A4 - Designing An Efficient User Interface

Multiple Choice

What is the primary purpose of keyboard shortcuts?

• Improve screen resolution

• Speed up input of instructions

• Replace the mouse entirely

• Increase security

Multiple Choice

Which shortcut selects all items in a document (as per the slide example)?

• Ctrl+C

• Ctrl+V

• Ctrl+A

• Ctrl+S

Multiple Choice

Which shortcut is used to undo an action?

• Ctrl+Y

• Ctrl+Z

• Ctrl+U

• Ctrl+R

Multiple Choice

The Left Arrow shortcut mentioned in the slide is associated with:

• Refresh

• Back

• Forward

• Close tab

Multiple Choice

The Right Arrow shortcut mentioned in the slide is associated with:

• Forward

• Back

• New tab

• Search

Multiple Choice

Why should excessive text be avoided in shortcut help overlays?

• It reduces icon size

• It slows page loading

• It overwhelms users and slows task flow

• It hides tooltips

Multiple Choice

What is the main goal of informative feedback?

• Entertain the user

• Confirm success/failure and guide the next action

• Replace error messages entirely

• Track user data

Multiple Choice

Which is the best example of informative feedback?

• A silent change on the screen

• A pop-up stating “Saved successfully” with a “View file” button

• A long paragraph about storage policy

• A pop-up with no close button

Multiple Choice

Why should feedback be clear and concise?

• To meet legal requirements

• To make text smaller

• To ensure users can quickly decide what to do next

• To improve colour contrast

Multiple Choice

Which format is explicitly mentioned for delivering feedback?

• Background image

• Pop-up

• Footer note

• Hidden tooltip

Multiple Choice

Adding links/buttons in feedback is useful because it:

• Hides the error details

• Moves users to unrelated pages

• Helps users take the next step immediately

• Forces page reload

Multiple Choice

Excessive feedback text can harm usability because it:

• Causes animations to fail

• Increases cognitive load and delays action

• Lowers device brightness

• Breaks hyperlinks

Multiple Choice

“Easy reversal of actions” primarily supports which usability principle?

• Aesthetic integrity

• Error tolerance/recovery

• Personalisation

• Hardware scalability

Multiple Choice

In the checkout example, why must users return to “Review Order”?

• To change the theme

• To edit an incorrect house number before confirming

• To update the device driver

• To change the currency symbol

Multiple Choice

Which control best supports easy reversal?

• Disabled “Back” button

• Clear breadcrumb trail

• Auto-playing video

• Hidden navigation

Multiple Choice

Allowing users to reverse actions improves:

• Marketing reach

• Network speed

• Confidence and error recovery

• Colour depth

Multiple Choice

A confirmation step before a destructive action (like “Delete”) helps by:

• Slowing the UI

• Forcing sign-out

• Reducing accidental irreversible actions

• Disabling shortcuts

Multiple Choice

Which is the worst practice for reversal of actions?

• “Undo” option

• Edit previous steps

• Breadcrumbs to earlier pages

• One-way wizard with no back option

Multiple Choice

Why must buttons/links stand out?

• To increase ad clicks

• So users recognise actionable elements quickly

• To allow bigger logos

• To reduce server load

Multiple Choice

A common convention for hyperlinks is that they:

• Use random colours

• Are underlined and change colour once visited

• Have no visual difference from text

• Use background videos

Multiple Choice

Which example best shows a distinguishable link?

• Grey text identical to body copy

• Underlined, high-contrast text that changes after visiting

• Small, low-contrast text

• Invisible hotspot area

Multiple Choice

What is a likely effect if links aren’t visually distinct?

• Faster navigation

• Users miss navigation paths

• Improved accessibility

• Better battery life

Multiple Choice

A “Help” button that looks like plain text most likely causes:

• Higher task success

• Lower discoverability

• Improved scanning

• Faster form completion

Multiple Choice

Which pairing follows convention for “Search”?

• Paintbrush icon

• Spanner icon

• Magnifying glass icon

• Heart icon

Multiple Choice

Why does object size matter on an interface?

• It sets the font license

• It affects how easily users can select items

• It controls cookie banners

• It determines file size

Multiple Choice

What happens if touch targets are too small?

• Users complete tasks faster

• Users waste time and have a poor experience

• Images load faster

• Shortcuts stop working

Multiple Choice

When designing for phones, you should especially consider:

• Mouse hover states

• Finger selection and screen size

• Keyboard macros

• Printer DPI

Multiple Choice

Which choice best improves selection accuracy?

• Smaller buttons with tight spacing

• Larger targets with adequate spacing

• Hidden buttons

• All caps labels

Multiple Choice

A likely consequence of difficult-to-tap controls is:

• Fewer errors

• Reduced bounce rate

• Increased mis-taps and abandonment

• Faster page loads

Multiple Choice

Which design review question comes directly from the slides?

• “What is the server OS?”

• “What will users need to select and how?”

• “What is the ISP bandwidth?”

• “What’s the paper size?”

Multiple Choice

Placing objects where users expect to find them improves:

• Aesthetics only

• Learnability and speed

• Server performance

• CSS validation

Multiple Choice

Why should common objects use expected icons?

• To reduce licensing fees

• To match user mental models and reduce search time

• To reduce pixel density

• To remove labels

Multiple Choice

Adjusting font, size, and colour of an object primarily helps with:

• Legal compliance

• Visual hierarchy and scannability

• Database performance

• Browser caching

Multiple Choice

Grouping related items together helps by:

• Increasing scroll length

• Reducing selection time

• Forcing longer reading

• Hiding advanced options

Multiple Choice

Which layout choice best follows the grouping principle?

• Scattering related controls around the page

• Grouping shipping, billing, and delivery options in one panel

• Splitting a form across random modals

• Hiding help beneath unrelated sections

Multiple Choice

The search icon should usually be:

• Magnifying glass

• A lock

• A heart

• A paintbrush
