Those that design stuff, physical and digital, should be required to use it in real life. Google "enhanced" its gmail interface so that every time you try to launch it, instead of going directly to the log in page, you end up at "Now a word from our friendly sponsor." And to add insult to injury, the default log on has been changed to "stay logged on." Google is one of the biggest culprits of "Dumb Design," perhaps because it is a company filled with engineers and no real people.
And then there is Amazon. I admit up front that making the charge cable double as a USB port is brilliant. However, the Fire (HD) charge cable is black-on-black. Yes, each end only goes in one way, but it is really Dumb Design to mark "This End Up" in stamped black, as well as being tiny, making it a real pain to get it right. I am looking at an example of "Intelligent Design" on the cable for a D-Link USB hub. It is black-on-black, but they recessed the "This End Up" indicator and made it larger, so it is a no-brainer to get it right.
All these tech companies profess to test human factors, but I wonder how much real world testing actually goes on. Microsoft (not picking on them, just have some knowledge) has long been a proponent of human factors, but you would never know it from using Windows.
Time for some real "Intelligent Design."
