Augmented Reality for Materials Education
Project Overview
This project focuses on developing an innovative Augmented Reality (AR) application designed to enhance materials science education by providing interactive 3D visualizations of crystal structures and material properties.
Motivation
Traditional materials science education often relies on 2D diagrams and static models to represent complex 3D crystal structures. This limitation makes it challenging for students to fully comprehend the spatial relationships and properties of materials. Our AR application addresses this gap by providing immersive, interactive learning experiences.
