What do I want out of this class

Without much awareness, we have been living in a world enriched by virtual reality. In this era of Big Data, whatever information, entertainment, and service that we desire can easily be accessed from the Internet via a handy smartphone. If we wish, we can actually live isolated without losing contact with the outside world. Self-learning is feasible with support of a wide variety of online study packages. Home-office is practicable with back-up of availability of information exchange. Food and life accessories are attainable via on-line shopping, while health and security can be assured by on-line professional service providers.

Even for reality interaction, simulation programs allow situation-simulated training attainable.  People no longer need to go on-site for military, space or flight practice. There are virtual-reality apps to help. The application can even free potential fashion buyers the burden of trying-on clothes. Co-operation in multiplayer networked gaming is also achievable without geographical limits. As for relationship building and maintenance, there are on-line social networking sites like Facebook and Instagram to help. Social interaction is extended beyond face-to-face communication but with possible real-time responses territory-wide. We can keep up friendship in a virtual world.

It is marvelous that virtuality and reality can blend together to provide such an enriched life to us. Of course, things cannot be 100% perfect. I believe there would be unintended bad consequences. Say, many people are addicted to the virtual social world and make the smartphone the thing next to their life. Still, it would be educational to know about the underlying secrets of the development and success of a virtual-reality.
