Questions and Answers

What is the main difference between Virtual Reality (VR) and Augmented Reality (AR)?

VR provides access to real-time information, while AR creates a three-dimensional environment.

AR completely encases the user's face, while VR allows users to see their surroundings.

VR allows users to interact with physical objects, while AR only provides visual and audio information.

VR creates a completely simulated environment, while AR superimposes images and audio over the real world. (correct)

How do VR headsets differ from AR headsets in terms of ambient light?

VR headsets allow ambient light in, while AR headsets create a completely dark environment for users.

Both VR and AR headsets allow ambient light to enter, providing a more immersive experience.

AR headsets block out all ambient light, while VR headsets enable users to see their surroundings clearly.

Study Notes

Virtual Reality (VR) vs. Augmented Reality (AR)

VR creates a completely immersive digital environment, while AR overlays digital elements onto the real world.
VR headsets block out ambient light for a fully immersive experience, whereas AR headsets allow ambient light in to blend digital content with the real world.

Technology Features

AR technology superimposes images and audio over the real world in real-time, enhancing the user's perception of their environment.

Printer Functions

The primary function of printers is to produce physical copies of digital documents and images.
Printers communicate with the operating system through a specific component known as a print driver.

Digital Light Processing (DLP)

DLP technology is used in projectors and televisions to produce high-quality images with better color and brightness control.

Output Devices

VR headsets serve as the primary output device for immersive gaming and training experiences.
Speakers function as output devices by converting electrical signals into sound.
Printers are the primary output device used for producing physical, printed documents.
Headphones deliver audio output directly to the user, enhancing personal listening experiences.

Input Devices

Facial recognition technology utilizes unique facial features for user identification, enhancing security measures.
Voice recognition technology identifies users through unique voice patterns, allowing for hands-free operation.

Adapters and Controllers

The main function of an adapter is to enable compatibility between different devices or formats.
A KVM (Keyboard, Video, Mouse) switch allows control of multiple computers using a single keyboard, monitor, and mouse.
A DVI to HDMI adapter converts DVI signals to HDMI format, facilitating connection between devices with different output types.
A Molex to SATA adapter provides power from older Molex connectors to newer SATA drives.

Gaming Input Devices

Game controllers are commonly used input devices for playing video games, offering tactile feedback and controls for gameplay.
