Tutorials

The role of the tutorials is to provide a platform for a more intensive scientific exchange amongst researchers interested in a particular topic and as a meeting point for the community. Tutorials complement the depth-oriented technical sessions by providing participants with broad overviews of emerging fields. A tutorial can be scheduled for 1.5 or 3 hours.

Cross-Platform App Development: Options and Strategies

Abstract
The market for mobile devices is fragmented into various platforms. Android, Blackberry, iOS, Symbian and Windows Phone/Mobile all hold relevant market shares. Even though Android and iOS are prospective survivors of the extremely dynamic market, it is hard to estimate future figures. Developing applications for mobile devices traditionally requires developers to either develop a native app separately for each platform or to use a Webapp. The later does not have a look&feel like native apps of a platform and in many cases cannot utilize a device's full functionality. In general, several platforms should be supported due to users' (in many cases customers') demands. Therefore, either high effort and costs or limited usability have to be accepted.

A number of cross-platform development approaches have become available. They greatly differ in the underlying technology and approach. Some are mature while others are – to be optimistic – experimental. In particular, not all of them work in any situation. At the same time, Webapps have become more versatile with technologies such as HTML5 enabling access to device-specific features.

Our three hour tutorial will
  • introduce the problem and explain why native capabilities might be desired,
  • distinguish the currently available approaches theoretically,
  • present a number of existing implementations of these approaches,
  • give advice when these tools might be used and how to proceed with using them,
  • give some hints of further implementations that you should not yet use, and
  • share early best practices with you and give a future outlook.

After attending the tutorial, you will have an idea which technologies might be worth consideration when you create your next app and how to assess them with regard to the requirements towards your app project.

Biography of Gero Herkenrath
Gero Herkenrath is a PhD student and research assistant at the Department of Computer Science of RWTH Aachen University. He works at the Media Computing Group, the university's chair for human-computer interaction. Gero graduated from RWTH Aachen University in 2008 with a diploma in Computer Science. His research included bendable interfaces and he currently specializes in location-aware games and mobile guide systems. At the moment he is developing the "Aixplorer II", a city-wide guide system for tourists that combined indoor and outdoor navigation in and between museums and various points of interest all over Aachen. On the same platform he implements a location-aware game called "Aachen Horror" (working title).
