Lecture 3 - Part 2

What is the first of the Eight Golden Rules of Interface Design according to Shneiderman?

• Prevent errors

• Seek universal usability

• Strive for consistency

• Reduce short-term memory load

Which of the following is an example of reducing short-term memory load in user interfaces?

• Using identical terminology in prompts

• Avoiding re-entry of information in lengthy forms

• Offering step-by-step instructions for solving errors

• Organizing actions into groups with a beginning, middle, and end

What does the rule “Design dialogs to yield closure” focus on?

• Preventing user errors

• Making user actions reversible

• Grouping actions into a sequence with a clear outcome

• Providing multiple ways to complete tasks

According to the Nielsen and Molich guidelines, what should designers do to help users recover from errors?

• Provide a clear undo option

• Make the system respond faster

• Use consistent icons

• Highlight recommended options

What is Hick’s Law in the context of interface design?

• Reducing short-term memory load by recognizing user inputs

• The time to make a decision increases with the number of choices

• Offering users multiple ways to perform an action

• Organizing actions into logical sequences

Which principle emphasizes that user interfaces should use concepts familiar to users from the real world?

• Consistency and standards

• Recognition rather than recall

• Match between system and the real world

• Prevent errors

What is the primary purpose of the principle 'Offer information feedback'?

• To simplify the user interface

• To provide feedback for user actions

• To reduce the complexity of tasks

• To allow users to undo actions

The cognitive load in a user interface refers to:

• The speed at which the system responds to user actions

• The amount of memory the system uses

• The mental resources required to operate the system

• The time it takes for users to make decisions

Which design principle advises minimizing unnecessary information on a user interface to focus on relevant tasks?

• Strive for consistency

• Flexibility and efficiency of use

• Aesthetic and minimalist design

• Keep users in control

According to Jakob’s Law, how should designers create websites?

• Provide detailed documentation

• Ensure that their website functions like other familiar sites

• Simplify choices for users

• Avoid using colors similar to other websites
