Role of Virtual Automation and Augmented Reality

Augmented Reality (AR) is a technology that overlays virtual objects onto the real world, enhancing the observer's perception and understanding. Virtual Reality (VR), on the other hand, allows users to immerse themselves in a computergenerated environment, whether a recreation of the real world or an entirely imagined one. AR and VR serve as gateways to exploring and experiencing the past, present, and future. They provide a foundation for creating personalized, immersive realities—whether designing a video game, taking a virtual tour of the universe, visualizing a dream home, or walking on an alien planet. These technologies enable users to safely experience and learn from even the most challenging and high-risk scenarios. However, only a few truly understand the fundamental principles of VR and AR, along with their open challenges. This survey provides a historical overview of Virtual and Augmented Reality, explores their characteristics and classifications, and discusses the requirements and challenges associated with VR and AR systems.
