Q151.
What is a benefit of using a head-up display in aircraft?

a.

It provides a larger field of view for the pilot

b.

It eliminates the need for cockpit instruments

c.

It reduces the pilot's workload and improves situational awareness

d.

It displays all information in a digital format

Discuss
Answer: (c).It reduces the pilot's workload and improves situational awareness Explanation:A benefit of using a head-up display in aircraft is that it reduces the pilot's workload and improves situational awareness. By projecting essential information directly in the pilot's line of vision, the head-up display allows them to maintain focus on the outside environment while accessing critical data.
Q152.
How are auditory signals utilized in computer systems?

a.

They convey system output

b.

They provide feedback in interactive systems

c.

They can enhance interactive performance

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Auditory signals are utilized in computer systems to convey system output, provide feedback in interactive systems, and potentially enhance interactive performance. Sounds such as beeps, clicks, and tones are used to varying effect in combination with visual displays.
Q153.
What advantage does auditory feedback offer in interactive systems?

a.

It speeds up user performance

b.

It provides confirmation of successful actions

c.

It improves the overall user experience

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Auditory feedback in interactive systems, such as the click sound when pressing a keyboard key or different tones when pressing telephone keypad keys, can speed up user performance, provide confirmation of successful actions, and contribute to an improved overall user experience.
Q154.
How can the use of sound improve interactions with computer systems?

a.

It can reduce awkwardness and stress in user interactions

b.

It can enhance user performance and enjoyment

c.

It can provide clearer communication and information transfer

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The use of sound in computer systems can reduce awkwardness and stress in user interactions, enhance user performance and enjoyment, and provide clearer communication and information transfer. Sound can play a significant role in creating more effective and pleasant interactions.
Q155.
What are haptic devices?

a.

Devices used in virtual reality environments for tactile feedback

b.

Devices used to enhance the visual display in computer systems

c.

Devices used for olfactory (smell) feedback in computer applications

d.

Devices used to simulate touchscreens in mobile devices

Discuss
Answer: (a).Devices used in virtual reality environments for tactile feedback Explanation:Haptic devices are devices used in virtual reality environments (and sometimes in the real world) to provide tactile feedback. These devices simulate sensations of touch, force, resistance, and texture to enhance the user's physical senses.
Q156.
How are haptic devices used in medical domains?

a.

To enhance the visual representation of surgical procedures

b.

To simulate the feel of instruments moving through different tissue types

c.

To provide auditory feedback during medical training

d.

To enable touch-based interactions in virtual reality simulations

Discuss
Answer: (b).To simulate the feel of instruments moving through different tissue types Explanation:In medical domains, haptic devices are used to simulate the feel of instruments moving through different tissue types. These devices provide force feedback, offering different amounts of resistance based on the virtual operation being performed, allowing medical professionals to practice surgical procedures in a realistic virtual environment.
Q157.
In what other real-world interfaces are haptic devices used?

a.

Electronic braille displays

b.

Automotive controls with force feedback

c.

Virtual reality gaming consoles

d.

Touch-sensitive mobile devices

Discuss
Answer: (b).Automotive controls with force feedback Explanation:Haptic devices are also used in real-world interfaces, such as automotive controls with force feedback. These devices provide physical sensations to users, enhancing their interaction with the controls and providing tactile feedback in response to their actions.
Q158.
What is an example of the power of tactile feedback in the context of driving a car?

a.

The ability to feel small bumps in the road and correct the course of the car

b.

The ability to sense pressure and react to keep limbs in desired positions

c.

The ability to perceive textures when resting the hand on a surface

d.

The ability to detect changes in neighboring points on the skin

Discuss
Answer: (a).The ability to feel small bumps in the road and correct the course of the car Explanation:The power of tactile feedback in the context of driving a car is evident when feeling small bumps in the road. The car is slightly sent off course, but drivers often correct their steering before consciously being aware of the bump.
Q159.
Why is texture more difficult to recreate using haptic devices?

a.

It depends on small changes between neighboring points on the skin

b.

It requires conscious effort and control

c.

It is not a strong cue to memory

d.

It is not an effective design element

Discuss
Answer: (a).It depends on small changes between neighboring points on the skin Explanation:Texture is more difficult to recreate using haptic devices because it depends on small changes between neighboring points on the skin. Our senses typically perceive textures when we move our fingers over a surface, rather than when resting on it.
Q160.
What is the challenge in recreating smells dynamically in response to games or internet sites?

a.

Our noses have a small set of basic smells that can be mixed

b.

Smells trigger memory but cannot be changed rapidly

c.

There is no mass market for smell-generating devices

d.

Different types of receptors respond to different chemicals in the air

Discuss
Answer: (d).Different types of receptors respond to different chemicals in the air Explanation:The challenge in recreating smells dynamically is that our noses have thousands of different types of receptors, each responding to different chemicals in the air. This makes it technically difficult to generate smells in a controlled and dynamic manner.
