today) allow us to bring a computational grid to the warfighter |
| There would be a wireless link using low speed digital cellular connection |
| There is enough memory and disk to run a browser and Tango client on the remote unit |
| This links implementers in field together and to central decision support |
The 1997 wearable computer technology is shown in next two foils but perhaps most intriguing are devices like the JavaRing where 14,000 distributed at JavaOne conference

| This combines TANGO for collaboration with web and distributed object based computing and database systems on the server side |
Whatever the computation one can link to it by exporting the results to CORBA or the Web and using this interface to get synchronous or asynchronous collaboration
|
| NPAC is demonstrating a prototype of this type of system using WebFlow |
| On client one can share tools such as CAD systems like CATIA or AUTOCAD so Tango interfaces with API to these system and drives "slaves" from state extracted from linkage to master. |

| Computing Systems like NPAC's WebFlow control flow of information between linked objects. For example, in dataflow model, user must supply routines to process input of data that drives a given module and output of data for other modules |
TANGO supports shared objects and user supplies routines that read or write either
|
| In each case one needs an API to object which can either be proprietary (as in AUTOCAD or ArcoInfo GIS) or generic as in CORBA or Web Middle tier linkage |

"Object Web" "backend" Learning Resource (as in NPAC WebWisdom)
|
Synchronous collaboration tools (such as TangoInteractive) allow participants (students, teachers) to sample and discuss interactively the SAME asynchronous resource used for self based learning -- either as augmentation to lectures or for full asynchronous learning

|
| Jackson State major HBC University with many computer science graduates |
Do not compete with base courses but offer addon courses with "leading edge" material (Web Technology) which give JSU graduates skills that are important in their career
|
Needs guaranteed 30 (audio) to 100 (video) kilobits per second bandwidth assuming course material mirrored at JSU
|
| This illustrates that synchronous delivery is a "guided tour" of large asynchronous resource -- 250 megabytes in total |
| Important to have curricula mentor and technology expert at remote site |

Internetics is the study of technologies, services and applications enabling and enabled by the world wide Internet
|
| Will prototype and test education technologies, infrastructure and demonstrate the feasibility of new approaches to education using International Collaboration |
