Abstract

Visually impaired people struggle with detecting obstacles in their upper body region which cannot be noticed by a common white cane. Therefore, we introduce the sensaid backpack, an obstacle detection system for blind people which covers head-to-hip region. Detection is based on ultrasonic sensors and feedback is given by vibration and audio within a distance of 1.5m and 0.7m, respectively. In a technical test the functionality and reliability were proven. The detection rate was determined at 94.4% in a practical user test. A limited detection rate was found for objects not perpendicular to the sensing device.
