Q141.
What happens when there is a delay in producing images in response to head movement in VR?

a.

The visuals become blurry

b.

The feeling of disorientation increases

c.

The user's brain gets confused

d.

Users experience a loss of presence in the virtual environment

Discuss
Answer: (b).The feeling of disorientation increases Explanation:When there is a delay in producing images in response to head movement in VR, the feeling of disorientation increases. The brain expects the visuals to change accordingly with head movement, and a delay can disrupt the sense of presence and cause discomfort.
Q142.
What is the similarity between VR-induced motion sickness and being at sea?

a.

The feeling of disorientation

b.

The rocking motion

c.

Confusion in the brain

d.

Nausea and sickness

Discuss
Answer: (b).The rocking motion Explanation:The similarity between VR-induced motion sickness and being at sea is the rocking motion. When at sea, the boat's motion and the visual cues of the moving horizon can cause a sense of disorientation and motion sickness, similar to how a lag in VR visuals can lead to discomfort.
Q143.
What is the purpose of simulators and VR caves in virtual reality systems?

a.

To enhance the quality of the visuals

b.

To provide a more immersive experience

c.

To reduce the risk of motion sickness

d.

To project the virtual world onto larger screens

Discuss
Answer: (d).To project the virtual world onto larger screens Explanation:Simulators and VR caves in virtual reality systems are designed to project the virtual world onto larger screens. This approach allows for a more immersive experience as the visuals surround the user and can be seen from various angles.
Q144.
How are large flight simulators designed to display the virtual world?

a.

By using head-mounted displays

b.

By projecting scenes onto virtual windows

c.

By creating a 360-degree virtual environment

d.

By using back projectors and surrounding screens

Discuss
Answer: (b).By projecting scenes onto virtual windows Explanation:Large flight simulators display the virtual world by projecting scenes onto virtual windows. The user is placed inside a mock-up of an aircraft cockpit, and the scenes that would be seen through the windows are projected onto the virtual windows.
Q145.
What is a distinguishing feature of VR caves?

a.

They have large displays positioned all around the user

b.

They are designed for specific simulations, such as motorbike or skiing

c.

They use back projectors to create immersive visuals

d.

They are smaller and more portable than other VR systems

Discuss
Answer: (a).They have large displays positioned all around the user Explanation:A distinguishing feature of VR caves is that they have large displays positioned all around the user. This allows the user to look in all directions and see the virtual world surrounding them.
Q146.
What are some examples of applications that employ computers and require specialized devices?

a.

Interactive TV

b.

In-car navigation systems

c.

Personal entertainment

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Applications such as interactive TV, in-car navigation systems, and personal entertainment employ computers and require specialized devices beyond the traditional mouse, keyboard, and screen.
Q147.
What are some alternative visual outputs used in complex systems?

a.

Analog representations of numerical values

b.

Flashing LEDs

c.

Gauges and dials

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Alternative visual outputs used in complex systems can include analog representations of numerical values, flashing LEDs, gauges, and dials. These outputs provide visual information that is unrelated to the traditional screen.
Q148.
What is the purpose of a head-up display (HUD) in aircraft?

a.

To project information directly in front of the pilot's eyes

b.

To display navigational information on a screen

c.

To monitor aircraft status indicators

d.

To replace traditional cockpit instruments

Discuss
Answer: (a).To project information directly in front of the pilot's eyes Explanation:The purpose of a head-up display (HUD) in aircraft is to project a subset of information directly in front of the pilot's eyes. This allows the pilot to view essential information without diverting their attention from looking forward.
Q149.
Why are less important information presented on dials and gauges in the cockpit?

a.

To reduce clutter on the head-up display

b.

To provide additional visual cues for the pilot

c.

To improve the accuracy of the information

d.

To minimize the need for scanning large banks of information

Discuss
Answer: (a).To reduce clutter on the head-up display Explanation:Less important information is presented on dials and gauges in the cockpit to avoid cluttering the head-up display. By presenting this information on separate displays, the head-up display can focus on crucial data, improving the pilot's ability to quickly access essential information.
Q150.
When are the dials and gauges in the cockpit monitored?

a.

During times of high stress

b.

During times of low stress

c.

Continuously throughout the flight

d.

Only during takeoff and landing

Discuss
Answer: (b).During times of low stress Explanation:Dials and gauges in the cockpit are monitored during times of low stress. These displays present less important information that does not require constant monitoring, allowing the pilot to focus on critical tasks during high-stress periods.
