The experimental setup of the invisible body condition, left panel, and the mannequin condition. The participants were fitted with a set of head-mounted displays that showed the real-time 3-D video feed of a pair of downward-facing cams that were mounted on the wall or on the head of a mannequin. The scientist applied touches to the participants’ body and the corresponding body part of the invisible body/mannequin using a paintbrush. The grayed-out body in the left panel illustrates the discrete portion of empty space that was meant to represent the invisible body. Two sample frames of the actual visual stimuli presented in head-mounted displays are shown below, featuring the brushing procedure and knife threat event for the two conditions, respectively.

Heat cloak: a series of concentric rings lets heat propagating from left to right across a metallic sheet flow more readily around a thermally isolated disk than toward its center, leaving no sign of the disk in the temperature distribution on the right side; the colors represent temperatures measured with an infrared camera and are superimposed on a photo of the structure before the rubbery insulating material was added to the holes and gaps; the white lines connect points at the same temperature (R. Schittny / KIT)
