New Technologies for Accessible Tactile Math and Accessible Graphics

Tactile Spatial Math Sighted scientists use two-dimensional math equations, because they provide the most intuitive way to represent the math. Any equation can also be written in a linear form, eg LaTeX code, Fortran, BASIC, and C computer codes. Although often more space-efficient than 2D equations, linear equations become very cumbersome for even moderately complex […]
