Debian Science Psychophysics packages

libfreenect is a cross-platform library that provides the necessary interfaces to activate, initialize, and communicate data with the Kinect hardware. Currently, the library supports access to RGB and depth video streams, motors, accelerometer and LED and provide binding in different languages (C++, Python...)

This library is the low level component of the OpenKinect project which is an open community of people interested in making use of the Xbox Kinect hardware with PCs and other devices.

This is the development package containing the libraries and header for software development with libfreenect.

Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab and GNU/Octave functions for vision research. It makes it easy to synthesize and show accurately controlled visual and auditory stimuli and interact with the observer.

The Psychophysics Toolbox interfaces between Matlab or Octave and the computer hardware. The Psychtoolbox's core routines provide access to the display frame buffer and color lookup table, allow synchronization with the vertical retrace, support millisecond timing, allow access to OpenGL commands, and facilitate the collection of observer responses. Ancillary routines support common needs like color space transformations and the QUEST threshold seeking algorithm.

See also http://www.psychtoolbox.org/UsingPsychtoolboxOnUbuntu for additional information about systems tune-up and initial configuration.

This package contains bindings for Octave.

PsychoPy fournit un environnement de création de stimuli psychologiques en utilisant le langage Python. Il combine la puissance graphique d'OpenGL avec la facilité de la syntaxe Python pour donner à la psychophysique un paquet de contrôle et présentation simple et libre des stimuli.

Le but est de fournir, pour le scientifique débordé, des outils pour contrôler le temps et le fenêtrage, ainsi qu'un ensemble simple de stimuli et de méthodes pré-empaquetés. PsychoPy fournit :

 – un EDI graphique dans un langage de script puissant (Python) ;
 – un constructeur d’interface graphique pour un développement rapide de
   séquences de stimulation ;
 – une utilisation de l’accélération matérielle (OpenGL) ;
 – une intégration avec Spectrascan PR650 pour une calibration facilitée
   des moniteurs ;
 – des routines simples pour des méthodes expérimentales de stimuli
   graduels ou constants, mais aussi par ajustement de courbes ou
   auto-amorçage ;
 – des interfaces graphiques simples (ou complexes) à l’aide de wxPython ;
 – des interfaces simples pour des manettes de jeu, des souris, des cartes
   sons, etc., à l’aide de PyGame ;
 – une lecture de vidéo (MPG, DivX, AVI, QuickTime, etc.) comme stimulus.

Ce métapaquet installe les paquets de Debian qui peuvent être utiles aux scientifiques intéressés dans la recherche en neurosciences cognitives. Cela comprend le processus de recherche complet, de la conduite d’expériences de psychophysique à la visualisation et composition typographique de résultats scientifiques.

La sélection de paquets vise les applications de technique d’analyse. Les développeurs de méthodes peuvent consulter les métapaquets science-statistics, science-imageanalysis, science-numericalcomputation, med-imaging et med-imaging-dev pour divers logiciels supplémentaires qui pourraient être utiles dans la recherche en neurosciences cognitives.

Stimulus counter-balance is important for many experimental designs. This command-line software creates De Bruijn cycles, which are pseudo-random sequences with arbitrary levels of counterbalance. "Path-guided" de Bruijn cycles may also be created. These sequences encode a hypothesized neural modulation at specified temporal frequencies, and have enhanced detection power for BOLD fMRI experiments.

PEBL (Psychology Experiment Building Language) is a system designed for creating psychology and neuroscience experiments and tests. It offers a simple programming language tailor-made for creating and conducting many standard experiments.

The Vision Egg is a programming library that uses standard, inexpensive computer graphics cards to produce visual stimuli for vision research experiments.

Nrec , developed by Friedemann Bunjes and Jan Gukelberger at the Neurology of Tübingen University, is a package for stimulation, data acquisition and experiment control in the flavour of cognitive fMRI research, which has been expanded to include flexible biosignal acquisition and sensory stimulation. It produces Matlab-readable files and generally puts an emphasis on standards like using the comedi Linux data acquisition library, OpenGL, XML parameter file format and hdf5 data storage files format.

Psychlops is a free C++ library to offer the easy way to develop a demonstration of various types of visual stimulus used in the Vision science.

Binary builds are available only for OS X and Windows. Sources available from sf's SVN: http://sourceforge.jp/projects/psychlops/svn/view/cpp/

Tscope is a C/C++ experiment programming library for cognitive scientists. It provides functions for graphics, sound, timing, randomization and response registration.
