Can labels be too much of a good thing?
I came across the following door at our local medical centre the other day:
The other side of the door looks the same (with exactly the same handles) but with a label “pull”.
Yet the door can be pushed or pulled just as easily, so it makes me wonder why they have bothered to label the door??
The handles above afford pulling more than pushing, however they can be just as easily pushed.
I wonder if this is actually confusing users rather than helping them? The only way to find out would be to perform some usability testing, but my personal experience has been to pull the door open on either side.
