Augmented Reality-based Support System for Teaching Hand-drawn Mechanical Drawing

This research aims to reduce the time, effort and monetary cost needed for developing various educational materials for teaching hand-drawn mechanical drawing by replacing actual educational materials with virtual ones on an augmented reality (AR) -based support system. This system is used for training of sketching and orthographic projection drawing, and has following features. 1) The virtual educational materials constructed by using 3D-CAD are superimposed to a real-time camera image as AR objects. 2) Students can watch the objects from various directions by using a cubic-marker intuitively. 3) The objects are applied realistic textures similar to the actual materials.
