Engaging in recreational activities in public spaces poses challenges for
blind people, often involving dependency on sighted help. Window shopping is a
key recreational activity that remains inaccessible. In this paper, we
investigate the information needs, challenges, and current approaches blind
people have to recreational window shopping to inform the design of existing
wayfinding and navigation technology for supporting blind shoppers in
exploration and serendipitous discovery. We conduct a formative study with a
total of 18 blind participants that include both focus groups (N=8) and
interviews for requirements analysis (N=10). We find that there is a desire for
push notifications of promotional information and pull notifications about
shops of interest such as the targeted audience of a brand. Information about
obstacles and points-of-interest required customization depending on one's
mobility aid as well as presence of a crowd, children, and wheelchair users. We
translate these findings into specific information modalities and rendering in
the context of two existing AI-infused assistive applications: NavCog (a
turn-by-turn navigation app) and Cabot (a navigation robot).

对视觉障碍者参与公共空间的娱乐活动存在依赖视力帮助的挑战，其中包括无法参与的购物活动。本文通过研究盲人对娱乐购物的信息需求、挑战和现有方法，旨在为设计现有的导航技术提供支持，帮助盲人购物者进行探索和偶然发现。通过对 18 名盲人参与者进行形成性研究，包括焦点小组和需求分析访谈，我们发现盲人希望获得促销信息的推送通知，以及关于感兴趣店铺的拉取通知，例如品牌的目标受众。关于障碍物和兴趣点的信息需要根据个人的移动辅助设备以及人群、儿童和轮椅使用者的存在进行自定义。我们将这些发现应用于两个现有的 AI 辅助应用程序（NavCog 和 Cabot），具体包括信息模态和渲染方面。
