Murphy, Emma, Kuber, Ravi, McAllister, Graham, Strain, Philip and Yu, Wai (2008): An empirical investigation into the difficulties experienced by visually impaired Internet users. In Universal Access in the Information Society, 7 (1) pp. 79-91
In this paper, an empirical based study is described which has been conducted to gain a deeper understanding of the challenges faced by the visually impaired community when accessing the Web. The study, involving 30 blind and partially sighted computer users, has identified navigation strategies, perceptions of page layout and graphics using assistive devices such as screen readers. Analysis of the data has revealed that current assistive technologies impose navigational constraints and provide limited information on web page layout. Conveying additional spatial information could enhance the exploration process for visually impaired Internet users. It could also assist the process of collaboration between blind and sighted users when performing web-based tasks. The findings from the survey have informed the development of a non-visual interface, which uses the benefits of multimodal technologies to present spatial and navigational cues to the user.

Kuber, Ravi, Yu, Wai and McAllister, Graham (2007): Towards developing assistive haptic feedback for visually impaired internet users. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1525-1534. Available online
Haptic technologies are thought to have the potential to help blind individuals overcome the challenges experienced when accessing the Web. This paper proposes a structured participatory-based approach for developing targeted haptic sensations for purposes of web page exploration, and reports preliminary results showing how HTML elements can be represented through the use of force-feedback. Findings are then compared with mappings from previous studies, demonstrating the need for providing tailored haptic sensations for blind Internet users. This research aims to culminate in a framework, encompassing a vocabulary of haptic sensations with accompanying recommendations for designers to reference when developing inclusive web solutions.

Tan, Chui Chui, Yu, Wai and McAllister, Graham (2007): An adaptive & adaptable approach to enhance web graphics accessibility for visually impaired people. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1539-1542. Available online
To date, efforts have been made to enable visually impaired people to gain access to graphics on the Internet. However, these studies only offer a solution for a specific type of graphic by using a fixed set of hardware. To address this, a design approach of an adaptive and adaptable architecture is introduced which adapts to different graphical content, input/output devices (including assistive technologies) and user's profile and preferences. This system brings the opportunity to visually impaired people to gain access to graphics via different modalities by providing an adequate accessibility interface and interaction based on their profiles and needs.

Yu, Wai, McAllister, Graham, Strain, Philip, Kuber, Ravi and Murphy, Emma (2005): Improving web accessibility using content-aware plug-ins. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 1893-1896. Available online
This paper describes a novel approach to improve blind and visually impaired people's access to the Web by using a content-aware Web browser plug-in coupled with audio and haptic tools. The Web plug-in accesses the current mouse position on-screen, and makes the co-ordinates available to the audio and haptic modalities. This allows the user to be informed when they are in the vicinity of an image or hyperlink; previously they would only have been informed when they are physically on the link. Thus, when the user is close to an image or hyperlink, haptics and audio will be used to inform and guide them to the actual spatial position. The Web browser plug-in and the associated audio and haptic feedback tools are described in the paper. Finally, results from a pilot study on the usability of this system are also presented.
