Reviewing the reviewers

on Comments (11)

I’ve written about some alternatives to the current review process, and I believe one of ways in which the current process can be improved is by formal recognition of reviewers’ efforts. While many conferences and journals acknowledge reviewers by publishing their names, this does not reflect the quality of the effort put in by some reviewers. A more lasting and public recognition of quality reviewers may be one way to improve the quality of this volunteer effort.

Interestingly, the APS recently instituted a policy of recognizing referees who review the articles submitted to the various APS journals.

The basis for choosing the honorees was the quality, number, and timeliness of their reports, without regard for membership in the APS, country of origin, or field of research. Individuals with current or very recent direct connections to the journals, such as editors and editorial board members, were excluded.

Renewable energy from slow water currents

on

People have been trying to harness wave energy for decades, and of course more traditional – and more destructive – hydroelectric projects like dams provide power to hundreds of millions of people. Now, researchers at the University of Michigan are creating a system for fish-friendly power generation from slow-moving water currents in rivers or oceans – and it’s not that expensive; about a third the cost of cheap solar. Here’s the story:

Slow-moving ocean and river currents could be a new, reliable and affordable alternative energy source. A University of Michigan engineer has made a machine that works like a fish to turn potentially destructive vibrations in fluid flows into clean, renewable power.

The machine is called VIVACE. A paper on it is published in the current issue of the quarterly Journal of Offshore Mechanics and Arctic Engineering.

VIVACE is the first known device that could harness energy from most of the water currents around the globe because it works in flows moving slower than 2 knots (about 2 miles per hour.) Most of the Earth’s currents are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently.

DarwinTunes: a social experiment

on

DarwinTunes bills itself as a “test tube for cultural evolution.” It’s an online experiment being run by researchers at Imperial College London. We often talk about the evolution of social media or cultural memes – but is that just a metaphor, or is it really evolution?

Generating 3D models from webcams

on Comments (2)

One highly inconvenient thing about working with virtual worlds or 3D content in general is: where do your 3D models come from (especially if you’re on a budget)? A talented but (inevitably) overworked 3D artist? An online catalog of variable quality and cost? Messing around yourself with tools like SketchUp or Blender? What if you want something very specific, very quickly? The MIR (Mixed and Immersive Realities) team here at FXPAL is very interested in these questions and has done some work in this area. Others are working on it too: here’s an elegant demo from Qi Pan at the University of Cambridge, showing the construction of a model with textures from a webcam image:

ARdevcamp: Augmented Reality unconference Dec. 5 in Mountain View, New York, Sydney…

on Comments (1)

We’re looking forward to participating in ARdevcamp the first weekend in December. It’s being organized in part by Damon Hernandez of the Web3D Consortium, Gene Becker of Lightning Labs, and Mike Liebhold of the Institute for the Future (among others – it’s an unconference, so come help organize!) So far, there are ~60 people signed up; I’m not sure what capacity will be, but I’d sign up soon if you’re interested. You can add your name on the interest list here.

From the wiki:

The first Augmented Reality Development Camp (AR DevCamp) will be held in the SF Bay Area December 5, 2009.

After nearly 20 years in the research labs, Augmented Reality is taking shape as one of the next major waves of Internet innovation, overlaying and infusing the physical world with digital media, information and experiences. We believe AR must be fundamentally open, interoperable, extensible, and accessible to all, so that it can create the kinds of opportunities for expressiveness, communication, business and social good that we enjoy on the web and Internet today. As one step toward this goal of an Open AR web, we are organizing AR DevCamp 1.0, a full day of technical sessions and hacking opportunities in an open format, unconference style.

AR DevCamp: a gathering of the mobile AR, 3D graphics and geospatial web tribes; an unconference:
# Timing: December 5th, 2009
# Location: Hacker Dojo in Mountain View, CA

Looks like there will be some simultaneous ARdevcamp events elsewhere as well – New York and Manchester events are confirmed; Sydney, Seoul, Brisbane, and New Zealand events possible but unconfirmed.

Mathematical and Musical Adventures

on Comments (2)

The next talk in the Bay Area Mathematical Adventures series is this Friday. Robert Bryant, the current director of MSRI, will speak on “Rolling and Tumbling—The idea of Holonomy.” It sounds like a fun talk; he’ll illustrate his talk with “everyday and some not-so-everyday toys.”

I’ve posted the slides from my Bay Area Mathematical Adventures talk last month on From Photographs to Models: The Mathematics of Image-Based Modeling. I blogged about that experience here. I had hoped to post a link to the video at the same time, but it isn’t ready yet. I never feel that a talk is fully captured from just the slides, especially one that was designed to be interactive. I will post a link to the video once it is up.

I’d be tempted to go to Bryant’s talk except that I’m singing that night. Two FXPAL folks, Bill van Melle and I, sing in the 40 voice Bay Choral Guild. We have concerts Fri, Sat, and Sun at various Bay Area locations. Come if you are in the area and would enjoy a concert of festive Baroque choral works performed by our excellent group together with an outstanding group of soloists and musicians!

Google Scholar is now legal

on

In 2001, when we were thinking about how to use e-books for legal research, we partnered with Lexis Nexis to study a moot court class in a law school. Without access to the documents that we obtained through Lexis, we would not have been able to engage the students and to explore potential designs for such devices.

But that was eight years ago. Today, we could resort to Google Scholar: A couple of days ago, Google announced on its blog that it will be including full text legal opinions from U.S. federal and state district, appellate and supreme courts in results returned by Google Scholar. In addition to each case, Google also returns citations of that case in other opinions. This service is unlikely to put West Publishers or Lexis Nexis out of business, but it does make it considerably easier for the average person (or researcher) to find these cases.

Choose Your Own Adventure

Historically, the Hypertext research community is an intertwingling (a Ted Nelson-logism) of three distinct strands — structural computing, interaction, and HT literature, which could be mapped, roughly, onto the engineers, the HCI folk, and the humanists. While engineering and HCI aspects were somewhat necessary for HT literature, the focus, by definition, has been on exploring the boundaries of electronic literature. In the end, I think, it’s good writing that makes hypertext literature interesting much more so than clever interaction. In fact, the electronic component is often not necessary at all: see If On a Winter’s Night a Traveler, for example.

But there is room for beauty in interaction as well. Thanks to Mark Bernstein of Eastgate, I came across a beautiful set of visualizations of narrative structure of CYOA, a series of hypertext books for children. Through a variety of charts and graphs like the one shown here, the author of these diagrams conveys the many alternate paths through a each story in the collection, and uses these visuals to compare, to analyze, and to appreciate the books. And don’t forget the animations, accessible through a link near the top of the page.

My retelling won’t do it justice; take a look for yourself, and think about these designs next time you’re building a slide deck.

Finally, since these stories are now available as Kindle editions, in principle, it would be possible to collect actual reading paths that readers take through the works, and subject them to the same analyses. What sorts of hypotheses about reading, personality, and interaction could we answer with such data?

Preliminary TOC for the IP&M Special Issue on Collaborative Info Seeking

on Comments (12)

We are nearing the end of editing the Special Issue of Information Processing & Management, and are proud to announce the papers that will be in the issue. The Special Issue was the result of the 1st collaborative search workshop we organized at JCDL 2008; the next workshop is coming up soon! We had many submissions on a variety of related topics, including field work and other reporting that characterized instances of collaboration in information seeking, evaluation and models of collaborative episodes, and a number of system and algorithm papers.

Print media and augmented reality

on

December’s issue of Esquire features augmented reality not only on its cover but a couple of places inside. This is not the first instance of AR on print media, of course, but it’s nicely done. I’d love to see this sort of thing make its way into scientific publishing eventually, for 3d and animated illustrations and data visualization. Right now authors can put digital content related to their work out on the web, but it’s an altogether different subjective experience when it’s integrated into the printed object (book, journal, etc.).

Here’s a video tour of the AR in the Esquire issue:

And comments from mashable:

“Print might be in trouble, but Esquire magazine won’t be going gently into that good night. The December issue of the magazine will feature augmented reality pages that will come alive when displayed in front of a webcam.

Augmented reality is a trend and phenomenon we’re starting to see more and more uses of across the web. In March, GE played with augmented reality while showing off its Smart Grid technology. Earlier this month, musician John Mayer released an augmented reality enhanced music video. The Disney.com iPhone app that was released earlier this week also utilizes some AR features.”
