Desarrollo de un bastón electrónico para mejorar la movilidad de personas con discapacidad visual apoyado mediante visión artificial.

Abstract

The electronic cane supported with artificial vision improves the mobility and safety of visually impaired people; it is equipped with an embedded system, which allows the control of all systems for the detection of obstacles, text messages with location and detection of shapes with artificial vision. It has a vibrating motor for detecting obstacles, a camera for recognizing shapes and sounds to guide the person on safe routes. For the first part it was determined to make the variation of vibration inversely to the distance of the obstacle to determine the proximity to it in the route; the location system has two alternatives. The first, in the case of wanting to know the location of the person, the relative sends a text message, the system recognizes the location and responds with a text message to access through the Google Maps application. The second alternative is guided for emergency situations when the person requires help through the panic button is sent from your location to an emergency contact. Artificial vision makes it possible to recognize the arrows that are placed on the ground for safe routes established for the visually impaired and are guided through audio with headphones. The operational and validation tests were carried out with members of the UNESCO Chair of the Salesian Polytechnic University Campus the Girón.
