– 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

Approaches

Remote Data Display

Interactive Data Collaboration

Shared Persistent Virtual Workspaces

9

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

10

Methods

–Scan converters

–Advanced proprietary solutions

Band

–In-band (on a video channel)

–Out-of-band (on an independent data

channel)

Remote Display

11

Scan converters

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

–Cheap and easy to use (~$100)

–Fair to poor resolution (no small fonts)

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

Remote Display

12

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

14

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

49

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.
