Augmented reality (AR) is an extension technology of virtual reality (VR). It mainly uses image input devices to capture real-world scenes and locate them, and then augmented reality systems. The instant computing capability overlays virtual image objects or animations onto real scenes and presents them through augmented reality device displays.
Different from virtual reality, Augmented Reality emphasizes the combination of virtual objects and real-world scenes. Through the presentation of this technology, scenes that have not existed can be reproduced, such as reappearing monuments. Therefore, how to accurately present the virtual object correctly in the real scene is to amplify the most core technology in the real world. In general, augmented reality often uses special tags to identify 3D positioning. However, with the rise of mobile devices and computing power, more and more applications are combined with Global Positioning System (GPS). The positioning function creates a combination of virtual and reality and is used in navigation and navigation applications.
In addition, the augmented reality emphasizes that the user can interact with the virtual object in real time to enhance the sensory stimulation, such as visual effects and sound feedback, so that the user can be more integrated into the virtual reality combination environment constructed by the augmented reality.
