Case-based reasoning for procedure learning by instruction
By Jim Blythe and Thomas Russ (USC Information Sciences Institute)
Summary:
This paper discusses a new tool to assist the user by "procedure learning by instruction". Their solution is based on utilizing previous procedures, and call them "cases". From these cases, they can aid the user in instructions and resusability. They apply this concept to a case-based reasoning system called CB-Tailor. This system allows for user to find specifics on distance to a restaurant or other attraction while traveling. From their test, it was a useable tool for both the novice and expert user.
Discussion:
This paper lacked a user stuy or any support information about how the users used the system.I finished the article missing the advantages of using a case based approach for improving instructions.

IUI 2008 - Find me if you can
Find me if you can: Designing Interfaces for People Search
By Junichiro Mori, Nathalie Basselin, Alexander Kroner, and Anthony Jameson (German Research Center for Artificial Intelligence)
Summary:
The article discusses people selection interfaces and provides two sample applications that assist in locating specific people for a given use.Searching for people is similar to searching for an article, everything is based on a given criteria. Next, the researchers define three types of data: user model-based, context-based, and relationship based. Examples provided are for the Community Browser (people are placed into categories) and Reaching People (assists in making contact with selected individuals through email or social networking tools). Both examples are functioning in two applications. To conclude, the researchers emphasize that this type of search is needed for collaborative work situations.
Discussion:
I found this paper to be lacking in detail. It introduced the topic of people searching for group projects, but did sufficiently describe who would have access to these types of searches. I see how in a large company this type of search could speed up team formations, but I am not sure if they should be open access to the general public.

Opening Skinner's Box
Opening Skinner's Box
By Lauren Slater
Summary:
Slater explores 10 great psychological experiments and provides an interesting perspective on the lives behind these great scientists. Also, she displays her vulnerability by opening about her life, experience, and family.
Chapter 1: This chapter delves into the life of the famous neo-behaviorist, B.F. Skinner. She talks to his family and enters his home to gain insight into the man who developed the theory on operant conditioning.
Chapter 2: Next, Slater enters the world of the 1960's and revisits the Stanley Milgram Project: Obedience to Authority.
Chapter 3: If you ever wondered how simple it is to "play crazy" and spend time in a mental hospital, then this chapter has you covered. Slater provides detail on David Rosenham's experiments about diagnosing the insane and then conducts the experiment in modern day.
Chapter 4: Then Slater discusses the work of John Darley and Bibb Latane on the effects of being in a group and its impact on personal responsibility.
Chapter 5: This chapter describes how Leon Festinger discovered "cognitive dissonance".
Chapter 6: Slater candidly explores Harry Harlow's monkey experiments that still make my skin crawl weeks after reading the chapter.
Chapter 7: Then Slater notes on the complexities of addiction through the work produced by Bruce Alexander.
Chapter 8: After reading the experiments by Elizabeth Loftus, it leaves you wondering if all of your childhood memories are true.
Chapter 9: Moving further into the subject of memory, Slater share the sea slug experiments of Eric Kandel and his great advances in neuroscience.
Chapter 10: The last chapter ends with Antonio Moniz's discovery of the lobotomy and its implication in today's surgeries.
Discussion:
This was my favorite book for the semester! I enjoyed her opinions and personal stories. It was a brief introduction to many experiments that have an impact in our lives and HCI.

IUI 2008 - Temporal semantic compression for video browsing
Temporal semantic compressoin for video browsing
By Brett Adams, Stewart Greenhill, & Svetha Venkatesh (Curtin University of Technology)
Summary:
The article discusses a new approach to display video streams with the Temporal Semantic Compression (TSC). A web browser with TSC grabs a video input and collects a "time based measure" on the video information. Next, it resamples the video dynamically to improve real time interaction.
Implementation
They have a designed a standard default video browsing widget with two features: compression control and context area. So, by manipulating the compression control, it will add or delete shots. An example of the compression, can be seen below on the movie, The Matrix.
Figure 4. Context overlay changes with compression,
centered on Escape Sequence: 94% Sequence bracketed
by two significant events; 80% Includes two sub-sequence
events, fire and escape on foot; 50% Detail includes dialog
giving rise to escape on foot; 0% Original video
From their trials, using the controls appears intuitive for the users. Also, it is planned to continue user testing on the browser.
Discussion:
I find this field to be interesting and informative. Anything that enhances the browser experience for the user, in my opinion, is a good thing. I will be interested in seeing if there are products similar using this approach today.

IUI 2008 - Who, What, Where, & When
Who, What, Where & When: A New Approach to Mobile Search
By Karen Church & Barry Smyth (University College Dublin)
Summary:
This article discusses the increasing popularity of searching the internet on a mobile device and how interfaces must adapt their content to suit these users. Church and Smyth offer a "new search browser interface" to help in delivering improved search queries and content. Their browser marks information of location and time of users, and delivers the new related queries that correspond to the marked previous queries.
Prototype
The prototype focuses on entertainment and tourism sites in the Dublin area. First, the user sees a map of their current place and it displays the "recent queries and result-selections" that have been seen by other users in the same location as red and yellow markers. The user then can filter the queries by time or preferences.
As noted in the article, their prototype proved their application delivers a unique search experience. However, no data was presented on the user's opinions/experiences with using the prototype.
Discussion:
This article is interesting and brings up the important point that applications must be unique for mobile devices. By adjusting to the benefits and limitations of the mobile phone, we can enhance the user's interaction and experience. However, I would have liked to see data, such as a user study, to see how a typical user interacts with the product.
