The video shows the an early test application that was created from the one shipped with Skeltrack, then some testing with colleagues at Igalia’s office and finally the installation in Berlin and the final result:
The museum commissioned the Berlin’s interaction/design Studio Kaiser Matthies to create an installation so the studio created the concept and teamed up with us to develop the technical part.
The installation’s purpose is to show different forms of communication and the concept is very simple: When a user is detected in the “action zone”, an actor shows up in a screen and performs a salutation; the user is supposed to do the same salutation and receives a positive feedback if it was performed well or a negative feedback otherwise.
Examples of gestures are the Japanese bow or waving a kiss.
Salutations installation in the Museum für Kommunikation, Berlin
The screen in the right side shows a live video of users so they can compare their gestures with the ones expected from another person’s perspective.
For user detection and to know where their skeleton’s joints are, we used Skeltrack. We also used OpenCV on top of it in order to track more complex salutations, such as the US East Coast hand’s sign.
As for the rest of the stack, we used a minimal Debian, Clutter and GStreamer with many mechanisms to make it robust in case of failure and all this running from a USB stick.
This means that the software used in this installation is completely Open Source and more importantly, it is the world’s first interactive installation that uses Open Source skeleton tracking. We are also going to release the very application’s source code once we have time to release it.
We would like to thank Studio Kaiser Matthies for the opportunity of having such an important project in one of the world’s art capitals. Be sure to visit the museum the next time you’re in Berlin and, if you want us to help you do awesome interactive installations using Open Source software, let me know.
