“…Lin et al [38] found a highly positive correlation between subjective discomfort caused by luminance contrast and eye movement speed, which was consistent with our findings, that is, in the higher luminance contrast, the eye kept moving with a stronger feeling of glare. Pakkert et al [39] concluded in their study that presenting a small number of lights yielded improvement would not show in the task performance. The author said that it was hard to determine the specific effect of the glare caused by extreme luminance contrast on the observer's eye because the human body could make a "strategic adaptation", our findings partially confirmed this conclusion.…”

This paper investigated the effect of luminance contrast between sign and surrounding object on the gaze behavior of pedestrian, static or dynamic 360° panorama rendered in a virtual environment applied to simulate the wayfinding of pedestrians in the metro stations. Fifty-five participants observed the sign posters and the advertisement boards with distinct luminance contrasts (31 of them were in static levels, 24 of the rest were in dynamic levels) and were asked to point out the graphic or textual changes in the area after 30s. The eye tracker recorded ocular data, and glare perception was inquired by questionnaire. The result of T-test and Regression analysis revealed that luminance contrast was a saliency feature distinguishing visual targets and surrounding objects. The correlation between the value of luminance contrast and fixations, fixation durations on the sign is negative. Each increase in luminance contrast by one unit reduces the mean of fixations by 0.826, accompanied by a stronger feeling of glare, which indicated the strategic adaption of visual attention. The study contributed to our understanding of a new sight of lighting design in public traffic places and confirmed that lighting simulation in an immersive virtual environment can effectively analyzes visual perception.

“…Possible explanations for this higher state of arousal include that more higher cognitive load is associated with walking alone at free speed, such as way-finding and orientation, whereas these processes are not needed while following a person. Two studies by Amougum and colleagues 43 , 49 show increased physiological responses when using cognitive processes in real-life travel experience and also in virtual reality travel experience. Additionally, people walking alone might have felt more insecure about whether they were performing the experiment “correctly” and might have felt observed by the experimenter.…”

“…Thus, working memory is responsible for such processes as way-finding and orientation, but also responsible for paying attention to others. A study by Armougum and colleagues 43 shows that working memory activity is also associated with increased physiological response while way-finding. Furthermore, walking in a dense crowd might also increase concerns of being pushed or hurt by others (for example, if they step on your feet).…”

The connection between stress, density, and speed in crowds

Moving around in crowds is part of our daily lives, and we are used to the associated restriction of mobility. Nevertheless, little is known about how individuals experience these limitations. Such knowledge would, however, help to predict behavior, assess crowding, and improve measures for safety and comfort. To address this research gap, we conducted two studies on how constrained mobility affects physiological arousal as measured by mobile electrodermal activity (EDA) sensors. In study 1, we constrained walking speed by externally imposing a specific walking speed without physical proximity to another person, while, in study 2, we varied walking speed by increasing the number of people in a given area. In study 1, we confirmed previous findings showing that faster speeds led to statistically significantly higher levels of physiological arousal. The external limitations of walking speed, however, even if perceived as uncomfortable, did not increase physiological arousal. In the second study, subjects’ speed was gradually reduced by density in a single-lane experiment. This study shows that physiological arousal increased statistically significant with increasing density and decreasing speed, suggesting that people experience more stress when their movement is restricted by proximity to others. The result of study 2 is even more significant given the results of study 1: When there are no other people around, arousal increases with walking speed due to the physiology of walking. This effect reverses when the speed must be reduced due to other people. Then the arousal increases at lower speeds.

“…Added to this problem is the challenge of concurrently managing multimodal sensory stimuli, which can lead to processing demand overload and interference with normal cognitive processing. This sensory overload, or sensory processing flooding effect, can be found in cognitively unimpaired persons ( 120 ) and in diseases such as schizophrenia ( 121 ), but is magnified in disorders such as MS and mTBI that feature pathological sensory processing and cognitive impairment resulting from damaged WM.…”

The ability to simultaneously process and integrate multiple sensory stimuli is paramount to effective daily function and essential for normal cognition. Multisensory management depends critically on the interplay between bottom-up and top-down processing of sensory information, with white matter (WM) tracts acting as the conduit between cortical and subcortical gray matter (GM) regions. White matter tracts and GM structures operate in concert to manage both multisensory signals and cognition. Altered sensory processing leads to difficulties in reweighting and modulating multisensory input during various routine environmental challenges, and thus contributes to cognitive dysfunction. To examine the specific role of WM in altered sensory processing and cognitive dysfunction, this review focuses on two neurologic disorders with diffuse WM pathology, multiple sclerosis and mild traumatic brain injury, in which persistently altered sensory processing and cognitive impairment are common. In these disorders, cognitive dysfunction in association with altered sensory processing may develop initially from slowed signaling in WM tracts and, in some cases, GM pathology secondary to WM disruption, but also because of interference with cognitive function by the added burden of managing concurrent multimodal primary sensory signals. These insights promise to inform research in the neuroimaging, clinical assessment, and treatment of WM disorders, and the investigation of WM-behavior relationships.
