“…One commonly reported side-effect of HMDs is that they are nausegenic [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The motion sickness experienced with HMDs is most appropriately referred to as 'cybersickness' [11,23].…”

Cybersickness is often experienced when viewing virtual environments through head-mounted displays (HMDs). This study examined whether vection (i.e., illusory self-motion) and mismatches between perceived and physical head motions contribute to such adverse experiences. Observers made oscillatory yaw head rotations while viewing stereoscopic optic flow through an Oculus Rift HMD. Vection and cybersickness were measured under 3 conditions of visual compensation for physical head movements: "compensated", "uncompensated", and "inversely compensated". When a nearer aperture was simulated by the HMD, vection was found to be strongest in the "compensated" condition and weakest in the "inversely compensated" condition. However, vection was similar for all 3 conditions during full-field exposures. Cybersickness was most severe for the "inversely compensated" condition, but was not different for the other two conditions. We conclude that mismatches between perceived and physical head-movements can contribute strongly to cybersickness. The relationship between vection and cybersickness is weaker and appears complex.

“…Such immersive virtual environments can generate cybersickness (a constellation of motion-sickness like symptoms) in many participants. 4,5 Common symptoms of cybersickness include nausea, vomiting, headache, somnolence, loss of balance, and altered eye-hand coordination. These are obviously undesirable events, particularly in participants with impaired function in the CNS.…”

In this paper, the current "state of the art" for virtual reality (VR) applications in the field of motor rehabilitation is reviewed. The paper begins with a brief overview of available equipment options. Next, a discussion of the scientific rationale for use of VR in motor rehabilitation is provided. Finally, the major portion of the paper describes the various VR systems that have been developed for use with patients, and the results of clinical studies reported to date in the literature. Areas covered include stroke rehabilitation (upper and lower extremity training, spatial and perceptual-motor training), acquired brain injury, Parkinson's disease, orthopedic rehabilitation, balance training, wheelchair mobility and functional activities of daily living training, and the newly developing field of telerehabilitation. Four major findings emerge from these studies: (1) people with disabilities appear capable of motor learning within virtual environments; (2) movements learned by people with disabilities in VR transfer to real world equivalent motor tasks in most cases, and in some cases even generalize to other untrained tasks; (3) in the few studies (n = 5) that have compared motor learning in real versus virtual environments, some advantage for VR training has been found in all cases; and (4) no occurrences of cybersickness in impaired populations have been reported to date in experiments where VR has been used to train motor abilities.

“…This suggests that the orientation to the virtual world provided inaccurate reference information when compared to the visual reference. 66 While some researchers have suggested the use of an independent visual reference connected to an inertial reference within the virtual environment, this research is not yet conclusive and more study is needed to determine if this technique has merit. 67 Evidence that negative affects of simulators are more postural and physiological than cognitive suggests that virtual environments have excellent potential for training and orientation, once simulator and virtual environment design has resolved the current issues of refresh rate, display lag, and orientation with the inertial frame of reference.…”

JCC(X)-2000-008112. DISTRIBUTION/AVAILABILITY STATEMENT Approved for public release, distribution unlimited SUPPLEMENTARY NOTESThe original document contains color images. ABSTRACTThe JCC(X) is being designed to be a command and control ship that will house command staff who will plan and execute levels of conflict ranging from Operations Other than War through Major Regional Conflicts. The command staff will be composed of military and civilian personnel from the armed services of the United States and its allies, as well as personnel from other international agencies and organizations. In terms of human factors, the critical issue is that these key individuals will be exposed to stressors, such as motion sickness, that could cause degradations of cognitive or physical performance or both, with a potentially damaging effect on the success of the mission. This report consists of a Literature Survey of research conducted on the impact of ship motions on the cognitive and physical performance of humans. SUBJECT TERMS Human Factors Ship Motions Naval Engineering Motion Sickness PREFACE Ship Motion Effects and the JCC(X)The problems of ship motion on personnel can have a profound effect on the operational effectiveness of any given mission. Perhaps the most obvious of these effects, namely motion sickness, has been documented throughout history. Motion sickness is not a disease, nor is it a sign of physical or mental weakness. Many bold and courageous people have suffered greatly from this condition, such as:• Julius Caesar;• The Spanish Conquistadors and the Portuguese mariners who sailed around the world; • Lawrence of Arabia suffered from "camel sickness"; • Lord Nelson, and many of his admirals, suffered from chronic seasickness even on his last voyage;• Charles Darwin, the famous naturalist, hated the sea because of severe and chronic seasickness; • Houdini, the famous escape artist, could not escape seasickness; and • Seasickness severely hampered efficiency during D-Day landings.Recently, scientific investigation into this issue has been undertaken, in addition to the anecdotal information from the experiences of sailors. It is essential that motion sickness and the potential solutions be addressed t...
