How will augmented reality be useful in the workplace?

To simulate potential situations during training.

For clients to see how a room set up looks.

If I understand what you are asking, it's PROFITS!!!

This is something that I'm currently trying to develop for safety training purposes. Training individuals on hazard recognition without putting them in harm's way has traditionally been relegated to classrooms - which can be dry and many participants consider it a chore rather than something that benefits them. AR/VR applications can take this training, make it more interactive, and way more relevant to their specific workplaces as you can design instruction around the actual spaces they're in. The construction industry is already employing AR to a small degree - mostly in the planning and early building phases.

You can digitally share a room without sharing a room. You can view the same drawings and real experiences without being in the same place. Imagine and actual team standup while your team is across three different continents, but in the same room, face to face. Imagine a 0 cost way to decorate your office any way you want to. These are the ideas that keep me up at night...

Possibly good for training ! Situational

Safety

To show maybe an outcome of a job.

Augmented reality will forever change how virtual trainers and maintenance procedures are done for any hand on job. Visualization for autocad jobs and advertisement will be huge!
