Media Informatics



We acknowledged today from Mr. Jens Trompeter, Board Member in Itemis company, that there's more in SCRUM than just that we learned from the Agile Lab and OOSC class: we had the opportunity to get real life, production-grade advices on how actually this technique (who is used to manage the projects) can help companies to finish projects in a timely and budget manner.

In the Autumn of 2008 I joined the Media Informatics Master program, saying goodbye to Alensa Online team. It is part of the Bonn-Aachen International Center for Information Technology (B-IT) and was created through the collaboration of prestigious German institutions: University of Bonn, RWTH Aachen University, University of Applied Sciences […]

No method is perfect – GPS needs clear sky, aGPS improves this but still needs some satellites to be seen, GSM works like a charm if you have lots of antennas but falls dramatically if you’re in a remote place and WiFi positioning is good in cities, but absolutely lacks in remote zones. Only the composition of all can cover all the situations encountered in a normal life – crowded city when going to work and big, empty spaces when going to mountains to relax.

Latest additions :sounds in our application, allowing user to get auditive feedback, background and confirmation for hit sounds for improving the User Experience, creating an immersive experience who tries to transpose the user into the real wood atmosphere, self generating levels, allowing users to improve themselves beyond our ideas about their possibilities: the user gets 60 seconds levels in which he has to hit more and more animals as he becomes better in targeting ( and in ball retrieval :-) ), changed the aspect ratio of the game from 4:3 to 16:9 to bette use the whiteboard's surface

Latest Flash UI changes


Since last week the Flash application changed- I added support for numerical keys for hitting. We mapped the numerical keys 1 to 6 to the 6 animals positions that can be hit. This way, it is enough to press a key to simulate the throw of a ball.The reason behind this application architectural change is that we needed an smart way to simulate the sensors that were hit, without actually having the entire setup in our workplace.

iMeet application is ready. I am very proud of this application, as it represents my achievements in fast learning and adapting to: new way of programming, as XCode and Interface Builder truly represent the ModelViewController paradigm; new language- Objective-C, which as any language has its pluses and minuses; new device: mobile devices on which I didn’t work since my experience on Sales Force Automation in TotalSoft company, back in 2005, on Windows CE.

Adding the points to the map is not as intuitive as it might seem, so let’s start by creating a new class called POI – point of interest. Assuming that we have the Latitude and Longitude as NSStrings, we check if they are filled. Then I create the CLLocationCoordonate2D which basically is a tuple of two doubles and then create the point of interest.

This week we work also on the User Interface - the Flash GUI. It was challenging sinceI haven't previous experience in creating games in Flash. The application creates 4 spots in the bottom of the scene and 2 in the top to show randomly an new animal each time one is hit. This areas are hit areas designed to respond to phisical sensors placed on the back of the board on which the Flash Game will be projected.

From time to time, you’ll need to show in your iPhone application a view over the entire application without navigating and destroying your workflow of the application. I’ll present the mechanism of modal windows as it is implemented in Cocoa Touch. Lets take a real case: you have a view […]
