The Trace R&D Center was originally formed in 1971 to address the communication needs of nonspeaking people with severe disabilities.
To make it practical to use the new W3C Web Content Accessibility Guidelines (WCAG), the Trace Center, in conjunction with Dr. Graham Harding and Cambridge Research Systems, developed a new free web tool for evaluating Web content and software.
The Trace Center’s Photosensitive Epilepsy Analysis Tool (PEAT) is a free, downloadable resource for developers to identify seizure risks in their web content and software.
PEAT can help authors determine whether animations or videos in their content are likely to cause seizures. Not all content needs to be evaluated by PEAT, but content that contains video or animation should be evaluated, especially if that content contains flashing or rapid transitions between light and dark background colors.
This tool can test content for conformance with the photosensitive seizure prevention rules in both the Web Content Accessibility Guidelines and the proposed new 508 and 255 revised guidelines of the US Access Board. Software Can be installed from: https://trace.umd.edu/peat/
