Automated Head Turn Tracking and Other Innovations for VRA

描述(由申请人提供)：这项研究的总体目标是开发一种头部跟踪程序，用于使用视觉增强测听(VRA)自动评估婴儿的听力。头部跟踪程序将被整合到智能听力系统公司的智能视觉增强测听(IVRA)系统中。IVRA系统目前提供自动刺激传递、数据记录和增强，但依赖于审查员来判断是否存在反应。由于考官的反应标准可能不同，目前的VRA和IVRA结果包含一定程度的考官偏见，这可能会增加测试的变异性，并影响测试的有效性。拟议的自动头部跟踪程序将允许根据刺激强度和频率自动记录反应发生和反应时间，消除考官偏见，提高VRA的可靠性、有效性和可用性。I期临床研究将涉及30名婴儿。 公共卫生相关性：视觉增强测听(VRA)是确定婴儿听力状况的重要评估工具。所提出的自动头部跟踪程序在VRA中的实施有望极大地提高VRA测试的临床可靠性、有效性和实用性。因此，拟议的工作将通过开发更好的VRA测试系统来极大地影响公众健康。

DESCRIPTION (provided by applicant): The overall goal of this study is to develop a head tracking procedure for the automated assessment of hearing in infants using Visual Reinforcement Audiometry (VRA). The head tracking procedure will be incorporated into the Intelligent Visual Reinforcement Audiometry (IVRA) system from Intelligent Hearing Systems Corp. The IVRA system currently provides automated stimulus delivery, data recording, and reinforcement but relies on an examiner to judge the presence of responses. Because examiners can vary in their response criterion, current VRA and IVRA results include a certain amount of examiner bias, which can increase test variability and compromise test validity. The proposed automated head tracking procedure will allow for automated recording of response occurrence and reaction time as a function of stimulus intensity and frequency and eliminate examiner bias and increase the reliability, validity and availability of VRA. The Phase I clinical study will involve 30 infants. PUBLIC HEALTH RELEVANCE: Visual Reinforcement Audiometry (VRA) is an important assessment tool in determining the hearing status of infants. The implementation of the proposed automated head tracking procedure in VRA is expected to greatly improve the clinical reliability, validity and utility of VRA testing. As such, the proposed work will greatly impact public health by developing better VRA testing systems.
