*5.1. Beacon Deployment*

Eight beacons were deployed inside the University of Greenwich computer laboratory. We have used a virtual grid to map the experimental area and illustrate the geographical positions of the beacons, as depicted in Figure 5.


**Figure 5.** Beacon deployment.

Each grid block represents a 1 m × 1 m area. Grey blocks represent an area that a participant cannot reach (in terms of location) due to an obstacle, whereas the white blocks represent accessible area to the participants. Additionally, the floor plan shows the four sectors within the laboratory. Sectors 2 to 4 are computer bays, and Sector 1 is the technical support staff laboratory area. Throughout the experiments, all of the beacons were configured with an advertising data packet frequency of 7 Hz. This deployment density, as our previous work [41] has shown, provides sufficient performance with respect to location accuracy.
