Companies are now making video-communication systems that allow pet owners to see, and, in some cases, even interact with their pets when they are separated by distance. Such 'doggie cams' show promise, yet it is not clear how pet video chat systems should be designed (if at all) in order to meet the real needs of pet owners. To investigate the potential of interactive dog cams, we then designed our own pet video chat system that augments a Skype audio-video connection with remote interaction features and evaluated it with pet owners to understand its usage. Our results show promise for pet video chat systems that allow owners to see and interact with their pets while away. © 2012 ACM.

We designed and ran an experiment to measure social influence in online recommender systems, specifically how often people's choices are changed by others' recommendations when facing different levels of confirmation and conformity pressures. In our experiment participants were first asked to provide their preferences between pairs of items. They were then asked to make second choices about the same pairs with knowledge of others' preferences. Our results show that others people's opinions significantly sway people's own choices. The influence is stronger when people are required to make their second decision sometime later (22.4%) than immediately (14.1%). Moreover, people seem to be most likely to reverse their choices when facing a moderate, as opposed to large, number of opposing opinions. Finally, the time people spend making the first decision significantly predicts whether they will reverse their decisions later on, while demographics such as age and gender do not. These results have implications for consumer behavior research as well as online marketing strategies. Copyright 2012 ACM.

Exploring large network datasets, such as scientific collab.ration networks, is challenging because they often contain a large number of nodes and edges in several types and with multiple attributes. Analyses of such networks are often long and complex, and may require several sessions by multiple users. Therefore, it is often difficult for users to recall their own exploration history or share it with others. We introduce GraphTrail, an interactive visualization for analyzing networks through exploration of node and edge aggregates that captures users' interactions and integrates this history directly in the exploration workspace. To facilitate large network analysis, GraphTrail integrates aggregation with familiar charts, drag-and-drop interaction on a canvas, and a novel pivoting mechanism for transitioning between aggregates. Through a three-month field study with a team of archeologists and a qualitative lab.study with ten users, we demonstrate the effectiveness of our design and the benefits of integrated exploration history, including analysis comprehension, insight discovery, and exploration recall.

We developed a framework for systematic evaluation of BCI systems. This framework is intended to compare features extracted from a variety of spectral measures related to functional connectivity, effective connectivity, or instantaneous power. Different measures are treated in a consistent manner, allowing fair comparison within a repeated measures design. We applied the framework to BCI data from 14 subjects recorded on two days each, and demonstrated the framework's feasibility by confirming results from the literature. Furthermore, we could show that electrode selection becomes more focal in the second BCI session, but classification accuracy stays unchanged. © 2012 Springer-Verlag.

Hybrid paper-digital interfaces are a promising approach for supporting language activities. The familiarity of pen and paper makes it a particularly attractive media for many user groups, including young children. Digital pens enhance interaction with traditional paper content by playing and recording audio and recognizing handwriting and gestures. Currently, generating custom interactive paper documents involves some programming, limiting its use by many user groups (e.g., educators and families) who might especially benefit from application of hybrid paper-digital interfaces in their practices. To address this need, we developed an enduser Toolkit for Authoring Pen and Paper Language Activities (TAP & PLAY). This paper describes the iterative development of the toolkit, its accessibility for novice non-technical users, and use in three different contexts for early language learning. We demonstrate and document the system's usability, generality, and utility for people who want to create and tailor their own custom interactive paper-based language activities. Copyright 2012 ACM.

Researchers from many disciplines are taking advantage of increasingly inexpensive digital video to capture extensive records of human activity in real-world settings. The ability to record and share such data has created a critical moment in the practice and scope of behavioral research. While recent work [3, 5] is beginning to develop techniques for visualizing and interacting with integrated multimodal information collected during field research, navigating and analyzing these large datasets remains challenging and tools are especially needed to support the early stages of data exploration. In this paper we describe digital pen and paper practices in observational research and their integration with ChronoViz [4], a tool for annotating, visualizing, and analyzing multimodal data. The goal is to better support researchers both in the field, while collecting data, and later in the lab. during analysis. We document the co-evolution of notetaking practices and system features as 28 participants used the tool during an 18-month deployment. Copyright 2012 ACM.

Bridging languages in social networks: How multilingual users of Twitter connect language communities?

Proceedings of the ASIST Annual Meeting 2012年第1期49卷 1-4页

Multilingual users of social media and social networking sites are invisible -even unconscious- translators. Their language skills and multicultural background could help diminish the segmentation of information spheres online by connecting different language communities. Focusing on the microblogging site Twitter, this study aims at defining and classifying language bridges by looking at the languages and structure of the social networks of multilingual individuals. The social network analysis unveils four types of structures, one of which is defined as a language bridge. The next step of this work in progress aims at providing quantitative measures of this phenomenon, which has not been yet properly described or understood.

The goal of this study is to compare social tagging patterns in two languages in image collections of art, while seeking exploitable strengths for the application of multilingual social tagging in digital libraries and museums. Crowdsourcing the annotation of digital image collections of artworks to different language communities has the potential to bridge language borders and reach wider audiences. This mixed methods study is based on a collection of digital images of paintings for which tags in Spanish and English were collected. The results show that the level of agreement in the vocabulary describing an image does not change significantly when adding a second language, but different cultural perspectives can be found for certain images when comparing less frequent tags across languages. Understanding and comparing tagging behaviors across languages is necessary for the design of user interfaces that support diversity and encourage sharing of perspectives about the artwork images. © 2012 ACM.

Over a decade ago Hallnäs and Redström's seminal article on Slow Technology [6] argued that the increasing availab.lity of technology in environments outside of the workplace requires interaction design to be expanded from creating tools for making people's lives more efficient to creating technology that could be embedded in everyday environments over long periods of time. Since then, the Slow Technology design agenda has expanded to include issues such as (i) designing for slowness, solitude, and mental rest, (ii) designing interactive systems to be used across multiple generations and lifespans, and (iii) designing for slower, less consumptive lifestyles and practices. This workshop aims to advance the Slow Technology design program by exploring the various practical, methodological and theoretical motivations, challenges, and approaches implicated in doing research and design in this growing space. © 2012 ACM.
