Emergency Egress Locator

描述（由申请人提供）：该项目将开发和鉴定一种新的辅助技术，以帮助盲人。紧急出口指示灯（EEL）将在紧急情况下为出口提供指引。来自普通出口标志的照明将被调制以携带引导信息，同时仍然是完全可见的，并且作为出口标志起作用。盲人将携带或佩戴基于手机的接收器作为计算平台，该平台处理来自出口标志的光学信号并向盲人提供音频引导。如果一些出口因紧急情况而被封锁，联网的EEL出口标志将重新配置，以引导用户到安全区域。EEL将是廉价和易于实施，因为它将使用现有的出口标志。EEL将在商业设施中进行演示，并与盲人旅行者进行评估。它的辅助能力和与其他辅助技术的比较将被定量测量。该项目将开发一个系统，帮助盲人在紧急情况下安全、快速地找到出口。普通的出口标志将被修改，以提供位置和指导的人谁是盲人和手机定位器将提供寻路音频指导。盲人将能够更加安全和独立地旅行。

DESCRIPTION (provided by applicant): This project will develop and qualify a new assistive technology to aid persons who are blind. The Emergency Egress Locator (EEL) will provide guidance to exits under emergency conditions. The illumination from ordinary exit signs will be modulated to carry the guidance information while still being totally visible and functional as an exit sign. Persons who are blind will carry or wear a receiver based on a cellphone as a computing platform which processes the optical signal from the exit sign and provides audio guidance to the person who is blind. If some exits are blocked by emergency, the networked EEL exit signs will reconfigure themselves to lead users to a safe area. EEL will be inexpensive and easy to implement because it will use existing exit signs. EEL will be demonstrated in a commercial facility and evaluated with blind travelers. Its assistive capability and comparison with other assistive technologies will be quantitatively measured. This project will develop a system to help persons who are blind find their way to exits safely and quickly in case of emergency. Ordinary exit signs will be modified to provide location and guidance to persons who are blind and cellphone based locators will provide wayfinding audio guidance. Persons who are blind will be able to travel more safely and independently.
