Active Spaces Project is an interactive art work in a mixed reality environment that aims to browsing and interaction with digital and real space. Specifically, the present dissertation attempts to appoint the connection between the real and digital space through research and experimentation in Augmented Reality (AR) as digital multimedia, and the living experience through the ambient interactions created by the combination of these two, in the new space. The purpose of the project is to reveal those we do not see in space and at their combined tangible experience using an application of Augmented Reality. The application will display virtual 3D animated graphics with sound, in the physical structured space, placing the viewer as an active co-creator of the project experience. Space is no longer empty, but full of waves, particles, structures and forms that pulsate, flow and oscillate, approaching the dimension of atmosphere and space. In the form of light, the structures are revealed and absorbed in a game of constant confrontation with time and space. Sounds, masses, movements and proportions, create an abstract rhythmic code of communication that focuses on stimulating the viewer's senses.
