Johnson, Chris (1999): Why Human Error Modeling has Failed to Help Systems Development. In Interacting with Computers, 11 (5) pp. 517-524.

“Until the 1980s, human reliability analysis focused upon individual erroneous actions. More recently, attention has shifted to the managerial and organizational contexts that create the latent conditions for such failures. Unfortunately, these developments have had little impact upon many industries. The problems of technology transfer are less due to commercial neglect than to the failure of human-factors' research to seriously consider the problems of systems development. For example, most error-modeling techniques are poorly documented. In consequence, errors are likely to be made when designers apply error modeling techniques. There are further ironies. Many of these techniques depend entirely upon the skill and intuition of human factors' experts. The lack of professional accreditation procedures prevents companies from assessing the quality both of those experts and their advice. Until these practical problems are addressed, increasingly esoteric models of human and organizational failure will be of little practical benefit. Over the last 5years, a number of researchers have become increasingly concerned to support technology transfer between human error modeling and constructive systems development [1]. As a result, workshops were staged in Glasgow (1997), Seattle (1998) and Liege (1999). This special edition presents a collection of papers from these meetings.”

Johnson, Chris (1998): Representing the Impact of Time on Human Error and Systems Failure. In Interacting with Computers, 11 (1) pp. 53-86.

“Time plays a central role in our understanding of human 'error' and system 'failure'. Without a detailed knowledge of the flow of events, investigators cannot hope to arrive at well founded conclusions about the causes of major accidents. This paper argues that formal and semi-formal notations can be used to build time-lines that show the ordering of events leading to a failure. These time-lines help to improve the quality of an accident report by identifying the temporal inconsistencies that often arise between human factors and system engineering accounts of the same accident. This, in turn, can help to ensure that any recommendations for the future design of interactive systems are based upon coherent accounts of previous failures.”

Proceedings of the Thirteenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XIII August 1-4, 1998, Sheffield, UK. pp. 327-338.

“For the last twenty years, human-computer interfaces have been dominated by two-dimensional interaction techniques. Things are changing. Techniques that were previously restricted to specialized CAD/CAM tools and immersive VR systems are now being extended to the mass market. The photo-realistic facilities offered by QuicktimeVR and the model based renderings of VRML (Virtual Reality Mark-up Language) provide sophisticated tools for interface design. As a result, three dimensional visualization techniques are being widely exploited in the financial services industry, airports and even off-shore oil production. In January 1997, there were some 2,000 VRML models on the web. By January 1998, this number had grown to over 20,000. Research in human-computer interaction has, however, lagged behind these developments. Few guidelines can be applied to support the design of desktopVR. This paper, therefore, describes three criteria that can be applied to assess the usability of these interfaces. We then go on to validate these criteria against a number of case studies. Unfortunately, it is concluded that standard measures of task performance, successful navigation and subjective satisfaction cannot easily be applied to assess the utility of 3D systems.”

Johnson, Chris and Dunlop, Mark D. (1998): Subjectivity and Notions of Time and Value in Interactive Information Retrieval. In Interacting with Computers, 10 (1) pp. 67-75.

“"Time is money", especially if you are downloading web pages over low-bandwidth telephone lines. All too often this investment goes unrewarded. Users simply cannot extract relevant information from the mass of data that is being provided over the Internet. This information saturation is exacerbated by the problems of electronic gridlock. The increasing demand for remote resources has led to increasing delays during peak periods on popular sites. This paper argues that, in the short term, technological solutions to these problems will not keep pace with the exponential growth in demand. The world's communications infrastructure cannot be improved at the rate that would be required to combat increasing retrieval delays. We, therefore, advocate interface design techniques as the only effective means of addressing the usability problems that frustrate interaction with Internet resources. Later sections introduce a central argument that links the papers in this special edition. Collaborative approaches to information retrieval, where search engines are augmented by advice from human experts, can reduce the problems of electronic gridlock and information saturation.”

Proceedings of the Twelfth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XII August, 1997, Bristol, England, UK. pp. 175-190.

“Recent improvements in the quality and reliability of wireless communications has led to the development of a range of mobile computing devices. Many portable computers now offer modem connections through cellular and satellite telephone networks. Taxi services, emergency vehicles, domestic repair teams all now rely upon mobile links to central computing systems. In spite of these advances, a number of technical problems still affect the quality of interaction with mobile applications. Electromagnetic interference blocks radio signals. Obstacles in the line of sight can interrupt microwave and infra-red transmissions. Tracking problems frustrate the use of low-level satellites. Transmission delays affect the service provided by higher, geostationary satellites. From the users' point of view, these problems manifest themselves as geographical constraints upon the usability of their 'mobile' device. This lead to delays in the transmission of critical information. These, in turn, lead to the frustration and error that often complicates the operation of mobile computer systems. In the short term, it seems unlikely that the technical limitations will be resolved. The following pages, therefore, argue that interface designers must consider means of reducing the impact of geographic allocation upon the operation of mobile computing devices.”

Proceedings of the Twelfth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XII August, 1997, Bristol, England, UK. pp. 191-204.

“This paper argues that marginal utility can be extended from the domain of Micro-economics to explain some of the problems that frustrate interaction with distributed systems. In particular, it is argued that concave utility curves can be used to analyse the electronic gridlock that occurs when remote systems cannot satisfy the number of demands which users make upon their services. Convex utility curves represent the information saturation that occurs when users cannot extract important documents from amass of irrelevant information. The paper goes on to argue that marginal utility can also be used to identify a range of interface techniques that reduce the problems associated with electronic gridlock and information saturation.”

Love, Lorna and Johnson, Chris (1997): Using Diagrams to Support the Analysis of System 'Failure' and Operator 'Error'. In: Thimbleby, Harold, O'Conaill, Brid and Thomas, Peter J. (eds.) Proceedings of the Twelfth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XII August, 1997, Bristol, England, UK. pp. 245-261.

“Computers are increasingly being embedded within safety systems. As a result, a number of accidents have been caused by complex interactions between operator 'error' and system 'failure'. Accident reports help to ensure that these 'failures' do not threaten other applications. Unfortunately, a number of usability problems limit the effectiveness of these documents. Each section is, typically, drafted by a different expert; forensic scientists follow metallurgists, human factors experts follow meteorologists. In consequence, it can be difficult for readers to form a coherent account of an accident. This paper argues that fault trees can be used to present a clear and concise overview of major failures. Unfortunately, fault trees have a number of limitations. For instance, they do not represent time. This is significant because temporal properties have a profound impact upon the course of human-computer interaction. Similarly, they do not represent the criticality or severity of a failure. We have, therefore, extended the fault tree notation to represent traces of interaction during major failures. The resulting Accident Fault Tree (AFT) diagrams can be used in conjunction with an official accident report to better visualise the course of an accident. The Clapham Junction railway disaster is used to illustrate our argument.”

Johnson, Chris (1996): Documenting the Design of Safety-Critical, User Interfaces. In Interacting with Computers, 8 (3) pp. 221-239.

“A number of techniques have been developed to map out the 'design space' of interactive systems. For instance, design rationale notations represent the various options that must be considered during interface development. Such notations offer important benefits. For instance, they can be shown to regulatory authorities to demonstrate that sufficient attention has been paid to particular design issues. Unfortunately, these notations are semi-formal. This leads to a number of weaknesses. They cannot be used to determine whether criteria and options have been used consistently during the development of an interactive system. Nor do they provide any procedures to determine whether interface design decisions have indeed been guided by a rationale. These are important limitations when regulatory authorities, such as the UK Health and Safety Executive, expect designers to demonstrate the consistency and coherence of their decisions. This paper addresses these problems and shows how decision theory can be employed to support design rationale during the development of human computer interfaces for safety-critical systems.”

“In July 1995, a workshop on 'Temporal Aspects Of Usability' was organised at the University of Glasgow. This was intended to provide a common forum for researchers in this area. The following contributions were submitted as position papers for this workshop. They fall into three broad themes.”

Johnson, Chris and Gray, Philip D. (1996): Assessing the Impact of Time on User Interface Design. In ACM SIGCHI Bulletin, 28 (2) pp. 33-35.

“Temporal properties of interaction have a profound impact upon the usability of human computer interfaces. Delays in response time can lead to frustration and error. The simultaneous presentation of many different pieces of information imposes heavy demands upon the cognitive and perceptual resources of system operators. These problems have been investigated by a number of recent research initiatives. Unfortunately, it has been difficult to replicate the results that have been obtained from experimental investigations. This creates significant problems for designers if these results are to guide the future development of interactive systems. This paper briefly describes how an multi-disciplinary team has addressed this problem during the Temporal Aspects of Usability (TAU) project.”

Proceedings of the Tenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers X August, 1995, Huddersfield, UK. pp. 39-50.

“New groups of users are learning to exploit the facilities provided by Internet browsers, such as Mosaic and Netscape. The graphical interaction style supported by these systems eases the traditional burdens of information retrieval using methods such as the file transfer protocol (ftp). In consequence, distributed information sources are being made available to people whose interests do not lie solely in computer science or systems engineering. This rapid growth in the Internet has exposed users to interaction problems that rarely occur with stand-alone computer systems. In particular, people are often faced with unpredictable timing delays over remote networks. These delays lead to frustration and error which can, in turn, prevent users from successfully retrieving necessary information. This paper exploits Clarke&Emerson's Computation Tree Logic (CTL) to identify presentation techniques that can support retrieval tasks. It is argued that CTL provides a convenient means of representing and reasoning about temporal properties of interaction with distributed systems.”

Proceedings of the Ninth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers IX August 23-26, 1994, Glasgow, Scotland, UK. pp. 285-297.

“Many safety-critical applications rely upon complex interaction between computer systems and their users. When accidents occur, regulatory bodies are called upon to investigate the causes of user 'error' and system 'failure'. Reports are drawn up so that the designers and operators of future systems will not repeat previous 'mistakes'. These documents present the work of specialists who are drawn from many different technical disciplines: human factors; forensic investigation; engineering reconstruction; computer simulation; etc. The findings of these different experts are often separated into different sections. This creates a number of problems. Important evidence can be hidden within numerous appendices. The interaction between systems and users can be obscured by tortuous cross referencing schemes. There are occasional temporal ambiguities and inconsistencies between the different analyses. This paper presents ways in which formal methods can be exploited to address these problems. Mathematical notations provide means of representing and reasoning about the circumstances that lead to accidents in human machine systems. Executable logics can also be used to simulate event sequences. These simulations might be shown to other analysts. They can be used to encourage agreement on the course of events prior to more detailed investigations.”
