“…However, the extent of physical movement possible in VR systems varies considerably depending on the set up-in some VR systems, the user may have freely tracked movement, whereas in others, that movement may be more restricted. Findings from Suma et al (2009) appear to contradict the implied prediction from this, where higher sickness was found in a "natural" walking condition compared with gaze-directed simulated walking-in other words, the condition with the larger vestibular input, which would be expected to have a lower level of conflict, elicited a higher level of symptoms.…”

“…Although this could strongly depend on the extent of technological development, real walking has been reported as a navigation technique that is prone to increasing cybersickness [ 52 ]. Thus, it is not clear to what extent each of the techniques, real walking and EHBD, contributes to increasing cybersickness.…”

Inertial sensors offer the potential for integration into wireless virtual reality systems that allow the users to walk freely through virtual environments. However, owing to drift errors, inertial sensors cannot accurately estimate head and body orientations in the long run, and when walking indoors, this error cannot be corrected by magnetometers, due to the magnetic field distortion created by ferromagnetic materials present in buildings. This paper proposes a technique, called EHBD (Equalization of Head and Body Directions), to address this problem using two head- and shoulder-located magnetometers. Due to their proximity, their distortions are assumed to be similar and the magnetometer measurements are used to detect when the user is looking straight forward. Then, the system corrects the discrepancies between the estimated directions of the head and the shoulder, which are provided by gyroscopes and consequently are affected by drift errors. An experiment is conducted to evaluate the performance of this technique in two tasks (navigation and navigation plus exploration) and using two different locomotion techniques: (1) gaze-directed mode (GD) in which the walking direction is forced to be the same as the head direction, and (2) decoupled direction mode (DD) in which the walking direction can be different from the viewing direction. The obtained results show that both locomotion modes show similar matching of the target path during the navigation task, while DD’s path matches the target path more closely than GD in the navigation plus exploration task. These results validate the EHBD technique especially when allowing different walking and viewing directions in the navigation plus exploration tasks, as expected. While the proposed method does not reach the accuracy of optical tracking (ideal case), it is an acceptable and satisfactory solution for users and is much more compact, portable and economical.

“…A study found that during the task requiring a navigationally complex environment and for a long period of time, it is preferable to use simulated walking [117]. On the other hand, another study reported that natural walking caused less MS than simulated walking in one out of two experiments involving a virtual maze [118].…”

In this paper, we present a review of the major issue of Virtual Reality -Cyber Sickness. As Virtual Reality becomes more and more popular and advanced technology, it is being used in a variety of areas, such as military, surgery, schools, etc. for training and education. Although at this point, Virtual Reality technology has multiple problems to overcome, Cyber Sickness issue is one of the most difficult ones, as it is closely linked to our physiology and Virtual Reality technology as well. Cyber Sickness symptoms are very similar to those of Motion Sickness, but are caused by Virtual Reality Environments. Due to its potential harm to human health, it is important to know the causes of this issue and possible ways to combat it. In this paper, we will highlight what aspects of Virtual Reality technology cause these symptoms and their outcomes.
