  1. Design Lessons from Deployment of On-demand Video Liwei He, Anoop Gupta, Stephen A. White, Jonathan Grudin Microsoft Research

  2. Introduction • On-demand video talks are becoming commonplace • In fact, in the long term we may have • more online viewers than “in-room” viewers • more on-demand viewers than “live” viewers • This study focuses on: • Behavior of on-demand viewers • Implications for organization and delivery of on-demand talks

  3. Microsoft Technical Education (MSTE) • MSTE provides internal training for Microsoft employees • Live seminars • On-demand video website • MSTE on-demand video website (7/1997 – 6/1998) • 163 talks were digitized • User-actions are logged on the server • 2096 individuals and 6685 sessions • Over 115,000 records logged

  4. UI for MSTE on-demand video website Video VCR-like controls Slides Table of content

  5. Microsoft Technical Education (MSTE) • MSTE provides internal training for Microsoft employees • Live seminars • On-demand video website • MSTE on-demand video website (7/1997 – 6/1998) • 163 talks were digitized • User-actions are logged on the server • 2096 individuals and 6685 sessions • Over 115,000 records logged

  6. Questions studied • How long do viewers spend on each viewing session? • How does a viewer spend time within a session? • Do viewers use the table-of-content to jump around?

  7. Most sessions tend to be short

  8. Front part of the talk is watched more • Beginning of each slide is also watched more 70 60 50 40 User count 30 20 10 0 0 10 20 30 40 50 60 70 80 90 Nth minute into the talk

  9. Viewers do use table of content

  10. Conclusions • User behavior • Most sessions are very short • Front part are more likely to get watched • Viewers do use the table of content to jump around • Design implications for presenters of on-demand videos • Use inverted-pyramid style • Present key messages early in talk • Present key messages early in each slide • Use meaningful slide titles • Reveal talk structure in slide titles

  11. Work in progress • Extend the duration of analysis • Interview MSTE users • Use the user access pattern to generate video summaries • Read our latest results at http://www.research.microsoft.com/coet
