Q31.
How does the concept of "everyday computing" differ from traditional HCI design?

a.

Everyday computing focuses on well-defined tasks with clear beginnings and ends.

b.

Everyday computing emphasizes formal activities rather than informal ones.

c.

Everyday computing promotes unstructured activities typical of daily life.

d.

Everyday computing involves complex task management.

Discuss
Answer: (c).Everyday computing promotes unstructured activities typical of daily life. Explanation:The concept of "everyday computing" differs from traditional HCI design by promoting unstructured activities typical of daily life, rather than focusing solely on well-defined tasks.
Q32.
What is the key distinction between activities and tasks?

a.

Activities are composed of multiple tasks, whereas tasks are stand-alone.

b.

Activities require more effort than tasks.

c.

Activities have clear beginnings and ends, while tasks are ongoing.

d.

Activities are formal, while tasks are informal.

Discuss
Answer: (a).Activities are composed of multiple tasks, whereas tasks are stand-alone. Explanation:Activities are often composed of multiple tasks, whereas tasks are individual actions or steps.
Q33.
Why is designing for continuously available interaction challenging?

a.

Users are not interested in continuous interaction.

b.

Activities rarely have a clear beginning or end, requiring greater flexibility.

c.

Interruptions are not expected during activities.

d.

Multiple activities cannot operate concurrently.

Discuss
Answer: (b).Activities rarely have a clear beginning or end, requiring greater flexibility. Explanation:Designing for continuously available interaction is challenging because activities rarely have a clear beginning or end, which requires greater flexibility in the design to accommodate this aspect.
Q34.
How does the concept of "associative models of information" relate to designing for continuous interaction?

a.

It helps design activities with clear beginnings and ends.

b.

It ensures that tasks are well-defined and sequential.

c.

It addresses the need for information to be reused from multiple perspectives.

d.

It simplifies the coordination of multiple concurrent activities.

Discuss
Answer: (c).It addresses the need for information to be reused from multiple perspectives. Explanation:The concept of "associative models of information" is important in designing for continuous interaction because it addresses the need for information to be reused from multiple perspectives, which is a characteristic of activities.
Q35.
What does the term "orchestrating daily routines" refer to in the context of everyday computing?

a.

Designing applications for well-defined tasks.

b.

Automating all tasks in daily life.

c.

Managing information through structured processes.

d.

Supporting informal and unstructured daily activities.

Discuss
Answer: (d).Supporting informal and unstructured daily activities. Explanation:In the context of everyday computing, "orchestrating daily routines" refers to supporting informal and unstructured daily activities that are typical of much of our everyday lives.
Q36.
What is the main shift in focus that occurs in ubiquitous computing (ubicomp) compared to traditional computing?

a.

Ubicomp emphasizes individual machine interaction.

b.

Ubicomp focuses on solitary user experiences.

c.

Ubicomp shifts from desktop-based to environment-based interactions.

d.

Ubicomp promotes single-device interactions.

Discuss
Answer: (c).Ubicomp shifts from desktop-based to environment-based interactions. Explanation:The main shift in focus in ubiquitous computing is from desktop-based interactions to interactions that are integrated with the surrounding environment.
Q37.
How does the concept of "knowledge in the world" differ from "knowledge in the head" in HCI design?

a.

"Knowledge in the world" focuses on internal cognitive processes, while "knowledge in the head" emphasizes external interactions.

b.

"Knowledge in the world" is about physical actions, while "knowledge in the head" is about mental processes.

c.

"Knowledge in the world" refers to external artifacts and the environment, while "knowledge in the head" relates to internal mental processes.

d.

"Knowledge in the world" is based on individual cognition, while "knowledge in the head" involves collaborative cognition.

Discuss
Answer: (c)."Knowledge in the world" refers to external artifacts and the environment, while "knowledge in the head" relates to internal mental processes. Explanation:In HCI design, "knowledge in the world" refers to the use of external artifacts and the environment to support interactions, while "knowledge in the head" relates to internal mental processes.
Q38.
Which theory emphasizes the transformational properties of artifacts and the fluid execution of actions and operations in ubicomp?

a.

Situated action theory

b.

Distributed cognition theory

c.

Activity theory

d.

Model Human Processor theory

Discuss
Answer: (c).Activity theory Explanation:Activity theory emphasizes the transformational properties of artifacts and the fluid execution of actions and operations. This theory is often applied in the design and evaluation of ubicomp systems.
Q39.
How does activity theory differ from the Model Human Processor theory?

a.

Activity theory focuses on internal cognitive processes, while Model Human Processor theory emphasizes external interactions.

b.

Activity theory emphasizes fixed, a priori plans, while Model Human Processor theory considers fluid actions and operations.

c.

Activity theory recognizes the transformational properties of artifacts, while Model Human Processor theory doesn't.

d.

Activity theory relies on situated action, while Model Human Processor theory focuses on distributed cognition.

Discuss
Answer: (c).Activity theory recognizes the transformational properties of artifacts, while Model Human Processor theory doesn't. Explanation:Activity theory recognizes the transformational properties of artifacts, while Model Human Processor theory doesn't. Activity theory is more focused on the relationship between users and their environment, including artifacts.
Q40.
What does "knowledge in the head" refer to in the context of HCI design?

a.

External artifacts and the environment

b.

Internal cognitive processes and mental activities

c.

Transformational properties of artifacts

d.

Fluid execution of actions and operations

Discuss
Answer: (b).Internal cognitive processes and mental activities Explanation:In the context of HCI design, "knowledge in the head" refers to internal cognitive processes and mental activities that individuals engage in during interactions.
