"Motion Sickness" is similar to seasickness: what the eyes see does not match what the sense of balance perceives. As a reaction to the conflicting information for the brain, nausea and headaches can occur.
In virtual reality, motion sickness can be caused by the computer not calculating the position of the VR headset. In addition, the cause may be that the computer calculates the image shown in the VR glasses from the wrong angle or too slowly.
To avoid "motion sickness," consider the following steps:
The inaccurate calculation of the position can be improved quickly, according to experience. Make sure that you have installed a compatible version of SteamVR and make sure that your base stations can project the light patterns onto the glasses without too much occlusion. For example, ask meeting attendees who are standing in front of the base stations to step aside so they don't block the light patterns with their bodies.
For further instructions, please contact the manufacturer of your head-mounted display, e.g. HTC Vive (link: https://www.vive.com/de/support/vive-pro-hmd/category_howto/about-the-headset.html).
The Oculus Rift S does not need external base stations.
Halocline reduces the probability of motion sickness significantly by using abstract boxes instead of CAD models. However, if you have many objects in your virtual store floor and the image is calculated too slowly, please stop processing-intensive applications running in the background. Furthermore, you can divide your shopfloor into several work area and limit the content of each work area. To avoid performance problems, you should also use as few imported single objects from Halocline Assembly in a shopfloor as possible.
Blurred vision can also contribute to motion sickness. Therefore, carefully clean the VR glasses' lenses before each use. To avoid scratching the display, you can use a bellows to remove dust from the lens. Afterwards, you can wipe the lens with a cleaning cloth.
If you still see the image blurred through the VR glasses, this is usually related to the position of the device on your head.
With the following tips, you can adjust the visibility of the image on your VR glasses:
- Check that the VR glasses fit snugly on your head. Move your head with the VR headset. It will fit properly if the VR headset doesn't slip out of place.
- Make sure that you look through the lenses in the exact center to see the image sharply.
- Adjust the distance between the device and your eyes. Try different settings until you find the distance that works best for you.
Change the image resolution
You can set different image resolutions in the menu of the VR headsets. If an image seems stretched and blurry, select a smaller image size. This will make the image smaller, but also sharper.
Measure against motion sickness
If you feel uncomfortable in virtual reality, take off the headset and have a break.
In the case that the image suddenly does not match the movement of your head, a first measure can be to close your eyes for a short time.
