I played a bit with the Twitter for iPad app (announced recently on the Twitter blog), and found it a pleasant experience for casual use, but not particularly well-suited for more intensive use that involves multi-tasking. The slide-over pane organization is elegant and more usable than TweetDeck for iPad’s browser. It works particularly well for reading web pages in portrait mode: pages can be zoomed to hide the ads and show just the main column in a reasonably-sized font.
The IIiX conference series (the latest installment of which took place recently at Rutgers University) arose from IRiX (Information Retrieval In conteXt) workshops (2004, 2005) held in conjunction with SIGIR 2004 and 2005. The workshops were organized by what I think of as the Scandinavian contingent of the IR community — the likes of Peter Ingwersen, Kalervo Järvelin, Pia Borlund, Birger Larsen and others — who collectively represented a more user-centered (as opposed to system-centered) approach to studying information retrieval. Yes, others were involved, but it still seems that the Scandinavians somehow inspired and led the movement. Given the success of the workshops, they organized the IIiX conference series to create a more formal venue for these topics.
One of the highlights of the 2010 conference was a debate between the system camp and the user camp about the value of simulating users. (See Saturday August 21 in the program.) This was a reprise of the theme of a workshop held at this year’s SIGIR conference, this time on the other side’s turf.
Daniel Russell wrote up a nice summary of my search for the origins of Daniel Tunkelang’s name. Daniel R. drew two lessons from the exercise: one, that social search (although I would say the social was bordering on the collaborative, in this case) can be effective because it integrates insights of multiple people; and two, that some domain knowledge helped me navigate the search results more effectively.
I’d like to expand his second point a bit.
If you’re in the business of conveying information to people, you might be interested in engaging their interest to cause them to seek out more information and to deepen their understanding of the data. That’s the premise that Nick Diakopoulos is trying to explore with some interactive visualizations of demographic data.
Nick (a former FXPAL Intern) is exploring the design space of interactive, semi-automated visualizations that can be put together quickly and yet leverage the kinds of interaction design characteristic of computer games.
A little while ago I wrote about the lack of details in reports of iPad/eBook use for education; I am happy to point to an article that gets it right. Joel Mathis surveyed some recent efforts by universities to use the iPad to replace some more traditional educational materials. He reported on some specific apps that one university was considering using (although the textbook app by ScrollMotion appears to be in development, as I wasn’t able to find any details on this app other than the Februrary 2010 announcements. According to another article, the tool would integrate multimedia textbooks with note-taking and other features. Does that mean that the notes would be attached to the textbook app, or could they be exported and integrated with notes on other materials?
This is a specific instance of a more general pattern of data use on the iPad: with each app holding on to its own data, it’s difficult to see how to manage notes and annotations across several applications that are required for one’s studies or work.
Ten days ago, a theoretical computer science community Q&A site went beta and seems to be generating a fair amount of activity. I’m a big fan of MathOverflow, and am delighted to see a similar site springing up for a different field.
Thirty-nine days ago, a new mathematics site went beta, which initially puzzled me since the mathematics community already has the highly successful MathOverflow site. The difference appears to be that MathOverflow is specifically for research mathematics whereas the new site aims to be broader, allowing more elementary questions.
Overall, I think a proliferation of such sites is great, but it is also confusing. It isn’t always clear when a question is research level or not. There are questions tagged algebra or topology on the CS theory site that are pure mathematics questions. There’s a question tagged graph theory that had been posted previously to MathOverflow. I am delighted to see that both cs.cr.crypto-security and quantum computing already are populated with a few questions, but similar questions in these areas received good answers on MathOverflow. It would be a shame if the proliferation of sites lead to less interaction between fields rather than more. I’ll be curious to see how the usage patterns play out over time.
The fourth HCIR workshop was held this past weekend at Rutgers University in conjunction with the IIiX 2010 conference. This was, in my opinion, the best workshop of the four so far. Part of the strength of the workshop has been the range of presentations, covering more mature work in traditional 30 minute presentations, a poster and demo session, and, new this year, reports from the HCIR search challenge.
From the web site:
The aims of the challenge are to encourage researchers and practitioners to build and demonstrate information access systems satisfying at least one of the following:
- Not only deliver relevant documents, but provide facilities for making meaning with those documents.
- Increase user responsibility as well as control; that is, the systems require and reward human effort.
- Offer the flexibility to adapt to user knowledge / sophistication / information need.
- Are engaging and fun to use.
Participants would be given access to the New York Times annotated corpus which consists of 1.8 million articles published in the Times between 1987 and 2007, and they would be expected do something interesting in searching or browsing this collection.
While traveling I have been doing more work on my iPad, some of which I had previously done on paper or on my laptop. I’ve been reading and reviewing conference papers, making UI design sketches, and writing longer chunks of text such as this blog. The experience has been informative, but not altogether positive.
I recently found an interesting collection of student literature review/position papers from Umeå University related to a range of CS and HCI issues, including mobile technology, ubiquitous computing, table-top displays, etc. Among them was a paper by Alan Larsson that examined the role that slate-like tablet computers can play in education. It examined requirements for such devices both from the instructor’s and from the students’ perspective, analyzed them on several dimensions, and then compared three devices — an iPad, a (perhaps soon to be released) Android tablet, and an older-generation tablet computer — for their fit to the various tasks.
For about 20 years the cast of Mystery Science Theater 3000 has been entertaining science fiction fans with funny commentaries of bad movies. The concept is strangely simple: mad scientists (at various times: Trace Beaulieu, J. Elvis Weinstein, Frank Conniff and Mary Jo Pehl) have launched a man (Joel Hodgeson and later Michael J. Nelson) into space and are forcing him to watch the worst movies ever made. To keep his sanity, the unfortunate spaceman and his robot friends (at various times: Beaulieu, Weinstein, Kevin Murphy, Bill Corbett and Jim Mallon) make fun of these movies. The original show was canceled about 10 years ago but most of the people involved are still riffing on cheesy movies – “the worst they can find”.
