The Various Types of Virtual Reality Systems Ever since virtual reality started to make headlines in the tech gizmo magazines, more and more people have started to take an active interest in what it can do for them. Numerous industries and fields nowadays make use of virtual reality to ease their operations and enhance the quality of their services and products. Many leading manufacturers of electronic gadgets and devices are nowadays coming up with their own versions of virtual reality headsets that offer similar features. While each of these devices comes with their unique features, there are certain things that always remain common among these products. Here are some of the things that you need to look for when you are getting virtual reality systems.
Virtual reality headsets fit on the head of a user and operate much like a visor or a sunglass. They either consist of a single small display lens or two lenses for both eyes. The lenses are going to create a 3D image of the environment or the objects in order to create the illusion of a complete environment.
The head mounted display of a VR headset may come with or without a tracking system. If the display does not have a tracking system, then a person using the headset is going to see the same interface no matter in which direction he or she is moving his/her head.
When the display comes with a tracking system, it can note the position and angle of the head of the user and accordingly adjust the image. Specialized eye tracking methods are used to detect where a user is directing his/her attention. Such input is used to bring those specific areas into better focus.
Some VR headsets make use of an optical see-through display where a real world image is overlaid by a CGI impression.
