Locomotion
Locomotion is moving through a virtual world in VR.
Aside from traditional control peripherals like mouse, keyboard and gamepad, the most obvious method of locomotion is simply walking around within the range of the positional tracking gadgets.
One problem presented by "walking" is the available space of the room. Physical obstacles such as walls and objects will prevent the user from advancing.
One solution to this problem is a omni-directional treadmill such as Omni. Another option is to use teleportation or elevators to virtually transport the user to a new environment while keeping the physical space the same.
Turning[edit]
A Smooth Turn, also sometimes referred to as Continuous Turn, is a movement style in virtual reality. When the user attempts to turn his character through the use of a button or some other control, their character's view gradually shifts in the desired direction. Vignetting may be used. In some VR content, this is a feature that can be turned on or off, or adjusted as to how quickly the turn will occur. A high-speed turn can reduce motion sickness.
A Snap Turn, also sometimes referred to as Click Turn, Incremental Turn, or Blink Turn, is a movement style some VR creators offer in their VR content. In an effort to reduce potential motion sickness, when the user attempts to turn their character through the use of a button or some other control, their character will "instantly" turn by a pre-determined amount. Often a value like 15 degrees, 30, 45, or 90 degrees. The turn may happen with an instant view shift, or the view may turn gradually but extremely quickly (to avoid motion sickness), or Vignetting may be used. In some VR content, this is a feature that can be turned on or off, or adjusted as to how many degrees and how quickly the turn will occur.
