NII is/will be digital superhighway provided to you by
|
| Current NII is InterNet and World Wide Web but IntraNets are rapidly becoming most important deployment |
| Currently access NII through Internet directly or through an intermediary such as America On-line |
| Currently consumers use a Computer and modem on POTS -- plain old telephone service |
| In future Computers/TV set sets will "converge" and access will be dedicated cable/optical fiber which will be much faster and allow high quality video delivery (ISDN, ADLS or Cable Modem) |
| "Every" Business Office, Every doctor's Office, "Every" school desk, "Every" home (approximately any home on cable) will have such a two-way high speed link to the NII |

Analog as in current Cable Satellite or broadcast TV or radio represents informations by WAVY SHAPES
|
| Digital as in current computers represents everything by NUMBERS and uses "error-correction" so that you receive EXACTLY what is sent with NO distortion of text or images |
So information is more precise
|
| and looks better -- your great art piece is not distorted or the medical picture is transmitted without adding or subtracting tumors/pathologies etc. |

The World Wide Web will develop a marvellous WebTop Environment allowing users to access Web versions of Word Excel(Lotus123) Persuasion(Powerpoint) Databases Lotus Notes etc.
|
| This (as developed) enables a wonderful new software industry as Microsoft no longer has key advantages |
This (as used) enables very effective (business) enterprise systems where "Web" used internally to an enterprise

In future one will NOT write software for either
|
| Rather one will write software for WebWindows defined as the operating environment for World Wide Web |
WebWindows builds on top of Web Servers and Web Client open interfaces as in
|
| Applications written for WebWindows will be portable to all computers running Web Servers or Clients which hide hardware and native O/S specifics |
Full HTML Index
Further WebWindows Software will be modular and allow plug and play insertion of capabilities developed around the Web World -- not a bunch of isolated stovepipe solutions
|
| As an example some of Current Netscape and last year(!) NPAC's WebTools implements UNIX shell/PC file manager capabilities in terms CGI scripts -- allows universal access to these capabilities including powerful Web based (mh) mail |
| NPAC's WebFoil is HotJava/Netscape 1,2,3 Open replacement for Powerpoint/Persuasion |
Particular Application areas (Business, Healthcare, Education) will be built on top of generic NII services so that for instance

| Persuasion and Powerpoint are rather similar monolithic packages which can for instance only be clumsily ported to UNIX as cannot access internal data-structures defining foils |
| WebFoil (NPAC prototype WebWindows presentation package) has |
Extended open HTML source manipulated by powerful PERL5 scripts allowing global changes and linkages of foils from many sources
|
| Backend Oracle database illustrating modular WebWindows approach |
| Using Appropriate templates WebFoil Uses Hotjava or Netscape 1,2 or 3 to display HTML with full Web Power including applets to enable Multimedia and dynamic presentations |

| I expect Java to be the the dominant implementation language for everything on the Web from Servers, Clients, MOO's, filters, Animations, Simulations etc. |
| MOO's are example of customized Collaboratories where on builds Java servers and Clients |
Can build neat clickable images including Visible Human (biology education which won prize in Java Cup) and our 2D "Interactive Journey" clickable Geographical Information System for New York State
|
| Java could perhaps implement translation and other online services |

| JavaScript -- only superficially related to Java and was called LiveScript -- is Netscape's fully interpreted Client side extension of HTML. This is a good integration/customization technology where flexibility more important than performance |
i.e. use JavaScript for Rapid Prototyping
|
Full HTML Index
| There are some cases where JavaScript is a rapid prototyping alternative to Java (Java can in principle do anything!) |
| Current use (demonstrated in WebWisdom) is for customized display's of information where base information, simulations, audio(video), and indices can be linked in a friendly fashion. |
| Syracuse is extending to a set of WebTools (originally developed as Server CGI scripts) with which you can build customized front-ends with user defined configurations choosing between type of access (administrator and naive user would be different) and display capabilities (resolution, color) of terminal |
| Note client side and so fast even though interpreted |
| However does not yet have (but needs) text processing capabilities of Perl |

VRML 1.0 widely available and specifies static 3D scenes through which you can navigate. Already provides universal visualization environment and we have examples of use In Geographical Information Systems
|
VRML 2.0 is just released with prototype browsers but still aspects of technology are under intense research/debate.
|
Full HTML Index
VRML is Very good 3D GIS (Geographical Information System) technology and can be used to generate on the Web, German countryside with other information superimposed
|
VRML is currently and perhaps intrinsically (numbers ascii) inefficient and Java is alternative / augmentation technology
|
VRML 2.0 will allow one to produce collaborative televirtual environments where user is immersed in a computer generated world

| We have Postal Services, electronic mail/newsgroups/listservs which generalize to web linked database supported mail archives with suitable JavaScript framework |
| We have Phone which generalizes to Chat Servers and Forums where "mail" (lines of chat) are in real time but logically equivalent to mail services |
Video Conferencing/Face to Face Meetings map into a set of interactive tools
|
These need digital video, Java Servers and clients etc.

| The Web provides a convenient integration environment for "mature" technologies migrating from existing computer environments. |
| Relational databases are a good example where it is now straightforward in Oracle, DB2, Sybase etc. to provide a Web Interface which can be used for data (mail, curricula material etc.) with Java/JavaScript/Forms based Interfaces |
| Object databases such as Illustra also interfaced to Web |

Store information in databases and NOT Web Pages
|
You can use structured databases such as Oracle to store resource data such as Glossaries in an organized fashion
|
| Can also store unstructured information as illustrated by Usenet computer and other relevant newsgroups |
| Use the powerful Search engines with domain (i.e. particular courses) specific keywords . These can be attached to commercial (e.,g. altavista) or inhouse Web Search sites so search confined to subset of curricula material |
| Object databases can be very useful for VRML and other data which is naturally of this form such as images and output of simulations |
Full HTML Index
Original Form of Data is mapped in batch or real time and stored in a database. This can be
|
| HTML VRML etc. is NOT natural storage format -- rather it is universal display format! |
| Local Client formatting to (HTML,VRML) needed for standard browser display standards |

Digital Video and Audio. This will enable collaboration and dissemination of fixed assets (audio/video clips) stored in multi-media databases or of information encoded in real-time.
|
| Note these are typically streaming and not "batch" approachs. Current default Web downloads video to client before playing and this approach cannot scale! |
| Can use traditional (relational) databases to store metadata and text with which to index video. |
| Digital video works well over ISDN (128 kbits) but for full screen needs about .5 megabits per second even with wavelets |
| This will be CNN/Network digital delivery technology for future infinite cable channel world |
Full HTML Index
Clearly digital audio and video supports the type of collaborative environments needed for cultural exchange
|
Digital video (in fashion similar to VRML 2.0) can be annotated to provide much more interactive version of classic documentaries
|
| Digital Audio and Video is currently less than 5% of web data but eventually it will be dominant (95%) form of digital information and serving will be major Web activity. |
Broad distribution requires ISDN-ATM speeds but can deliver from local WebServers as only needs Ethernet or less for each client

| We suggest that Universities historically are "approved" to give "licenses" i.e. certification that students have a certain level of knowledge |
| In the emerging Web based Virtual University, the traditional type and length of learening cycles is not obviously appropriate |
| Further we need to bootstrap WebWisdom and "suck customers in" a little bit at a time! |
Thus suggest Scalable Certificates
|
| Note these certificates are also portable as can take anywhere at any time! |
Traditionally, University courses are 1/3 interaction and 2/3 study/homework

We are experimenting with home care terminals based on David Warner's "neat thing" sensory front-end, with rehabilitation and disabilities as initial application target.
|
| This allows Doctors to interact with Patients at the Home with Instruments monitoring their health |
| But it also allows Disabled access to Web and to Education on the Web as "neat thing" allow us to replace Mouse/Key board input with any measurable human signal |
For structured data at least, we have full control over both Patient and User Interface.

| Most of the real world WebTop Systems will involve multi-user collaboratory modules. Even for scientific computing, complex toolkits such as WebAMR will be most conveniently supported by interactive consultation between developers and users. |
| Collaboratory multi-user components will be further enhanced in enterprise, commerce and community systems. |
| This is illustrated in our recent telemedicine prototype for nursing triage. Here we start from the collaboratory component involving nurses, nurse practioners and pediatricians and add HPCC components such as medical imaging and agent based diagnosis. |
| We view the Bridge topology (Warner & Balch '95), underlying such telemedicine systems, as a promising generic framework, applicable also for other problem domains. |
A generic bridge includes "points of need", "points of expertise" and intelligent middleware that manages information resources and provides connectivity between customers and optimal services.

| We present here examples of the bridge topology, instantiated in various application domains: |
| Domain Points of Need Points of Expertise Typical Services |
