“…Multimodal technologies can also assist in the mental mapping process, allowing the user to develop greater awareness of objects contained within the environment [17]. While previous studies have aimed to improve access to the web through the use of non-visual browsing techniques [7,10,27,37], the approach proposed here aims to enhance current methods of browsing through the use of multimodal technologies to convey spatial information to the user. Ongoing research aims to bridge the gap between assistive screen reading technologies and mainstream visual Internet browsers by providing an alternative approach to web exploration for visually impaired users.…”

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.

“…The approach Websound [40] transformed structural components of web pages into spatial auditory representations that could be explored by an audio-haptic interface and combined it with text-to-speech output for textual components. A subsequent multimodal approach introduced the sonification of web pages for VIP [41], including text and images. Another approach for audiohaptic retrieval of web information was presented by Yu et al [57].…”

3D models are an important means for understanding spatial contexts. Today these models can be materialized by 3D printing, which is increasingly used at schools for people with visual impairments. In contrast to sighted people, people with visual impairments have so far, however, neither been able to search nor to print 3D models without assistance. This article describes our work to develop an aid for people with visual impairments that would facilitate autonomous searching for and printing of 3D models. In our initial study, we determined the requirements to accomplish this task by means of a questionnaire and developed a first approach that allowed personal computer-based 3D printing. An extended approach allowed searching and printing using common smartphones. In our architecture, technical details of 3D printers are abstracted by a separate component that can be accessed via Wi-Fi independently of the actual 3D printer used. It comprises a search of the models in an annotated database and 3D model retrieval from the internet. The whole process can be controlled by voice interaction. The feasibility of autonomous 3D printing for people with visual impairments is shown with a first user study. Our second user study examines the usability of the user interface when searching for 3D models on the internet and preparing them for the materialization. The participants were able to define important printing settings, whereas other printing parameters could be determined algorithmically.

“…It is hypothesised that by additionally providing an indicator of the complexity of a cell, it would be possible for an overview of the page to be conveyed to the user. This would relate to the macro and micro analysis stages described by [10]. The user could explore the page while a general description overview of each cell was conveyed ("macro viewpoint").…”
