Blind Spot Test

This station is designed to interest students in understanding our system of visual perception. The station also relates to the study of the brain, eye anatomy and cognitive/behavioral neuroscience, as it relates to vision. These exercises are intended to engage students in a discussion regarding careers that involve eye health (ophthalmology, optometry, opticians, physiatry and care of the blind) and research (neuroscience, physiology etc…). All students determine if they are color deficient (color blind) and use Aude Olivia Hybrid Images to see how our vision can be deceptive when viewing object or photos from a distance and close-up. Students also learn how to find their blind spots.

HYBRID IMAGES
Astro Diver
The image above may look like astronaut floating in the clouds. Taking a step back, or squinting your eyes, will reveal a diver floating undersea.
Disappearance at the Desk
The cluttered desk in the image above is constructed with high spatial frequency superimposition of color onto a black and white low spatial frequency field. At close distance, there is a woman sitting at her computer amidst a somewhat cluttered desk. These elements exist in pale colored tones. Once you move away from the image a few meters, the woman at the desk will disappear as well as the surrounding clutter. The pale colored tones will have faded into the sea of grayscale that exists on the lower spatial frequency plane.
Marylin Einstein
When you look at the image above, whose face do you see? At normal screen viewing distance you should see the face of the great scientist Albert Einstein. Now squint your eyes or take a few steps back grom the image. Does a certain Hollywood personality pop into view? The Marylin Einstein hybrid image was created by Dr. Aude Oliva for the March 31st 2007 issue of New Scientist magazine.
Dolphin Car
Right now you probably see a happy little dolphin splashing in some waves. Cleverly disguised within the low spatial frequency of this hybrid is nothing other than a car, which you will see once you step back a few meters.
Motorcycle Bicycle
This phenomenon of perceptual grouping will produce the most successful hybrids. Forms such as shadows, in this case, will work to the hybrids advantage. At close perceptual range, the parts of the motorcycle appear to belong to the shadow of the bicycle. Once the viewer steps back from the image, what appears to be cast shadows from the bicycle will regroup to to form a motorcycle. This grouping allows a seamless transformation from one object to another entirely different object.
Leopard Elephant
At a far distance, the leopard above will regroup with its ghosty halo to form an elephant. The prominent texture of the leopard spots transform into a dark shadowy region on the underbelly of the elephant, as if he recently exited a lake nearby.
