Spatial Mapping

Definition

Spatial mapping is the process of capturing and representing the physical layout of an environment in a digital format, which enables devices to understand and interact with that space. This technology is essential for augmented reality (AR) and mixed reality (MR) applications as it allows digital objects to be accurately placed and aligned within the real world, creating a seamless blend of virtual and physical elements. Accurate spatial mapping enhances user experience by ensuring that virtual content reacts appropriately to the physical environment.
