What Do Users Say About Psykinematix?
I have recommended Psykinematix to students because it is a quality fast-track solution to experiment design and development.Max Farrell-Whelan, Macquarie University
Psykinematix is an excellent tool for the rapid and accurate development of psychophysical testing. It allows for the swift conversion of ideas into experiments.
Ben Thompson, University of Auckland
The free demo version of Psykinematix is also a great learning tool to introduce visual perception and illustrate psychophysical concepts to students. To learn more about the use of Psykinematix in clinical research, check out our VSJ 2009 paper: "Psykinematix: A New Psychophysical Tool for Investigating Visual Impairment due to Neural Dysfunctions".
MONTREAL, Canada —May 3, 2011—KyberVision today unveiled Psykinematix 1.3 with 14 new features worth noting (latest update v1.3.2 compatible with Mac OS X 10.7 Lion):
- Support for "Frame Sequential Stereoscopic" presentation (i.e.based on stereo pairs presented sequentially at a high frame rate, typically 120 Hz, using for example a 3D graphics card such as the NVIDIA Quadro FX 4800 in combination with shutter glasses like the REALD StereoGraphics CrystalEyes)
- Support for fORP device in keyboard mode as input device and scanner trigger,
- Support for Spyder 3 colorimeter from DataColor
- Sampled-Shape Stimuli (SSS) as Multi-Element category (eg to create Gabor-sampled patterns, path stimulus, etc)
- Support for Shape Stimuli in RDK, MEF and SSS Multi-Element stimuli
- Conversion of Multimedia images: grey conversion, RMS normalization, and contrast scaling
