Display systems and anthropometric datA MCQs

1. Which of the following is NOT a type of visual display?
a) LED display
b) LCD display
c) Tactile display
d) Olfactory display

Answer: d) Olfactory display
Explanation: Visual displays primarily utilize sight, such as LED and LCD displays, while tactile displays engage the sense of touch. Olfactory displays, involving smell, are not commonly used in traditional display systems.

2. Factorial displays are primarily used for:
a) Presenting numerical data
b) Displaying complex relationships among variables
c) Emitting warning signals
d) Representing auditory information visually

Answer: b) Displaying complex relationships among variables
Explanation: Factorial displays are designed to represent multifaceted relationships among variables or factors, aiding in the comprehension of complex data structures.

3. Which of the following is an example of a visual indicator?
a) Beeping sound
b) Flashing light
c) Vibrating sensation
d) Foul smell

Answer: b) Flashing light
Explanation: Visual indicators convey information through the sense of sight, such as flashing lights to signify alerts or notifications.

4. Auditory displays are primarily suited for conveying information to individuals who:
a) Have impaired vision
b) Have impaired hearing
c) Have impaired smell
d) Have impaired touch sensitivity

Answer: a) Have impaired vision
Explanation: Auditory displays are effective for individuals with impaired vision as they convey information through sound, compensating for the lack of visual input.

5. Graphic displays are particularly useful for:
a) Providing auditory feedback
b) Displaying textual information
c) Presenting data trends visually
d) Emitting tactile signals

Answer: c) Presenting data trends visually
Explanation: Graphic displays present data visually, making them effective for illustrating trends, patterns, and relationships within the data.

6. Which of the following characteristics is essential for tactile displays?
a) Brightness
b) Texture
c) Loudness
d) Contrast

Answer: b) Texture
Explanation: Tactile displays rely on the sense of touch, making texture a crucial characteristic for conveying information effectively.

7. What is the primary purpose of warning signals in display systems?
a) To entertain users
b) To provide aesthetic appeal
c) To alert users of potential hazards
d) To enhance user comfort

Answer: c) To alert users of potential hazards
Explanation: Warning signals in display systems serve the critical function of alerting users to potential dangers or risks, enhancing safety and awareness.

8. Which type of display primarily relies on auditory feedback?
a) LCD display
b) LED display
c) Auditory display
d) Graphic display

Answer: c) Auditory display
Explanation: Auditory displays communicate information primarily through sound, making them distinct from visual displays such as LCD and LED displays.

9. In display systems, what is the significance of selecting appropriate characteristics for auditory displays?
a) To enhance visual appeal
b) To improve tactile feedback
c) To ensure effective communication
d) To optimize olfactory perception

Answer: c) To ensure effective communication
Explanation: Selecting appropriate characteristics for auditory displays is crucial to ensure clear and effective communication of information to users.

10. Which sense is primarily engaged in tactral display systems?
a) Sight
b) Hearing
c) Touch
d) Smell

Answer: c) Touch
Explanation: Tactile display systems primarily engage the sense of touch, providing users with physical feedback or information through tactile sensations.
