Virtual Reality Design Terminology

Below is a curated list of terms relating to design within virtual reality.

  • avatar

    a virtual representation of the experiencer within the virtual world

    They are the audiovisual bodies that people use to communicate with each other in the Metaverse.1

  • butterfly effect system

    the butterfly effect system is a storytelling mechanism for managing complex narrative structures where actions from the experiencer can have a direct influence on how the narrative plays out

    The phrase ‘butterfly effect’ derives from chaos theory where American mathematician Edward Norton Lorenz used it as a metaphor to describe the phenomenon whereby a minor change in circumstances can cause a large change in outcome.

  • cockpit

    a virtual anchor that is fixed to the experiencer’s view and helps to ground them in the virtual world e.g. a fighter jet cockpit

    Research has shown that grounding the experiencer’s with virtual anchors can help curb symptoms of virtual reality sickness.

  • dollhouse view

    a top-down, external view of the entire artificial space allowing the designer to make global decisions about its composition and to enable swift prototyping

    The dollhouse view can also be combined with a first-person POV, to allow the experiencer to occupy the space they are actively manipulating, avoiding the need to switch between modes and perspectives when designing the space.

  • field of view (FOV)

    is the view that is visible to the experiencer while rotating their head from a fixed body position

    The average human field of view is approximately 200 degrees.

  • gaze-activated content

    when content e.g. the way actors within a scene behave, or the narrative, is directly impacted by the experiencer’s gaze

    See Believe VR from LA-based VR filmmaker Kevin Cornish and AMD.

  • hotspot

    an interactive spot within the artificial experience that reveal more content or options

    Hotspots can be animated and are often shown as a glowing orb.

  • occlusion

    the obscuring or hiding an object from view by the positioning of other objects in the experiencer’s line of sight

  • pitch

    rotation around the horizontal (x) axis

  • quillustration

    creating dynamic, 3D animations and illustrations in virtual reality using the Oculus Quill

  • reticle

    the reticle is a visual aid for the experiencer to target objects within a virtual reality environment with their gaze

  • signposts (signposting)

    environment cues with the added purpose of helping the user to interpret the virtual environment

  • yaw

    rotation around the vertical (y) axis
