Head-mounted Positional Management System

描述(由申请人提供)： 我们计划开发一个用于诊断和治疗前庭疾病的头盔位置管理系统(HPM系统)，以便在医疗和研究设施中广泛应用。利用可以跟踪头部运动的空间方位传感器，结合最先进的3-D眼动记录和分析方法，该系统将分析眼睛运动(眼球震颤)和头部的空间方位，显示数据，并提供解释性指南，帮助操作员在检查台上手动执行复杂的重新定位动作。在第一阶段，我们将设计一款无线原型耳机，将头部跟踪系统与视频眼震分析和监控系统结合在一起，以图形方式显示受试者半规管正在进行的空间方位，并指示是哪条半规管造成了眼震。决策支持系统将在进行诊断和治疗动作时提供指导(图形、文本)，并将监控用户动作的精确度。我们还将通过在一个患有位置性眩晕的小型受试者队列(n=15)中进行可行性研究，通过演示HPM系统的附加值来验证性能。我们将通过确定HPM系统与使用最好的商业设备进行诊断和治疗相比的附加值来验证性能。 在第二阶段，我们预计将根据第一阶段的调查结果对耳机进行工程修改。其他系统将被添加到耳机上，或作为外围模块，以开发先进的决策支持系统。将在几个测试点安装生产模型，以便在更大的受试者群体中进行人体研究，以获得更明确的验证和用户接受度测试。

DESCRIPTION (provided by applicant): We plan to develop a Head-mounted Positional Management System (HPM System) for diagnosis and treatment of vestibular disorders for widespread application at medical and research facilities. Utilizing a spatial orientation sensor that can track head movement, coupled with state-of-the-art 3-D eye movement recording and analysis methods, the system will analyze eye movement (nystagmus) and spatial orientation of the head, display the data, and provide interpretive guidelines to assist the operator in carrying out complex repositioning maneuvers manually on an exam table. During Phase I we will design a wireless prototype headset combining a head-tracking system with a video nystagmus analysis and monitoring system to display graphically the ongoing spatial orientation of the subject's semicircular canals and indicate which semicircular canal is creating the nystagmus. A decision support system will offer guidance (pictorial, textual) in undertaking diagnostic and treatment maneuvers, and will monitor the precision of the user's maneuvers. We will also validate performance by demonstrating the added value of the HPM System by performing feasibility studies in a small subject cohort (n=15) with positional vertigo. We will validate performance by determining the added value of the HPM System compared to diagnosis and treatment with the best commercially available equipment. During Phase II, we anticipate that engineering modifications of the headset will be made based upon Phase I findings. Additional systems will be added to the headset, or as peripheral modules, to develop an advanced decision support system. Production models will be installed at several beta sites for conduction of human studies in a larger subject population to obtain more definitive validation and user acceptance testing.
