Museum of the moment: A cooperation project between metropolitan culture and geomatics

In the art scene, low-cost sensors like Arduino are often being used to create or support a range of different effects. Live-Art installations must be often made very favorably due to low budget. In this article the function of a module for orientation is being described as it works in an artistic project, a Ph.D. - thesis is based on. The project is based on different people´s memories and stories. “Museum of the moment” deals with the aesthetic effects of performative collections such as the various visual animations of people´s memories. Different people are being videotaped while describing important moments in their lives. These portraits are being presented on large screens in the gallery. The viewers equipped with radio-controlled headphones look at the images and also listen to the different stories, not necessarily knowing who of the portrayed people has told which story. The orientation module based on the Arduino is supposed to identify the screen automatically and communicate with the acoustic server, in order to create the effect, that only the screen, that is being looked at by the viewer will trigger an acoustic signal which is the story that the viewer can listen to. Arduino is being used in this setting to enable orientation in the gallery space in the first place. Secondly, it makes sure to identify positions. Arduino-Nanos with a MPU 9150 are being used. These include an accelerometer, gyroscope and magnetic field sensor. To set and identify positions Wi-Fi is being used. Therefore signal strength and fingerprinting algorithms were examined. The final configuration of the screens does not necessarily need an estimation of position.
