• Keyboard

• Monitor

• Touchscreen

Which of these is a common output device in HCI?

• CPU

• Keyboard

• Speaker

• Touchscreen

What does the CPU do in the context of HCI?

• Collects data from input devices

• Processes user inputs and provides results

• Displays information to the user

• Stores input data

The evolution of HCI shows that early computers (1940s-1970s) were primarily limited to what type of interaction?

• Graphical user interface (GUI)

• Command-line interaction

• Voice control

• Gesture-based interaction

What was the significant development in HCI during the 1980s-1990s?

• Introduction of voice assistants

• Introduction of graphical user interfaces (GUIs)

• Rise of touchscreen interaction

• Introduction of artificial intelligence

What type of interaction did the rise of touchscreen and mobile devices (2000s) bring about?

• Voice interaction

• Touch and gesture-based interaction

• Direct manipulation

Which HCI interaction method involves users interacting directly with objects on the screen?

• Gestural Interaction

• Voice Interaction

What defines a Command-Line Interface (CLI) in HCI?

• Uses graphics to interact with the user

• Relies on text-based commands

• Responds to voice commands

• Uses physical gestures to control the system

Which interaction method uses physical gestures to control the system?
