Because of binocular vision, it is possible to make stereopsis.

Binocular Cues Explainedīinocular cues pass information to our retinas and then our brain processes the information to turn it into what we see through our eyes.īinocular cues mainly include binocular convergence and retinal disparity, which work for exploiting vergence and parallax. And, in this way, it is possible to indicate the exact location of the visual attention of the viewer. In this case, a proper method is required for identifying the fixations. However, it is not possible to guess where the targeted object is paying the attention to without making further analysis. When this raw data becomes processed even to a little extent like Gaze Intersection Point (GIP), at that time, it can be referred to be informative. Most part of this raw eye movement data is meaningless unless your brain starts to process it. The primary goal or objective of eye movement analysis and measurement is to get an in-depth insight into the attentive behavior of the viewer.īefore your brain processes the information taken in by your two eyes, the information is called raw eye movement data. Hunters like Chuck Adams and Jedediah Strong Smith have always given a higher level of concentration on getting a deeper knowledge regarding the significance of binocular cues and distance discrimination in natural scenes. So, an in-depth quantitative assessment on those movements can provide you with core information related to the neural control strategy of your brain.įor this particular reason, a proper understanding of how vergence can be controlled in both symptomatic and normal human beings has always been one of the most critical goals of vision clinicians, scientists, and bioengineers. The vergence of eye movements mainly reflect the brain’s functions. Then, it steers the extraocular muscles for bringing those images into the appropriate register on your retinas. Whenever your targeted object makes a move in-depth, your brain can easily recognize the changes that occurred in the position of your retinal images.

Well, vergence or disjunctive eye movements mainly work for providing us with a single vision through the procedure of bringing the bifixation images onto the related and corresponding retinal points of our two eyes. When it is the discussion of the binocular cues, at that time, it is essential to make an in-depth discussion on the analysis of vergence. Actually, our brain processes the information taken in by our two eyes to convert the info into a three-dimensional interpretation. Generally speaking, if there were no binocular cues, then it wouldn’t have been possible for us to see the 3D world. And these cues have a deep connection with the sensory information of the three-dimensional (3D) world. Those depth cues are usually categorized into different types of binocular cues. The main reasons for the arousal of depth perception are varieties of depth cues. Depth perception plays a very important role in our visual system. For animals, the corresponding term to depth perception is called depth sensation. Well, depth perception is referred to the visual ability of the human being for perceiving the world in 3-dimensions (3D) along with the distance of a particular object. Then, our brain processes the captured information with a view to perceiving the distance or depth.īefore we make a jump into the detailed discussion regarding binocular cues, it is vital for us to know about depth perception. To put it simply, binocular cues are all the information that is taken or captured by our two eyes.
