The aim of this recently funded research project is to develop a principled HCI design approach for use in complex, safety critical environments. Specifically, the principles developed will be used to resolve common cognitive failures in the execution of flight-deck tasks. These principles will therefore contribute to lower rates of pilot error. In order to achieve this, existing work on Task Knowledge Structures (TKS) [Johnson P, Johnson H, Hamilton F, 2000] will be extended for application in safety critical interface design. This extension will involve the identification of common knowledge structures across multiple safety critical environments, including but not limited to the co-ordination and verification of instructions, error recovery and the updating of system state knowledge. Empirical studies will be used to investigate and evaluate both the principles and the resulting redesigns.
Information presentation and synthesis for system assessment IPSSA

Staff to be appointed
Configurable structured message systems (with Jean Dollimore, Sylvia Wilbur and George Coulouris)
This is where Hilary Johnson and I first developed the Task Knowledge Structures theory and methods.
We developed an initial framework of generalised task and interaction models in this project.
We investigated the use of algebraic and logic based specification of task and system models.
Here we investigated integrated multimedia communication and domain application software for group working in environmental planning.
This was an ESPRIT II Basic Research Action on "Interactive Dialogue models for explanation and learning". This research involved an important extension to TKS to handle fundamental task knowledge structures such as explanation, negotiation, etc. A TKS of how to provide explanations was produced. The project involved collaboration with City University, University of Pisa and University of the Aegean. Research staff: Dr. Hilary Johnson
The project investigated the methods of modelling group and organisational requirements for computer systems. Research staff: Christine Knowles.
John Samuel and Panos Markopoulos investigated novel graphical interaction for multiple planning and control tasks.
This project developed scenarios for the design of the next generation of European air traffic management workstations. This involved defining the user requirements for complex cognitive tasks on the ground and in the air. The research has applied the results of the ADEPT and the TOM projects to these problems. Research staff: Dr. Hilary Johnson, S.Gikas.
This project builds upon the earlier work on task knowledge structures (TKS) commenced under the ICL project. The research has made a significant advancement in developing a model-based approach to the design of user interfaces. The results have included a demonstration environment for constructing user interfaces using a variety of model-based tools. The industrial collaborators were British Aerospace, British Maritime Technology and MJC2. Research staff: Steph Wilson, James Pycock
The purpose of the research was to investigate how designers and users may participate in the design and development of interactive systems from the perspective of their intended usage. The research aimed to further the understanding of the software design process by focusing design on issues that effect how the system is to be used and its fitness for purpose. The work was based on research issues arising from earlier work on investigating and developing a user and task-based prototyping environment. Research staff: S.Wilson, M.Bekker, M.van de Kant
This project was designed to bring together disparate work on specification and prediction in the design of human-computer interfaces. The overall aim of the project was to enable work and domain oriented requirements to be applied to formal architectural models of user interfaces expressed in terms of a novel formulation of "interactors". The purpose of this is to enable the HCI designer to define and experiment with the architecture of the user interface (at an abstract level) while simultaneously investigating its temporal properties as they relate to task and domain requirements. The principle themes of the research are: (i) to refine the "interactor model" and develop its theoretical properties, (ii) to enable the derivation of formal expressions of domain and work oriented requirements that are applicable to an verifiable in interactor based architectural models of user interfaces, and (iii) to facilitate the use of these advances within practical HCI design through the development of prototype software tools.
This project investigated the use of TKS models as a communication between users and designers. A framework was produced for relating representations used in design, to the communication that occurs and the design activities that are required. An assessment was made of the benefits to be gained from using particular representations in specific communication and design activities to produce prescriptions for the use of representation in design. Research staff: Dr. E O 'Neill, A. Dickenson.
EPSRC funded project to investigate principle of user interface design based on task knowledge structures. The project takes as its starting point two implications of Task Knowledge Structures. First that the goal and procedural structures of tasks produce a causal relationship between activities that once established and learned affects human task performance. Furthermore, that this relationship has implications for the semantic and perceptual design properties of user interfaces. Second, the taxonomic object structure of task knowledge once established and learned also affects human task performance. The semantic and perceptual properties of user interfaces can and should be designed with this in mind. The research is carrying out theoretical, empirical and design studies to further develop these principles. The research project originated with the PhD work of Fraser Hamilton and currently Devendra Fakun was employed as the research member of staff.
The research aim is to provide a new integrated approach, (TICKS) based on (TKS) and (ICS), to model the social and communicative processes and knowledge, involved in multitasking and collaborative work tasks, undertaken in dynamically changing situations. We need to increase our understanding of modelling work tasks by considering how the activities of collaboration are themselves embodied in cognitive, social and contextual processes and phenomena. New situations of use indicate a need for individuals to work simultaneously on more than one task often in collaboration with other people, and in varying contexts and locations. This necessitates identifying user's task knowledge, the relationship between tasks and the mental effort required in executing tasks. Working on collaborative tasks means identifying group goals, and how they can be achieved whilst minimising individual and group mental effort. Communication between group members needs to be modelled as do the organisational and contextual constraints within which the tasks are to be performed. From an HCI perspective, it is necessary to identify user, group and task requirements for interactive systems to support multitasking and collaboration. This project is funded by the EPSRC for 36 months. The Bath team is lead by Dr. H. Johnson and Professor P. Johnson, and the Shefffield team is led by Dr. Jon May. Tim Gamble and Peter Wild are the Research Officers at Sheffield and Bath.
