When you discuss target audience in a design phase, I think it’s a very good process to describe the various audiences in terms of personas. Anything that can serve as a support in that regard should be taken into consideration. Including behavioral patterns as you describe them in your article.

I do find it the most useful however, to envision the personas on a very personal level - Who do I know personally who has similar traits? How did I feel when I was in that particular age? And so on…

My post above however, doesn’t take audiences into consideration at all. It’s merely an attempt at describing a process that I find useful when designing user interfaces for any audience.

But what about non-verbal personalities? How should they carry on this dialog? You know, the people who can’t stay in their seats. They have to gesture or even grab a marker and draw pictures.

I believe UI needs to speak to personality traits like these. More on my blog:
