Visual Testing Software – VPixx Program

VPixx Program

The VPixx Program, a result of over twenty years of experience in vision science programming, is the perfect tool to generate and present frame-synchronized animated stimuli within the context of a testing paradigm. VPixx supplies you with powerful features to easily manage complex dynamic visual and audio stimuli and experimental designs, all within a single user-friendly Mac OS X application. The VPixx Program fully supports the DATAPixx, VIEWPixx, PROPixx and RESPONSEPixx hardware products, offering you stereo audio stimulation, subject response time measurement, analog data acquisition, and triggering of external equipment, all with microsecond-precise synchronization to video refresh.

DATAPixx Toolbox

Toolbox_MATLAB

The DATAPixx toolbox for MATLAB is now delivered as part of a standard Psychtoolbox download. The PsychToolbox imaging pipeline has been updated by Mario Kleiner to take advantage of the high bit depth of the DATAPixx. The library supports all of the video processing and data I/O subsystems of the DATAPixx hardware toolbox, combining the simplicity of MATLAB with the microsecond precision of the DATAPixx.

Toolbox_Octave

Octave is a free open-source alternative to MATLAB. The DATAPixx toolbox for Octave is now delivered as part of a standard PsychToolbox download. The PsychToolbox imaging pipeline has been updated by Mario Kleiner to take advantage of the high bit depth of the DATAPixx. The library supports all of the video processing and data I/O subsystems of the DATAPixx hardware toolbox, combining the simplicity and freedom of Octave with the microsecond precision of the DATAPixx.

Toolbox_python

pypixxlib uses the object-oriented approach and strengths of Python. With pypixxlib, you can get information from and to your devices, while using your preferred python packages for stimulus generation. pypixxlib converts your physical device into python objects with attributes matching the subsystems included in VPixx devices. This guarantees everything you attempt is executed on the subsystem you intended. We also offer a functional approach with the versatility of Python; pypixxlib includes a wrapper for our ANSI C API. Complete with full documentation and demos, pypixxlib is easy to use.

Toolbox_C_API

For those who prefer the lowest-level interface possible, we provide a low-level ANSI C API. The API even includes a detailed register map for the DATAPixx. The API has been tested under Windows XP, Windows 7, Windows 8, Mac OS X, and various Ubuntu and Debian distributions.

Toolbox_PLDAPS

PLDAPS: a hardware architecture and software toolbox for neurophysiology requiring complex visual stimuli and online behavioral control.
