Conference Paper
Poor indoor air quality (IAQ) can affect health and cognitive performance prior to users becoming aware of the declining air quality. Yet office occupants rarely have access to IAQ information upon which to base their ventilation decisions. This paper details the design and deployment of a situated IAQ display as a probe to explore ventilation and...

Our workshop brings together researchers interested in collecting a...
Article
Peer‐learning that engages students in multiple choice question (MCQ) formulation promotes higher task engagement and deeper learning than simply answering MCQ’s in summative assessment. Yet presently, the literature detailing deployments of student‐authored MCQ software is biased towards accounts from Science, Technology, Engineering, Maths and Me...
Conference Paper
Smart thermostats offer impressive scope for adapting to users’ thermal comfort preferences and saving energy in shared work environments. Yet human interactions with smart thermostats thus far amount to an assumption from designers that users are willing and able to provide unbiased data at regular intervals; which may be unrealistic. In this pape...
Article
This paper assesses the effect that the social structure of an office may have on an individual's behaviour with regards to their thermal comfort and indoor environment quality (IEQ). Combining the methodologies of Human Computer Interaction (HCI) and social sciences with indoor air research, semi-structured interviews were undertaken with 23 peopl...
Article
Full-text available
People with chronic musculoskeletal pain often experience pain-related fear of movement and avoidance behavior. The Fear-Avoidance model proposes a possible mechanism at least partly explaining the development and maintenance of chronic pain. People who interpret pain during movement as being potentially harmful to the organism may initiate a vicio...
Conference Paper
p>This paper details our work towards designing a system for crowd-sourcing responses on thermal comfort in naturally ventilated office buildings. We provide preliminary qualitative findings on the deployment of this system. Specifically, we explore the different human factors that led to our system being used as something akin to a digital complai...

Workplace interventions have shown beneficial results of resistance training for chronic pain in the neck, shoulder, and arm. However, studies have relied on experienced exercise instructors, which may not be an available resource at most workplaces. The objective of this study is to evaluate the technical performance level of upper limb rehabilita...
Conference Paper
Over-eating is often the result of consuming food for reasons other than needing fuel and nutrients: we eat for pleasure, from habit, for emotional support. Such non-homeostatic eating is an established contributor to overeating towards overweight or obese weight gain that in turn is correlated with numerous non-communicable diseases such as Type I...
Conference Paper
"Real sustainability will only be possible by consuming less." A ubiquitous computing path to consume less while improving health is to help us consume less processed food (60-70% of US/UK diet) in favor of whole food. The paper shows both the rationales for this focus and identifies key design challenges: interaction cycle, expertise and politics.
Conference Paper
Full-text available
Behavior modification in health is difficult, as habitual behaviors are extremely well-learned, by definition. This research is focused on building a persuasive system for behavior modification around emotional eating. In this paper, we make strides towards building a just-in-time support system for emotional eating in three user studies. The first two...

Article
As more applications move from the desktop to touch devices like tablets, designers must wrestle with the costs of porting a design with as little revision of the UI as possible from one device to the other, or of optimizing the interaction per device. We consider the tradeoffs between two versions of a UI for working with data on a touch tablet. O...
Conference Paper
Large numbers of Web sites support rich data-centric features to explore and interact with data. In this paper we present mashpoint, a framework that allows distributed data-powered Web applications to linked based on similarities of the entities in their data. By linking applications in this way we allow browsing with selections of data from one a...
Conference Paper
While previous research studied the high level attributes people consider when they assess the healthiness of food they are familiar with, little work has looked at how people assess arbitrary, potentially unfamiliar, food to decide whether it is a healthy choice. Since there is a growing body of work in Ubicomp around health practices, including s...
Article
Queries over large scale (petabyte) data bases often mean waiting overnight for a result to come back. Scale costs time. Such time also means that potential avenues of exploration are ignored because the costs are perceived to be too high to run or even propose them. With sampleAction we have explored whether interaction techniques to present query...
Article
Millions of recommendations, opinions and experiences are shared across popular microblogging platforms and services each day. Yet much of this content becomes quickly lost in the stream shortly after being posted. This paper looks at the feasibility of identifying useful content in microblog streams so that it might be archived to facilitate wider...
Article
Full-text available
We give away our data to multiple data services without, for the most part, being able to get that data back to reuse in any other way, leaving us, at best, to re-find, re-cover, retype, remember and re-manage this material. In this work in progress, we hypothesize that if we facilitate easy interaction to store, access and reuse our personal, soci...
Article
The movement to publish government data is an opportunity to populate the linked data Web with data of good provenance. The benefits range from transparency to public service improvement, citizen engagement to the creation of social and economic value. There are many challenges to be met before the vision is implemented, and this paper describes th...

The rise of "Web 2.0" has seen an explosion of web sites for the social sharing of personal information. To enable users to make valuable use of the rich yet fragmented sea of public, social, and personal information, data mashups emerged to provide a means for combining and filtering such information into coherent feeds and visualizations. In this...
Conference Paper
In CSCW, how much do we need to know about another domain/culture before we observe, intersect and intervene with designs. What optimally would that other culture need to know about us? Is this a "how long is a piece of string" question, or an inquiry where we can consider a variety of contexts and to explicate best practice. The goal of this panel...
Conference Paper
Full-text available
The popularity and plurality of social sharing and collaboration platforms today demonstrates the demand for sharing information at a wide variety of granularities and scale — from public blogging of micro-data (e.g., microblogging posts, page “Likes”, and place-“check-ins”) to specific, full-on collaborative sharing of documents and projects. The...

Conference Paper
Full-text available
Mainstream PIM tools capture only a portion of the information that people need to manage. Many information scraps seem to exist that don't make their way into these tools, instead being relegated to sticky notes, text files, and other makeshift storage, or simply being lost. In an effort to understand the role of these information scraps, the unde...
Conference Paper
One of the foremost challenges towards realizing a “Read- write Web of Data” [3] is making it possible for everyday computer users to easily find, manipulate, create, and pub- lish data back to the Web so that it can be made available for others to use. However, many aspects of Linked Data make authoring and manipulation difficult for “normal” (ie...
Conference Paper
Full-text available
Medicine, psychology and quality of life literature all point to the importance of not just asking 'how are you?', but assessing and being aware of self and others' well-being. Social networking has been shown to have a variety of uses and benefits, but does not currently offer explicit expression of a well-being state. We developed and deployed He...
Conference Paper
As being threatened by overweight and obesity, more and more people start thinking how to change the way they eat. However, less evidence shows current diet-related applications really work and current design mainly focuses on nutrition value and are not tailored to specific person.

Conference Paper
Are we in the semantic web/linked data community effectively attempting to make possible a new literacy - one of data rather than document analysis? By opening up data beyond the now familiar hand crafted Web 2 mash up of data about X plus geography, what are we trying to do, really? Is the goal at least in part to enable net citizens rather than o...

Efforts over the past decade to digitize scholarly musicological materials has revolutionized the research process, however online research in musicology is now held back by the segregation of data into a plethora of discrete and disparate databases, and the use of legacy or ad hoc metadata specifications that are unsuited to modern demands. Many r...
Article
Full-text available
In any domain, a key activity of researchers is to search for and synthesize data from multiple sources in order to create new knowledge. In many cases this process is laborious, to the point of making certain questions effectively intractable because the cost of the searches outstrip the time available to complete the research. As more resources a...
