Projektthema
Der Kurs befasst sich mit der Gestaltung und Entwicklung einer interaktiven Anwendung,
die im Kontext von Ausstellungen, Museen oder Messen Wissensgebiete verständlich
erfahrbar macht.
Inhalt des Faches Ziel ist das Kennenlernen grundlegender Zusammenhänge im Bereich der Mensch-Computer-Interaktion und der Informationsgestaltung. Die Studenten befassen sich mit grundlegenden Interaktionsformen und medienspezifischen Gestaltungsproblemen, der Beziehung von Text, Bild und Animation sowie der protoypischem Umsetzung oder Simulation solcher Anwendungen.
Our interactive application features two 3D-printed models: a Tyrannosaurus Rex and a Diplodocus. These models have magnets integrated into their bases, allowing users to interact and navigate through the exhibit to access various pieces of information.
Sensors beneath the wooden tabletop detect the magnets in the bases of the figures. When a figure is placed on a portal, the sensors trigger a change in the content displayed on the screen, enabling the user to access specific information associated with that portal.
Arduino LEONARDO
The project utilizes an Arduino Leonardo connected to five hall sensors. The Leonardo was chosen over the Arduino Uno due to its native USB support, which is essential for emulating a keyboard or mouse. This feature was crucial for capturing and processing data from the hall sensors to simulate keyboard input.
Challenges
Calibration Issues
Precise calibration was required for the hall sensors.
Minor deviations in sensitivity settings could lead to incorrect readings.
Inconsistent Readings
Environmental factors like temperature and humidity affected sensor readings.
Frequent recalibration was necessary to maintain consistent performance.
Software Limitations
The Arduino platform’s analog-to-digital conversion resolution was sometimes insufficient.
Managing multiple sensors simultaneously required careful coding to prevent conflicts.
Physical Constraints
The wood layer’s thickness and material properties dampened magnetic fields.
Finding an optimal balance between wood thickness and sensor sensitivity was crucial.
