Sickness or syndrome

In this book, we refer to any unintended, uncomfortable side effects of using a VR system as a form of VR sickness. This might include many symptoms that are not ordinarily associated with sickness, such as fatigue. A more accurate phrase might therefore be VR maladaptation syndrome, in which maladaptation refers to being more harmful than helpful, and syndrome refers to a group of symptoms that consistently occur together in association with the activity.
