“BSQ” is an interactive LED wall in a clubhouse near “West Lake” of Hangzhou, China.
In the video, “Qiantang River” was crossing the city. The modern building will transform to ancient architecture when touched by people. If someone walks along the wall, some wave will follow him. The background sound also reacts to people’s interaction.
The project used two HOKUYO URG-10LX Scanning Laser Rangefinders, one for multi-touch, and another for tracking people’s position.
About software, python got the tracking data from Rangefinder, and sent it to Max (aka MaxMSP) through OSC, then Max used it to react with the visual and sound part.
Contra was responsible for Max development.
