Automotive interactive technologies represent an exemplar challenge for user experience (UX) designers, as the concerns for aesthetics, functionality and usability add up to the compelling issues of safety and cognitive demand. This extended abstract presents a methodology for the user-centred creation and evaluation of novel in-car applications, involving real users in realistic use settings. As a case study, we present the methodologies of an ideation workshop in a simulated environment and the evaluation of six design idea prototypes for in-vehicle head up display (HUD) applications using a semi-naturalistic drive. Both methods rely on video recordings of real traffic situations that the users are familiar with and/or experienced themselves. The extended abstract presents experiences and results from the evaluation and reflection on our methods.

This study will be of interest to anyone concerned with a critical appraisal of mental health service users’ and carers’ participation in research collaboration and with the potential of the postcolonial paradigm of cultural safety to contribute to the service user research (SUR) movement. The history and nature of the mental health field and its relationship to colonial processes provokes a consideration of whether cultural safety could focus attention on diversity, power imbalance, cultural dominance and structural inequality, identified as barriers and tensions in SUR. We consider these issues in the context of state-driven approaches towards SUR in planning and evaluation and the concurrent rise of the SUR movement in the UK and Australia, societies with an intimate involvement in processes of colonisation. We consider the principles and motivations underlying cultural safety and SUR in the context of the policy agenda informing SUR. We conclude that while both cultural safety and SUR are underpinned by social constructionism constituting similarities in principles and intent, cultural safety has additional dimensions. Hence, we call on researchers to use the explicitly political and self-reflective process of cultural safety to think about and address issues of diversity, power and social justice in research collaboration.

In an industry worth more than €500 billion annually, producing more than 80 million vehicles worldwide each year and consisting of over 50 major manufacturers worldwide, the automotive industry represents a lucrative but highly competitive manufacturing industry (Deloitte, 2009a; European Automobile Manufacturers Association, 2012). With sales falling in Europe in 2013 for the sixth consecutive year (Boston and Curtin, 2014), automotive manufacturers are increasingly turning to new strategies to retain their share of sales in a contracting market. Some strategies have focused on the industry approach to manufacturing, namely, a technically focused push for a build-toorder process rather than the current build-to-stock approach in order to reduce overall value-chain costs and to increase efficiency (Parry and Roehrich, 2013, p. 13). However, others stress a more customer-orientated approach, striving to develop products that meet customer requirements (Oliver Wyman Group, 2007).

This article conceptualises ‘participatory reluctance’ as a particular orientation to social media that problematises binarised notions of connection and disconnection in social networking sites. It qualitatively examines how the concept has functioned within gay men’s social networking service, Gaydar, among 18- to 28-year-old users of the site in Brisbane, Australia. Participatory reluctance is shown to be a central aspect of the culture of this space, fostered among the studied demographic by the convergence of the growing global push for marriage equality and increasing normalisation of the kinds of gay male identities commonly adopted among this group, with three key factors rooted primarily in Gaydar’s design: (1) young users’ perceptions of the site as a space for procuring casual sex; (2) their perceptions of the imagined user as embodying existing stereotypes of gay masculinity, and; (3) a lack of genuine alternatives in terms of niche digital spaces for gay men’s social networking.

The first User-Focused Service Engineering, Consumption and Aggregation workshop (USECA) in 2011 was held in conjunction with the WISE 2011 conference in Sydney, Australia. Web services and related technology are a widely accepted standard architectural paradigm for application development. The idea of reusing existing software components to build new applications has been well documented and supported for the world of enterprise computing and professional developers. However, this powerful idea has not been transferred to end-users who have limited or no computing knowledge. The current methodologies, models, languages and tools developed for Web service composition are suited to IT professionals and people with years of training in computing technologies. It is still hard to imagine any of these technologies being used by business professionals, as opposed to computing professionals. © 2013 Springer-Verlag.

Section 180 of the Property Law Act 1974 (Qld) makes provision for an applicant to seek a statutory right of user over a neighbour’s property where such right of use is reasonably necessary in the interests of effective use in any reasonable manner of the dominant land. A key issue in an application under s 180 is compensation. Unfortunately, while s 180 expressly contemplates that an order for compensation will include provision for payment of compensation to the owner of servient land there are certain issues that are less clear. One of these is the basis for determination of the amount of compensation. In this regard, s 180(4)(a) provides that, in making an order for a statutory right of user, the court: (a) shall, except in special circumstances, include provision for payment by the applicant to such person or persons as may be specified in the order of such amount by way of compensation or consideration as in the circumstances appears to the court to be just The operation of this statutory provision was considered by de Jersey CJ (as he then was) in Peulen v Agius [2015] QSC 137.

Analysing the engagement of students in university-based Facebook groups can shed light on the nature of their learning experience and highlight leverage points to build on student success. While post-semester surveys and demographic participation data can highlight who was involved and how they subsequently felt about the experience, these techniques do not necessarily reflect real-time engagement. One way to gain insight into in-situ student experiences is by categorising the original posts and comments into predetermined frameworks of learning. This paper offers a systematic method of coding Facebook contributions within various engagement categories: motivation, discourse, cognition and emotive responses.

Historically, drug use has been understood as a problem of epidemiology, psychiatry, physiology, and criminality requiring legal and medical governance. Consequently drug research tends to be underpinned by an imperative to better govern, and typically proposes policy interventions to prevent or solve drug problems. We argue that categories of ‘addictive’ and ‘recreational’ drug use are discursive forms of governance that are historically, politically and socially contingent. These constructions of the drug problem shape what drug users believe about themselves and how they enact these beliefs in their drug use practices. Based on qualitative interviews with young illicit drug users in Brisbane, Australia, this paper uses Michel Foucault’s concept of governmentality to provide insights into how the governance of illicit drugs intersects with self-governance to create a drug user self. We propose a reconceptualisation of illicit drug use that takes into account the contingencies and subjective factors that shape the drug experience. This allows for an understanding of the relationships between discourses, policies, and practices in constructions of illicit drug users.

This paper investigates the effects of experience on the intuitiveness of physical and visual interactions performed by airport security screeners. Using portable eye tracking glasses, 40 security screeners were observed in the field as they performed search, examination and interface interactions during airport security x-ray screening. Data from semi structured interviews was used to further explore the nature of visual and physical interactions. Results show there are positive relationships between experience and the intuitiveness of visual and physical interactions performed by security screeners. As experience is gained, security screeners are found to perform search, examination and interface interactions more intuitively. In addition to experience, results suggest that intuitiveness is affected by the nature and modality of activities performed. This inference was made based on the dominant processing styles associated with search and examination activities. The paper concludes by discussing the implications that this research has for the design of visual and physical interfaces. We recommend designing interfaces that build on users’ already established intuitive processes, and that reduce the cognitive load incurred during transitions between visual and physical interactions.

This paper focuses on the fundamental right to be heard, that is, the right to have one’s voice heard and listened to – to impose reception (Bourdieu, 1977). It focuses on the ways that non-mainstream English is heard and received in Australia, where despite public policy initiatives around equal opportunity, language continues to socially disadvantage people (Burridge & Mulder, 1998). English is the language of the mainstream and most people are monolingually English (Ozolins, 1993). English has no official status yet it remains dominant and its centrality is rarely challenged (Smolicz, 1995). This paper takes the position that the lack of language engagement in mainstream Australia leads to linguistic desensitisation. Writing in the US context where English is also the unofficial norm, Lippi-Green (1997) maintains that discrimination based on speech features or accent is commonly accepted and widely perceived as appropriate. In Australia, non-standard forms of English are often disparaged or devalued because they do not conform to the ‘standard’ (Burridge & Mulder, 1998). This paper argues that talk cannot be taken for granted: ‘spoken voices’ are critical tools for representing the self and negotiating and manifesting legitimacy within social groups (Miller, 2003). In multicultural, multilingual countries like Australia, the impact of the spoken voice, its message and how it is heard are critical tools for people seeking settlement, inclusion and access to facilities and services. Too often these rights are denied because of the way a person sounds. This paper reports a study conducted with a group that has been particularly vulnerable to ongoing ‘panics’ about language – international students. International education is the third largest revenue source for Australia (AEI, 2010) but has been beset by concerns from academics (Auditor-General, 2002) and the media about student language levels and falling work standards (e.g. Livingstone, 2004). Much of the focus has been high-stakes writing but with the ascendancy of project work in university assessment and the increasing emphasis on oracy, there is a call to recognise the salience of talk, especially among students using English as a second language (ESL) (Kettle & May, 2012). The study investigated the experiences of six international students in a Master of Education course at a large metropolitan university. It utilised data from student interviews, classroom observations, course materials, university policy documents and media reports to examine the ways that speaking and being heard impacted on the students’ learning and legitimacy in the course. The analysis drew on Fairclough’s (2003) model of the dialectical-relational Critical Discourse Analysis (CDA) to analyse the linguistic, discursive and social relations between the data texts and their conditions of production and interpretation, including the wider socio-political discourses on English, language difference, and second language use. The interests of the study were if and how discourses of marginalisation and discrimination manifested and if and how students recognised and responded to them pragmatically. Also how they juxtaposed with and/or contradicted the official rhetoric about diversity and inclusion. The underpinning rationale was that international students’ experiences can provide insights into the hidden politics and practices of being heard and afforded speaking rights as a second language speaker in Australia.

This research project investigated a bioreactor system capable of high density cell growth intended for use in regenerative medicine and protein production. The bioreactor was based on a drip-perfusion concept and constructed with minimal costs, readily available components, and straightforward processes for usage. This study involved the design, construction, and testing of the bioreactor where the results showed promising three dimensional cell growth within a polymer structure. The accessibility of this equipment and the capability of high density, three dimensional cell growth would be suitable for future research in pharmaceutical drug manufacturing, and human organ and tissue regeneration.

Natural User Interfaces (NUI) offer rich ways for interacting with the digital world that make innovative use of existing human capabilities. They include and often combine different input modalities such as voice, gesture, eye gaze, body interactions, touch and touchless interactions. However much of the focus of NUI research and development has been on enhancing the experience of individuals interacting with technology. Effective NUIs must also acknowledge our innately social characteristics, and support how we communicate with each other, play together, learn together and collaboratively work together. This workshop concerns the social aspects of NUI. The workshop seeks to better understand the social uses and applications of these new NUI technologies -- how we design these technologies for new social practices and how we understand the use of these technologies in key social contexts.

Recommender systems assist users in finding what they want. The challenging issue is how to efficiently acquire user preferences or user information needs for building personalized recommender systems. This research explores the acquisition of user preferences using data taxonomy information to enhance personalized recommendations for alleviating cold-start problem. A concept hierarchy model is proposed, which provides a two-dimensional hierarchy for acquiring user preferences. The language model is also extended for the proposed hierarchy in order to generate an effective recommender algorithm. Both Amazon.com book and music datasets are used to evaluate the proposed approach, and the experimental results show that the proposed approach is promising.

E-government provides a platform for governments to implement web enabled services that facilitate communication between citizens and the government. However, technology driven design approach and limited understanding of citizens' requirements, have led to a number of critical usability problems on the government websites. Hitherto, there has been no systematic attempt to analyse the way in which theory of User Centred Design (UCD) can contribute to address the usability issues of government websites. This research seeks to fill this gap by synthesising perspectives drawn from the study of User Centred Design and examining them based on the empirical data derived from case study of the Scottish Executive website. The research employs a qualitative approach in the collection and analysis of data. The triangulated analysis of the findings reveals that e-government web designers take commercial development approach and focus only on technical implementations which lead to websites that do not meet citizens' expectations. The research identifies that e-government practitioners can overcome web usability issues by transferring the theory of UCD to practice.
