Quick Tip: Vestibular Disorders
Animating or moving content may cause nausea or dizziness in some people. Vestibular Disorders are caused by parts of the inner ear and brain that process the sensory information involved with controlling balance and eye movements. The following can result in difficulties for users with vestibular disorders:
- High contrast graphics with tight parallel lines.
- Animated scrolling that lasts longer than perhaps 1/4 second.
- Parallax or reverse parallax – simultaneous foreground and background scrolling in different directions or at different speeds.
- Moving images beneath static text.
