An Automated System to Locate Items Misplaced by Persons with Dementia in a Care Facility

摘要 此应用程序直接响应PAR-18-588 SBIR资助机会公告的目的 （FOA）.本项目将开发一个辅助系统，供痴呆症患者的照顾者定位 被残疾人放错地方的物品。一个把东西放错地方的残疾人会产生焦虑感， 残疾人和护理人员的挫折感。PWD可以将物体留在非常不寻常的地方。的 PWD还可以隐藏对象并忘记它们放在哪里。重复搜索对象会消耗 记忆护理机构的工作人员的时间。本项目第一阶段将开发超宽带（UWB）标签 这项技术允许护理人员在记忆护理设施中快速定位标记的物体，范围在1英尺以内。使用 智能手机或平板电脑，护理人员将能够从标记的对象列表中进行选择， 房间和房间内的位置，以找到错位的对象。系统还会追踪 引导他们快速找到目标。这将是特别有帮助的时候， 目标不在视线范围内。该系统还可以用于在对象已经从护理人员的位置移动时向护理人员报警。 房间里，它应该保持。标签将是硬币大小，并附在对象。第一阶段的目标是 将开发用于UWB标签的技术，用于跟踪标签的节点，系统软件计算 标签位置和移动的应用程序来向护理人员显示对象位置。第一阶段将进行 在记忆护理机构与护理人员进行访谈，以确定他们的需求。第二阶段将进行研究， 存储器维护设施，并在商业化之前为最终系统修改获得员工反馈。

Abstract This application responds directly to the purpose of the PAR-18-588 SBIR Funding Opportunity Announcement (FOA). This project will develop an assistive system for caregivers of persons with dementia (PWD) to locate items that have been misplaced by PWD. A PWD who misplaces objects can create feelings of anxiety and frustration for both the PWD and the caregivers. The PWD can leave an object in a very unusual place. The PWD can also hide objects and forget where they put them. Repeatedly searching for objects can consume time for the staff at a memory care facility. This phase I project will develop an Ultrawide Band (UWB) tag technology to allow caregivers to quickly locate tagged objects in a memory care facility to within 1 foot. Using a smartphone or tablet computer, a caregiver will be able to select from a list of tagged objects and be shown the room and the position within the room to find the misplaced object. The system will also track the position of the staff person to guide them quickly to the object. This would be particularly helpful when the misplaced object is not in plain sight. The system can also be used to alert caregivers if an object has been moved from a room where it is expected to remain. The tags will be coin size and attached to the object. The phase I aims will develop the technology for the UWB tag, the nodes used for tracking the tags, system software to compute the tag position and the mobile application to show the caregiver the object location. The phase I will conduct interviews with caregivers at memory care facilities to identify their needs. The phase II will conduct studies in memory care facilities and obtain staff feedback for final system modifications prior to commercialization.
