What is Data Collaboration?

Data Collaboration Standards

Approaches to Data Collaboration

Section Overview

Page 3: Data Collaboration

3

• A “third stream” in addition to audio and video

• A shared electronic document

• A view of an electronic workspace

• A shared interface to a running application

• A one-time, impromptu or planned engagement

• A persistent, group electronic workspace

• Synchronous or asynchronous

What is Data Collaboration?

Page 4: Data Collaboration

4

Classroom: Shared whiteboards, slides, browsers; chats and polling/quizzing; curriculum planning, course design and repositories

Administration: Proposals, budgets, status reports

Research: Modeling/simulation, visualization, remote control

Medicine: Collaborative discussions, remote diagnosis

Typical Uses

Page 5: Data Collaboration

• Whiteboard• Chat or Instant Messenger• Shared Documents (Still

Image)• File Transfer• Shared Applications• Remote Control• Pointers• Surveys, Polling, Quizzing• Recording• Telephone and/or VC

Bridges• Video Streaming• Animation Support

• Chair Control• Scheduling and Timers• Agendas for Meetings,

Classes• Announcement Boards• Participant List, Status panels• Management Console• Directories• Logging, Tracking• Security

- Authentication- Encryption

• Shared Repository, Meeting/Class Archives

Approaches

Remote Data Display

Interactive Data Collaboration

Shared Persistent Virtual Workspaces

Page 8: Data Collaboration

8

With a projected image:

• Share a PowerPoint or other presentation

• Share display of web browsing

• Demonstrate an application

• Provide user assistance or training

• Share whiteboard sketches and text

Remote Display

Page 9: Data Collaboration

Methods

• Scan converters

• Advanced proprietary solutions

Band

• In-band (on a video channel)

• Out-of-band (on an independent data

channel)

Remote Display

Page 10: Data Collaboration

10

Scan converters

–Converts a high resolution PC RGB signal to a lower resolution composite video signal

–Cheap and easy to use

–Fair to poor resolution (no small fonts)

–Uses a (the) main video window (in-band)

Remote Display

Page 11: Data Collaboration

11

Proprietary solutions - Polycom Visual

Concert FX

–Local RGB video from PC, sound from mic to far-side video or projector/display

–Easy to use but requires high-end video conferencing appliances

–High quality, native resolution–Uses a separate window (out-of-band)

Remote Display

Page 12: Data Collaboration

12

Proprietary solutions - Polycom SNAP!

–Transmits JPEG

snapshots of desktop or

application to a Polycom

appliance–Free and relatively easy

to use –Low resolution like scan

converter–Windows only

Remote Display

Page 13: Data Collaboration

13

Share a desktop or a window to:• Co-browse the web• Jointly work on whiteboard diagrams• Jointly update a document

Share a running application to:• Jointly steer its operation• Provide support or training on its use• Troubleshoot problems• Use valuable, limited resources

Define a meeting space

Persistent Virtual Workspace

With remote collaborators, in a virtual workspace:

–Use capabilities of interactive data collaboration

–Collaborate over time on a project or activity

–Maintain the work record: documents,

discussion, digital objects, notes, outlines

Bandwidth requirements

Browser based and centralized tools may be influenced

more by network latency and virus problems/DoS attacks.

Sustained workflow

Newer tools have features that support persistent

environments as well as ad-hoc meetings.

Availability

Commercial tool pricing for general (mass) use is

probably an obstacle. Project pricing may be reasonable.

Closing Remarks

Page 48: Data Collaboration

Methodology

While many use open standards for individual

elements, overall architectures and interfaces

tend to be unique and even proprietary.

Perspective

Venue or perspective must be chosen: desktop,

meeting room, classroom, others.

Ease of use

Tools are not always intuitive.

Substantial training may be required.
