Accessibility: Theatre Experiences for Everyone
One of the inherent challenges of working within a primarily visual medium, such
as VR or AR, is the necessary recognition that those with visual impairments might
only partially engage with the visual imagery, if at all. With this in mind, the creator
of the VR and/or AR elements may choose to take advantage of the spatial audio
support built into many available VR or AR devices. The inclusion of precisely localized sound "cues" can provide interactive potential and useful contextual information a participant might have been missed visually. If planned for and implemented
properly, spatial sound effects during the flying monkey example may provide an
effective vehicle for interaction.
Looking at the benefits VR and AR can provide to specific populations opens
up several amazing possibilities. One obvious benefit of sharing theatre through VR
is the ability to participate in the experience from practically anywhere. If one's own
home provides a comfortable and secure environment for audience members who
find a crowded venue prohibitive to their enjoyment of the theatre, they now have
that option. The same could be said for those physically unable to make it to the
theatre, whether for reasons of mobility or simply geographic proximity.
At the National Theatre in London, AR is already providing hearing impaired
patrons with the option of viewing subtitles via "smart caption" glasses. Throughout
the performance, the glasses superimpose captions into the user's view in the location, size, and color of their choice. While this particular system doesn't assess any
spatial relationship between the viewer and the performers, it lays the groundwork
for achieving spatially aware captions that track with the appropriate actor, floating
just above their head similar to a speech bubble.

in medical training for exploring detailed
anatomy and visualizing surgical procedures, AR apps can also train radiology
techs on the operation of MRI machines.
Similarly, maintenance technicians for
air, land, and sea vehicles are using the
technology to follow superimposed visual prompts that guide them through
each step of the repair. Although these
use-cases may seem far afield from putting the beat-down on flying monkeys,
their contribution to the advancement
of sensor, display, processor, and battery
technologies is a tide that lifts all AR
boats. In fact, Digi-Capital predicts AR
will represent quadruple the revenue of
VR in 2020. While AR hardware manufacturers have taken note of VR's hype
problem, this figure likely represents an
optimistic timeline for mainstream adoption of the technology. In the short history of AR eyewear, companies have been
universally behind schedule on achieving
stated hardware goals. Though these
hardware and software tools may be
slow to develop, the potential of AR for
live performance design is staggering.
High-quality, spatially aware, digital objects that react to user input will allow

personalized AR experiences to become
an integrated part of live performances,
and a new medium for theatre designers. Consider the following regarding
devices:
■ Eyewear. The ideal Wizard of Oz production scenario presented above describes the holy grail of AR devices:
eyewear that is intuitive, comfortable,
and creates an experience so captivating it feels like magic. This device
would necessarily incorporate a small
form factor with powerful sensors and
processing, high-quality wide Field of
View (FOV) displays, and loads of battery life.
■ Data Transmission. With the proliferation of the 5G wireless transmission protocol well underway, the
sheer volume of data that streaming high-quality VR footage requires
could certainly utilize the enhanced
bandwidth. In addition to the potential for 20x the data transmission rate
of 4G, 5G has the potential to reduce
latency into sub-millisecond range,
allowing offloading of processes that
used to be handled by the device itself.
In the short-term, this enhanced VR

streaming experience may be limited
to users located in large population
centers where wireless carriers see
the most return on their investment;
it's not cheap to add a 5G "cell" every 500 feet. Rural cities will likely
have to wait a while for 5G to come to
town. Still, theatrical AR experiences
located anywhere can still leverage
the low-latency 5G platform to create
speedy connections between an AR
app and a server, or servers, on a local network. In this way, a computer
in the room can locally process and
control an audience of AR devices.
Ideally, this method would result in a
physically lighter and more comfortable AR eyewear solution as well. We
are still early into 5G development
and adoption, but it should be noted
that implementing this hypothetical
5G infrastructure would likely not be
cheap. Most companies currently utilizing private 5G networks are large
manufacturers that need fast and reliable data from robots and sensors.
They also have deep pockets and robust technical support.
■ Back-End Content Supply Chain.
Hand-in-glove with the enhanced
transmission protocol, the ultra-efficient H.265 video codec continues
to be adopted into VR delivery platforms. This codec is the successor
to the ubiquitous H.264 codec and
improves upon the previous compression method to allow for twice the
resolution to be stored in the same
amount of data, or inversely, the same
resolution stored in half the amount
of data. These two advancements
alone will see the quality of users' VR/
AR experiences leap forward without
much additional investment from producers or consumers.
■ Visuals & Display Resolution. The
visual delivery of content through advancements in high-fidelity displays
has been catching up as well. As one
might guess, a critical factor in convincing the brain of new realities is
the ability to present it with life-like
imagery that mirrors actual reality.
For VR and AR alike, this has proven
to be the challenge that stymied both
industries.
■ Foveated Rendering. Recently, VR
headset displays have a few notable
champions in the race toward "retina-
