When blind people walk, they need the help of a white cane or a guide dog. However, there are limitations that they have a trrouble in recognizing obstacles higher than chest level and only a few blind people can receive help from a guide dog. In this paper, we materialized glasses using an ultrasonics sensor which is able to help blind people walk safely. The system we propose is designed to offer information about risk factors visually, acoustically and tactually. The information is delivered in different intensity, such as turning on and off a LED, a buzzer and a vibrator motor, depending on the distance from an obstacle which is recognized with an ultrasonic sensor.
