Abstract
Persons with visual impairments can access digital information through screen reading software. Still, accessing mathematical equations is challenging due to their non-linearity. We propose to improve the accessibility of equations by associating a cognitive complexity metric with each equation and then to use this metric to modify their audio rendering. For example, this will allow audio rendering of complex equations by substituting chunks with variables. This will potentially reduce the cognitive load in comprehending equations by persons with visual impairments. Further, this metric needs to be personalized on the basis of various user characteristics.
