Key Benefits of AR in HMI Interaction

Traditional schematics and two- dimensional diagrams force techniques to mentally map flat drawings to o three-dimensional equipment - a process that is error- prone, especially for novices. AR eliminates that translation step by rendering a 3D model of thee assembly overlaid one thee actuail hardware.
