KyberVision Unveils Psykinematix 1.5, GPU and Bits#/Display++ Editions v2.0

Psykinematix 2.0: The world most advanced software solution for visual psychophysics!

SENDAI, Japan — August 3rd, 2015 —KyberVision Japan LLC unveiled today several major updates of Psykinematix, its Mac OSX OpenGL-based software dedicated to visual psychophysics.

Psykinematix v1.5 Standard Edition is an incremental free update with many bug fixes, improvements, and new features. This version remains fully compatible with Mac OS X 10.4 ("Tiger") to Mac OSX 10.10 ("Yosemite"), and still runs on both older PowerPC-based and newer Intel-based Macintosh computers.

Psykinematix v2.0 GPU Edition takes advantages of the computation power (GPU Computing) available in modern graphics cards. Their computation power is harvested without any additional work from the end-user: built-in and custom stimuli can be generated on the fly and in real-time hence minimizing the amount of required video RAM and freeing the CPU for more important tasks.

Psykinematix v2.0 Bits#/Display++ Edition is the result from a fruitful collaboration between Cambridge Research Systems (UK), Namoto Trading (Japan) and KyberVision Japan LLC: it brings support for the Bits# Stimulus Processor, Display++ LCD Monitor and accessories from Cambridge Research Systems which specializes in bringing to market the best hardware solutions for vision science. Psykinematix v2.0 is fully compatible with Mac OS X 10.6 ("Snow Leopard") to Mac OSX 10.10 ("Yosemite"), and runs only on Intel-based Macintosh computers.

What's New with Versions 1.5 and 2.0?
  • Support for OS X 10.9 (Mavericks) and OS X 10.10 (Yosemite)
  • Addition of Backup & Restore options in File menu
  • Support for 11.6 bits monochromatic mode through Bit-Stealing
  • Support for Noisy-Bit technique (stochastic dithering) to provide quasi-continuous luminance resolution (based on Allard & Faubert 2008)
  • Addition of "Targeted Chromatic Mode" in Gamma calibration panel
  • Report R2 value for Gamma correction
  • Support for Catch trial proportion in Staircase method
  • Addition of optional Pause between repeats in Conditions Method
  • Standard/Test intervals randomization option in Yes/No procedure
  • Improved speed and memory usage when generating time-varying stimuli
  • Addition of pnoise(X,Y) function to generate Perlin noise in Custom Stimuli, log2(), clip(), step() and hsmoothstep() in mathematical expressions
  • Addition of a "Hole Size" parameter in zone specification for RDK stimuli
  • Addition of "Asyn/Syn" lifetime mode in RDK stimuli
  • Support for time-varying elements in RDK stimuli and "Asyn/Syn" dynamics mode

  • Support for multimedia image stimulus in MEF and SSS stimuli
  • Support for time-varying grid size in MEF stimuli
  • Support for time-varying alpha for Text Multimedia stimuli
  • Support for custom image as target and square shape for ground in Ishihara stimuli
  • And many other improvements...
Specific to Psykinematix GPU Edition:
  • Support for GPU-based preview and run-time rendering for custom, grating and checkerboard stimuli
