Abstract: One of the biggest problems faced by the visually impaired is navigating from place to place, be it indoors or outdoors. They have to be alert at all times to avoid consequences like colliding with stable or moving obstacles, ascending or descending staircases. Also, at times they may be in distress and might want to send an alert message to their relatives or friends about their whereabouts. These problems of blind people can be addressed with the intervention of technology. Although efforts have been made to provide innovative solutions for the blind, these solutions' shortcomings mean that the issues faced by those who are visually impaired remain unresolved. Hence, one of the competent solutions is to use embedded system. The proposed solution employs the WSN to provide a medium between the blind and the environment. Several sensors can be used to detect anomalies like obstacles, staircases.
