augmented reality (AR)

by MotionBrothers

in augmented reality (AR) the visible natural world is overlaid with a layer of digital content

The differences between VR, AR, and MR are best summed up by quote attributed to Clay Bavor:

VR is the power to take you anywhere, MR and AR is the power to bring anything to you

CAVE

by MotionBrothers

a CAVE (cave automatic virtual environment) is a virtual reality environment made up of between three and six walls that form a room-sized cube

Projectors display a virtual world onto the interior walls of the CAVE and are then controlled by the movement of an experiencer from within the CAVE.

haptics

by MotionBrothers

haptic technology simulates the sense of touch through the sensation of pressure (usually on the hands via a glove)

This helps to support agency by enabling the experiencer to control virtual objects or sense physical forces within the virtual environment. Haptics are a significant component in peripherals.

latency

by MotionBrothers

the time delay or lag between activating a process (change in input from the experiencer) and its accomplishment (the visual effect)

High-latency can lead to a detached experience and can also contribute to motion sickness / dizziness.

locomotion

by MotionBrothers

refers to the process of moving from one place to another

This is most commonly used to refer to movement within the virtual environment e.g. how an avatar navigates the virtual world, but can also refer to movement outside of the virtual environment e.g. how the experiencer navigates the real-world while in a virtual experience.

Locomotion mechanics in virtual reality can be broken down into three primary categories:
1. Perambulation
2. Teleportation
3. Transportation

mixed reality (MR)

by MotionBrothers

mixed reality (MR) is similar to augmented reality (AR) except virtual objects are integrated into the natural world

For example, a virtual ball beneath your desk would be blocked from view unless you bent down to look at it.

The differences between VR, AR, and MR are best summed up by quote attributed to Clay Bavor:

VR is the power to take you anywhere, MR and AR is the power to bring anything to you

Computer game designer Graeme Devine, now Chief Creative Officer at Magic Leap, describes mixed reality as:

Mixed reality is the mixture of the real world and virtual worlds so that one understands the other. This creates experiences that cannot possibly happen anywhere else.1

peripheral

by MotionBrothers

a device that helps enhance a virtual reality experience by enabling greater immersion within the virtual world

The most common VR peripherals are gloves or controllers e.g. the Oculus Touch that look to mirror the experiencer’s innate movements and help to facilitate better active presence.

Other VR peripherals include those looking to simulate real-life objects or apparatus e.g. bikes (VirZoom), weapons (PS VR Aim, The VR-15 from VRsenal), shoes (Taclim). Peripherals can also be classed as devices that help enhance the environment e.g. candles.

positional audio

by MotionBrothers

audio that is triggered based on the position of the headset

For example, in a crowded scene the experiencer would be given the ability to choose which conversation they listen to based on where they are looking.

New Wave by Directors Samir Mallal and Aron Hjartarson demonstrates the positional audio approach.
