Abstract


The paper analyzes the most current applications for visually impaired people, in order to understand and identify the problems they have, with the idea of creating an application for such a device that includes all the useful functions and reduces the existing disadvantages. The applications presented were tested both day and night, using 2 different phones, both with Android and iOS operating systems. The main needs of a visually impaired person were monitored as follows: following a route to a supermarket; identification of the main food products, pharmaceuticals, money. During the test, several objects were analyzed, but we focused on details that cannot be easily identified by touch. To reduce the acquisition costs of the assistive device and make it accessible to a larger number of users, we modeled and designed a system that can be attached to an already existing white cane. This system can be easily assembled and disassembled, allowing the user to fold the cane, which is then easy to carry in a backpack or even in a pocket.
