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…

A review of the literature from 1965 to 2008 on tactile maps and models in orientation and mobility yielded four pre-experimental and three experimental articles. The articles were analyzed via best-evidence synthesis--a combined narrative and statistical approach--allowing for recommendations for the most effective use of tactile maps and models.…

Tactile maps are an important means for the education and mobility of people who are visually impaired (that is, are blind or have low vision). Because of the importance of tactile maps, it is essential that they are accessible to people who are visually impaired and correctly interpreted. There has been considerable research on the design of…

More than 60 different tactual maps were created on capsule paper to examine the effectiveness of this process. The medium's composition, steps necessary for map compilation and processing, equipment costs and operations, appropriate symbolization, and advantages and disadvantages of the process are discussed.

Tactile maps for visually impaired persons can be made by drawing lines with an aqueous adhesive solution, dusting with thermoengraving powder, and exposing the card to a source of intense heat (such as a heat gun or microwave oven). A raised line map results. (CL)

The University of Texas at Austin has developed a modular tactual map of the campus and outlying areas to aid visually impaired students. Construction information is summarized. (CL)

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)

Reported are the findings of a research project conducted to design easily reproducible, large-scale maps for use by the blind to improve their mobility and orientation. The emphasis was on maps varying in scale from general orientation maps of metropolitan areas to mobility maps of neighborhoods or individual buildings. The design, construction,…

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.
