Wow that sucks!

Not to be able to watch movies or drive or anything.

Does it bother you to turn your head fast too?

From your post I am presuming that it does and I would be curious how you deal with it?

Fast flashing gifs give me a headache, but not movies, driving etc. For me, it's not the movement, but that an extraordinary amount of movement is happening per second.

Perhaps one of you gif posters can use the tool below and report back on the gif flicker rate of the strobing gifs.

Do Your Flashing Ads Cause Seizures?

Flickering, flashing and strobing effects on webpages can cause some people to have photosensitive seizures.

How Common is Photosensitive Epilepsy?

According to the National Society for Epilepsy, “one in 131 people have epilepsy and of these people, up to 5% have photosensitive epilepsy.” This means that for every 10,000 readers or visitors to your site, four or five people could have a tonic clonic (convulsive) seizure caused by flashing ads, animated GIFs or flashing red text.

What are the Recommendations for Bloggers, Internet Marketers and Web Designers?

The two guidelines related to making web content safe for people with photosensitive epilepsy are:

1. The Web Content Accessibility Guidelines (WCAG) 2.0, Guideline 2.3 requires webpages not to have any content that flashes more than three times per second and no more than three red flashes per second.
2. The US legislation Section 508 of the Rehabilitation Act, which applies to all Federal agencies, states in subsection 1194.22 Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz.

How Can I Test Flickering Speeds?

For a quick test, download the Web Accessibility Toolbar for Internet Explorer (the lack of toolbars for other browsers is another accessibility issue!).

Once installed, click on Images (keyboard shortcut: alt + 4) on the toolbar, then select GIF Flicker Test. You’ll be presented with a basic report indicating which GIFs have flicker rates within the range that may affect people with photosensitive epilepsy.

For a more in-depth analysis, check out the Trace Center’s Photosensitive Epilepsy Analysis Tool (PEAT) – a free, downloadable resource for developers to identify seizure risks in their web content and software.

What is the Bottom Line?

Even if the object does not cause a seizure, it may cause nausea or dizziness in some people. Neither of these is as serious of a health risk as a full-blown seizure, but having users mentally associate your web site with feelings of nausea is probably not the best design decision, at least in terms of user satisfaction and repeat visits.

a lot of it is not the speed of the gifs which run typically between 10 and 30 frams/sec, worst case some may run as low as 4 due to size issues, and movies are 30.

People with antiques have more problems with their junk video card update speed than the gif flash rate and the flash rate of gifs usually do not go from one contrast extreme to another in one or two frames on a continual basis, they tend more so to change over several if not several hundred frames before there is high contrast change.

As I said earlier anyone that sensitive may want to consider not using the net at all for obvious reasons.

Most gifs that I posted were between 7 to 10 frames per second, how they look beyond that is up to their internet speed computer speed and their video card matters etc etc etc.

just because you think you are the be all / end all of all things doesn't mean that your personal experience applies across the board.


just sayin'.

Greetings

I would also like to add that some forums ban moving images as they can make people with Epilepsy have a seizure. I do not have epilepsy but I do have a problem with getting nausea and the like form that type of files for they move so quickly and repeat the movement again, and again and again. A thread with such images will be unsafe and unreadable for a pretty large amount of people.

I wish you all well

Thank you, thank you, nephandi, for bringing this up. My nervous system is VERY sensitive, especially to visual stimuli, and those moving files create much pain in my brain and spine, and overwhelm me. For survival's sake, I must make them disappear as soon as possible. The only other option I have is to quickly move off of that person's post/avatar, so I end up missing what they write.

Wow that sucks!

Yes it does, at times.

Not to be able to watch movies or drive or anything.

I can watch old timey movies, where movement, lighting and sound effects are normal and natural. Most movies today I cannot watch, as they overwhelm my system, can bring me to my knees, and cause me to go into the flight survival mode to remove myself from it as quickly as possible.

Does it bother you to turn your head fast too?

No it doesn't.[/b]

From your post I am presuming that it does and I would be curious how you deal with it?
I deal with it by carefully limiting my exposure. I don't go where most people go. I don't do what most of them do.

Imagine if all your senses; sight, smell, hearing, taste, experienced things 5 or more times more strongly than they already do. You would overwhelmed by loud noises, yelling, strong reactions to common, unatural smells (mechanical, chemical, etc.). It would exhaust you, and you'd be forced to remove yourself from them so you could carry on. It's kind of like being in a room full of 8 babies screaming at the top of their lungs. It wears you out quickly. You become very irritable, frustrated and angry, and all you want to do is get the hell away from it.

Imagine being so sensitive to others energy fields, that you picked up their internal states from 30-50 feet away, and knew what was going on inside them. Then imagine them standing 2 feet away from you in a checkout line, where you're picking up all their s**t, stress, anger, fear or instability. Talk about overwhelming and draining.
