QSG-RU Quad Soundscape Generator- Río Uruguay - 2009-2013, Maar (Marco) Colasso.

A realtime soundscape generator for tabletop surfaces. Perceptual classifications of sound and environment are being used to get an holistic management of the sound by the user, being complemented with adaptative mapping techniques commanded by the logic engine. In this way we want to control the whole system away from the rational analysis used daily in the creation and manipulation of sound.

##2. SOFTWARE INSTALLATION

This Application is Cross-platform. In order to run this code, you need 3 programs and some externals.

Tracker.

Use Reactivision or a TUIO compatible software to track fiducials and objects.

SOFTWARE

This is a project programmed 100% based on free and multi-platform software.

The application requires three programs to run simultaneously.

1- Reactivision: It is the tracker responsible for recognizing tangible objects on the surface, sending information via OSC.

2- Gesture recognition, logic, and visual feedback are programmed in Processing. This communicates with Pure Data through OSC.

3- The application responsible for sound is programmed in Pure Data.

How can I use this application?

The procedure is quite simple,

1- First, we must download the code from GitHub.

2- Then we must open Processing and run the sketch _01_qsgVisuales.pde

2- Open Reactivision. Calibrate. If you haven't built a table, you can try with TuioSimulator.

3- Open in Pure Data Extended 0_qsgRU.pd

The controller consists of a low-budget multitouch table that can recognize the shape, orientation, and position of so-called tangible objects on the table.

There are two types of tangible objects:

1- The first are made of acrylic, and on the bottom, they have fiducials, which is a unique code that is recognized when placed on the surface.

2- The others are simple wooden objects, recognized as "blobs."

The table is built using a technique called diffuse backlighting, basically consisting of a cube made of wood, containing infrared LEDs inside capable of illuminating the surface as evenly as possible. A diffuser material is placed on the surface, composed of two layers of glass, a normal glass of 3 millimeters, a diffuser material, and a sandblasted glass of 4 millimeters. When an object touches the surface, it reflects more light than the diffuser and the objects in its background. The light is reflected and detected by a camera with an infrared filter, so it is capable of capturing only infrared light, finally, the information is digitized to be analyzed by a tracker (Reactivision).

For more information regarding the construction of this type of device, you can visit the NUI-Group forums and download the package of files that gathers the most relevant information for the construction of this table.
