NEEDS

DESIGN

EVALUATE

IMPLEMENT

Research: Using video to support collaboration
  • My research focuses on supporting collaboration (CSCW)
  • Uses ethnographic studies for need-finding
  • Example of design process, differences from popular trends
popular high f idelity v ideo c onferencing
Popular: High fidelity video conferencing
  • Cisco Telepresence
  • HP Halo
  • Polycom Real Presence Experience

High fidelity video and audio

cisco telepresence
Cisco Telepresence
  • Target audience: Company Executives
  • Rules of Telepresence
    • Present far end participants life size
    • Provide virtual eye contact
    • Do not pollute visual display with distractions

Are these the main needs for successful everyday collaboration?

  • Integrated into all Macintosh computers
  • Very easy to use
  • Attractive graphical presentation

Are these the main needs for successful everyday collaboration?

aware ness cues for remote collaboration
Awareness cues for remote collaboration
  • Hard part is social problem
    • Gracefully sharing a workspace
  • Cues for negotiating interaction lost among remote collaborators (i.e., phone)
  • Review research prototypes for remote collaboration
    • VideoDraw
    • VideoWhiteboard

Innovation in mediated support for collaboration

ethnography
Ethnography

Branch of anthropology that deals with the scientific description of specific human cultures

  • Typically applied to study of foreign cultures
  • More recently applied to work cultures or simply users of technology
