Smart Friday with RobotLAB - Optical illusions

Optical Illusions

Check out this amazing experiment that NAO robot will show to you and try to figure out why this happens! 

What is an Optical Illusion?

Optical Illusions use color, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality, does not match the true image. Perception refers to the interpretation of what we take in through our eyes. Optical illusions occur because our brain is trying to interpret what we see to make sense of the world around us. Optical illusions simply trick our brains into seeing things that may or may not be real.

Refraction of Light-Simple Water Experiment!

Why? 

 

Have you noticed that things look a little funny when you see them through a glass of water? Some of the aberrations are caused by the imperfection in the glass production. But there is more to it.

Refraction is the bending of light as it passes from one transparent medium into another. This bending by refraction allows us to make use of lenses, magnifying glasses, prisms, etc.

It also makes it possible for us to see because our eyes use lenses to focus images onto our retina.

Refraction Experiment - bending of light

 

When light travels through a cylindrical glass, it bends it enters the glass and water, and then it bends again when leaving the water and glass.

As a result, the light paths cross and the image appears to be flipped horizontally (left/right).

Open Question Question-mark-hi

How can a robot know to differentiate an illusion to a real information? We human if we see something through water we know it, how would NAO know it? (submit your answer in the comments)
