Browsing Video

Part A - Lecture browsing

Before you start part A, you will need to find a partner to work with in the class. If you can't find a partner, send mail to Alan Liu, and he will match you up with some one.

Part A is to skim video lectures under time constraints to construct a outline. The scenario is that you are to write a one page outline of a lecture you supposedly went to, your boss is very interested in what the lecture was about - however you blew off the afternoon, and did something else. Fortunately, there is a video archive available, unfortunately, you are very short of time.

You will watch three lectures, one you will give yourself 30 minutes to watch, one you will give yourself 22.5 minutes, and one you will give yourself 15 minutes to watch. You are to use the player to skim the video - the seek control allows you to skip ahead or back. After you have watched each video, write a one page. When you have completed your outlines, send them to your partner. Your partner will read your outlines, and attempt to determine which is based on 30 minutes, which ic based on 22.5 minutes, and which is based on 15 minutes.

Choose one of the following groups of videos to watch. You will need to agree with your partner on what to watch. Avoid lectures that you are familiar. The lectures have been grouped so they are somewhat similar.

Group A  Industry
Bill Schilit, Dec 4
Udi Manber,  Nov 20
Rob Short, Jan 27
Group B   Machine Learning
Marina Meia, Oct 23
Michael Jordan, Dec 11
Claire Cardie, Jan 13
Group C  Architecture
Doug Burger, Nov 13
Kathryn McKinley, Feb 5
Mor Harchol-Balter, Nov 18
Group D   Industry
Dave Tennenhouse, Oct 15
Usama Fayyad, Oct 17
Bud Tribble, Jan 23
Group E   Systems
Dan Grossman, March 20
Chris Olsten, March 11
Eddie Koeller,  April 17

Use good experimental procedures for this - view all three videos under similar circumstances. Choose the group (with your partner), and then randomly decide the order of the videos, and how long you will watch each one. It is recommended that you before you watch any of the videos, you practice skimming another video, so you aren't figuring out the player's controls on the first video.

Part B - Time compression

Part B is to look at a video with time compression. Some of the UW colloquia are available at 1, 1.25, and 1.5 speedup. Watch a short segment of one of these (say five minutes) under the three different speeds. Briefly describe your reaction - would you choose to watch the entire colloquium sped up? At what setting?

The 1998-1999 colloquia seem to be available with compression. http://norfolk.cs.washington.edu/htbin-post/unrestricted/mmedia/ondemand_colloq.cgi?year=1998&sortby=0 If you have difficulty choosing one, I suggest Anoop Gupta's lecture.

What to turn in:

Submit your outlines, along with a summary of how you created them. What were the skimming strategies that you used. Give a brief comparison between your outlines and your partners. Would the task have been significantly different if you were asked to produce lecture summaries instead of outlines. How much time do you need to create an outline of a talk based on the video. Are the player tools adequate? For part b, give a brief evaluation of your experience in watching videos with time compression.
