Interaction techniques for mobile collocation

Research on mobile collocated interactions has been exploring situations where collocated users engage in collaborative activities using their personal mobile devices (e.g., smartphones and tablets), thus going from personal/individual toward shared/multiuser experiences and interactions. The proliferation of ever- smaller computers that can be worn on our wrists (e.g., Apple Watch) and other parts of the body (e.g., Google Glass), have expanded the possibilities and increased the complexity of interaction in what we term “mobile collocated” situations. The focus of this workshop is to bring together a community of researchers, designers and practitioners to explore novel interaction techniques for mobile collocated interactions

Collaborative use of mobile devices to curate sources of inspiration

We demonstrate a prototype mobile application designed to support individually collecting personal sources of inspiration on mobile phones, and then the sharing and curating of these collected materials in a face-to-face situation

Legal and Ethical Implications of Mobile Live-Streaming Video Apps

The introduction of mobile apps such as Meerkat, Periscope, and Facebook Live has sparked enthusiasm for live-streaming video. This study explores the legal and ethical implications of mobile live-streaming video apps through a review of public-policy considerations and the computing literature as well as analyses of a mix of quantitative and qualitative user data. We identify lines of research inquiry for five policy challenges and two areas of the literature in which the impact of these apps is so far unaddressed. The detailed data gathered from these inquiries will significantly contribute to the design and development of tools, signals or affordances to address the concerns that our study identifies. We hope our work will help shape the fields of ubiquitous computing and collaborative and social computing, jurisprudence, public policy and applied ethics in the future

Digital technologies applied to the accessible management of museums. The first experiments carried out at the Museum of Oriental Art of Turin

[EN] The proposed research focuses on the museum context of the city of Turin (Italy), within an ongoing framework agreement between the Politecnico di Torino and the Museum of Oriental Art (MAO). It aims at the construction of a model for the management of the workflow that includes the digital survey, the 3D virtual modelling and the digital fabrication of the tactile models of the artworks and the exhibition spaces. The paper starts with an overview on the methods of conservation and dissemination of cultural and architectural heritage, on the accessibility of museums and on tactile perception and graphics. It presents the first outcomes of the designed workflow with a special focus on the digital fabrication experiments on the vaulted system of the atrium of Palazzo Mazzonis (MAO home). The founding idea is that tactile exploration of artifacts helps the visitor engagement, making the museum experience more educationally incisive and more inclusive, in a “Design for All” perspective.[ES] La investigación propuesta se centra en el contexto museístico de la ciudad de Turín (Italia), dentro de un acuerdo marco en curso entre el Politecnico di Torino y el Museo de Arte Oriental (MAO). Su objetivo es la construcción de un modelo para la gestión del flujo de trabajo que parte de la digitalización de las obras de arte y de los espacios y termina con la realización de modelos táctiles. El artículo comienza con una visión general sobre los métodos de conservación y difusión del patrimonio cultural y arquitectónico sobre la percepción y los gráficos táctiles. Presenta los primeros resultados del flujo de trabajo diseñado, centrándose especialmente en los experimentos de fabricación digital en el sistema abovedado del atrio del Palazzo Mazzonis (casa del MAO).

Sensing with Earables: A Systematic Literature Review and Taxonomy of Phenomena

Earables have emerged as a unique platform for ubiquitous computing by augmenting ear-worn devices with state-of-the-art sensing. This new platform has spurred a wealth of new research exploring what can be detected on a wearable, small form factor. As a sensing platform, the ears are less susceptible to motion artifacts and are located in close proximity to a number of important anatomical structures including the brain, blood vessels, and facial muscles which reveal a wealth of information. They can be easily reached by the hands and the ear canal itself is affected by mouth, face, and head movements. We have conducted a systematic literature review of 271 earable publications from the ACM and IEEE libraries. These were synthesized into an open-ended taxonomy of 47 different phenomena that can be sensed in, on, or around the ear. Through analysis, we identify 13 fundamental phenomena from which all other phenomena can be derived, and discuss the different sensors and sensing principles used to detect them. We comprehensively review the phenomena in four main areas of (i) physiological monitoring and health, (ii) movement and activity, (iii) interaction, and (iv) authentication and identification. This breadth highlights the potential that earables have to offer as a ubiquitous, general-purpose platform

Integrating passive ubiquitous surfaces into human-computer interaction

Mobile technologies enable people to interact with computers ubiquitously. This dissertation investigates how ordinary, ubiquitous surfaces can be integrated into human-computer interaction to extend the interaction space beyond the edge of the display. It turns out that acoustic and tactile features generated during an interaction can be combined to identify input events, the user, and the surface. In addition, it is shown that a heterogeneous distribution of different surfaces is particularly suitable for realizing versatile interaction modalities. However, privacy concerns must be considered when selecting sensors, and context can be crucial in determining whether and what interaction to perform.Mobile Technologien ermöglichen den Menschen eine allgegenwärtige Interaktion mit Computern. Diese Dissertation untersucht, wie gewöhnliche, allgegenwärtige Oberflächen in die Mensch-Computer-Interaktion integriert werden können, um den Interaktionsraum über den Rand des Displays hinaus zu erweitern. Es stellt sich heraus, dass akustische und taktile Merkmale, die während einer Interaktion erzeugt werden, kombiniert werden können, um Eingabeereignisse, den Benutzer und die Oberfläche zu identifizieren. Darüber hinaus wird gezeigt, dass eine heterogene Verteilung verschiedener Oberflächen besonders geeignet ist, um vielfältige Interaktionsmodalitäten zu realisieren. Bei der Auswahl der Sensoren müssen jedoch Datenschutzaspekte berücksichtigt werden, und der Kontext kann entscheidend dafür sein, ob und welche Interaktion durchgeführt werden soll

The binge-watcher’s journey: Investigating motivations, contexts, and affective states surrounding Netflix viewing

The growth of Internet-distributed TV services has transformed video consumption, enhancing the level of control that viewers have over what they watch. Along with the release of entire seasons of programming at once, this has led to the phenomenon of ‘binge-watching’, in which several episodes of a program are viewed in one sitting. This article presents the results of a novel exploratory study focused on 40 Netflix viewing sessions from 11 millennials in their homes. Methodologically, we employed a novel mixed-methods approach that combines objective data (collected through a browser extension) and subjective data (collected via questionnaires completed before and after viewing). This novel approach allowed us to describe the binge-watcher’s experience in a holistic fashion. Results suggest that binge-watching is an individual activity mainly performed at the end of the day to relax, for boredom relief purposes, or for escapism. Furthermore, a binge-watching session lasts for an average of 2 h and 10 min, and variations on binge-watchers’ affective states were identified after Netflix exposure. Participants’ levels of valence (unhappy–happy) significantly decreased after binge-watching; their positive affect values increased primarily after watching sci-fi, while their negative affect values decreased after watching comedy and slightly increased after watching drama. However, the levels of arousal (relaxed–stimulated) remained the same. This study extends our current understanding of binge-watching in terms of viewer motivations, how it affects their viewing experiences, and participants’ subjective affective states. The investigation contributes, thus

Synapse: Interactive Guidance by Demonstration with Trial-and-Error Support for Older Adults to Use Smartphone Apps

As smartphones are widely adopted, mobile applications (apps) are emerging to provide critical services such as food delivery and telemedicine. While bring convenience to everyday life, this trend may create barriers for older adults who tend to be less tech-savvy than young people. In-person or screen sharing support is helpful but limited by the help-givers' availability. Video tutorials can be useful but require users to switch contexts between watching the tutorial and performing the corresponding actions in the app, which is cumbersome to do on a mobile phone. Although interactive tutorials have been shown to be promising, none was designed for older adults. Furthermore, the trial-and-error approach has been shown to be beneficial for older adults, but they often lack support to use the approach. Inspired by both interactive tutorials and trial-and-error approach, we designed an app-independent mobile service, \textit{Synapse}, for help-givers to create a multimodal interactive tutorial on a smartphone and for help-receivers (e.g., older adults) to receive interactive guidance with trial-and-error support when they work on the same task. We conducted a user study with 18 older adults who were 60 and over. Our quantitative and qualitative results show that Synapse provided better support than the traditional video approach and enabled participants to feel more confident and motivated. Lastly, we present further design considerations to better support older adults with trial-and-error on smartphones

What common design principles can be distilled out from literature in the field of technologies and learning difficulties that might inform the design of technologies within the EU funded ARCHES Project?

The focus of this research report is people who have diverse access needs associated with perception, memory, cognition and communication- those who are frequently ascribed the label of ‘learning difficulties’1 and the technologies that may help to enhance their access to and inclusion into cultural and heritage sites (including digital assets)
