I work in transportation human factors engineering and research for land, sea, and air. My work in usability/UX includes user interface design, design guide development, empirical testing, and expert evaluation. My human factors research focuses on automation, displays, and security and safety processes. I've advanced degrees in engineering and psychology and been working in the field since 1995. My contributions to this site are my personal opinion and do not represent the policies or position of my employer or any of its associated agencies. Not that anyone was wondering.

comment Meaning of message dialog icons - demand a prerequisite
@Oakley: Look it up in the Windows UX Interaction Guidelines. The "error" icon does not mean anyone or anything did anything wrong. I admit that I (and Microsoft) am ambivalent about using the scary red icon for minor problems, but I think it comes down to indicating whether there is something the user has to attend to in order to continue or not. That's an important distinction. That's the difference between an error and an information icon. You can't rely on users reading the message to know if something needs attention. User won't read something if they think they don't have to.

Actually, now that I look it up, the Windows UX Interaction Guidelines recommend no icon at all in message boxes for minor input problems. It's not worth getting alarmed over.

comment Meaning of message dialog icons - demand a prerequisite
I agree the word "error" should be avoided in messages and documentation because it can be taken to mean the user is at fault. However, I also think it's important for the user to easily and immediately recognize when there's a problem (as opposed to getting some other information). That's what the so-called error icon means, according to the Windows UX Interaction Guidelines, so that's how it should be used. It doesn't matter who's "at fault."

@Amon: If the user tried to do something that couldn't be done (e.g., submits before completing the required field), then it's an error and the icon is an error icon (this assumes that disabling the submit button is a bad idea -there are situations). Thanks re the links -fixed.

comment How to display UI operation delay
@Wolf: References updated as best as I could. Maybe time runs faster 3 years later, but, in my experience, feedback of activity has gotten worse, as mostly seen in web and mobile apps.
