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.

Abstract:
As the field of information visualization matures, researchers are able to reflect on, and perhaps even question, some long-accepted notions from the area. In this talk, I focus on three such notions:
* Representing network data through force-directed node-link diagrams
* Focusing on visual representation first and foremost
* Evaluating visualizations through user studies and experiments
Although these ideas clearly have value as evidenced by their acceptance and longevity, I have begun to question the wisdom of each. In this talk I’ll explain my concerns about these notions and I’ll suggest a new, alternative approach to each as well. To support these arguments, I will describe a number of research projects from my lab that illustrate and exemplify the new approach.

We are proud to announce that Dr David Harris-Birtill, leader of the SICSA Medical Imaging theme, is an invited speaker at the Collaboration Technologies and Systems conference (CTS 2015), held in Atlanta, Georgia from 1st – 5th June 2015.
He will be presenting a tutorial entitled ‘Improving patient care: zero-touch technologies in the clinical environment’ on Monday 1st June, which will explore the potential for remote sensing, interactive, and collaborative computational tools for the clinical environment.

The tutorial will discuss how zero-touch devices can improve interaction in surgical settings and how camera-based technology can be utilised in the clinic to monitor vital signs, speed diagnosis and improve the patient experience. It will cover an overview of how computation is used in the clinic, explaining the technologies used, the clinical workflow and how current scientific research can lead to future improvements in patient care.
The tutorial will also use a worked example, highlighting the uses of the Microsoft Kinect to discuss this technology’s potential, demonstrating how it can be used to collaboratively control selection of medical images in a surgical environment, showcasing its potential to monitor the patient’s heart rate and blood oxygenation level before, during, and after treatment.
Dr Harris-Birtill’s tutorial will cover the following topics:

• Background and history of technology in medicine.
• State of the art technology in healthcare, including collaborative and embedded systems.
• Worked example of gesture-based control, and monitoring of patients using the Microsoft Kinect and related technologies.

On lions, impala, and bigraphs: modelling interactions in Ubiquitous Computing.
<!–Speaker: Tom Rodden, University of Nottingham
Date/Time: 2-3pm May 19, 2015
Location: CS1.33a, University of St Andrews–>
Abstract:
As ubiquitous systems have moved out of the lab and into the world the need to think more systematically about how there are realised has grown. This talk will present intradisciplinary work I have been engaged in with other computing colleagues on how we might develop more formal models and understanding of ubiquitous computing systems. The formal modelling of computing systems has proved valuable in areas as diverse as reliability, security and robustness. However, the emergence of ubiquitous computing raises new challenges for formal modelling due to their contextual nature and dependence on unreliable sensing systems. In this work we undertook an exploration of modelling an example ubiquitous system called the Savannah game using the approach of bigraphical rewriting systems.
 
This required an unusual intra-disciplinary dialogue between formal computing and human- computer interaction researchers to model systematically four perspectives on Savannah: computational, physical, human and technical. Each perspective in turn drew upon a range of different modelling traditions. For example, the human perspective built upon previous work on proxemics, which uses physical distance as a means to understand interaction.
 
In this talk I hope to show how our model explains observed inconsistencies in Savannah and ex- tend it to resolve these. I will then reflect on the need for intradisciplinary work of this form and the importance of the bigraph diagrammatic form to support this form of engagement.

Workshop By Prof Sheelagh Carpendale and Dr Samuel Huron
Workshop Focus and Motivation
We are moving into a new era of a data driven society. The collection and use of data abounds in science, industry, government, commerce, and also in our personal lives both at work and socially. Data is being continually collected, and being stored in increasingly massive data warehouses in the expectation of later analysis and use. The common belief is that through this data, we, as a society, can gain new insights and learn how to run our lives, businesses, cities, etc. more efficiently, and effectively. Yet society is increasingly, if only vaguely aware of the volume and variety of data that we are accruing on a daily basis. However, there is a gap, how can data lead to new insight?
To realise even the beginning of the promised potential of this data, we must become data literate. To be an effective data driven society this notion of data literacy must extend beyond the data literacy of a few experts to a wider population. We must each become, at least somewhat, data literate.
To test the waters of what might possibly constitute data literacy exercises, we will hold a workshop based on sketch based visualisation and constructive visualisation on May 8^th 2015.
This will be a hands-on workshop where we will conduct exercises on data characterisation, visualisation data sketching, and constructive visualisation. There will be several short talks on basic data visualisation concepts, discussions, sketching sessions and constructive visualisation sessions.
In this workshop you employ the basic visual variables to construct meaningful representations, the dynamic manipulation of spatial positioning to enable spatial reasoning, and through these practices you will become aware of the wide variety of ways that people can think about data.
This workshop is designed for professionals, academics, and anyone with an interest in visualisation and data science. No programming experience required.
