“…An issue with the sighting test is that it assesses the preference of an eye in a monocular task, that is, it forces the subject to choose an eye, when in fact most everyday visual tasks, for example, reading, involve both eyes. What speaks for a superior performance of the sighting dominant eye is research that compared the function of dominant and non‐dominant eyes . A study of the effect of ocular dominance on latency and amplitude of visual evoked potentials found shorter latency as well as greater amplitude for the dominant eye .…”

“…What speaks for a superior performance of the sighting dominant eye is research that compared the function of dominant and non-dominant eyes. [17][18][19] A study of the effect of ocular dominance on latency and amplitude of visual evoked potentials found shorter latency as well as greater amplitude for the dominant eye. 20 Other studies have found poor agreement between the sighting dominant eye and performance superiority 14 and it has been suggested that the dominant eye has no unique role in vision other than in monocular tasks.…”

Background:It is well known that problems with binocular vision can cause issues for reading; less known is to what extent binocular vision improves reading performance. The purpose of this study was to explore the role of binocularity by directly comparing monocular and binocular reading in subjects with typical reading skills and normal binocular vision. A secondary purpose was to assess any asymmetry in monocular performance and its association with the sighting dominant eye. Methods: In a balanced repeated measures experiment, 18 subjects read paragraphs of text under monocular and binocular conditions. All subjects went through an optometric examination before inclusion. Reading speed and eye movements were recorded with an eye tracker. Results: The mean difference in reading speed (2.1 per cent) between monocular (dominant and non-dominant eye averaged) and binocular reading speed was not significant. A significant difference in reading speed was found between binocular and the non-dominant eye, as determined by the far sighting test (p = 0.03). Monocular reading showed significantly increased (8.9 per cent) fixation duration (p < 0.01) and longer regressive saccades by 0.43 character spaces (p < 0.01). Reading with the non-dominant eye, as determined by the near sighting test, showed increased progressive saccade length by 0.2 characters compared to the dominant eye (p = 0.03). No other significant differences between dominant and non-dominant eyes were found. The agreement between the faster reading eye and ocular dominance was 44 to 56 per cent depending on whether dominance was determined at near or far. Conclusion:The outcomes suggest that in subjects with normal binocular vision, there is no marked enhancement in reading performance by binocular vision when reading paragraphs of text. Furthermore, the monocular reading performance appears to be close to equal and any small differences in performance appear not to be strongly associated with ocular dominance.

“…Ocular dominance is defined as the eye used for sighting, and is not merely the result of superior measures of visual function, such as visual acuity and contrast sensitivity [9]. The perceptual dominance of the dominant eye is suggested by its functional dominance in conjugate eye movements, its priority in visual processing, and the activation of a larger area of the primary visual cortex compared to the non-dominant eye [22][23][24].…”

“…Dominant eye was regarded as the eye when closed caused more change [12].After finding the dominant eye of the test subject the eye tracker was calibrated to it. Performing the calibration on the dominant eye yields accurate result which is an important issue in this project [15,12,11]. The calibration time differed from one user to another.…”

Under natural viewing conditions humans tend to fixate on specific parts of images that interest them naturally. A saliency map is the map of regions which are more prominent than other regions in terms of low level image properties such as intensity, color, and orientation. With some modifications it can be used to simulate the natural human fixations also known as gaze. There are numerous applications in the field of engineering, marketing and art that can benefit from understanding the human visual fixation such as image quality evaluation, label design etc. The objective of this research is to understand the factors that influence the saliency map and gaze map and to modify the saliency map in order to make it similar to the gaze map. Eye movements of 20 test subjects were captured using eye tracking equipment. Unsurprisingly it was observed that whenever faces were present in the images, the observers gazed at them. Three different algorithms Saliency by Itti et al., GAFFE by Rajashekara et al., GBVS by Harel et al. were modified by addition of face saliency module to generate modified maps corresponding to each of the algorithms. Experimental gaze maps were analyzed and compared with modified saliency map, modified GAFFE map and modified GBVS map.
