Exit Signage – can’t see, won’t see
Affordance & learned irrelevance
Conventional emergency exit signage suffers from two significant issues that severely compromises its performance:
- Poor, or a lack of, ‘affordance’
- Learned irrelevance
Let’s tackle these in reverse order.
Also known as the pre-exposure effect, it may be described as the learning to ignore things that lack meaning or have no impact on us. We see it all the time, it doesn’t affect us so we don’t see it.
What does this mean for the performance of conventional signage? It means it doesn’t work at all well.
Summarily, we are unlikely to see it and if we do see it, we are unsure how to react to it causing us to be indecisive just when a quick, accurate decision matters most. This is important enough in simple wayfinding terms let alone when we are trying to find our way to safety in an emergency. This increases stress and more critically slows evacuation, increases risk and puts lives at risk.
These are not only key to the lack of performance of conventional emergency exit signage but are all also key to why Evaclite dynamic signage was designed the way it was.
It is designed to grab the attention and convey a clear, intuitive message that we know how to react to.
It has been proven to be seen twice as easily, help you make up your mind in half the time and get you moving in the right direction twice as quickly. It is the brighter, quicker and safer choice.
