Abstract 10 years ago, Castellani et al. (Journal of Computer Supported Cooperative Work, vol. 18, no. 2–3, 2009, pp. 199–227, 2009) showed that using just an audio channel for remote troubleshooting can lead to a range problems and already envisioned future in which augmented reality (AR) could solve many these issues. In the meantime, AR technologies have found their way into our everyday liv...

The ability to reflect contextual factors is crucial to the success of computerized support systems. Consequently, identifying how context affects the supported processes is a prerequisite for developing such systems, and ethnographic studies can play an important role in shaping system design. We are developing methods for supporting distributed collaborative troubleshooting by aiding the tran...

When working remotely with physical objects obvious problems of reference arise because of the lack of a mutually shared object. Systems aiming to support such work tend to be based on understandings of face-to-face interaction and frequently use video. However, video introduces new interactional problems. This paper describes a field study of remote interaction around objects that is telephone...

Society is demanding larger and more complex information systems to support increasingly complex and critical organisational work. Whilst troubleshooting socio-technical issues in small-to-medium scale situations may be achievable using approaches such as ethnography, troubleshooting enterprise scale situations is an open research question because of the overwhelming number of socio-technical e...

Most failures of linear electron accelerators (LEA) are caused by malfunctions in the systems of RF-feeding, modulators and clystrons. And a great part of malfunctions lead to the increased dispersion of amplitudes of output signals of the system. In this paper we consider the algorithms of failure prediction based on some indication functions and the use of these algorithms in the LEA control ...

Online discussion forums and community question-answering websites provide one of the primary avenues for online users to share information. In this paper, we propose text mining techniques which aid users navigate troubleshooting-oriented data such as questions asked on forums and their suggested solutions. We introduce Bayesian generative models of the troubleshooting data and apply them to t...

The maintenance of equipment, machinery and facilities is a vital part of the industrial process and requires millions of man-hours of technician time. A significant portion of this time is devoted to troubleshooingt system malfirnctions. We develop an automated system that uses Bayesian Belief Networks (BBNs) for effective troubleshooting. BBNs are ideal paradigms to represent the causality an...
