your eyes back to the screen to read destroys the illusion we are trying to create.
1. Sit normal distance from your computer screen.
2. Place your index finger directly on the black bar between the two images.
3. Keeping your eyes focused on the tip of your finger (not the screen), slowly move your
finger towards your eyes.
4. Keep your eyes focused on your finger tip but use your peripheral vision to notice
whats on the screen. Move your finger forward and backward until you see three (and
only three) full images on the screen behind your finger. For this example, you will see
three blue circles. They will be out of focus but you can clearly tell when there are three
instead of four. Take your time and you'll find the exact distance.
5. Here is the tough step: Slowly allow your focus to switch from your finger tip to the
center image. Hopefully, it will be a 3-d image that evokes the 'wow' response.
You might have to try this several times. If the illusion falls apart, go back to the
beginning and try again. You must override what your eyes and brain have learned
about focus and distance.
You might find that you are starting to see the three dimensional image but as the image
comes into sharp focus you loose the effect. This is a good sign, it means you are close
to seeing in 3-d. You must fool your mind, stay in the 'zone' and not allow your eyes to
try to focus directly onto the screen. Try to keep them focused instead on the 'imaginary'
3-d image that is the middle of the three images you see.
When you are 'in' you will see the center image popping in all its 3-d glory. There will
also be two 'ghost' images on either side of the sharp 3-d image in the middle. In the
practice example above, you should see a blue circle that appears to hover over a green
'x' that is hovering above the red grid.
The 3-d images on this web site utilize the 'cross-eyed' method. This means that your
right eye will be looking at the image on the left and your left eye will be looking at the
image on the right.
For some people the adjustment is quick. Some people need a lot of practice.
Unfortunately, some people never seem to get there at all.
Still can't make it work? Try this.
