I was observing the low-usability of the buttons on the elevator of my building…
To choose a floor you must slide your finger on the button or simply touch it. The feedback of this action is a sound and a light, but there is no indication of where the finger should be slid.
The sensor is not in the full extent of the button, just in the middle and in one side. The other side has an indication of the floor in Braille. The fact of having information in Braille is another curious fact … because the elevator doesn´t indicate (with non-visual information) on which floor it is… how blind people will know on which floor they are?
And you may notice that the buttons don’t have a standard position. The buttons on the right are a reflection of the buttons on the left side… Null accessibility.
I really like pushing buttons and I think I’m not alone. Several times I saw broken buttons and nervous people trying to push this piece of hard plastic with a sensor inside it. Many people do not understand how this “modern” button works, so they try to push it stronger.
Apparently it’s obvious that there is no sensor in the Braille’s place (how blind people could read without selecting many floors) but a logical thing isn’t necessarily easy and intuitive.
It’s not intuitive thinking about a button that cannot be pushed….

Emotions, we now know, change the way the human mind solves problems – the emotional system changes how the cognitive system operates.

I started to read but I didn´t finish yet. I believe it won´t take long. I recommend.

I thought that change my background image on Twitter would be an easy task… I was wrong.
Step 1:
Find a nice image… Ok =)
Step 2:
Hum… I don’t know. Maybe wait…
Step 3:
Still waiting…
Nothing happens… no status bar… no boring messages. Ok, I can wait… no I can’t wait! Maybe if I click on this fancy white box something will happen… but nothing happens again.
I decided to click on ‘Save Changes’ button and Twitter saved my old background image. It wasn’t what I was expecting.
I returned to the Step 1… and waited… like some kind of magic (upload without feedback) my new backgroud appeared in the fancy white box and in the Twitter page. Apparently everything was ok.
Step 4:
Click on ‘Save Changes’ button. Finished.
