Reality-Virtuality continuum

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

• AR uses real-world settings while VR is completely virtual.

• VR uses real-world settings while AR is completely virtual.

• AR and VR are the same.

• Neither AR nor VR uses real-world settings.

Virtual Reality can only be experienced through visual and auditory senses. True or False?

• True

• False

Answer explanation

Virtual Reality can also include other sensory feedback like touch (haptic feedback).

__________ is a technology that overlays digital information on the physical world.

Which of the following is an example of a VR interface?

• Smart glasses

• Haptic gloves

• Smartphone AR app

• Projection mapping

In a fully immersive VR experience, a user can interact with the virtual environment in a physical way. True or False?

• True

• False

Match the following technologies to their correct descriptions:

• Provides tactile sensations

• Augmented Reality

• Enhances real-world environments

• Haptic Feedback

• Completely immersive experience

• Virtual Reality

Describe how user interfaces in virtual environments differ from traditional user interfaces in computing.

Answer explanation

User interfaces in virtual environments are often 3D and spatial, allowing for interaction through gestures, motion tracking, and voice commands, as opposed to traditional 2D interfaces that rely on peripherals like a keyboard and mouse.

Discuss the potential impacts of virtual reality technologies on education and training. Provide examples.

Answer explanation

The answer should include points like immersive learning experiences, practical training simulations (like surgical procedures for medical students, or machinery operation for engineering students), enhanced engagement, and the possibility of experiencing scenarios that are impossible or impractical in the real world.
