Perception

• The information we receive through our senses is called sensation
• Perception is how we interpret or make sense of the sensory information that we receive
• Auditory perception - information related to hearing
• Tactile perception - information related to touch
• Visual perception - information related to sight
• Gustatory perception - information related to taste
• Olfactory perception - information related to smell
• Binocular depth cues - a way of detecting depth or distance, which requires two eyes in order to work
• Depth cues - a feature of an image which indicates distance
• Height in Plane - how high the object appears in the image
• Linear Perspective - when straight lines are angled so that they would come together at a point on the horizon
• Monocular depth cues - a way of detecting depth or distamce which will work with just one eye
• Relative size - how large an object appears in an image
• Occlusion - when one object seems to cover part of another object
• The 2 monocular depth cues are convergence and retinal disparity
• The 4 monocular depth cues are height in plane, occlusion, relative size and linear perspective
• Convergence - a form of depth perception which uses how eye muscles focus on images
• Retinal disparity - a form of depth perception which compares the images from 2 eyes, side by side
