Equdia: diagrames per a la interpretació visual d'equacions en dispositius mòbils

Abstract

Nowadays the way we interact with electronic devices is causing side stop devices like mouse or physical keyboard to be completely touchable. This change encourages new ways of develop software. This raises Equdia, an application with a new way of representing mathematical formulas oriented touch devices. This hierarchical representation is intuitive, based on the primitive logic of triangle as the fundamental unit. The application is designed to directly manipulate primitives to observe the impact of these changes in the other variables. It focuses both teaching calculus, so as to everyday, so as professional activities. Its usability has been tested and it has been well received, especially in the young groups, accustomed to use phones and tablets, because this software requires a learning time for its use.
