Depth Perception

Depth Perception is the ability to perceive the world in three dimensions and to be able to perceive depth and distance of an object. Depth Perception consists of many monocular cues such as relative size, relative clarity, and many more. In this picture we are able to see the depth of the picture due to our depth perception.

Reversible Figures

Reversible figures are ambiguous 2D drawings that can be seen as 3D drawings and can be seen as two different pictures, this creates two different perspectives. In this picture two different images can be seen, one is a picture of Wolverine and the other one is of two Batman faces, this shows a 3D images which is depicted as the Wolverine face and there is a 2D image which is the Batman faces

Phi phenomenon

Phi phenomenon is when two lights that are next to each other create the illusion of movement.  If they blink on and off in quick succession, it looks like a single light that is moving between the two lights.  For example: the wheels and horse christmas lights aren't moving, they just look like it because the lights create the illusion of movement.

Binocular Cue : Convergence

 
Convergence is when your eyes must move slightly inward or converge. They do this so that people are able to determine if objects are close to them or far away. An example is when people move a pencil close to their face and look at it with both their eyes. Through this little experiment they are able to determine whether the object is close or far from them.

Stroboscopic movement

Stroboscopic movement is where the brain perceives movement as a rapid series of varying images.  This creates the illusion that the object is moving, but the motion we see is actually made in our heads.  In the picture, the person looks like they're moving their arms, when in reality, there are just many pictures of a human being put together to make it seem like their arms are moving.

Biinocular Cue : Retinal Disparity

Retinal Disparity is the difference in images that the two eyes see due the the different angles that the eyes see the world. In this picture it shows how two different images are received by each of they eyes. This shows how retinal disparity works due to the angle the eyes see.

Monocular Cues : Linear Perspective

Linear perspective is when a set of parallel lines go for a long distance and seem to converge into one single line. A good example of this is a railroad track, if looked at from a certain angle the tracks seem to become one at a certain point.
