Abstract:
Augmentative and alternative communication (AAC) attempts to augment natural speech, or to provide alternative ways to communicate for people with limited or no speech. Technology has played an increasing role in AAC. At the most simplest level, people with complex communication needs (CCN) can cause a prestored message to be spoken by activating a single switch. At the most sophisticated level, literate users can generate novel text. Although some individuals with CCN become effective communicators, most do not – they tend to be passive communicators, responding mainly to questions or prompts at a one or two word level. Conversational skills such as initiation, elaboration and story telling are seldom observed.
One reason for the reduced levels of communicative ability is that AAC technology provides the user with a purely physical link to speech output. The user is required to have sufficient language abilities and physical stamina to translate what they want to say into the code sequence of operations needed to produce the desired output. Instead of placing all the cognitive load on the user, AAC devices can be designed to support the cognitive and language needs of individuals with CCN, taking into account the need to scaffold communication as children develop into adulthood. A range of research projects, including systems to support personal narrative and language play, will be used to illustrate the application of Human Computer Interaction (HCI) and Natural Language Generation (NLG) in the design and implementation of electronic AAC devices.

Abstract:
In this talk I review examples from industry engagement activity that have taken well known theory in cognitive science and used them to address common HCI problems by forming new questions that have in turn lead to interface development. In the first part of the talk I discuss how a multi-disciplinary team including input from computer arts, computer games programming, engineering and psychology developed a multi-touch application to visualise financial planning targets on a Microsoft Surface. In the second part of the talk I will discuss how assistive agents displaying deictic gaze cuing have been implemented and evaluated using touch screen displays and eye-movement recording equipment. Both examples demonstrate how a practice-based approach to animation and an appreciation of vision science contribute to the understanding and development of intuitive interface design and implementation. The critical feature is the development of authentic animation conforming to the artistic principles of animation and the biological limits of the human visual system.

Abstract:

Previous work in eco-feedback has focused either on new sensing technologies, or on people’s responses to specific feedback devices and other interventions placed in their homes. We attempt to take a comprehensive approach based on a large scale deployment of off the shelf sensors coupled with face to face interviews to account for both the amount of energy that specific appliances draw upon, and what occupant practices rely upon the services provided by these appliances. We performed a study in four student flats (each with 7–8 occupants) over a twenty-day period, collecting data from over two hundred sensors and conducting interviews with 11 participants. We build an account of life in the flats, and how that connects to the energy consumed. Our goal is to understand the challenges in accounting for both resources and practices at home, and what these challenges mean for the design of future feedback devices and interventions aimed at reducing energy consumption. In this talk we share results of our recent analysis and our experiences of conducting Ubicomp deployments using off the shelf sensors to study energy use.

Abstract:
The cultural significance of Informatics is that it provides new forms of digital embodiment which lead to evolution of practices and meaning.
Engagement of Informatics with Design is a key approach to explore this relationship between technology and culture. This talk outlines how such an approach was developed over an extended period of engagement with the Arts and Humanities and Practitioners in the Digital Creative Industries.
Two projects in particular are used to illustrate this process Tacitus and Spellbinder.
Tacitus was a major AHRC/EPSRC project which explored tacit knowledge in designers and makers and how this could be support by computer design systems.
A novel haptic design system was developed which demonstrated significant improvements in ease of use.
Spellbinder was a new form of mobile application based on image matching using camera phones. Funded by the “Designing for the 21st Century” AHRC/EPSRC initiative we explored the potential of this new medium through an iterative series of workshops, intense design interventions and reflection which we termed Research by Design.

Title: Using Situation-Specific Models of Colour Differentiation to Assist Individuals with Colour Vision Deficiency
Abstract:
Approximately 10% of the world’s population experiences either congenital, acquired, or situationally-induced colour vision deficiency (CVD – commonly called colour blindness). People with CVD often confuse colours that those without CVD can distinguish. When working in digital environments, CVD can lead to problems ranging from minor nuisances (e.g., being unable to distinguish ‘visited’ from ‘not visited’ links on a webpage) to major safety concerns (e.g., not seeing colour-coded warning messages).
Recently, recolouring tools have been developed that modify the colours presented on a display to eliminate the colour confusion that people with CVD experience. However, these tools are limited to individuals with dichromatic CVD – a particularly severe and somewhat rare form of congenital CVD. As a result, individuals with acquired and situationally-induced CVD as well as those with non-dichromatic forms of congenital CVD continue to have difficulties.
In this talk, I will present my PhD research toward a new recolouring tool based on situation-specific models of colour differentiation. I will first present my work on situation-specific models that capture the colour differentiation abilities of any individual in any environment through a two-minute in-situ calibration procedure. I will then discuss my most recent work on developing a recolouring tool based on situation-specific models of colour differentiation.
About David:
David Flatla is a PhD student at the University of Saskatchewan in Canada under the supervision of Dr. Carl Gutwin. His research focusses on the field of accessibility, particularly on how to help individuals with colour vision deficiency (CVD – commonly called colour blindness). To do this, he invented situation-specific models of colour differentiation that utilize in-situ calibration to accurately capture how people differentiate colors. He publishes at conferences like CHI and ASSETS. At UIST this year, he presented research exploring how to make boring calibrations fun by turning them into games.

Abstract:
Our daily activities are continuously mediated by the space that we occupy; we face people to talk to them, sit in circular arrangements for group discussions, and write documents facing monitors. However, current interfaces generally make strong assumptions about where we are (e.g., monitors assume we are perpendicular and in front) or outright ignore important aspects of our spatial environments (e.g., several people editing a document). In my research I deal with the perceptual, cognitive and social aspects of space relationships that will shape the design of next generation interfaces. In this talk I will discuss projects that address questions such as: what happens when you look at a display from the “wrong” place? What forms of input are most efficient to interact with displays from different locations? How does having a private display affect our awareness of the work of others?

Abstract:
Our bodies shape our experience of the world, and our bodies influence what we design. How important are the physical differences between people? Can we model the physiological differences and use the models to adapt and personalize designs, user interfaces and artifacts? Within many disciplines Digital Human Models and Standard Observer Models are widely used and have proven to be very useful for modeling users and simulating humans. In this paper, we create personalized digital human models of perception (Individual Observer Models), particularly focused on how humans see. Individual Observer Models capture how our bodies shape our perceptions. Individual Observer Models are useful for adapting and personalizing user interfaces and artifacts to suit individual users’ bodies and perceptions. We introduce and demonstrate an Individual Observer Model of human eyesight, which we use to simulate 3600 biologically valid human eyes. An evaluation of the simulated eyes finds that they see eye charts the same as humans. Also demonstrated is the Individual Observer Model successfully making predictions about how easy or hard it is to see visual information and visual designs. The ability to predict and adapt visual information to maximize how effective it is is an important problem in visual design and analytics.

Title: Touch the Map: Making Maps Accessible for the Blind
Abstract:
Human navigation is a very complex phenomenon that mainly relies on vision. Indeed, vision provides the pedestrian with landmarks and dynamic cues (e.g. optic flow) that are essential for position and orientation updating, estimation of distance, etc. Hence, for a blind person, navigating in familiar environment is not obvious, and becomes especially complicated in unknown environments. Exploration of geographic maps at home (for travel preparation) or even on mobile phones (for guidance) may represent valuable assistance. As maps are visual by essence and hence inaccessible for the blind, multimodal interactive maps undoubtedly represent a solution. Multimodal interactive maps are based on a combination of multi-touch devices and tactile (e.g. embossed) paper maps. However, design and realization of interactive maps for the blind imply several challenges, as for example making multi-touch surfaces accessible for the blind. In this talk the concept and design of the maps, the work with the blind users, the technical challenges as well as the psychological background will be presented.
About Anke:
Anke Brock is currently a PhD candidate in Human-Computer Interaction at the IRIT research lab in Toulouse (France). She has worked several years as a research engineer for navigation and driver assistance systems at Bosch in Hildesheim (Germany).

Abstract:
In natural and social sciences, novel insights are often derived from visual analysis of data. But what principles underpin the extraction of meaningful content from these visualisations? Abstract data visualisation can be traced at least as far back as 1801; but with the increase in the quantity and complexity of data that require analysis, standard tools and techniques are no longer adequate for the task. The ubiquity of computing power enables novel visualisations that are rich, multimodal and interactive; but what is the most effective way to exploit this power to support analysis of large, complex data sets? Often, the lack of fundamental theory is pointed out as a central ‘missing link’ in the development and assessment of efficient novel visualisation tools and techniques.
In this talk, I will present some first steps towards the theory of visualisation comprehension, drawing heavily on existing research in natural scene perception and reading comprehension. The central inspiration is the Reverse Hierarchy Theory of perceptual organisation, which is a recent (2002) development of the near-centennial Laws of Gestalt. The proposed theory comes complete with a testing methodology (the ‘pop-out’ effect testing) that is based on our understanding of the cognitive processes involved in visualisation comprehension.
