projects such as EQUATOR, Smart-Its and Guide. Our research focus is in areas such as context-aware mobile systems (Davies, Cheverst, Friday) and situated public displays (Cheverst, Davies, Friday), which led to some of the first longitudinally deployed public Ubicomp experiments. Our work on wireless embedded systems for Ubicomp addresses the challenge of self- and relative-localisation using ultrasound and ultra-wideband (Hazas), activity recognition (Gellersen, Kortuem), environmental informatics (Marshall) and actuator networks (Finney). We are well known for our innovative mobile experience design through the creation of novel applications supported by Forum Nokia (Coulton).
Software Systems Engineering
Prof A Rashid, Prof J Whittle, Dr L Blair, Dr G Kotonya, Dr J Lee, Dr. J Mariani, Dr P Sawyer, Dr P Rayson
The School is an internationally leading centre for research on software engineering, particularly in requirements engineering (Sawyer), model-driven development (Whittle), aspect-oriented development (Rashid), component based software engineering and product lines (Lee, Kotonya), and for well-known work on natural language analysis (Rayson). Our research is driven by a set of fundamental long-term grand challenges pertaining to taming the complexity of software systems. These include compositionality: how to build and reason about systems built from parts that have emergent properties; evolution: anticipating and managing change and building systems that are resilient or embrace it; non-functional properties: how to model, predict and reason about non-functional properties; and, evaluation: how to provide evidence for the utility of software
engineering techniques and bridge research and practice. The School is unique in its cross-disciplinary approach to solving problems in software engineering. The Isis project, for example, unites software engineering with social sciences, ethics and corpus linguistics to provide a language modelling toolkit to identify paedophiles posing as children in online chat rooms in collaboration with specialist UK law enforcement agencies (Rayson, Rashid).
Cooperative and Interactive Systems Prof A Dix, Prof H Gellersen, Dr K Cheverst, Dr M Rouncefield, Dr G Kortuem, Dr J Mariani, Dr C Sas, Dr P Coulton
We are exploring the way humans interact with computers and also the way human-human interactions are affected by technologies. As part of this, we have established a strong international reputation for our expertise in analysis and design methods (Dix, Sas) and social and ethnographic analysis, particularly for investigating collaborative work (Rouncefield). We design and construct novel software and devices including interaction with virtual environments (Mariani), wearable computers (Kortuem) and even using physiological measurements (Dix). We have conducted extensive work on novel user interface technologies with mobile devices (near-field, mobile projection) (Coulton), steerable camera-projector systems and interactive surfaces (Gellersen). Very often these are in longitudinal deployments ‘in the wild’ – naturalistic use is very different to demonstrations in the laboratory. One example of this is the use of electronic doorplates for leaving digital post-it notes that is now deployed to 40 offices giving invaluable insights into the way people use new technology.
