Photosensitive Epilepsy Analysis Tool


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. The evaluation used by PEAT is based on an analysis engine developed specifically for web and computer applications.

Learn more about what an epileptic seizure is, common types of seizures and how these can be induced by computer screens or content being rendered.

  • Challenge 1 is to create a piece of software that can be installed in a display (or box connected to a display) that will monitor the signal coming in to the display, detect visual events that are known to trigger a seizure, and alter the signal to remove that stimulus.
  • Challenge 2 is to create a pair of glasses that can monitor the environment for seizure inducing visual events, detect them, and then modify what the user sees in order to reduce or eliminate the seizure inducing event.

The Trace Center created a Photosensitive Epilepsy Analysis Tool (PEAT) that can analyze web and software to detect visual events that are known to cause seizures. This prize is for the creation of a “clean room” open source version of the tool.
