Wheelchair users can find accessing digital content on large multi-touch tables particularly difficult and frustrating due to their limited reach. We present work in progress that is exploring the potential of enhancing touch table accessibility through the use of mid-air gesturing technology. An overview of an experimental prototype is provided along with the key findings from an evaluation conducted with fifteen wheelchair users at a public library and heritage centre.

This work examines how common use scenarios for touch interactive stereoscopic displays might exacerbate visual fatigue. We identify technological constraints of current stereoscopic displays and image separation techniques as the potential underlying cause and generate a set of hypotheses concerning the implications for end users. Furthermore we outline a proposed study to examine these hypotheses. © The Authors.

Map-matching algorithms integrate data from positioning sensors with a digital map in order, first, to identify the road link on which a vehicle is traveling, and second, to determine the vehicle's location on that link. Due to errors in positioning sensors, digital maps, and the map-matching (MM) process, MM algorithms sometimes fail to identify the correct road segment from the candidate segments. This phenomenon is known as mismatching. Identification of the wrong road link may mislead users and degrade the performance of a location-based intelligent transportation system (ITS) and services. The main objective of this article is to improve a topological map-matching (tMM) algorithm by error detection, correction, and performance re-evaluation. Errors in a tMM algorithm were determined using data comprising 62,887 positioning points collected in three different countries (the United Kingdom, the United States, and India). After map-matching, each mismatched case was examined to identify the primary causes of the mismatches. A number of strategies were developed and applied to reduce the risk of mismatching thus enhancing the tMM algorithm. An independent data set of 5,256 positioning points collected in and around Nottingham, UK, was employed to re-evaluate the performance of the enhanced tMM algorithm. The original tMM algorithm correctly identified the vehicle's position 96.5% of the time; after enhancement this increased to 97.8%. This compares very well with the performance of tMM algorithms reported in the literature. The enhanced tMM algorithm developed in this research is simple, fast, efficient, and easy to implement. Since the accuracy offered by the enhanced algorithm is found to be high, the developed algorithm has potential to be implemented in real-time location-based ITS applications.

Information Technology (IT) has played a significant role in enhancing the efficiency of modern day transportation systems. Recent advances in sensors, communication and information systems have enabled transportation systems to be more intelligent. Various location technologies and data integration methods (also known as map-matching algorithms) are used to support the navigation modules of such transport systems. This study provides a survey of location based technologies that encompass an Intelligent Transportation System (ITS) and provides an insight into the Required Navigation Performance (RNP) parameters that are required for decision-making in efficient delivery of transport systems. The reseachers also describe how various location sensors and map-matching algorithms are capable of supporting the navigation modules of ITS. © Medwell Journals, 2011.

Purpose – The purpose of this paper is to provide a review of the experiences in working collaboratively with physically impaired visual artists and other stakeholders (e.g. disability arts organisations, charities, personal assistants, special needs colleges, assistive technologists, etc.) to explore the potential of digital assistive tools to support and transform practice. Design/methodology/approach – The authors strategically identified key organisations as project partners including Disability Arts Shropshire, Arts Council England, the British Council, SCOPE, and National Star College (a large special needs college). This multi-disciplinary team worked together to develop relationships with disabled artists and to collaboratively influence the research focus around investigating the current practice of physically impaired artists and the impact of digital technologies on artistic work. Findings – The collaborations with disabled artists and stakeholders throughout the research process have enriched the project, broadened and deepened research impact, and enabled a firsthand understanding of the issues around using assistive technology for artistic work. Artists and stakeholders have become pro-active collaborators and advocates for the project as opposed to being used only for evaluation purposes. A flexible research approach was crucial in helping to facilitate research studies and enhance impact of the work. Originality/value – This paper is the first to discuss experiences in working with physically impaired visual artists – including the benefits of a collaborative approach and the considerations that must be made when conducting research in this area. The observations are also relevant to researchers working with disabled participants in other fields. © 2016, © Emerald Group Publishing Limited.

Technological developments open new opportunities to meet the increasing expectations of museum visitors. Although these technologies provide many new possibilities, individual challenges and limitations are rife. Museums should aim to unify many such technologies in order to capture visitor attention, engage interaction and facilitate social activities. By incorporating exhibits, objects, devices and people into a network of interconnected systems, new patterns, interaction types and social relations are expected to emerge. The goal of the research described in this paper is to explore the behavioural patterns emerging from visitors' interaction within the museum environment, how these patterns can be utilised in order to create new engaging and social experiences and how unifications of new technologies can contribute to engaging visitor interactions. © 2013 Author.

Ireland is well known for its technology industries, but lately there seems to be some discontent amongst entrepreneurs there that the tax-incentives created by the government to attract overseas tech businesses – particularly US firms – are not nurturing home-grown talent. Recently it emerged that the The Digital Hub, an incubation space for tech development, had 55 desk spaces reserved for US companies but home-grown Irish startups were having difficulty getting space there. A case in point is the recent launch of Moli, a Florida-based company with $30 million in venture backing which, though it initially looked like it was employing a lot of people in Dublin, turned out to have a very small presence there. You might say Ireland is a sweet place for Moli, but not for sweet Molly Malone. So moves are afoot, driven by Irish-born but UK-based Paul Walsh, current chair of the British Interactive Media Association (BIMA). to create an equivalent body in Ireland to represent the digital industry, reports Silicon Republic. The body has a working title of the Irish Digital Industry Association and a recent meeting included Boards.ie founder John Breslin and Joe Drumgoole of ‘digital lifestyle’ storage firm PutPlace. Feedback from Irish commentators about the whole topic have been broadly positive: The idea doesn’t sound like a bad one and so long as it doesn’t turn into an expensive, empty talking shop or too draconian in its dealings with the myriad of other groups in existence, it looks like it will get a fair wind in the community there. But what’s your view?
