Abstract :
We propose smart backpack to guide to destination safely for visually impaired person. To estimate the current position of the blind is very important. We use Zigbee modules that estimate the distance using the signal strength in transmission and reception period. We build a grid-based local area map for guiding user. In addition, we use ultrasonic sensors for detecting obstacles and analysing the spatial environment in front of user. We make a backpack type wearable system by integrating these technologies for the convenient outdoor walking.
