Question 1

The broad goals of usability are to promote acceptance and use of systems through improved interactive systems, software, developing new kinds of applications to support specific work, and promoting job optimization with the use of information systems. A user interface can effectively disappear if which of the following is correct?

Accepted Answer

When a system is designed well, the user interface becomes intuitive and easy to use, resulting in a user experience where the interface essentially disappears, and the focus shifts to the task at hand. Therefore, Option A is the correct choice. The other options may contribute to usability, but they do not necessarily guarantee the interface disappears.

Question 2

Which of the following entities does not support a role for informaticians in the future?

Accepted Answer

Informaticians play a crucial role in various aspects of healthcare and technology, including usability, training, and life cycle discussions. The statement that informaticians require a graduate education does not directly support a role for them in the future; it's more about a current educational requirement rather than future opportunities or roles.

Question 3

Which of the following frameworks is based on work-centered research and distributed cognition?

Accepted Answer

The UFuRT framework is based on work-centered research and distributed cognition, focusing on understanding user interactions with systems in the context of their tasks and environment.

Question 4

Usability experts cite three main goals of HCI and usability. Which of the following is not a usability goal?

Accepted Answer

The three main goals of HCI and usability are effectiveness, efficiency, and user satisfaction. Replication is not a widely recognized goal of usability.

Question 5

Ethnographic studies have been incorporated within health care settings by informaticians to glean data at the point of care. Which of the following statements about ethnography is true?

Accepted Answer

Ethnography is a qualitative method from anthropology and sociology that involves fieldwork and analysis of people in cultural, social settings. Ethnographers describe the person of interest's point of view focusing on experience and interactions in social settings rather than just the actions themselves. Ethnography is still a valid method of inquiry in many fields, including healthcare informatics. The use of ethnography has been shown to be effective in understanding the context of healthcare delivery and improving patient outcomes.

Question 6

Usability studies can be used to support IT in a number of ways. Which of the following are reasons to complete these studies in a health care setting?

Accepted Answer

Usability studies can assess the adequacy of a design or redesign early on and help determine or clarify user requirements in a health care setting, which can ultimately lead to better overall system adoption and usability. Creating an interest in learning the new system, determining the actual price of the system, and supporting infrastructure are not primary reasons for conducting usability studies in this context.

Question 7

Usability tests are systematic and structured examinations of the effectiveness, efficiency or satisfaction of any component or interactions in the human-computer interaction framework(s). Which of the following is an example of a usability test?

Accepted Answer

The description of satisfaction with a new computerized provider order entry (CPOE) application indicates a usability test is being conducted on the effectiveness of the interaction between the user and the computer system. Options A, B, and C do not mention any specific component or interaction being evaluated in the human-computer interaction framework, and therefore are not examples of usability tests.

Question 8

Which of the following types of usability studies consists of a detailed review of a sequence of real or proposed actions to complete a task in a system?

Accepted Answer

A cognitive walkthrough involves a step-by-step analysis of a user's actions to complete a task, making it the correct answer. Simplified usability tests using early prototypes and exploratory tests are not as focused on specific sequences of actions, and heuristic evaluations or heuristic inspection methods do not involve hands-on interaction with the system.

Question 9

Question 10

The scientific study of the interaction between people, machines, and their work environments is which of the following?

Accepted Answer

The scientific study of the interaction between people, machines, and their work environments is referred to as human factors. Ergonomics, HCI, and usability are all sub-fields of human factors.

Question 11

Question 12

_________________________ is the study of how people design, implement, and evaluate interactive computer systems in the context of users' tasks and work.

Accepted Answer

The answer of _________________________ is the study of how people...

Question 13

Usability is a subset of HCI and one of its major components. Which of the following are usability topics?

Accepted Answer

Usability refers to how easy and efficient it is for users to interact with a system or application. Using an application (A), learning to use a system (B), and user satisfaction (C) are all important aspects of usability. Efficiency (D) and error-free/error-forgiving interactions (E) are also key components in ensuring a system is easy and effective to use. Therefore, all of the options given are usability topics.

Question 14

Ergonomics focuses on which of the following?

Accepted Answer

Ergonomics focuses on the physical design of work environments, equipment, and tasks to promote safety, comfort, and convenience. While A and B may fall under the category of ergonomics, they are specific examples rather than the overall focus. Choice C relates to benchmarking, which is not directly related to ergonomics.
