Augmented Reality (AR) and Augmented Virtuality (AV) are two distinct yet related concepts within the realm of mixed reality, representing different approaches to blending the real and virtual worlds.
Augmented Reality (AR)
AR enhances the real world by overlaying computer-generated images, sounds, or other sensory stimuli onto it. In essence, it augments our perception of reality.
- Focus: Real world as the primary environment.
- Technology: Typically uses devices like smartphones, tablets, or specialized AR glasses to project virtual elements onto the user's view of the real world.
- Examples:
- Pokémon GO: Overlays virtual Pokémon characters onto the real-world environment seen through a smartphone camera.
- IKEA Place: Allows users to virtually place furniture in their homes using their smartphone camera to see how it would look.
- AR-enhanced medical visualizations: Superimposing 3D images of organs onto a patient's body to aid in surgery.
- Key Characteristic: Adds virtual elements to a real-world view.
Augmented Virtuality (AV)
Augmented Virtuality, also known as mixed reality (MR), primarily takes place in a virtual world, but incorporates real-world objects or information into that virtual environment. AV augments a virtual environment with real-world elements.
- Focus: Virtual world as the primary environment.
- Technology: Often involves using sensors and tracking technologies to bring real-world objects or people into a virtual space. Can leverage headsets that support see-through capabilities or depth sensing cameras.
- Examples:
- Virtual training simulations: Allowing users to interact with virtual machinery while using real-world tools, with their actions being reflected in the virtual environment.
- Telepresence robots: Allowing users to interact with remote locations and people through a virtual interface where real-time video and audio feeds are integrated.
- Virtual design software: Allowing architects to incorporate real-world constraints, like sunlight angles or material properties, into their virtual designs.
- Key Characteristic: Adds real-world elements to a virtual view.
Key Differences Summarized
Feature | Augmented Reality (AR) | Augmented Virtuality (AV) |
---|---|---|
Primary World | Real World | Virtual World |
Functionality | Adds virtual to real | Adds real to virtual |
User Perception | Real world enhanced | Virtual world enhanced |
In essence, AR brings virtual elements into the real world, while AV brings real-world elements into a virtual one, both contributing to the broader spectrum of mixed reality experiences.
