The Charged room is an overall term for Opera Mecatronica-technologies, when cameras are connected to custom built software in order to transform spatial movement to sound and music.

2. Coloratura Machine: Opera singers interacting with their own voice

3. Opera singers interacting with each other through the triggering of sampled accompaniment music

4. Observer system. Interacting with the voice of Maria Callas and the voice of Zinka Milanov
