“…Aside from habituation, a growing number of visual-based and interaction-based (primarily software-based) techniques are being generated to address VIMS in VR [2,22,26,27,70]. One of the most promising of these techniques for addressing VIMS is the use of visual rest frames.…”

Visually Induced Motion Sickness (VIMS) plagues a significant number of individuals who utilize Virtual Reality (VR) systems. Although several solutions have been proposed that aim to reduce the onset of VIMS, a reliable approach for moderating it within VR experiences has not yet been established. Here, we set the initial stage to explore the use of controlled olfactory stimuli towards reducing symptoms associated with VIMS. In this experimental study, participants perceived different olfactory stimuli while experiencing a first-person-view rollercoaster simulation using a VR Head-Mounted Display (HMD). The onsets of VIMS symptoms were analyzed using both the Simulator Sickness Questionnaire (SSQ) and the Fast Motion Sickness Scale (FMS). Notable reductions in overall SSQ and FMS scores suggest that providing a peppermint aroma reduces the severity of VIMS symptoms experienced in VR. Additional anecdotal feedback and potential future studies on using controlled olfactory stimuli to minimize the occurrence of VIMS symptoms are also discussed.

“…Disorientation increases significantly when the viewpoint os changed abruptly by teleporting the user to new locations in virtual environments [15]. Gaze directed pointing techniques are advantageous, and a viewpoint snapping technique has been proposed [16] to eliminate intermediate frames, making the rotation discrete and more realistic. The snapping technique eliminates viewpoint changes up to 22.5°, making it more comfortable for users.…”

Human eyeballs move relative to the head, resulting in optimal changes in the viewpoint. We tested similar vestibular ocular reflex (VOR)-based movement on Zenmuse-X3 gimbal camera relative to pre-defined YAW movements of the DJI Matrice-100 unmanned aerial vehicle (UAV). Changes in viewpoint have various consequences for visual and graphical rendering. Therefore, this study investigated how to minimize these changes. OpenGL visualization was performed to simulate and measure viewpoint changes using the proposed VOR-based eyeball movement algorithm and compared with results of VOR based gimbal movement. The gimbal camera was setup to render images (scenes) on flat monitors. Positions of pre-fixed targets in the images were used to measure the viewpoint changes. The proposed approach could successfully control and significantly reduce the viewpoint changes and stabilize the image to improve visual tracking of targets on flat monitors. The proposed method can also be used to render real-time camera feed to a head-mounted display (HMD) in an ergonomically pleasing way.

“…However, since the viewpoint is coupled to the selection ray, this can yield excessive head motion which in turn can cause neck fatigue, and disorient users. Worse, the excessive head movement of the user may induce nausea and cybersickness [12]. To avoid these problems, most modern head-mounted displays (e.g., the Oculus Rift, and HTC Vive) employ tracked wand input devices.…”

We present an evaluation of a new selection technique for virtual reality (VR) systems presented on head-mounted displays. The technique, dubbed EZCursorVR, presents a 2D cursor that moves in a head-fixed plane, simulating a 2D desktop-like cursor for VR. The cursor can be controlled by any 2 degree of freedom (DOF) and 3/6DOF input device. We conducted two experiments based on ISO 9241-9. In the first study, we compared the effectiveness of EZCursorVR using six different controllers. Results indicate that the mouse offered the best performance, while the position-control joystick performed the worst. In the second study we evaluate EZCursorVR using three different transfer functions using the mouse with different degrees of cursor acceleration. Results indicate that, despite previous research, constant acceleration performed better than the other two transfer functions. We believe that future evaluation needs to be conducted to evaluate different acceleration curve steepnesses using the same transfer function.iii Acknowledgements First and foremost, I would like to thank my thesis supervisor, Dr. Robert Teather for his continuous guidance and support throughout my time as a graduate student. I am grateful to him for not only teaching me how to be a better researcher, but also for pushing me to publish my work in academic conferences. His perseverance in ensuring that my research wasn't just confined to Carleton University, led to several publications and gave me the opportunity to present my work internationally in Denver, CO and Brighton, UK.
