This workshop uses the outputs of a two-year Research through Design project as a springboard for bringing together a community of researchers interested in Hybrid Gifting. We have discovered that the many creative and socio-psychological processes involved in choosing or making a gift inform a great deal about interactions with common digital technologies, especially when they are used to make a hybrid gift with both physical and digital components. This workshop will be a temporally extended opportunity to experience the full cycle of giving and receiving gifts, whether you use our outputs or prototypes or your own ideas, artworks, or design fictions. Let’s take this opportunity to use our research to celebrate and care for each other, and perhaps envision new ways of celebrating and caring for others.

Gifting is socially and economically important. Studies of gifting physical objects have revealed motivations, values, and the tensions between them, while HCI research has revealed weaknesses of digital gifting and explored possibilities of hybrid gifting. We report an “in the wild” study of a hybrid chocolate gift deployed as a commercial product. Interviews reveal the experiences of receivers and givers, as well as the producer's friction points and tangible benefits. We reveal how in hybrid gifts the digital elevates the physical while the physical grounds the digital. We discuss how hybrid gifts bridge the tension between receiver-preference and relationship-signalling motivations, the need to further strengthen the exchange and reveal stages of hybrid gifting, and to manage the privacy of sensitive personal messages. We propose to extend the concept of hybrid wrapping to include a finer-grained interleaving of digital into complex packaging and multi-layered wrappings to create more holistic gifting experiences.

We explore how the convergence of the digital and physical into hybrid products leads to new possibilities for customization. We report on a technology probe, a hybrid advent calendar with both paper form and digital layers of content, both of which were designed to be customizable. We reveal how over two hundred active users adapted its physical and digital aspects in various ways, some anticipated and familiar, but others surprising. This leads us to contribute concepts to help understand and design for hybrid customization -- the idea of broad customization spanning physical and digital; end-to-end customization by different stakeholders along the value chain for a product; and the combination of these into customization maps.

Computing has become an established part of the built environment augmenting it to become adaptive.We generally assume that we control the adaptive environments we inhabit.Using an existing adaptive environment prototype, we conducted a controlled study testing how the reversal of control (where the environment attempts to influence the behaviour of the inhabitant) would affect participants.Most participants changed their respiratory behaviour in accordance with this environmental manipulation.Behavioural change occurred either consciously or unconsciously.We explain the two different paths leading participants to behavioural change: (i) we adapt the model of interbodily resonance, a process of bodily interaction observable between, for example, partners engaged in verbal dialogue, to describe the unconscious bodily response to subtle changes in the environment and (ii) we apply the model of secondary control, an adjustment of one's own expectations to maintain the pretence of control, to describe conscious cognitive adaptation to the changing environment.We also discuss potential applications of our findings in therapeutic and other settings. RESEARCH HIGHLIGHTS• We describe an experimental study of the control relationship in biofeedback environments.• Inhabitants on average synchronize their physiological behaviour when they lose control over the environment.• Inhabitant behaviour is explained through a form of interbodily resonance and secondary control.• We see potential therapeutic uses of combining biofeedback and automated control.

We explore the crafting of interactive decoration for everyday artefacts. This involves adorning them with decorative patterns that enhance their beauty while triggering digital interactions when scanned with cameras. These are realized using an existing augmented reality technique that embeds computer readable codes into the topological structures of hand-drawn patterns. We describe a research through design process that engaged artisans to craft a portfolio of interactive artefacts, including ceramic bowls, embroidered gift cards, fabric souvenirs, and an acoustic guitar. We annotate this portfolio with reflections on the crafting process, revealing how artisans addressed pattern, materials, form and function, and digital mappings throughout their craft process. Further reflection on our portfolio reveals how they bridged between human and system perceptions of visual patterns and engaged in a deep embedding of digital interactions into physical materials. Our findings demonstrate the potential for interactive decoration, distilling the craft knowledge involved in creating aesthetic and functional decoration, highlight the need for transparent computer vision technologies, and raise wider issues for HCI’s growing engagement with craft.

We explore how physical artefacts can be connected to digital records of where they have been, who they have encountered and what has happened to them, and how this can enhance their meaning and utility. We describe how a travelling technology probe in the form of an augmented acoustic guitar engaged users in a design conversation as it visited homes, studios, gigs, workshops and lessons, and how this revealed the diversity and utility of its digital record. We describe how this record was captured and flexibly mapped to the physical guitar and proxy artefacts. We contribute a conceptual framework for accountable artefacts that articulates how multiple and complex mappings between physical artefacts and their digital records may be created, appropriated, shared and interrogated to deliver accounts of provenance and use as well as methodological reflections on technology probes.

Both breathing and internal self-awareness are an integral part of any yoga practice. We describe and discuss the development of ExoPranayama, an actuated environment that physically manifests users’ breathing in yoga. Through a series of trials with yoga practitioners and expert teachers, we explore its role in the practice of yoga. Our interview results reveal that biofeedback through the environment supported teaching and improved self-awareness, but it impacted group cohesion. Two practical uses of the technology emerged for supporting breath control in yoga: (1) biofeedback can provide new information about users’ current internal states; (2) machine - driven feedback provides users with a future state or goal and leads to improved cohesiveness.

This paper reports on a study of 4CG, a cooperative enterprise located in rural Wales. 4CG operates for the good of the local economy and seeks to diversify its commercial portfolio through the creation of an online shop retailing goods and services from local suppliers. The paper compliments prior field studies focusing on rural enterprise and the challenges posed by this category of business for IT support. The current study is motivated by 4CG’s interest in setting up a local online shop and explicates the organisational issues that this venture turns upon and elaborates for broader sustainability agendas.

Participate was a 3-year collaboration between industry and academia to explore how mobile, Web and broadcast technologies could combine to deliver environmental campaigns. In a series of pilot projects, schools used mobile sensors to enhance science learning; visitors to an ecological attraction employed mobile phones to access and generate locative media; and the public played a mobile phone game that challenged their environmental behaviours. Key elements of these were carried forward into an integrated trial in which participants were assigned a series of environmental missions as part of an overarching narrative that was delivered across mobile, broadcast and Web platforms. These experiences use a three-layered structure for campaigns that draw on experts, local groups and the general public, who engage through a combination of playful characterisation and social networking.

The term Ubiquitous Monitoring aims to capture the unprecedented degree to which data collection will occur in the future through ongoing developments in embedded, wireless and sensory technologies. Intelligent buildings represent the most current instantiations of this technology in the form of building management/automation systems. However, there is an emerging field of research called adaptive architecture, which aims to explore more meaningful and direct interactions between occupants and their environments. In this paper, we use the experience of a prototype adaptive/biofeedback architecture called ExoBuilding as a probe to explore user attitudes towards future monitoring systems in buildings. We present results from a semi-structured interview, which encouraged participants to envision future monitoring technologies, making projections based on their real experiences with ExoBuilding.

Ethnographic studies have played a key part in informing the design and development of a multitude of ubiquitous systems, from control room systems to pervasive games. While other papers have often focused on systems developed for urban contexts, this paper presents the initial findings of a study that focuses on a rural produce market in West Wales as a site for ubiquitous multimedia system-based intervention, digital economic considerations and co-design. The findings relate to the initial ethnographic fieldwork, digital-economic considerations for the site, the evolution of a participatory design strategy for developing a Market Portal and - importantly -- the way that these are informing the design of the ubiquitous technologies relating to the Market Portal.

Our surroundings are becoming infused with sensors measuring a variety of data streams about the environment, people and objects. Such data can be used to make the spaces that we inhabit responsive and interactive. Personal data in its different forms are one important data stream that such spaces are designed to respond to. In turn, one stream of personal data currently attracting high levels of interest in the HCI community is physiological data (e.g., heart rate, electrodermal activity), but this has seen little consideration in building architecture or the design of responsive environments. In this context, we developed a prototype mapping a single occupant’s respiration to its size and form, while it also sonifies their heartbeat. The result is a breathing building prototype, formative trials of which suggested that it triggers behavioral and physiological adaptations in inhabitants without giving them instructions and it is perceived as a relaxing experience. In this paper, we present and discuss the results of a controlled study of this prototype, comparing three conditions: the static prototype, regular movement and sonification and a biofeedback condition, where the occupant’s physiological data directly drives the prototype and presents this data back to them. The study confirmed that the biofeedback condition does indeed trigger behavioral changes and changes in participants’ physiology, resulting in lower respiration rates as well as higher respiration amplitudes, respiration to heart rate coherence and lower frequency heart rate variability. Self-reported state of relaxation is more dependent on inhabitant preferences, their knowledge of physiological data and whether they found space to ‘let go’. We conclude with a discussion of ExoBuilding as an immersive but also sharable biofeedback training interface and the wider potential of this approach to making buildings adapt to their inhabitants.

Home networks have evolved to become small-scale versions of enterprise networks. The tools for visualizing and managing such networks are primitive and continue to require networked systems expertise on the part of the home user. As a result, non-expert home users must manually manage non-obvious aspects of the network - e.g., MAC address filtering, network masks, and firewall rules, using these primitive tools. The Homework information plane architecture uses stream database concepts to generate derived events from streams of raw events. This supports a variety of visualization and monitoring techniques, and also enables construction of a closed-loop, policy-based management system. This paper describes the information plane architecture and its associated policy-based management infrastructure. Exemplar visualization and closed-loop management applications enabled by the resulting system (tuned to the skills of non-expert home users) are discussed.

The Homework project has examined redesign of existing home network infrastructures to better support the needs and requirements of actual home users. Integrating results from several ethnographic studies, we have designed and built a home networking platform providing detailed per-flow measurement and management capabilities supporting several novel management interfaces. This demo specifically shows these new visualization and control interfaces (1), and describes the broader benefits of taking an integrated view of the networking infrastructure, realised through our router's augmented measurement and control APIs (2).

This paper presents the evolution of a tool to support the rapid prototyping of hybrid museum experiences by domain professionals. The developed tool uses visual markers to associate digital resources with physical artefacts. We present the iterative development of the tool through a user centred design process and demonstrate its use by domain experts to realise two distinct hybrid exhibits. The process of design and refinement of the tool highlights the need to adopt an experience oriented approach allowing authors to think in terms of the physical and digital "things" that comprise a hybrid experience rather than in terms of the underlying technical components.

Abstract Life sciences research is based on individuals, often with diverse skills, assembled into research groups. These groups use their specialist expertise to address scientific problems. The in silico experiments undertaken by these research groups can be represented as workflows involving the co‐ordinated use of analysis programs and information repositories that may be globally distributed. With regards to Grid computing, the requirements relate to the sharing of analysis and information resources rather than sharing computational power. The myGrid project has developed the Taverna Workbench for the composition and execution of workflows for the life sciences community. This experience paper describes lessons learnt during the development of Taverna. A common theme is the importance of understanding how workflows fit into the scientists' experimental context. The lessons reflect an evolving understanding of life scientists' requirements on a workflow environment, which is relevant to other areas of data intensive and exploratory science.

The Taverna e-Science Workbench is a central component of myGrid, a loosely coupled suite of middleware services designed to support in silico experiments in biology. Taverna enables the construction and enactment of complex workflows over resources on local and remote machines, allowing the automation of otherwise labour-intensive multi-step bioinformatics tasks. As the Taverna user community has grown, so has the demand for new features and additions. This paper outlines the functional requirements that have become apparent over the last year of working with domain scientists, along with the solutions implemented in both the Taverna workbench and the Freefluo enactment engine to address concerns relating to workflow construction and enactment, respectively

MOTIVATION: In silico experiments in bioinformatics involve the co-ordinated use of computational tools and information repositories. A growing number of these resources are being made available with programmatic access in the form of Web services. Bioinformatics scientists will need to orchestrate these Web services in workflows as part of their analyses. RESULTS: The Taverna project has developed a tool for the composition and enactment of bioinformatics workflows for the life sciences community. The tool includes a workbench application which provides a graphical user interface for the composition of workflows. These workflows are written in a new language called the simple conceptual unified flow language (Scufl), where by each step within a workflow represents one atomic task. Two examples are used to illustrate the ease by which in silico experiments can be represented as Scufl workflows using the workbench application.

My Grid is an e-Science Grid project that aims to help biologists and bioinformaticians to perform workflow-based in silico experiments, and help them to automate the management of such workflows through personalisation, notification of change and publication of experiments. In this paper, we describe the architecture of my Grid and how it will be used by the scientist. We then show how my Grid can benefit from agents technologies. We have identified three key uses of agent technologies in my Grid: user agents, able to customize and personalise data, agent communication languages offering a generic and portable communication medium, and negotiation allowing multiple distributed entities to reach service level agreements.
