Gesture Recognition and Dance

Recently premiered at the Tate Modern,? the performance piece “Echo” generates a pointcloud via gesture recognition technologies that both represents the dancer’s movements and interacts with them.? According to the developers, the team,? UnitedVisualArtists, used an LED screen, the Lighthouse R10 LED screen, 8m wide by 11m high along with Point Grey Lab Bumblebee2 stereo camera system, mounted at the foot of the stage, in concert with their own proprietary software (dragonfly3) to render the resulting 3D point-cloud in real time. The motion of the ‘virtual camera’ was scripted within D3.
