Virtual Reality (VR) and Augmented Reality (AR) technologies are considered to be very effective and important innovations. Their applications have already started to make noteworthy gains around the world, and it is expected that their use will increase moving forward. AR and VR technologies have found applications in a wide variety of industries including engineering; healthcare; education; military; sports; entertainment; and cultural heritage. In the construction industry to date, they have effectively been used in scheduling construction projects, for monitoring project progress, in training workers, time and cost management, and in the management of quality and defects. Hardware abstraction, locally distributed applications, distributed environments, rapid prototyping and run time flexibility are success factors which need attention for the design environment. Although there are similarities between the two technologies, there are certain differences that differentiate the two, and provide certain advantages depending on the purpose.
