Instant success?

Thursday, September 9th, 2010 by Gene Golovchinsky

So I fired up IE-8 and I tried Google Instant. It’s fast: as fast as I can type, it’s showing me search results. Mind you the results aren’t always sensible, but they are delivered quickly. It works great for short queries such as looking for a popular sense of some word. In this case, it saves me the trouble of hitting enter. Nice, but not earth-shattering.

When I am looking for something less obvious, it guesses wrong. For example, the query “information processing and management” (an academic journal) first produced a set of results for the partial string “”inform” that match informatica.com. Nice, but not the journal. After I typed “information,” it showed me the wikipedia page for “information” (oh the irony) and a bunch of other links highly-associated with the term. But no journal. “information proc” produced a bunch of hits on “information processing.” Better, but not what I am after. Completing the second word and pressing the space bar yielded a number of links to “information processing theory,” which also happens to be the top query suggestion. But no journal. Only when I typed “information processing and” did I get the results I wanted.

So what are we to make of this new addition to Google’s bag of tricks?

Affect and design

Wednesday, September 8th, 2010 by Gene Golovchinsky

Daniel Tukelang wrote an interesting review/commentary on Clifford Nass and Corina Yen’s new book on affective computing, where they cite many examples that biasing results toward one’s expectations can improve users’ satisfaction with the results. Another class of responses (that is also well-documented in the affective computing literature) is the tendency for people to anthropomorphize computers.

Daniel’s conclusion is that it’s relatively straightforward to use these techniques to deceive people, to subvert personalization, to mislead rather that to inform. I’ve got two reactions to this work, one related to system design, and one more specifically to information seeking.

Twitter for iPad

Friday, September 3rd, 2010 by Gene Golovchinsky

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.

Gaming learning

Tuesday, August 31st, 2010 by Gene Golovchinsky

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.

App as silo

Monday, August 30th, 2010 by Gene Golovchinsky

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.

HCIR Search Challenge

Thursday, August 26th, 2010 by Gene Golovchinsky

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.

Comments and annotations

Wednesday, August 25th, 2010 by Gene Golovchinsky

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.

Session-based search slides

Friday, August 20th, 2010 by Gene Golovchinsky

Here are the slides of the presentation I gave at the IIiX 2010 conference. I presented work done in collaboration with Jeremy Pickens on session-based search. The paper is here; the talk highlights some of the theoretical considerations and gives some examples of the new interface we’re building.

Prezi

Monday, August 9th, 2010 by Gene Golovchinsky

In today’s business and academic circles it’s rare to see a presentation that doesn’t involve PowerPoint (or its Mac cousin, Keynote). For better or for worse, we’ve grown accustomed to the visual cueing and pacing functions that these tools provide, both as audience members and as presenters. This mode of presenting has become so entrenched that all manner of problems have been ascribed to over-reliance on these kinds of presentations.

Thus its interesting to see attempts at innovation in this space. In particular, I am thinking of Prezi, a recent startup that is pushing a more interactive, hierarchical presentation model in which you can move from overview to details and back in smooth transitions, and rather than structuring your presentation around a single narrative, you can define multiple aspects that can be explored interactively. In addition, Prezi has neat-o animated transitions among the views you define.

So does this mean that Microsoft’s stranglehold on presentation software is at and end?

Papers, now with notes

Tuesday, July 27th, 2010 by Gene Golovchinsky

I was excited to see annotations mentioned in the description of the updated Papers app for the iPad, but was disappointed in the execution. They added two kinds of annotations: text notes and highlighted passages. While both are useful for active reading and appropriate given the characteristics of the device, the implementation left a lot to be desired.
