Intro for EdCU talk:
Hullo! My name is Anoop Gupta. I lead a group in the areas of Collaboration and Education at MSR. Today I will like to introduce you to some projects that we are doing that are relevant to the education context.
Let me begin by saying a few more words about our group. ...
As we head into the 21st century, it represents a major turning point for our society. As we head into the next millenium, we clearly leave the industrial age behind and step into the information age. Ability to gather, sift thru, assimilate, synthesize, reason with, and create new information will be skills critical to survival and success. A solid education will no longer be an option, but a necessity.
While we are at the brink of this change, we find that our education system has not changed in a long time, both pedagogically and institutionally. Pedagogically,
.. A person entering a classroom from 50 years ago will feel quite at home
As Elliot Soloway from U. Michigan once put it, in majority of our classrooms, we still take one piece of stone and rub it on another to teach.
I am not here to say whether what we are doing today is right or wrong (because there is little research to say otherwise), but what does seem clear is that there is not a lot of questioning that is going on about whether there is a better way to do it...Intro for EdCU talk:

2. Collaboration and Education Group Formed about 12 months ago
Mission:
To explore novel technologies and applications that enhance collaboration and education / training
Current work focuses on streaming media
Research model
Evaluation: Laboratory and Field Studies
3. Focus on Communication Effective access/use of information is key to a modern corporation (Digital Nervous System)
Much of this communication can be considered presentations, formal or informal
slides and documents capture only a small part
low-cost capture and on-demand availability
Relevant participants are often not collocated
must create sense of presence and awareness
provide interactivity across time and place
4. Three Issues that Frame Our Research There are too many presentations to attend
ability to time-compress talks
ability to summarize talks
indexes for quick search/access
Knowledge-creation does not end when the talk ends
facilitating in-context asynchronous discussion
Talks redesigned for online and asynchronous access
social implications
changes in organization and presentation of talks
5. Ongoing Projects MSTE and MURL: Online Seminars
Time Compression and Skimming
MRAS: Multimedia Annotations
Flatland: Telepresentation System
8. MSTE Online Presentations Logs of ~10K sessions involving over 2K users
Some results:
On-demand audience about 40% of live audience
60% < 5 minutes
Viewers jump around video
Initial portions much more likely to be watched
Presentations will be designed differently in future
Present key messages early in talk
Present key messages early in slide
Use meaningful slide titles
Reveal talk structure in slide titles
Consider post-processing talk for on-line viewers

10. Time Compression: Synchronized Audio and Video To preserve pitch: throw away portion of each 100ms chunk, then stitch together
Basic signal processing well known, but several systems issues
Results of lab studies:
People choose ~1.4 speed, dont adjust much
They like it
I think it will become a necessity
Once people have experienced it they will never want to go back. Makes viewing long videos much, much easier.
Comprehension may go up
13. Skimming: Compression Goes Nonlinear To beat 2x speedup, must throw away content
Sources of information
audio: pauses, intonation, speech-to-text and NLP
video: scene changes
other: slide-changes, previous viewers patterns
Lab studies of 4x-5x speedup
Viewers learn from automatic summaries
Viewers like and learn more when author-edited
Mixed-initiative summarization is promising
14. Ongoing Projects MSTE and MURL: Online Seminars
Time Compression and Skimming
MRAS: Multimedia Annotations
Flatland: Telepresentation System
16. Initial Lab Studies of Annotated Video Personal note-taking (MRAS vs. Paper)
~1 note / minute in each condition
positioning: none in paper; ~10-15s later in MRAS
all subjects preferred MRAS (although more time), and thought more useful for future reference
Shared notes study
text preferred to audio
14/18 stated more participation than in live class
auto-tracking particularly useful Also talk about experiments being conducted with Stanford this quarter in EE-182. Both the mission and the problems encountered.Also talk about experiments being conducted with Stanford this quarter in EE-182. Both the mission and the problems encountered.
17. Annotation: Field Studies & Future Work MSTE class to use MRAS and recorded lectures
Can we emulate live-classroom discussion in an asynchronous environment using MRAS?
Will people interact/learn more using MRAS rather than in live classroom environments?
How can we stimulate discussion / community formation in asynchronous environments?
MS Usability Engineers: highlights tapes
Video is now organized by annotations
Email distribution, playlists become key features
Possible wider use in development
Unified annotation platform architecture
storage, naming, sharing, user interface
18. Flatland Telepresentation System Joint project with the Virtual Worlds Group
Flexible architecture for rapidly prototyping distributed collaborative applications
19. Flatland
20. Flatland Telepresentation System Joint project with the Virtual Worlds Group
Flexible architecture for rapidly prototyping distributed collaborative applications
Initial use in 3 multi-session MSTE classes
Presentations from desktop to remote audience
Students:
Liked the convenience
Liked ability to multitask
Did not think learning suffered
Instructors:
Missed familiar sources of feedback
Comfort level rose over time for 2 of 3
Overall: Lack of awareness of others a key problem
21. Telepresence: Issues Being Explored Can capture and replay telepresentations:
Opportunity to integrate compression, annotation
Examining mixed live/remote audience designs
Enhancing sense of presence and awareness
Merging real-time and asynchronous information
