All the features and the science behind each one
Real time GIF analysis
Epilepsy Blocker scans your screen in real time and blocks dangerous content, kinda like an AdBlocker blocks ads. It uses a specialized algorithm based on the work of leading scientists in photosensitive epilepsy, like Prof. Graham Harding, as well as the well-established guidelines of Ofcom (Source)
Blue screen filter
Epilepsy Blocker can optionally place you under a general umbrella of protection by applying a blue tint on your browser, similar to how blue sunglasses would. Studies have shown that it can help people with photosensitive epilepsy (Source)
Break & Hydration Reminders
You can optionally set up reccuring reminders, so you won't forget to take breaks and stay hydrated, things that 'The Epilepsy Foundation' recommends people with photosensitive epilepsy to do while using a computer or phone (Source)
Automatic blocking of dangerous videos (Coming soon)
We are working on supporting large videos files as well. That would mean videos on YouTube etc
Here's what some happy customers have to say 💜
I want to give a huge shout out to @alexsideris_— Indie Gamer Chick (@IndieGamerChick) 4 April 2019
He developed the Epilepsy Blocker extension for Chrome and Firefox. It disables flashing GIFs, the ones that can give me a seizure.
I'm triggered by ads far more than by video games. Probably because they're unexpected.
Trust me you have made mine! I have lived with photosensitive epilepsy for 37 years. I dread holidays as I have to get hubby to check every message & remove all flashing gifs sent. This will give me my independence back! That means everything to me!— Raw Ability Life (@RawAbilityLife) 31 March 2019
Thank you for doing this. Being online is a big risk for those of us with PSE, and some extensions that are supposed to help with this are useless, most especially on Tumblr. I like using GIFs and some are quite funny, but too often people don't tag the especially flashy ones.— One stitch at a time 👩🏼🎨 (@Chaosfay) 31 March 2019
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
Browser extensions are programs that can be installed into Chrome or Firefox 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
Both! It works for desktop devices and on Android devices. For Android, you will have to download an extra app, which is free
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
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
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
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
Yes, you can use it on multiple devices simultaniously, meaning you can use it on your computer or laptop as well as your mobile phone or tablet
Yes, the extension is available for both Chrome and Firefox
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..
I want to be here for the next 10 years, not the next 10 months
