Unveiling the Era of Spatial Computing

Abstract: The evolution of User Interfaces marks a significant transition from traditional command-line interfaces to more intuitive graphical and touch-based interfaces, largely driven by the emergence of personal computing devices. The advent of spatial computing and Extended Reality technologies further pushes the boundaries, promising a fusion of physical and digital realms through interactive environments. This paper delves into the progression from All Realities technologies encompassing Augmented Reality, Virtual Reality, and Mediated Reality to spatial computing, highlighting their conceptual differences and applications. We explore enabling technologies such as Artificial Intelligence, the Internet of Things, 5G, cloud and edge computing, and blockchain that underpin the development of spatial computing. We further scrutinize the initial forays into commercial spatial computing devices, with a focus on Apple's Vision Pro, evaluating its technological advancements alongside the challenges it faces. Through this examination, we aim to provide insights into the potential of spatial computing to revolutionize our interaction with digital information and the physical world.
