Second 25 questions HCI

For large implementation projects, the customer or manager usually sets objective and measurable goals for hardware and software performance. If the completed product fails to meet defined acceptance criteria, the system must be reworked until success is demonstrated. What do we call this test? A. Acceptance Test B. User survey C. Usability testing D. Cognitive walkthrough

Acceptance Test

___________ is reasonably comprehensive expert analysis, focused on psychological aspects of interface. Specifically, it focuses on understanding how well the interface supports "exploratory learning," i.e., first-time use without formal training. It involves one or a group of evaluators inspecting a user interface by going through a set of tasks and evaluate its understandability and ease of learning.

Cognitive walkthrough

_________ is more formal analysis based on code walkthroughs. Specifically, it evaluates a user interface in terms of identifying graphics, text, and interaction discrepancy. A. Heuristic evaluation B. Guidelines review C. Consistency inspection D. Cognitive walkthrough E. Formal usability inspection

Consistency inspection

___________ is more formal analysis, based on code walkthroughs. In this evaluation method, expert(s) are asked to inspect consistency within an application. Evaluating and improving a user interface is performed both within a screen and between screens, in graphics (color, typography, layout, icons), text (tone, style, spelling), and interaction (consistency of task steps and command names).

Consistency inspection

_______________ is usually considered as a theoretical framework. But, it is broadly applied to scientific experiments because it can produce more fundamental results and support perceptual, cognitive, and motoric theories. Utilizing the experiments is often considered in user interface design because it can lead to a deeper understanding of the fundamental principles of human interaction with computers. It also can help fine tuning the human-computer interface of actively used systems.

Find the one that does not have correct description about expert reviews? A. Heuristic evaluation is the most informal method and involves having usability specialists judge whether each dialogue element follows established usability principles (the "heuristics"). B. Cognitive walkthrough uses a more explicitly detailed procedure to simulate a user's problem-solving process at each step through the dialogue, checking if the simulated user's goals and memory content can be assumed to lead to the next correct action. C. Pluralistic walkthrough uses group meetings where users, developers, and human factors people step through a scenario, discussing each dialogue element. D. Consistency inspection has designers who represent multiple other projects inspect an interface to see whether it does things in the same way as their own designs. E. Formal usability inspection combines individual and group inspections in a six-step procedure with freely defined roles to with elements of both heuristic evaluation and a simplified form of cognitive walkthroughs.

Formal usability inspection combines individual and group inspections in a six-step procedure with freely defined roles to with elements of both heuristic evaluation and a simplified form of cognitive walkthroughs.

The evaluation process requires that a small set of testers (or "evaluators") examine the interface, and judge its compliance with recognized usability principles (the "heuristics").

Expert reviews can be scheduled at several points in the development process when experts are available and when the design team is ready for feedback. ÿ C. Inviting one or two expert reviewers would be sufficient enough for initiating expert reviews. D. Even experienced expert reviewers have great difficulty knowing how typical users, especially first-time users will really behave.

Inviting one or two expert reviewers would be sufficient enough for initiating expert reviews.

Identify the one that has an incorrect explanation about heuristic evaluation. A. It is a usability inspection method for computer software that helps to identify usability problems in the user interface (UI) design. B. It is performed by having more than one evaluators inspect the interface alone. C. It is a discount usability engineering method for quick, cheap, and easy evaluation of a user interface design. D. It is a form of usability inspection where usability specialists judge whether each element of a user interface follows a list of established usability heuristics.

It is performed by having more than one evaluators inspect the interface alone.

Describe how User Testing is far more accurate than Heuristic Evaluation.

It takes into account actual users and tasks. HE may miss problems & find "false positives"

Participants should not be chosen to represent the intended user communities.

Participants should not be chosen to represent the intended user communities.

Explain the difference between plagiarism and copyright infringement?

Plagiarism is not a legal term. It is a term for an academic crime, usually defined by professional or academic bodies. Simply stated, a plagiarist is a person who poses as the creator of words, ideas or methods that are not his own. By contrast, a person infringes on another's copyright when he makes unauthorized use of material that is protected by copyright.

E. Usability testing has become an established and accepted part of the design process.

The design team needs not to be involved with research on the current system design drawbacks.

In usability testing, think aloud protocol is often used to understand what participants are doing as they are performing the task. Explain the think aloud protocol?

Think-aloud (or thinking aloud) protocol (also talk-aloud protocol) is a protocol used to gather data in usability testing. Think-aloud protocols involve participants thinking aloud as they are performing a set of specified tasks. Participants are asked to say whatever comes into their mind as they complete the task. This might include what they are looking at, thinking, doing, and feeling.
