System for Visually Disabled through Wearables Utilizing Arduino and Ultrasound

Vision loss is a major challenge that affects people's lives in many aspects. In order to help people with visual impairment navigate and interact with those around them, wearable electronic devices and innovative technology can be used. The visually impaired system using Arduino and ultrasound uses advanced technology to convert ultrasound waves into useful information for visual people. Wearable devices, such as glasses or mobile devices can be used to receive audio signals and convert them into notifications to the user, via vibration, sounds or even text messages, which are equipped with ultrasonic sensors. When wearable devices emit high-frequency audio signals, these signals bounce off various obstacles in the environment around the person. The feedback signals are received and converted into visual information or alert messages for the user. People with visual impairment face great challenges because they depend heavily on others for their mobility. In this paper, a model was created to support blind people, facilitate their mobility, and ensure their safety through timely alerts of any obstacles in their path. The project includes a portable device that uses Arduino and is equipped with several sensors, such as distance and temperature sensors, to detect objects whose temperature exceeds 0 degrees Celsius. This device is designed to be hand-held with the glove and belt attached at the waist. Integrating all the mentioned sensors along with the Arduino that supervises the process.
