Multisensory augmented reality enables content developers to generate more realistic, sensory rich user experiences. Applications and research related to multisensory augmented reality expands through several areas such as education, medicine, human-machine interactions, human-food interactions, marketing, and neuroscience. Aim of this workshop is to gather researchers and industry representatives who are involved in multisensory augmented reality research to discuss the current state-of-the-art in the field, define future research directions, form new collaborations, and come up with future publication plans. We believe that this workshop would enhance the participants’ experience of the Interact 2021 and encourage more participants to attend the main conference.

Music streaming platforms are currently among the main sources of music consumption, and the embedded recommender systems significantly influence what the users consume. There is an increasing interest to ensure that those platforms and systems are fair. Yet, we first need to understand what fairness means in such a context. Although artists are the main content providers for music platforms, there is a research gap concerning the artists’ perspective. To fill this gap, we conducted interviews with music artists to understand how they are affected by current platforms and what improvements they deem necessary. Using a Qualitative Content Analysis, we identify the aspects that the artists consider relevant for fair platforms. In this paper, we discuss the following aspects derived from the interviews: fragmented presentation, reaching an audience, transparency, influencing users’ listening behavior, popularity bias, artists’ repertoire size, quotas for local music, gender balance, and new music. For some topics, our findings do not indicate a clear direction about the best way how music platforms should act and function; for other topics, though, there is a clear consensus among our interviewees: for these, the artists have a clear idea of the actions that should be taken so that music platforms will be fair also for the artists.

Part 1: Beyond Computers: Wearables, Humans, and Things - WHAT!; International audience; We introduce the rapid change of the visual art ecosystem, triggered by current science and technology development. ICT enables new multimedia based an interactive art forms, with an increasing variety of stakeholders. We provide examples of audience involvement, of immersion, and of brain-computer interaction as a new paradigm for participation. We point to the use of new material dimensions, as well as to expanding shared creation and cognition. We also point to opportunities to apply this development to accommodate special needs. In order to support the dissemination of these possibilities, we advocate the development of a task-modeling based ontology to describe, analyse, and support the evolving art ecosystem.

We examine the technological aspects of political collaborative practices in one of the first studies of participatory constitution writing in the course of its progression. In particular, we examine how digital collaborative and communicative tools can facilitate (or inhibit) the permeation of boundaries, which manifest through the differences in political ideologies and partisan beliefs. Our study is grounded in interviews with 15 members of the Constituent Assembly in the canton of Valais, Switzerland, and its primary contribution is in constructing a fine-grained contextualized understanding of political collaborations, their evolution, and their relationship with collaborative tools. Our findings demonstrate the centrality of versatile and widely available digital tools (such as WhatsApp and Google Docs) in political work. In addition, elected lawmakers prefer tools that allow them to organize their collaborative and communicative actions based on dynamic social boundaries, and their need for asynchronous work practices. We observed a tendency of simultaneously using multiple digital tools to accomplish specific political objectives, and leveraging them in plenary sessions for strategic advantages. On the one hand, collaborative tools enabled strategic advantages by selective permeation of boundaries across political ideologies. On the other hand, lack of awareness about boundaries between ‘private’ and ‘public’ on social networks were considered as privacy blind spots. By focusing on boundaries of different kinds, our paper elucidates how the introduction of digital technologies into political process transforms the long-established categories, distinctions and divisions that are often taken for granted.

International audience; Human-Computer Interaction (HCI) research has been focusing on properties such as usability, accessibility, inclusive design, user experience. As new security risks are emerging with the continuous increase of Internet interconnections and the development of the Internet of Things, more recently security, trust and resilience have also become important for the development of interactive systems. Since users have been identified as one of the major security weaknesses in today’s technologies, HCI becomes a fundamental pillar for designing more secure (but still usable) systems. However, interactive system properties might overlap and sometimes create conflicts in user-centered development processes. For example, security could reduce system usability by placing a burden on users when they have to deal with passwords. The HCI research has provided several tools and techniques that can support designers in making decisions, but there are no “cookbooks”. This workshop promotes sharing of experiences in managing and resolving conflicts of multiple interactive system properties within the context of a user-centered design process. We are concerned by theories, methods and approaches for dealing with interactive system properties, managing potential conflicts and trade-offs. This workshop is organized by the IFIP WG 13.2 on Methodology for User-Centered System Design and the IFIP WG 13.5 on Human Error, Resilience, Reliability and Safety in System Development.

With the proliferation of smartphones and wearables, Ecological Momentary Assessment (EMA) methods[1] are evolving into an indispensable component of practices that seek to collect data from a population of participants, through the use of their devices. In fields ranging from clinical psychology, to product design, to marketing and mHealth, the mobile devices owned by a population of participants can be made use of, and gather insights into how their daily lives unfold, by collecting data as reported from the participants themselves, or sensed by the devices. End-user programmable systems can aid these professionals and researchers manage the challenges that may arise in employing EMA methods with such devices.
