Question 1

user-centered design

Answer 1

Emphasizes involving end-users throughout the process to ensure systems and products are tailored to needs, preferences, and capabilities. Iteratively to create user-friendly and effective designs

Question 2

visibility and feedback

Answer 2

Systems should provide clear and timely feedback to users about their actions, helping them understand the system’s response. Visible indicators, auditory cues, and tactile feedback all contribute to improving user interactions

Question 3

consistency and standardization

Answer 3

Consistent design elements and standardized interfaces help users quickly
learn and operate new systems. Familiarity with common design patterns reduces cognitive load and minimizes errors

Question 4

Simplicity and minamilism

Answer 4

Design should prioritize simplicity and minimize complexity. Unnecessary features, options, or steps can confuse users and hinder usability. Keeping interfaces and interactions straightforward enhances user performance.

Question 5

error management

Answer 5

Design systems that prevent, detect, and recover from errors. This includes designing error messages that are clear and informative, as well as implementing safeguards to prevent catastrophic mistakes.

Question 6

affordances and signifiers

Answer 6

Affordances are cues in design that suggest how an object can be used. Signifiers are indicators that guide users on how to interact with a system. Effective use of affordances and signifiers improves user understanding

Question 7

human machine interaction

Answer 7

Design interactions that align with human cognitive and physical capabilities.
Consider factors such as memory limitations, attention span, reaction times, and motor skills when creating interfaces and interactions

Question 8

workload management

Answer 8

Design systems that distribute cognitive and physical workload effectively. Avoid
overwhelming users with too much information or complex tasks, and provide breaks and opportunities for recovery when needed

Question 9

task analysis

Answer 9

Break down tasks into subtasks and analyze the steps required to complete them. This helps in
identifying potential bottlenecks, inefficiencies, and areas where human factors can be optimized

Question 10

physical ergnomics

Answer 10

Consider anthropometric data (body measurements), biomechanics, and ergonomic
principles when designing physical environments, tools, and equipment. This ensures comfort, safety, and efficiency in various settings

Question 11

cognitive ergonomics

Answer 11

Address mental workload, decision-making, attention, memory, and learning capabilities of users when designing cognitive tasks and systems. Present information in ways that are intuitive and support mental processes

Question 12

human reliability

Answer 12

Design systems with redundancies and fail-safes to mitigate human errors, especially in safety-critical industries like aviation and healthcare

Question 13

aesthetics and emotion

Answer 13

Consider the emotional impact of design on users. Aesthetically pleasing designs can enhance user satisfaction and overall experience
