comment Comparing mouse + Keyboard vs Touch Screen Input Devices?
I think the question could be usefully rephrased around 'design guidelines for touch / non touch interfaces'

comment Would you consider Trolls while creating personas?
In designing an online discussion system you should consider various classes of misuse: trolling is one; but another is the creation of 'SockPuppets' en.wikipedia.org/wiki/Sockpuppet_%28Internet%29

comment Is there any evidence to back up the theory elderly people won't know how to use a smartphone?
Worth noting how the linked study defined 'seniors' ... "which was defined as 68 and older".

comment User Testing Framework and Questions for comparative tests
Typologies are essentially vague and broad brush (and can just end up with endless arguments as to what fits under which category) I think you're in danger of trying to make something look accurately measurable that actually isn't. ( There are "Lies, Damn Lies and Typologies" ... )

comment Might a design be “too good” for users that expect a low price?
Its also worth pointing out that not only is much academic research on cognitive science based on American/European audiences but much academic research uses 'college students' as they often form a handy pool of free research subjects in the same building...

comment What do you do when the user interrupts the purchase process?
You also don't want it to reset too quickly as the user goes off to hunt out which jacket / coat has their wallet in so they can find their credit cards.

comment How to design a “data usage calculator” for a brand new smartphone users
PS - the key criteria is how much you'll be using the phone away from your home wi-fi. If you use it mainly at home then you won't be using much of the mobile data.

comment How to design a “data usage calculator” for a brand new smartphone users
Currently you've written this as a 'consumer question' so it will get closed. However if you re-word it as 'How do I demonstrate to users what 1GB of data actually looks like ?' its a useful question which mobile phone companies might want to take note of on their websites.

comment The “Mental Model Law”
I think the earliest reference which comes to mind is Bartlett (1932) with the War of the Ghosts experiment: asbib.wikia.com/wiki/… The bottom line is the same: what you see is what you THINK you'll see (ie new knowledge depends on existing knowledge).

comment The “Mental Model Law”
And I see Don submitted a chapter on a book on the topic back in 1983...en.wikipedia.org/wiki/Mental_Models_%28book%29 as well as pretty well defining UX "So the job of system designers is to help users form an accurate and useful mental model of a system. And the job of researchers is to set up experiments to learn to understand actual mental models, even though they may be messy and incomplete"

comment Verbs and actions in Dutch
Off topic, but one of the other issues with localising in other languages is that the words are longer and don't fit on the buttons unless the font is shrunk...

comment What are the differences between Usability Attributes and Usability Requirements
I'd argue that the users mental model, the designers mental model and the system image are key UX concepts (covered at length in Don Norman's 'Design of Everyday Things')

comment What are the differences between Usability Attributes and Usability Requirements
Or to put it another way: does the system do what the users want it to do - and can they figure out how to do it ?

comment B2B / B2C, as one or two separate websites?
Financial Services sites have this dilemma eg hsbc.co.uk. They also tend to hide the corporate stuff away under a link down at the bottom of the main site.
