At the end a basis for preliminary information required for creating virtual reality environments is formed from the cited sources. The most common source for sickness in virtual reality is when the user's self-image of movement (vection) doesn't match with the vestibular sensory output. This sensory conflict causes the motion sickness. VR-sickness can be prevented with design. Examples of effective design patterns include avoiding situations where the user cannot control the camera and creating fixed points in the environment for the user's eye to rest at. By understanding the problems and causes that lead to sickness, the duration and severity of sickness can be minimized.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-04-16T05:28:01Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-04-16T05:28:01Z (GMT).
