Did you just notice that?
Epilepsy Blocker analyzed the GIF below in real time and found that it's safe for people with photosensitive epilepsy to view
This is dangerous GIF slowed down
Why should I add this?
The internet can be a dangerous place for people with photosensitive epilepsy. There are cases where flashing GIFs have triggered epileptic seizures (Source)
There even more extreme cases where flashing media content has sent hundreds of people to the hospital with seizures (Source)
How does this work?
Epilepsy Blocker uses a specialized algorithm based on the work of leading scientists in photosensitive epilepsy, like Dr. Harding from Cambridge University and Professor Binnie from King's College London. It's a chrome extension that blocks dangerous, flashing GIFs as you are browsing the web
For about 3% of people with epilepsy, or else 2 million people worldwide, exposure to flashing lights at certain intensities or to certain visual patterns can trigger seizures. This condition is known as photosensitive epilepsy
What is a chrome extension?
Google Chrome extensions are programs that can be installed into Chrome in order to change the browser's functionality. They are very easy to install and after installation, they work seamlesly in the background without us having to do anything
What makes a GIF dangerous?
In general, there are three things that can make media content dangerous
1) Large enough flashes with great enough contrast at specific frequencies
2) Frame transitions including saturated reds
3) Some geometrical patterns, such as striped patterns
What is the algorithm behind this?
The algorithm is based on the work of leading scientists in photosensitive epilepsy, like Dr. Harding from Cambridge University and Professor Binnie from King's College London. It detects flashes in content and will soon detect red transitions and dangerous patterns also
I am 100% safe when using this?
No one can be sure about all the variables that trigger a seizure. This is a very sensitive matter, and I take it very-very seriously, so I would never guarantee that. However, I have followed the most established guidelines worldwide for minimizing the risk of having a seizure
Does it work on every single website?
It works on nearly all websites, for example you will have no problem while browsing around the web, like on Wikipedia and googling around 'random' websites. However, some websites store GIFs as videos, so it is a little difficult to detect. I am constantly working on supporting every single website
Public Roadmap 📝
Analyze GIFs for dangerous flashes
Make it work perfectly for general browsing (eg. Wikipedia, googling around visiting random websites)
Make it work perfectly for Facebook, Twitter
Make it work perfectly for 9GAG, Reddit (very soon)
Analyze GIFs for dangerous red transitions (soon)
Analyze GIFs for dangerous striped patterns (soon)
Keep yourself and your loved ones safe for $1 a day ($30/mo)
For beta testers, at the price of two cups of coffee per month ($10/mo)
Why isn't this free?
Unfortunately, Epilepsy Blocker costs money to run, monthly server costs can skyrocket when analyzing hundreds or even thousands of GIFs.
(eg. A single 600x600 GIF with 200 frames has 200 frames x 600 pixels x 600 pixels = 72 million pixels to analyze)
I'm a real human, not some huge corporation with a limitless budget. Unless I charge for money, this project will shut down very soon.
By paying for Epilepsy Blocker not only are you ensuring that it will keep running forever, but you are even enabling me to work full time on this project and make it even better, I have lots of ideas..
Last but not least, by paying, you are helping me achieve my dream, that of earning a living by doing something that is meaningful and that I love
