Quiz on Direct Manipulation in HCI

What is the main characteristic of direct manipulation in HCI?

• Minimal user feedback

• Immediate visual representation of actions

• Complex command syntax

• Reliance on text-based interfaces

Which of the following is an example of an invisible interface?

• Touchscreen on a smartphone

• Voice assistant like Alexa

• A keyboard shortcut

• A file explorer window

What does the term “invisible interface” primarily refer to in HCI?

• A transparent interface

• An interface that minimizes user interaction by working seamlessly in the background

• An interface visible only in AR/VR environments

• A complex interface requiring training

Which of the following is NOT a principle of direct manipulation?

• Continuous representation of objects

• Physical actions instead of complex syntax

• Instant feedback for each action

• Relying on command-line instructions

An elevator that uses voice commands instead of physical buttons is an example of:

• Command-line interface

• Invisible interface

• Direct manipulation

• Augmented reality

What is the primary benefit of direct manipulation interfaces?

• Faster task execution with minimal errors

• High learning curve for new users

• Increased dependence on keyboard shortcuts

• Complex workflows with more steps

In which scenario is direct manipulation commonly used?

• Writing a script for automation

• Dragging and dropping files into a folder

• Using a voice command to turn on lights

• Navigating through a terminal

Which principle of invisible interfaces makes them efficient?

• Reliance on large visual elements

• Functionality integrated seamlessly into the user’s natural actions

• High dependence on graphical interfaces

• Requirement for user training before usage

A touchscreen interface where users swipe to unlock is an example of:

• Command-based interface

• Direct manipulation

• Invisible interface

• Menu-driven interface

Which of the following is a drawback of direct manipulation interfaces?

• They are hard to learn for new users

• They may become cluttered with too much information

• They provide slow feedback to user actions

• They are incompatible with graphical interfaces
