In the case of anesthesia machine training, students may become familiar with the VAM before ever using the real machine. Thus, since these students are already familiar with the 2D VAM, this Real Machine Context’s spatial reorganization of the VAM could be disorienting. To address this disorientation, a heads-up-display (HUD) was implemented (figure 5.5). The HUD shows the familiar VAM icons that are screen aligned and displayed along the bottom of the lens screen; each icon has a 3D arrow associated with it that always points at the corresponding component in the anesthesia machine. Thus, if the user needs to find a specific VAM component’s new location in the context of the anesthesia machine, the user can follow the arrow above the HUD icon and easily locate the spatially reorganized VAM component. Once the user has located all the reorganized VAM components, the user can optionally press a GUI button to hide the HUD.

Figure 5.6:.The real machine (top) is spatially reorganized to align with the VAM (bottom). The arrows demonstrate how the original machine was spatially reorganized.
