Once the main game structure was decided and programmed on the game boards, the team was ready to make the first open air tests. Two games were tested, with Philipp, Tamer and Simon being the game masters and Utku the player.
Wunderkammer Wien was programmed on an Arduino board with a GPS attached. The predefined curiosities were stored in the board, and an LED blinked with different intervals, responding to the vicinity of the player and triggering riddles. Game masters, in return, gave the riddles to Utku, some in form of audio and some in text. It was observed that textual riddles were quite challenging, whereas audio cues were quite stronger. One other factor was the urban space that defined the complexity: Curiosities on open square were much more difficult to find, than the ones in narrow and small streets.
im Untergrund test was built upon a RaspberryPi plus GPS board, playing audio tracks based on the location data. GPS proved to be very problematic during this test, while accuracy in the streets was so low that the game was simply not working. Only at the last point, which is in park area, the audio trigger was perfect on time and location. When this process was fluent, though, the experience was quite magical.
