Moving in VR: How does it work?

One of the most crucial aspects of the virtual reality experience, aside from interactions, is the way users move within the digital world. The right methods of navigation can significantly impact immersion, comfort, and the overall functionality of an application. There are various ways to move in VR, ranging from free walking to advanced omnidirectional treadmills.

 
Free Movement

The most intuitive method of moving in VR is free walking. The user physically moves in the real world, and the VR headset replicates these movements within the virtual environment. This type of movement requires an appropriate area (a safe zone) to be defined before starting the session. Proper setup alerts the user when approaching the boundary, reducing the risk of colliding with objects outside it, such as a chair or a wall. Free movement feels natural and fully immersive, but it’s important to note that it is limited to the size of the physical space the user occupies.

Teleportation

Teleportation is a popular method of movement, especially in applications where the user’s goal involves performing manual tasks or traversing large distances in the virtual world. The user points to a desired location, usually with a controller, and their avatar is “teleported” to the selected spot.

This method offers several key advantages. First, it minimizes the risk of motion sickness, which can occur with other movement techniques. Second, teleportation is user-friendly and does not require a large physical space. However, its limitation lies in reduced immersion, as teleportation allows users to cover significant distances instantly, which can feel less natural compared to free movement.

Omnidirectional Treadmills

Omnidirectional treadmills represent the most technologically advanced solution for movement in VR. They enable users to walk, run, and perform more complex movements like turning or pivoting in any direction.
These devices allow for full immersion by eliminating the limitations of physical space. Users stand on the treadmill and often wear specialized shoes or harnesses that keep them securely in place while enabling movement in all directions.
While omnidirectional treadmills offer the most realistic VR movement experience, their main drawbacks include high costs and the need for a dedicated installation space, which can sometimes undermine the advantages of wireless VR headsets.

Choosing the right method of movement

The choice of movement method in VR depends on the application’s purpose and user needs. Free movement works best in small spaces and more static applications. Teleportation is ideal for games, simulations, or educational applications where users need to explore a virtual world. Meanwhile, omnidirectional treadmills are the choice for those seeking full immersion and unlimited mobility.
