Back from a one week break!

Enabling A "Killer Ecology" in Mobile Computing
Joel Brandt (Stanford University)

Friday, May 11th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley
http://upcoming.yahoo.com/event/184954/

ABSTRACT:
Already there are 2.5 billion mobile phones in active use today, in comparison with an estimated 1 billion PCs. Yet the bulk of these mobile phones are only used as communication devices, not as computing devices. Many individuals and corporations are investing a large amount of time and money to build the killer applications that will realize this latent potential. We suggest, however, that the true potential of mobile computing will be achieved not through a few killer applications, but through a killer ecology of many small, niche applications that are highly tailored to specific users' needs.

In this talk, I will discuss three topics central to enabling this killer ecology: what, who, and how. First, I will approach the topic of what the space of desired mobile applications looks like. I will present a classification of the design space of mobile computing applications, born out of a need-finding study conducted with 23 participants. From here, I will discuss who may be creating mobile applications in the future, and how this affects our design of tools to support this development. This discussion will be supported by a presentation of Lash-Ups, a lightweight toolkit we have developed to enable programming of location-aware mobile applications by amateur developers. Finally, I will discuss how these applications should be built from an interaction design perspective. Specifically, I will present five issues central to the successful design of interactions for mobile and attention-limited tasks, identified through our own work and through interviews with five professional designers.

BIO:
Joel Brandt is a second-year Ph.D. student working with Professor Scott Klemmer in the Stanford Human-Computer Interaction Group. His research focuses on design and development tools for mobile applications. More specifically, he is interested in understanding how to create tools that empower amateur programmers. Before coming to Stanford, he completed his B.S. and M.S. work at Washington University in St. Louis.

http://upcoming.org/event/149257/

Abstract:
We constructed EcoPod, a PDA-based tool that helps skilled amateurs identify plants and animals out in the field. The tool is intended for biodiversity census activities. EcoPod asks its user questions about the organism that it is deployed to help identify. Users may attach evidence to each answer, and they may register uncertainty with their decision. I will describe EcoPod and then move to a specific problem we needed to solve in its design: The tool should ask as few questions as possible so as to optimize the user experience. We use well-known decision tree and information gain theory towards this optimization. I will sketch this approach and show how we use historic species observation data to optimize typical usage patterns.

Biography:
Dr. Andreas Paepcke is a Senior Research Scientist and director of the Digital Library and BioACT Projects at Stanford University. His interests include user interfaces for small devices, novel Web search facilities, and browsing facilities for digital artifacts that are difficult to index. With his group of students he has designed and implemented WebBase, an experimental storage and high speed dissemination system for Web contents. His work on small devices has focused on novel methods for summarizing and transforming Web pages, and on browsing images on small displays. He serves on the editorial board of the ACM TWEB journal. Dr. Paepcke received BS and MS degrees in applied mathematics from Harvard University, and a Ph.D. in Computer Science from the University of Karlsruhe, Germany. Previously, he worked as a researcher at Hewlett-Packard Laboratory, and as a research consultant at Xerox PARC.

Over-Exposed Privacy Patterns and Considerations in Online and Mobile Photo Sharing

Abstract:
As sharing personal media online becomes easier and widely spread, newprivacy concerns emerge – especially when the persistent nature of themedia and associated context reveals details about the physical andsocial context in which the media items were created. In afirst-of-its-kind study, we use context-aware camerephone devices toexamine privacy decisions in mobile and online photo sharing. Throughdata analysis on a corpus of privacy decisions and associated contextdata from a real-world system, we identify relationships betweenlocation of photo capture and photo privacy settings. Our data analysisleads to further questions which we investigate through a set ofinterviews with 15 users. The interviews reveal common themes inprivacy considerations: security, social disclosure, identity andconvenience. Finally, we highlight several implications andopportunities for design of media sharing applications, including usingpast privacy patterns to prevent oversights and errors.

Why We Tag: Motivations for Annotation in Mobile and Online Media

Abstract:
Why do people tag? Users have mostly avoided annotating media such asphotos – both in desktop and mobile environments – despite the manypotential uses for annotations, including recall and retrieval. Weinvestigate the incentives for annotation in Flickr, a popularweb-based photo-sharing system, and ZoneTag, a cameraphone photocapture and annotation tool that uploads images to Flickr. In Flickr,annotation (as textual tags) serves both personal and social purposes,increasing incentives for tagging and resulting in a relatively highnumber of annotations. ZoneTag, in turn, makes it easier to tagcameraphone photos that are uploaded to Flickr by allowing annotationand suggesting relevant tags immediately after capture. A qualitativestudy of ZoneTag/Flickr users exposed various tagging patterns andemerging motivations for photo annotation. We offer a taxonomy ofmotivations for annotation in this system along two dimensions(sociality and function), and explore the various factors that peopleconsider when tagging their photos. Our findings suggest implicationsfor the design of digital photo organization and sharing applications,as well as other applications that incorporate user-based annotation.

Casual Worlds and Player-Generated Content

Friday, April 6th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley

ABSTRACT
Whirled, the new project currently under development at Three Rings Design, is a web-based massively multiplayer game world. Like previous Three Rings projects, it centers around a fun environment where people socialize while playing engaging multiplayer games.

An exciting new element is the emphasis on creative self-expression: in addition to playing games and socialization, players will be able to sculpt their world the way they like it, including changing its topology, appearance, and activities. Game economy is also being drastically altered, as players of all skill levels will be empowered to create and sell their own party games, furniture, avatars, rooms, and remix other users' creations, using our in-game tools.

The talk will introduce the work in progress, and present some of the software engineering and social engineering elements that make this kind of a virtual whirled possible.

BIOGRAPHY
Dr. Robert Zubek is a game developer at Three Rings Design, a San-Francisco studio that builds web-based multiplayer games. Before Three Rings, he worked at Electronic Arts / Maxis. Robert holds a Ph.D. in computer science from Northwestern University, where he developed artificial intelligence approaches for computer games and autonomous robots.

Qingfeng Huang (PARC)
Spatiotemporal Information Dissemination and Beyond

Friday, March 30th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley

ABSTRACT
My exploration of spatial and temporal information dissemination started form the observation that a piece of information could have different value at different location and time, and just-in-time information delivery can be essential in achieving information dissemination efficiency. The exploration resulted with a few new information dissemination strategies that gear towards distributed applications that handle location and time sensitive data. A unified theme among the approaches is making space and time the first class citizen in networking and information dissemination. In this talk I will start from discussion of my past work in this direction in mobile and sensor network context, and discuss potential ramifications beyond the networking context (if time permits).

BIOGRAPHY
Qingfeng Huang received his D.Sc. degree in Computer Science from Washington University in St. Louis in 2003. He also holds A.M. degree in Physics. Dr. Huang has been a research scientist at the Palo Alto Research Center (PARC) since 2003 and filed more than 20 patents in the last two years. He has also published more than 35 academic papers in areas including software engineering, context-aware and mobile computing, sensor networks, intelligent transportation systems, neuroscience, and quantum physics. His current research interests include algorithms and middleware for transportation networks and sensor actuator networks, tools enabling knowledge sharing and harvesting in networks (e.g. for healthcare and education), non-invasive brain-interface technology and personal sensing, and mechanisms that facilitate innovation.

Ambient Interfaces: What Pervasive Computing Can Learn from Architecture

Friday, March 16th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/153094

ABSTRACT
As "the web" migrates from desktops and laptops, slowly forming a landscape of pervasive computing, new interaction design challenges emerge that invite (even demand) further integrations of disciplinary approaches. The (social) success of pervasive computing will depend on a convergence of information science, sociology and architecture. Through such an approach, different programs –computational programs, habitational programs, and architectural programs- mutually support and volatize each other to produce active space. Pervasive computing will engender different agendas for interaction. Instead of pushing messages or focusing data-filing, the critical challenge is to design something more foundational, more literally grounded: a complex of ambient interfaces. In essence, pervasive computing will share and augment not only the site on which architecture sits, but also the job that architecture does; that is, to provide an active frame for specific social activities. The web is a "lean forward" medium. It is blindingly fast. It is kinetic, visual, and increasingly so. Whereas, architecture is a "distracted medium." It is slow and sensual. It is meta-contextual. One is a loud foreground. The other is a quiet background. However, in important ways pervasive computation may perform more like today's architecture than today's web. It too will be more a frame for activity than a centralizing focus of visual attention. Furthermore, many contemporary architects have enthusiastically embraced the design potential of pervasive computing. For them, "data" is a another material –like steel or glass—with which to realize a compelling spatial system. It is perhaps to their stages that information design will turn. If so, how can these disciplines not only co-exist, but reinforce each other? This talk will consider these problematics in relation to:

--Contemporary theories of architectural program and architectural interfaces
--Examples and critique of architectural integrations of computation as a spatial medium
--Implications of architectural thinking for digital media design
--Implications of ambient/architectural digital media for Yahoo!

I will show and discuss related projects by several design studios, including, Art+Com, OMA/AMO, Diller + Scofidio, Thomas Leeser, Antenna, Imaginary Forces, Christian Moeller, Asymptote, Francois Roche, REX, Rafael Lozano-Hemmer, Tronic, UN Studio, MVRDV, Dunne+Raby, and others.

Paper-Based and Mobile Multimedia Document Browsing Techniques

Friday, March 9th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/155011

ABSTRACT
In contrast to conventional two-dimensional text-based documents that are easily browsed in limited amounts of time, video and audio files are difficult to skim because they are inherently one-dimensional. We've attempted to overcome this limitation with an approach we call Video Paper that summarizes multimedia recordings as documents that show what's in a recording and provide random access to the multimedia data. Several formats for the documents will be discussed including a multimedia newspaper we call Media Times. In addition, our experience using tools for creating Video Paper documents will be presented including a PC desktop application and a digital photocopier. A recently developed bar code-based retrieval interface for Video Paper will be demonstrated on a Windows Mobile Treo.

A method called Multimedia Thumbnails for viewing high resolution multi-page documents on devices with small displays will also be presented. In this technique, we convert a text-based document into an audiovisual clip of fixed duration that can be viewed on a handheld device. The visual channel presents important visual document parts such as titles and figures by zooming and panning. The audio channel presents synthesized audible document information, such as keywords and figure captions.

The work described in this presentation is joint with Jamey Graham and Berna Erol.

Designing Civic Software

http://upcoming.org/event/149223


------------------------Abstract ------------------------
We are witnessing the emergence of decentralized groups without formal organizations emerging to solve complex social problems and take action in the world together. In groups people can accomplish what they cannot do alone. New visual and social technologies are making it possible for people not only to create community but also to wield power and create rules to govern their own affairs. This presentation will focus on technology and the opportunity for collective action, particularly on the emerging frameworks -- both technological and legal -- for "collective visualization" which will profoundly reshape the ability of people to make decisions, own and dispose of assets, organize, protest, deliberate, dissent and resolve disputes together. By looking at several examples, including the design of "Peer to Patent" and the Visual Company (http://dotank.nyls.edu ). We will discuss the process of digital institution design that melds legal code and software code to address how institutions respond to the growth of networks. In so doing, we will not only address how technology is used in our democracy but how it might change what we ultimately come to define as democracy.

-----------------------Abstract------------------------------------
Recognition algorithms in computer vision have come a long way in the
last 10 years. I will describe some of the successes and failures for
recognition algorithms, concentrating on some of our work at Berkeley
including:

- recognizing objects by matching shapes in images
- recognizing actions in video
- recognizing scenes
- indexing large collections of video by content

The talk will cover what might be the short-term future of recognition
algorithms and applications.

This week in Yahoo Research Berkeley Brain Jam:
Tamara Berg (Yahoo! Research Berkeley)
Exploiting the Link Between Words and Pictures

Friday, February 23rd, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/152244


------------------------Abstract ------------------------
There are billions of photographs with associated text available on the web. Some common areas where images and words are naturally linked include: web pages, captioned photographs, and video with speech or closed captioning. The central challenge that needs to be solved in order to organize these collections effectively is how to extract images in which specified objects are depicted from large pools of pictures with noisy text. This is a very difficult problem because the relationship between words associated with an image and objects depicted within the image is often complex.  My work has demonstrated that for many situations these collections can be mined successfully. I will talk about three projects that I have worked on in this area: Automatically labeling faces in news photographs, classifying images from the web, and ranking iconic images from consumer photo collections. All papers, created datasets, and demos are available on my webpage at: http://www.cs.berkeley.edu/~millert/.

This week in Yahoo Research Berkeley Brain Jam:
Cathy Marshall (Microsoft Research)
"It's like a fire. You just have to move on": Toward adaptive services for personal archiving

Friday, February 9th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/143021


------------------------Abstract ------------------------
Most of us engage in magical thinking when it comes to the long term fate of our personal digital stuff. This magical thinking may manifest itself in several ways: technological optimism ("I know there'll be a solution when I want to look at those files again"), radical ephemeralism ("It's like a fire: you just have to move on"), or simply a gap between principals and practice ("I should move my novel off of that zip disk, but I'm too busy right now"). At this point, benign neglect seems to be the best we can hope for. For the last few years, we've tried to understand the current state of personal digital archiving in practice with the aim of designing services for the long-term storage, preservation, and access of digital belongings. Our studies have not only confirmed that experienced home computer users have accumulated a substantial amount of digital stuff that they care about, but also that they have already lost irreplaceable artifacts such as photos, creative efforts, and important records. Although informants report digital safekeeping strategies, they are neither able to implement them consistently, nor will these strategies address the real problems associated with archiving. I will discuss four central themes of personal digital archiving and some additional challenges introduced by home computing environments. I'll also talk about how these themes relate to emerging institutional archiving technologies, best practices, and information policies. This talk will reveal how far we've gotten on our quixotic mission and why we won't give up, even in the face of adversity, table-pounding, and social ostracism.

-----------------------Bio-----------------------------------------
Cathy Marshall is a Senior Researcher at Microsoft Corporation. Her research on personal digital libraries lies in the disciplinary interstices of computer science, information science, and the humanities. She was a long-time member of the research staff at Xerox PARC and is an affiliate of the Center for the Study of Digital Libraries at Texas A&M University. She has delivered keynote addresses at the WWW and Hypertext Conferences as well as at CNI and other library and information science venues. She has served as Program Chair for the IEEE/ACM Joint Conference on Digital Libraries (twice) and for the ACM Hypertext Conference.

Open House
Friday, February 2, 2007
3:00 PM - 5:00 PM
Yahoo! Research Berkeley
1950 University Ave, Suite 200
Berkeley, California 94704

We are hiring interns for Spring and Summer of 2007. To start it off, we are opening our doors and inviting you (and hopefully you are an aspiring research intern) to come on down and check out our digs in Berkeley. We'll be demo-ing our latest research prototypes, presenting our research vision, talking to you about projects and finding out a bit about you as well. Our current interns will be on-hand to give you the real dirt about how cool it is to work here. Yeah, really. And of course, what open house is complete without a prize and free stuff? An iPod nano will be raffled away, where your resume is your raffle ticket. Swag, refreshments and drinks will be served. More details.

Sorry for the late notice. Our speaker is home with the flu, and we
feel like it's better for him (and you) that he'd stay at home.

Other entertainment will be provided in a form of a pre-recorded talk
(should be interesting) if you do show up. Social Jam with snacks and
beer will still happen at 4pm.

Don't forget next week, open house for those of you interested in
summer internships, and the rest of what's coming:

Spatiotemporal Information Dissemination and Beyond
 
My exploration of spatial and temporal information dissemination started form the observation that a piece of information could have different value at different location and time, and just-in-time information delivery can be essential in achieving information dissemination efficiency.   The exploration resulted with a few new information dissemination strategies that gear towards distributed applications that handle location and time sensitive data.   A unified theme among the approaches is making space and time the first class citizen in networking and information dissemination.  In this talk I will start from discussion of my past work in this direction in mobile and sensor network context,  and discuss potential ramifications beyond the networking context (if time permits).

-----------------------Bio-----------------------------------------
Qingfeng Huang received his D.Sc. degree in Computer Science from Washington University in St. Louis in 2003.   He also holds A.M. degree in Physics. Dr. Huang has been a research scientist at the Palo Alto Research Center (PARC) since 2003 and filed more than 20 patents in the last two years. He has also published more than 35 academic papers in areas including software engineering, context-aware and mobile computing, sensor networks, intelligent transportation systems, neuroscience, and quantum physics.  His current research interests include algorithms and middleware for transportation networks and sensor actuator networks, tools enabling knowledge sharing and harvesting in networks (e.g. for healthcare and education), non-invasive brain-interface technology and personal sensing, and mechanisms that facilitate innovation.

Scott Golder (HP Labs)
Digitizing Friendship: Learning from and about Massive Online Social Networks

Friday, Jan 19th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/138044/

Abstract:
Studying an online community may seem easy; plentiful server logs and databases make collecting their data almost simple. However, it's not so clear as that; these digital footprints represent only a thin slice of users' lives, making contextualizing and interpreting such data subtly challenging. In this talk, I present results from a study of the behavior of over 4 million users of the Facebook, a popular online social network. The results include interesting temporal patterns and insight into college students' lives, and raise questions about what it means to be a friend in a world where digital tools are woven into the fabric of our social lives. Generalizing from this study, I explore the value and tradeoffs of quantitatively analyzing online communities, and consider ways to more richly characterize individuals' and groups' online social lives.

Bio:
Scott Golder is a researcher in the Information Dynamics Lab at HP Labs. He studies online communities, social networks and collaborative systems and enjoys analyzing such environments as well as designing novel interfaces for them. His previous and ongoing work includes studies of del.icio.us, Facebook, Usenet, email and online gambling.

This week in Yahoo Research Berkeley Brain Jam:
Jon Foote
Analyzing Music and Audio by Self-Similarity

Friday, Jan 12th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/133461/

Abstract:
I will present ways to analyze music and audio based on self-resemblance, using a "similarity matrix" representation inter-frame spectral similarity. Besides yielding an engaging visualization of musical structure, this approach can be used to segment and index audio by content. I will present the fundamental ideas, musical examples, and some interesting applications and offshoots, including the "beat spectrum," a novel way to characterize musical rhythm. I will also present a system for retrieving music by rhythmic similarity, and discuss applications such as audio abstracting and automatic podcast indexing. If time permits I will present some "minute madness" of other work such as VideoBots?, FlyAbout, and some current speculative projects.

Bio:
Jonathan T. Foote was born in 1963 in Hollywood. He attended public schools in Santa Monica, California, somehow without learning how to surf. He received a BS (Electrical Engineering) degree in 1985 and a ME (Electrical) degree in 1986, both from Cornell University. From 1986 to 1988 he worked as a development engineer for Teradyne, Inc. in Boston, Massachusetts. In 1993 he received a Ph.D. in Electrical Engineering from Brown University, where he also received a Brown Presidential Teaching Award and an Outstanding Research Award from the Brown University Chapter of Sigma Xi. He did postdoctoral research at Cambridge University in the United Kingdom from 1993 to 1996, and was a 1997 Fulbright Fellow at the Institute of Systems Science (now A*STAR) in Singapore. From 1997 to 2005 he was a Senior Research Scientist at FX Palo Alto Laboratory, Inc. Currently he is a freelance consultant, as well as working on a manuscript and several speculative projects. Dr. Foote's research interests include speech recognition, audio analysis and retrieval, multimedia signal processing, and panoramic video. Dr. Foote has published more than 60 papers in these areas and has received Best Paper Awards at the ACM Multimedia and ACM SIGIR international conferences. Dr. Foote has been awarded eighteen US patents and has many more pending. He is also active in the arts, and enjoys not surfing in his free time.

It's 2007, good time to resume our weekly seminar! There are some exciting speakers lined up for you this year, stay tuned. Before this weeks announcement, I would like to point out that we are currently actively hiring interns (algorithms, systems, design and more) for this term as well as the summer. Drop me a line if interested, or see more on our blog at http://whyrb.com .

This week in Yahoo Research Berkeley Brain Jam:

Stephen W Smoliar
A Socio-Technical Approach to Content Mining

Friday, Jan 5th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/133460/

Abstract:
Content mining technology is based on the ability to identify andrecognize PATTERNS in large information repositories. Whether itinvolves data, metadata, or a combination of the two, the concept of"pattern" is a mathematical one; and it is because of its mathematicalnature that it can be readily manipulated by powerful software.Nevertheless, this is a dangerously limited interpretation of theconcept of "pattern," which can only impede efforts to engage softwareto facilitate the management of those repositories, whether theyconstitute a digital library or someone's favorite collection ofphotographs. If we wish to develop more powerful software, we mustbegin by acknowledging that patterns are not strictly OBJECTIVE (andthus susceptible to mathematical modeling) but also SUBJECTIVE andSOCIAL. As SUBJECTIVE phenomena, patterns are FLUID, their treatment oftime is qualitatively different from that of space, and they deal notjust with ARTIFACTS but also with the ACTS OF MAKING those artifacts.As SOCIAL phenomena, patterns are CONSTRUCTED THROUGH INTERPERSONALCOMMUNICATIVE ACTS. Consequently, effective content mining demandsanalytic techniques that embrace the subjective and social worlds aswell as the objective world of mathematics. While this constitutes anintimidating challenge to software development, it will be demonstratedthat socio-technical systems in areas such as knowledge management canprovide guidelines for taking a similar approach to content mining.

Bio:
Stephen William Smoliar obtained his PhD in Applied Mathematics and hisBSc in Mathematics from MIT. He has taught Computer Science at both theTechnion, in Israel, and the University of Pennsylvania. He has workedon problems involving specification of distributed systems at GeneralResearch Corporation and has investigated expert systems development atboth Schlumberger and the Information Sciences Institute (University ofSouthern California). Dr. Smoliar also has extensive background inmusic, having composed 36 works between 1969 and 1975, and is a formermember of the Society for Music Theory. His main areas of researchinterest are in knowledge representation, perceptual categorization,and cognitive models. From May of 1991 until August of 1994, he led aproject on video classification at the Institute of Systems Science atthe National University of Singapore. From August of 1995 until May of1999, he managed research programs in Multimedia and Communication andCollaboration at the FX Palo Alto Research Laboratory, after which heserved as Knowledge Solutions Coordinator until May of 2004.

WayMarkr: wearable mobile devices, memory prosthesis, and information visualization

Friday, Dec 8th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.
http://upcoming.org/event/131675

Abstract:
The WayMarkr system developed by Michael Bukhin and Michael DelGaudioturns a mobile phone into a self-documenting wearable device withvirtually unlimited disk space. WayMarkr uses a mobile device's camerato take continuous photographs from the vantage point of the wearer.Photographs are immediately uploaded to a data warehouse, along withmetadata and optional location information, enabling users to neverhave to worry about storage capacity on the phone. The ubiquity ofmobile devices makes WayMarkr unobtrusive, and the first image basedMemex device widely available to the general public. Because thecollected photographs are continuous the sequence of images creates apersonal narrative. Captured photographic narratives give usersperspective, insight, and alternative access to memory recollection.WayMarkr has potential use wherever documentation and participation areboth necessary. For example, as an ethnographic research tool, WayMarkrcould seamlessly document a participant's behavior. For this talk, wewill discuss the concept and technology behind WayMarkr. We will coverprior continuous documentation efforts and the innovation that WayMarkrbrings to the field. We will explain the WayMarkr website(waymarkr.com), the current interface for viewing WayMarkr content andpropose our future plans for data visualization and contentinterpretation.

This week in Yahoo! Research Berkeley's Brain Jam:

Elizabeth Churchill (Y! Research)
From media spaces to emplaced media

Friday, Dec 1st, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.

Abstract:
This talk centres on the linking of digital and physical places using interactive digital bulletin boards. I will introduce a number of installations allow community members to post or "place" digital community content. These boards not only link different geographic and social settings, but also provide a bridge between online community activity and activity in "offlne" physical places. I will discuss the grounding for the work, describe a couple of the installations and offer some observations on the future of emplaced community media.

**** Notice that Y!RB Brain Jam will take place on TUESDAY this week due to Thanksgiving ****

This week in Yahoo! Research Berkeley's Brain Jam:

Henry Chesbrough (UCB)
Open Business Models

Tue, Nov 21th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.

Abstract:
Professor Chesbrough will discuss his new book, Open Business Models (Harvard Business School Press, 2006). Companies need to do more than open up their innovation processes to sustain innovation. They need to open up their business models as well. The talk will explore the factors that inhibit experimentation with alternative business models, and point out some new practices that enable greater experimentation.

This week in Yahoo! Research Berkeley's Brain Jam:

Tye Rattenbury (UC Berkeley, Y!RB)
An Activity Based Approach to Context-Aware Computing
Friday, Nov 17th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.

Abstract:
As computing devices increase in number and functionality they have the potential to support more diverse and nuanced aspects of human life. The pressing issue is how to appropriately design these devices and their controls. Basic constraints on resources will inevitably require these devices to have light-weight controls and to operate proactively (at least in part). In this talk, I will present our approach to this design problem in the domain of computer-based information work (e.g. technology based research, audit consulting services, etc). The basic argument of this approach is that "appropriate", in terms of control and pro-active operation, is a term that can only be resolved with a sufficient grasp of "context". In deference to many contemporary social theories, we define context as an emergent quality of human activity. Accordingly, the method we use for identifying context relies on pattern mining over event logs of human behavior (specifically over logs of user-initiated events on the computer). To evaluate this approach for identifying context, we return to the motivating design issue – basically the approach has merit if we can design a more useful device based on it. I will describe an application we have developed that uses this pattern mining approach to detect relevant information items (documents, web pages, contacts) in real-time.

This is joint work with Professor John Canny at UC Berkeley.

Bjoern Hartmann (Stanford)
Prototypes and Mash-Ups: Tool Support for Rapid Off-the-Desktop Interaction Design
Friday, Nov 10th, 3pm
Yahoo! Research Berkeley
1950 University Ave., Berkeley.

Abstract:
In this talk, I will first present a brief overview of our work on prototyping tools for physical computing. d.tools, winner of the 2006 UIST best paper award, is a toolkit for prototyping information appliances that offers integrated support for design, test, and analysis. Deploying d.tools showed that designers and students wanted to interface their d.tools prototypes to other commercially available software and hardware. This motivates our current research on ubicomp mash-ups, which we define broadly as "combinations of existing technologies, glued together to achieve new functionality." I will describe a recent interview study with professional and hobbyist "mashers" from three different design disciplines: web 2.0 programmers, toy inventors, and designers of interactive ubicomp systems. I will present examples of how real world projects are built by screen scraping, reappropriating consumer electronics and "Frankensteining" software and hardware artifacts together. I will then distill some themes in opportunistic design and speculate about opportunities for HCI tool research in this space.

Bio:
Björn Hartmann is a PhD candidate in Computer Science at Stanford University, working in the Human Computer Interaction group with Prof. Scott Klemmer. He received a BA in Communication, a BSE in Digital Media Design, and an MSE in Computer and Information Science from the University of Pennsylvania in 2002. Before coming to Stanford he had a successful career as an electronic musician in Europe. His current research focuses on prototyping tools for physical and ubiquitous computing.
