Cell Broadcast story - UI/UX
-
Hello all,
I've started to have a look on the Cell Broadcast feature.
The first step we can have is to just display a Notification for Emergency one, but we need to think to implement the full feature.there will be several levels of alerts and types.
Level 1: Critical, the notification should use a "critical" alert sound along with a persistent popup.
Level 2: Extreme, attention alert sound with persistant popup
Level 3: Severe, attention alert sound with persistant popup
Level 4: Public Safety: attention sound with ephemeral popup
Amber ( child abduction): attention sound with ephemeral popup
Tests: attention sound with ephemeral popupSo the question for now is: Which icons to use,
security-alert
?
, and we would need to add specific Alert Sound ( critical + others). Which one could be used ?ref: https://forums.ubports.com/topic/7798/the-cell-broadcast-story

@lduboeuf
Are you talking of the states alerts using already implemented in mobile standards, like EU is promoting, and that France recently, and finally, adopted ? -
@keneda yes

@lduboeuf
That's really good news, thank you very much for your work on UTWhat "security-alert" icon looks like, can we see it somewhere ?
For sounds, can't it be like for sms, user choice ? -

That's really good news, thank you very much for your work on UTThanks, will try my best, but UT code is not always easy for me. Hope i will win [EDIT]: Contribution welcome.
What "security-alert" icon looks like, can we see it somewhere ?
see https://docs.ubports.com/projects/icons/en/latest/
For sounds, can't it be like for sms, user choice ?
We should have a "default" alert sound as usual and then best would be to add a custom sound yes.

For the icon it seems OK, but I would suggest:
dialog-warning-symbolic
orbroadcast
colored redAnd thanks for your efforts.

dialog-warning-symbolic or broadcast colored red
Or both or a mix of it ^^

On other phones it sounds really noisy and like an there's an actual emergency....if we are takling about the same thing I think the default sound should be really attention grabbing.

So if anyone can propose a default Emergency sound and a less "noisy" one, would be awesome
For the icons, we could use the default warning. And maybe play with colors ( Red/Orange/Yellow) according to levels of alert. -
@lduboeuf at least for the US we have this multi-tone ringing https://www.youtube.com/watch?v=sxF2c_nhiGM

Is it going to be opt-in or opt-out?
Also full Cell Broadcast is much more than emergency alerts - we had something like Craigslist in Poland that was based on CB in early 2000s - it's probably not active anymore since the carrier is also gone, but if you want the full experience we also need an info "level", a screen with message history and another to select channels to subscribe to (maybe with the ability to define per-country channel id <-> name mappings?).
And definitely a way to silence a channel while still being subscribed - for example it doesn't make sense to get alerts from channel 50 for most countries, but checking it manually is a valid use-case.
-
@klh First iteration lets make it simple, and convey the alert categories without too much persistency and UX.
Also, messages can be added into messaging-app maybe, as special senders, and then they can be persisted also. But UX for showing and selecting available channels would come much later.
-
@flohack In general I'd agree, but from my understanding CB is/was opt-in - one of the reasons we got an SMS based emergency alert system instead of using CB here. But I don't suspect a government project of doing proper research, so it wouldn't surprise me if the info in the documents was wrong
