We developed an augmented reality application to know the history through the posters that are located in front of the historical buildings of the city. Each poster has information on the most relevant aspects, audio and photos of them. In this way, in a self-guided way, you can tour the city virtually and learn about the history of Esperanza ¨First Organized Agricultural Colony of the Country¨, through the buildings that are witnesses and emblem of the cultural, social and economic life of the city. . (Only for Android).
