TheiaVision: ultrasonic glasses for people with visual impairment

Abstract

There are a lot of people living in the world, whose eyesight is either very poor or who cannot see at all. People with visual impairment have a wide variety of tools and other resources available to them. The exact choice depends on the specific needs and vision remainder of the individual. However, most of these devices have some form of disadvantage to them, whether it is high price or the fact that they are mostly seer-oriented, with only some applications to expand their capabilities to also make them helpful to the blind and visually impaired community. TheiaVision is a system that was developed in the course of this thesis, which actively monitors the immediate surroundings of the individual with the help of ultrasonic sensors. Based on the measurements obtained, the system warns the user of obstacles that are in a too close proximity, thus helping people with vision disorders navigate the environment a bit easier. The system can be developed further by adding various features, such as GPS navigation and voice commands, to further simplify the life of the user
