Due to a production error, Figures 1, 2 have been included in the article in the wrong order. Figure 1 should be listed as Figure 2, and Figure 2 should be listed as Figure 1. The figures in the correct order appear below.

FIGURE 1

FIGURE 1. State diagram of the guiding state machine, showing how the agent behaves based on the distance between it and the visitor (d_a2v) and the distance between it and the current node (d_a2n). Authors can configure the agent’s behavior using the parameters a—d. The states “going back,” “waiting,” “guiding slowly,” and “guiding fast” are accessedd based on a, b and d_a2v. If the agent detects an obstacle on the path, it calculates new nodes and adds them to the path. When it arrives at a node, it starts to move to the next node. If there are no more next nodes, the state is set to “arrived”.

FIGURE 2

FIGURE 2. Flowchart of the authoring process and its two phases. Authors start with process-specific tasks in phase 1. They use Unity and our authoring tools to adapt their AR nuggets and to deploy an authoring as well as a user application. In phase 2, authors use an AR device to perform location-specific authoring tasks like placing and scaling augmentations or testing the AR experience from a visitor’s point of view. The authoring process is iterative and authors might go back to phase 1 to further adapt their AR nuggets.
