INFO 447 - L05 - January 19, 2005 Notes By: Prins, Serim, Fortier, Horm Vote for best paper: Heath '91: 1 Hollam '92: 8 Dourish '92: 7 Bly '93: 1 Interesting because some people really like the study of use and study of system. What do you get out of this unit? - Sense of community - Replicate face-to-face Video Brainstorm - Good Moving picture Visual Cues Better Sense of 3D space Archive Easy to duplicate/distribute Ability to shift time (record & watch later) Pause/Repla - Bad Extremely Attention Dependent Not always a perfect representation Who's talking Costs (decreasing) Not always portable Availability (not everyone can access) Formatting (Codecs) Overhead - admin on multiple ends Availiblity - Ugly High bandwidth Space (storage) Image becomes more important than content How do I look? (self-regulation) Piracy Standards/Compatibility Firewalls/Security Edits for Deception Focus - Image/content view People highlight some of the things on these list. Jonathan pays special attention to the strong points of video (archive, replay). Hollan & Stornetta "Beyond Being There" > Focus on communication, not comparison > Analogy: Crutch vs Running Shoe - Shoes enhance your best performance, whereas crutches just keep you up > Apply to MMORPG? > Accountability when talking in relation to Anonymity - Kind of on a scale > What about Anonymity outside of the workplace? - Probably not so ideal in a counseling envronment Dourish & Bly "Portholes: Supporting Awareness in a Distributed Work Group" > Low Bandwidth > Awareness > Get back some of the personal connections > What is porthole? - Application that updated images every 10 minutes - Can see their name and when the last image was updated > Interesting features - Low Bandwidth - Uses "relatively inexpensive equipment" - $10-15k for server (at the time) - $5k per camera > It is pretty cheap to do now... but not so cheap in the day of Vanilla Ice > Why not today? - Other alternative? - Privacy Concerns? > Think about the Navy ship example - It's almost there - Kind of like surveillance > Where is the line drawn between "awareness" and surveillance? - 2-way vs 1-way - Ability to opt-in/opt-out > Awareness - You're not watching it all the time Talk about the lab that we pwned! Uncharitable attribution (in the IM papers last week) > Assuming something about someone because, for example, somebody won't reply IMs right away. > Are they just stupid?
