Porle Artificial Intelligence Research Group School of Engineering and Information Technology Universiti Malaysia Sabah Locked Bag 2073 Kota Kinabalu 88999 Sabah Malaysia Email rlyn39@ Received 29 December 2003 Revised 29 November 2004 We present an object identification methodology applied in a navigation assistance for visually impaired NAVI system. The NAVI has a single board processing system SBPS a digital video camera mounted headgear and a pair of stereo earphones. The captured image from the camera is processed by the SBPS to generate a specially structured stereo sound suitable for vision impaired people in understanding the presence of objects obstacles in front of them. The image processing stage is designed to identity the objects in the captured image. Edge detection and edge-linking procedures are applied in the processing of image. A concept of object preference is included in the image processing scheme and this concept is realized using a fuzzy-rule base. The blind users are trained with the stereo sound produced by NAVI for achieving a collision-free autonomous navigation. Keywords and phrases blind navigation edge detection object identification fuzzy-rule-based stereo sound. 1. INTRODUCTION
