The designer’s “I think the controls are intuitive”-claim

Posted in Uncategorized on August 12th, 2011 by roman

When I hear or read that line, it’s like a red flag in front of a bull, a warning light. It’s translation is: “Hello user experience, haven’t seen you for a while, but I got it right.”

The best addition to it is: “…and no manual is needed.”

Why is a white-text-on-black theme a poor choice?

Posted in hci, internet, usability on September 26th, 2010 by roman

Try to read such text in low light, such as in the evening with just a little reading lamp on. Try a wider paragraph width, larger line-spacing. A 150% of this blog will make it too.

Then look away from the text. You won’t see a thing, but just nice blinds, all ‘burned’ into your retina. The recovery of vision seems much longer than from a black-on-white scheme (reading a newspaper on a direct sun).

And why do I then use the scheme? It looks good. But after this experience, I am considering a change to basic.

Deadline extensions, everywhere

Posted in Uncategorized on March 31st, 2010 by roman

It seems like every conference, workshop, and meeting now sends out deadline extensions (including the events organized by us). Can the financial crisis be the cause that there is not enough submissions?

Pearls of today

Posted in life, research on February 18th, 2010 by roman

During today’s interview with Henrik Hansson, I produced few bright ideas for which you can quote me (paraphrased, the original will be soon online, hope not):

R: “You go twenty kilometers away from Joensuu and there is nothing.” – when comparing North-Carelia with Africa.

H: “Is there any special characteristics a phd student must have?” R: “Let me think for a while…hm, no.”

R: “If I don’t hear anything from a student in one week, I start to be afraid he might be sick!”

H: “How did you select the topic of your thesis?” R: “Well, we were building a usability lab, that’s how it happened.”

The Lisbon Treaty and the Czechs

Posted in politics on October 17th, 2009 by roman

You must have heard about the ratification process of LT. At the time of the writing, most countries 26 out of 28, the Irish included (they had a second go and said OK), had approved=ratified the treaty. Italy is just depositing the documents, so we have one and only remaining country. (Now, there is some talk about Ă…land, but let’s keep it out of business, no pun intended).

The last one is the Czech Republic. Can you now use the best of your imagination, and tell us all, what is the real reason?
