Abstract
For many of us, interacting with data on mobile devices such as phones and tablets is commonplace in our lives, e.g. phone call data, TV guide, maps, fitness and wearable data. With the introduction of smart watches, the screen size of mobile devices has dramatically decreased. This reduction in screen real estate provides challenges for the design of interfaces, including the presentation and exploration of data visualisations. Using bar charts as an example, this presentation will explore the shortcomings of current zooming techniques on very small screens and consider proposed guidelines for the development of simple data exploration applications. Key design features such as the need for overview and context will be considered in respect to a simple and effective data exploration task.

Abstract:
Most of us might agree that ‘hands-on learning’ is good for children in the early years. But why? Is it simply more fun and sociable, or are there any more direct cognitive benefits? And what determines definitions of ‘hands-on’? Can we include iPads? This talk will draw upon an ESRC-funded project to examine the educational implications of recent theoretical arguments about the embodied nature of cognition. Video data from the project will be used to illustrate the methodological significance of the way children gesture when describing mathematical concepts and evaluate a hypothesis that numerical development is grounded upon two particular embodied metaphors. If correct, this presents a serious challenge to traditional approaches to the types of learning materials we offer children. The talk then demonstrates two embodied technologies to consider the potential of new forms of digital interaction to further our understanding of embodied cognition as well as support early learning.

Dr Andrew Manches is a Chancellor’s Fellow in the School of Education and leads the Children and Technology group at the University of Edinburgh. He has 20 years experience working with children, first as a teacher, then as an academic. His recent research, funded by an ESRC Future Research Leader grant, focuses on the role of interaction in thinking, and the implications this has for early learning and new forms of technology. When not being an academic, Andrew is a parent of two young children and directs an early learning technology start-up that was awarded a SMART grant this year to build an early years maths tangible technology.

In October 2015 we attended two IEEE conferences in the USA. Daniel Rough presented a full paper at the IEEE Symposium on Visual Languages and Human-Centric Computing, October 18–22, in Atlanta, Georgia. Uta Hinrichs presented a full paper at the IEEE Information Visualization (InfoVis) conference as part of VizWeek, October 25-30 in Chicago, Illinois. You can find details of these and all our papers on the publications page.
On November 10th, Daniel and Uta will reprise their talks here in St Andrews and everyone is welcome to attend. You can find the details for the two talks below along with links to the papers via the University of St Andrews research portal.

Abstract:
Conflicts occur in the peer-production process of Wikipedia and can culminate in “edit wars” for specific topics. This talk will present visualizations of the similarities and differences between the most controversial topics that have been identified in 10 different language versions of Wikipedia and discuss the dominant and shared themes of the controversies across languages and cultures. In addition, it will present visualizations of the most popular topics over time in the English version of Wikipedia and visually analyze the relationship between most controversial and popular topics.

Abstract:
Patients now generate a significant amount of online material about health.  This raises questions about how we should design websites featuring patient knowledge and experience in order to ensure those sites provide a good match to patient needs.  In this presentation I describe a structured participatory methodology for the development and evaluation of a set of patient experience websites that took place over three phases, consistent with experience based co-design:  (1) a capture phase in which we worked with patients to understand their reactions to existing websites; (2) an understand phase in which we translated this information into a patient-engagement framework and accompanying set of design guidelines and (3) an improve phase, where we used these guidelines to create three new health websites that were then assessed as patient experience interventions in a range of empirical studies.   MORE

Abstract:
Today, many web services personalize their content, including Netflix (movie recommendations), Amazon (product suggestions), and Yelp (business reviews). In many cases, personalization provides advantages for users: for example, when a user searches for an ambiguous query such as “router,” Amazon may be able to suggest the woodworking tool instead of the networking device. However, personalization is rarely transparent (or even labeled), and has the potential be used to the user’s disadvantage. For example, on e-commerce sites, personalization could be used to manipulate the set of products shown (price steering) or by customizing the prices of products (price discrimination). Unfortunately, today, we lack the tools and techniques necessary to be able to detect when personalization is occurring, as well as what inputs are used to perform personalization.
In this talk, I discuss my group’s recent work that aims to address this problem. First, we develop a methodology for accurately measuring when web services are personalizing their content. While conceptually simple, there are numerous details that our methodology must handle in order to accurately attribute differences in results to personalization (as opposed to other sources of noise). Second, we apply this methodology to two domains: Web search services (e.g., Google, Bing) and e-commerce sites (e.g., BestBuy.com, Expedia). We find evidence of personalization for real users on both Google search and nine of the popular e-commerce sites. Third, using fake accounts, we investigate the effect of user attributes and behaviors on personalization; we find that the choice of browser, logging in, and a user’s previously content can significantly affect the results presented.

Abstract:
Centuries ago, the technology of movable type vaulted human consciousness and expression from oral performance—improvisational— to writing, fixed by letters and words. The Interface Ecology Lab investigates new technologies that transform human expression. We engage the human body with the digital. We use cloud and web to maximize impact. We investigate how curation, exploration, and body-based interaction support expression and ideation. MORE

Abstract:
Mental illness is one of the greatest social and economic challenges facing our society.
The talk will consider at some of the different ways in which technology (and HCI research) can help, with a particular focus on the problem of engagement. Taking examples from a series of projects to develop novel technologies for use in the mental health space, we will see some of the unique issues and challenges which come from working in this domain, and the steps which can be taken to address them. The SilverCloud platform, designed to deliver range of engaging and effective clinician-supported mental health interventions, will be used as a specific example to discuss the topics of evaluation and dissemination. Development of a suite of programmes and a number of partnerships based on the platform have enabled the delivery of supported online interventions to tens of thousands of patients in a range of public and private healthcare services worldwide.

He is interested in design for specific application areas, and has led a number of interdisciplinary projects in a number of different domains. A major focus of his work over the last decade has been on the design of technologies for mental health. The aim has been to develop systems which can increase access to, increase engagement with, and assist in improving the outcomes of mental health interventions.
