Wearable obstacle detection device for visually impaired people

In this paper the prototype of wearable obstacle detection system for visually impaired persons is proposed. Solution is based on ultrasonic sensor collecting data about surrounding obstacles. Acquired information is processed with microcontroller and distance to obstacle is provided to the user via audio signal. Since the sensor can be easily attached to various kinds of clothes, the device can detect the obstacles of different heights depending on the user’s need. Device has low weight and compact dimensions what makes it a wearable and discrete tool that could provide valuable information about user environment.
