Cue conflict

A cue conflict is a state of brain discomfort where different visual cues and/or vestibular cues provide conflicting information.

In virtual reality (VR) near-eye displays, cue conflicts refer to discrepancies between the visual cues presented by the VR headset and other sensory cues, such as proprioceptive (body position) and vestibular (balance and motion) cues. VR systems strive to create immersive experiences by providing convincing visual simulations of virtual environments. However, discrepancies between visual cues and other sensory cues can lead to discomfort, disorientation, or even motion sickness.

VR near-eye displays

• Vergence-accommodation conflict

• Motion Parallax and vestibular conflict: In VR, users can move their heads to explore virtual environments, creating motion parallax cues that contribute to depth perception. However, if the virtual environment moves differently from the user's physical movement (e.g., acceleration, deceleration, or rotation), it can create a conflict between the visual cues and vestibular cues from the inner ear, leading to motion sickness or disorientation.
