C & R Section 8.1 to 8.4 Augmented Reality

Augmented Reality (AR)

• AR is a technology that blends the digital world with the physical environment, overlaying digital information onto real-world surroundings.
• AR works by using computer vision, mapping, and depth tracking to generate content for the user.
• It uses cameras to collect and process data, sending the right content to the user in real-time.
• AR can be experienced with smartphones or special hardware.

Applications of AR

• Texting
• Embedding imagery and videos
• Printing
• Advertising and digital content
• Interpretation apps
• 3D tools for 3D real-time games

Virtual Reality (VR)

• VR is a fully immersive experience that allows users to undergo a real-world-feeling.
• VR systems use computer vision and advanced graphics to generate 3D images and videos by adding depth and reconstructing scale and distances between static 2D images.
• VR headsets with lenses and controllers enable users to explore and control 3D environments.

How VR Works

• VR uses a device like a special 3D video or image camera to create a three-dimensional world that a user can manipulate.
• The user sees a life-size image, creating the perception of being part of the simulation.
• VR hardware and software generate computer-generated 3D images and video, which are cast to a lens mounted on goggles or a headset.
• The user can use gaze control and controllers to select and browse through 3D content.

Applications of VR

• Enhancement of fictional realities in the gaming world
• Flight and battlefield simulation for military training
• Training device for PTSD and sports training
• Fear therapy through fictional or real-life scenes and scenarios
• Medical training for graduating students and to learn new skills in a safe environment

Difference between AR and VR

• VR creates an immersive virtual environment, while AR augments a real-world scene.
• VR is 75% virtual, while AR is only 25% virtual.
• VR requires a headset device, while AR does not.
• VR users move in a completely fictional world, while AR users are in contact with the real world.
• VR replaces the real world with the artificial, while AR enhances real life with artificial images.

What is Augmented Reality (AR)?

• AR is a technology that blends the digital world with the physical environment, overlaying digital information onto the real world.
• AR uses computer vision, mapping, and depth tracking to generate content for the user.
• AR enhances the user's physical environment in real-time using cameras that collect and process data.

Where is AR used?

• AR is used in texting, embedding imagery and videos, printing, advertising, and digital content.
• AR is used in interpretation apps and 3D tools for 3D real-time games.

What is Virtual Reality (VR)?

• VR is a fully immersive experience that allows the user to undergo a real-world-feeling.
• VR generates 3D images and videos by adding depth and reconstructing scale and distances between static 2D images.
• VR systems use computer vision and advanced graphics to produce real-life visual experiences.

How does VR work?

• VR uses a device like a special 3D video or image camera to create a three-dimensional world that a user can manipulate.
• VR hardware and software generate computer-generated 3D images and video, which are cast to a lens mounted on goggles or headset.
• The user can use gaze for the gesture to select and browse through the 3D content.

Where is VR used?

• VR is used in mainstream entertainment, gaming, and simulation for military training.
• VR is used in training devices for PTSD and sports training, fear therapy, and medical training.

Difference between AR and VR

• AR augments a real-world scene, while VR creates an immersive virtual environment.
• AR is 25% virtual, while VR is 75% virtual.
• AR does not require a headset device, while VR does.
• AR users are in contact with the real world, while VR users are in a completely fictional world.

Virtual Reality vs. Augmented Reality

• VR replaces the real world with the artificial, while AR enhances real life with artificial images.
• VR works well for games and social networking, while AR adds graphics, sounds, and smell to the natural world.
• VR uses head-mounted displays, while AR uses devices such as smartphones or wearable devices.

What hardware is used for Virtual Reality?

• The most common sensory displays are the computer visual display unit, head-mounted display (HMD), and headphones for 3D audio.
• 3D graphic cards, 3D sound cards, vector accelerator cards, and compressor accelerator cards are also used.

Is Virtual Reality a hardware or software?

• VR combines hardware and software to create immersive experiences that "fool" the eye and brain.
• Hardware supports sensory stimulation and simulation, while software creates the rendered virtual environment.
