Gestus Sound Library: Looping the Robot
The following example has been added to my “SC Sound Library” as another synth that can be assigned to a fiducial object or a blob in order to enrich musical experimentation. Here is the code:

SuperColliderAU - Audio Unit Wrapper
I have managed to interconnect SC and Logic through SuperColliderAU.
“SuperColliderAU is an AudioUnit wrapper that allows using SuperCollider servers inside AudioUnits hosts on MacOSX. The embedded server may be controlled over OSC as usual. In addition, it may be packed with a synth definition and a configuration file that defines its parameters”. (SuperColliderAu Help File)

Implementation of the GESTUIO Subclasses
Working in my Abstract_GESTUIO class. At the moment It has two subclasses: the GESTUIO_2Dobj for tracking fiducials and the GESTUIO_2Dcur for blob detection.It shows how to use TUIO from Reactivision for a basic type of installation. It works solely from data received from Reactivision (v1.4) and Community Core Vision (v2.4). Run on MAC OS Snow Leopard.
On each subclass i have use a different...
Implementing an Abstract_GESTUIO Class
Working on my Gestus project. Today we have managed to implement a new class, called Abstract_GESTUIO class, as well as to solve the problem found on the GESTUIO_Object class and GESTUIO_Blob class we had before.
Introduction: All blobs or objects are sent as OSC messages from either ReacTIVision or Community Core Vision, using the TUIO Protocol. SuperCollider receives these messages through an...

Working on Xcode Workflow Tutorial
Finished working on Xcode Workflow Tutorial. This short tutorial shows how to create an Xcode project for a Cocoa application called Hello that prints “Hello, World!” inside a window. Its primary purpose is to show you the workflow that you’ll use for creating your own software with Xcode—from creating a project to getting an application to run. You’ll also see how to fix compile-time...

Constructing the first set of Gestus Fiducials
I have just finished constructing my first set of fiducial objects. Each object has a printed symbol on each side. Four objects, eight individual symbols. Here is a picture:
My approach on how to make my fiducial objects with no much cost, has been proven correct. Objects seem solid and fiducial symbols are easy to detect. More on this on my next post.

Dual camera test: blob & object detection.
Test Case: Blob and object detection, using two cameras.
Scenario: Having one camera tracking all blob detection from open-handed gestures in space, while the second one tracking all object activity on a multitouch surface.
Cameras: Camera1 (Creative Usb WebCam) detects all blob activity using the TUIO_Simple_Demo class with data sent from CCV v1.2 to SC. Camera2 (on board Macbook Pro ) detects...
TUIO Simple Object Demo Class in SC
I have created a class named TUIO_Simple_Object_Demo. This class is based to TUIO_Simple_Demo blob detection class developed on 11/12/09. Aiming towards an object/fiducial detection, by tracking data through the Reactivision v1.4 software, this time i have tested the /tuio/2Dobj protocol set profile. It worked fine as the /tuio/2Dcur profile does.

Two more parameterers on TUIO 2Dcur profile set.

Testing SETO and TUIO
How does SETO work now? Can you give some description, screenshots, examples?
In any case we’ll need to have a look at TUIO with tbeta together because it is certain that you will need to master it at the protocol level in order to develop more freely for it.

FTIR and LP : Unable to recognise fiducials.
Studying the NUIʼs Multitouch Technologies book, i have found that neither FTIR or LLP does not track objects or fiducials There might be a possible solution for fiducial recognition in FTIR and LLP by increasing the fiducialʼs pressure on the surface. More research is needed.
