Science and Math exams often contain many figures and charts. The poster deals with special instructions in making tactile graphics, which helps blind students to obtain better understandings of figures and charts.
For blind students, reading tactile graphics are harder than reading braille. It requires time, and skill. Therefore, one must consider the importance of each figure carefully, and make only the necessary figure into tactile graphics. In reading tactile graphics, blind students can only recognises the whole as a series of details. In addition, the size of the area recognised by touch is smaller than that of vision. Therefore, emphasising the important parts and eliminating noise are necessary in order to make tactile graphics, which can provide an entire picture, while containing all the necessary information. The poster discusses above-mentioned topics with rich data from empirical case studies.
