A Virtual Reality Application to Make Mathematical Functions Accessible

Abstract

This paper focusses on creating accessible alternatives for the graphical representation of mathematical functions, with particular attention to students with visual impairments and children with Attention Deficit/Hyperactivity Disorder (ADHD). We design a virtual reality (VR) application which can stimulate different senses by immersing students in a virtual reality environment where they can explore the graphical representation of a function and hear how it is played. The purpose of the application is to improve immersion and inclusion in mathematics. The results of the tests show that this type of tool is useful both for learning through play and for students with different learning needs. The use of audio is an effective way to make graphs accessible, but the problem is that there are no universal design principles that apply to various graphs that encode different data types. Additionally, users with ADHD could appreciate the flexibility, speed, cost effectiveness and greater measure of independence provided by the system; however, more research is needed to justify this statement.
