Abstract

Walking indoors, particularly at home, presents a distinct experience compared to the conventional pedestrian walking classically described. Our homes encompass intricate, confined, and cluttered architectural spaces that necessitate a predominantly curvilinear walking pattern. Despite the growing interest in studying our home, spurred by successive COVID-19 lockdowns, there remains a dearth of information regarding our walking behaviors inside homes, yet rich in data on the physical and sensory links between humans and their daily interior environment.This study presents the outcomes of a controlled experiment conducted in an apartment in Montpellier, France. Participants were tasked with traversing the living room at a natural pace, encountering two natural obstacles-a large dining table and a small coffee table. They then walked back in opposite direction, circumnavigating the same two obstacles. To examine walking behavior within a pseudo-natural context, three conditions were tested: a controlled condition and two conditions that perturbed the natural curvilinear trajectory perceptually, by imposing an unpleasant sound, or physically, by suddenly displacing the coffee table between conditions. Twenty participants performed 30 trials in each condition. We approximated the position of their center of mass and computed various metrics related to their trajectories, including walking speed, obstacle clearance distance, its adaptation over time, and inter-trial trajectory variability.Findings revealed a greater visual clearance distance for the dining table compared to the coffee table, a difference reduced by the perturbation caused by displacing the coffee table. This clearing distance diminished with repetitions, showing that over time we tend to walk closer to obstacles around us. These adaptations were clearly the result of an active visuo-motor regulation, as evidenced by the reduced trajectory variability at, or just before, the location of the obstacles.Collectively, these results demonstrate that walking at home is a flexible behavior necessitating continuous perceptual adaptations in our daily trajectories. These findings could contribute to a detailed analysis of walking indoors under natural conditions, and the investigated metrics could serve as a baseline for comparing the embodiment of physical and mental health in walking patterns, for instance during lockdowns. Furthermore, our findings have consequences for safer mediated human architecture interaction.
障碍塑造了我们在家行走的方式
在室内行走,尤其是在家里,与传统的步行相比,呈现出一种独特的体验。我们的住宅包含复杂、狭窄和杂乱的建筑空间,需要以曲线为主的步行模式。尽管在连续的COVID-19封锁的刺激下,人们对研究我们的家庭越来越感兴趣,但关于我们在家中行走行为的信息仍然缺乏,但关于人类与其日常室内环境之间的物理和感官联系的数据却很丰富。这项研究展示了在法国蒙彼利埃的一间公寓里进行的一项对照实验的结果。参与者的任务是以自然的速度穿过客厅,遇到两个自然的障碍物——一张大餐桌和一张小咖啡桌。然后他们朝相反的方向走回去,绕过同样的两个障碍。为了检查在伪自然环境中的行走行为,测试了三种条件:一种是受控条件,另一种是在感知上干扰自然曲线轨迹的两种条件,一种是施加不愉快的声音,另一种是在物理上突然移动咖啡桌。20名参与者在每种情况下进行了30次试验。我们估计了它们的质心位置,并计算了与它们的轨迹相关的各种指标,包括行走速度、过障距离、其随时间的适应性和试验间轨迹可变性。研究结果显示,与咖啡桌相比,餐桌的视觉间隙距离更大,这一差异由于移动咖啡桌造成的扰动而缩小。这种清除距离随着重复而减少,这表明随着时间的推移,我们倾向于走得更靠近周围的障碍物。这些适应显然是一种积极的视觉运动调节的结果,正如在障碍物位置处或之前减少的轨迹可变性所证明的那样。总的来说,这些结果表明,在家走路是一种灵活的行为,需要在我们的日常轨迹中不断地进行感知适应。这些发现有助于对自然条件下室内行走的详细分析,所调查的指标可以作为比较行走模式(例如在封锁期间)的身心健康体现的基线。此外,我们的研究结果对更安全的人类建筑互动有影响。
