comment Product design materials
It may or may not be groovy depending on what the design goals were. There isn't "a" rule. The number of materials depends on the interplay of dozens of things.

++ to this Type I error is a very likely explanation if you're running lots of tests.

comment How many images should a slideshow carousel rotate automatically?
I would second what @AlexeyPegov said. In every usability test I've done with carousels the people using the site have either not taken notice of them, disliked them, or not actually followed up on anything past the first image. Yet to see them work in a useful way. Don't know why people use 'em.

comment Simulate Eye-tracking by Photoshop filters?
@GaëlLaurans - Yup. Completely right. As I said "mild oversimplification" ;-) And obviously some cues for gaze path must be coming from the peripheral vision - motion across the visual field being the most obvious example. But I think that things like the F-pattern show that there's a lot of higher-level drivers for gaze path too. Visual frequency is, I think, unlikely to be a useful cue by itself.

comment Simulate Eye-tracking by Photoshop filters?
@FrankL Finally, we know from observing eye tracking results, that our attention is being driven by much higher-level abstractions (e.g. our tendency to pay attention to faces, the F-pattern in left-right-top-bottom reading cultures, etc.) unrelated to the frequency info in the image.

@FrankL The the second is comparing low/medium/high frequencies so they are basically talking about stuff that's coming via the fovea and, by definition, what the eye has already looked at. So no input on eye tracking behaviour their either. I'm sure that frequency will have an effect - but it's going to be a complex feedback driven one based on the model generated via the processing in the visual cortex.

comment Simulate Eye-tracking by Photoshop filters?
@FrankL The point I was trying to make was that those papers aren't (as far as I can see) talking about low frequencies steering the eye in the way that eye tracking studies are normally used. They're talking about figuring out the model for how different frequencies are integrated. The first is talking about its effect on slow-pursuit eye movements - which are different from the fast "unconscious" saccades that eye tracking studies normally focus on (I don't have access to the full paper so may be missing something).

comment Simulate Eye-tracking by Photoshop filters?
@FrankL All eye tracking heat maps are is a view of how much total time was spent "focussed" on areas. They're often aggregates from multiple users. They don't let you know if somebody comprehended what they were looking at, or whether the gaze was conscious or unconscious. E.g. I've seen eye tracking studies that showed many people fixated on an area, but their behaviour and follow up questions showed nobody had actually read the text (it was in a banner blindness spot). This sort of thing is why I rank eye tracking as one of the least useful general user testing tools ;)

Erm.... I don't think the OP is suggesting delaying the email. They are suggesting exactly what you're recommending. Send the email - but don't block access until the user has validated it.

comment Limiting access before email address is confirmed
@Captain Also there are people who (a) want to register where they cannot access their email, or (b) have email that is slow so blocking access until validation prevents them using the site.
