Factors Affecting Line Tracing in Tactile Graphs.
Barth, John L.
Journal of Special Education, v17 n2 p215-26 Sum 1983
Twenty-four braille readers (grades 4-12) performed a line-tracking task on tactile line graphs which differed in the type of raised line used to represent the data curves and natures of the display backgrounds. Grids impaired the trackability of every line tested, while line type and grade level had only marginal effects. (Author/CL)
