From the degree of control users have over their surroundings to the way sensory inputs are handled, AR and VR craft unique paths to experience digital content that cater to varying levels of immersion and integration with the real world.
Environmental Control
Virtual Reality immerses users in an entirely constructed space, making the technology ideal for environments where every detail is system-driven. Whether it’s an open-world game, a flight simulator, or an educational program, the user fully surrenders environmental control to the VR system.
Once the headset is on, the physical world fades away, replaced by a digital realm that the system governs entirely. This creates a boundary between the user and their physical surroundings, isolating them to allow for complete immersion.
While this level of control heightens escapism and focus, it also restricts the user’s ability to multitask or remain connected to the external environment.
In contrast, Augmented Reality allows users to maintain control over their physical surroundings, layering digital content seamlessly into the real world. AR users are not transported to a separate space; instead, they stay grounded in their immediate environment while interacting with virtual elements that enhance real-world contexts.
This fluid integration lets users engage with digital tools without losing awareness of their physical presence. For example, AR can provide navigational assistance on a busy street while users remain fully aware of their surroundings, creating a balance between immersion and practicality.
