It would be interesting to see some data on how regularly drivers actually do check their speed.

You need somewhere for people you are testing who turn up too early to sit.

comment Why do we say that door knobs afford twisting?
That paper is a good summary: I've always found Gibson's view a bit metaphysical. Somewhere in POET Don points out that if you have to add a sign on an interface then its 'affordance' has failed !

comment Why do we say that door knobs afford twisting?
Part of the clue to affordances is size relative to the hand: If the round handle was 0.5 metres in diameter then it would not easily 'afford' turning. Affordance theory came from JJ Gibson way before Don quoted it. The background is given in Gibson's 'Ecological Optics' work. en.wikipedia.org/wiki/James_J._Gibson

Off the top of my head I think Don's door handle examples are more to do with whether its a push or pull door and how that's signalled by the handle design - and not these kinds of door handles. BTW - The original 1988 Basic Books edition is called "The Psychology of Everyday Things".

I'd be surprised if this wasn't in the OSX Human Interface Guidelines - developer.apple.com/library/mac/documentation/UserExperience/…

comment How do people know to “double tap to like” in Instagram? What did Instagram do to make users aware of that feature?
There is a rather weird theory of how knowledge can spread: en.wikipedia.org/wiki/Hundredth_monkey_effect

comment Does the average web user know about Boolean algebra?
Yes its quite heavy going: however it covers experimental evidence that people aren't good at 'formal logic' which of course is what boolean is all about.

comment How can I get people not to put trash in recycling bins?
There's also a 'compliance' effect which you can demonstrate experimentally: if people can see that other people have contaminated a container - then they are more likely to further contaminate it.

comment Should I avoid using “abort” in favor of its synonyms?
That's a good point: aborting is the act of stopping something which is already in progress (although you could obviously just 'stop' the mission, but it doesn't sound as dramatic and technical).

comment Should I avoid using “abort” in favor of its synonyms?
Its also rather a 'dated' word - I'd associate it putting men on the moon and 'aborting the mission'.

comment Where to position Back and Home buttons?
Just a personal opinion - but for me 'back always takes me to the left - so the 'back' icon should be on the left hand side.
