Mixed and Virtual Reality (XR) have seen an important development since the advent of low-cost technologies. The application space is still diversifying, opening up new opportunities and application areas for such technologies. An important common feature of Mixed and Virtual Reality applications is that designers and engineers need to orchestrate virtual content and user experience. We regard orchestration of Mixed and Virtual Reality as invisible work: in many cases, orchestration is hidden within the task of story scripting of applications. It is often occluded by designing and programming Mixed and Virtual Reality. As such, orchestration is regarded as a means to a goal, which occludes its importance for the design of XR systems. We would like to invite the research community to address this issue, by focusing this workshop on highlighting and exemplifying orchestration challenges and best practices, and to systematise the orchestration topic in the context of the recent technology advances. We will consider a wide range of orchestration cases, from completely pre-orchestrated to live-orchestrated Mixed and Virtual Reality. Based on that knowledge, we aim to consider novel tools to support designers and users in their orchestration work. We invite scholars and practitioners to contribute to our workshop, with cases from their work.

Movement plays an increasingly important role in interactive systems design, from users’ physical engagement, to how designed artefacts can move or be moved, and to the concert between users and artefacts. Designers, as well as programmers, have to engage more and more in physical activities when they want to create appealing experiences involving movement. There is a need for articulating emerging dialogues between designers, developers, and their materials. We will explore such dialogues in a 2-half-day workshop, focusing on data and its challenges, on tools and methods, on sensing and actuation when designing or detecting subtle body movements, and on catering for bodily changes over time.

Design of eco-feedback has primarily aimed at persuading individuals to change behaviours into more environmentally sustainable ones. However, it has been questioned how effective such feedback is in supporting long-term change. As an alternative focus for energy feedback, we present a case study of amateur energy management work in apartment buildings owned by housing cooperatives, and the design of an app that aims to stimulate and support cooperatives in taking energy actions that significantly reduce the cooperative’s collective energy use. By linking energy data to energy actions, the users can see how actions taken in their own and other cooperatives affected the energy use, learn from each other’s experiences and become motivated as energy amateurs. Based on our housing cooperative case, we reflect on design aspects to consider when designing for energy management in amateur settings. QC 20160714

The use of practices as a unit of analysis has been suggested in order to scale up efforts within sustainable HCI and to shift the focus from changing individual behaviours to supporting transitions at a societal level. In this paper, we take a practice approach to the case of sustainable transportation, and more specifically to car-free transportation. Car use is intertwined in many practices and managing life without a car is difficult, particularly for people in contexts where owning at least one car per family is the norm. We studied three families in Stockholm who replaced their cars with different combinations of light electric vehicles during one year. From the families' experiences, we identified a number of opportunities for designers of interactive technologies to support environmental pioneers in the particular case of car-free living, as well as to support transitions towards sustainable practices in general.

In this paper we present a visualization of estimated and real energy consumption while driving, as a tool to compare the driving to what might be considered "typical" driving. This is particularly relvant to cases where the driver wants to be aware of the energy consumption in order to reach a particular destination and avoid a "lead foot", or otherwise when learning to drive efficiently.

Energy and design of energy-feedback are becoming increasingly important in the mobile HCI community. Our application area concerns electric vehicles, we thus depart from home and workplace appliances and address range and energy anxiety caused by short driving distance capabilities and long charging times in mobile settings. Meanwhile some research has been done on energy management of mobile devices, less has been done on mobility devices like electric vehicles. We explore this topic by letting conventional fuel car drivers reflect on their current driving habits through an exploration tool that we developed. Our results demonstrate three dimensions related to energy availability to consider for design of energy dependent mobility devices and provide explanations on how these dimensions could be utilize in our design through energy visualizations. With this we contributed not only by demonstrating aspects of energy availability and mobility, but also through opening up for new interesting possibilities and inquires in our and possibly other domains.

We address the issue of sustainability of practice, which we regard as crucial for the sustainability of the community at large. In the absence of material reward, sustaining a specialized activity such as programming is not trivial especially when members move often in and out of the community. Our case is the group of voluntary, amateur student programmers from a European-wide student organization. We present this setting as an Amateur Community and as a Community of Practice, and show how such framing helps in understanding sustainability of practice. Although being totally voluntary and managing a large intranet, the group has been thriving for six years. To explain such high practice sustainability we examine the role of the technology framework used by the group during this time. We then propose a more general framework for understanding practice sustainability in the context of amateur communities of practice.

Communication between humans is multimodal and involves movements as well. While communication between humans and robots is becoming more and more multimodal, movements of a robot in 2D space have not yet been used for communication. In this paper, we present a new approach to multimodal communication with (semi-)autonomous robots, that even includes movements of a robot in 2D space as a form of expressing communicative acts. We also show how such a multimodal human-robot interface can be generated from a discourse-based interaction design that does not even include information about modalities.

End users of software typically have to let someone else develop it and its user interface, or to learn to design and to program it themselves. Especially user interfaces developed by someone else may not fit well the given task. Designing and programming is hard and takes a lot of effort in general, and even more so for people not especially trained or experienced.Therefore, we propose end-user development of user interfaces through a new approach and interface for discourse modeling. End users may themselves model an interaction design as a discourse (in the sense of a dialogue between human and computer). From such an interaction design, eventually a user interface is to be generated automatically by a tool. As a consequence, end-user development becomes end-user modeling instead of programming.

Most current models of interaction design build on scenarios and task analysis. We think that interaction design should be more along the lines of communication between humans. With this motivation, our paper presents a new approach to modeling interaction design based on insights from theories of human communication. From such discourse models, we aim for automated generation of user interfaces.

We present the initial stages of a project in which we focus on participatory design methods to build information and communication technology support that stimulate knowledge sharing in a group of geographically distributed teachers. Teachers in general spend most of their time in a classroom leaving few opportunities for social encounters and chats with their colleagues. The prototype we are developing focuses on informality and playfulness, that would increase the social communication and thereby the community feeling. In turn, this would ultimately increase learning among the setting members.

We report on a pilot study that is part of an ongoing project which investigates social awareness support for project groups made of students who may choose to work at the university, at home or at part-time job offices. The study involved the design and early evaluation of a prototype which augments a cooperative application with various sensorial and computational cues about co-worker presence. The sensing devices were installed and annotated by the users themselves. Based on this experience and inspired by "technomethodology", we suggest implications for design of awareness support and context-enabled devices.
