FXPAL has a few papers appearing at the upcoming ACM Multimedia Conference in Firenze, Italy.  Among them is NudgeCam, which was recently featured in an article on MIT’s Technology Review as noted previously on this very blog.

NudgeCam is an experiment in “active capture”. Media capture (in this case, photos and videos) is enhanced by providing a template of elements to capture and also real-time interactive tips to aid the quality of each shot or clip.  The template allows the author to insure that essential story components are captured, and the realtime feedback helps insure that the parts are of high quality. Together the creation of high quality result is streamlined.

The author, Scott Carter, will be presenting this work on Tuesday, October 26th in Session S1 at ACM Multimedia in Firenze, Italy.

See you there!

I am saddened to hear that Benoît Mandelbrot has passed away. His The Fractal Geometry of Nature excited and intrigued me when I was in high school, though I admit that while I, like many others, examined all the pictures, I read only scattered parts of the text. The talk of his I attended as an undergraduate was the first technical talk by a famous mathematician that I understood, essentially, in full.  The popularity of fractals was due to the gorgeous pictures,  and was aided by the simplicity of some of the underlying mathematics, which made it accessible to so many, and to the connection of fractals to so many phenomena. That fractals appeared at all scales in nature, from galaxies, to coastlines, to trees, I knew from looking at his book, but their tie to economics was new to me. He struck me as arrogant, but in an endearing way since his pride in his contributions stemmed from his intense love of the work and his absolute conviction of its importance. He clearly enjoyed his maverick status as someone who worked in a different way than most mathematicians, and on non-standard mathematics. Although he taught us to look for self-similar patterns throughout the universe, we won’t find the like of him any time soon.

FXPAL has immediate openings for regular full time employees and visiting scientists with research interests in the following areas: cloud computing, computer vision, multimedia applications, location-aware and event-processing applications, interactive documents, mixed reality environments, and database systems.

Candidates should be interested in working on practical applications in a collaborative setting. Regular full time positions require a Ph.D. in Computer Science or related field and strong development skills. Visiting Scientist positions require an extensive record of research contributions and experience.

Update: See the FXPAL web site to apply

A writer for the TC blog, Erick Schonfeld, recently posted a description of an encounter he had with a Stanford student at a drug store trying to recruit users to experiment with a paper prototype. The prototype and study were being carried out as a requirement for an HCI course the student is taking. The TC writer, in short, found the whole experience ridiculous, especially with respect to all of the whiz-bang, interactive demos he is used to seeing. While, as many point out, paper prototyping is a standard technique in HCI, that does not mean that it always works or is always appropriate. In fact, in my experience with early stage prototypes I was overall underwhelmed with paper prototyping. But I realized over time that experience did not reflect a problem with the prototyping tool per se, but rather a lack of understanding of the context of the user.

AT&T Bell Labs has recently made their entire archive of the Bell Systems Technical Journal (BSTJ) available for free on-line. The collection goes all the way back to 1922. In fact, the first issue has an article on the transmission characteristics of the submarine cable. For example, in 1978 an entire issue of the journal was dedicated to a new operating system called Unix.

The September-October issue of ACM interactions includes an essay by Don Norman and Jacob Nielsen in which they critique various aspects of gestural interactions as implemented on the new crop of touch-enabled devices: the iPhone, iPad, the Android family, and the like. The gist of their concern is that the design of these interfaces, while incorporating useful and pleasurable interactions based on touch (swipe, pinch, etc.) also introduce a range of usability problems well known to the HCI community.

Ken Hinckley, Koji Yatami, and several other people from MSR published an interesting analysis of how to combine pen and touch input on table-top displays. The work draws inspiration from observations of how people manipulate paper to derive design guidelines for bi-manual and bi-modal interaction. The paper contributes a thorough description of integrated touch and pen-based interaction and offers a thorough analysis of design principles that underlie these kinds of interactions.

Fox@fury is an interesting blog I have started following. Kevin Fox displays a keen design eye for offering small usability improvements that can potentially yield important usability benefits.

In a recent post, for example, he offered a simple suggestion for how to alter the appearance of Chrome tabs to improve the user’s ability to determine which of many open tabs is active. In another, he analyzed the Android app market to show some of the fundamental flaws in its design.

Michael Bernstein and a cast of thousands published an interesting paper at UIST 2010, which was honored with the Best Student Paper award. The paper describes and evaluates Soylent, a tool that uses Mechanical Turk to generate corrections and suggestions to improve writing. (The name Soylent is not a substitute for dairy in the weeks leading up to Easter; rather, it is derived from the film Soylent Green.)

This work is interesting in a number of ways: it automates the distribution and collection of Mechanical Turk tasks and then integrates the results into an interactive system, it recognizes the limitations of fully-automated approaches, and it suggests a design pattern that can be applied in other contexts .

The main contribution of this paper is the idea of embedding paid crowd workers in an interactive user interface to support complex cognition and manipulation tasks on demand. These crowd workers do tasks that computers cannot reliably do automatically and the user cannot easily script.

Daniel Tunkelang wrote an interesting post about the merits (and lack thereof) of software patents. The basic argument is that software patents are overly broad, hard to defend against, are not central to most software companies’ businesses, and only truly benefit attorneys and patent trolls.

I won’t pass judgment on the industry as a whole, as I am sure there are many legitimate cases, but I will point to some evidence to suggest that the patent mechanism, in its essence, is the wrong mechanism for protecting these ideas.
