A recent study found that presenting news suggestions as clusters in a sidebar can lead to more exploration of articles and clusters related to particular stories [1]. We conducted a lab study to test the robustness of the result.Our results only partially replicate the original findings: people read more articles, but not from significantly more clusters;we also foundthat they prefer the clustered presentation. Further research is needed to better understand the conditions under which clustered presentation leads people to sample from more clusters.

We introduce Tangeo, a drawing system that combines tangible drawing tools, such as rulers, protractors and set squares with a table-top environment. Geometric drawing on computers is often constrained to abstract widget tools and metaphoric, indirect input methods such as mouse and keyboard. Tangeo allows users to construct geometric drawings in a more direct manner by manipulating virtual data with familiar physical objects and drawing with a finger. User evaluations on Tangeo yielded a high rate of user satisfaction and indicated that the system is effective at enhancing geometric drawing.

Usability of interactive web forms is a critical aspect of the overall user experience. In this paper, a tool to automatically evaluate web form filling tasks is presented. The tool carries out Keystroke Level Model symbolic calculations of the time required to fill a specific web form in a straightforward and automatic manner. Moreover, it calculates the form completion time according to different interaction strategies or users' characteristics. In addition, Fitts' law is computationally realized to calculate the exact time required to move the cursor to the form elements. Preliminary case studies illustrated the tool capability to support both designers and evaluators in an efficient and effective manner.

To create digital art, skillsets from a variety of disciplines are combined to form a finished aesthetic product. An artist may engage in hybrid practice, building his/her own technologies, or may collaborate with specialized technicians to form a creative team. This workshop will bring together participants from a variety of disciplines and backgrounds, including art, music, design, and engineering to explore how the technological aspects of digital art function not merely in service to artistic considerations but rather, have creative and communicative value in their own right. We will discuss how explicit valuation of technical process in interdisciplinary design affects the experience of digital art creation, and explore how technology itself is and can be aestheticized in digital art practice. We will use these concepts to frame an investigation of how engagement with digital art practice can be used to enrich HCI.

Third places are places that are neither home nor work, where people voluntarily come together to socialize. Third places are essential to social life because they provide a common ground where different communities can meet, and they promote a sense of place. Emerging information and communication technologies (ICT) are changing the way we use such third places, altering how we interact with other people and how communities are formed. The goal of the first Workshop on Human Computer Interaction in Third Places is to provide a forum where researchers can discuss the intersection between computing and third places. We aim to develop a research agenda and to initiate collaboration between researchers to better understand the roles of ICT in such places.

An innovative type of keyboard-driven mouse control, called DualMouse, is introduced. In addition to allowing its user to perform pointer operations using the keyboard only, the technique, currently implemented as a stand-alone program, facilitates precise clicking by zooming in on the target area. This work is part of a larger project about OnScreenDualScribe, a tool tailored to the needs of persons with neuromuscular diseases, replacing the large standard keyboard with a small number pad-like special-purpose keyboard. Although OnScreenDualScribe has its primary focus on text entry, efficient usage calls for an integrated mouse mode. We believe that DualMouse has the potential to make OnScreenDualScribe an even more helpful tool, and we justify that claim by comparing it to other possibilities.

As has been apparent for the past several months, MOOCs (Massive Online Open Courseware) have emerged as a powerful contender for the next new education technology. Yet the landscape of education technology is littered with the remains of previous technological breakthroughs that have failed to live up to their initial promise, or at least their initial rhetoric. This panel will present a lively debate about the promise, and realities, of MOOCs and whether they are transformative, or merely a faddish trend.

This work in progress -paper describes our efforts in developing trampoline training games using computer vision technology. The study is part of a project about developing digitally augmented exercise environments for faster, safer and more engaging sports training. We describe four initial prototypes and the feedback obtained from testing them both with circus students and with people with no background in trampolining.

A few studies have attempted to provide metrics of success in open source software (OSS) projects but the role a code hosting workspace plays in how performance is viewed and measured is little examined. We conducted qualitative, exploratory research with lead and core developers on three successful projects on GitHub to understand how OSS communities on GitHub measure success. These results were obtained in connection with a larger project that is designed to understand the structure of code hosting platforms in relation to participation and performance. We report two main findings. First, lead and core members of the projects we interviewed display a nuanced understanding of community participation in their assessment of success. Second, they attribute increased participation on their projects to the features and usability provided by GitHub.
