论文摘要
导航和避免障碍物是视力障碍最艰巨的任务。最近的研究项目提出了解决此问题的技术解决方案。到目前为止，大多数系统在各种照明条件下工作时无法提供多维反馈。我们通过将3D摄像头与触觉反馈套合相结合，提出了一种新颖的避免障碍系统。我们的系统使用相机的距离信息，并将其映射到前臂上的2D振动阵列上。在我们对触觉反馈套筒的功能测试中，用户能够正确识别并定位98,6％的单电机振动模式，以及70％的多向和多运动振动模式。在黑暗中的测试路线上评估了组合障碍物的组合系统，并模拟了导航任务。所有用户都能够完成任务，并在多个运行中显示出性能的改进。该系统独立于照明条件，可以在室内和室外使用。因此，避免障碍系统展示了一种有前途的方法，即使用技术使视力障碍更具独立性。
Navigation and obstacle avoidance are some of the hardest tasks for the visually impaired. Recent research projects have proposed technological solutions to tackle this problem. So far most systems fail to provide multidimensional feedback while working under various lighting conditions. We present a novel obstacle avoidance system by combining a 3D camera with a haptic feedback sleeve. Our system uses the distance information of the camera and maps it onto a 2D vibration array on the forearm. In our functionality tests of the haptic feedback sleeve, users were able to correctly identify and localize 98,6% of single motor vibration patterns and 70% of multidirectional and multi-motor vibration patterns. The combined obstacle avoidance system was evaluated on a testing route in the dark, simulating a navigation task. All users were able to complete the task and showed performance improvement over multiple runs. The system is independent of lighting conditions and can be used indoors and outdoors. Therefore, the obstacle avoidance system demonstrates a promising approach towards using technology to enable more independence for the visually impaired.
