چکیده
In the first article Anke Brock and Christophe Jouffrais give an overview of their research on making geographic maps accessible to visually impaired users. They developed an accessible interactive map prototype composed of a raised-line overlay, an interactive tabletop, and speech output. Their work is currently being used in some classrooms in France for teaching geography to visually impaired children.

From Open Geographical Data to Tangible Maps: Improving the Accessibility of Maps for Visually Impaired People
Visual maps must be transcribed into (interactive) raised-line maps to be accessible for visually impaired people. However, these tactile maps suffer from several shortcomings: they are long and expensive to produce, they cannot display a large amount of information, and they are not dynamically modifiable. A number of methods have been developed to automate the production of raised-line maps, ...
متن کاملInteractivity Improves Usability of Geographic Maps for Visually Impaired People
Tactile relief maps are used by visually impaired people to acquire mental representation of space, but they retain important limitations (limited amount of information, braille text, etc.). Interactive maps may overcome these limitations. However, usability of these two types of maps had never been compared. It is then unknown whether interactive maps are equivalent or even better solutions th...
متن کاملAudio Tactile Maps (ATM) System for Environmental Exploration by Visually-impaired Individuals
Navigation within open and closed spaces requires analysis of a variety of acoustic, proprioceptive and tactile cues; a task that is well-developed in many visually-impaired individuals but for which sighted individuals rely almost entirely on vision. For the visually-impaired, the creation of a cognitive map of a space can be a long process for which the individual may repeat various paths num...
متن کاملNavigating Maps With Little Or No Sight: An Audio-Tactile Approach
This paper first presents a review of the options available for conveying maps and graphics to visually impaired and blind people. A novel audio-tactile methodology is described, and the results from its pilot study reported. Communication of spatial media, such as map, is problematic without sight. Tactile perception is serial rather than synoptic. By building a working model of the environmen...
متن کاملDesign and User Satisfaction of Interactive Maps for Visually Impaired People
Multimodal interactive maps are a solution for presenting spatial information to visually impaired people. In this paper, we present an interactive multimodal map prototype that is based on a tactile paper map, a multi-touch screen and audio output. We first describe the different steps for designing an interactive map: drawing and printing the tactile paper map, choice of multitouch technology...
