Writer: Emil Venere, 76, David Whittinghill, 76, Virtualis: A Simple Technique for Reducing Simulator Sicknessĭavid Matthew Whittinghill, Bradley Ziegler†, James Moore‡, and Tristan Case§ "Our long-term goal is to create a fully predictive model of simulator sickness that will allow us to predict, given a specific set of perceptual and individual inputs, what level of simulator sickness one can expect," Whittinghill said. "Our suspicion is that you have this stable object that your body is accustomed to tuning out, but it's still there and your sensory system knows it," he said. It isn't clear why the virtual nose evidently reduces simulator sickness. The measurements indicated EDA differences between subjects playing games with the nose and without. Researchers also used electro dermal activity (EDA) sensors to record electrical conduction across the skin, which is affected by sweating due to excitement, a proxy indication of simulator sickness. For the Tuscany demo it takes more time, but eventually you start getting queasy, and 94 seconds is a huge improvement." "We had a reliable increase of 2 seconds, and it was a very clear trend. "The roller coaster demo is short, but it's very intense at times, spinning upside down, jumping across chasms, plunging fully vertical, so people can't do it very long under the best of circumstances," Whittinghill said. "Surprisingly, subjects did not notice the nasum virtualis while they were playing the games, and they were incredulous when its presence was revealed to them later in debriefings," Whittinghill said.įindings showed the virtual nose allowed people using the Tuscany villa simulation to play an average of 94.2 seconds longer without feeling sick, while those playing the roller coaster game played an average of 2.2 seconds longer. They were not told that the nose was there. Some of the subjects played games containing the virtual nose, while others played standard versions. In another, it's the white-knuckle thrill ride of a roller coaster. In one of the applications, the user navigates the interior of a Tuscany villa. Also working on the research are undergraduates James Moore and Tristan Case.įorty-one test subjects operated a number of virtual reality applications of varying motion intensity while wearing a virtual reality headset. The researchers have discovered that the virtual nose, or "nasum virtualis," reduces simulator sickness when inserted into popular games.įindings were presented earlier this month during the Game Developers Conference in San Francisco. You tune it out, but it's still there, perhaps giving you a frame of reference to help ground you." "You are constantly seeing your own nose. "It was a stroke of genius," said Whittinghill, who teaches video game design. His research team was studying the problem when undergraduate student Bradley Ziegler suggested inserting the image of a virtual human nose in the center of the video display. "But you can't have a cockpit in every VR simulation," Whittinghill said. So if you see motion in your field of view you expect to be moving, and if you have motion in your eyes without motion in your vestibular system you get sick."Īnecdotal evidence has suggested simulator sickness is less intense when games contain fixed visual reference objects - such as a racecar's dashboard or an airplane's cockpit - located within the user's field of view.
"The problem is your perceptual system does not like it when the motion of your body and your visual system are out of synch. "Simulator sickness is very common," said David Whittinghill, an assistant professor in Purdue University's Department of Computer Graphics Technology. Various physiological systems govern the onset of simulator sickness: a person's overall sense of touch and position, or the somatosensory system liquid-filled tubes in the ear called the vestibular system and the oculumotor system, or muscles that control eye movements.
