Oof. I’ve just had to rapidly nope out of Cult of Luna because of the coloured strobe lighting. Wtf? I’ve never had photosensitivity before. Insta-nausea.
Anyone else experienced this?

If you're watching the opening ceremonies, there are some flashy bits around the 35 minute mark that could cause problems if you're photosensitive, so be aware. (I recorded the earlier showing so I'm a little ahead.)

I get the cameras on max that we don't see Next came the full screen surveillance on buses that sorta flashes when it repositions- I try not to sit on that side #photosensitivity #seizures but now apparently the platform cameras have been integrated into the fare machines so when noone is buying a ticket, it's watching you. #surveillance isn't always a good thing- #anxiety #neurodivergent

Last night, I tried to watch A New Hope for the first time in decades. Within the first five minutes, the flashing lights triggered a #migraine (not the laser fire itself, but the way the screen periodically went white when there was a hit).
The last time I watched Star Wars was on DVD and I don't remember this. Is it something to do with the upscaling? Disney Plus? My own device?
If it's part of the film, I'm really confused why there's no warning for #photosensitive viewers at the beginning.
Would really appreciate my fellow #disabled peeps helping me out with this one, because I'd like to watch Star Wars again.

@loops should have settings / toggle for photosensitive people. Probably as a standardised message on a CW. It doesn't affect me very much, but sometimes I'd prefer not to see flashy videos. It'd be a must-have for anyone who is actually photosensitive, and make #LoopsVideo more accessible.

CW: What is an Ecology of Protections?
What is an Ecology of Protections?
In our paper, we illustrate how social media and information infrastructures can be imagined as an ecosystem of agents interacting through processes (policies) and behaviors (actions of users and automations).
This ecosystem model makes it possible to understand how our current protections for photosensitive users are inadequate, allowing for multiple vectors of accidental and malicious exposure to dangerous flashing content.
[Image 1: Narrative Description of Diagram:
Platform Executives and Marketing Clients have a cyclical revenue relationship.
Platform Executives influence Platform Designers and Developers.
WCAG guidelines are meant to support Designers/Developers, but may not always be followed.
Marketing Clients sometimes create flashing content.
Non-sensitive users who are unaware of photosensitivity may also create and share and circulate flashing content, which can lead to accidental exposure for Photosensitive Users.
When Non-sensitive Users who are aware of photosensitivity are exposed to flashing content, they may warn photosensitive users.
Non-sensitive Users who are aware of photosensitivity may also intentionally or maliciously expose sensitive users.
If any user attempts to report a flashing graphic, reporting features do not have appropriate categories, and platform developers are never notified of the problem.
Sensitive users may also experience resets or overrides to their safety settings on major app updates.]
A more robust ecology of protections centers the photosensitive user, even though they are not "the majority", providing them with multiple layers which they can control to protect themselves from exposures when other policies and community norms fail.
[Image 2: Narrative description of the aggregate re-world map.
The photosensitive user is protected from ambient, accidental, and malicious exposure by a dual layer of protection by device level settings and app level settings.
If a developer update overrides app-level settings, the device level settings correct this.
Users who are aware of photosensitivity are able to educate other users to prevent circulation of dangerous content.
Advertisers and other users may still create and share flashing content, but an enforcement body can punish advertisers and platforms for creating or failing to prevent the circulation of flashing content.
Users are able to report dangerous content to both the platform and to regulatory bodies.
Malicious attacks are met with suspension or bans.]
Such a nested system of protections can prevent ambient, accidental, and malicious exposure to dangerous flashing media. Establishing these features and community norms may further protect all users from psychologically harmful content.
It is important to note that such provisions rely on centering user safety over corporate interests which rely on non-vonsensual auto-play to hook user attention and manipulate purchasing behavior. To this I say, get more creative. Or maybe... stop being a predator.
Additionally, the central layer of protection requires implementation by OS developers to provide an optional postprocess filter which can inturrupt dangerous luminance shifts at the pixel buffer level. Other research attempts to classify and predict dangerous flashes through ML techniques, but this is not necessary. A always-on simple algorithmic edit to the next array of pixels provides fail-safe protection at a minor aesthetic expense - a ghost or trailing effect.
[Image 3: An original sequence of frames which flash between pure black and pure white.
A flash detection mask is calculated and a pixel-attenuation filter is loaded.
In the final sequence, each frame is attenuated by the detection mask and filter, producing the impression of a flash without the actual danger.]
Image 3 demonstrates the proposed filter applied to a full screen blink sequence. Between-frame calculations of flash detection using South et al.’s algorithm would produce a full white mask for each frame, indicating that each frame change was dangerous and needed to be adjusted. In other examples, the calculated mask would identify specific regions for pixel filtering. The mask could then be applied to a calculation which adjusts how much the next frame transitions between the previous frame and the intended next frame. In the example here, frame 2 becomes frame B, which is two plus the mask (Δ1), multiplied by a fraction (q). Frame 3 becomes frame C, which is the original frame 3 plus the calculated difference between frames 2 and 3 (Δ2), minus the pixel values in frame B. The first flashing sequence is significantly faded, and over time the flashing sequence averages out to show level changes without strobing.
This effect may look strange, but photosensitive users already use "unaesthetic" filters to limit the overall brightness of their devices. Such filters may even enable content creators to change their aesthetic choices to eliminate ghosting which would indicate a safer content for all.

Yesterday, my students presented our work at the ACM ASSETS conference. "Not Only Annpying. But Dangerous": Devising an Ecology of Protections for Photosensitive Social Media Users" https://dl.acm.org/doi/abs/10.1145/3663548.3675610
In this study, we investigate prior work, conduct survey inquiries, and use co-design methods to explore how social media design choices influence exposure to dangerous flashing content which can trigger seizures, migraines, nausea, and disorientation for photosensitive users.
Through our analysis, we identify the current ecosystem of flashing content on the Internet, and propose a more robust ecology of protections, including on-device graphics filters that directly edit pixels buffers to prevent flashing before it occurs.
First, existing WCAG guidelines against auto-play of media need to be enforced. Second, users should have device level control over animation that may trigger flashing, and this control shpuld not be able to be reset by platforms that try to enforce autoplay to support their own ad revenue. Third, other users need to be aware of what makes content dangerous, so thay they may stop circulating it and causing accidental exposure. Fourth, creators need to know what makes content dangerous, and how they can test for danger, to prevent them from creating dangerous media in the first place. This includes corporate creators, like movie studios, whose ads for acrion movies have been a recent source of autoplaying strobing content in movie trailors posted via ad platforms. Fifth, platforms, including GIF libraries, but also all social platforms, need to implement reporting mechanisms specifically for flashing content which can remove that content from circulation. Sixth, there should be actual penalties for platforms and creators that do not react to, correct, and remove dangerous content, or who force auto-play on users.
And seventh, device manufacturers and operating system developers need to create on-device filters that eliminate flashing through simple real time post-processing. Machine Learning classification and prediction algorithms ARE NOT NECESSARY. We can do this with simple math. Yes it may sometimes look weird. But also people won't be dying in their sleep.
This work is very important to me, and I've been working on it (on the side) since 2017. I wasn't allowed to pursue it fully as a graduate student. As faculty, I still had to string the project together on wishes. And I'm still looking for a collaborator to work on the implementation, though if industry would just get their shit together and do it themselves, that'd be great.

And I'm still looking for a collaborator to work on the implementation, though if industry would just get their shit together and do it themselves, that'd be great.

Yesterday, my students presented our work at the ACM ASSETS conference. "Not Only Annpying. But Dangerous": Devising an Ecology of Protections for Photosensitive Social Media Users" https://dl.acm.org/doi/abs/10.1145/3663548.3675610
In this study, we investigate prior work, conduct survey inquiries, and use co-design methods to explore how social media design choices influence exposure to dangerous flashing content which can trigger seizures, migraines, nausea, and disorientation for photosensitive users.
Through our analysis, we identify the current ecosystem of flashing content on the Internet, and propose a more robust ecology of protections, including on-device graphics filters that directly edit pixels buffers to prevent flashing before it occurs.
First, existing WCAG guidelines against auto-play of media need to be enforced. Second, users should have device level control over animation that may trigger flashing, and this control shpuld not be able to be reset by platforms that try to enforce autoplay to support their own ad revenue. Third, other users need to be aware of what makes content dangerous, so thay they may stop circulating it and causing accidental exposure. Fourth, creators need to know what makes content dangerous, and how they can test for danger, to prevent them from creating dangerous media in the first place. This includes corporate creators, like movie studios, whose ads for acrion movies have been a recent source of autoplaying strobing content in movie trailors posted via ad platforms. Fifth, platforms, including GIF libraries, but also all social platforms, need to implement reporting mechanisms specifically for flashing content which can remove that content from circulation. Sixth, there should be actual penalties for platforms and creators that do not react to, correct, and remove dangerous content, or who force auto-play on users.
And seventh, device manufacturers and operating system developers need to create on-device filters that eliminate flashing through simple real time post-processing. Machine Learning classification and prediction algorithms ARE NOT NECESSARY. We can do this with simple math. Yes it may sometimes look weird. But also people won't be dying in their sleep.

Strobe lights are one of the largest banes of my existence. It’s difficult, and personally embarrassing, to be a highly sensitive jam band fan. #phish #highlysensitive #highlysensitiveperson #photosensitive #photosensitivity

Still working on the All Your Breath Are Belong To Us video (gradually) and actually might be getting near completion (ha ha yes); audio here: https://www.tumblr.com/pipzeroes/728731254678290432
More context in the thread: https://zeroes.ca/@pip/110069652708129811
One thing, though, is that I'd like to emulate the original video sequence at the coda, the end part of the song where it's like "BASE BASE BASE BASE...!" (except it's "BREATH BREATH BREATH" etc.)
It'd be a bunch of images quickly changing, a different one for each "BREATH" (16 images in under 4 seconds).
The thing is, though, that for some people quickly flashing images can have consequences (photosensitive epilepsy, nausea, migraine etc.)
This is the original sequence https://www.youtube.com/watch?v=qItugh-fFgg&t=231s (video queued to that point; warning, quickly changing images, in case viewing stuff like that is an issue for you- and also, uh, it might be a bit loud, so, warning if you are on headphones).
I know that the risk of photosensitive epilepsy is increased based on the frequency of the flash (that is, how quickly the light is flashing), the brightness, and the contrast with background lighting...
So, I am thinking:
- Instead of having the images flash in their order of appearance, sorting them so it only goes light-light-light-dark-dark-dark instead of light-dark-light-dark-light-light to help reduce the risk.
- And if it does reduce the risk but there could still be risk, how I would word a note beforehand to be concise and effective...
Any other thoughts from those with experience mitigating these kinds of risks would be appreciated; thanks.

🇬🇧 Dark video due to #Photosensitivity. I spend the afternoons resting on the armchair with indirect lighting behind me.
🇪🇸 Siento la oscuridad. Los vídeos salen con menos luz que las fotos. Pero la #fotofobia manda 😎 y me paso la tarde en el sofá con la lámpara de luz indirecta detrás.
