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 —June 21, 2012—KyberVision today unveiled Psykinematix 1.4 which brings 15 new features, 40 improvements, and 13 bugs fixed, the most worth noting being:
- Support for OS X 10.8 (Mountain Lion),
- Graph Properties palette in Plotter panel to better customize the appearance of the results plots and with user-defined styles,
- Custom bootstrapped fitting of measurements as function of independent variables (with error bars, goodness of fit reported),
- Built-in functions for fitting measurements as function of independent variables (Linear, CSF, VSM, TvC),
- Support for spatial dithering to improve luminance and color resolution (up to 14 bits per component),
- Ishihara Stimuli category (with customizable target and ground appearance),
- Support for imported images as parameters in Custom Stimulus through the "Image File" unit (allows advanced image processing!),
- Addition of mag(X) and phase(X) functions in Custom Stimulus,
- Better support for Japanese, Simplified and Traditional Chinese characters in Text Multimedia stimuli,
- Support for stereo format in RDK stimuli,
- Full support for spatial nAFC for MEF and SSS stimuli,
- Addition of Weber and Michelson contrast specifications to image Multimedia events,
- Support for Mouse-Driven stimulus coordinates (ie move your stimuli in real-time using your mouse!),
- Support for Spyder 4 colorimeter from DataColor,
- User Guide as an iBooks Textbook for iPad (unzip and drag in the books section of the iTunes software and sync with your iPad).
