When we see or hear a reference to advanced technologies, many of us think of modern machinery used to perform physical processes, often without human intervention.  CNC machining centers, robotic work cells, automated logistics systems, drones, and autonomous vehicles often eclipse other technologies in our visions.  Digital tools are often overlooked simply because many of us find it difficult to visualize their use in the physical environments we regularly inhabit.
     There is an entire class of digital tools that is rising in prominence, yet currently receives little attention in mainstream discourse:  augmented reality (AR).  There are valid applications of AR in varied industries.  Increased awareness and understanding of these applications and the potential they possess for improving safety, quality, and productivity will help organizations identify opportunities to take the next step in digital transformation, building on predecessor technologies such as digital twins and virtual reality.

     The use of digital technologies in commercial applications is continually expanding.  Improvements in virtual reality (VR) systems have increased the practical range of opportunities for their use across varied industries.
     As discussed with respect to other technologies experiencing accelerated development and expansion, several definitions of “virtual reality” may be encountered.  Researchers and practitioners may disagree on which applications qualify for use of the term.  For our purposes, we will use a simple description of virtual reality:
“Virtual reality” is an experience created, using a digital twin or other model, where

• the user has a first-person perspective (i.e. immersion),
  
• sensory input is limited to the “reality” created (i.e. sensory deprivation and replacement),
• physical phenomena are added to enhance realism (e.g. motion, acceleration, heat), and
• the user can interact with the simulated environment.
