In addition to vision-related iOS Apps for iPhone, iPod touch and iPad, we developed the Psykinematix software, our Mac OS X flagship product in the field of Visual Psychophysics and Cognitive Neuroscience. KyberVision - Innovations in Vision Sciences. KyberVision Japan LLC. Psykinematix is an advanced OpenGL-based Software Package for Visual Psychophysics running on macOS. Easy to use, subject-friendly, powerful and reliable, Psykinematix allows you to run standard psychophysical protocols, present complex stimuli, collect subject's responses,.

What better way to begin a New Year..

December 3, 2009

Dear Vision Scientist,

We hope you had a great start to the academic year. So what better way to carry on than by discovering a few new tools to improve your research productivity?

First, we are pleased to announce the availability of Psykinematix Version 1.1, our Mac OSX OpenGL-based software dedicated to visual psychophysics. This second public release contains many bug fixes, improvements, new features, new tutorials, and an updated documentation. This new version is fully compatible with Mac OS X 10.4 ('Tiger'), 10.5 ('Leopard') and the just-released 10.6 ('Snow Leopard'), and still runs on older PowerPC-based and newer Intel-based Macintosh computers. With this release we are also introducing:

• a new entry price: Psykinematix is even more affordable now that there is a C$300 Student Licenseavailable to individual researchers & students.


• a Forum available to all registered Psykinematix users who wish to share their experiences with the Psykinematix community.


• the full documentation available online.


• our invited paper presented at the 2009 Winter Meeting of the Vision Society of Japan:
  William H.A. Beaudot (2009) Psykinematix: a new psychophysical tool for investigating visual impairment due to neural dysfunctions. Vision: the Journal of the Vision Society of Japan, 21(1):19–32

Second, we realized how powerful the iPhone and iPod touch mobile devices are, and we have implemented some of the Psykinematix capabilities on this new computing platform. We already have four inexpensive 'Apps' available at the iTunes AppStore that we think could be of great interest to you:

Thank You and Best Wishes for A Wonderful Holiday Season!

Visual psychophysics teaching tool (was Psykinematix).

Psykinematix GPU (was Psykinematix) is a new OpenGL-based software package dedicated to visual psychophysics running on Macintosh computers only. Psykinematix GPU consists in a unique stand-alone application that does not require any programming skill to create and run complex experiments. Easy to use, subject-friendly, powerful and reliable, Psykinematix GPU runs standard psychophysical protocols, generates and presents complex stimuli, collects subject's responses, and analyzes results on the fly. Psykinematix GPU is also a great learning tool to introduce visual perception and to illustrate psychophysical concepts to students.

• Addition of 'bessj1' and 'bessjn' Bessel functions for Custom stimulus
• Support for 'rnd' and 'irand' functions in shader-based Custom Stimuli
• Support for 'time' variable directly in custom expression (also works for OpenGL Preview or movie export)
• Improvement of Graphing Math Palette to specify temporal properties of stimuli
• Support for spatial jitter direction in SSS stimuli (x-, y- and isotropic in addition of xy-)
• Improved generation of non-overlapping heterogeneous SSS stimuli elements with warning in case the overlapping constraint is too strong
• Addition of minimum/maximum abort criterion based on a number of consecutive incorrect responses in Staircase properties panel
• Support for custom catch values in Staircase properties panel (multiple values separated with )
• Support for Standard/Test randomization for MOCS and Bayesian Methods
• Addition of a separate ISI parameters to insert between the Standard/Test randomization in Yes/No procedure
• Addition of PAUSETRIALS, PAUSETIME, PAUSEDURATION and PAUSEMSG system variables to control pauses at regular intervals
• Support for string variable in Association composing
• Better estimation of calibration completion levels (based on the selected chromatic mode)
• Addition of NetStation Drift Correction and Sync Timing options to troubleshoot communication timing

User Interface Improvements

• Events' property panel can now be opened by simply clicking the events' icon
• Psykinematix files can be opened by directly double-clicking them in the Finder (*.epkmx, *.lpkmx, *.dpkmx)
• Support for undo/redo operations in Designer panel
• Addition of a contextual menu to events in Designer panel
• Support for undo/redo operations when editing expression for 'Custom' stimuli
