Localização de deficientes visuais em ambientes fechados e reconhecimento de produtos

Abstract

One of the problems faced by the visually impaired is the location of objects in an unfamiliar environment. Find a product in a store without assistance is almost impossible for a person with low vision. Therefore, in this research we developed a system to provide the location of products in the supermarket aisles and then allow reading the bar code or NFC tag on the product or on the shelf .To select from the options location or identification, the screen cell was divided into two parts such that the blind or visually impaired persons may choose between them. Hence, in this study used a smartphone with Android operating system. The system was developed using the MIT App Inventor 2. This interface is a web application with open source developed by Google and maintained by the Massachusetts Institute of Technology (MIT). The interface is divided into two parts, one devoted to the design and implementation for another logic. The program is based on the Scheme language, Google voice ID and bar code reader. The device was tested indoors simulating aisles and shelves of a supermarket measuring the time required to find and identify five products. The adoption by store and supermarket system developed for this research, facilitating the location and identification of products, should contribute to the independence and quality of life for people with visual limitations
