This document presents the experimentation, development and results of testing conducted on a computer application designed for visually impaired people. The interactive system aims to promote some places in the State of Aguascalientes, Mexico, and improve the memory of blind users. The purpose of this article is to describe the construction of the system and the testing conducted to measure the degree of interactivity with blind people. Creating interactivity-focused applications is important since it can improve the degree of technology usage (mobile devices) of people with disabilities. To assess the quality of this type of software, the specifications they should meet need to be established. They involve big screens, adapted keyboards and ergonomics  and depend on the type of disability being addressed. Therefore, they should be characterized to determine how to develop them and assess their quality with the degree of interaction obtained. The main contribution of this work is presenting the results of the degree of interactivity of the system when used by blind people and detailing part of the Team Software Process (TSP) defined by Watts Humphrey and adopted for developing the application .
