Study Notes
AR vs. MR
- MR combines the best qualities of AR and VR to create an immersive interface that overlays on the user's reality.
- MR is an enhanced form of AR, where virtual objects are integrated into and responsive to the real world and can be manipulated by the user.
Statistics About AR/VR
- The video games sector is the highest user of AR/VR, followed by the Education & Healthcare sector.
Applications of AR/VR
- Medicine
- Training Applications
- Education
- Development Work (e.g., City Planning)
How Does VR Technology Work?
- VR systems simulate multiple senses to make the virtual environment feel real.
- The combination of hardware and software creates immersive experiences.
- Hardware supports sensory stimulation like sound, touch, smell, and heat intensity.
- Software generates the rendered virtual environment.
Hardware (VR Devices)
- Personal computer: processes inputs and outputs from users, consoles, and smartphones.
- Personal computer: renders high-quality graphics using Graphics Processing Units (GPUs) for faster computations.
Augmented Reality (AR)
- Layers computer-generated enhancements over an existing reality to make it more meaningful through interaction.
- Examples: Snapchat lenses, The game Pokemon Go.
What is AR/VR/MR?
Virtual Reality (VR)
- A realistic and immersive simulation of a three-dimensional environment.
- Created using interactive software and hardware, experienced or controlled by the movement of the body.
- Examples: VR PS5, Meta Quest.
Mixed Reality (MR)
- Users navigate through both real and virtual spaces at the same time.
- Virtual objects are hooked into the user's real world and augment their real environment.
- Examples: Microsoft's Hololens, Vision Pro by Apple.
Comparison 1: AR vs. VR
- AR uses a real-world setting while VR is completely virtual.
- AR users can control their presence in the real world; VR users are controlled by the system.
- AR apps can show up on and can be accessed with a smartphone or tablet while VR mostly requires a headset device.
- AR enhances both the virtual and real world while VR only enhances a fictional reality.
AR Hardware
- Sensors collect data from the physical environment and transmit it to an AR app (software).
- Modern mobile computing devices (smartphones, tablets) have features that make them suitable AR platforms, including:
- Camera
- GPS
- MEMS sensors (accelerometer, gyroscope, solid-state compass)
- Examples: Google Glass Explorer Edition, Microsoft HoloLens, and Vision Pro by Apple.
AR Software
- AR app developers use Apple ARKit and Google ARCore SDKs.
- Apple ARKit is used for iOS-based devices, while Google ARCore is for Android-based devices.
- The SDKs enable quick and easy creation of AR apps for smartphones and tablets.
Advantages of AR/VR
- In Training
- In Education
- In Entertainment and Gaming
- In Help & Healing
- In Architecture & Planning
Disadvantages of AR/VR
- Loss of Spatial Awareness
- Eye Soreness
- Seizures
- Nausea, Dizziness, and Disorientation
Challenges of AR/VR
- Price is too high
- Content is lacking
- Lack of viable business models
- Health effects
- VR perceived as a gimmick
- Ethical issues
- Social impact
