This paper examines the possibility of a new warning method that would increase drivers’ sensitivity to hazardous factors in the driving environment. The method is based on a visual warning mark in the peripheral vision, called an ambient warning. In this study, the use of ambient visual marks is investigated. These marks are soft visual warnings and lack officious interference with the task performed in the central vision field. Experimentation with a 27-inch monitor display resulted in decreased response times for detecting a flashing mark when an ambient mark was shown in advance. The results suggest that information observed in the peripheral vision field could help people drive more safely.

This paper deals with the possibility of a new warning method for controlling drivers’ sensitivity for recognizing hazardous factors in the driving environment. The method is based on a visual warning cue in the peripheral vision, which is outside of the central vision. In the human visual field, the central and peripheral vision fields have different processing mechanisms. In this study, the presentation of visual cues in the peripheral vision field is intended to provide a soft visual warning without intrusive interference to the task performed in the central vision. The results of many experiments performed with a 27-in. monitor display showed that a blinking visual cue at a view angle of around 26° from the center provided a good visual stimulus in the peripheral vision without being overlooked or being annoying to the subjects. The subjects tended to perceive the visual stimulus in the peripheral vision field beginning at 60°. A visual cue moving from the outer vision field to the center vision was perceived at around 60° regardless of its speed. A preliminary design guideline for installing visual warnings in the peripheral vision field is proposed.

A second-order reversed-phi stimulus is composed of moving features (areas filled with texture) whose overall amount of texture-contrast is reversed between successive frames. In peripheral vision, the stimulus is perceived as moving in the reversed direction (opposite to the feature displacement). In central vision, it is perceived in the forward direction at low temporal frequencies but in the reversed direction at high temporal frequencies. Moving the observer away from the displays has the same effect as changing from central to periphery vision: reversed motion becomes more dominant. The illusion demonstrates the different properties of the second- and third-order motion systems.

After few seconds, a figure steadily presented in peripheral vision becomes perceptually filled-in by its background, as if it “disappeared”. We report that directing attention to the color, shape, or location of a figure increased the probability of perceiving filling-in compared to unattended figures, without modifying the time required for filling-in. This effect could be augmented by boosting attention. Furthermore, the frequency distribution of filling-in response times for attended figures could be predicted by multiplying the frequencies of response times for unattended figures with a constant. We propose that, after failure of figure–ground segregation, the neural interpolation processes that produce perceptual filling-in are enhanced in attended figure regions. As filling-in processes are involved in surface perception, the present study demonstrates that even very early visual processes are subject to modulation by cognitive factors.

The paper presents a concept of lifelong plasticity of peripheral vision. Central vision processing is accepted as critical and irreplaceable for normal perception in humans. While peripheral processing chiefly carries information about motion stimuli features and redirects foveal attention to new objects, it can also take over functions typical for central vision. Here I review the data showing the plasticity of peripheral vision found in functional, developmental, and comparative studies. Even though it is well established that afferent projections from central and peripheral retinal regions are not established simultaneously during early postnatal life, central vision is commonly used as a general model of development of the visual system. Based on clinical studies and visually deprived animal models, I describe how central and peripheral visual field representations separately rely on early visual experience. Peripheral visual processing (motion) is more affected by binocular visual deprivation than central visual processing (spatial resolution). In addition, our own experimental findings show the possible recruitment of coarse peripheral vision for fine spatial analysis. Accordingly, I hypothesize that the balance between central and peripheral visual processing, established in the course of development, is susceptible to plastic adaptations during the entire life span, with peripheral vision capable of taking over central processing.
