Introduction: Technological advances have introduced three-dimensional (3-D) printing as an option for creating tactile maps for people with visual impairments (that is, those who are blind or have low vision), diversifying the types of map products that are available. At the same time, it presents a challenge to map makers to implement designs…

Diagram describing texts are integral part of science and engineering subjects including geometry, physics, engineering drawing, etc. In order to understand such text, one, at first, tries to draw or perceive the underlying diagram. For perception of the blind students such diagrams need to be drawn in some non-visual accessible form like tactile…

Sixteen people with blindness or visual impairments used three different types of tactual maps of the New York City subway system presenting information at three levels of specificity. Results indicated that the tactual maps improved participants' attitudes toward the subway and benefited blind as well as low vision participants. (Author/DB)

Two experiments with a total of 92 elementary grade blind students were conducted to determine the effects of training blind students in shape recognition accuracy and speed and accuracy of locating shapes on a tactile map by using a distinctive features analysis strategy and line tracing. (Author/DB)

Two experimental tactile political map designs were evaluated with 72 blind braille reading students (grades 4-12). (Author/CL)

Point and linear symbols that represent certain areas of building interiors are discussed in light of their reliability and discriminability if used on tactual maps. A set of "optimally sized" symbols were evaluated with 21 blind observers. (Author/DB)

Seventy-two blind braille students in grades 4 through 12 were given map reading tasks on tactile pseudomaps which either contained texture (noisy map) or didn't (noise-free map). (DB)

Eighty-eight children (either totally blind or with residual vision) estimated directions between landmarks in a large scale layout of objects. Children experienced the layout either directly by walking around it or indirectly by examining a tactile map. Use of tactile maps considerably facilitated the performance of the blind children.

Two experiments compared single v double lines on tactile mobility maps using 12 blindfolded sighted Ss, 12 congenitally blind Ss, and 12 adventitiously blinded Ss (age range for all three groups, 7 to 72). (Author)

This study evaluated the effects of three instructional methods (direct experience, cartographic representation (tactile map), and verbal description) on the spatial knowledge of 30 adults with blindness. Results indicated that participants' practical spatial knowledge was better when they learned with a tactile map than in either of the other…

Papers on library services and developments in reading materials for the blind, which were presented at the 1984 Expert Meeting of the IFLA Section of Libraries for the Blind include: (1) "Teaching Map Concepts to the Blind" (R. B. Horsfall and B. Cox, Canada); (2) "Optical Character Recognition 'Reading' for Computerized Braille Production"…
