10 Questions
What is depth perception?
The ability to see things in three dimensions including length, width, and depth
What are depth cues?
Sources of information from within our body or from the environment that help us perceive how far away objects are
What is stereoscopic vision?
The brain's ability to put together two 2D images to extrapolate depth
Why do our eyes produce slightly different images on each retina?
Because our eyes are separated on our face
How do we translate 2D information into 3D?
By interpreting visual cues that indicate how near or far away objects are
What are primary depth cues and where do they originate from?
Primary depth cues are internal sources of information within our body that help us perceive how far away objects are. They originate from within our body.
Explain how our brain is able to interpret depth from two 2D images on the retina.
Our brain's ability to put together two 2D images in such a way as to extrapolate depth is called stereoscopic vision. It interprets the slightly different images produced by each retina due to the separation of our eyes on our face.
How is depth perception defined and what does it involve?
Depth perception is the ability to see things in three dimensions, including length, width, and depth. It involves the interpretation of visual cues that indicate how near or far away objects are.
Why do our eyes, despite producing two-dimensional images on the retina, provide us with the perception of a three-dimensional world?
Our brains have the ability to extrapolate depth from the two 2D images through the process of stereoscopic vision, despite the images displayed on the retina being 2D.
What role do external secondary depth cues play in depth perception?
External secondary depth cues are sources of information from the environment that help us perceive how far away objects are and therefore to perceive depth.
