Ageing bodies and the space they call home

Within the population of âolder adultsâ there is more diversity than in any other user group. Yet, generalised assumptions still exist about their capabilities, needs, and technology use. This paper briefly outlines existing research into designing technology for (older) users and suggests that the built environment can, and should, serve as the canvas for new technologies that support the sociophysical interactions of ageing bodies. Innovations coming from the fields of tangible interaction and interactive architecture have the opportunity to consider the whole environment in which such bodies reside. Rather than devising specific technologies for older users, this paper suggests focusing on the incorporation of flexible, mainstream technologies, into adaptable, intelligent homes, which support the autonomy of older adults. The challenges of such an endeavour are discussed as the grounding for future research into sociophysical technology that supports older user

Vote with your feet : hyperlocal public polling for urban screens

Technological advances have led to an ongoing spread of public displays in urban areas. However, they still mostly show passive content such as commercials and digital signage. Researchers took notice of their potential to spark situated civic discourse in public space and have begun working on interactive public display applications. Attracting people’s attention and providing a low barrier for user participation have been identified as major challenges in their design. This thesis presents Vote With Your Feet, a hyperlocal public polling tool for urban screens allowing users to express their opinions. Similar to vox populi interviews on TV or polls on news websites, the tool is meant to reflect the mindset of the community on topics such as current affairs, cultural identity and local matters. It shows one Yes/No question at a time and enables users to vote by stepping on one of two tangible buttons on the ground. This user interface was introduced to attract people’s attention and to lower participation barriers. Vote With Your Feet was informed by a user-centred design approach that included a focus group, expert interviews and extensive preliminary user studies in the wild. Deployed at a bus stop, Vote With Your Feet was evaluated in a field study over the course of several days. Observations of people and interviews with 30 participants revealed that the novel interaction technology was perceived as inviting and that Vote With Your Feet can spark discussions among co-located people

Enhancing learning and assessment of pre-service teachers on practicum placements using mobile technologies with video capture

Across all educational jurisdictions, each year, large numbers of pre-service teachers are assessed for their suitability for teaching during their teacher education courses, in schools and institutions through practicum placements or workplace learning. Despite their widespread use, practicums can be notoriously variable and unreliable in terms of assessment (Rorrison, 2008) and in promoting professional learning (Grudnoff, 2011). The study reported through the publications explicit or referred to in this exegesis focused on the development of a mobile application (‘app’) to address the problems of assessment and professional growth. It was a specific response to the emerging use of mobile devices that utilise video capture, and their impact on assessing students in the practicum component of their training. It drew on existing knowledge of higher education assessments and teacher training assessments, including formative assessments and feedback, linked to the introduction of mobile devices with video capture capabilities. This study examined how mobile technologies, such as smartphones and tablet devices with multimedia capabilities, could address some of the problems faced by pre-service teacher students, their school-based supervisors and the university academics who manage the practicum assessment. The overarching research question of the study was: To what extent can disciplined and structured use of mobile technologies for practicums impact on pedagogy and assessment of professional experiences of pre-service teachers? The study employed a Participatory Action Learning Action Research (PALAR) methodology to address the extent to which disciplined and structured use of mobile technologies impacted on practicum feedback of professional learning experiences of pre-service teachers. The study entailed six participatory research cycles over a four-year period, each consisting of four main phases: planning, acting and observing, reflecting and replanning. A mixed methods approach was used within the observation phases of each cycle. Because of the cyclical features of action research, the study lent itself to publishing findings throughout the project, rather than a single thesis at conclusion. Thus, reports of the research following one or more cycles were published, and this document therefore, is an exegesis of the major papers that were published over the timeframe of the study. The exegesis seeks to unify the publications and provide common themes emerging from the research project. The findings from the several cycles showed that the introduction of mobile technologies had a major impact on the practices and outcomes of pre-service teachers’ practicum experiences. The inclusion of mobile devices with video capture positively impacted on the reflective practices of pre-service teachers as well as formative assessment and feedback for pre-service teachers by providing the opportunity for more detailed, ongoing analysis of pre-service teachers’ performances while on practicum. Findings from the school-based supervising teachers also confirmed the suitability of the ‘app’ for enhancing the practicum experience and its assessment. Further research is required to demonstrate the impact of the application on enhancing learning through the medium of curriculum standards in the school environment. In addition, there is a need to explore more broadly applied mobile feedback systems in the context of practicum assessments

An investigation into trust and security in the mandatory and imposed use of financial ICTs upon older people

Care needs to be taken to reduce the number of people who are fearful and mistrustful of using ICT where that usage is forced upon them without choice or alternative. The growing incidence of mandatory and imposed online systems can result in confusion, misuse, fear, and rejection by people with only rudimentary ICT skills. A cohort where a high percentage of such people occur is older people, defined in this study as people over the age of 60 Examples of compulsory ICT interactions include some banks limiting bank statement access through online rather than paper-based options. Other examples include the purchase of theatre or sports events tickets through ticketing systems that require an online transaction to take place. Increasingly, people are living beyond the normal retiring age. As the older cohort increases in size and in overall global population percentage, the problem of forced technology usage affects technology acceptance, technology trust, and technology rejection. People care about ICT systems where reduced trusted acceptance of technology reduces the advantages of digital health care, the perceived security of banking and shopping, and the autonomy of ICT-driven lifestyle choices. This study aims to solve one of the puzzles of ICT-driven change, where older people can show trepidation towards using technology. By understanding the drivers that influence the choices older people make in relation to ICT systems, it may be possible to introduce a much higher level of trusted acceptance in ICT systems. Although many people adopt ICTs into their lives, many older people face difficulty in using technology when it is forced upon them. This study aims to understand the connection between how choice (or lack of choice) can lead to the rejection or resistance towards ICT usage. Older people sometimes opt towards practices that place themselves at risk of financial or informational disadvantage. This study used a qualitative approach to understanding the factors that influenced the trusted acceptance, trepidation, and in some cases rejection of ICT usage by interviewing a sample of older people. Participants were asked to consider a wide range of ICT-usage scenarios and to describe their intentions. The study focussed on circumstances where ICT usage fell under either mandatory, imposed, or voluntary conditions in order to compare user behaviour. Settings included a range of technology-reliant states that examined IT security, volition and choice, aging, trusted acceptance, and technology adoption. Participants were interviewed to discover and sort the conditions (whether singly or in combination) under which the expectation of ICT acceptance was in some way altered, diminished, or prevented. This research found that older people made poor decisions when the choice to use a technology was replaced with a mandatory or strongly imposed pathway. Mandatory ICT usage across the broad area of financial transactions brought about widespread fear and distrust of online technology usage. The results revealed that many older people not only find these innovations daunting and confronting, but they also have difficulty placing their trust in ICT systems and applications that have become mandatory. In normative conditions, increased ICT acceptance and ICT usage is expected. When ICTs are mandatory in their usage, acceptance is replaced with compulsory procedure. This does not mean that mandatory things cannot be accepted, but rather that older people will accept the need to use a technology according to their perception of what is necessary for their daily and routine interactions. This study showed that voluntary ICT usages including choices increase informed decision-making, security of online financial interactions, and trusted reliance upon ICTs. Choice in ICT usage carries greater trust than mandatory, obligated, or heavily imposed ICTs. The study revealed that mandatory ICT systems can create perceptions of fear, mistrust and uncertainty. In situations where a mandatory ICT system becomes the normative method of transaction, a strong risk to the trusted acceptance of a technology is not merely the lack of ICT-based choice, but also the inability to gain reassurance or secondary confirmation through either face to face or telephone-based communication. Trust in not just the usage, but the implied secure usage of mandated and imposed ICTs, is problematic for older people. This study revealed the significance of mandated ICT systems that limit choices for people, because older humans more readily validate and associate their trust in new innovations when they can access various different professional, technical, peer-based, social and popular opinions. The research also showed that older people are fearful and less trusting in mandatory and imposed systems because they have less financial resilience, and less opportunity to bounce back from loss and disadvantage brought about by digital and online interactions. Older people were worried and reluctant to accept technology at first glance because they knew that they had spent more time than others in a pre-internet, pre-digital environment, and their seminal life experiences are correspondingly less technology-related. The results showed that many older people preferred human communication and interaction rather than communicating, buying, paying, and trusting in purely digital, ICT-based experiences. This demonstrated a gap in the trust and security of digital systems, and the need to address those ICTs that impose and mandate instruments and procedures for daily life. Specifically this study looked at what could reduce unsafe and insecure banking practices by understanding the role of choice in the trusted usage of ICT systems. This study is significant because it shows that older people make financial and social, decisions under reactionary, insecure, and under-informed conditions as a result of a gap in terms of trust security and choice. On the one hand older people develop trust towards a new innovation based on accumulated human discussion, information and reputation. On the other hand older people hold the perception that online systems offer reduced choices. This study led to the development of a model for trusted technology choice (TTCM). It differs from traditional acceptance and diffusion thinking, by having outputs as either ICT acceptance or ICT rejection. It diverges from diffusion and technology acceptance models (TAM), because technology acceptance is not regarded as a foregone conclusion. Instead, it places a very high value upon choice and volition, trust, security and human interaction. The TTCM model, together with a framework for identifying volition barriers, provides a different set of criteria for understanding the needs of older people and their meaningful interactions with new innovation and ICTs. The practical applications for using such a model directly impact upon financial and social stability for older people. Where choices are either removed or limited due to ICT usage, older citizens are unfairly disadvantaged. A model that accurately predicts the trusted usage of ICT innovations can have a widespread effect on the implementation of large-scale public and private systems where the trusted acceptance (or rejection) of each system has on flow impact on financial, health, and other critical services that include the growing population of older people

Domestic Practices and User Experiences Pre- and Post- Occupancy in a Low-Carbon Development

Examination of how household practices, resource flows and social contexts change after moving into an innovative development in Western Australia, with a focus on the home system of practice. This research demonstrates that while some aspects of domestic practices may change when the context changes, entrenched habits and personal practice history prescribe how practices are performed and the subsequent resources consumed

Information credibility perception on Twitter

Information on Twitter is vast and varied. Readers must make their own judgements to determine the credibility of the great wealth of information presented on Twitter. This research aims to identify the factors that influence readers' judgements of the credibility of information on Twitter, especially news-related information. Both internal (within the Twitter platform) and external factors are studied in this research. User studies are conducted to collect readers' perceptions of the credibility of news-related tweets, Twitter features, and the impact of reader characteristics, such as a reader's demographic attributes, their personality and behaviour. Twitter readers are found to depend solely on surface tweet features in making these judgements such as the author's Twitter ID, pictures, or the number of retweets and likes, rather than the tweet's metadata as recommended in previous studies. In this study, surface features are related to cognitive heuristics. Cognitive heuristics are features that the mind uses as shortcuts for making quick evaluations such as deciding the credibility of tweets. There are three main types of cognitive heuristic features found on Twitter that readers use to determine credibility: endorsement, reputation and confirmation. This study finds that readers do not use only one single feature to make credibility judgements but rather a combination of features. External factors such as a reader's educational background and geolocation also have a significant positive correlation with their perceptions of a tweet's credibility. Readers with tertiary level education, or living in a certain location or environment, such as in a crisis or conflict area, are observed to be more careful in making credibility judgements. Readers who possess conscientiousness and openness to experience personality traits are also seen to be very cautious in their credibility judgements. Another insight provided by this research is the categorisation of readers' behaviours according to credibility perceptions on Twitter. The behavioural categorisations are defined by readers' behavioural reliance on Twitter's surface features when judging the credibility of tweets. The findings can assist social media authors in designing the surface features of their social media content in order to enhance the content's credibility. Furthermore, findings from this research can help in developing effective credibility evaluation systems by considering readers' personal characteristics
