I only have one big research question, but I attack it from a lot of different angles. The question is representation. How do people make, see and use things that carry meaning? The angles from which I attack my question include various ways in which representations are applied (including design processes, interacting with technology, computer programming, visualisation), various methods by which I collect research data (including controlled experiments, prototype construction, ethnographic observation), and the theoretical perspectives of various academic disciplines (including computer science, cognitive psychology, engineering, architecture, music, anthropology). If you are based in Cambridge, you may like to attend the following talks on human-computer interaction. This page lists a few large research themes and major projects illustrating them. Smaller projects, including contributions to research communities and research-related teaching, are described on my publications page, and other activities page. Crucible: Research in Interdisciplinary Design Crucible is the Cambridge network for research in interdisciplinary design, which I founded with David Good. The network encompasses very many projects, funding sources and collaborators. Crucible projects include practical design work (as commercial consultants or in academic contexts) that draws on multiple disciplinary perspectives. We also carry out a significant amount of design research - investigating the processes of design work, developing facilitation processes for design activity, informing public policy related to the design of public value from academic research, and creating new and experimental software tools for designers to use. Many of these projects draw on my core expertise in visual representation. Software and Creativity Many contemporary arts practitioners develop software, incorporate it into their work, or use software tools to extend their professional practice. This research theme involves collaboration with a wide range of artists, including many with international profiles, exploring the ways in which they use representations. We have created a wide range of new software tools and programming languages for composers, performers, choreographers, sculptors and others. Many of these projects are linked via the Crucible page. Social Media and Activism Internet technology research is crucially dependent on understanding the social dynamics of the ways in which it is used, and collaboration with social scientists is essential to provide intellectual rigor and new insights. These projects have investigated the design and deployment of new social media, both in the world at large (various professional and political contexts), and within the University itself. In all cases, the representation of social relations around and within technical systems has been critical to understanding and the development of new understanding among all stakeholders. Many of these projects are linked via the Crucible page. Energy Monitoring and Usage Electricity is invisible, so our awareness of environmental impacts arising from energy use is solely dependent on the quality of the visual representations provided of energy use. Ever since contributing to the design of the first generation of semi-smart domestic gas meters in 1991, I have taken an interest in the user interface of home energy controls and monitoring. Several of our projects are concerned with helping people understand and control the patterns of energy usage in their homes. Many of these projects are linked via the Crucible page.

I'm Professor of Design Theory in the School of Design at Northumbria University, which has roots back to 1844 as one of the original British Government Schools of Design. I'm an Interaction Designer who occasionally dabbles in product and service design. I have a multi-disciplinary background in humanities (History), applied human sciences (Education), and engineering design (Computer Science, old school HCI). In 2005 I was awarded a UK NESTA fellowship to work on value-centred approaches to design. As a first result, I moved beyond value (to worth) and beyond centredness (to multiple design foci). As a second result, my research has developed a more general design focus, and I moved from Computing (Sunderland) to Design (Northumbria) in September 2009. I now work alongside very talented design educators and researchers with a broad range of craft skills and design philosophies. I increasingly find the user-centred positions of 1980s HCI naive and uninformed. When I'm not supporting an amazing group of colleagues in my role as Associate Dean for Research and Innovation, my research focuses on balanced, integrated and generous (BIG!) fusions of the main design paradigms (Applied Arts, Engineering, User-Centred). Examples of such fusions include leveraging crafted forms within user research, focusing evaluation practices on achieved worth, combining engineering specification with humane design purposes, and blending tacit creative and explicit systematic design work. I have developed the Working to Choose (W2C) framework to provide an overarching structure for co-ordinating research on re-usable resources in design practice.

I am an interaction designer and researcher. I teach courses on interaction design, service innovation, design theory, and HCI methods. My research falls into four areas.Interaction with intelligent systems: I investigate how to blend human and machine intelligence. I’m also interested in how designers can more easily grasp machine learning as a design material. My current work include a decision support system that aids clinicians in deciding if they should implant an artificial heart.Designing for the Self: I apply product attachment theory (why people love their things) to the design of digital products and services. Many of the systems we have made help parents feel that they are becoming better parents. Examples include an alarm clock that keeps small children from waking their parents and a mobile system that learns a family's routines and alerts parents when they forget to pickup their kids. My current work investigates how changes to the form and behavior of digital things can make people experience them as more valuable.Public service innovation via social computing: I investigate how social computing can help citizens engage in the co-design of the public services they use. My current work includes Tiramisu, a deployed app that allows transit riders to crowdsource real-time arrival information.Research through design: I study how design inquiry, with its focus on exploring possible futures through a process of making things, can be integrated with scientific and engineering inquiry. Book: Design Research through Practice.Before joining the HCI Institute, I researched personalized TV systems for Philips Research.

Bob Spence is Professor Emeritus of Information Engineering at Imperial College London. Bob Spence's research has ranged from engineering design to human-computer interaction,and often with the manner in which the latter can enhance the former. Notable contributions, usually in collaboration with colleagues, include the powerful generalized form of Tellegen's Theorem; algorithms for improving the manufacturing yield of mass-produced circuits; and, in the field of Human-computer Interaction, the invention of the first focus+context technique, the Bifocal Display (aka Fisheye lens). The novel Attribute and Influence Explorers provide examples of novel information visualization tools that have wide application, including engineering design. Interactive computer graphics allows the electronic circuit designer to sketch the familiar circuit diagram on a computer display. This potential was pioneered by Bob and his colleagues in the late 1960s and eventually, in 1985, led to the commercially available MINNIE system developed and marketed by a company of which Bob was chairman and a founding director. More recently, Bob's research has focused on the topic of Rapid Serial Visual Presentation in which a collection of images is presented sequentially and rapidly to a user who may be searching for a particular image. This activity is similar to the riffling of a book's pages.

Dr. Tristan Henderson has been a Lecturer in Computer Science in the University of St Andrews since December 2006 and is now a senior lecturer. In 2011 he helped cofound SACHI and his research revolves around measuring communications networks and their users. His PhD looked at measuring networked game servers and game players, but more recently he has been investigating new methodologies for measuring mobile, wireless and online social networks and their users. He attempts to use the results of this network measurement to build more usable networks. Specifically networks which support the functionality that users desire. For instance we can use network measurement to improve security and privacy so that people can use pervasive sensor networks. Or we can measure network behaviour and use this to inform the design of future networks. He is one of the Workshop Organisers for Health, Wealth and Identity Theft: Designing and evaluating usable security and privacy mechanisms for online happiness a Workshop at the British HCI 2011 conference, and organised the Privacy and Usability Methods Pow-wow at British HCI 2010.
