Same logic applies to knowledge gained from your occupation. The product design knowledge I gained has gifted me a magnifier in my daily life to evaluate almost everything I encounter. This leads to great pleasure when I see some excellent design from time to time, though unfortunately more often it leads to discomfort and a desire to shout out, which directly leads to this post.
I was visiting a local public service office whose phone was never picked up, so there was a long waiting line for walked in. When the office is closed, people started to walk out, and I notice the guy before me was really confused by the door. The door has a pushed-down handle as below, so he push the handle but the door did not move. He tried harder but the door stood still. He turned around looking confused. And it turned out the the similar looking door adjacent to it was for exit, while this door was for entrance. Why does a door have a push-down handle when you could not push it? Poor design. Haha, sound familiar, right? Search for 'Norman door' on Google. And afterwards, you will start noticing doors like this everywhere.
But how could I print from my mobile device? They ask me to send an email to firstname.lastname@example.org, but what happened after I send it out? Do I need to call the stuff there to print it out for me, or is there a printing queue within this machine that contains my file?
Then I look at the screen which list the following section. Which one should I choose? The only one with a mobile image is 'Print with retrieval code', but where can I get a retrieval code? Oh, I was thinking and thinking and confused!!
