This paper describes research that investigates the application of Augmented Reality (AR) in 3D animation of simulated construction operations. The objective is an AR-based platform that can be used together with corresponding equipment (HMD, GPS receiver, and a portable computer) to generate a mixed view of the real world and superimposed virtual(More)
Visualization is a powerful method for verifying, validating, and communicating the results of a simulated model. Lack of visual understanding about a simulated model is one of the major reasons inhibiting contractors and engineers from using results obtained from discrete-event simulation to plan and design their construction processes and commit real(More)
This paper describes research that investigated the application of 3D Augmented Reality (AR) for animating traffic simulation models in real time to support the planning and design of road construction projects. Traditional 3D visualization applications use Virtual Reality (VR) environments to visualize traffic simulations. The significant amount of time(More)
This paper presents a reusable, general-purpose, mobile augmented reality (AR) framework developed to address the critical and repetitive challenges specific to visualization in outdoor AR. In all engineering applications of AR developed thus far, basic functionality that supports accurate user registration, maximizes the range of user motion, and enables(More)
This paper describes research that investigated the application of the Global Positioning System (GPS) and 3DOF angular tracking to address the registration problem in visualization of construction graphics in outdoor Augmented Reality (AR) environments. AR is the overlaying of virtual images and computer-generated information over scenes of the real world(More)
3D computer visualization has emerged as an advanced problem-solving tool for engineering education and practice. For example in civil engineering, the integration of 3D/4D CAD models in the construction process helps to minimize the misinterpretation of the spatial, temporal, and logical aspects of construction planning information. Yet despite the(More)
Recent advances in data collection and operations analysis techniques have facilitated the process of designing, analyzing, planning, and controlling of engineering processes. Mathematical tools such as graphical models, scheduling techniques, operations research, and simulation have enabled engineers to create models that represent activities, resources,(More)
Augmented reality (AR) offers significant potential in construction, manufacturing, and other engineering disciplines that employ graphical visualization to plan and design their operations. As a result of introducing real-world objects into the visualization, less virtual models have to be deployed to create a realistic visual output that directly(More)
Current instruction methods of teaching construction engineering and management rely heavily on traditional pedagogical techniques such as in-class instruction and coursework in core subjects. Such methods often fail to prepare students to effectively handle the complexities of actual projects as they provide limited opportunities for hands-on experience.(More)
