“Until recently, the existing navigation services do not meet the needs in pedestrian situation. The display of present navigation information is often inappropriate. In this paper, we report two experiments to investigate whether using tactile display to present navigation information is sufficient and appropriate in pedestrian situation. The result of those experiments showed that Tactons could be a successful means of communicating navigation information in user interfaces in pedestrian situations.”

In: Proceedings of OZCHI08 - the CHISIG Annual Conference on Human-Computer Interaction 2008. pp. 239-242. Available online
“Social Proximity Applications (SPAs) have prompted a promising opportunity for mobile services that utilize the changes in daily life in the proximity of mobile users. This paper describes our research-in-progress about designing and developing a mobile SPA, which facilitates social interaction among visitors in a night market crowd. This application allows night market visitors to share their experiences in photos with nearby others via their Bluetooth-enabled mobile phones. The design was based on a two-week field observation in an attempt to investigate the motivations and attitudes towards applications of this type. After a three-night extensive trial we found the value of the application -- privacy-sensitive, playful, and enjoyable, yields high consistency with results from field observation. The ultimate goal is to identify potential engaging design extensions to the current prototype.”

“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.”

“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.”

“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.”

“Recent trend in the development of mobile devices, wireless communications, sensor technologies, weblogs, and peer-to-peer communications have prompted a new design opportunity for enhancing social interactions. This paper introduces our preliminary experiences in designing a prototype utilizing the aforementioned technologies to share life experience. Users equipped with camera phones coupled with short-range communication technology, such as RFID, can capture life experience and share it as weblogs to other people. However, in reality, this is easier said than done. The success of weblogs relies on the active participation and willingness of people to contribute. To encourage active participations, a ranking system, AgreeRank, is specifically developed to get them motivated.”

“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.”

“Recent development and proliferation of mobile devices, wireless communication, and sensor technologies have prompted a new vision of social interactions in the world in which we inhabit. For example, the number of mobile phones that are capable of capturing users' spontaneous life experiences not only in pictures but also in audio and video clips is on the increase. In addition, captured experiences can be sent and shared with others over wireless networks such as WiFi, GSM, GPRS, EDGE, or recently commenced third-generation (3G) protocols. Other technology trends such as weblog and peer-to-peer communication provide a ubiquitous platform and a model of motivating users to share life experiences with other people. The hypothesis is that everyone can be an owner of a weblog which records their experience about place, people, and things that interest them. Initial form of peer-to-peer communication, centralized directory service, can help authors of weblogs attain widespread of popularity and increase the level of participation in this type of interaction. The convergence of these technologies provides new design opportunities for computer-mediated communications. The aim of this paper is to share our experiences in designing and implementing a novel physical prototype which incorporates peer-to-peer communication, weblog, RFID, wireless networking, and mobile phone technologies to enhance social quality of shared life experience.”

Yu, Wai and Brewster, Stephen A. (2003): Evaluation of multimodal graphs for blind people. In Universal Access in the Information Society, 2 (2) pp. 105-124
“This paper introduces the development of a multimodal data visualisation system and its evaluations. This system is designed to improve blind and visually impaired peoples access to graphs and tables. Force feedback, synthesized speech and non-speech audio are utilised to present graphical data to blind people. Through the combination of haptic and audio representations, users can explore virtual graphs rendered by a computer. Various types of graphs and tables have been implemented, and a three-stage evaluation has been conducted. The experimental results have proven the usability of the system and the benefits of the multimodal approach. The paper presents the details of the development and experimental findings, as well as the changes of role of haptics in the evaluation.”

“In this paper, we describe a study comparing the strengths of a multimodal Virtual Reality (VR) interface against traditional tactile diagrams in conveying information to visually impaired and blind people. The multimodal VR interface consists of a force feedback device (SensAble PHANTOM), synthesized speech and non-speech audio. Potential advantages of the VR technology are well known however its real usability in comparison with the conventional paper-based medium is seldom investigated. We have addressed this issue in our evaluation. The experimental results show benefits from using the multimodal approach in terms of more accurate information about the graphs obtained by users.”

“Line graphs stand as an established information visualisation and analysis technique taught at various levels of difficulty according to standard Mathematics curricula. It has been argued that blind individuals cannot use line graphs as a visualisation and analytic tool because they currently primarily exist in the visual medium. The research described in this paper aims at making line graphs accessible to blind students through auditory and haptic media. We describe (1) our design space for representing line graphs, (2) the technology we use to develop our prototypes and (3) the insights from our preliminary work.”
