Equipment for the Water condition. The participant was equipped with the DIVR headset (A) encasing a Samsung S8 mobile phone displaying the VR activity. During the activity, the participant with their head underwater breathed through a snorkel (B). In order to keep the participant positively buoyant, a flotation belt (C) was placed around their hips. The flotation belt clipped into an elastic tether (D) attached to a 40-lb anchor placed on the pool floor (F). A pair of orange armbands (E) were attached to the tether mid-water and were used as an orange mark to draw the participant's attention to where they would start the VR activity before entering the water.
