Now that you've taken the quiz, let's evaluate the options available for this usability problem.
So, what was the solution that you went with?
0:00
Well, let's go through some of the options and we'll figure out which one is the best.
0:03
We could put up a sign next to the badge reader.
0:07
The sign would be descriptive.
0:10
It could be a nice laminated sign or even a sticky note
0:12
that tells people to use this badge reader to open the door over there.
0:16
But that's doesn't help the people who come to the door
0:20
and don't see the sign or the badge reader.
0:23
There's still a miscommunication here and it's still not usable.
0:26
Now, we could put the sign next to the door
0:31
that tells people to use the badge reader across the hall;
0:33
however, the sign could be lost.
0:37
People could have trouble finding the badge reader.
0:39
Still, it's not the best solution
0:42
and clearly, doing nothing is not going to help this confusing situation.
0:45
In this case, the ideal option is to move the badge reader
0:50
and put it next to the door that it controls.
0:53
The idea here is that the proximity of the 2 objects
0:56
will create an association that people will easily understand.
1:01
They'll know that one thing controls the other.
1:04
So, in this case, that's the solution we want to go with to improve usability.
