André, Paul, Bernstein, Michael and Luther, Kurt (2012): Who gives a tweet?: evaluating microblog content value. In: Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 471-474. Available online

While microblog readers have a wide variety of reactions to the content they see, studies have tended to focus on extremes such as retweeting and unfollowing. To understand the broad continuum of reactions in-between, which are typically not shared publicly, we designed a website that collected the first large corpus of follower ratings on Twitter updates. Using our dataset of over 43,000 voluntary ratings, we find that nearly 36% of the rated tweets are worth reading, 25% are not, and 39% are middling. These results suggest that users tolerate a large amount of less-desired content in their feeds. We find that users value information sharing and random thoughts above me-oriented or presence updates. We also offer insight into evolving social norms, such as lack of context and misuse of @mentions and hashtags. We discuss implications for emerging practice and tool design.

Kittur, Aniket, Khamkar, Susheel, André, Paul and Kraut, Robert E. (2012): CrowdWeaver: visually managing complex crowd work. In: Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 1033-1036. Available online

Though toolkits exist to create complex crowdsourced workflows, there is limited support for management of those workflows. Managing crowd workers and tasks requires significant iteration and experimentation on task instructions, rewards, and flows. We present CrowdWeaver, a system to visually manage complex crowd work. The system supports the creation and reuse of crowdsourcing and computational tasks into integrated task flows, manages the flow of data between tasks, and allows tracking and notification of task progress, with support for real-time modification. We describe the system and demonstrate its utility through case studies and user feedback.

André, Paul, Schraefel, M. C., Dix, Alan and White, Ryen W. (2011): Expressing well-being online: towards self-reflection and social awareness. In: Proceedings of the 2011 iConference 2011. pp. 114-121. Available online

Medicine, psychology and quality of life literature all point to the importance of not just asking 'how are you?', but assessing and being aware of self and others' well-being. Social networking has been shown to have a variety of uses and benefits, but does not currently offer explicit expression of a well-being state. We developed and deployed Healthii, a social networking tool to convey well-being using a set of pre-defined discrete categories. We sought to understand how communicating this in a lightweight fashion may be used and valued. Using a hybrid methodology, over five weeks ten participants used the tool on Facebook, Twitter, or on the desktop, and in group meetings discussed the affect and effect of the tool, before a final individual survey. The trial showed that participants used and valued status expression for its support to convey state, and for self-reflection and group awareness. We discuss these findings as well as future opportunities for awareness visualization and automatic data integration.

André, Paul, schraefel, m.c., Dix, Alan J. and White, Ryen W. (2010): Experience in social affective applications: methodologies and case study. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 2755-2764. Available online

New forms of social affective applications are emerging, bringing with them challenges in design and evaluation. We report on one such application, conveying well-being for both personal and group benefit, and consider why existing methodologies may not be suitable, before explaining and analyzing our proposed approach. We discuss our experience of using and writing about the methodology, in order to invite discussion about its suitability in particular, as well as the more general need for methodologies to examine experience and affect in social, connected situations. As these fields continue to interact, we hope that these discussions serve to aid in studying and learning from these types of application.

Kleek, Max Van, Moore, Brennan, Karger, David R., André, Paul and schraefel, m.c. (2010): Atomate it! end-user context-sensitive automation using heterogeneous information sources on the web. In: Proceedings of the 2010 International Conference on the World Wide Web 2010. pp. 951-960. Available online

The transition of personal information management (PIM) tools off the desktop to the Web presents an opportunity to augment these tools with capabilities provided by the wealth of real-time information readily available. In this paper, we describe a next-generation personal information assistance engine that lets end-users delegate to it various simple context- and activity-reactive tasks and reminders. Our system, Atomate, treats RSS/ATOM feeds from social networking and life-tracking sites as sensor streams, integrating information from such feeds into a simple unified RDF world model representing people, places and things and their timevarying states and activities. Combined with other information sources on the web, including the user's online calendar, web-based e-mail client, news feeds and messaging services, Atomate can be made to automatically carry out a variety of simple tasks for the user, ranging from context-aware filtering and messaging, to sharing and social coordination actions. Atomate's open architecture and world model easily accommodate new information sources and actions via the addition of feeds and web services. To make routine use of the system easy for non-programmers, Atomate provides a constrained-input natural language interface (CNLI) for behavior specification, and a direct-manipulation interface for inspecting and updating its world model.

Teevan, Jaime, Cutrell, Edward, Fisher, Danyel, Drucker, Steven M., Ramos, Gonzalo, André, Paul and Hu, Chang (2009): Visual snippets: summarizing web pages for search and revisitation. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2023-2032. Available online

People regularly interact with different representations of Web pages. A person looking for new information may initially find a Web page represented as a short snippet rendered by a search engine. When he wants to return to the same page the next day, the page may instead be represented by a link in his browser history. Previous research has explored how to best represent Web pages in support of specific task types, but, as we find in this paper, consistency in representation across tasks is also important. We explore how different representations are used in a variety of contexts and present a compact representation that supports both the identification of new, relevant Web pages and the re-finding of previously viewed pages.

André, Paul, Teevan, Jaime and Dumais, Susan (2009): From x-rays to silly putty via Uranus: serendipity and its role in web search. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2033-2036. Available online

The act of encountering information unexpectedly has long been identified as valuable, both as a joy in itself and as part of task-focused problem solving. There has been a concern that highly accurate search engines and targeted personalization may reduce opportunities for serendipity on the Web. We examine whether there is the potential for serendipitous encounters during Web search, and whether improving search relevance through personalization reduces this potential. By studying Web search query logs and the results people judge relevant and interesting, we find many of the queries people perform return interesting (potentially serendipitous) results that are not directly relevant. Rather than harming serendipity, personalization appears to identify interesting results in addition to relevant ones.

Schraefel, MC, André, Paul, White, Ryen, Tan, Desney, Berners-Lee, Tim, Consolvo, Sunny, Jacobs, Robert, Kohane, Issac, Dantec, Christopher A. La, Mamykina, Lena, Marsden, Gary and Shneiderman, Ben (2009): Interacting with eHealth: towards grand challenges for HCI. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3309-3312. Available online

While health records are increasingly stored electronically, we have little access to this data about ourselves. We're not used to thinking of these official records either as ours or as something we'd understand if we had access to them in any case. We increasingly turn to the Web, however, to query any ache, pain or health goal we may have before consulting with health care professionals. Likewise, for proactive health care, such as nutrition or fitness, or post diagnosis support, to find fellow-sufferers, we turn to online resources. There is, it seems, a potential disconnect between points at which professional and proactive health care intersect. Such gaps in information sharing may have direct impact on practices we decide to take up, the care we seek, and the support professionals offer. In this panel, we consider several places within proactive, preventative health care in particular HCI has a role towards enhancing health knowledge discovery and health support interaction. Our goal is to demonstrate how now is the time for eHealth to come to the forefront of the HCI research agenda.

Bernstein, Michael, André, Paul, Luther, Kurt, Solovey, Erin Treacy, Poole, Erika S., Paul, Sharoda A., Kane, Shaun K. and Grudin, Jonathan (2009): CHIstory. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3493-3494. Available online

How might the world view human-computer interaction a century from now? In this video, set one hundred years in the future, we playfully re-envision the early history of HCI. As the video opens, the Great Usability Cataclysm of 2068 has erased all previous knowledge of HCI. The world has been plunged into an age of darkness where terror, fear, and poor usability reign. Unearthing fragments of previously lost archival footage, a disembodied HCI historian (Jonathan Grudin) introduces a first attempt to reconstruct the history of our field. Pioneering systems like NLS and Sketchpad are reviewed alongside more recent work from CHI and related conferences. The results may surprise and perplex as much as they entertain, but most of all, we hope they inspire reflection on the past and future of our field.

schraefel, m.c., White, Ryen W., André, Paul and Tan, Desney (2009): Investigating web search strategies and forum use to support diet and weight loss. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3829-3834. Available online

Healthcare is shifting from being reactive to preventive, with a focus on maintaining general wellness through positive decisions on diet, exercise, and lifestyle. In this paper, we investigate search behavior as people navigate the Web and find support for dietary and weight loss plans. Inspecting the Web search logs of nearly 2,000 users, we show that people progressively narrow their searches to support their progress through these plans. Interestingly, people that visit online health forums seem to progress through the plans' phases more quickly. Based on these results, we conducted a survey to further explore the roles and importance of online forums in supporting dieting and weight loss.

André, Paul, schraefel, m.c., Teevan, Jaime and Dumais, Susan (2009): Discovery is never by chance: designing for (un)serendipity. In: Proceedings of the 2009 Conference on Creativity and Cognition 2009. pp. 305-314. Available online

Serendipity has a long tradition in the history of science as having played a key role in many significant discoveries. Computer scientists, valuing the role of serendipity in discovery, have attempted to design systems that encourage serendipity. However, that research has focused primarily on only one aspect of serendipity: that of chance encounters. In reality, for serendipity to be valuable chance encounters must be synthesized into insight. In this paper we show, through a formal consideration of serendipity and analysis of how various systems have seized on attributes of interpreting serendipity, that there is a richer space for design to support serendipitous creativity, innovation and discovery than has been tapped to date. We discuss how ideas might be encoded to be shared or discovered by 'association-hunting' agents. We propose considering not only the inventor's role in perceiving serendipity, but also how that inventor's perception may be enhanced to increase the opportunity for serendipity. We explore the role of environment and how we can better enable serendipitous discoveries to find a home more readily and immediately.

André, Paul, Wilson, Max L., Russell, Alistair, Smith, Daniel A., Owens, Alisdair and Schraefel, M. C. (2007): Continuum: designing timelines for hierarchies, relationships and scale. In: Proceedings of the ACM Symposium on User Interface Software and Technology October 7-10, 2007, Newport, Rhode Island, USA. pp. 101-110. Available online

Temporal events, while often discrete, also have interesting relationships within and across times: larger events are often collections of smaller more discrete events (battles within wars; artists' works within a form); events at one point also have correlations with events at other points (a play written in one period is related to its performance over a period of time). Most temporal visualisations, however, only represent discrete data points or single data types along a single timeline: this event started here and ended there; this work was published at this time; this tag was popular for this period. In order to represent richer, faceted attributes of temporal events, we present Continuum. Continuum enables hierarchical relationships in temporal data to be represented and explored; it enables relationships between events across periods to be expressed, and in particular it enables user-determined control over the level of detail of any facet of interest so that the person using the system can determine a focus point, no matter the level of zoom over the temporal space. We present the factors motivating our approach, our evaluation and implementation of this new visualisation which makes it easy for anyone to apply this interface to rich, large-scale datasets with temporal data.
