Contextual gaps: privacy issues on Facebook

Social networking sites like Facebook are rapidly gaining in popularity. At the same time, they seem to present significant privacy issues for their users. We analyze two of Facebooks’s more recent features, Applications and News Feed, from the perspective enabled by Helen Nissenbaum’s treatment of privacy as “contextual integrity.” Offline, privacy is mediated by highly granular social contexts. Online contexts, including social networking sites, lack much of this granularity. These contextual gaps are at the root of many of the sites’ privacy issues. Applications, which nearly invisibly shares not just a users’, but a user’s friends’ information with third parties, clearly violates standard norms of information flow. News Feed is a more complex case, because it involves not just questions of privacy, but also of program interface and of the meaning of “friendship” online. In both cases, many of the privacy issues on Facebook are primarily design issues, which could be ameliorated by an interface that made the flows of information more transparent to users.

Creativity factor evaluation: towards a standardized survey metric for creativity support

We present a new survey metric, the Creativity Support Index (CSI) that is designed to help researchers and designers evaluate the level of creativity support provided by various systems or interfaces. We initially employed a top-down literature-based approach to develop a beta version of the Creativity Support Index (Beta CSI). We discuss our usage of the Beta CSI in three different studies and what we learned from those deployments. We also present the results from an extensive creativity vocabulary study (n=300), which revealed a set of orthogonal creativity factors. This led to the current version of the CSI presented in this paper. Initial results from these formative evaluations suggest the value of this tool in assessing and comparing creativity support tools at points in time and longitudinally.

Love, hate, arousal and engagement: exploring audience responses to performing arts

Understanding audience responses to art and performance is a challenge. New sensors are promising for measurement of implicit and explicit audience engagement. However, the meaning of biometric data, and its relationship to engagement, is unclear. We conceptually explore the audience engagement domain to uncover opportunities and challenges in the assessment and interpretation of audience engagement data. We developed a display that linked performance videos with audience biometric data and presented it to 7 performing arts experts, to explore the measurement, interpretation and application of biometric data. Experts were intrigued by the response data and reflective in interpreting it. We deepened our inquiry with an empirical study with 49 participants who watched a video of a dance performance. We related temporal galvanic skin response (GSR) data to two self-report scales, which provided insights on interpreting this measure. Our findings, which include strong correlations, support the interpretation of GSR as a valid representation of audience engagement.

Quantifying the Creativity Support of Digital Tools through the Creativity Support Index

Creativity support tools help people engage creatively with the world, but measuring how well a tool supports creativity is challenging since creativity is ill-defined. To this end, we developed the Creativity Support Index (CSI), which is a psychometric survey designed for evaluating the ability of a creativity support tool to assist a user engaged in creative work. The CSI measures six dimensions of creativity support: Exploration, Expressiveness, Immersion, Enjoyment, Results Worth Effort, and Collaboration. The CSI allows researchers to understand not just how well a tool supports creative work overall, but what aspects of creativity support may need attention. In this article, we present the CSI, along with scenarios for how it can be deployed in a variety of HCI research settings and how the CSI scores can help target design improvements. We also present the iterative, rigorous development and validation process used to create the CSI.

Will massive online open courses (moocs) change education

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.

The choreographer's notebook: a video annotation system for dancers and choreographers

We present a collaborative tool for choreographers and dancers, the Choreographers Notebook, which allows multimodal annotation of rehearsal videos during the dance production process. The dance production process is a creative process in which exploration and expression are paramount and we describe issues we have observed over four different dance production cycles. The Choreographers Notebook addresses the recurring problem of scarcity of rehearsal time and space, which is a limiting factor for exploration and expression. The tool is a web-based video application that enables choreographers to provide multimodal, context-sensitive instructions and feedback to the dancers outside of formal rehearsal time. The novelty of this tool is its ability to provide a multimodal collaborative video-based workflow. This article also presents a thorough ethnographic investigation of the dance production process and results from the use of the Choreographers Notebook as an artifact within that process.

Dance-inspired technology, technology-inspired dance

The design of interactive dance is a challenging endeavor because both dance and computing are in themselves full of complexity, thus to create a cohesive union of the two involves much trial and error and a mutual disciplinary understanding. Since interactive dance is a performing art, technologists working as designers must consider how all of the parts -- choreography, media, interactivity -- are integrated to inform the overall gestalt and intent of the piece. To this end, we offer five design principles for making interactive dance: Connected Kinetics, Augmented Expression, Aesthetic Harmony, Interactive Build, and Integrated Process. These design principles have emerged from our practice-based research in collaboratively producing six different interactive dance pieces over the past four years.

Evaluating longitudinal projects combining technology with temporal arts

The integration of interactive technology with temporal art such as dance is an exciting, emerging area. The design space for such collaborations is immense, with variations in sensors, visualizations, and how these interact with dancers and choreography. This paper presents the evaluation methodology and results of Dance.Draw, a longitudinal project spanning two years and three productions, which aimed to develop a deep, interdisciplinary understanding of this space. Given that this is pioneering work, there is little guidance on how to evaluate such collaborations. We describe the significant confounds in doing evaluation in this area, and we present our evolving mixed-methods approach, which includes two unique methods to address the multiple stakeholders in a holistic manner: dancer focus groups and repeated presentations. Our approach has generated insights, such as differing perspectives of audience members and the responses of dancers to technological variables. We conclude by discussing the challenges and successes of our evaluation approach.

Visible Flows: Contextual Integrity and the Design of Privacy Mechanisms on Social Network Sites

Social Network Sites have a number of well publicized privacy issues stemming from the overdisclosure of personal information. On one hand, users seem oblivious to their privacy, doing little to protect their personal data. On the other hand, there have been a number of privacy uproars and backlashes due to certain site features or behaviors. In this paper, we explore the privacy issues in social network sites using contextual integrity, a recently proposed privacy framework. We use the framework to highlight a number of privacy issues on social network sites, and to propose a set of design guidelines and potential solutions.

Primary Care Providers’ Views of Patient Portals: Interview Study of Perceived Benefits and Consequences

Background The United States government is encouraging physicians to adopt patient portals—secure websites that allow patients to access their health information. For patient portals to recognize their full potential and improve patient care, health care providers’ acceptance and encouragement of their use will be essential. However, little is known about provider concerns or views of patient portals. Objective We conducted this qualitative study to determine how administrators, clinic staff, and health care providers at practices serving a lower income adult population viewed patient portals in terms of their potential benefit, areas of concern, and hopes for the future. Methods We performed in-depth interviews between October 2013 and June 2014 with 20 clinic personnel recruited from health centers in four North Carolina counties. Trained study personnel conducted individual interviews following an interviewer guide to elicit perceptions of the benefits and disadvantages of patient portals. Interviews were recorded and transcribed. Research team members reviewed transcribed interviews for major themes to construct a coding dictionary. Two researchers then coded each transcript with any coding discrepancies resolved through discussion. Results The interviews revealed that clinic personnel viewed patient portals as a mandated product that had potential to improve communication and enhance information sharing. However, they expressed many concerns including portals’ potential to generate more work, confuse patients, alienate non-users, and increase health disparities. Clinic personnel expected few older and disadvantaged patients to use a portal. Conclusions Given that clinic personnel have significant concerns about portals’ unintended consequences, their uptake and impact on care may be limited. Future studies should examine ways portals can be implemented in practices to address providers’ concerns and meet the needs of vulnerable populations.
