I have learnt what optical illusion is about.
2. Outline THREE things you know about optical technologies.
-
An optical illusion is characterized by visually perceived images that differ from objective reality.
-
The information gathered by the eye is processed and the brain to give a percept that does not tally with a physical measurement of the stimulus source.
-
There are three main types of illusion – literal optical illusions that create images that are different from the objects that make them, physiological illusions that are the effects on the eyes and brain of excessive stimulation of a specific type – brightness, tilt, color, movement, and cognitive illusions where the eye and brain make unconscious inferences.
3. Identify ONE aspect of the project you feel uncomfortable about and really need to know. Explain the BEST way this could be resolved.
