My smoke detectors made a boast on the packaging they featured a fool-proof low battery indication, without going into any details.
I bought half a dozen of them to install in our new house years ago, thinking the nightly find-the-beeping-^+=¥€ games were finally a thing of the past.
When one started beeping, I did the rounds, figuring I'd be back in bed in minutes. Well, I wasn't. Turned out the fool-proof indication was to have the normally green LED flash red instead.
Did I mention that I am colour blind?
- michaelmior 9y agoUnfortunately as some who isn't colour blind and doesn't have any close friends who are, it's easy to forget about these concerns. I think attention to accessibility issues like this is one of the things that separates great designers from good ones.
- lb1lf 9y agoOh, it isn't all bad - now I get to kick my wife out of bed to find the offender, instead.
- mark-r 9y agoThe smoke detectors in my house are supposed to do that, but many times I've found one chirping and the light is nice and green.
