New Stereo 3D Discovery: Women view Men 20% Larger Than Men View Themselves by:Sam Ramadan

Which also means that men view women 20% smaller than women do!

The scientific explanation for this, perhaps, has always been known, but it seems, this correlation was never before discovered, until Sam Ramadan was explaining to a small audience how humans perceive depth, and spontaneously mentioned the differences between how men and how women see each other, Sam noticed how some in the audience began giggling at one point, and how one member turned to another in the audience, and jokingly said "Yes Jim, be happy, your wife sees your "blank" much larger than you do", this concise true statement got a near-hysterical laughter response; gladly, Jim took it lightly and was not bothered. The response compelled Sam to share this new factoid with the rest of the world.

In this post, Sam explains the scientific reasoning, plus, how a person, using the Photo3D 303 Kit, can capture a stereo pair of 3D images representing his/her spouse's depth and size perception, then print the Stereo 3D image, put on the 3D glasses to experience first hand how his/her spouse sees.2d-vs-3d-depth-size-perception-1

Size perception in 2D visualization is based on perspective alone, which requires visual settings to support such visualization.

However in Stereo 3D visualization, size perception is a factor of both depth perception and perspective. Depth perception plays a very important role in recognizing and storing size information.

Depth perception is directly correlated to the stereo view angel, and in turn, the stereo view angle is proportionately related to the distance between the left and the right eye of a human being. The wider the eye separation, the larger the view angle and the smaller objects are perceived and vice-versa.

In laymen terms, a mouse sees humans as giants because the left-to-right eye distance separation of a mouse is very small. In the movie Monsters vs. Aliens, when Genormica (Suzan Murphy) got hit by a meteor, and grew into a 49 foot 11 inch tall woman, the city, in her eyes, became small and toy-like, this is because when she became a giant, Genormica's left-to-right eye distance separation grew proportionately and considerably. If Genormica grew but her left-to-right eye separation stayed the same, she would have continued to see the world as big as she used to see it but she would notice how her body became very big by comparison. When Dreamworks introduced a giant into the storyline of Monsters vs Aliens, they expanded their ability to show depth perception and allowed the audience to enjoy seeing the world in Genormica's eyes.

For men, the average left-to-right eye distance separation is about 6.5 cm, for women it is about 5.5 cm, so there is an average distance differential of nearly 20%. Children, have a smaller eye separation, on average, about 4.5 cm. In a private conversation, one of Sam's close friends was explaining to him how when he was 8 years old, he mistakenly walked into his father's bedroom when he was just coming out of the shower and happened to see his father's private organ, he thought wow that was pretty big, he further explained how this size perception experience stayed in his mind, and how as an adult, he could not help but wonder why his own organ is not as big as his dad's! Until Sam explained to him that he needed not to worry and that because he had a probable eye-separation of about 4.5 cm as a child, he perceived his father's organ to be about 45% larger than it really is, by comparison when seen now as an adult. When Sam finished, he could not help but notice his friend's sigh of relief.

Sam hopes that if this post can serve to relief some male-induced childhood complexes, then it would be worth writing.

At Mission3-D, the average eyes-separation is 6.61 cm for men and 5.70 for women, with Michael having the largest eyes-separation of 7.1 cm and Dianna the smallest at 5.3 cm, in this case Dianna actually views Michael about 30% larger than Michael sees himself. There will always be instances where a woman will have a wider eyes-separation than a man, but this is not the norm; at Mission3-D only Mayara had a larger eye separation of 6.2 cm than that of Bruce who had an eyes-separation of 6 cm.

To see for yourself how different you and your spouse sizes things, first using a ruler, note the separation distance between your own left and right eyes from center-to-center, then, mark distance X, do the same for your spouse and mark distance Y.

Then using the Photo3D 303 attachment:

First:

Place your digital camera on the attachment, best to place the attachment on a tripod as per the instruction manual, and capture three sets of images for, either you or your spouse, from 6 feet (2 meters) away: 1) for the right eye from zero placement and capture the first image, 2) then move the camera from zero to the distance separation of X and capture the second image, 3) now move the camera again to distance Y and capture the third image. Note for best results, use a camera with a 48 or 50 mm lens.

Second:

Mix images 1 and 2 using the Photo3D Mixer and save as your own visual perception, follow by mixing images 1 and 3 and save as your spouse's visual perception.

Third:

Print the resulting mixed images, at same life size, on your home Inkjet printer using glossy paper, put on your Photo3D glasses, and from the same distance and angle of where your camera was to the object, look at each image separately one right after another - don't look at them at the same time. To do it right, you need to look at one mixed image and remember it well, then look at the other mixed image right-a-way, then you will see that the mixed image which pair was taken from a shorter distance separation appears larger than that which was taken from a wider distance. You can now see how you and your spouse perceive the world differently.

This is a lot of fun to do, try it and if you do it right, it really works.
