Question 4

Independent variables is characteristic changed to produce different condition.Choose the example of Independent variables
i. Gender
ii. Interface style
iii. Task completion time
iv. Background noise
A)i, ii and iii
B)i, ii and iv
C)i, iii and iv
D)ii, iii and iv

Accepted Answer

Independent variables are those that are manipulated by the researcher to observe their effect on other variables. In this context, gender (i), interface style (ii), and background noise (iv) can all be manipulated or selected by the researcher to study their effects, making them independent variables. Task completion time (iii), however, is typically a dependent variable, as it is the outcome being measured and is expected to change in response to manipulations of the independent variables.

Question 9

Which is the best definition of an interface metaphor?
A)in broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., wimp, mobile, tangible)
B)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)
C)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)
D)the conceptual model used to guide the design of the interface.

Accepted Answer

An interface metaphor uses familiar ideas to help users understand how to interact with a computer system or software by drawing parallels between the operation of the digital interface and a physical or conceptual entity that the user already understands.

Question 10

To reconstruct a system, which of the following key element(s) must be considered :
A)outputs and inputs
B)control and processors.
C)feedback and environment
D)all of the above

Accepted Answer

To effectively reconstruct a system, it's essential to consider all its key elements: outputs and inputs (which define what the system takes in and what it produces), control and processors (which manage and execute the system's operations), and feedback and environment (which influence adjustments and how the system interacts with its surroundings). These components are integral to understanding and redesigning a system's functionality and interactions.

Question 11

Regarding paper prototypes:
A)low-fidelity paper prototypes are hand-drawn sketches and designed to be thrown away
B)high-fidelity paper prototypes look too much like a finished design.
C)high-fidelity paper prototypes are designed on-screen and then printed out in colour.
D)all of the above.

Accepted Answer

All of the statements are correct regarding paper prototypes. Low-fidelity prototypes are indeed hand-drawn and not meant for long-term use, high-fidelity prototypes can resemble finished designs closely, and they are often created digitally before being printed out to simulate a more complete version of the product.

Question 12

By using capitalized words, the reading speed and accuracy
A)increased
B)improved
C)declined
D)leveled

Accepted Answer

Capitalized words can disrupt the natural flow of reading, making it harder to recognize word shapes and patterns, which can lead to a decline in reading speed and accuracy.

Question 13

Which of these factors influence a user's conceptual model?
A)familiarity with similar devices.
B)constraints.
C)instructions.
D)all of the above

Accepted Answer

All of the factors listed - familiarity with similar devices, constraints, and instructions - influence a user's conceptual model by shaping their understanding and expectations of how a device or system works.

Question 14

If the user wants to ____________ place the document somewhere in the file system hierarchy, he can request this function from the menu.
A)explicitly
B)implicitly
C)habitually
D)properly

Accepted Answer

The correct choice is "explicitly" because it means to do something in a clear and direct manner. In the context of placing a document within the file system hierarchy, requesting this function from the menu would be a deliberate and explicit action by the user.

Question 15

Conventional wisdom says that tell the user when he has made some mistake.
A)program crash
B)system stuck
C)error messages
D)metadata

Accepted Answer

Conventional wisdom in user interface design and software development dictates that when a user makes a mistake, the system should provide error messages. These messages inform the user about the mistake and ideally offer a solution or guidance on how to correct it. This approach helps in maintaining a smooth user experience by preventing confusion and frustration.

Question 16

____________is the least technical way of collecting data, but it can be difficult and tiring to write and observe at the same time.
A)audio recording.
B)taking notes.
C)observation
D)video

Accepted Answer

Taking notes is considered the least technical method among the options given for collecting data. It can be challenging because it requires the researcher to manually write down observations, which can be difficult and tiring, especially when trying to observe and write simultaneously.
