المستخلص

The blind and visually impaired people represent a special segment of society where they suffer from a lack of independence, especially in movement, due to the presence of many obstacles, as they find it difficult to recognize objects in their path. To solve this problem, blind and visually impaired people resort to using the white stick, which allows them to perceive the surrounding environment within the limits reached by the stick. In this research, a smart stick has been developed using an (Arduino) chip to help them by locating the current location of the holder in case of his long absence by using a Global Positioning System (GPS). As for avoiding obstacles, it is done using ultrasonic sensors, and blind people are alerted through audio clips to help them navigate and choose the appropriate path. Blind people can also send an SMS text message of their current location to a specified phone number of a relative in case they need assistance using the Global System for Mobile Communications (GSM). Finally, the proposed structure was experimentally validated by the results of the experimental work obtained from the prototype built and implemented in our laboratory.
