Summary
[edit]DescriptionBinocular rivalry2.jpg |
English: Normally, our left and right eyes see almost the same thing (as long as we have both eyes open of course). Our two eyes take in the same image, send this information to the brain, and the brain processes the information so that we can see the image. But we can also separate what the two eyes see and make them see different things, for example, by using special glasses. What do you think would happen if you saw a dog with your left eye and an ice cream with your right eye? You may think that we see a mixture of the two, i.e., half ice cream and half dog. Surprisingly, we do not. What we do see is the image of the ice cream and dog switching back and forth. This is called binocular rivalry because the two (“bi”) different inputs to the eyes (“ocular”) compete (or, “rival”) for dominance.
There are many ways to show two different images to the two eyes so that the left and right eyes see different things. Here, we use red-green glasses (also called anaglyph glasses). For this method, one needs to make one image green (here the dog) and one image red (here the ice cream) and mix those images. This you can see on the right hand side of the figure. If you then view this image through the glasses, the red transparent paper (here: left eye) filters the light so that the red image (the ice cream) cannot reach the left eye. The green transparent paper (here: right eye) filters the light so that the green image (the dog) cannot reach the right eye. This is why your left eye sees the dog and your right eye sees the ice cream. |
