In this and in the following two studies, distracter stimuli were presented surrounding the target in the center of screen, occupying a region less than 12 cm in diameter, so that stimuli would fit well within the participant's visual field (see Bargh & Chartrand, 2000) but could not be foveated as easily as the entire stimulus array in the classic flanker.
In particular, data were analyzed to determine whether the effect of distraction was to disrupt visual scanning, increasing the probability that observers would fail to fixate the changing region of an image, or to degrade the attentive encoding and transfer of foveated visual information into memory.
When the point of the arrow is foveated, many more cortical cells will process information about the point than will fire to the rest of the arrow, even if the tail is many times larger than the point.

For the display itself, Google and LG used a custom driver integrated circuit and also highlighted a foveated rendering method to power it more efficiently.
In comparison to the Mali-G71, the G72 offers an improvement of 25 percent in power efficiency, a 17 percent ML efficiency gain, and 20 percent better area efficiency, and also includes improved support for mobile multiview systems, multisampling anti-aliasing, foveated rendering and Adaptive Scalable Texture Compression (ASTC), which is used to increase image compression quality in order to save power.

If the eye movement does not reach the same angular velocity as the object, it cannot be foveated, and its image blurs.
