Welcome to this column of brief, blog-like articles about various UI design topics – inspired by my daily work, conference visits, books, or just everyday life experiences.
As in a blog roll, the articles will be listed in reverse chronological order – and if the roll becomes too long, I will start a new one.
Please note that the articles will appear at irregular intervals as time permits and inspiration comes... And from time to time, there may also be guest columns.

Many years ago, a former university colleague of mine told me a nice
story: On a shopping tour, he went into a clothes shop, discovered a
nice shirt, and spontaneously bought it. At home and in a pleasant mood
because of his great purchase, he opened his wardrobe to hang up the
shirt there. ...
Back
when I eventually bought an iPad, I reported on my change of mind regarding
mobile devices in this column and promised to share my "mobile" experiences
from time to time. In my last iPad report in February 2013, I asked whether
the iPad, or any other tablet computer, is a productivity tool – or
whether it could at least be used as one, for example, for the same kind
of work done on a laptop computer or whether the iPad could even replace
a laptop. But despite some indicators
that people also want to use their tablet computers in productive ways,
I found overwhelming evidence that people in my vicinity (including myself)
use their iPads primarily as a "tool for consumption." Here,
I will report on further evidence that, in my opinion, confirms
that tablet computers are primarily used as "consumption tools." ...
About
a year ago, at DKOM 2012, I heard about negotiations on a potential SAP
sponsorship for the Interaction Design Foundation (IDF) for the first
time. IDF is located in Aarhus, Denmark, and is well known and respected
in the design field for being "on a mission to make free and open
educational materials." At the German DKOM 2013 event in mid-March,
which was held in Mannheim, Germany, the sponsorship was eventually and
officially announced. "Gut Ding will Weile haben (good things
take time to ripen)," as we say in Germany. ...
Quite
a few weeks have passed since my last UI
Design Blink about multiple skyline graphs. It was written in response
to Bill Caemmerer's reaction to my articles about skyline
graphs (graphs that convey relative and absolute changes) and, in
particular, to my attempt at multiple
skyline graphs. In the meantime, and as promised to Bill and my readers,
I have taken a closer look at his version of multiple skyline graphs – and
feel that the time has now come to share my insights. ...
It's
more than six since I reported on my usage habits in the – for
me – new mobile world (Retrospect
after Five Weeks of Owning an iPad, Now
I Know What "Cloud" Means). Some readers of this column
might therefore be wondering why there has been so little news in the
meantime. Actually, my summer vacation caused a major break in my publishing
activities, and, thereafter, I had so much other work to do that I found
little time for experimenting or being "productive" with my
iPad. ...
You
may or may not remember that I attended the Interaction 2012 conference
in Dublin, Ireland last year. Not only did I write a report on
what I had seen at this conference, I also published two UI Design Blinks, Skyline
Graphs – New Insights on the Horizon... and More
Experiments with Skyline Graphs, about the topic of a presentation
that I was regrettably not able to attend: Bill Caemmerer's presentation Telling
the Data Comparison Story Using A Skyline Graph (Instead of Two Pies).
Luckily, an attendee told me about skyline graphs and briefly explained
the basic concept behind them to me. Yesterday, I received an e-mail
from Bill Caemmerer describing his latest investigations in multiple
skyline graphs – which were stimulated by my Blinks. ...

Many people still believe that everything on the Web should be free. Others regard the Web as a money-printing machine that will make people who take their chances rich. In fact, I would not be too surprised if, one day, we had to start paying for useful content instead of obtaining it free of charge. But even today, free Web content already comes at a price in many cases. The price that you may have to pay is that you have to look very hard to find relevant content on a page. In this UI Blink, I take a look at this trend and come to a surprising conclusion. ...
