Focus on mechanical detailing
AR CAD System
The AR CAD system consists of the following components
Components of AR CAD Prototype
The Process of Video-Based Marker Detection and Overlay of Virtual Objects
Main Processes of Human Spatial Cognition
Indication of the effort required by different mental transformations associated with changes and factors involved in switching viewing perspectives.
Viewpoint Comparison between AR and AutoCAD
To determine whether standard AutoCAD or AR CAD (AutoCAD + AR view) is more effective in the task of conflict detection with respect to the cognition cost associated with scene/perspective changes.
