One of the experiences gained in ebbits is that organising hackathons is a good way of testing the developed software.
The ebbits project participated in three hackathon events – Campus Party 2013 in London, organised by O2/Telefonica, the Green Hackfest 2014 in Utrecht, organised by TheHackfest and UtrechtInc, and a Fraunhofer FIT hackathon in Sankt Augustin in February 2015.
- Hackathons are great. You get immediate and high-value feedback on the developed technology which is one of the major reasons for creating a hackathon challenge. You see how people not involved in your project use the technology provided, and you can use their feedback to improve the results of your project, says Senior Project Manager, Alexander Schneider from Fraunhofer FIT.
Campus Party Europe
At the Campus Party Europe 2013 hackathon, six projects participated in the ebbits hackathon challenge which was to create innovative solutions for the food traceability domain.
The winning team provided two apps with a different focus.
One app supported the end user in quickly finding the meat that matches his preferences best. The user can select his preference (e.g., high fat/low fat, organic/conventional, pork/beef) and by scanning the barcode, the app quickly gives a green light or red light if the piece of meat matches the preferences.
- The innovative aspect was that the app also provided the producers with the selected preferences so they can match the beef production with the consumer behaviour, Alexander Schneider says.
The other app provided an algorithm for calculating a quality score for the scanned piece of meat depending of the number of events detected. Therefore the quality rating would be reduced if a large number of transport events or loading/unloading were detected because changes in temperature influence the meat quality.
- The time the meat is on offer on the supermarket shelves would degrade the quality. One can envision that an innovative algorithm for these quality changes could be implemented to inform the customer about the quality level, Alexander Schneider says.
The theme for the Green Hackfest was applied sustainability. The ebbits challenge was to create a mobile app (or clickable prototype) in the domain of a green factory where products are assembled on a production line. The winning team from Belgium provided a prototype on “Benchmarking of factories” and “Predictive Maintenance”. The prototype featured innovative benchmarking integration across factories and between lines in same factory. It also provided visual support for real-time monitoring in combination with an energy consumption benchmark.
Hackathon at Fraunhofer FIT
At the ebbits hackathon at Fraunhofer FIT, students were given the task to provide support for developers of IoT applications.
- The winning team provided a solution where a domain model can be mapped with a business process model in a very easy to use and user friendly way. It provides a good overview of which sensors were mapped to which business process steps and checks whether all sensors are already connected, Alexander Schneider explains.
