Q181.
What are some physiological changes that can be measured to determine a user's emotional response to an interface?

a.

Keyboard typing speed and accuracy.

b.

Changes in eye movement patterns.

c.

Heart rate, skin secretions, and breathing.

d.

Volume of spoken commands.

Discuss
Answer: (c).Heart rate, skin secretions, and breathing. Explanation:Physiological changes such as heart rate, skin secretions (galvanic skin response), and breathing can provide insights into a user's emotional response to an interface.
Q182.
What is the primary purpose of measuring physiological responses in usability evaluation?

a.

To predict user behavior accurately.

b.

To replace traditional user feedback methods.

c.

To determine the user's physical fitness level.

d.

To understand the user's emotional state during interactions.

Discuss
Answer: (d).To understand the user's emotional state during interactions. Explanation:Measuring physiological responses helps understand the user's emotional state during interactions with an interface, which can provide insights into usability and emotional experiences.
Q183.
Which physiological measurement is associated with indicating levels of arousal and mental effort?

a.

Blood pressure and volume.

b.

Electromyogram (EMG).

c.

Galvanic skin response (GSR).

d.

Electroencephalogram (EEG).

Discuss
Answer: (c).Galvanic skin response (GSR). Explanation:Galvanic skin response (GSR), indicated by changes in skin resistance, is thought to reflect levels of arousal and mental effort.
Q184.
How might physiological measurements help determine user reactions to specific interaction events?

a.

By providing exact emotional labels for each event.

b.

By directly measuring cognitive load during interactions.

c.

By showing correlations between physiological changes and events.

d.

By eliminating the need for user feedback.

Discuss
Answer: (c).By showing correlations between physiological changes and events. Explanation:Physiological measurements can reveal correlations between changes in physiological responses and specific interaction events, potentially helping to identify events that cause stress, frustration, or relaxation.
Q185.
What is a challenge in applying physiological measurements to interaction events?

a.

Clear mapping of physiological changes to specific emotions.

b.

Difficulty in capturing precise keyboard typing speed.

c.

Limited range of events suitable for physiological measurements.

d.

Inability to measure heart rate accurately.

Discuss
Answer: (a).Clear mapping of physiological changes to specific emotions. Explanation:One challenge is the uncertainty in mapping specific physiological changes to particular emotional states or interaction events, making interpretation and analysis complex.
Q186.
What is the key distinction between evaluating a design and evaluating an implementation?

a.

Evaluation of a design focuses on usability testing, while evaluation of an implementation involves expert analysis.

b.

Evaluation of a design is carried out by designers, while evaluation of an implementation involves end users.

c.

Evaluation of a design precedes the creation of a physical artifact, while evaluation of an implementation involves testing a concrete product.

d.

Evaluation of a design is more costly and resource-intensive than evaluation of an implementation.

Discuss
Answer: (c).Evaluation of a design precedes the creation of a physical artifact, while evaluation of an implementation involves testing a concrete product. Explanation:Evaluation of a design occurs before a physical artifact is created, while evaluation of an implementation involves testing a tangible product.
Q187.
What is the advantage of early evaluation during the design process?

a.

It requires minimal resources and effort.

b.

It provides comprehensive insights into system performance.

c.

It allows for easy implementation of changes and problem resolution.

d.

It eliminates the need for expert analysis.

Discuss
Answer: (c).It allows for easy implementation of changes and problem resolution. Explanation:Early evaluation allows for easy implementation of changes and problem resolution before more commitment is made to a particular design.
Q188.
Which evaluation technique is primarily focused on expert analysis and is suitable for early design stages?

a.

Participatory design.

b.

Cognitive walkthrough.

c.

Usability testing.

d.

Post-task walkthrough.

Discuss
Answer: (b).Cognitive walkthrough. Explanation:Cognitive walkthrough is an expert-based technique that is suitable for early design stages and involves analyzing the design's usability.
Q189.
When is evaluation of an implementation most beneficial?

a.

During the early design stages.

b.

When changes to the design are needed.

c.

After significant commitment to a particular design.

d.

When expert analysis is sufficient.

Discuss
Answer: (c).After significant commitment to a particular design. Explanation:Evaluation of an implementation is most beneficial after significant commitment to a particular design since it allows for testing the working system and identifying issues that arise in real-world usage.
Q190.
What is a drawback of late evaluations in the design process?

a.

They are less resource-intensive.

b.

They require minimal user involvement.

c.

Changes can be easily implemented at this stage.

d.

Changes are difficult to implement at this stage.

Discuss
Answer: (d).Changes are difficult to implement at this stage. Explanation:Late evaluations are less profitable and productive since changes become increasingly difficult to implement due to the commitment made to the design.
