IoT integration in augmented reality refers to the incorporation of Internet of Things (IoT) devices and data into AR applications. IoT devices are connected to the internet and can collect and exchange data. AR can provide a visual layer for users to interact with and visualise data from these devices. For example, AR can display real-time sensor data, control smart devices, or provide contextual information based on IoT inputs. This integration enhances the user experience by offering context-aware and data-rich AR applications. It has applications in areas like smart home control, industrial IoT, and healthcare, where AR provides a user-friendly interface for interacting with the broader network of connected devices and data.
