Q41.
What is a key characteristic of the theories of situated action and distributed cognition?

a.

They prioritize a priori plans and fixed goals.

b.

They focus on individual cognitive processes.

c.

They emphasize improvisational behavior and reject predefined scripts.

d.

They disregard the role of external environment.

Discuss
Answer: (c).They emphasize improvisational behavior and reject predefined scripts. Explanation:Situated action and distributed cognition theories emphasize improvisational behavior and reject predefined scripts in human behavior. They consider the ongoing interpretation of tasks based on the environment and interactions.
Q42.
How does the theory of situated action differ from the Model Human Processor (MHP) theory?

a.

Situated action emphasizes internal cognitive processes, while MHP focuses on improvisational behavior.

b.

Situated action rejects pre-planned goals and emphasizes improvisational behavior, while MHP assumes a priori plans leading to actions.

c.

Situated action disregards the role of the environment, while MHP emphasizes knowledge in the world.

d.

Situated action prioritizes individual cognition, while MHP focuses on distributed cognition.

Discuss
Answer: (b).Situated action rejects pre-planned goals and emphasizes improvisational behavior, while MHP assumes a priori plans leading to actions. Explanation:Situated action rejects pre-planned goals and emphasizes improvisational behavior, while the Model Human Processor (MHP) theory assumes that actions arise from pre-planned goals.
Q43.
According to distributed cognition, how is knowledge distributed within a system?

a.

Knowledge is centralized in a single individual's cognition.

b.

Knowledge is encoded only in physical objects.

c.

Knowledge is shared and distributed among various elements of the system.

d.

Knowledge is isolated within individual cognitive processes.

Discuss
Answer: (c).Knowledge is shared and distributed among various elements of the system. Explanation:According to distributed cognition, knowledge is shared and distributed among various elements of a system, including both individuals and artifacts.
Q44.
How does the emphasis on knowledge in the world differ between situated action and distributed cognition?

a.

Situated action focuses on the knowledge encoded in individual cognitive processes, while distributed cognition emphasizes external knowledge sources.

b.

Situated action emphasizes knowledge encoded in objects, while distributed cognition disregards knowledge in the environment.

c.

Both theories disregard the concept of knowledge in the world.

d.

Both theories equally prioritize external knowledge sources.

Discuss
Answer: (a).Situated action focuses on the knowledge encoded in individual cognitive processes, while distributed cognition emphasizes external knowledge sources. Explanation:Situated action focuses on the knowledge encoded in individual cognitive processes and how it shapes behavior, while distributed cognition emphasizes the distribution of knowledge among various elements of the system, including objects and individuals.
Q45.
What is the main goal of using ethnography in the context of ubicomp research?

a.

To develop rigid models and frameworks for everyday practices.

b.

To uncover emotional and spiritual aspects of everyday practices.

c.

To create invisible practices that mesh with ubicomp environments.

d.

To gain rich understandings of settings and everyday practices for informing design.

Discuss
Answer: (d).To gain rich understandings of settings and everyday practices for informing design. Explanation:In the context of ubicomp research, the goal of using ethnography is to gain rich understandings of specific settings and the everyday practices within those settings. This understanding helps inform the design of ubicomp environments that seamlessly integrate with people's everyday practices.
Q46.
How does the use of cultural probes differ from ethnography in ubicomp research?

a.

Ethnography focuses on uncovering emotional aspects, while cultural probes uncover routine aspects.

b.

Ethnography focuses on developing new digital devices, while cultural probes inform design by uncovering emotional, unusual, and spiritual aspects.

c.

Ethnography and cultural probes are the same approach with different names.

d.

Ethnography uncovers everyday and routine aspects, while cultural probes focus on emotional, unusual, and spiritual aspects.

Discuss
Answer: (d).Ethnography uncovers everyday and routine aspects, while cultural probes focus on emotional, unusual, and spiritual aspects. Explanation:Ethnography in ubicomp research focuses on uncovering everyday and routine aspects of settings and practices. Cultural probes, on the other hand, seek to uncover emotional, unusual, and even spiritual aspects of settings in order to inspire the development of new digital devices.
Q47.
Why has the development of assessment and evaluation techniques for ubicomp been relatively slow?

a.

Lack of interest from researchers in the ubicomp community.

b.

The rapid evolution of the vision of ubiquitous use of technology.

c.

Difficulty in finding suitable evaluation methods.

d.

Lack of funding for evaluation research in ubicomp.

Discuss
Answer: (b).The rapid evolution of the vision of ubiquitous use of technology. Explanation:The development of assessment and evaluation techniques for ubicomp has been relatively slow due to the gradual evolution of the vision of ubiquitous use of technology. This evolution involves a delicate balance between predicting how novel technologies will serve real human needs and observing authentic use and co-evolution of human activities and technologies.
Q48.
How does the shift away from the desktop in ubicomp impact evaluation methods?

a.

It makes task-oriented approaches more relevant and applicable.

b.

It requires new representations of human activity for assessment.

c.

It renders qualitative evaluation methods ineffective.

d.

It eliminates the need for real-world deployment of ubiquitous environments.

Discuss
Answer: (b).It requires new representations of human activity for assessment. Explanation:The shift away from the desktop in ubicomp requires new representations of human activity for assessment. Traditional task-oriented approaches may not be as relevant or applicable when evaluating ubicomp systems that involve a broader range of activities beyond structured work tasks.
Q49.
Why is it challenging to obtain deeper empirical evaluation results for ubicomp applications?

a.

There is a lack of interest from users in participating in evaluation studies.

b.

The technology used in ubicomp systems is often unreliable.

c.

Controlled studies in traditional usability laboratories are ineffective for ubicomp evaluation.

d.

Ubiquitous devices are too expensive to deploy in real-world settings.

Discuss
Answer: (c).Controlled studies in traditional usability laboratories are ineffective for ubicomp evaluation. Explanation:Controlled studies in traditional usability laboratories are ineffective for obtaining deeper empirical evaluation results for ubicomp applications. Ubiquitous computing involves real-world, continuous use of systems, which cannot be adequately captured in traditional lab settings.
Q50.
How are researchers addressing the challenge of obtaining real-world evaluation results for ubicomp systems?

a.

By conducting surveys and questionnaires with users.

b.

By deploying systems in traditional usability laboratories.

c.

By creating testbeds and living laboratories in authentic settings.

d.

By focusing on developing more robust and reliable prototypes.

Discuss
Answer: (c).By creating testbeds and living laboratories in authentic settings. Explanation:Researchers are addressing the challenge of obtaining real-world evaluation results for ubicomp systems by creating testbeds and living laboratories in authentic settings. These testbeds allow researchers to deploy ubiquitous devices in real-world environments to gather data and insights from actual user interactions.
