This set of Usability Engineering Multiple Choice Questions & Answers (MCQs) focuses on Usability Engineering Set 11
Q1 | Which of the following is a design implication of our understanding of human attention?
- tactile feedback should make the same kinds of distinctions that a
person would feel in the world (e.g. pushing vs. pulling) - text should be legible and distinguishable from its background under
different lighting conditions. - avoid cluttering the interface with more information than is needed at
the present moment for the user. - none of the above.
Q2 | Regarding gear-up accidents:
- pilots frequently lowered the landing gear instead of the flaps after take- off.
- lt. alphonse chapanis dicovered the cause of the problem in 1975.
- the flap control knobs were replaced by beer tap handles.
- shape-coded wheel and flap controls are still used today.
Q3 | Mental model is a/ an _ of a device or a system
- summary of the characteristics of users
- estimate of mental level of users
- human representation of the conceptual structure
- investigation results about mental characteristics of users
Q4 | Which of the following techniques can teach you afew things about a thousandpeople?
- cognitive walkthrough
- market researchy
- affinity diagram
- contextual inquir
Q5 | Independent variables is characteristic changed to produce different condition.Choose the example of Independent variablesi. Genderii. Interface styleiii. Task completion timeiv. Background noise
- i, ii and iii
- i, ii and iv
- i, iii and iv
- ii, iii and iv
Q6 | Choose the suitable method to apply the criteria below: Data can be collected in database for analysisPresent result clearly Responses are usually received quickly
- interview
- questionnaire
- research
- observation
Q7 | Using model of how a human would use a proposed system to obtain predict usability measure by calculation or simulation."Choose the evaluation technique to describe the above statement
- heuristic evaluation
- cognitive walkthrough
- model-based evaluation
- review-based evaluation
Q8 | Panes, frames and other containers on screen is a kind of
- functional and data elements
- view
- input method
- none of the given
Q9 | is particularly useful early in design. It is excellent technique to use with the prototype, because it provides a wealth of diagnostic information
- co-discovery
- active intervention
- splendid research
- none of the given
Q10 | Which is the best definition of an interface metaphor?
- in broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., wimp, mobile, tangible)
- an idea from the world that is used in the interface to help the user understand what to do (e.g., click on tabs to change window contents, use shopping cart to store items to purchase)
- what the human does to make inputs and receive information from the system (e.g., click and drag an object, talk to an object, move self closer to an object, converse with an entity, etc)
- the conceptual model used to guide the design of the interface.
Q11 | To reconstruct a system, which of the following keyelement(s) must be considered :
- outputs and inputs
- control and processors.
- feedback and environment
- all of the above
Q12 | Regarding paper prototypes:
- low-fidelity paper prototypes are hand-drawn sketches and designed to be thrown away
- high-fidelity paper prototypes look too much like a finished design.
- high-fidelity paper prototypes are designed on-screen and then printed out in colour.
- all of the above.
Q13 | By using capitalized words, the reading speed andaccuracy
- increased
- improved
- declined
- leveled
Q14 | Which of these factors influence a user’s conceptualmodel?
- familiarity with similar devices.
- constraints.
- instructions.

Q15 | If the user wants to place the document somewhere in the file system hierarchy, he can request this function from the menu.

- implicitly
- habitually

Q16 | Conventional wisdom says that tell the userwhen he has made some mistake.
- program crash

- audio recording.
- taking notes.
- observation
- video
Q18 | Research can tell you about what, how, many and why in rich, multivariate detail.
- quantitative
- qualitative
- sme
- none of these
Q19 | What was an important early drawback of the Clearboard system by Ishii et al. (1993).
- it required people to move to a dedicated video conferencing facility at their workplace
- as people moved closer to the board to talk with a remote colleague, the video system no longer picked them up
- people found it uncomfortable to interact “looking down” at a colleague.
