Abstract

The spatial behavior of passersby can be critical to blind individuals to initiate interactions, preserve personal space, or practice social distancing during a pandemic. Among other use cases, wearable cameras employing computer vision can be used to extract proxemic signals of others and thus increase access to the spatial behavior of passersby for blind people. Analyzing data collected in a study with blind (N=10) and sighted (N=40) participants, we explore: (i) visual information on approaching passersby captured by a head-worn camera; (ii) pedestrian detection algorithms for extracting proxemic signals such as passerby presence, relative position, distance, and head pose; and (iii) opportunities and limitations of using wearable cameras for helping blind people access proxemics related to nearby people. Our observations and findings provide insights into dyadic behaviors for assistive pedestrian detection and lead to implications for the design of future head-worn cameras and interactions.

通过头戴式摄像头获取路人近距离信号:盲人的机会和限制。
在大流行期间,路人的空间行为对盲人发起互动、保持个人空间或保持社交距离至关重要。在其他用例中,采用计算机视觉的可穿戴摄像头可用于提取他人的近距离信号,从而增加盲人对行人空间行为的访问。通过对盲人(N=10)和正常人(N=40)的研究数据进行分析,我们探讨了:(i)头戴式摄像头捕捉到的接近行人的视觉信息;(ii)行人检测算法,用于提取邻近信号,如行人存在、相对位置、距离和头姿;(三)使用可穿戴相机帮助盲人获取与周围人相关的近距信息的机会和局限性。我们的观察和发现为辅助行人检测的二元行为提供了见解,并对未来头戴式摄像头和交互的设计产生了影响。
