Virtual reality (VR) technology creates immersive three-dimensional simulations where users can interact with specialised equipment like headsets and sensor-fitted gloves. This cutting-edge technology is revolutionising various fields, including gaming, education, healthcare, and training simulations. It offers users a more realistic and interactive experience compared to traditional interfaces.
Augmented reality (AR) overlays computer-generated images and information onto the real world, typically viewed through the screen of a smartphone, tablet, or AR headset. Unlike virtual reality (VR), which replaces the real world with a simulated one, AR enhances the real world with digital information. It offers various applications in gaming, marketing, education, and training. For example, AR technology can enable the application of filters, lenses, and games like Pokemon Go, as well as retail features e.g. trying on glasses or visualising products in spaces e.g.trying out a chair in your lounge room.

| Characteristic | Virtual reality (VR) | Augmented reality (AR) |
|---|---|---|
| User experience | VR completely immerses users in a simulated environment, disconnecting them from the physical world. | AR integrates virtual content with the real world, which enhances the user's perception of reality in the physical world. |
| Interaction with the environment | VR restricts interaction to only the virtual environment and requires specialised controllers or hand-tracking devices | With AR, individuals can engage with virtual and physical objects in their real world environment |
| Hardware requirements | VR experiences often require a dedicated VR headset with controllers and other sense-tracking devices. | AR experiences can be accessed through smartphones, tablets or specialised AR glasses |
