PROJECT SUMMARY/ABSTRACT Visual impairment engenders mobility losses, debility, illness and premature mortality. These mobility losses have been associated with unemployment rates that reach 80% globally and to severe compromises in quality of life (QoL). In many cases, health and wellbeing are ‘attacked’ by vision loss in any form factor and psychosocial barriers such as anxiety and depression are compounding influences that increase as deficits scale. The fear of falling is a threat that contributes to this downward ‘spiral’ and often goes unchecked; this fear is alarmingly justified, as visual impairment precipitates substantial increases in mechanical trips, falls and long-bone factures. This perfect storm leaves considerable swaths of the population poor, disenfranchised, and experiencing adverse health outcomes. These startling facts, although true in almost every high-income country, are even more severe in low- and middle-income countries, such as Thailand. When considered at a basic functional level, visual impairment destroys access to information about our three-dimensional world and the objects in it, leading to poor spatial cognition and an inability to navigate successfully, whether that be to a place of employment or a grocery store. Advanced wearables provide a potential solution to close this gap and provide consistent and reliable access to the information needed for mobility and orientation during navigation. Our team was instrumental in developing a novel wearable - VIS4ION (Visually Impaired Smart Service System for Spatial Intelligence and Onboard Navigation), a personal mobility solution that serves as a customizable, human-in-the- loop, sensing-to-feedback platform to deliver functional assistance in real-time. Our central hypothesis is that wearables support spatial cognition in visually impaired (VI) populations, augmenting personal freedom and agency, and promoting health and wellbeing. We seek to enhance this technology with next-generation mapping and localization software fashioned into a microservice to support spatial cognition in the VI. We will assess the performance of this new approach (e.g., mapping) as well as its impact on function (e.g., navigation efficiency), health (e.g., falls), and wellness (e.g., QoL) metrics. The proposal has five aims in two phases focused on validating this approach in a global setting. First, we will implement semantic segmentation and image-query- based localization networks in a small Thai campus to operate independently of both environmental (sensor- based) and Wi-Fi/cell infrastructure. We will then deploy this augmented platform with VI students. Third, we will assess for acceptability, appropriateness, and feasibility, focusing on experiences with VIS4ION. If milestones are met for this first phase (R21), we will progress to the second phase (R33). Fourth, we will test the effectiveness of the improved system over an extended-use period. Lastly, an additional urban area in Bangkok will be selected and 3D environmental map built for generalizability testing, ensuring that VIS4ION is able to handle multiple locations with disparate contextual elements. Given this foundation and planned advances, we predict the platform will substantially mitigate fall and immobility risks and associated adverse health outcomes.

项目摘要/摘要 视觉障碍会导致流动性损失，困难，疾病和过早死亡。这些移动性损失 与全球范围达到80％的失业率有关，质量严重妥协 生命（QOL）。在许多情况下，健康和福祉受到任何形式和社会心理的视力丧失的“攻击” 焦虑和抑郁之类的障碍是随着定义规模而增加的复杂影响。恐惧 跌倒是一种威胁，导致了这种“螺旋式”，并且常常不受组织。这种恐惧令人震惊 合理的是，随着视觉障碍会导致机械旅行，跌落和长骨的尸体大幅增加。 这场完美的风暴使人口贫穷，被剥夺权利和经历 不利的健康结果。这些开始事实，尽管几乎在每个高收入国家中都是如此 在泰国等低收入和中等收入国家中更为严重。当在基本功能级别上考虑时 视觉障碍破坏了有关我们三维世界及其物体的信息的访问 无论是在工作地点还是一个工作地点 杂货店。先进的可穿戴设备提供了缩小此差距并提供一致和的潜在解决方案 可靠地访问导航期间移动性和方向所需的信息。我们的团队是 有助于开发一种新颖的可穿戴 - Vis4ion（空间视觉障碍的智能服务系统） 智能和车载导航），这是一种个人移动解决方案，可作为可定制的，人类 循环，灵敏度对反馈平台，以实时提供功能援助。我们的中心假设是 可穿戴设备支持视力障碍（VI）人群中的空间认知，增强个人自由和 代理，促进健康和福祉。我们试图通过下一代映射来增强这项技术 和本地化软件被制成微服务，以支持VI中的空间认知。我们将评估 这种新方法的性能（例如，映射）及其对功能的影响（例如导航效率）， 健康（例如瀑布）和健康（例如QOL）指标。该提议在两个阶段的目标五个目标 在全球环境中验证这种方法。首先，我们将实施语义细分和图像Query-- 基于泰国小型校园的基于本地化网络，可独立于环境（传感器） 基于）和Wi-Fi/Cell基础架构。然后，我们将与VI学生一起部署这个增强平台。第三，我们会的 评估可接受性，适当性和可行性，专注于Vis4ion的经验。如果里程碑 在第一阶段（R21）中满足，我们将发展到第二阶段（R33）。第四，我们将测试 在延长的时期内改进系统的有效性。最后，曼谷的另一个城市地区 将被选中并为概括性测试而构建的3D环境图，以确保Vis4ion能够 处理具有不同上下文元素的多个位置。鉴于这个基础并计划进步，我们 预测该平台将大大减轻跌倒和固定的风险以及相关的不良健康结果。
