Video Prototype: The drone used in our concept creation is
the Parrot AR Drone 2.0, which is controlled using a smartphone
app via a WiFi interface. In the video concept the drone
was operated by one of the researchers. In addition, we used
the After Effects software tools to add the lighting effects,
ambient street sounds, and the drone motor noise. Three final
videos were produced and used in our study to represent the
three conditions (A, B, and C). We demonstrate the concept
as a video in a third-person view to allow the actions of the
actor to be clearly visible in relation to the drone and the surroundings.
An example of several screenshots of the lighting
effects is demonstrated in Figure 1.
