from the physical-assault-in-a-virtual-world dept.

Newsweek journalist Kurt Eichenwald, who is known to be suffering from epilepsy, reported on twitter that someone tweeted him a seizure-inducing image. This is not the first time it happened, but this attempt was (apparently) successful in triggering a seizure.

This might be the first physical attack on a person perpetrated via the internet. A sad point in history, in my view.

Links: coverage from Ars Technica, Eichenwald's Twitter feed. I'm not linking to the offending image - you're big enough to find it on your own and apparently it is quite horrible even for people who do not suffer from epilepsy.

Eichenwald has tweeted that he is involving law enforcement.

Any ideas on how hard it would be to filter out seizure-inducing media (make it click-to-view/play)?

    I suppose something that checks contrast between frames would catch some.

    Short videos could be much harder to check than GIFs.

    Its just cpu time. And with hardware assisted decode probably not very expensive.

    I think the hardest part, from a usuability perspective, would be having to wait for the media to completely download because you can't say if its clean or not until you've checked every last frame. Even animated gifs can be multiple megabytes in size nowadays.

      There's no need to download everything. Could just check the buffer and stop playing or turn on a filter (e.g a "deflicker"/average filter- like the deinterlace stuff) if something seems like it might cause a problem. Most video streams get buffered anyway.

      Maybe someone could create such a plugin. Problem is it won't catch everything for everyone. Maybe some tuning depending on the person. Is it common for fits to also be triggered if it's alternating blue/red of the same brightness, and not just dark/bright?

        That's a pretty good idea. "Just in time" detection seems a lot more do-able.

        As for the question of what specific sequences, I think it probably depends on the patient. It wouldn't be hard to optionally detect a variety of patterns.

      I was thinking there could be a problem with DRM. We have those on non-Flash web vids, right?

        I think the intersection of video with DRM and video that induces epilepsy is near zero because if the video is valuable enough to put DRM on it, chances are the owner's got deep enough pockets to sue for causing a seizure.
