Motion sickness in VR (or VR sickness) occurs when there is a mismatch between your visual receptors and your vestibular system. In short, your eyes are telling your brain that you’re moving but your body feedback is stationary. This mismatch can be caused by two main things — the frame rate and latency of the headset and your locomotion within your virtual reality environment.
Frame Rates and Latency
Both the HTC Vive and the Oculus Rift have set 90 fps (frames per second) as the benchmark frame rate to match with the refresh rate of 90Hz of the headset display. At a lower frame rate, the image begins to drop out, and the stuttering of the image (known as judder) will start to make you feel sick.
Latency is the delay between head movement and the visual feedback in the headset. Our developers have made sure to optimize for low latency so that you remain comfortable while using the VR component of Inspace.
As mentioned earlier, VR sickness is caused by the mismatch between your ocular and vestibular systems. This is why the industry standard for moving around in VR is via teleportation.
When seeming to disappear and reappear in another spot your brain is not receiving any visual feedback that there has been a change in position because it's more similar to flicking through photos on a camera roll. We’ve made sure to adhere to these standards to make sure you and your clients have the most comfortable navigation while using virtual reality.
Note: avoid moving around for the person inside the VR headset. This mismatch for the user is worsened by the fact that they aren’t able to mentally prepare themselves for which direction they’re going next or when.
We understand not everyone is as comfortable jumping into VR, so our desktop mode allows spectators to watch the VR scene from a monitor, allowing you to still walk through the plans in real time and showcase the important details of the model.
Does Internet Speed Affect Quality?
Internet speed does not affect the performance of Inspace as the files are stored and read locally without the use of an internet connection. The only step that needs internet access is the licence check. As long as you’ve signed in and verified your account with the licence key, Inspace is ready to go.
If you're concerned with your VR quality, make sure to check that you’re plugged into a power source and that you’ve set your computer's power setting to the highest performance setting.
