CHI 2010
Here are some of the CHI 2010 papers we like:

On cross-cultural HCI

Postcolonial computing: a lens on design and development
Lilly Irani, Janet Vertesi and Paul Dourish, Department of Informatics, University of California, Irvine;
Kavita Philip, Department of Women’s Studies, University of California, Irvine;
Rebecca E. Grinter, GVU Center and School of Interactive Computing College of Computing Georgia Institute of Technology

As our technologies travel to new cultural contexts and our designs and methods engage new constituencies, both our design and analytical practices face significant challenges. We offer postcolonial computing as an analytical orientation to better understand these challenges. This analytic orientation inspires four key shifts in our approach to HCI4D efforts: generative models of culture, development as a historical program, uneven economic relations, and cultural epistemologies. Then, through reconsideration of the practices of engagement, articulation and translation in other contexts, we offer designers and researchers ways of understanding use and design practice to respond to global connectivity and movement.

After access – challenges facing mobile-only Internet users in the developing world
Shikoh Gitau, Gary Marsden, Hasso Plattner ICT4D Research School, University of Cape Town, South Africa;
Jonathan Donner, Microsoft Research India

This study reports results of an ethnographic action research study, exploring mobile-centric internet use. Over the course of 13 weeks, eight women, each a member of a livelihoods collective in urban Cape Town, South Africa, received training to make use of the data (internet) features on the phones they already owned. None of the women had previous exposure to PCs or the internet. Activities focused on social networking, entertainment, information search, and, in particular, job searches. Results of the exercise reveal both the promise of, and barriers to, mobile internet use by a potentially large community of first-time, mobile-centric users. Discussion focuses on the importance of self-expression and identity management in the refinement of online and offline presences, and considers these forces relative to issues of gender and socioeconomic status.

On micro-blogging and social networking

Tune in, tweet on, twit out: information snacking on Twitter
Elizabeth Churchill of the Internet Experiences Group of Yahoo! Research;
Andrew L. Brooks of the School of Information University of California, Berkeley

Microblogging via services such as Twitter is changing the way we share and access information. We report findings from three studies that explored everyday information seeking and sharing activities: local news consumption, shopping, and recommendation making by concierges in the hotel industry. Although our focus was not Twitter per se, the service is increasingly seen as having value for solving specific situational information needs. Through examples we illustrate how Twitter has evolved from a service for sharing personal status messages to being used as a source for pursuing one-off, disposable information requests.

Media, conversations, and shadows
David A. Shamma, Lyndon Kennedy, and Elizabeth F. Churchill of the Internet Experiences Group of Yahoo! Research

This article proposes that microblogged messages that relate to a live event can be examined as indirect annotation on a media object that might not exist. From a collection of Twitter posts around two political events, we have begun to discover techniques for identifying how microblog posts relate to the matching media event. Further, we identify the relationship between the media event itself and the conversational shadow cast from the online community.

Sensemaking with tweeting: exploiting microblogging for knowledge workers
Bongwon Suh, Lichan Hong, Gregorio Convertino, Ed H. Chi, Palo Alto Research Center;
Michael Bernstein, MIT Computer Science and Artificial Intelligence Laboratory

Just because the rules surrounding microblogging services are simple does not mean that tools support for them should be simple too. Microblogging generates volumes of interesting social content, but there is a lack of frameworks and tools that allow us to exploit such information and enhance knowledge workers’ sensemaking. Beyond adoption, we believe that new promising research directions on microblogging include designing and evaluating tools that extract and exploit social information. In this paper, we discuss a number of ways to exploit microblogging in support of two recurrent sensemaking tasks: (1) when a user is seeking information (information foraging and active exploration) and (2) when information is delivered to the user (awareness and passive monitoring).

What do people ask their social networks, and why? A survey study of status message Q&A behavior
Meredith Ringel Morris, Microsoft Research Redmond;
Jaime Teevan, Microsoft Research Redmond;
Katrina Panovich, Massachusetts Institute of Technology.

People often turn to their friends, families, and colleagues when they have questions. The recent, rapid rise of online social networking tools has made doing this on a large scale easy and efficient. In this paper we explore the phenomenon of using social network status messages to ask questions. We conducted a survey of 624 people, asking them to share the questions they have asked and answered of their online social networks. We present detailed data on the frequency of this type of question asking, the types of questions asked, and respondents’ motivations for asking their social networks rather than using more traditional search tools like Web search engines. We report on the perceived speed and quality of the answers received, as well as what motivates people to respond to questions seen in their friends‟ status messages. We then discuss the implications of our findings for the design of next-generation search tools.

On energy use

Home, habits, and energy: examining domestic interactions and energy consumption
James Pierce, Computer Science Laboratory Palo Alto Research Center and HCI Institute Carnegie Mellon University;
Diane J. Schiano, Computer Science Laboratory Palo Alto Research Center and SAMA Group Yahoo!, Inc.;
Eric Paulos, HCI Institute Carnegie Mellon University

This paper presents findings from a qualitative study of people’s everyday interactions with energy-consuming products and systems in the home. Initial results from a large online survey are also considered. This research focuses not only on “conservation behavior” but importantly investigates interactions with technology that may be characterized as “normal consumption” or “over-consumption.” A novel vocabulary for analyzing and designing energy-conserving interactions is proposed based on our findings, including: cutting, trimming, switching, upgrading, and shifting. Using the proposed vocabulary, and informed by theoretical developments from various literatures, this paper demonstrates ways in which everyday interactions with technology in the home are performed without conscious consideration of energy consumption but rather are unconscious, habitual, and irrational. Implications for the design of energy-conserving interactions with technology and broader challenges for HCI research are proposed.

Studying always-on electricity feedback in the home
Yann Riche, Riche Design Seattle;
Jonathan Dodge and Ronald A. Metoyer, Oregon State University, School of EECS

The recent emphasis on sustainability has made consumers more aware of their responsibility for saving resources, in particular, electricity. Consumers can better understand how to save electricity by gaining awareness of their consumption beyond the typical monthly bill. We conducted a study to understand consumers’ awareness of energy consumption in the home and to determine their requirements for an interactive, always-on interface for exploring data to gain awareness of home energy consumption. In this paper, we describe a three-stage approach to supporting electricity conservation routines: raise awareness, inform complex changes, and maintain sustainable routines. We then present the findings from our study to support design implications for energy consumption feedback interfaces.

The design of eco-feedback technology
Jon Froehlich and James Landay, Computer Science and Engineering, DUB Institute, University of Washington;
Leah Findlater, The Information School, DUB Institute, University of Washington

Eco-feedback technology provides feedback on individual or group behaviors with a goal of reducing environmental impact. The history of eco-feedback extends back more than 40 years to the origins of environmental psychology. Despite its stated purpose, few HCI eco-feedback studies have attempted to measure behavior change. This leads to two overarching questions: (1) what can HCI learn from environmental psychology and (2) what role should HCI have in designing and evaluating eco-feedback technology? To help answer these questions, this paper conducts a comparative survey of eco-feedback technology, including 89 papers from environmental psychology and 44 papers from the HCI and UbiComp literature. We also provide an overview of predominant models of proenvironmental behaviors and a summary of key motivation techniques to promote this behavior.
