what to do if Vision Pro causes discomfort or motion sickness
Apple has published several documents in which it talks about possible discomfort when using the Vision Pro headset and how to deal with it.
In case of visual discomfort (blurred images, double vision, dry/excessive eye moisture, sensitivity to light and eye pressure), you should stop using Vision Pro and wait for the condition to normalize.
To initially minimize visual discomfort, Apple advises adjusting the fit of the helmet so that the pressure is balanced across the nose and cheeks. To begin with, Vision Pro should be used for short periods of time, taking breaks every 20-30 minutes.
In a helmet, you should keep your head in a vertical position, preventing it from tilting in one direction or another. It is also advisable to sit in an upright position when watching 3D movies or spatial video.
Those who may experience motion sickness while using Vision Pro should also temporarily abandon it and reduce sessions. With motion sickness, dizziness, nausea, decreased attention, upset stomach, increased salivation, headache, fatigue, and sweating may occur. Apple says it may take up to 30 minutes for these symptoms to resolve.
Users were advised to reduce head and neck movements. Visual motion can be reduced by reducing window sizes, lowering the immersion level, and enabling the motion reduction setting in the Accessibility section of the settings.
In general, the headset should be used in a “controlled” environment or outdoors where there are no obstacles to trip over or hit with hands. Apple warns that doorknobs and cabinets can catch the power cord and cause it to disconnect. Vision Pro should not be used in extreme temperatures, rain, fog or any humidity as water damage is not covered by the warranty. It is better to wear the headset in a well-lit place.
Finally, the helmet battery should be stored in a ventilated area so that it does not heat up.
It was previously reported that Apple is studying how to make Vision Pro headsets more comfortable to wear and has already published a patent titled “Method and Apparatus for Multi-Level Pose Recognition.” It will allow the device to measure the tension of the neck muscles without special sensors.
