"Phi is not Beta"
This site, developed by Filip J. Pizlo, requires a Java 1.1 browser, such as Netscape 4.06 or later and Internet Explorer 4.0 or later. It serves as a complement to the "Phi is not Beta" Mini Review (cited below), and offers several tools that will show you Magni-phi, a greatly enhanced version of the phi-phenomenon, and the original Phi as discovered by Max Wertheimer in 1912. A number of options are provided below, including a Web-enhanced presentation intended to summarize the Mini Review.
Phi is not Beta, or why Wertheimer's discovery launched the Gestalt revolution. This is a Web-enhanced slide-show which contains the original text of the talk given by Steinman, Pizlo & Pizlo at ARVO on Monday, May 1, 2000 @ 15:45 GMT. It also includes a guided version of the ARVO Demo applet, which explains each of the views in depth.
This page is recommended for those who are seeing Magni-phi for the first time.
ARVO Demo was displayed during the talk given at ARVO in 2000. This demo provides a series of pre-configured menu options that demonstrate the robustness of Magni-phi, and compare it to Phi and Beta.
Custom Magni-phi is user-configurable. Magni-phi depends primarily on delay parameters, so it is best to leave them alone until the other options have been explored.
Custom Simpli-phi demonstrates Wertheimer's Phi, which is much less vivid.
