Download Effects of Peripheral Vision on Eye Movements: A Virtual by Elena Hitzel PDF

By Elena Hitzel

Elena Hitzel pursues the concept that human gaze destinations are prompted by way of at the moment non-fixated items which are obvious within the peripheral sight view. utilizing eye monitoring apparatus and a digital truth procedure to supply naturalistic projects, the writer indicates that gaze is biased in the direction of a neighboring item, particularly whilst this item is proper to the subject’s present job. this means that peripheral imaginative and prescient is utilized in the allocation of gaze in everyday life and that this bias should be interpreted by way of a compromise among foveal and peripheral details achieve. the advantage of this bias in typical imaginative and prescient is mentioned within the context of bottom-up and top-down theories.

2012). This nonperfect estimate of the current state might cause costs by executing actions, which do not result in a maximum reward. This costs needs to be avoided by making “correct” fixations. In terms of reward learning, the amount of positive loaded reward is reduced and therefore the frequency of “incorrect” fixations should be decreased. Thus, gaze is allocated to positions that will minimize the negative costs of uncertainty and consequently maximize the expected reward. , 2012). That means that when subjects are told to carry out a certain task, the subject’s reward, which motivates the particular actions, is simply the accomplishment of the task itself.

The next paragraphs will describe the experiment, which the current study is directly associated with. This experiment was conducted by Tong and Hayhoe in 2014. Subjects walked along a winding path through a virtual room with blue spheres and brown obstacles arranged along the path. Eye movement data and body movement data were assessed in four different tasks: The subjects had to 28 follow the path only, to collect blue target spheres, to avoid brown obstacle cubes or to collect the targets while avoiding the obstacles.

Second, a model of center accentuation, assigning the mean of a Gaussian function to the horizontal midpoint of the pattern. Third, a model of center attenuation, assigning an inverse Gaussian function to the horizontal midpoint of the pattern. And last, a model of neighbor proximity, assigning more weight to dots that did not have direct neighbors than to those dots that did. The results showed that only the weighted visual COG model described last led to a significant enhancement of predictions compared to the unweighted mean.
