Robot Design Using AR

This research addresses the "lack of physical presence" often experienced by novice designers when using 3D CAD systems, where the absence of tactile interaction and spatial context makes it difficult to perceive the actual scale of modeled objects. To resolve this, the project explores the potential of interactive quantitative structure simulation by integrating 3D CAD objects into real-world environments using Augmented Reality (AR). A specialized AR-based simulation system was developed to evaluate how accurately users can perceive and manipulate the dimensions of virtual objects. Experimental results demonstrated high precision, with a relative error of less than 1.3%. The findings indicate that rich environmental cues significantly enhance scale perception, and LCD-based hand-held interfaces allow for more accurate dimensional adjustments compared to Head-Mounted Displays (HMD). This study suggests that AR can effectively bridge the gap between virtual modeling and physical reality in the product design process.
