While the Nintendo Wii was a technological breakthrough, the other major advancements in the field of VR have occurred without the aid of video games. Virtually every home is equipped with a television set that is capable of displaying an image on a monitor that can be viewed through a pair of glasses.
are commonly referred to as a viewer. More recently, the term has been expanded to refer to any device that transforms an image or video, either recorded or live, into a form that can be viewed through eyeglasses.
These viewers vary in size, shape, and price, but the most popular ones are tiny like a Blu-ray player or similar computer devices. Even this is beginning to change.
The variety of technology available is not limited to a single type of viewer. Some of the newer types include a screen or screens mounted on the viewer. The lenses can contain more than one color or two different colors.
Also called a FOV, or field of view, the technology allows an additional two-dimensional image to be viewed by using either one or two lenses in tandem. The main advantage of the VHS lens is that it can show a view of the object or an object that is up close, but is also extremely narrow.
This is helpful for the viewer’s field of vision, which can narrow considerably when the viewer is further away from the object. Another added benefit is that it is possible to use a camera to zoom in and out on objects.
which uses a controller for touch input, just like a mouse or an actual keyboard. With a Leap Motion or similar controller, a user can effectively “feel” a virtual object or character.
A headset that includes a motion-sensor technology, rather than just a viewer, is another advance in the realm of virtual reality. It allows the wearer to see movement, much like a 2D television would, but without the hassle of wires.
There are two common types of sensors used for this technology. These are the eye-tracking and the hand-tracking systems.
The eye-tracking system simply uses light sensors to provide the data about the depth of an object. While this provides a large improvement in the overall ability of the headset to provide the viewer with a real-time display, it is fairly inaccurate at times.
The hand-tracking system uses computer processors to help the headset determine the movements of the hands. This is a better solution for many users, as it offers better accuracy.
