- 13. Perception loop from : researchgate
- 14. Perception loop from : researchgate Stimulus: external event that effects a sensorial system. The rule is : If we replicate the stimulus that you usually would get by the real natural environment and artificially create it properly then the human brain can’t distinguish between the real and the virtual stimulus.
- 15. VR effect on perception loop Conscioussness: VR changes the internal psychophysical state (consciousness) and make it accept something to be real. we can create emotions (positive/negative), sensations (fear…) and people cannot differentiate between the real fear and the artificial fear. (negative / positive) emotions, Proper artificial stimulus: try to produce a stimulus as close as the real one using different artefacts (Imagination). If the stimulus is badly recreated, it may lead to bad consequences such as cybersickness.
