经历视力丧失的人数一直在迅速增加，导致对辅助技术研究的极大兴趣。随着配备摄像头和传感器的可穿戴设备的出现，这些技术集成了多种硬件和软件工具来帮助盲人。本文介绍了Ebsar，一个阿拉伯语的导航辅助与光学头戴式显示器，指导盲人室内。该应用程序通过跟踪建筑物内有视力的人的移动来构建室内地图，生成并打印兴趣点的QR码位置标记，然后为盲人用户提供阿拉伯语的语音指导。一项用户接受度研究表明，Ebsar应用程序易于使用，其中15名视力正常的人评价了地图构建过程，9名盲人用户评价了导航系统的可用性和有效性。(C)2016爱思唯尔有限公司版权所有
The number of people experiencing vision loss has been increasing rapidly, leading to great interest in assistive technologies research. Together with the emergence of wearable devices equipped with cameras and sensors, these technologies integrate multiple hardware and software tools to help the blind. This paper describes Ebsar, an Arabic navigation aid with an optical head-mounted display that guides blind people indoors. The application constructs indoor maps by tracking the movements of a sighted person inside a building, generates and prints QR code location markers for points of interest, and then provides voice guidance in Arabic to blind users. A user acceptance study, in which 15 sighted people evaluated the map construction process and 9 blind users evaluated the guidance system's usability and effectiveness, demonstrated the ease of use of the Ebsar application.
