A Secondary Aid that Helps to Create Cognitive Maps for Visual Impaired Persons

Abstract

Mautly Pathfinder is a system designed to obtain images of the surrounding world presented to a blind person by any video camera and to manage those images to obtain only the significant information for the user such as the shape, size, position and relative movements of possible hazards. This information is transmitted to the user by a vibrating matrix located on the abdominal region of the body. Furthermore, pulses in which frequency vanes depending on distance between such hazards and the user are sent to a vibrating interface located on the chest of the impaired person. The purpose is to give enough information to the user to create a cognitive map of the local environment. The system is designed to be wearable and to work at real time, which means that the data processing and the results delivering of such information are done almost instantly.
