Spatial computing combines virtual reality, augmented reality, and Internet of Things technologies to digitally map physical spaces and allow digital objects and sensors to interact seamlessly within them. It uses location-based technologies like GPS, LiDAR, and computer vision to precisely track objects in 3D space. Some benefits of spatial computing include more interactive employee training, lower product development costs, and more accessible real estate tours. However, the high costs of spatial computing devices and potential health issues like eye strain and hearing problems pose drawbacks to its adoption.
