Abstract :

Visual impairment is characterized by the decrease in functional abilities of eyesight causing increase in dependencies. Recently many systems have been developed to help visually impaired people for making them self-dependable during their daily living activities. A walker design concept provides direction assistance to visually impaired people for their obstacle free movement. In this article, a new hardware design concept is proposed to help visually impaired people. The system is made possible by the use of different sensors mounted on walker at various positions. Infrared sensors and ultrasonic sensor detects obstacles in front of them and provides directional information about it to the microcontroller. In response system will trigger an audible notification via earphone to alert the visually impaired person if there is an obstacle. Accelerometer sensor alerts the visually impaired person about the possibility of fall due to stuck or potholes by the buzzer sound indication as well as by the audible notification. Since many walkers available in the market are heavy in weight and requires training to use, proposed smart walker provides reliability in carrying it with easy to handle phenomenon.
