"Infinito" is an art piece by Juan Pablo Colasso where spatial dimensions are made explicit through the spectator's interaction.

In this installation, the spectator enters a dark room just by himself, where he is directed to a central alley. Since the spectator has no prior instructions but to enter alone, at this point he or she enters an exploratory mode and does the only thing available, which is to walk forward.

As he walks, the central projection starts to change, going though different spatial dimensions beginning at the biggest dimension known to mankind, and travels until reaches our universe, our galaxy, our Solar System, then Earth, human size, and then starts to delve into even smaller dimension until reaching the sub atomic realm.

The system was created using Openframeworks to process the input of three PS3Eye cameras. All image acquisition was made using infrared lighting and proper filtering. Then we also used Unity3D to process the user tracking data and to control camera movements. Unity 3D was also used to render the final projection, and to send scene object's information to an audio-synthesizing application developed in Max.


3D Environment

The 3D environment was modeled and textured using 3D Studio Max, All textures and particles were generated based on photos of naturally generated fractal kind forms as corals, pollen, plants and animals,



“Infinito” soundtrack is generated in real time with a software capable to react to the animations of the screen, the movements of the spectator and the acoustic characteristics of the room where is exposed.

With the idea of composing reactive music for micro and macro worlds, covering the entire spectrum of mass and energy known, we decided to use a wide palette of sounds that goes from the simple to the complex, selecting a set of low and high frequencies oscillators that primarily use sine waves and pink noise as playback source. The range of frequencies used in the composition is chosen from the acoustic analysis of the room.

Figure 1: Table with the room measurement values and selection of notes and frequencies suitable for the composition.

Another special feature of this work is that most of the sound synthesis does not occur in the digital field but in the acoustic field. The movement of sounds in space and the interaction of the waves with the room are fundamental aspects of the composition.


Durante los 45 dias de instalación se registraron 2559 diferentes accesos, con un total de 4323 minutos de experiencias.

Cada usuario fue trackeado durante todo su recorrido con el proposito de conocer los comportamientos y preferencias. Como se esperaba, la mayoria de los usuarios se sienten mas comodos dentro de los lugares conocidos, entre la tierra y la piel.
