Take a look at a pic above which I took this evening at a small restaurant. This is a machine for free drinks and you can see several buttons on it.
If you’d like to drink a cup of cold water, where do you touch? As you can see, most of people touch buttons on right side and that’s why the buttons are fading away. I also touched.
But, the buttons on right side are not clickable. It’s not a button but a label to show what kind of hot/cold drink you can get. I couldn’t imagine that even when I touch the label.
People keep touching the labels and then the labels are getting more like buttons. Why’d this happen? That’s because the restaurant haven’t maintained the button area ever. People make mistakes sometimes but we all have chances to recover it.
If your labels are fading away, it’s time to change something.
