Understanding Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)
Virtual reality (VR) is a technology that immerses users in a completely digital environment, allowing them to interact with a 3D space as if they were physically present in it. Users typically wear a VR headset that covers their eyes and often includes sensors that track their movements, enabling them to look around and move within the virtual world. An example is VR simulations used for training, such as flight simulators for pilots. These programs allow trainees to practice flying an aircraft in a safe and controlled virtual environment, giving them the opportunity to experience realistic scenarios without the risks associated with actual flying.
Augmented reality (AR) is a technology that enhances the real world by overlaying digital information—such as images, sounds, or text—onto the user’s view of the physical environment. This allows users to interact with both real and virtual aspects simultaneously. An example is the IKEA Place app, which allows users to see how furniture would look in their home. By using their smartphone camera, users can place virtual furniture in their living space and visualize it in real size before making a purchase, helping them decide on the best fit for their rooms.
Mixed reality (MR) is a technology that combines elements of both virtual reality (VR) and augmented reality (AR), allowing digital and real-world objects to coexist and interact in real time. In mixed reality, users can see and interact with both physical environments and virtual elements, creating a more immersive experience. A popular example of mixed reality is the Microsoft HoloLens. With HoloLens, users can see and interact with holographic images while still being aware of their physical surroundings. For instance, a user wearing HoloLens might see a virtual 3D model of a car or a machine overlaid on their real workspace. They can manipulate the virtual model, rotate it, or even walk around it to get a better view, while still interacting with their actual physical environment. This technology is particularly useful in fields like architecture, medicine, and education, where users can visualize and interact with complex data and models directly in their real-world contexts.
