Congratulations to LUCI grad students Sen Hirano, Jed Brubaker and LUCI faculty Don Patterson, and Gillian Hayes on having a paper conditionally accepted to UBICOMP 2013!

Detecting food type and cooking state with gas sensors during dry cooking

“In this paper, we describe the potential for using gas sensors to track food during the cooking process. Focusing on one cooking method–dry cooking–we collected gas emissions using a combination of 14 sensors during trials in which food was cooked to various degrees of doneness. Using decision tree classifiers, we were able to predict doneness for waffles and popcorn with 73% and 85% accuracy, respectively. We reflect on the potential reasons for this variation and the ways in which gas sensors might reliably be used in ubicomp applications to support cooking.”

Congratulations to former Informatics grad student, Nitin Shantharam, and Informatics faculty Donald Patterson (and DLR colleague Thomas Strang) on having their paper, “Interchange: Bidding for Green Lights” accepted to PerCom 2013.

“In urban environments great effort is directed toward alleviating traffic including the design and implementation of complex software and hardware infrastructure. We introduce the idea of an auction-based mechanism for resolving vehicle intersections using a multi-way group auction mechanism. We propose a supporting infrastructure that has promise for increasing performance and responsiveness to dynamic traffic conditions. We propose new metrics to evaluate intersections that attempt to capture a more human aspect of vehicular transportation. We demonstrate that Interchange intersections perform well in single and multi-grid configurations, are self-adapting and can perform better under a variety of traffic loads.”

Congratulations to Informatics faculty and researchers, Bill Tomlinson, Bonnie Nardi, Don Patterson and Six Silberman on having their paper, “Collapse Informatics and Practice: Theory, Method, and Design” accepted to a special issue of ToCHI focussed on ‘Sustainable HCI through Everyday Practices’

“What happens if efforts to achieve sustainability fail? Research in many fields argues that contemporary global industrial civilization will not persist indefinitely in its current form, and may, like many past human societies, eventually collapse. Arguments in environmental studies, anthropology, and other fields indicate that this transformation could begin within the next half-century. While imminent collapse is far from certain, it is prudent to consider now how to develop sociotechnical systems for use in these scenarios. We introduce the notion of collapse informatics—the study, design, and development of sociotechnical systems in the abundant present for use in a future of scarcity. We sketch the design space of collapse informatics and a variety of example projects. We ask how notions of practice—theorized as collective activity in the “here and now”—can shift to the future since collapse has yet to occur. ”

Gold to Gigabytes - October 6th, 2012

Exhibit Brochure

barbie is our neighbor

Department of Anthropology faculty, Bill Maurer, director of the Institute for Money, Technology and Financial Inclusion, with a team of curators, has put together a very interesting exhibit called “Gold to Gigabytes: The Past, Present, and Future of Money” It’s a sibling exhibit to one that is on display in The British Museum. Our’s is on display at the UCI Langson Library just after you walk in.

The opening of the exhibit is going on now. It is a really incredible score for our library and UCI! The LUCI lab participated in this exhibit in two ways: We provided a physical bitcoin model which you can see in the case. This wouldn’t have been possible without Prof. Hayes‘ foresight in purchasing a 3D printer and Ph.D. Student Sen Hirano’s expertise in making it work. We also provided a video loop of the first sequence of transactions in the bitcoin network graphically displayed.

Swing by the library and take a look!

Congratulations to LUCI faculty member Don Patterson on receiving the Artificial Intelligence journal Prominent Paper award. The AIJ Prominent Paper Award recognizes outstanding papers published not more than five years ago in the AI Journal that are exceptional in their significance and impact.

The award was given for:
Learning and inferring transportation routines
By Lin Liao, Donald J. Patterson, Dieter Fox, Henry Kautz
Volume 171, Issues 5-6, April 2007, Pages 311-331

“This paper introduces a hierarchical Markov model that can learn and infer a user’s daily movements through an urban community, and applies it in an application that helps cognitively-impaired people use public transportation safely. The paper takes a realistic and important problem, and solves it by developing technically sophisticated, state-of-the-art AI techniques, that have applicability well beyond the domain described in the paper. This work has had a significant impact on the area of modeling and learning with dynamic Bayesian networks, both in and outside of AI. As such, the award committee unanimously believes the paper is a worthy winner of the inaugural AIJ Prominent Paper Award.”

kinectable_pipe - July 6th, 2012

kinectable_pipe is a command-line utility that dumps user skeleton data from a Microsoft Kinect device to a standard Unix pipe.

Why?

Because Kinect programming is a pain in the neck, and by trivializing the device’s output into a simple text format, it becomes infinitely easier to digest in the scripting language of your choice.

This seems simple to the point of being almost useless

Yes, that’s the point. Do One Thing and Do It Well. There’s an accompanying rubygem that will add all the smart stuff like advanced gesture recognition, events, etc.

I tried it. It worked:

  • Time 0:00 ran down to lab to grab Kinect
  • Time 1:40 Kinect plugged into Mac
  • Time 6:00 Software installed
  • Time 7:00 Path problem fixed
  • Time 9:30 Data being collected
  • Time 30:00 Data formatted and posted

Interchange: An Analysis of Auction Mechanics for Intersections - June 18th, 2012

Congratulations to Nitin Shantharam who passed his M.S. advancement to candidacy exam with the paper:

“Interchange: An Analysis of Auction Mechanics for Intersections”

Abstract: In urban environments a large amount of effort is directed toward alleviating mo- tor vehicle congestion including the design and implementation of complex software and hardware infrastructure. We propose a conceptually simple infrastructure that has promise for increasing performance and responsiveness of intersections to dynamic traffic conditions. The proposed system uses an auction-based mechanism at intersections to alleviate traffic congestion. We discuss the reasoning and goals of implementing auction mechanics into intersections and set empirical expectations as to how such intersections should perform. Second, we compare our simulation of a traditional intersection and an auction-based intersection and propose metrics to track and evaluate such intersections. We demonstrate that auction-based intersections perform well in single and multi-grid configurations. Finally, we present our mesoscopic simulator capable of simulating real-world topographies and show that auction-based intersections show promise in more realistic systems as well.

Committee:

  1. Prof. Donald Patterson (chair)
  2. Prof. Bill Tomlinson
  3. Prof. Ramesh Jain

Great Job Nitin!

Gift Box: Including Social Objects in Internet of Things - April 6th, 2012

Congratulations to Vrishti Gulati who passed her M.S. advancement to candidacy exam today:

Title: Gift Box

Abstract: This paper highlights a research gap in the Internet of Things, i.e., the absence of particular categories of social objects that matter to non-technical everyday users. Social objects are existing physical objects that people bond with, are attached to, or that connect people to each other. We conducted a study, named Gift Box, to specifically look at the social aspects emerging within the Internet of Things (IoT). The study represents gifts, a specific category of social objects that connect people to each other, through pictures on a social media website. The study offers a simulated interaction with the Internet of Things, to identify social objects that matter to users. The study is a first step for users to include objects of their choice. Understanding user engagement and sociality supported within the IoT can lead to a more successfully accepted Internet of Things.

This paper has two contributions: Gift Box user study to identify social objects that matter to users, so that such objects can be included in the Internet of Things and a Technology spectrum for the Internet of Things to support consideration about the kind of objects, technology within the objects, and capability of user contribution to creation of the Internet of Things.

Committee:

  1. Dr. Donald Patterson (chair)
  2. Dr. Alfred Kobsa
  3. Dr. Melissa Mazmanian
  4. Dr. Bonnie Nardi
  5. Dr. Alladi Venkatesh

Great Job Vrishti!
