Jim Larson - Ergonomic and End user oriented issues

 1. When is multimedia really useful versus monomedia.

Handsets are not ideal for multimedia. Handsfree or
distant microphone operation would be helpful.

 2. Social interaction issues:

  - Privacy
      * Eavesdroppers
      * Appearing stupid in front of other people

  - No cell phone allowed in theatres

  - Not structured for a social role

 3. Voice is emphemeral (it doesn't hang around)

  - a record of what was said could be useful

 3.  Is the device on a phone, handheld, new thing?

  - what is the migration path to this new thing

 4. Input device problems

  - buttons hard to use with big fingers

  - device is inadvertently turned on

  - thumb fatigue

 5. Solutions

  - enourage research on when multimodal interfaces
    are really useful

  - research on minimizing number of user actions/gestures
    to achieve particular input actions

  - involve social scientists to look at what people like
    to do/not like to do, etc. To get a better feel for
    appropriate useage models and constraints

  - design and implement social protocols for privacy and
    social interaction

  - design and implement a persistent visual channel (kind
    of like a short term memory) as an aide memoire

  - capture and publish use-cases for multimodal devices/apps

  - a roadmap for getting there from here

  - ability to keep going or at least to suspend and recover
    when access to server is temporarily removed

  - cultural sensitivities to use of color etc.
