Some time back I picked up a PDF on malicious interfaces. I've attached the PDF to this post for reference. Basically, it's the use of UI design to effectively coerce the user into considering material (ads, etc) that they don't want to deal with, or to create an outcome that may run counter to what the user actually wants to do.
It's not something that I've found a lot of research on. The PDF I've attached is one publication. I can't remember where I picked it up, but it was being distributed for free. I know another one is floating around somewhere, but that's the extent of my knowledge. I would have though there would be more information on this. Does anyone have insight into this trend?
