I once observed an elderly woman trying to use a computer. We were in a public library and she was standing in front of the computer, lifted the mouse in the air, aimed at the screen and clicked it like a TV remote.
I am still shaken by this image, but over the year came to this of this as a positive example of how we try to transfer knowledge from a familiar domain to a new domain, when aparent clues suggest this can be useful.
The woman became furstrated and embarrased since she realized a few teens who were very entertained by her ignorance.
