“…To them, the feeling of empty space between the bars with no haptic or audio feedback was disconcerting and perhaps putting a slightly greater demand. This has coincided with the design guidelines for tactile display proposed by Challis and Edwards (2001). Space between the bars can be confusing and cause disorientation to users.…”

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.

“…Traditional approaches use raised paper to convey maps and charts [12,16], or cork boards with pins and rubber bands to teach mathematical functions [41]. Novel interactive systems are trying to improve these techniques [41,42] but often follow a multimodal approach and thus do not fully leverage our perceptual exploration skills.…”

All images are copyright to their respective owners. ABSTRACTPhysical representations of data have existed for thousands of years. Yet it is now that advances in digital fabrication, actuated tangible interfaces, and shape-changing displays are spurring an emerging area of research that we call Data Physicalization. It aims to help people explore, understand, and communicate data using computer-supported physical data representations. We call these representations physicalizations, analogously to visualizations -their purely visual counterpart. In this article, we go beyond the focused research questions addressed so far by delineating the research area, synthesizing its open challenges, and laying out a research agenda.

“…It is also a technique that has been successfully incorporated in prior information displays for people with visual impairments. Challis and Edwards [9] constructed a musical annotation system for a visually impaired person incorporating a commercial tablet touchpad with a custom plastic tactile overlay. The tactile overlay represented constant elements of the interface, such as musical measures, and used audio feedback to present more dynamic and changing information.…”

Touchscreen computing devices such as the iPhone are becoming more common. However this technology is largely inaccessible to people with visual impairments. We present the results of a requirements capture study that illustrates the problems with touchscreen accessibility, and the choices visually impaired people make when choosing assistive technology. We investigate ways of overcoming touchscreen accessibility problems by comparing a raised paper overlay touchscreen based MP3 player, with a touchscreen gesture based player. Twelve blindfolded participants, and one visually impaired person, were able to operate both players, though there were problems with short impact related operations in the gesture player. From our results we provide guidelines for future designers, to help them exploit the potential of touchscreen technology for visually impaired people.

Design principles for tactile interaction

Abstract: A preliminary set of principles for tactile interface design are described. These have been constructed using the findings of a study into the presentation of music notation to blind people.
