Web-based multimodal graphs for visually impaired people

This paper describes the development and evaluation of Web-based multimodal graphs designed for visually impaired and blind people. The information in the graphs is conveyed to visually impaired people through haptic and audio channels. The motivation of this work is to address problems faced by visually impaired people in accessing graphical information on the Internet, particularly the common types of graphs for data visualization. In our work, line graphs, bar charts and pie charts are accessible through a force feedback device, the Logitech WingMan Force Feedback Mouse. Pre-recorded sound files are used to represent graph contents to users. In order to test the usability of the developed Web graphs, an evaluation was conducted with bar charts as the experimental platform. The results showed that the participants could successfully use the haptic and audio features to extract information from the Web graphs

Dietary analysis and nutritional behaviour in people with and without age-related macular disease

Background and Aims: Consumption of antioxidant nutrients can reduce the risk of progression of age-related macular degeneration (AMD) - the leading cause of visual impairment in adults over the age of 50 years in the UK. Lutein and zeaxanthin (L&Z) are of particular interest because they are selectively absorbed by the central retina. The objectives of this study were to analyse the dietary intake of a group of AMD patients, assess their ability to prepare and cook healthy food, and to make comparisons with people not affected by AMD. Methods: 158 participants with AMD were recruited via the UK charity The Macular Society, and fifty participants without AMD were recruited from optometric practice. A telephone interview was conducted by trained workers where participants completed a 24 hour food diary, and answered questions about cooking and shopping capabilities. Results: In the AMD group, the average L&Z intake was low in for both males and females. Those able to cook a hot meal consumed significantly more L&Z than those who were not able. Most participants were not consuming the recommended dietary allowance of fibre, calcium, vitamin D and E, and calorific intake was also lower than recommendations for their age-group. The non-AMD group consumed more kilocalories and more nutrients than the AMD group, but the L&Z intake was similar to those with AMD. The main factor that influenced participant’s food choices was personal preference. Conclusion: For an ‘informed’ population, many AMD participants were under-consuming nutrients considered to be useful for their condition. Participants without AMD were more likely to reach recommended daily allowance values for energy and a range of nutrients. It is therefore essential to design more effective dietary education and dissemination methods for people with, and at risk of, AMD

Museum Audio Description: The Problem of Textual Fidelity

Museums present a myriad of source texts, which are often highly ambiguous. Yet Museum Audio Description (AD) is sited in an AD tradition which advocates objectivity. In screen AD, researchers have examined multiple aspects of the translation decisions facing the describer-translator, considering the ways in which AD is shaped by the demands of the source text, the impact of AD on the recipient’s experience and how these aspects may relate to objectivity. We examine the extent to which these decisions may apply to museum AD or differ in a museum setting. We argue that the notion of the ‘source text’ for museums should be expanded beyond the visual elements of museum’s collections, encompassing the wider museum visiting experience. Drawing upon research from Museum Studies and Psychology, we explore the empirical evidence that characterises the experiences of mainstream sighted visitors and discuss the implications for museum AD. If it is to offer true access to the museum experience, then museum AD must consider not only the assimilation of visual information, but also the social, cognitive and emotional elements of visits. From this perspective, the emphasis is shifted from visual to verbal translation to the creative possibilities of re-creation in museum AD

The Journey Experience of Visually Impaired People on Public Transport in London

The use of public transport is critical for Visually Impaired People (VIP) to be independent and have access to out-of-home activities. Despite government policies promoting accessible transport for everyone, the needs of VIP are not well addressed, and journeys can be very difficult to negotiate. Journey requirements can often differ from those of other categories of people on the disability spectrum. Therefore, the aim of this research is to evaluate the journey experience of VIP using public transport. Semi-structured interviews conducted in London are used. The results show that limited access to information, inconsistencies in infrastructure and poor availability of staff assistance are the major concerns. Concessionary travel, on the other hand, encourages VIP to make more trips and hence has a positive effect on well-being. The findings suggest that more specific policies should be introduced to cater to the special needs of particular disabilities rather than generalising the types of aids available. It is also concluded that the journey experience of VIP is closely related to an individual’s independence and hence inclusion in society

Improving Intellectual Access in Temporary Exhibitions for Sight Loss Visitors Through Co-creation and Co-assessment

The research project conveyed in this article explores how to inclusively design and curate a non-permanent design exhibition in a large regional gallery (the National Centre for Craft and Design, UK), focusing on enhanced intellectual access for blind and partially sighted visitors. Intellectual access is defined in this research as making it easy for visitors to grasp the content of an exhibition, even if the recipient has no previous knowledge of the subject. The context and rationale for the research, and how the author has attempted to collaborate with various stakeholders and tailor the co-creation research to the specific needs of the blind and partially sighted participants are imparted. The resulting multi-sensory non-permanent exhibition is also described and how it was tested

Affect and dialogue in collaborative cross-disciplinary research: Developing interactive public art on Cardiff Bay Barrage

Where Cartesian philosophy distinguishes the perceiving and perceptual mind from the body, phenomenology constitutes the experiential/experiencing body as the subject, giving rise to the affective potential of art. An immersive world of digital connections, smart cities and the Internet of Everything dramatises the centrality of relationship, the intertwining of Self and Other, in the lived environments of human experience. This article addresses the contextual, disciplinary and practical challenges encountered in developing an ambitious interactive public art project embedding SMART technology on the coastal fringes of Cardiff, the capital city of Wales (UK). It examines the processes and problems involved in delivering a stimulating aesthetic experience in and on a complex site, for a complex audience profile. It traces, in particular, the dependence of a multi-disciplinary project team on the theoretical and practical effects of affect in their ongoing effort to produce engaging, provocative, socially inclusive interactive public art, in and through human-centred design techniques
