Saturday, March 16th, 2013

The video of my Introduction to Games Programming (Grundlagen der Spieleentwicklung) is now online and available from www.macoun.de and on iTunesMacoun is the largest iOS and Mac OS X developers conference in the german-speaking world and takes place on an annual basis in Frankfurt, Germany. This session was held on October 28th, 2012 and is in German.

Pantomime 2.0 in c’t 10/2012

Monday, April 23rd, 2012

The six page article about gesture recognition has finally come out in c’t issue 10/2012. The magazine is seen as one of the most prestigious technology journals in the German-speaking world with a range of over 1 million readers (Source: Wikipedia).

The article is written in German, here a brief abstract:

“In der von Nintendo, Sony und Microsoft beherrschten Konsolen-welt gehört die Steuerung per Körperbewegung bereits zum Alltag: Von der Pflege des virtuellen Haustiers bis zur Gymnastikstunde im Wohnzimmer gibt es reichlich Einsatzmöglichkeiten. Bei Mobilgeräten wie dem iPad bleibt dieses Potenzial bislang weitgehend ungenutzt. Dabei fällt mit den passenden Frameworks die Programmierung passender Anwendungen gar nicht schwer.”

Meteora+ hits the App Store

Sunday, November 13th, 2011

The first gesture-controlled 3D airplane game has finally landed in the App Store. The objective is simple: Board the plane and collect the portals in the magical forest!

You can tilt your device like a steering wheel or, on devices with a front-facing camera (such as the iPhone 4/4S or iPad 2), even use gestures to manoeuvre the plane.

Gesture control works by tracking two objects and their respective position. Object recognition is based on color, so ensure the objects tracked have a distinct color from everything else in the picture (face, background, etc.) and you are in an evenly lit environment. For this purpose, colored gloves seem to work particularly well.

Gesture Control in Meteora+

The game, originated from two University projects, brings camera-driven interaction to mobile devices in the form of an addictive arcade game for people of all ages. An early preview of this still very young technology was shown in Frankfurt am Main at Macoun 2011, the biggest iOS and Mac developers’ conference in the German-speaking world.

Meteora+ ($3.99) is now available on the iTunes App Store.

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!

Macoun

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: www.macoun.de):

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 :)

Meteora – 3D iOS Game

Monday, April 25th, 2011

For the module Animation Software Development, I recently developed a 3D game for iPhone, iPod touch and iPad. It is fully data-driven and uses Lua and irrlicht. There is also a full report available for download below. It contains the initial design, concept drawings, explanation of algorithms and technologies used.

Meteora Teaser

The game currently features 5 levels, each 45 s long. They all differ in the speed of the airplane and the amount of obstacles (so far mainly trees). I plan on releasing this to the App Store at some point in time. However, I still need to add more level packs and add things like Game Center integration so players can submit highscores.

Gesture Library + Head Tracking prototype on iPad 2 [Update]

Monday, April 18th, 2011

I’ve spent a couple of days porting my gesture library to iOS to do some tests with the iPad 2’s front-facing camera. I also added head tracking with OpenCV for Head-Coupled Perspective (HCP) and a sort of 3D effect. It’s an early prototype for an ongoing project at the NCCA, still a lot to do, but I thought I’d give you a short preview. Stay tuned! The system is implemented in C++ and some Objective-C (for iOS glue code), powered by openFrameworks.


Update: New video showing an updated version with some new functions like the feature in the end that could be used for some sort of AR shooter game.


Update 2: Thanks to Renato Mitra for featuring this video on his site, one of the most popular blogs in Switzerland. Salü Äpflblog-Bsüecher :-)

Dice have been rolled, over 6000 times …

Tuesday, April 12th, 2011

After being a busy with studies and, to be honest, a lazy blogger, I want to start catching up and share some projects and new numbers with you. As you know, “Roll it!” has been on Apple’s AppStore  Since the end of 2009. I’m happy to let you know that so far it has made it’s journey to over 6000 iPhones, iPod touches and iPads in more than 30 countries.

Another great thing is that since the introduction of Game Center support, hundreds of players are competing online, every day.

Thanks to everyone for their support. Of course, you can still get it in case you haven’t tried it out already. Have fun and as always – keep on rollin’!

Available on the App Store

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.

Roll it! for iPad

“Roll it!” keeps on rollin’ …

Tuesday, January 19th, 2010

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.
