The Effects of 0.2 Hz Varying Latency with 20-100 Ms Varying Amplitude on Simulator Sickness in a Helmet Mounted Display

Motion Sickness Side Effects and Aftereffects of Immersive Virtual Environments Created with Helmet- Mounted Visual Displays

We have investigated side effects and aftereffects evoked by moving the head to interact with a virtual environment (VE) shown in a helmet mounted visual display (HMD). The graphics computer of such a VE must monitor the HMD’s spatial orientation and position in order to present images from the proper perspective. Delays between head movements and image updating cause aberrant visual motion of ...

Characteristics of Head-Mounted Displays and Their Effects on Simulator Sickness

OBJECTIVE We examined the effects of several display characteristics of head-mounted displays (HMDs) on simulator sickness (SS). BACKGROUND Technological limitations, such as display delay and reduced field of view (FOV), affect perception when using an HMD and are often thought to be related to SS. Few studies have examined the relationship between FOV and geometric FOV (image scale factor) ...

Comparison in Degree of the Motion Sickness Induced by a 3-D Movie on an LCD and an HMD

Three-dimensional (3D) television sets are already on the market and are becoming increasingly popular among consumers. Watching stereoscopic 3D movies, though, can produce certain adverse affects such as asthenopia and motion sickness. Visually induced motion sickness (VIMS) is considered to be caused by an increase in visual-vestibular sensory conflict while viewing stereoscopic images. VIMS ...

Assessing Simulator Sickness in a See-through Hmd: Effects of Time Delay, Time on Task, and Task Complexity

Advances in helmet-mounted displays (HMDs) have permitted the design of “see-through” displays in which virtual imagery may be superimposed upon real visual environments. Such displays have numerous potential applications; however, their promise to improve human perception and performance in complex task environments is threatened by numerous technological challenges. Moreover, users of HMDs ma...
