Abstract

In this paper, we compare and analyze smart technologies and present six obstacle detection features to help visually impaired people walk. Traditionally, visually impaired people walk with the white cane or a guide dog. With the development of IoT technology, various smart walking aids systems have been developed. Those intelligent walking aids systems have obstacle-detecting systems and route-guidance systems. Many researchers are developing the walking aids system, which detects an obstacle and provides the obstacle information by haptic feedback. Also, they are designing the database server system to share the obstacle information. Particularly the composed system can quickly give an obstacle-avoidance route using shared obstacle information. Smart walking aids systems for visually impaired people will advance more rapidly by applying machine learning and intelligent systems.

본 논문에서는 시각장애인을 위한 이동보조시스템을 비교 분석하고, 6개의 장애물 감지 특징을 정리한다. 전통적으로, 시각장애인은 흰 지팡이를 사용하거나 안내견과 함께 보행한다. 최근 IoT 기술의 발달로 시각장애인의 보행을 보조하는 스마트 이동보조시스템이 개발되었다. 이러한 스마트 이동보조시스템은 장애물을 감지하고, 경로를 안내하는 역할을 수행해야 한다. 특히 스마트 이동보조 시스템은 장애물인지 판단하고, 햅틱 피드백을 통해 장애물 정보를 제공한다. 그리고 스마트 시스템은 서버를 구성하여 장애물의 정보를 저장하고, 다른 사용자에게 정보를 공유한다. 또한 저장된 장애물 정보를 통해 사용자 중심의 최적의 경로를 생성하여 시각장애인에게 장애물을 회피할 수 있는 경로를 안내한다. 스마트 이동보조시스템은 기계학습과 인공지능 기술을 적용함으로써 더욱 빠르게 발전할 것이다.
