Breakout Session Summary Transparencies

What are the issues?

Group 1

Issues

• Variables = Channel
  • device, modality, target language, synch device, navigation model, author intent, user intent
• New devices
• Easy authoring
• Clarify devices
• Standards must address conformance to reference model
• Not one page fits all, but attempt it
• Author independent of channel but not unaware
• Look and feel independent of browser (eg WAP)
• Application needs the ability to determine the capabilities of the device

Approaches

• Programming model to deal with diversity
• Conformance & classification

Priorities

• Both 1 & 2 important
• Focus
  • even split
  • also easy authoring

Should the author be able to force design will, or should the user make a choice?

Group 2

• When is special authoring necessary for multiple channels?
• What markup should be used for authoring content that is channel-independent?
• How can content be selected for use with specific devices or preferences?
• Can solutions scale from single author to large-scale authoring?
• Multi-modal solutions are very different from text-only.
• Can we capture a range of scenarios that should be considered?

Group 3

• Interaction & flow
  • user/author dialogue facilitated
• Real world concerns
  • development and deployment.
  • educating users, developers, how it all fits together.
• (Im)possibility of separation of content, presentation & interaction
  • fidelity of semantics / capturing intent
• Accessibility of devices – must ensure all new devices are accessible to disabled users.

Group 4

• How to make intent explicit (describing function)
• High level descriptions (screen readers)
• Try to use common markup where practical for voice / visual
• Move burden from authors to UA [User Agent]
• How far can we push dialogs?
• Need for common framework to express semantics

• How to handle scripts in a device independent way
• How to deal with old / existing content
• How to deal with old browsers (many people don’t update their browsers frequently, legacy issue)

• Ways to describe classes of devices
• Automatic discovery of UA’s
• SMIL Switch -> different devices
• Where / when to transform / adapt (bandwidth issue)
