In Brief

People create understandings and build relationships as they interact and communicate with one another. As agents in a sociotechnical world, we encounter one another ever more through mediating technologies. Our ability to act effectively depends on the extent to which we are able to engage with one another in technically constrained environments. This in turn affects our sense of belonging, manifestations of agreement, toleration of dispute, and recognition of mutual comprehension.

Physical action and human perception are intrinsically linked. In a social world, political action is similiarly conditioned by 'perceptions' of freedom, fairness and common good. Groups of actors communicate, coordinate and act in response to the opportunities and threats they collectively perceive around them.

Research

My research is concerned with the relationship between people and Information and Communication Technologies (ICTs). These technologies are all-pervasive in the industrialized world and have a huge presence in developing nations, especially amongst activist groups. My work examines how the design of interactive communications media (such as video-mediated communciation, instant messaging, email, web communities) help or hinder us in our efforts to understand one another, to create and resolve conflicts, and to cement relations in social groups.

In addition to research of this kind, I am also concerned with the science base for research on people and ICTs. That means I conduct projects with a methodological focus (finding new ways to find out new things). I am equally interested in methods whether they are quantitative (using numbers to describe and compare) and qualitative (using other observational data, especially linguistic information).

Research Ethics

I am the Research Ethics Officer for the Department of Computer Science. Some fields of CS research necessarily involve the participation of members of the public for testing and evaluation. It is this kind of research that must be scrutinised to ensure that ethical standards are met, as explained in a recent Times article. In such instances, the research must be planned so that rights and safety of participants (and research officers) are properly respected, and the activities they are asked to perform are properly explained. Ethical considerations apply to a wide range of institutional activity within the University of Bath. As a Research Ethics Officer, my role is to the provide guidance and awareness of ethics considerations in research to my colleagues and students. We use a self-checking scheme to help identify and manage ethical issues that may arise in CS research that involves public participation. For more information about what you should do to take into account the ethical issues that might affect your research, please see the Department of Computer Science Research Ethics page.

Teaching

My teaching is on the boundary between science and engineering and between computer science and psychology. In particular, it focuses on the connection between designing and evaluating ICTs through analytical processes that aim to understand ICT usage. Classes for 2009/10 will include Systems Engineering and Interaction for undergrads and Collaborative Systems for grad students.

The connection between my teaching and my science research is in understanding the relationship between the work we do as groups of people and what groups try to achieve aided by interactive technologies. We have to do work just to be able to understand, cooperate and integrate our separate efforts, besides the 'headline work' of the particular project itself. This is, in the end, how we are able to realise our individual potential. A recent interview with Chris Kingsley of Rebellion Games brings out a lot of these points in the context of computer games development.

Technologically Mediated Conversations and Relationships

There are lots of ways to talk through computers but the most familiar of all is probably email. Our everyday experience of email is one of mixed feelings. Email and SMS can be great. The are fast, convenient, easy to refer to, accessible from just about anywhere in the world. Unfortunately, their use can also be awkward and unpleasant. They can be too fast (replies can be sent too quickly), inconvenient (casual remarks are brought back to haunt us as promises), and has an unpredictable rhythm (batteries fail on a laptop, wireless goes down, the message recipient doesn't reply when expected).

Converstations always take place for a reason. Sometimes we engage in them for several reasons and sometimes the original reason is lost, or rather superceded, as our conversations take new twists and turns. My research considers how groups of people collaborate with one another, the way they articulate their understanding and concerns to one another, especially their 'stories', and depends upon knowledge of the spaces they inhabit and how they maintain their identities.

Tone and Emotional Force

Possibly the hardest thing of all about email is to judge the 'tone' of messages, or statements within messages. It is hard to do this because we don't get to see, for example, the smiles or the frowns that accompany the harsh black-and-white of text-on-screen.

Certainly, the loss of non-verbal signals is a part of the problem - even with the benefit of smilies ;-> The interpretation of what is meant by any message relies on an understanding of the conversation and also the relationship within which the conversation takes place. The tone of the conversation gives us grounds for reading the tone of a message.

It is hard to work within an environment that relies on email conversations and still stay in touch with the broader context of which they are a part. To work through email is in some sense to be act in a world that is detatched. Famously, an internal email memo, no doubt sent in haste and without reflection, read: It's a good day to bury bad news.

This message was sent at a time when, outside of the rarefied atmosphere of that organisation, and the ultra-rarefied atmosphere of email-in-haste, was absorbed in the horror of the 'bad news' itself.

So what is this 'tone'? It is the emotional force of the message as it is read. How often have you thought, when you have received an email: How Rude!. Or had an overly terse reply to an email that you have sent, that makes you ask yourself: Was I so very rude in what or how I wrote to them? There seems to be more scope in text-based communication for emotionally significant misunderstanding than when we speak on the phone or meet for real. It's hard to manage, on occasion, the yawning spaces between words. These occasions are nearly always when we have to deal with contentious matters. People do this by searching among a set of possible interpretations (or simply jumping for the first meaning that comes to mind). One way of thinking about this is that every message tells a story and the interpretations we are able to place on messages therefore depends upon the number of narratives we are able to use to make sense of them.

Contention is hard to manage through computer media

My current research is attempting to better understand what these matters are, how to recognise them, and how to better design communications media that can cope with them. It builds on prior work on how groups of people work together by drawing on their social and working environment, and by shaping their appearance and behaviour for others. One of the most productive ways to approach the problem is to take a social psychological perspective on the functioning of small groups. The research on small groups has provided many interesting and valuable insights into team working and organisation. For contention, or 'storming' as it is sometimes described, the best insights have come from two bodies of work, known as Social Identity Theory and Self-Categorization Theory.

Reasoning about Identity and Design of CMC Systems

Working with Dr Ahmad J Reeves, I have been working on an An Identity-based Design Framework for Computer-Mediated Communication Systems. This is an attempt to harness the insights that have come from this social psychological investigations to better understand:

how identity makes people think about CMC technologies in everyday settings
how the design of text-based CMC technologies might be improved to account for their practical concerns for managing their identity

Conflict, Conciliation and Mediating Technology

Mediation doesn't always mean that there are technologies standing between people and through which they therefore must communicate. There is a much longer history of 'medium' taking human form. Mediation is necessary to resolve disputes between people that have become so hostile or intractible that the parties can no longer communicate with one another effectively. This kind of mediation - the introduction of a third-party to act as a broker - can itself take many forms and is governed by a host of practice-based principles. Matt Billings is researching these principles to better understand:

what makes conciliating mediation effective given that parties have real difficulty in communicating with one another?
how the effects of computer-mediated communication might be described through a conciliating model?
the limits and value of introducing digital media to human mediation?

Presence and Empathic Communciation Online

Despite all the pitfalls of using CMC technologies, most people find them to be useful - even invaluable - most of the time. More than this, some people are unable to find value in communication other than through technologies. For such people, often facing severe and disabling personal challenges, CMC technologies like discussion groups and bulletin boards are something of a life line. But why is this? Convenience is an important factor, particularly when mobility is limited, but the ability to share highly unusual experiences is probably a bigger factor. There are many unanswered questions about the quality and value of interpersonal support through specialist online communities.

James Dove is investigating how people support one another, asking how people with particular problems are able to find benefit in communicating with one another online. He is considering:

what makes presence in online discussion groups seem so real, given that communication outside of these fora seems to be so hard?
are there dimensions of psychological vulnerability that render certain sorts of personal challenge more amenable to CMC support than others?
what might be understood from these very particular CMC interactions about highly empathic online interactions in general?
