Dual is a virtual reality dance performance where two dancers (Maria Lantin and Ken Perlin) create visuals and sounds for an audience. The dancers’ location and head orientation are tracked with a motion capture system. A controller held in one hand is also tracked.

The dancers see a different view of the world than that generated for the audience. The dancers’ view contains stage cues as well as movement guides for certain triggered events during the performance. The dancers see each other as oriented avatar heads with one tracked hand. The audience see┬áthe dancers as representations of black holes circling each other.
