Regarding Head Tracked Displays, please mark True or False for the items below: 1. Head Tracked Displays (HTDs) track the location of the user’s head and update the image shown based on the user’s perspective. [1]  2. Fishtank VR is not considered a type of Head Tracked Display. [2]  3. One of the pros of HTDs is that they obscure the real world. [3]  4. A con of HTDs is that they have a larger physical footprint compared to other VR systems. [4]  5. Most HTDs are not stereoscopic. [5] 

The standard type of copper tubing used most frequently in the HVAC industry is:

Heat that travels through space and heats solid objects without heating the space in between would be defined as what type of heat transfer?

Carbon monoxide in significant amounts is formed during fuel gas combustion:

When larger A/C loads require larger contactors that operate on line voltage because of their larger size, what additional component must be used to control these contactors?

Referring to the drawing above, which operating sequence description listed below would be correct assuming the system switch and cooling thermostat are closed?

A storyboard is your roadmap when you create an immersive experience. Like a script, your storyboard visually guides you throughout the production process. Mark True or False regarding the following sentences about storyboarding in VR: 1. In VR, instead of objects being defined relative to the system, we define them relative to the user’s point of view. [1] 2. We control exactly when and what the user sees in immersive VR. We have full camera control. This helps when creating a storyboard. [2] 3. Storyboarding in VR can be done by working with probabilistic areas of user attention based on ergonomic data. [3] 4. A likable hero, an immersive setting, and a compelling script are three elements of a good storyboard. [4]
