To not seasick, virtual reality need a nose Bashny.Net

Nose drawing saves from kinetosis


In the fifties of the last century in the US Navy was created simulator for training pilots of helicopters. Users are invited to break away from the surface to make a flight and landing. And all this without having to fly in fact it meant less risk to human life. But for some reason, a large proportion of pilots experienced nausea during virtual flights. It was like a normal seasickness or motion sickness, symptoms include dizziness, nausea, sweating, loss of orientation.

This is probably the first manifestation of the disease in the history of the simulation. Half a century later, nothing has changed, and unambiguous counter found. A huge number of new owners of virtual reality glasses Oculus Rift experience exactly the same symptoms on the official forum of discussion has , and the problem of признаёт and the manufacturer. Members offer a variety of solutions, there is even a рекомендации drinking a few beers before wear a helmet. Researchers at Purdue University have found a simple way to ease the effects of the disease simulation: they offer draws nose.

Feeling responsible for several systems of perception: it common touch and a sense of body position or somatosensory system, fluid-filled tube in the ear - the vestibular apparatus, finally, it oculomotor apparatus, the muscles that control eye movement. As David explains Uittinghill, assistant professor of computer graphics technology at Purdue University, body movements do not coincide with what is happening in the field of view of the eye, and it is not to the liking of our brain. If the eyes do not see movement, and the body moves, we can rock; if the vestibular apparatus is confident that the body motionless, his eyes say to the contrary, the same process.

To combat the disease simulation was used the fact that in the presence of fixed objects in the field of human kinetosis effects become weaker. These objects can be car dashboard, or virtual cockpit nose. Last far more versatile and suitable for almost any videogame. The idea to insert in the center of a virtual nose belongs to the student Bradley Ziegler.

Studies have indeed confirmed that nasum virtualis reduces the effect of the disease simulation. In tests participated 41 test, they performed actions of varying intensity in different applications using a virtual reality helmet. For example, some have studied the interiors of the mansion, others rode on the "roller coaster". Some users have played with a virtual nose, the other without it. Surprisingly, while the subjects did not notice the nose. Almost all much astonished when, after the experiments they were told about the object in the field of virtual reality helmet.

The analysis showed that the average house with a nose studied without symptoms kinetosis 94, 2 seconds longer, and the attraction nose helped to drive without disease simulation for 2, 2 seconds longer. This is explained by the fact that the demo with a trip to the trolley much more intense, so it starts to rock faster. She also just shorter. Uittinghill says that two-second increase was confident enough. The study of the mansion is not as intense, but over time the signs of seasickness begin to appear and there, and these 94 seconds - a great achievement.

Researchers relied not only on the sensations themselves subjects was measured as electrical conductivity of the skin to determine the level of perspiration - Side indicator of disease simulation. Differences have also shown the superiority of virtual reality with the nose.

Investigation continues. Uittinghill said the goal is to develop a fully predictive model that will predict on the basis of individual data the expected level of sickness for everyone. There are also questions about the color of the skin of the virtual nose, its position and size. Answers may be important for the future of helmets by type Oculus Rift: as говорит John Carmack himself, people like to show points, they buy a set, try it at home, then starts vomiting. And if the product is released to anyone not like it, then virtual reality will quickly lose its appeal and will again become uninteresting failure native nineties .
