Oculus Rift, a virtual reality headset, is not the first attempt to create a device enabling people shift into another reality. Various helmets with monitors were developed in the last century, since the beginning of the1990s, but the developers have always faced two main problems. They are the price of such device and a comfort of use. Oculus Rift plans to solve the issue of unaffordable prices, offering the device at a relatively low price. But what concerns the comfort of using a virtual reality helmet and related problems – a lot of unanswered questions still remain here.
One of the major inconveniences of a virtual reality immersion is the so-called “motion sickness”. It occurs when a man in a helmet observes changes in the environment but do not really feel them because the visible image motion is not supported by the sensations of the human body. That results in the feelings of nausea and vertigo or something like sea sickness. A popular belief that only frail people with weak vestibular system may experience the discomfort is not true. Tests show that quite healthy people may demonstrate the aforementioned sympthoms too. Oculus Rift developers pay much attention to this problem, namely they try to increase a screen resolution and install additional body and head movements trackers. Most of these functions will appear in Oculus Rift HD version.
A significant part of potential buyers who wear glasses and suffer from different vision disorders is deeply concerned with the possibility of using Oculus Rift. Developers report they were well aware of this problem and removed it in advance. Two methods were created and both seem rather successful. The first one is a binocular adjustment meaning you can adjust a distance from the eyes to the screen. The second solution is special optical inserts or internal glasses. Although developers warn that serious eye diseases like astigmatism can be solved only with the help of special programs.
Many people are familiar with eye fatigue emerging after a prolonged sitting in front of the computer monitor. There are fears that eyes will get tired in Oculus even more. But the developers claim the eyes won’t get tired more, but on the contrary, less. The fact is our eyes require a different focus. In a real life we are constantly changing the vision focus from objects in front of us to remote objects and vice versa. While sitting in front of the monitor, the focal distance is constant and that harms eye muscles and causes eye fatigue. Oculus Rift will make our eyes change focus in a way it happens in reality. Currently there special programs for Oculus Rift are developed, allowing to correct strabismus, for instance.
