One example of virtual reality that most of us often use without thinking about is our GPS navigation. Every time I hop into the car to go someplace, I pull out my phone and type in the destination. I quickly know which route will be the fastest, traffic conditions, road closures, or even if any cops are waiting to write a ticket ahead. This small virtual \”world\” created by someone is a massive help in our day-to-day lives. Everyone using the GPS app participates whether they know it or not, and all that data updates the virtual world in real-time. Different GPS applications have other overlays and interfaces. It never occurred to me that a designer had to imagine and portray pretty much the entire world for us to use and interact with their apps in a user-friendly and aesthetically pleasing way. I use Waze, but google and android have their versions of GPS that are each a little different in their way.
