Not A Patent

After the guy on Twitter got a seizure as a result of an attack, I've been wondering if such things could be prevented. My idea is to have all video be passed through a filter that can detect seizure inducing content (such as by using the Harding test), and stream something else instead if it fails at any point. It would be based around holding a buffer of the stream and performing calculations on that buffer (would probably technically have two buffer, one for content that was passed and the second for content that is being streamed that is yet to be passed), if it passes then the next frame in queue is streamed, otherwise it streams a different frame (maybe just a repeat of the last one to pass) that will cause whatever is in the buffer to pass instead. It would probably have to have a lower threshold than the Harding test in order to ensure it's safe. I think the best way to implement this would be as an embedded system to create a piece of hardware with the stand inputs and outputs for visual and maybe audio as well. That way it can be integrated into any device that uses standard I/O without the device knowing anything is going on, it can use specialized hardware to be extremely fast, and it can be sold as a cheap dongle to people with photosensitive epilepsy. A free software version should also be made, though that may require some more technical expertise from the user to know how to set up. Ideally the software version could be integrated into operating systems so it can be toggled as an accessibility feature like sticky keys and whatnot. Anyway, just throwing this out there as I think it's a good idea and so far I haven't been able to find anything like it, and maybe someone with the technical ability can build a working a prototype or at least an actual patent so this sort of thing can actually be made.
