FIG 1.

The setup. The left panel is an aerial view of the location of the experiment. The angiography suite (labeled) is in the hospital, which is separate from the proctor's location in the adjacent building (labeled). The right panel shows the operator's environment in the angiography suite (lower panel) with the operator wearing the OST-HMD and the spatial computer. The hotspot connection is demonstrated by the orange link between the OST-HMD and the laptop in the angiography suite and between the laptop and the computer in the proctor's office via the Zoom link. The direct Wi-Fi connection is demonstrated by the blue link between the OST-HMD worn by the operator with direct streaming to the computer in the proctor's office.
