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 视力障碍会导致行动不便、虚弱、疾病和过早死亡。这些机动性损失 与全球高达80%的失业率和严重的质量问题有关 生活质量(QOL)。在许多情况下，健康和幸福会受到任何形式的视力丧失和社会心理的影响 焦虑和抑郁等障碍是随着赤字扩大而增加的复合影响。害怕…… 跌倒是一种威胁，助长了这种向下的“螺旋”，而且往往不受控制；这种恐惧令人担忧 这是合理的，因为视力障碍会导致机械性绊倒、跌倒和长骨骨折的大幅增加。 这场完美的风暴让相当大一部分人变得贫穷，被剥夺了选举权，并经历了 不利的健康后果。这些令人震惊的事实，尽管在几乎每个高收入国家都是真实的，但实际上 在低收入和中等收入国家，如泰国，情况更为严重。当在基本功能级别上考虑时， 视觉障碍破坏了对我们三维世界和其中物体的信息的获取，导致 空间认知能力差和不能成功导航，无论是去工作的地方还是去 杂货店。先进的可穿戴设备提供了一个潜在的解决方案来缩小这一差距，并提供一致和 在导航过程中可靠地获取机动性和定位所需的信息。我们的团队是 帮助开发了一种新型可穿戴设备-VIS4ION(视障空间智能服务系统 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、人在船上的 循环、感知到反馈平台，以提供实时的功能帮助。我们的中心假设是 可穿戴设备支持视障(VI)人群的空间认知，增加个人自由和 机构，并促进健康和福祉。我们寻求通过下一代地图绘制来增强这项技术 和本地化软件，形成微服务以支持VI中的空间认知。我们将评估 该新方法的性能(例如，映射)及其对功能(例如，导航效率)的影响， 健康(例如，跌倒)和健康(例如，QOL)指标。该提案分两个阶段提出了五个目标，重点是 在全球环境中验证这一方法。首先，我们将实现语义分割和图像查询- 基于泰国小型园区的本地化网络，独立于环境(传感器、 基于)和Wi-Fi/蜂窝基础设施。然后，我们将在VI学生中部署这个增强的平台。第三，我们将 评估可接受性、适当性和可行性，重点是VIS4ION的经验。如果里程碑 满足第一阶段(R21)，我们将进入第二阶段(R33)。第四，我们将测试 改进后的系统在延长使用期内的有效性。最后，曼谷的一个额外的城区 将被选中并构建3D环境地图以进行概化测试，确保VIS4ION能够 使用不同的上下文元素处理多个位置。鉴于这一基础和计划中的进展，我们 预测该平台将大大降低跌倒和静止风险以及相关的不良健康后果。
