The modern era of VR was brought about by advances in display, sensing, and computing technology from the smartphone industry. From Palmer Luckey's 2012 Oculus Rift design to simply building a case for smart phones [121,239,306], the world has quickly changed as VR headsets are mass produced and placed into the hands of a wide variety of people. This trend is similar in many ways to the home computer and web browser revolutions; as more people have access to the technology, the set of things they do with it substantially broadens.
This section gives you a quick overview of what people are doing with VR today, and provides a starting point for searching for similar experiences on the Internet. Here, we can only describe the experiences in words and pictures, which is a long way from the appreciation gained by experiencing them yourself. This printed medium (a book) is woefully inadequate for fully conveying the medium of VR. Perhaps this is how it was in the 1890s to explain in a newspaper what a movie theater was like! If possible, it is strongly recommended that you try many VR experiences yourself to form first-hand opinions and spark your imagination to do something better.
