I came across this study in computer bild – you should not cite it as it in a scientific paper as “computer bild” – is consumer paper telling people mainly which computers to buy and how to use obvious features in software 😉
Nevertheless it is interesting and gave me some ideas what navigations systems are good for and it is another example that user needs on an abstract level (e.g. as in Maslows hierarchy of needs) could be interesting to inform designs.
If you do not read German here are the results in short:

Gilbert Beyer from Munich came to visit our lab. In Munich he is working on interesting projects that combine aspects of software engineering and human computer interaction in the group of Prof. Martin Wirsing. Gilbert participated in the pervasive computing in advertising workshop in Nara and we met there.
We discussed aspects of how to study and empirically evaluate larger and off-desktop interactive systems. Even though those systems differ significantly from desktop systems the book How to Design and Report Experiments by Andy Field and Graham J. Hole is still a good starting point.
Carting new territories is exciting… Continue reading
Ever wanted to cite the number of “Mobile cellular subscriptions per 100 inhabitance” in Albania, Algeria, Argentina, Armenia, Australia, …., United States, Uruguay, Uzbekistan, Venezuela, Viet Nam, Yemen, Zambia or Zimbabwe? Or the spending on mobile telephony or the computer penetration in these countries? Then the website I just came across may be interesting for you too: http://measuring-ict.unctad.org/
Here are the direct links to documents containing data:
- Measuring the Information Society – ICT Development Index
- The Global Information Society: a Statistical View
Some of the figures seem really high to me – but I have not looked into detail. They… Continue reading
There is a study that looked at how the performace in solving certain cognitive/creative tasks is influenced by the backgroun color . In short: to make people alert and to increase performance on detail oriented tasks use red; to get people in creative mode use blue. Lucky us our corporate desktop background is mainly blue! Perhaps this could be interesting for ambient colors, e.g. in the automotive context…

Wherever I meet with companies at the moment one of the first questions is “do you have good students – we need people…”. It seems good computer science skills are useful 😉 However to me it is not clear why so few people go into this field. Here is my favorite short list what you should have to study CS: (1) you are creative; (2) you are communicative; (3) you solve problems systematically; (4) you have an ability to generalize.
