Answer 21

Factor
The timing of an analysis

Question 22

Evaluation Methods

Here are some of the factors that mainly affect user interface evaluation

Question 25

# **Evaluation Methods** Below are the different user interface (UI) evaluation methods:

Answer 25

* **Focus interview** * **Expert heuristic evaluation** * **Measurement**

Question 26

# **Evaluation Methods** — This is the easiest and most straightforward evaluation method, which involves an interview with the actual/potential user to observe their interaction behavior through a simple question and answer form.

Answer 26

* **Focus interview**

Question 27

# **Evaluation Methods** This method of evaluation is often focused on particular user groups and on a specific feature of the system or interface although this is not structured to be comprehensive. ## Footnote (e.g., college students and elderly) && (e.g., mode of input and information layout), (Kim, 2015).

Answer 27

* **Focus interview**

Question 28

# **Evaluation Methods** — This is an interview technique in evaluating the design of a user interface, with special attention to how well the interface supports exploratory learning for the target user.

Answer 28

○ *Cognitive walkthrough*

Question 29

# **Evaluation Methods** This evaluation method is done by having a subject or a group of evaluators go step by step through commonly used tasks.

Answer 29

○ *Cognitive walkthrough*

Question 30

# **Evaluation Methods** The evaluators can also perform it in the early stage of the design process ## Footnote (Usability.gov, n.d.).

Answer 30

○ *Cognitive walkthrough*

Question 31

# **Evaluation Methods** — This evaluation is similar to focus interview or observation study.

Answer 31

* **Expert heuristic evaluation**

Question 32

# **Evaluation Methods** The difference of this method is the involvement of human-computer interaction (HCI) experts as evaluators,

Answer 32

* **Expert heuristic evaluation**

Question 33

# **Evaluation Methods** and the analysis is carried out against a prepared HCI guidelines, hence the term `__________`.

Answer 33

* **Expert heuristic evaluation** *heuristics*

Question 34

# **Evaluation Methods** is fast and relatively cost effective; thus, it is one of the most popular methods in user interface evaluation.

* **Expert heuristic evaluation** Expert heuristic evaluation

Question 35

# **Evaluation Methods** Some examples of `__________` in evaluating are system status, display layout, ergonomics, consistency, error prevention, and help ## Footnote (Kim, 2015).

Answer 35

* **Expert heuristic evaluation** heuristics

Question 36

# **Evaluation Methods** — This method of evaluation intends to indirectly quantify the goodness of the interaction and interface design with the *numerical score* through task performance (quantitative) or quantified answers from a carefully prepared *subjective surveys* (qualitative).

Answer 36

* **Measurement**
