That was Macoun 2011

Tuesday, October 4th, 2011

Macoun 2011 is over and I just arrived back in London. It was my first time and I was impressed with the quality of speakers and talks, people’s incredible openness and how brilliantly it was all organised. Also, thanks everyone for their lovely feedback on Twitter. I tried my best to retweet the most relevant tweets regarding gesture recognition, many more can be found using the #macoun hashtag.

The whole session was also recorded on video and will be posted soon. Meanwhile, here are some first pictures and the slides of my talk to download:

Gesture Library at Macoun 2011

Monday, September 26th, 2011

Less than a week left till the biggest iOS and OS X developer conference in the german-speaking world starts. Macoun 2011 will take place on the first weekend of October in Frankfurt am Main, Germany. I’m proud to be one of the speakers in such an amazing line-up. My session is going to be on Sunday, 11 am (Grosser Saal). So for those developers who still want to sign up and attend, today is the last day!


The talk is going to be about the Gesture Library on the iPad 2 and is going to focus on the concepts and technology behind it. We will also look at some code samples. Here an abstract of the talk (Source:

Visuelle Gestenerkennung

Gestengesteuerte Interaktion mit einer virtuellen Umgebung — ganz im Stile von Minority Report — ist dank Front-Kamera auch auf dem iPad 2 möglich. Anhand einer Beispiel-App werden die spannenden Möglichkeiten solcher Anwendungen gezeigt und einige dahinterliegende Technologien und Konzepte erläutert.

I still have a lot to prepare, only so much: People who were waiting for Meteora might really like it :)

Roll it! for iPad and other news

Saturday, April 10th, 2010

A lot has changed in the past months. First of all, “Roll it!” for iPhone still selling well all over the world, with over 2400 people having downloaded it (since the launch in December). I receive a lot of positive feedback and the game currently ranks in the top 20 of dice games in 5 countries. Additionally, with the upcoming iPhone 4.0 and features like Game Center, stay tuned for exciting new features.

Also, “Roll it!” for iPad made its way into the AppStore and was available since the iPad US-launch on April 3rd. New high-resolution graphics, a 3D splash screen and a landscape mode make the game even more fun to play.

I just wanted to post a little update on how the game is doing. It’s is very popular and since December 2nd, over 1100 copies have been sold. There is also a new update coming out in the next days – it’s already been submitted to Apple. It contains localisation for the Czech and Swedish language and addresses a bug in the random generator and the auto-resume function.

Since “Roll it!” made its way into the AppStore last week, the number of daily downloads keeps increasing. It’s great to see how it gains popularity. According to, it’s already Top 50 (44) in the category Games/Dice in the US store. The feedback is amazing and I’m really happy the app finds such an echo. In the meantime, version 1.0.1 got released, fixing a problem with the vibrate setting and correcting a word in the german localisation.

The never-ending story …

As a Mac user, I often get asked what is so special about Macs and “Isn’t it just because you want to be different and are deluded by their great design?”.

In this article I want to show you a few interesting facts that you might not have known. (more…)

Processing and TextMate in sweet harmony

Saturday, September 20th, 2008

Processing is a great tool, but to be honest, the code editor could be better. Fortunately there is an easy way to integrate it into TextMate.
