Assessing the effectiveness of multi-touch interfaces for DP operation

Navigating a vessel using dynamic positioning (DP) systems close to offshore installations is a challenge. The operator's only possibility of manipulating the system is through its interface, which can be categorized as the physical appearance of the equipment and the visualization of the system. Are there possibilities of interaction between the operator and the system that can reduce strain and cognitive load during DP operations? Can parts of the system (e.g. displays) be physically brought closer to the user to enhance the feeling of control when operating the system? Can these changes make DP operations more efficient and safe? These questions inspired this research project, which investigates the use of multi-touch and hand gestures known from consumer products to directly manipulate the visualization of a vessel in the 3D scene of a DP system. Usability methodologies and evaluation techniques that are widely used in consumer market research were used to investigate how these interaction techniques, which are new to the maritime domain, could make interaction with the DP system more efficient and transparent both during standard and safety-critical operations. After investigating which gestures felt natural to use by running user tests with a paper prototype, the gestures were implemented into a Rolls-Royce DP system and tested in a static environment. The results showed that the test participants performed significantly faster using direct gesture manipulation compared to using traditional button/menu interaction. To support the results from these tests, further tests were carried out. The purpose is to investigate how gestures are performed in a moving environment, using a motion platform to simulate rough sea conditions. The key results and lessons learned from a collection of four user experiments, together with a discussion of the choice of evaluation techniques will be discussed in this paper

Power-by-the-hour: the role of technology in reshaping business strategy at Rolls-Royce

There is a recognised trend of manufacturing companies offering not only products, but services and even complete solutions to business problems. Research has highlighted economic, market demand and competitiveness factors as responsible for the re-shaping of business strategies that this has involved. This study analyses the extent to which another factor, technology, has been a significant factor in the switch from product oriented to service oriented strategies. A case study of the aero engine manufacturer Rolls-Royce is used to analyse the impact of technology, which is found to have led manufacturers to re-shape their business strategies. The study finds that developments in one technology in particular, namely digital electronics, have been a powerful enabling factor facilitating the implementation of service strategies. This provided original equipment manufacturers (OEMs) like Rolls-Royce with a competitive advantage relative to conventional service providers, by enabling them to acquire new knowledge management capabilities

Programming Language Feature Agglomeration

Feature-creep is a well-known phenomenon in software systems. In this paper, we argue that feature-creep also occurs in the domain of programming languages. Recent languages are more expressive than earlier languages. However recent languages generally extend rather than replace the syntax (sometimes) and semantics (almost always) of earlier languages. We demonstrate this trend of agglomeration in a sequence of languages comprising Pascal, C, Java, and Scala. These are all block-structured Algol-derived languages, with earlier languages providing explicit inspiration for later ones. We present empirical evidence from several language-specific sources, including grammar definitions and canonical manuals. The evidence suggests that there is a trend of increasing complexity in modern languages that have evolved from earlier languages

The Dag-Brucken ASRS Case Study

In 1996 an agreement was made between a well-known beverage manufacturer, Super-Cola Taiwan, (SCT) and a small Australian electrical engineering company, Dag-Brücken ASRS Pty Ltd, (DB), to provide an automated storage and retrieval system (ASRS) facility as part of SCT’s production facilities in Asia. Recognising the potential of their innovative and technically advanced design, DB was awarded a State Premiers Export Award and was a finalist in that year’s National Export Awards. The case tracks the development and subsequent implementation of the SCT ASRS project, setting out to highlight how the lack of appropriate IT development processes contributed to the ultimate failure of the project and the subsequent winding up of DB only one year after being honoured with these prestigious awards. The case provides compelling evidence of the types of project management incompetency that, from the literature, appears to contribute to the high failure rate in IT projects. For confidentiality reasons, the names of the principal parties are changed, but the case covers actual events documented by one of the project team members as part of his postgraduate studies, providing an example of the special mode of evidence collection that Yin (1994) calls ‘participant-observation’

A very modern professional: the case of the IT service support worker

The IT profession has retained a reputation as a ‘privileged area of the labour market’ (Webster, 2005, p.4; Bannerji, 2011). Workers practicing IT skills have been at the forefront of the competitive drive for innovation and efficiency gains promoted by a neoliberal enterprise ideology (Blackler et al, 2003). In the last two decades, as systems thinking (e.g. Ackoff, 1999) and customer-centric practices (e.g. Levitt, 2006) have converged in a globally powerful IT service management (ITSM) ‘best practice’ discourse (Trusson et al, 2013), the IT service support worker has emerged to be a worker-type of considerable socio-economic importance. Aside from keeping organizational information systems operative, when such systems fail these workers are called upon to rapidly restore the systems and thus head-off any negative commercial or political consequences. Yet these workers are acknowledged only as objectified resources within the ITSM ‘best practice’ literature (e.g. Taylor, Iqbal and Nieves, 2007) and largely overlooked as a distinctive contemporary worker-type within academic discourse. This paper, through analysis of salary data and qualitative data collected for a multiple case study research project, considers the extent to which these workers might be conceived of as being ‘professionals’. The project approached the conceptual study of these workers through three lenses. This paper focuses on the project’s consideration of them as rationalised information systems assets within ‘best practice’ ITSM theory. It also draws upon our considerations of them as knowledge workers and service workers. We firstly situate the IT service support worker within a broader model of IT workers comprising four overlapping groupings: managers, developers, technical specialists and IT service support workers. Three types of IT service support worker are identified: first-line workers who routinely escalate work; second-line workers; and ‘expert’ single-line workers. With reference to close associations made with call centre workers (e.g. Murphy, 2011) the status of IT service support workers is explored through analysis of: (i) salary data taken from the ITJOBSWATCH website; and (ii) observational and interview data collected in the field. From this we challenge the veracity of the notion that the whole occupational field of IT might be termed a profession concurrently with the notion that a profession implies work of high status. Secondly, the paper explores two forces that might be associated with the professionalization of IT as an occupation: (i) rationalisation of the field (here promoted by the British Computer Society); and (ii) formalisation of IT theoretical/vocational education. A tension is identified, with those IT service support workers whose work is least disposed to rationalisation and whose complex ‘stocks of knowledge’ (Schutz, 1953) have been acquired through time-spent practice laying claim to greater IT professional status. Thirdly, consideration is given to individuals’ personal career orientations: occupational, organizational and customer-centric (Kinnie and Swart, 2012). We find that whilst organizations expect IT service support workers to be orientated towards serving the interests of the organization and its clients, the most individualistically professional tend towards being occupationally orientated, enthusiastically (re)developing their skills to counter skills obsolescence in an evolving technological arena (Sennett, 2006)

A smartphone-based Teleradiology system

The development of a teleradiology application for remote monitoring and processing of patient image data using 2nd generation mobile devices with enhanced network services, is of extreme interest, especially when the final means of display is a smartphone, a very light and compact handheld device. In the following paper the development of applications, that are responsible for remote monitoring and processing of medical images, is investigated

Shares in the EMCA : the time is ripe for true no par value shares in the EU, and the 2nd directive is not an obstacle

The most interesting proposal in the draft European Model Companies Act ( EMCA) concerning shares and the focus of this Article is the recommendation to introduce true no par value shares, as they have been in use in the US for many years and were introduced in Australia, New Zealand but also Finland more recently. Contrary to what has often been assumed, the 2nd EU Company Law Directive does not preclude no par value shares. There is nothing in the wording of the Directive to suggest otherwise, and the reference in the Directive to shares without a nominal value is a reference to Belgian law, which has allowed true no par value shares in all but name since at least 1913. EU member states could therefore introduce such shares even for public companies. True no par value shares offer a far more flexible framework in case of capital increases or mergers, but since under a no par value system there is no link between par value and shareholder rights, additional disclosure about these rights might be warranted under a no par value system. Traditional par value shares offer no protection to creditors, shareholders or other stakeholders, so that their abolition should not be mourned. The threat of new share issues at an unacceptably high discount is more efficiently countered by disclosure and shareholder decision rights
